docs+test(hierarchies): end-to-end review follow-ups (M5/M6/M7)

Findings from a 3-lens end-to-end review (correctness, security, tests).
Security review came back clean (cross-repo authz sound, isolation intact,
M5 gate sound modulo the documented manifest-trust boundary). No behavior
changes here — only accuracy + coverage:

- apply_service Phase B2: correct the descendant-expansion comment. The chain
  is COMMITTED ancestry (ancestors() reads the pool), so a reparent in the same
  apply takes effect next apply — same "one more apply" shape the in-tree path
  and group-create reparenting already have. Authz stays sound: the gate and the
  expansion consume the SAME chain (checked == written).
- doc §4.5: document the two known "one more apply / no data risk" limitations
  — reparent-in-same-apply template resolution, and the `{env}` source split
  (declared apps use --env; cross-repo descendants use apps.environment).
- approval journey: give the app real (`[vars]`) content so the editor member's
  AppVarsWrite is actually exercised — the admin-gate test now proves approval
  is ABOVE editor-write, not just "any non-admin is refused". (Vars cascade with
  the app; scripts are ON DELETE RESTRICT and would break AppGuard teardown.)
- templates journey: assert descendant expansions are idempotent (stable row
  ids on re-apply — no churn), matching the in-tree guarantee.

+# PiCloud Codebase Audit — 2026-06-07
+
+**Scope:** `main` at v1.1.9 head, commit `450bada`.
+**Methodology:** Multi-agent audit — orchestrator + 6 parallel subagents sliced by (Security data-plane, Security auth/secrets, Performance, Code Quality, UI/UX, Migration+TS client). Reviewer-verified on the highest-severity findings (Q-001, T-001, U-006, P-001, P-004, S-002).
+**Categories:** Security (S), Performance (P), Code Quality (Q), UI/UX (U), Migration/Schema (M), TypeScript client (T).
+
+## Executive summary
+
+- **One Critical: the manager-core / orchestrator-core boundary has inverted.** `manager-core/Cargo.toml` depends on `picloud-orchestrator-core` and the dispatcher / route_admin / apps_api / repo modules reach into `RouteTable`, `ExecutionGate`, `ExecutorClient`, `ScriptResolver`, and `InProcessBroadcaster` for **behavior**, not just DTOs. CLAUDE.md's "Working Rules" call this exact pattern the bright line that keeps cluster mode a swap-not-rewrite. Today it's a swap-and-rewrite. See [F-Q-001](#f-q-001--manager-core-depends-on-orchestrator-core-for-behavior-reversing-the-architectural-arrow).
+- **Load-bearing risk: every stateful Rhai SDK service silently accepts unbounded payloads.** `kv::set`, `docs::create/update`, `pubsub::publish_durable`, `queue::enqueue` — none of them cap value size. Files + secrets + email have caps; the other four do not. An anonymous public-HTTP script can OOM Postgres JSONB columns or amplify one publish into N outbox rows × M MB each. See [F-S-001](#f-s-001--unbounded-payload-sizes-on-kvset-docs-pubsubpublish_durable-queueenqueue).
+- **Biggest performance leak: Argon2id on the async worker, on the hottest paths.** `attach_principal_if_present` middleware runs an Argon2 verify per API-key candidate for every request carrying a Bearer header (including the data plane). Login and password reset do the same on async workers. Compounded by an unspawned-blocking call and no rate limit, the auth surface is one DoS vector for memory and three for CPU. See [F-P-002](#f-p-002--argon2id-password--api-key-verify-runs-synchronously-on-the-tokio-async-worker), [F-S-006](#f-s-006--api-key-bearer-creates-argon2-cpu-amplifier-for-arbitrary-callers).
+- **Pool sized for 10, gate sized for 32.** `init_db` opens `max_connections = 10`; the execution gate defaults to 32. Pool starvation under load is not a question of if. See [F-P-003](#f-p-003--postgres-pool-max_connections10-vs-executiongate-default-32).
+- **Most user-visible UX gap: the dashboard can't create half the trigger kinds.** Backend exposes create for KV/docs/files/dead-letter triggers; the dashboard lists them but ships create forms only for cron/pubsub/email/queue. Operators must hit the API directly. See [F-U-001](#f-u-001--dashboard-cannot-create-kvdocsfilesdead-letter-triggers). The queues drilldown also has a broken link that 404s — [F-U-002](#f-u-002--queue-drilldown-links-to-a-non-existent-app-scoped-scripts-route).
+- **A handful of dashboard pages render in light-theme fallback colors on a dark-theme app.** Dead-letters, Files, App-Users, Invitations, Queues all reference `var(--name, #fff)` style fallbacks for CSS variables the dashboard never defines, so users see `#666` text on `#0f172a` backgrounds. See [F-U-004](#f-u-004--five-dashboard-pages-render-light-theme-fallback-colors-on-the-dark-theme-app).
+- **TypeScript client has a Rules-of-Hooks violation.** `useEndpoint().get()` / `.post()` returns hook-calling functions; calling them conditionally or both in the same component produces undefined state. The test suite doesn't exercise it. See [F-T-001](#f-t-001--useendpoint-violates-react-rules-of-hooks).
+- **The cleanest surface is the migration set.** 35 sequential migrations with consistent FK-cascade discipline, partial indexes that match their predicates, and a working schema-snapshot test. Findings here are largely "redundant index" or "missing belt-and-suspenders CHECK" — refinement, not breakage.

+## Findings
+
+### Security
+
+#### Critical
+
+_(See Code Quality for the only Critical finding — the manager-core ↔ orchestrator-core boundary breach.)_
+
+#### High
+
+##### F-S-001 — Unbounded payload sizes on `kv::set`, `docs::*`, `pubsub::publish_durable`, `queue::enqueue`
+- **Severity:** High
+- **Location:** [crates/manager-core/src/queue_service.rs:33-92](crates/manager-core/src/queue_service.rs#L33-L92), [crates/manager-core/src/kv_service.rs:93](crates/manager-core/src/kv_service.rs#L93), [crates/manager-core/src/docs_service.rs:107](crates/manager-core/src/docs_service.rs#L107), [crates/manager-core/src/pubsub_service.rs:138](crates/manager-core/src/pubsub_service.rs#L138)
+- **Summary:** Four stateful SDK services accept any JSON value and write it straight to a `JSONB` column with no size validation. Files (per-file cap, env-overridable), secrets (64 KB default), and email (25 MB default) all enforce limits; these four don't. An anonymous public-HTTP script can fill disk via `queue::enqueue` (up to Postgres's ~1 GB JSONB limit per row), or amplify a single `publish_durable` into N outbox rows × payload bytes. Fix shape: add a per-service `max_value_bytes` config (default ~256 KB) validated at the service entry, before authz/repo. Mirror the existing `MAX_VALUE_BYTES` constant pattern in `secrets_service.rs`.
+
+##### F-S-002 — `users::request_password_reset` and `send_verification_email` are unrate-limited and reachable from anonymous scripts
+- **Severity:** High
+- **Location:** [crates/manager-core/src/users_service.rs:633](crates/manager-core/src/users_service.rs#L633), [crates/manager-core/src/users_service.rs:575](crates/manager-core/src/users_service.rs#L575)
+- **Summary:** Both methods short-circuit the authz gate when `cx.principal == None`. An attacker who can call any public route can trigger unbounded outbound email per call to arbitrary or attacker-supplied addresses — exhausting SMTP-relay quota, getting the relay blacklisted, or burning provider credits. No per-app rate limit, per-recipient cooldown, or per-execution counter. Fix shape: token-bucket rate limit keyed on `(cx.app_id, recipient_email)`, with a per-app daily cap. Optionally require `cx.principal.is_some()` when invoked from a public route.
+
+##### F-P-001 — `users::list` N+1: one `fetch_roles` query per user row
+- **Category:** Performance
+- **Severity:** High
+- **Location:** [crates/manager-core/src/users_service.rs:466-471](crates/manager-core/src/users_service.rs#L466-L471)
+- **Summary:** `list` page-fetches users then loops calling `self.fetch_roles(cx.app_id, row.id)` — one query per user. Default limit 50, max 500, so the admin "users" page does 51-501 round-trips. The same `fetch_roles` is also called from `verify_session_for_realtime` (one extra query on every authenticated SSE subscribe). Fix: add `AppUserRoleRepo::list_for_users(app_id, &[user_ids])` returning a `HashMap<AppUserId, Vec<String>>` and join in a single query (`WHERE user_id = ANY($2)`).
+
+##### F-P-002 — Argon2id password / API-key verify runs synchronously on the Tokio async worker
+- **Category:** Performance
+- **Severity:** High
+- **Location:** [crates/manager-core/src/auth_middleware.rs:206-208](crates/manager-core/src/auth_middleware.rs#L206-L208), [crates/manager-core/src/auth_api.rs:98](crates/manager-core/src/auth_api.rs#L98), [crates/manager-core/src/users_service.rs:502](crates/manager-core/src/users_service.rs#L502)
+- **Summary:** `verify_password` (Argon2id default params: m=19456 KiB, t=2) is CPU-bound at tens-to-hundreds of ms and is invoked synchronously on the Tokio worker. Worse, `verify_api_key` Argon2-verifies **every** candidate sharing the 8-char prefix on **every** authenticated `/api/v1/admin/*` request — a single hot user with N keys serializes every admin request behind N×Argon2 verifies. Fix: wrap each verify in `tokio::task::spawn_blocking`, and maintain a short-lived (60-300s) cache `LruCache<(prefix, raw)→user_id>` so a hot API key doesn't re-Argon2 every request.
+
+##### F-P-003 — Postgres pool `max_connections=10` vs `ExecutionGate` default 32
+- **Category:** Performance
+- **Severity:** High
+- **Location:** [crates/picloud/src/lib.rs:583-588](crates/picloud/src/lib.rs#L583-L588) vs [crates/orchestrator-core/src/gate.rs](crates/orchestrator-core/src/gate.rs)
+- **Summary:** `init_db` hard-codes `max_connections(10)`. The execution gate allows 32 concurrent script executions, each doing multiple sequential DB calls (script resolve, every SDK call inside the script, log sink, outbox emit), plus the dispatcher tick every 100ms, the cron tick, three GC sweeps, and the auth middleware running per request. Pool starvation manifests as `acquire_timeout` (5 s) errors and tail-latency spikes. Fix: scale `max_connections` to roughly `gate.max_permits × estimated_queries_per_exec + headroom`, expose a `PICLOUD_DB_MAX_CONNECTIONS` env knob, and document the relationship.
+
+##### F-P-004 — `LocalExecutorClient::execute` and `invoke()` re-entry recompile AST every call
+- **Category:** Performance
+- **Severity:** High
+- **Location:** [crates/orchestrator-core/src/client.rs:178-216](crates/orchestrator-core/src/client.rs#L178-L216), [crates/executor-core/src/sdk/invoke.rs:192-200](crates/executor-core/src/sdk/invoke.rs#L192-L200)
+- **Summary:** Two code paths bypass the AST cache: `ExecutorClient::execute` (used in tests + fallback) calls `engine.execute(&source, req)` which compiles inline; and `invoke()` synchronous re-entry calls `self_engine.execute(&resolved.source, req)`, re-parsing every callee on every invoke. Composed workflows multiply parse cost by depth. Fix: have `InvokeService::resolve` return `(ScriptIdentity, source)` and route through the cached `LocalExecutorClient::get_or_compile`, or expose `Engine::execute_with_identity` so the engine itself can cache.
+
+##### F-P-005 — `execution_logs` admin list uses `OFFSET` pagination
+- **Category:** Performance
+- **Severity:** High
+- **Location:** [crates/manager-core/src/repo.rs:511-535](crates/manager-core/src/repo.rs#L511-L535)
+- **Summary:** `list_for_script` does `ORDER BY created_at DESC LIMIT $2 OFFSET $3`. Postgres has to scan + discard `OFFSET` rows on every page; deep pages get linearly slower. Sister tables in the same repo all use cursor pagination. Fix: switch to keyset cursor on `(created_at, id)` — `WHERE script_id=$1 AND (created_at, id) < ($cursor_ts, $cursor_id)`. Same shape as every other list endpoint.
+
+##### F-P-006 — `queue::depth` / `depth_pending` are `COUNT(*)` reachable per script call
+- **Category:** Performance
+- **Severity:** High
+- **Location:** [crates/manager-core/src/queue_repo.rs:264-287](crates/manager-core/src/queue_repo.rs#L264-L287), [crates/manager-core/src/queue_repo.rs:289-322](crates/manager-core/src/queue_repo.rs#L289-L322)
+- **Summary:** Scripts call `queue::depth(name)` / `queue::depth_pending(name)` per invocation; each is an unbounded `COUNT(*)` over the queue_messages partial index. On a backed-up queue with millions of rows, every call scans the whole partition. `list_for_app` (dashboard queue overview) does 3× `COUNT(*) FILTER (...)` in one pass — same scan magnified. Fix: maintain per-`(app_id, queue_name)` running counters in a small table (incremented on enqueue, decremented on ack/dead-letter), or downgrade `depth()` to a presence check (`SELECT 1 … LIMIT 1`).
+
+##### F-P-007 — Dispatcher tick loops queue consumers serially (one claim per consumer per tick)
+- **Category:** Performance
+- **Severity:** High
+- **Location:** [crates/manager-core/src/dispatcher.rs:152-164](crates/manager-core/src/dispatcher.rs#L152-L164), [crates/manager-core/src/dispatcher.rs:166-290](crates/manager-core/src/dispatcher.rs#L166-L290)
+- **Summary:** `tick_queue_arm` calls `list_active_queue_consumers()` then iterates serially, awaiting one `queue.claim(app, queue)` per consumer per tick. With N queue consumers and a 100ms tick, worst-case throughput is `N × (claim + executor) / tick`. Each iteration is a full `dispatch_one_queue` (resolve script, resolve principal, executor round-trip) sequential on the dispatcher's task. Fix: bound concurrency with `futures::stream::iter(consumers).for_each_concurrent(N, …)` (the execution gate caps anyway), and/or cache the consumer list across ticks.
+
+##### F-P-008 — `TriggerRepo::list_for_app` is N+1 — one detail-table query per parent row
+- **Category:** Performance
+- **Severity:** High
+- **Location:** [crates/manager-core/src/trigger_repo.rs:971-987](crates/manager-core/src/trigger_repo.rs#L971-L987) (calls `hydrate_one` at ~:1351 per row)
+- **Summary:** `list_for_app` selects parent rows then for each one issues a `SELECT … FROM <kind>_trigger_details WHERE trigger_id = $1`. For N triggers on an app, that's N+1 queries on every dashboard `GET /apps/{id}/triggers` load. Fix: split by kind and issue one-per-kind `JOIN <details> ON details.trigger_id = t.id WHERE t.app_id=$1 AND t.kind='<k>'`, or write a single CTE with LEFT JOIN to each `*_trigger_details` table.
+
+##### F-P-009 — `attach_principal_if_present` runs on every data-plane request, including paths that don't need auth
+- **Category:** Performance
+- **Severity:** High
+- **Location:** [crates/manager-core/src/auth_middleware.rs:141](crates/manager-core/src/auth_middleware.rs#L141), [crates/manager-core/src/auth_middleware.rs:192-229](crates/manager-core/src/auth_middleware.rs#L192-L229)
+- **Summary:** Every request hitting `/api/v1/execute/...` or any user-route path goes through `attach_principal_if_present`. If the request carries any `Authorization: Bearer pic_...` header, the middleware does: prefix lookup + Argon2 verify per candidate + `admin_users.get` + `touch_last_used` UPDATE. Three DB round-trips + Argon2id per request — on a path that may not need authz at all. Fix: short-circuit when the route doesn't require auth; add a sliding-window cache of `(token → principal)` valid for 60-300s.
+
+##### F-Q-001 — `manager-core` depends on `orchestrator-core` for behavior, reversing the architectural arrow
+- **Category:** Code Quality
+- **Severity:** Critical
+- **Location:** [crates/manager-core/Cargo.toml:13](crates/manager-core/Cargo.toml#L13), [crates/manager-core/src/dispatcher.rs:28](crates/manager-core/src/dispatcher.rs#L28), [crates/manager-core/src/route_admin.rs:15](crates/manager-core/src/route_admin.rs#L15), [crates/manager-core/src/apps_api.rs](crates/manager-core/src/apps_api.rs), [crates/manager-core/src/invoke_service.rs:15](crates/manager-core/src/invoke_service.rs#L15), [crates/manager-core/src/pubsub_service.rs:519](crates/manager-core/src/pubsub_service.rs#L519)
+- **Summary:** CLAUDE.md's bright line: "the orchestrator never imports `executor-core` directly — define a trait in `shared`". The same rule should hold for `manager-core ↔ orchestrator-core`. Instead, `manager-core` pulls `picloud_orchestrator_core::routing::{RouteTable, AppDomainTable, matcher::CompiledRoute, pattern, conflict}` plus `{ExecutorClient, ExecutionGate, ScriptIdentity, ScriptResolver, ResolverError, InProcessBroadcaster}`. `RouteTable` is a stateful `Arc`'d object with methods (`replace_all`, `match_request_for_app`) — not a DTO. This kills the cluster-mode swap: when manager and orchestrator are separate binaries the control plane shouldn't link the orchestrator's routing-table impl. Fix: move `RouteTable`, `AppDomainTable`, `CompiledRoute`, `CompiledAppDomain`, `ScriptResolver`, `ResolverError`, `ExecutorClient`, `ExecutionGate`, `ScriptIdentity`, and the broadcaster trait into `shared/` (traits + DTOs); keep only in-process impls in `orchestrator-core`.
+
+##### F-Q-002 — Every SDK module open-codes its own `block_on` helper
+- **Category:** Code Quality
+- **Severity:** High
+- **Location:** [crates/executor-core/src/sdk/kv.rs:178](crates/executor-core/src/sdk/kv.rs#L178), [crates/executor-core/src/sdk/docs.rs:240](crates/executor-core/src/sdk/docs.rs#L240), [crates/executor-core/src/sdk/pubsub.rs:162](crates/executor-core/src/sdk/pubsub.rs#L162), [crates/executor-core/src/sdk/users.rs:593](crates/executor-core/src/sdk/users.rs#L593), [crates/executor-core/src/sdk/dead_letters.rs:69](crates/executor-core/src/sdk/dead_letters.rs#L69), [crates/executor-core/src/sdk/secrets.rs:138](crates/executor-core/src/sdk/secrets.rs#L138), [crates/executor-core/src/sdk/files.rs:266](crates/executor-core/src/sdk/files.rs#L266), [crates/executor-core/src/sdk/email.rs:136](crates/executor-core/src/sdk/email.rs#L136), [crates/executor-core/src/sdk/http.rs:369](crates/executor-core/src/sdk/http.rs#L369), [crates/executor-core/src/sdk/queue.rs:120](crates/executor-core/src/sdk/queue.rs#L120)
+- **Summary:** Ten SDK modules each define a near-identical `block_on` that grabs `TokioHandle::try_current()`, calls `block_on`, and wraps the error into `EvalAltResult::ErrorRuntime` with a service prefix. The shapes diverge only by which `Error` variant they pin and the prefix string. Promote `sdk::bridge::block_on::<E, F>(service_name, fut)` (or a `block_on_kind!` macro) — keeps each call site to one line and ensures uniform error formatting + a single point for future tracing instrumentation.
+
+##### F-Q-003 — Each stateful service open-codes the same `check_read` / `check_write` authz idiom
+- **Category:** Code Quality
+- **Severity:** High
+- **Location:** [crates/manager-core/src/kv_service.rs:48-64](crates/manager-core/src/kv_service.rs#L48-L64), [crates/manager-core/src/docs_service.rs:57-73](crates/manager-core/src/docs_service.rs#L57-L73), [crates/manager-core/src/files_service.rs:51-71](crates/manager-core/src/files_service.rs#L51-L71), [crates/manager-core/src/pubsub_service.rs:116-127](crates/manager-core/src/pubsub_service.rs#L116-L127), [crates/manager-core/src/queue_service.rs:61-68](crates/manager-core/src/queue_service.rs#L61-L68)
+- **Summary:** Every service has the same pattern: `if cx.principal.is_some() { authz::require(...).await.map_err(|_| <Service>Error::Forbidden) }`. That's 9 hand-rolled copies of the same 6-line idiom, each with its own error type. `users_service` does this slightly differently (returns `Repo` vs `Denied`). Promote a single helper `authz::script_gate<E>(authz, cx, cap, deny_to: impl Fn(AuthzDenied) -> E)`. Eliminates drift risk: e.g., `queue_service` maps to `Rejected("forbidden")` instead of `Forbidden` because there's no `Forbidden` variant — see F-Q-004.
+
+##### F-Q-004 — Sibling services have inconsistent error-variant shapes, and `QueueError` is missing `Forbidden` entirely
+- **Category:** Code Quality
+- **Severity:** High
+- **Location:** [crates/shared/src/kv.rs:139](crates/shared/src/kv.rs#L139), [crates/shared/src/queue.rs:60-77](crates/shared/src/queue.rs#L60-L77), [crates/shared/src/pubsub.rs:85](crates/shared/src/pubsub.rs#L85), [crates/shared/src/invoke.rs:110](crates/shared/src/invoke.rs#L110)
+- **Summary:** Same semantic error has two names: "Backend" in `KvError`/`DocsError`/`FilesError`/`SecretsError`; "Unavailable" in `QueueError`/`PubsubError`/`InvokeError`. Worse, `QueueError` has no `Forbidden` variant at all, so authz denial gets squashed into `QueueError::Rejected("forbidden".into())` ([queue_service.rs:68](crates/manager-core/src/queue_service.rs#L68)), losing the structured variant a 403-translation layer would need. And `queue_service::depth/depth_pending` skip authz entirely. Fix: pick one name (`Backend`), add `Forbidden` to every service's error enum uniformly, and gate `depth`/`depth_pending` on `AppQueueRead` (or document why they're public).
+
+##### F-Q-005 — Authz failures collapse `AuthzDenied::Repo` into `Forbidden` via `map_err(|_| …)`
+- **Category:** Code Quality
+- **Severity:** High
+- **Location:** [crates/manager-core/src/kv_service.rs:52,61](crates/manager-core/src/kv_service.rs#L52), [crates/manager-core/src/docs_service.rs:61,70](crates/manager-core/src/docs_service.rs#L61), [crates/manager-core/src/files_service.rs:55,68](crates/manager-core/src/files_service.rs#L55), [crates/manager-core/src/pubsub_service.rs:124,226](crates/manager-core/src/pubsub_service.rs#L124)
+- **Summary:** Every `check_read`/`check_write` uses `.map_err(|_| KvError::Forbidden)?` — collapsing both `AuthzDenied::Denied` AND `AuthzDenied::Repo(repo_err)` into `Forbidden`. A DB blip in the authz repo surfaces as 403 to scripts; operators can't distinguish "real forbidden" from "Postgres flap during permission check". `users_service::require` ([users_service.rs:177-181](crates/manager-core/src/users_service.rs#L177-L181)) gets this right by mapping separately. Apply the same pattern uniformly.
+
+##### F-Q-006 — `InboxRegistry::register` silently no-ops on lock poisoning, leaking a dead id
+- **Category:** Code Quality
+- **Severity:** High
+- **Location:** [crates/orchestrator-core/src/inbox.rs:46-53](crates/orchestrator-core/src/inbox.rs#L46-L53)
+- **Summary:** `register()` returns `(Uuid, Receiver)` even when the inner `Mutex` is poisoned — the `if let Ok(mut g) = self.inner.lock()` swallows the error, the sender is never inserted, the later `deliver(id, …)` will see no entry and return `Abandoned`. The caller's `await rx` blocks until the orchestrator's outer timeout. Sister registries `RouteTable` ([routing/table.rs:36](crates/orchestrator-core/src/routing/table.rs#L36)) and `AppDomainTable` correctly panic with `.expect("route table poisoned")`. Fix: switch to `expect("inbox poisoned")` and document the policy.
+
+##### F-T-001 — `useEndpoint` violates React Rules of Hooks
+- **Category:** Code Quality
+- **Severity:** High
+- **Location:** [clients/typescript/src/react/index.ts:73-101](clients/typescript/src/react/index.ts#L73-L101)
+- **Summary:** `useEndpoint(path)` returns `{ get: () => useResource(…), post: (body) => useResource(…) }`. Each of `.get()` and `.post()` calls `useResource`, which calls `useState` and `useEffect`. React's Rules of Hooks require hook calls in the top level of a component, in the same order each render. Calling `useEndpoint(path).get()` conditionally, or calling both `.get()` and `.post()` from the same component, will violate hook ordering and produce undefined behavior (state from one call leaking into the other). `react.test.tsx` doesn't exercise `useEndpoint` at all — only `useTopic` — so this is uncaught. Fix: refactor to a flat hook (`useEndpointGet(path)` / `useEndpointPost(path)`) with consistent hook order.
+
+##### F-U-001 — Dashboard cannot create KV, Docs, Files, or Dead-letter triggers
+- **Category:** UI/UX
+- **Severity:** High
+- **Location:** [dashboard/src/routes/apps/[slug]/+page.svelte:1092-1342](dashboard/src/routes/apps/[slug]/+page.svelte#L1092-L1342), [dashboard/src/lib/api.ts:771-801](dashboard/src/lib/api.ts#L771-L801)
+- **Summary:** Backend `triggers_api.rs` exposes `POST /apps/{id}/triggers/{kv,docs,files,dead_letter}`, but the dashboard's Triggers tab ships create forms only for cron, pubsub, email, and queue. Listing shows kv/docs/files/dead_letter rows (with `collection_glob` and `ops`) but operators can't create them from the UI. Add four more `submitCreate*` forms (collection glob + ops checkboxes).
+
+##### F-U-002 — Queue drilldown links to a non-existent app-scoped scripts route
+- **Category:** UI/UX
+- **Severity:** High
+- **Location:** [dashboard/src/routes/apps/[slug]/queues/[name]/+page.svelte:71](dashboard/src/routes/apps/[slug]/queues/[name]/+page.svelte#L71)
+- **Summary:** The consumer-script link is `{base}/apps/{slug}/scripts/{detail.consumer.script_id}` but the actual script detail route is `{base}/scripts/{id}` — there is no `apps/[slug]/scripts/[id]` directory. Clicking the consumer name 404s. Either move scripts under apps in the route tree (the breadcrumb on the script page already wants this), or fix the link to `{base}/scripts/{detail.consumer.script_id}`.

+##### F-U-003 — Files page has no collection list — operators must guess collection names
+- **Category:** UI/UX
+- **Severity:** High
+- **Location:** [dashboard/src/routes/apps/[slug]/files/+page.svelte:96-110](dashboard/src/routes/apps/[slug]/files/+page.svelte#L96-L110)
+- **Summary:** The Files page can only list a collection if you already know its name and type it in. There's no "browse known collections" affordance, no list endpoint (`GET /apps/{id}/files/collections` is missing in the backend too — flag for v1.1.10+), so first-time operators have no recourse. Minimum fix: show a hint listing collection-glob patterns drawn from any registered `files` triggers. Longer-term: backend endpoint to list known collections.

+##### F-S-003 — `users::find_by_email` exposes user existence to anonymous callers
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/users_service.rs:400-413](crates/manager-core/src/users_service.rs#L400-L413)
+- **Summary:** `find_by_email` requires `AppUsersRead`, which means anonymous public-HTTP scripts can call it (the gate short-circuits on `None`). An attacker hitting any public route can iterate emails to enumerate registered users, then pivot to `login` / `request_password_reset`. The reset path is silent-on-miss; `find_by_email` is not. Fix: require an authenticated principal for `find_by_email`, or document that scripts must wrap it in their own auth check before calling from a public route.
+
+##### F-S-004 — `request_password_reset` has an observable timing oracle for email existence
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/users_service.rs:646-651](crates/manager-core/src/users_service.rs#L646-L651)
+- **Summary:** Handler returns immediately when email shape is invalid or user is unknown; on found user it generates an Argon2 token, INSERTs into `app_user_password_resets`, builds a link, and calls `email.send` (tens of ms + DB write + SMTP RTT). The wall-clock delta is enormous and externally observable. Combined with F-S-003, this gives a reliable enumeration oracle. Fix: when no user matches, still do a dummy `generate_session_token()` and a dummy `email.send` (against `/dev/null` or a fixed sleep). Better: run the full code path unconditionally and discard the result on no-match.
+
+##### F-S-005 — `users_admin_api::delete_user` doesn't enforce `AppUsersAdmin` despite the brief
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/users_admin_api.rs:250-272](crates/manager-core/src/users_admin_api.rs#L250-L272)
+- **Summary:** Handler comment acknowledges the brief required `AppUsersAdmin` for the irreversible dashboard delete, but the implementation calls `service.delete(...)` which only gates on `AppUsersWrite`. v1.1.8 HANDBACK §7 lists this as known. Effect: any editor can delete app users via the admin HTTP API and dashboard button, not just admins. Fix: add an explicit `authz::require(... AppUsersAdmin(app_id))` before `service.delete`.
+
+##### F-S-006 — API-key bearer creates Argon2 CPU amplifier for arbitrary callers
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/auth_middleware.rs:192-211](crates/manager-core/src/auth_middleware.rs#L192-L211)
+- **Summary:** `verify_api_key` Argon2id-verifies every candidate sharing the 8-char prefix. An unauthenticated attacker can submit unlimited `Authorization: Bearer pic_<8>...` requests and force the server into per-request Argon2 (OWASP defaults: ~tens of ms each). A few hundred concurrent connections trivially DoSes the manager — the verify runs before any concurrency cap. The 32-byte random body has astronomical entropy, so Argon2 is overkill here. Fix: switch the key-verify hash to SHA-256 (high-entropy tokens don't need Argon2), cap the candidate set at a small constant (e.g. 16) and log when truncation occurs, and add per-IP rate limit at the reverse proxy.
+
+##### F-S-007 — No rate limit on `auth/login` — Argon2 verify is a memory DoS
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/auth_api.rs:74-101](crates/manager-core/src/auth_api.rs#L74-L101)
+- **Summary:** Login always runs Argon2 verify (timing-flat — good), but no rate limit, no failed-attempt lockout, no captcha. OWASP-default Argon2 cost (m=19456 KiB ≈ 19 MB RAM per verify) makes this a credible memory + CPU DoS: a few hundred concurrent `POST /admin/auth/login` exhausts manager memory. Combined with F-S-006, the auth surface has no brute-force defense. Fix: per-IP throttling at the reverse proxy (documented Caddy rate-limit module) and a per-username sliding-window lockout in `admin_user_repo`.
+
+##### F-S-008 — Realtime authority key cache never invalidates
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/realtime_authority.rs:34,56-72](crates/manager-core/src/realtime_authority.rs#L34)
+- **Summary:** `key_cache: Mutex<HashMap<AppId, Vec<u8>>>` is populated on first read and never evicted, bounded, or cleared on app deletion. (1) Once key rotation lands, every running process keeps accepting tokens signed by the old key until restart. (2) Today, if an operator drops and re-creates an app (FK CASCADE removes `app_secrets`, fresh row inserted), the cache hands out the **old** key bytes. Also unbounded growth on a many-app install. Fix: TTL on cache entries, rotation eviction hook, or simplify by removing the cache (DB lookup is cheap; only fires on subscribe).
+
+##### F-S-009 — `PICLOUD_DEV_MODE` deterministic master key is fatal if accidentally enabled in prod
+- **Severity:** Medium
+- **Location:** [crates/shared/src/crypto.rs:206-231](crates/shared/src/crypto.rs#L206-L231)
+- **Summary:** When `PICLOUD_DEV_MODE=true` AND `PICLOUD_SECRET_KEY` is unset, the master key becomes `SHA-256("picloud-dev-master-key-v1.1.7")` — a fully public value. The warning is correct but the gate is a single env var. An operator who copies a dev docker-compose file into prod silently encrypts everything with a world-known key. Fix: add a startup check that refuses dev mode when prod indicators are present (non-localhost `PICLOUD_PUBLIC_BASE_URL`, etc.), or require BOTH `PICLOUD_DEV_MODE=true` AND `PICLOUD_DEV_INSECURE_KEY=i-understand-this-is-insecure`.
+
+##### F-S-010 — Inbound-email HMAC verification has no replay protection
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/email_inbound_api.rs:83-144](crates/manager-core/src/email_inbound_api.rs#L83-L144)
+- **Summary:** Receiver verifies `HMAC-SHA256(secret, body)` constant-time — good. But the signature covers only the body. No timestamp binding, no nonce/idempotency check. A captured webhook request can be replayed indefinitely, re-firing the trigger and enqueueing duplicate executions. Industry standard (Stripe, Slack) includes a timestamp in the signed payload and rejects requests outside a ~5-minute window. Fix: add `X-Picloud-Timestamp` to the HMAC input, reject requests outside the configured window, and dedupe on `message_id` in a TTL'd cache.
+
+##### F-S-011 — `admin_sessions` has no `revoked_at` — password change can't invalidate live sessions
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/admin_session_repo.rs:1-152](crates/manager-core/src/admin_session_repo.rs#L1-L152)
+- **Summary:** Unlike `app_user_sessions` (v1.1.8 — has `revoked_at` and `revoke_for_user`), `admin_sessions` only has `expires_at` and a `delete_for_user(user_id)` helper. No admin-side "revoke all sessions" gesture; an admin password change must explicitly call `delete_for_user` (audit the flow to confirm it does). Fix: add a `revoked_at` column for explicit revocation distinct from TTL expiry, and add a "log out all sessions" action.
+
+##### F-S-012 — `invoke_async` has no authz check — anonymous scripts can fire any script in the app
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/invoke_service.rs:121-161](crates/manager-core/src/invoke_service.rs#L121-L161), [crates/executor-core/src/sdk/invoke.rs:86-110](crates/executor-core/src/sdk/invoke.rs#L86-L110)
+- **Summary:** `enqueue_async` and the sync `invoke()` perform no `authz::require` check — no `AppInvoke` capability exists. Same-app isolation is preserved (cross-app guard works), but within one app, an anonymous public-HTTP script can trigger any other script (e.g. an admin-only worker that hits secrets/files/external HTTP). Worse: `invoke_async` runs the callee with `principal: None`, so the callee may itself hold capabilities the original public caller shouldn't. Fix: add `Capability::AppInvoke(app_id)` and gate `invoke()` / `invoke_async()` on it; consider a "private" vs "public" script tag for the anonymous case.
+
+##### F-S-013 — `users::invite` accumulates pending invitations per email without dedup
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/users_service.rs:720-778](crates/manager-core/src/users_service.rs#L720-L778), [crates/manager-core/migrations/0030_app_user_invitations.sql:16-26](crates/manager-core/migrations/0030_app_user_invitations.sql#L16-L26)
+- **Summary:** No unique constraint on `(app_id, email)` for pending rows. Calling `users::invite("alice@…")` N times creates N rows with N valid tokens. Combined with `accept_invite` returning `Ok(None)` silently when the email already exists, an attacker who learns one invitation token can permanently consume it without effect. Fix: partial unique index `(app_id, lower(email)) WHERE accepted_at IS NULL` + handle conflict as 409 with "reissue?" UX.
+
+##### F-S-014 — Topic edit modal warns only on `internal → external` flip, not on any other permissive change
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/apps/[slug]/+page.svelte:1678-1722](dashboard/src/routes/apps/[slug]/+page.svelte#L1678-L1722)
+- **Summary:** Warning fires only for the internal→external transition (`editFlipToExternal`). Switching `token → public` or `session → public` while already external is equally risky (opens topic to anonymous subscribers) but produces no warning. Fix: fire the warning whenever the resulting `(external, auth_mode)` pair is strictly more permissive than the current one.
+
+##### F-P-010 — `list_active_queue_consumers` (called every 100ms) lacks a matching index
+- **Category:** Performance
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/trigger_repo.rs:1290-1303](crates/manager-core/src/trigger_repo.rs#L1290-L1303) vs [crates/manager-core/migrations/0008_triggers.sql:47-49](crates/manager-core/migrations/0008_triggers.sql#L47-L49)
+- **Summary:** Query is `WHERE t.kind='queue' AND t.enabled=TRUE` with no `app_id` filter; available index `idx_triggers_app_kind_enabled (app_id, kind) WHERE enabled = TRUE` requires an `app_id` predicate to be useful. With many apps × many trigger kinds, this query becomes a sequential scan every 100ms. Fix: add `CREATE INDEX idx_triggers_kind_enabled ON triggers(kind) WHERE enabled = TRUE`, or maintain an in-memory consumer registry refreshed by admin writes.
+
+##### F-P-011 — `RouteTable::replace_all` rebuilds the entire per-app trie on every route CRUD write
+- **Category:** Performance
+- **Severity:** Medium
+- **Location:** [crates/orchestrator-core/src/routing/table.rs:31-38](crates/orchestrator-core/src/routing/table.rs#L31-L38), [crates/manager-core/src/route_admin.rs:372-379](crates/manager-core/src/route_admin.rs#L372-L379)
+- **Summary:** Every admin route create/delete calls `refresh_table` → `routes.list_all()` → compile all rows → `replace_all`. With a thousand routes a single edit reparses every route under the writer lock. Fix: incremental update — push compiled `CompiledRoute` into the per-app slice on create, remove by id on delete.
+
+##### F-P-012 — `app_user_repo::list` cursor lacks an `(created_at, id)` tiebreaker
+- **Category:** Performance
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/app_user_repo.rs:200-225](crates/manager-core/src/app_user_repo.rs#L200-L225)
+- **Summary:** `ORDER BY created_at DESC, id DESC` but cursor is `WHERE created_at < $2` — when two users were created at the same instant, pagination can skip the second row at a page boundary or return it twice. Fix: encode `(created_at, id)` in the cursor and use `WHERE (created_at, id) < ($ts, $id)`. Same shape used elsewhere in this repo.
+
+##### F-P-013 — RhaiEngine + every SDK module registered per call
+- **Category:** Performance
+- **Severity:** Medium
+- **Location:** [crates/executor-core/src/engine.rs:167-204](crates/executor-core/src/engine.rs#L167-L204), [crates/executor-core/src/sdk/mod.rs:49-68](crates/executor-core/src/sdk/mod.rs#L49-L68)
+- **Summary:** Each `execute_ast` calls `build_engine` (new Rhai engine, every limit setter, disable-symbol, register all stdlib static modules), then `sdk::register_all` registers 12 service modules. At 32 concurrent executions on a Pi, this is real per-call overhead even with AST caching. Fix shape: pool pre-built Rhai engines with stateless modules pre-registered, reset per-call state, and only install per-call closures that need `SdkCallCx`.
+
+##### F-P-014 — `regex::*` SDK functions compile patterns on every call
+- **Category:** Performance
+- **Severity:** Medium
+- **Location:** [crates/executor-core/src/sdk/stdlib/regex.rs:23-25](crates/executor-core/src/sdk/stdlib/regex.rs#L23-L25)
+- **Summary:** `is_match`, `find`, `find_all`, `replace`, `replace_all`, `split`, `captures` all call `Regex::new(pattern)` per invocation. A script doing `regex::is_match("\\d+", x)` in a tight loop pays the compile every iteration. Fix: thread-local `LruCache<String, Arc<Regex>>` bounded to e.g. 128 entries. Regex compile dominates `is_match` on short strings.
+
+##### F-P-015 — `OutboxEventEmitter` inserts one row per matching trigger
+- **Category:** Performance
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/outbox_event_emitter.rs:88-103](crates/manager-core/src/outbox_event_emitter.rs#L88-L103)
+- **Summary:** For each matched trigger, one separate `outbox.insert` round-trip. A KV mutation matched by 5 triggers becomes 5 sequential INSERTs inside the script's hot path, each cloning the JSONB payload. Fix: extend `OutboxRepo::insert_many(rows)` and emit one multi-row `INSERT … SELECT * FROM UNNEST(...)`; bind payload once.
+
+##### F-P-016 — `app_user_session_repo::gc` `OR` chain mismatches the available index
+- **Category:** Performance
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/app_user_session_repo.rs:186-200](crates/manager-core/src/app_user_session_repo.rs#L186-L200) vs [crates/manager-core/migrations/0027_app_user_sessions.sql:34-35](crates/manager-core/migrations/0027_app_user_sessions.sql#L34-L35)
+- **Summary:** GC inner SELECT predicate is `expires_at <= NOW() OR absolute_expires_at <= NOW() OR revoked_at IS NOT NULL`. Available partial index is `(expires_at) WHERE revoked_at IS NULL` — only helps the first disjunct on non-revoked rows. The OR chain forces a sequential scan. Fix: add `CREATE INDEX … ON app_user_sessions(revoked_at) WHERE revoked_at IS NOT NULL`, and rewrite the GC as three UNION ALL subqueries (one per disjunct).
+
+##### F-Q-007 — `DispatcherError` truncates the entire error chain into `String`
+- **Category:** Code Quality
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/dispatcher.rs:957-963](crates/manager-core/src/dispatcher.rs#L957-L963) and many call sites (lines 129, 157, 176, 228, 235, 353, 365, 379, 391, 411, 453, 462, 488, 494, 545, 615, 724, 755, 779)
+- **Summary:** `DispatcherError::{Outbox, ResolveTrigger}` wrap `String`. Every `?` calls `.to_string()` on the source, killing `#[source]` introspection and the cause chain. Logs show "outbox: database error: ..." with no programmatic way to discriminate. Fix: convert to `#[from] sqlx::Error` (or structured variants) so `tracing::error!(error.cause_chain = ?err)` works.
+
+##### F-Q-008 — `HttpError::Backend` misclassifies validation errors
+- **Category:** Code Quality
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/http_service.rs:209,340,342](crates/manager-core/src/http_service.rs#L209)
+- **Summary:** `Method::from_bytes` failing on a user-supplied HTTP method gets `HttpError::Backend(format!("invalid method: {}", req.method))` — but that's user input, not a backend problem. Same for header-name / header-value validation. Misclassifying as `Backend` corrupts retry policies (operators may retry "backend" but not "invalid input"). Fix: add `HttpError::InvalidArgs(String)`.
+
+##### F-Q-009 — `dispatcher::TICK_INTERVAL` and `ASYNC_EXEC_TIMEOUT` are hard-coded; siblings are env-overridable
+- **Category:** Code Quality
+- **Severity:** Medium
+- **Location:** [crates/manager-core/src/dispatcher.rs:73,80](crates/manager-core/src/dispatcher.rs#L73)
+- **Summary:** `TICK_INTERVAL = 100ms` and `ASYNC_EXEC_TIMEOUT = 300s` are `const`. Every other timing knob in the file (cron tick, queue reclaim, retry policy) is env-overridable via `TriggerConfig::from_env()`. Operators on a constrained Pi or a busier instance can tune retries but not dispatcher cadence. Fix: promote to `TriggerConfig` with `PICLOUD_DISPATCHER_TICK_INTERVAL_MS` and `PICLOUD_DISPATCHER_ASYNC_EXEC_TIMEOUT_SEC`.
+
+##### F-Q-010 — Mutex poisoning policy inconsistent across orchestrator-core registries
+- **Category:** Code Quality
+- **Severity:** Medium
+- **Location:** [crates/orchestrator-core/src/inbox.rs:49,75](crates/orchestrator-core/src/inbox.rs#L49) (silent), [crates/orchestrator-core/src/routing/table.rs:36](crates/orchestrator-core/src/routing/table.rs#L36) (loud `expect`)
+- **Summary:** Two registries playing the same architectural role (in-memory caches behind `Arc`) handle poisoning oppositely. `RouteTable` / `AppDomainTable` `expect("route table poisoned")`; `InboxRegistry` silently swallows. Settle on one policy — the loud `expect` is correct (poisoning means a prior panic; nothing is recoverable). See also F-Q-006.
+
+##### F-Q-011 — `PostgresScriptRepoHandle` newtype hand-delegates 11 methods
+- **Category:** Code Quality
+- **Severity:** Medium
+- **Location:** [crates/picloud/src/lib.rs:622-693](crates/picloud/src/lib.rs#L622-L693)
+- **Summary:** A 70-line newtype wraps `Arc<PostgresScriptRepository>` and re-implements every `ScriptRepository` method via `self.0.method(...).await`. Comment claims it exists because the resolver wants `impl ScriptRepository` "owned." Fix: provide a blanket `impl<T: ScriptRepository + ?Sized> ScriptRepository for Arc<T>` in `manager-core`, or accept `&dyn`/`Arc<dyn>` ScriptRepository everywhere. Hand-delegation invites silent skew when the trait gains a method.
+
+##### F-Q-012 — `build_app` is ~480 lines of pure wiring
+- **Category:** Code Quality
+- **Severity:** Medium
+- **Location:** [crates/picloud/src/lib.rs:101-578](crates/picloud/src/lib.rs#L101-L578) (`#[allow(clippy::too_many_lines)]`)
+- **Summary:** Constructs ~30 `Arc<dyn ...>` handles, ~15 `*State` structs, ~12 routers, spawns 6 background tasks — all in one function with an opt-out clippy allow. Fix: extract `wire_services(pool, master_key) -> Services`, `wire_admin_states(...) -> AdminStates`, `spawn_background_tasks(...)`. Current shape makes the "field-missing" mistake in F-Q-013 easy.
+
+##### F-Q-013 — `Services::new` takes 13 positional `Arc<dyn …>` args — adding a service silently breaks all callers
+- **Category:** Code Quality
+- **Severity:** Medium
+- **Location:** [crates/shared/src/services.rs:118-148](crates/shared/src/services.rs#L118-L148), [crates/picloud/src/lib.rs:296-310](crates/picloud/src/lib.rs#L296-L310)
+- **Summary:** Constructor is `#[allow(clippy::too_many_arguments)]` and takes 13 positional handles (kv, docs, dl, events, modules, http, files, pubsub, secrets, email, users, queue, invoke). Adding workflows in v1.2 means every caller breaks silently if order is wrong. Fix: builder (`Services::builder().kv(kv).docs(docs)….build()`) or struct-literal constructor — both make field-name binding type-checked.
+
+##### F-Q-014 — Hundreds of `#[ignore]`'d integration tests with no CI hook
+- **Category:** Code Quality
+- **Severity:** Medium
+- **Location:** [crates/picloud/tests/api.rs](crates/picloud/tests/api.rs) (~60 ignored), [crates/picloud/tests/authz.rs](crates/picloud/tests/authz.rs) (~30 ignored), `crates/picloud-cli/tests/*` (~70 ignored)
+- **Summary:** Every test is `#[ignore = "needs DATABASE_URL pointing at a running Postgres"]`. Hundreds of tests don't run unless a developer explicitly runs `cargo test -- --ignored` with Postgres. No marker for "this was the test that was supposed to catch X." Fix: flip to the `schema_snapshot.rs` / `dispatcher_e2e.rs` convention (auto-skip when Postgres is absent, no `#[ignore]`), or document the CI workflow that runs them.
+
+##### F-M-001 — `idx_cron_triggers_due` index doesn't match the actual scheduler query
+- **Category:** Migration/Schema
+- **Severity:** Medium
+- **Location:** [crates/manager-core/migrations/0017_cron_triggers.sql:41](crates/manager-core/migrations/0017_cron_triggers.sql#L41), [crates/manager-core/src/cron_scheduler.rs:117-123](crates/manager-core/src/cron_scheduler.rs#L117-L123)
+- **Summary:** Index is on `(last_fired_at)` with a comment claiming it serves the scheduler. The actual query is `WHERE t.enabled = TRUE FOR UPDATE OF d SKIP LOCKED` — no `last_fired_at` predicate. The index is unused; the query is effectively a full-table scan of cron details joined to enabled triggers. Fix: either the query should filter on `last_fired_at` (to skip very-recently-fired rows), or the index should be dropped.
+
+##### F-M-002 — `email_trigger_details` encrypted-secret columns lack coupled-nullness CHECK
+- **Category:** Migration/Schema
+- **Severity:** Medium
+- **Location:** [crates/manager-core/migrations/0024_email_triggers.sql:28-32](crates/manager-core/migrations/0024_email_triggers.sql#L28-L32)
+- **Summary:** `inbound_secret_encrypted` and `inbound_secret_nonce` are each nullable independently. There is no CHECK that they be either both NULL or both NOT NULL. A bug or partial write could leave one populated and the other NULL — silently bypassing signature verification (receiver decrypts only if the encrypted column is set). Fix: `CHECK ((inbound_secret_encrypted IS NULL) = (inbound_secret_nonce IS NULL))`. Same pattern applies to `app_secrets.realtime_signing_key_encrypted/nonce` (0025).
+
+##### F-M-003 — `outbox.trigger_id` is polymorphic — no FK, orphans accumulate after route/trigger delete
+- **Category:** Migration/Schema
+- **Severity:** Medium
+- **Location:** [crates/manager-core/migrations/0009_outbox.sql:29](crates/manager-core/migrations/0009_outbox.sql#L29)
+- **Summary:** The migration notes `trigger_id` is polymorphic (`routes.id` when `source_kind='http'`, else `triggers.id`) and has no FK. Deleting a route or trigger leaves orphan outbox rows pointing at non-existent parents. Dispatcher tolerates this (rows fail dispatch and dead-letter), but a route delete + dispatcher restart can produce orphan dead-letters referencing a script that no longer matches the original route. Fix: explicit cleanup in route/trigger delete paths; consider source-kind-keyed FKs via a partial constraint or trigger.
+
+##### F-T-002 — `useEndpoint().post()` auto-fires on mount — a typo creates user records or sends emails per refresh
+- **Category:** Code Quality
+- **Severity:** Medium
+- **Location:** [clients/typescript/src/react/index.ts:73-100](clients/typescript/src/react/index.ts#L73-L100)
+- **Summary:** README says "the mutation variant (auto-fires once per mount)" — but a typical mutation is event-driven (click → POST), not fire-on-mount idempotent. Auto-firing a POST on mount creates user records, sends emails, etc. unconditionally. `useEndpoint('/api/users').post({ name })` on a typo will create a user on every refresh. Fix: refactor to `{ mutate, data, loading, error }` pattern; `mutate(body)` is event-driven, not auto-firing.

+##### F-U-004 — Five dashboard pages render light-theme fallback colors on the dark-theme app
+- **Category:** UI/UX

+- **Summary:** Styles use `var(--text-muted, #666)`, `var(--bg-secondary, #f5f5f5)`, `var(--border, #e0e0e0)`, `.error { color: #b00020; }`, `var(--color-link)` (undefined). The dashboard never defines any of these CSS custom properties, so the fallbacks are what users see. Result: light-grey text on near-white headers over the dark slate-900 page background; the dead-letters error banner is white-on-red; borders disappear on Queues. Fix: align to the explicit slate palette used by `apps/[slug]/+page.svelte`. Or, better: define CSS custom properties on a root scope.
+
+##### F-U-005 — Trigger create forms hide dispatch_mode and retry-policy knobs
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/apps/[slug]/+page.svelte:1101-1296](dashboard/src/routes/apps/[slug]/+page.svelte#L1101-L1296)
+- **Summary:** `Trigger.dispatch_mode`, `retry_max_attempts`, `retry_backoff`, `retry_base_ms` are all editable via the create API and visible in the list, but the cron/pubsub/email create forms never expose them — only queue has `retry_max_attempts`. Operators have no way to set sync vs async dispatch or backoff strategy from the UI. Fix: add an `<details>Advanced</details>` block per trigger form.
+
+##### F-U-006 — Trigger `enabled` flag never displayed; no toggle UI
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/apps/[slug]/+page.svelte:1300-1340](dashboard/src/routes/apps/[slug]/+page.svelte#L1300-L1340)
+- **Summary:** `Trigger.enabled: boolean` is on the DTO and the backend supports disabled triggers, but the trigger list never shows the state and offers no pause/resume action. Add at minimum a "• disabled" pill; ideally a toggle. If no PATCH endpoint exists, flag for backend.
+
+##### F-U-007 — Native `confirm()` and `alert()` used for route deletion
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/scripts/[id]/+page.svelte:282,287](dashboard/src/routes/scripts/[id]/+page.svelte#L282)
+- **Summary:** `removeRoute()` uses `window.confirm('Delete this route?')` and surfaces errors via `window.alert()`. The rest of the dashboard adopted `ConfirmModal` for exactly this case. The browser modal is unstyled, can't show route detail, and the alert is a dead-end. Fix: convert to a `ConfirmModal` with route details in the body and an inline error region.
+
+##### F-U-008 — Script-page "← Scripts" back-link drops out to /apps
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/scripts/[id]/+page.svelte:420](dashboard/src/routes/scripts/[id]/+page.svelte#L420)
+- **Summary:** "← Scripts" link uses `base + '/'`, which the root page redirects to `/apps`. After deleting a script the user is also bounced to `base + '/'`. The breadcrumb already resolves `appSlug`; the back-link should be `{base}/apps/{appSlug}`.
+
+##### F-U-009 — Files page exposes no upload, download, or copy-id affordance
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/apps/[slug]/files/+page.svelte:120-153](dashboard/src/routes/apps/[slug]/files/+page.svelte#L120-L153)
+- **Summary:** Listing shows name/content-type/size/created/id; only mutation is Delete. No download link, no copy-id button (the UUID is shown but unclickable), no preview, no metadata refresh. Operators must use the admin API directly. Fix: add download link per row and a copy-id button.
+
+##### F-U-010 — No instance-level configuration page surfacing `PICLOUD_*` env knobs
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** _(missing)_ `dashboard/src/routes/config/`
+- **Summary:** The platform reads ~25 `PICLOUD_*` env vars at startup (concurrency cap, session TTL, sandbox ceilings, files root + max size, SMTP timeout/TLS/port, secret max bytes, email max bytes, queue reclaim, trigger retry, HTTP allow-private, script/module cache sizes, public base URL, cookie secure). None are visible from the dashboard. Operators debugging "why is upload rejected" or "why did session expire early" have to ssh in. Fix: add a read-only `/admin/config` page using a new `GET /api/v1/admin/config` endpoint that returns non-secret current values.
+
+##### F-U-011 — Cron trigger schedule has no helper, preview, or field-count validation
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/apps/[slug]/+page.svelte:1112-1118](dashboard/src/routes/apps/[slug]/+page.svelte#L1112-L1118)
+- **Summary:** Cron input is a plain text box with placeholder `0 0 9 * * MON-FRI`. Description says "6-field cron expressions (with seconds)" but a user typing a typical 5-field crontab (`0 9 * * 1-5`) gets a confusing 422 from the server. No "next 3 fires" preview, no client-side validation. Fix: split-count check before submit, info popover listing the 6 positions, and a cron-parser preview of the next fires.
+
+##### F-U-012 — Logs viewer hard-capped at 50 rows, no pagination or filtering
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/scripts/[id]/+page.svelte:369,773-839](dashboard/src/routes/scripts/[id]/+page.svelte#L369)
+- **Summary:** `api.scripts.logs(id, { limit: 50 })` is the only call; backend supports `offset` (see [api.ts:659](dashboard/src/lib/api.ts#L659)) but there's no "load more". No filter by status (success/error/timeout/budget_exceeded), no filter by request path or log level, no time range. Operators investigating a failing script see only the most recent 50 with no way to drill back. Fix: offset pagination, status filter dropdown, and a level filter.
+
+##### F-U-013 — Queues read-only pages have no auto-refresh or refresh button
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/apps/[slug]/queues/+page.svelte:56-91](dashboard/src/routes/apps/[slug]/queues/+page.svelte#L56-L91), [dashboard/src/routes/apps/[slug]/queues/[name]/+page.svelte:50-90](dashboard/src/routes/apps/[slug]/queues/[name]/+page.svelte#L50-L90)
+- **Summary:** Queue depths change continuously; the page shows a page-load snapshot with no way to update without a hard refresh. Dead-letters has a Refresh button; queues doesn't. Fix: add a Refresh button; auto-refresh-every-5s toggle would make this page useful for live monitoring.
+
+##### F-U-014 — Email-inbound webhook URL uses `window.location.origin` — wrong under reverse proxy
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/apps/[slug]/+page.svelte:246-248](dashboard/src/routes/apps/[slug]/+page.svelte#L246-L248)
+- **Summary:** `emailInboundUrl()` builds `${window.location.origin}/api/v1/email-inbound/...`. If the admin browses via an internal LAN address but the public webhook URL is on a different host, the dashboard hands the operator the wrong URL. `VersionInfo.public_base_url` already exists for exactly this case. Fix: use `version.public_base_url` instead of `window.location.origin`.
+
+##### F-U-015 — No session-expiry warning; silent 401 redirect drops in-flight form state
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/lib/api.ts:438-446](dashboard/src/lib/api.ts#L438-L446)
+- **Summary:** On any 401 the fetch wrapper immediately calls `clearSession()` and `goto('/login')`. A user mid-edit on a long Rhai script loses the entire scratch. No warning before expiry, no interstitial showing lost state, no draft auto-save. Fix: session-warning toast ~5min before TTL; localStorage-backed source drafts; "your session expired, sign in again" interstitial preserving form state.
+
+##### F-U-016 — Several modals lack focus trap — Tab moves focus to background elements
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/lib/ConfirmModal.svelte:100-156](dashboard/src/lib/ConfirmModal.svelte#L100-L156), [dashboard/src/routes/users/+page.svelte:402-476](dashboard/src/routes/users/+page.svelte#L402-L476)
+- **Summary:** `ConfirmModal` focuses the first input on mount and listens for Escape but doesn't trap Tab. Keyboard users can Tab out of the modal into the underlying page. Fix: implement focus trap (via `inert` on the rest of the document, or a Tab-bound key handler).
+
+##### F-U-017 — Users tables grid columns overflow below ~700px viewport
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/users/+page.svelte:727-734](dashboard/src/routes/users/+page.svelte#L727-L734), [dashboard/src/routes/profile/+page.svelte:669-677](dashboard/src/routes/profile/+page.svelte#L669-L677)
+- **Summary:** Both tables use 7- and 8-column CSS grids with no `@media` rule for mobile. Columns squash and the search input pushes header controls off-screen on narrow viewports. Fix: switch to card layout below `min-width: 600px`, or horizontal scroll with sticky first column.
+
+##### F-U-018 — Dashboard can't create instance admins in the "owner" role
+- **Category:** UI/UX
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/users/+page.svelte:452-462](dashboard/src/routes/users/+page.svelte#L452-L462)
+- **Summary:** Invite-user modal offers radios "admin" and "member" only. Owner can be granted only by editing an existing user. This is intentional friction (prevents the first-owner footgun) but is asymmetric with `editRoleOptions` (line 111) where owners can assign owner directly. Document the distinction visibly above the role group, or expose "Owner" for the bootstrapping case.
+
+#### Low
+
+- **F-S-015** — `users::login` requires `AppUsersWrite` so authenticated viewer-role scripts can't authenticate users — sharp edge for "login form on an authed admin page". [users_service.rs:478-485](crates/manager-core/src/users_service.rs#L478-L485) — Low
+- **F-S-016** — Dispatcher `trigger_depth > max` vs invoke SDK `cx.trigger_depth + 1 > max` differ by one level; align the boundary semantics and add a unit test. [dispatcher.rs:342](crates/manager-core/src/dispatcher.rs#L342), [invoke.rs:141](crates/executor-core/src/sdk/invoke.rs#L141)
+- **F-S-017** — `SmtpConfig` derives `Debug` with raw `password: String` — accidental `tracing::debug!(?cfg)` leaks. [email_service.rs:88-97](crates/manager-core/src/email_service.rs#L88-L97). Hand-implement `Debug` with redaction.
+- **F-S-018** — `OutboxEventEmitter` log-and-ignore on emit failure: triggers can silently miss events if the outbox insert fails after the primary write. [kv_service.rs:114-130](crates/manager-core/src/kv_service.rs#L114-L130), [docs_service.rs:122-138](crates/manager-core/src/docs_service.rs#L122-L138), [files_service.rs:74-102](crates/manager-core/src/files_service.rs#L74-L102). Bump a metric on emit failure; long-term make primary + outbox a single tx.
+- **F-S-019** — `retry::run` allows cumulative sleep far exceeding the wall-clock timeout, tying up a gate permit. [retry.rs:189-222](crates/executor-core/src/sdk/retry.rs#L189-L222). Cap cumulative sleep inside `retry::run`.
+- **F-S-020** — `request_password_reset` email-send clamping accumulates dead reset tokens when SMTP misconfigured. Mark the just-inserted row consumed when `email.send` returns non-NotConfigured failures. [users_service.rs:678-690](crates/manager-core/src/users_service.rs#L678-L690)
+- **F-S-021** — Bearer token in `Set-Cookie` not validated against cookie-octet alphabet — if the token format ever changes, header injection becomes possible. [auth_api.rs:207-223](crates/manager-core/src/auth_api.rs#L207-L223). Guard with `[A-Za-z0-9_-]+`.
+- **F-S-022** — `attach_principal_if_present` swallows DB errors as anonymous — a transient DB blip strips authed callers and converts authed writes into anonymous writes that skip the capability gate (e.g. on `secrets_service`). [auth_middleware.rs:119-130](crates/manager-core/src/auth_middleware.rs#L119-L130)
+- **F-S-023** — `users::login` cross-app belt-and-suspenders check is unreachable in practice. Assert the invariant at the repo boundary instead. [users_service.rs:478-514](crates/manager-core/src/users_service.rs#L478-L514)
+- **F-S-024** — `PICLOUD_COOKIE_SECURE` env-var parsing is inverted-boolean readability. Replace with explicit `is_truthy` parse identical to crypto.rs. [auth_api.rs:212-218](crates/manager-core/src/auth_api.rs#L212-L218)
+- **F-S-025** — Realtime signing key plaintext lingers in `Vec<u8>` allocations without zeroize; heap dumps can leak. Use `Zeroizing<Vec<u8>>` for the realtime signing key and `ZeroizeOnDrop` for `MasterKey`. [app_secrets_repo.rs:78-91](crates/manager-core/src/app_secrets_repo.rs#L78-L91), [realtime_authority.rs:34](crates/manager-core/src/realtime_authority.rs#L34), [shared/crypto.rs:117](crates/shared/src/crypto.rs#L117)
+- **F-S-026** — Inbound-email decrypt failure → 401 conflates DB blip with bad signature; provider retries hammer the endpoint indefinitely. [email_inbound_api.rs:149-166](crates/manager-core/src/email_inbound_api.rs#L149-L166). Surface decryption failure as a logged 500.
+- **F-S-027** — Migration 0006 backfills every Phase-3a admin to `'owner'` — documented but permissive. Future audits may surface unexpected owner sprawl. [0006_users_authz.sql:24-30](crates/manager-core/migrations/0006_users_authz.sql#L24-L30)
+- **F-S-028** — API-key prefix collisions force the middleware to Argon2-verify every candidate; cap the candidate set at a small constant (e.g. 16). [auth_middleware.rs:198-211](crates/manager-core/src/auth_middleware.rs#L198-L211)
+- **F-S-029** — `admin_reset_password_token` returns raw token in JSON without rate limit. Mint a new token doesn't invalidate prior unconsumed tokens. [users_service.rs:902-927](crates/manager-core/src/users_service.rs#L902-L927)
+- **F-S-030** — `GeneratedSession`/`GeneratedAccept`/`GeneratedToken` derive `Debug` with raw tokens — same footgun as F-S-017. [shared/users.rs:89-102](crates/shared/src/users.rs#L89-L102), [auth.rs:72](crates/manager-core/src/auth.rs#L72)
+- **F-S-031** — `auth_middleware::touch` failure becomes 500, blocking authed requests on transient DB blips. Fail-soft (log + continue with existing expiry). [auth_middleware.rs:170-176](crates/manager-core/src/auth_middleware.rs#L170-L176)
+- **F-S-032** — Cookie `SameSite=Lax` is not exploitable today (admin POSTs accept JSON only), but adding a `Form<...>` extractor would make it CSRF-able. Switch admin cookie to `SameSite=Strict`. [auth_api.rs:175,220-223](crates/manager-core/src/auth_api.rs#L175)
+- **F-P-017** — `execute_by_id` clones request body, headers, and path before executing — wasteful on large bodies. Serialize logged shape from `&req` after a Result branch. [orchestrator-core/src/api.rs:117-159](crates/orchestrator-core/src/api.rs#L117-L159)
+- **F-P-018** — Sync HTTP path serializes body twice and clones a 3rd time for audit log. [orchestrator-core/src/api.rs:363-373](crates/orchestrator-core/src/api.rs#L363-L373)
+- **F-P-019** — `realtime_authority::signing_key` clones a `Vec<u8>` under `Mutex` on every cache hit. Use `Arc<[u8]>` so clone is a refcount bump. [realtime_authority.rs:56-72](crates/manager-core/src/realtime_authority.rs#L56-L72)
+- **F-P-020** — Files orphan sweep walks the entire blob tree synchronously every 6h. Skip subtrees by mtime, or track temp files in a `files_pending_tmp` table. [files_sweep.rs:75-111](crates/manager-core/src/files_sweep.rs#L75-L111)
+- **F-P-021** — `dispatcher.handle_failure` decodes payload JSON 3× per failure. Decode once at top of `handle_failure`. [dispatcher.rs:741-848](crates/manager-core/src/dispatcher.rs#L741-L848)
+- **F-P-022** — `InProcessBroadcaster::publish` allocates a `String` from the `&str` topic per publish for the lookup key, even when no subscriber exists. Use a borrowed equivalent (`raw_entry_mut`). [orchestrator-core/src/realtime.rs:107-117](crates/orchestrator-core/src/realtime.rs#L107-L117)
+- **F-P-023** — `dead_letters_api` `unresolved_count` is `COUNT(*)` per dashboard load. Partial index covers it today; cap at 100 with a "100+" UI state. [dead_letter_repo.rs:172-181](crates/manager-core/src/dead_letter_repo.rs#L172-L181)
+- **F-P-024** — Inline `block_on` for `signing_key` lookup in the realtime hot path on cold cache — fleet of reconnecting subscribers hits Postgres N times. Warm cache for active apps at startup. [realtime_authority.rs:99-102](crates/manager-core/src/realtime_authority.rs#L99-L102)
+- **F-P-025** — `attach_principal_if_present` middleware applied twice on overlapping routers (`data_plane_routed` + `user_routes`). Confirm no double-Argon2. [picloud/src/lib.rs:546-553](crates/picloud/src/lib.rs#L546-L553)
+- **F-Q-015** — `pubsub_service::publish_durable` spawns a task only to immediately await its `JoinHandle` — accomplishes nothing the inline `.await` wouldn't. [pubsub_service.rs:193-198](crates/manager-core/src/pubsub_service.rs#L193-L198)
+- **F-Q-016** — `KvError::from(KvRepoError)` does `Backend(e.to_string())` for any repo error; files_service has the right shape (pattern-match and promote). Adopt uniformly. [kv_service.rs:74-78](crates/manager-core/src/kv_service.rs#L74-L78), [files_service.rs:111-119](crates/manager-core/src/files_service.rs#L111-L119)
+- **F-Q-017** — `kv_service.rs` and `docs_service.rs` inline emit-and-log boilerplate 17 lines × 2 callsites; `files_service` / `users_service` already extract it. Apply the `emit` helper pattern. [kv_service.rs:111-130](crates/manager-core/src/kv_service.rs#L111-L130), [docs_service.rs:122-138](crates/manager-core/src/docs_service.rs#L122-L138)
+- **F-Q-018** — `auth_api::login` has a stale `.unwrap()` after the contract has been narrowed; future refactor of the predicate ordering can re-enable the panic. Use `let Some(user_id) = user_id else { … };`. [auth_api.rs:102](crates/manager-core/src/auth_api.rs#L102)
+- **F-Q-019** — SDK trait methods in `shared/` lack per-method rustdoc on most public surfaces. [shared/src/{kv,docs,queue,files,secrets,email,pubsub,users}.rs](crates/shared/src/)
+- **F-Q-020** — Several tests use `assert!(... .is_ok())` instead of asserting on the value — auth, realtime_authority, http_service especially. [client.rs:408](crates/orchestrator-core/src/client.rs#L408), [http_service.rs:774](crates/manager-core/src/http_service.rs#L774), [auth.rs:186](crates/manager-core/src/auth.rs#L186), [realtime_authority.rs:251](crates/manager-core/src/realtime_authority.rs#L251)
+- **F-Q-021** — `gc::SWEEP_INTERVAL` (weekly) and 5000-row batch hardcoded; retention is env-overridable but cadence isn't. Promote to `TriggerConfig`. [gc.rs:25,30](crates/manager-core/src/gc.rs#L25)
+- **F-Q-022** — `SmtpConfig::from_env` uses bare literal `.unwrap_or(30)` for default timeout. Name it `DEFAULT_SMTP_TIMEOUT_SECS`. [email_service.rs:128](crates/manager-core/src/email_service.rs#L128)
+- **F-M-004** — Redundant or under-targeted indexes: `secrets (app_id)` duplicates PK leftmost prefix; `idx_kv_entries_app_collection` duplicates PK; `idx_queue_trigger_details_queue_name` lacks `app_id`; `idx_triggers_app_pubsub_enabled` duplicates broader `idx_triggers_app_kind_enabled`. Each costs write amplification without enabling new plans. [0007_kv.sql:28](crates/manager-core/migrations/0007_kv.sql#L28), [0020_pubsub_triggers.sql:32](crates/manager-core/migrations/0020_pubsub_triggers.sql#L32), [0023_secrets.sql:24](crates/manager-core/migrations/0023_secrets.sql#L24), [0035_queue_triggers.sql:40](crates/manager-core/migrations/0035_queue_triggers.sql#L40)
+- **F-M-005** — `triggers.retry_max_attempts`/`retry_base_ms` and `queue_messages.max_attempts`/`attempt` have no CHECK against negative or absurd values. Apply the `scripts.timeout_seconds CHECK (> 0 AND <= 300)` discipline. [0008_triggers.sql:35,38](crates/manager-core/migrations/0008_triggers.sql#L35), [0034_queue_messages.sql:28-29](crates/manager-core/migrations/0034_queue_messages.sql#L28-L29)
+- **F-M-006** — `dead_letters.resolution` is NULL-able with no coupled-with-`resolved_at` CHECK. Same pattern as F-M-002. [0010_dead_letters.sql:37-40](crates/manager-core/migrations/0010_dead_letters.sql#L37-L40)
+- **F-M-007** — `routes_unique_binding_idx` uses `COALESCE(method, '')` allowing ambiguous binding (an empty-string method conflicts with a NULL method). Add `CHECK method IS NULL OR method IN ('GET','POST',…)`. [0005_apps.sql:100](crates/manager-core/migrations/0005_apps.sql#L100)
+- **F-T-003** — `subscribeTopic` 401 refresh path recurses without backoff. If `onTokenExpired` returns a stale token, unbounded recursion. Track `consecutive401Count`. [subscribe.ts:63-75](clients/typescript/src/subscribe.ts#L63-L75)
+- **F-T-004** — `subscribeTopic` resets `attempt = 0` after a successful connect, but a stream that errors immediately after one byte means the next reconnect is `base * 2^0` (no backoff) — hot reconnect loop possible. Gate the reset on receiving the first event or an uptime threshold. [subscribe.ts:82-96](clients/typescript/src/subscribe.ts#L82-L96)
+- **F-T-005** — `useTopic` excludes `opts` from deps — a caller changing `validate: zSchemaA` to `zSchemaB` for the same topic won't take effect. Document that `opts` is captured once per topic. [react/index.ts:39-55](clients/typescript/src/react/index.ts#L39-L55)
+- **F-T-006** — `parseBody` swallows JSON parse errors and silently falls through to text; the caller's `validate.parse` then receives raw text and throws a confusing "expected object". [endpoint.ts:84-95](clients/typescript/src/endpoint.ts#L84-L95)
+- **F-T-007** — `joinUrl` doesn't normalize repeated slashes (`https://x/v1//users` survives). Strip multiple consecutive `/` in the path portion. [endpoint.ts:102-106](clients/typescript/src/endpoint.ts#L102-L106)
+- **F-T-008** — `tsup.config.ts` externals don't include `react/jsx-runtime` — if anyone uses JSX syntax, the build bundles a copy. Pre-emptive add. [tsup.config.ts:17](clients/typescript/tsup.config.ts#L17)
+- **F-T-009** — `AuthClient` token storage is in-memory only; SSR and persistence-across-refresh aren't documented. Add a README section on the `onToken` callback + storage trade-off. [auth.ts:26](clients/typescript/src/auth.ts#L26)
+- **F-T-010** — `AuthClient.login` hardcoded to `{ email, password }` — overload with arbitrary credentials object would suit the hybrid-model intent. [auth.ts:39-48](clients/typescript/src/auth.ts#L39-L48)
+- **F-U-019** — Email-trigger inbound webhook URL has no copy button (compare API-key reveal pattern with clipboard support). [+page.svelte:1321](dashboard/src/routes/apps/[slug]/+page.svelte#L1321)

+- **F-U-021** — Several pages override `.container { max-width }` inside a layout that already caps at 64rem — the override is silently ignored, and dead-letters' 8-column table overflows on narrow viewports.

+- **F-U-025** — Apps list refetches dead-letter counts in N+1 (one per app) on every mount. Backend endpoint to batch counts would be O(1). [apps/+page.svelte:19-33](dashboard/src/routes/apps/+page.svelte#L19-L33)
+- **F-U-026** — Login form doesn't reset password on failed attempt — typo persists into next try. Either clear the password or add a "show password" toggle. [login/+page.svelte:24-36](dashboard/src/routes/login/+page.svelte#L24-L36)
+- **F-U-027** — App-user create form has no password strength meter or visibility toggle. The instance Users page uses `generatePassword(16)` + reveal-once — much safer for the admin-bootstraps-user flow.

+
+## Methodology notes
+
+- **Subagents:** 6 parallel `general-purpose` agents — Security data-plane, Security auth/secrets, Performance, Code Quality (Rust crates), UI/UX (dashboard), Migration/Schema + TypeScript client. Orchestrator (this conversation) read the project docs and verified the highest-severity findings against actual file/line state before writing the report.
+- **Wall-clock:** Single message of parallel agent dispatch + post-processing; agents took 4–22 minutes each.
+- **Verification:** F-Q-001 (manager-core cross-crate behavior import) confirmed via `grep`. F-T-001 (Rules of Hooks) confirmed by reading [clients/typescript/src/react/index.ts](clients/typescript/src/react/index.ts). F-P-001 (users::list N+1) confirmed at [users_service.rs:466-471](crates/manager-core/src/users_service.rs#L466-L471). F-P-003 (pool=10) confirmed at [picloud/src/lib.rs:583-588](crates/picloud/src/lib.rs#L583-L588). F-S-001 (unbounded queue payload) confirmed at [queue_service.rs:33-92](crates/manager-core/src/queue_service.rs#L33-L92). F-U-002 (queue drilldown 404) confirmed via grep against the routes tree.
+- **Coverage gaps:**
+  - The `dashboard/tests/e2e/` Playwright suite was out of scope per the brief (149 known errors from missing `@playwright/test`).
+  - The `clients/typescript/` package got a shallower pass than the Rust crates — appropriate since it's a deliberately minimal surface per v1.1.6 hybrid-model decision.
+  - The orchestrator did not run the test suites; subagent line-number citations are accurate at audit time but may drift if files change.
+  - SQL query plans were not measured — performance findings are static-analysis based, citing the predicate-vs-index mismatch shape rather than EXPLAIN output.
+  - Caddyfile + docker-compose configurations not audited (the brief focused on application code).
+  - `crates/picloud-cli/` got a light pass (mainly the `#[ignore]`'d tests count).
+- **Notes to next reviewer:**
+  - The Critical (F-Q-001) is structural and load-bearing for the cluster-mode roadmap (v1.3+) — addressing it is a v1.2+ release in its own right, not a v1.1.10 patch.
+  - The High-severity performance findings (F-P-001..F-P-009) cluster around two themes: (1) auth middleware doing Argon2id on the async runtime per request, (2) N+1 / OFFSET / COUNT(*) anti-patterns that an instance with real traffic will feel immediately. A focused "perf clean-up" release (call it v1.1.10) could land 6–8 of these as a single bundled PR.
+  - F-S-001 (unbounded payloads) is a one-PR fix that hardens four services at once; consider doing it before any external preview.
+  - The dashboard CSS-variable issue (F-U-004) is one global theme-token fix that closes 5+ pages worth of light-on-dark rendering.
+  - The TypeScript client `useEndpoint` (F-T-001) is a public API correctness bug — fix or undocument before any 1.x stability claim on the client.

 # PiCloud Changelog
 
+## v1.1.9 — Durable Queues & Function Composition (unreleased)
+
+Per-app durable queues + same-app function composition + caller-
+controlled retries. The final v1.1.x release before the v1.2 phase
+milestone. **No upgrade-order constraint** — pure additive surface,
+no destructive migrations.
+
+### Added — `queue::*` SDK (durable per-app named queues)
+
+- **`queue::enqueue(name, message)` / `queue::enqueue(name, message, opts)`**
+  — write one message onto a per-app named queue. `opts` is a Map
+  with `delay_ms` (defer delivery until `NOW() + delay`) and
+  `max_attempts` (clamped to `[1, 20]`; default 3). Message is any
+  JSON-serializable value — Maps, Arrays, scalars, and Blobs (which
+  base64-encode at any depth, mirroring `pubsub::publish_durable`).
+  FnPtr / closures are rejected at the bridge.
+- **`queue::depth(name)` / `queue::depth_pending(name)`** — read-only
+  inspection. `depth` is `COUNT(*)`; `depth_pending` filters to
+  `claim_token IS NULL AND (deliver_after IS NULL OR deliver_after <= NOW())`.
+- Identity tuple is `(app_id, queue_name)`. Queue names are implicit
+  — no queue registry table, no separate "create queue" ceremony. A
+  queue exists once the first message is enqueued under that name.
+- No `peek` / `dequeue` / `purge` script-side surface. Consumers are
+  triggers; exposing manual dequeue would force the platform to
+  surface visibility-timeout semantics into script-land.
+- New capability `AppQueueEnqueue(AppId)` (script:write scope, editor+).
+
+### Added — `queue:receive` trigger kind
+
+- **Exactly one consumer per `(app_id, queue_name)`** — enforced via
+  `pg_advisory_xact_lock(hash(app_id || queue_name))` + a SELECT-then-
+  INSERT in one transaction (a partial unique index can't span the
+  parent's `app_id` from the detail table). The second create returns
+  `422 Invalid` with the message `queue 'X' already has a consumer
+  trigger; remove the existing one first`.
+- Per-trigger `visibility_timeout_secs` (clamped `[5, 3600]`; default
+  via `PICLOUD_QUEUE_DEFAULT_VISIBILITY_TIMEOUT_SECS`). The dispatcher
+  treats this as the lease window; a handler that holds the claim
+  past this point loses it to the periodic reclaim task.
+- Retry policy lives on the parent `triggers` row (the same
+  `retry_max_attempts` / `retry_backoff` / `retry_base_ms` every
+  other trigger kind reads); no duplication on the detail row.
+- Surfaced to handler scripts as `ctx.event.queue` —
+  `{ queue_name, message, enqueued_at, attempt, message_id }` — plus
+  `ctx.event.source = "queue"` and `ctx.event.op = "receive"`.
+- Trigger executes as the principal that **registered** it (matches
+  design notes §4 — every trigger kind does this).
+
+### Added — Dispatcher queue arm + visibility-timeout reclaim task
+
+- The queue table IS the outbox for queue semantics. The dispatcher
+  doesn't double-buffer through `outbox`; it claims directly from
+  `queue_messages` via the single-round-trip
+  `UPDATE … WHERE id = (SELECT id … FOR UPDATE SKIP LOCKED LIMIT 1)
+   RETURNING …`. `SKIP LOCKED` keeps concurrent dispatchers (cluster
+  mode v1.3+) safe.
+- Per tick (every 100ms), interleaved with the existing outbox arm:
+  list every enabled `queue:receive` consumer and try one claim each.
+  Bounded by the registered-consumer count, so one busy queue can't
+  starve the rest.
+- **Auto-ack**: handler returns successfully → `DELETE FROM queue_messages
+   WHERE id = $1 AND claim_token = $2`. The token in the WHERE is the
+  leasing guarantee.
+- **Auto-nack**: handler throws → if `attempt < max_attempts`, clear
+  the claim and set `deliver_after = NOW() + compute_backoff(...)`;
+  else, write a `dead_letters` row (the existing `fan_out_dead_letter`
+  path then fires registered `dead_letter` triggers off it) and delete
+  the queue row, in one transaction.
+- **Visibility-timeout reclaim**: a separate `tokio::spawn` task ticks
+  every `PICLOUD_QUEUE_RECLAIM_INTERVAL_MS` (default 30000) and clears
+  claims older than the per-queue `visibility_timeout_secs`. A crashed
+  consumer (or one whose handler hung past the visibility window) thus
+  loses its lease and the message becomes claimable again.
+
+### Added — `invoke()` + `invoke_async()` (same-app function composition)
+
+- **`invoke(target, args)`** — sync, returns the callee's response
+  body as a Rhai Dynamic. `target` is a string (path → route trie,
+  UUID → `ScriptId`, else → `(app_id, name)` lookup). Same engine
+  instance and `Services` are reused; only the per-call `SdkCallCx`
+  changes (callee gets `trigger_depth + 1` and a fresh `execution_id`,
+  inherits the caller's principal and `root_execution_id`).
+- **`invoke_async(target, args)`** — fire-and-forget. Writes an
+  `OutboxSourceKind::Invoke` row the dispatcher fires once (no retry
+  loop — callers who want retries wrap in `retry::run`). Returns the
+  new `ExecutionId` as a string for caller tracking.
+- **Cross-app invokes are rejected** at the `InvokeService::resolve`
+  layer with `InvokeError::CrossApp` ("invoke: target script belongs
+  to a different app"). v1.1.x maintains strict isolation; cross-app
+  sharing arrives in v1.3+.
+- **Depth-bound**: `cx.trigger_depth + 1 > limits.trigger_depth_max`
+  throws "invoke: depth limit exceeded (max N)" — shared with the
+  trigger fan-out cap so a misbehaving recursive script can't blow
+  the stack.
+- FnPtr / closures in `args` are rejected (closures don't survive
+  re-entry into a fresh `SdkCallCx`).
+
+### Added — `retry::*` SDK (caller-controlled retry)
+
+- **`retry::policy(opts)`** — constructs a `Policy` value (custom Rhai
+  type). Validates + clamps: `max_attempts ∈ [1, 20]`,
+  `base_ms ∈ [1, 60_000]`, `jitter_pct ∈ [0, 100]`,
+  `backoff ∈ {"exponential" | "linear" | "constant"}`.
+- **`retry::run(policy, closure)`** — calls `closure()`; on throw,
+  sleeps per the policy and re-invokes; after `max_attempts`
+  exhausted, throws the last error. Sleeps via `tokio::time::sleep`
+  through `TokioHandle::block_on` — the bridge is already inside the
+  caller's `spawn_blocking` thread.
+- **`retry::on_codes(policy, codes_array)`** — returns a new policy
+  with an error-string filter. When non-empty, only throws containing
+  one of the codes retry; others surface immediately.
+- **NOTE on the brief deviation**: the brief asked for `retry::with`,
+  but both `with` AND `call` are Rhai reserved keywords (rejected at
+  the parser, before registration could matter). Shipped as
+  `retry::run(policy, closure)` instead. Documented in HANDBACK §7.
+
+### Added — Admin HTTP endpoints
+
+- `POST /api/v1/admin/apps/{id}/triggers/queue` — create a
+  `queue:receive` trigger. Body:
+  `{ script_id, queue_name, visibility_timeout_secs?, dispatch_mode?,
+     retry_max_attempts?, retry_backoff?, retry_base_ms? }`.
+  Capability: `AppManageTriggers`.
+- `GET /api/v1/admin/apps/{id}/queues` — list every distinct queue
+  name in the app with `(total, pending, claimed)` counts.
+  Capability: `AppLogRead`.
+- `GET /api/v1/admin/apps/{id}/queues/{queue_name}` — drill-down:
+  stats + registered consumer trigger (if any). Capability:
+  `AppLogRead`.
+- No mutating queue endpoints (purge / requeue / delete-message stays
+  at v1.2).
+
+### Added — Dashboard (v0.15.0)
+
+- New `/apps/{slug}/queues` read-only list view (queue name + counts +
+  drilldown link) and `/apps/{slug}/queues/{name}` drill-down (depth +
+  registered consumer + visibility timeout + last_fired_at).
+- "Queues" link added to the app-level nav between Files and Dead
+  letters.
+- Triggers tab gains a "Queue:receive trigger (v1.1.9)" form alongside
+  cron / pubsub / email. Trigger list renders queue triggers with the
+  queue name + visibility timeout + last_fired_at.
+- TypeScript types: `TriggerKind` gains `'queue'`; `TriggerDetails`
+  gains the `Queue` variant. `CreateQueueTriggerInput`,
+  `QueueSummary`, `QueueConsumer`, `QueueDetail` exported.
+
+### Changed
+
+- `Services::new` signature gains `queue: Arc<dyn QueueService>` and
+  `invoke: Arc<dyn InvokeService>` positionally after `users` (mirrors
+  v1.1.8's positional append of `users`). `with_noop_services` updated.
+- `Limits` (`crates/executor-core/src/sandbox.rs`) gains
+  `trigger_depth_max: u32` (default 8). The picloud binary syncs it
+  from `TriggerConfig::from_env().max_trigger_depth` so the
+  dispatcher's trigger-depth cap and the invoke depth-bound stay
+  aligned (env var: `PICLOUD_MAX_TRIGGER_DEPTH`).
+- `Engine` gains `set_self_weak(Weak<Engine>)` + `self_arc()`. The
+  picloud binary calls `engine.set_self_weak(Arc::downgrade(&engine))`
+  right after construction so the invoke bridge can re-enter the
+  engine synchronously. `Weak` so the Arc-cycle stays loose.
+- `register_all` gains two parameters: `limits: Limits` and
+  `self_engine: Option<Arc<Engine>>`. The invoke bridge surfaces a
+  clear error if `self_engine` is `None` (only in harnesses that don't
+  wire it).
+- `OutboxSourceKind` gains `Invoke`; `TriggerKind` gains `Queue`;
+  `TriggerDetails` gains the `Queue` variant; `TriggerEvent` gains the
+  `Queue` variant with `source = "queue"` discriminant.
+- `ScriptRepository` gains `get_by_name(app_id, name)` for the
+  `invoke()` name resolution path.
+- SDK schema 1.9 → 1.10.
+
+### Migrations
+
+- `0034_queue_messages.sql` — the `queue_messages` table with three
+  indexes: a partial `(app_id, queue_name, enqueued_at) WHERE
+  claim_token IS NULL` for the dispatch hot path, a `(app_id,
+  queue_name)` for the depth queries, and a partial `(claimed_at)
+  WHERE claim_token IS NOT NULL` for the reclaim scan.
+- `0035_queue_triggers.sql` — widens `triggers.kind` to admit
+  `'queue'`, widens `outbox.source_kind` to admit `'invoke'`, adds the
+  `queue_trigger_details` table.
+
+### F1–F5 follow-ups (carry-forward from v1.1.8)
+
+- **F1 — integration test density**: four new DB-gated test binaries
+  (`crates/picloud/tests/queue_e2e.rs` ×4, `…/invoke_e2e.rs` ×4,
+  `…/retry_e2e.rs` ×3, `crates/manager-core/tests/migration_queue_messages.rs`
+  ×4) + 50+ net new inline unit tests. All skip cleanly when
+  `DATABASE_URL` is unset; all pass against the docker-compose
+  postgres on `localhost:15432`.
+- **F2 — schema snapshot re-blessed** via
+  `BLESS=1 cargo test -p picloud-manager-core --test schema_snapshot
+   -- --include-ignored`. Delta matches the plan exactly (no unrelated

+    visibility timeout fallback when the trigger create request omits

+- `@picloud/client` unchanged — no client-library work this release.

+## v1.1.8 — User Management (unreleased)
+
+Per-app data-plane user management — a `users::*` SDK for scripts
+plus an admin HTTP surface and dashboard tab — together with three
+load-bearing follow-ups from v1.1.7 (dropping the plaintext realtime
+signing-key column, `--all-targets` clippy discipline, and adding a
+session-based realtime SSE auth mode).
+
+**UPGRADE PATH IS LOAD-BEARING.** v1.1.8 requires v1.1.7 to have
+been applied first. Operators upgrading directly from v1.1.6 or
+earlier MUST apply v1.1.7 (and let its startup encryption sweep
+complete) before applying v1.1.8 — migration 0032's guard refuses
+to drop the plaintext `realtime_signing_key` column while any row
+still needs encryption.
+
+### Added — `users::*` SDK (data-plane user management)
+
+- **`users::create(#{...})` / `users::get(id)` / `users::find_by_email(...)`
+  / `users::update(id, #{...})` / `users::delete(id)` /
+  `users::list(#{ "$limit", cursor })`** — CRUD on per-app end-users
+  (distinct from the control-plane `admin_users` table). Identity tuple
+  is `(app_id, user_id)`; uniqueness is on `(app_id, lower(email))` so
+  the same email can exist across two apps but not twice within one.
+  Password hash is Argon2id PHC (same algorithm as `admin_users`);
+  the public AppUser record never carries the hash.
+- **`users::login(email, password)`** returns a session token string,
+  or `()` on bad credentials. The bad-email and bad-password branches
+  share wall-clock cost via a timing-flat dummy Argon2id verify on
+  email miss. **Required for security**, not polish.
+- **`users::verify(token)`** returns the user on success (bumping the
+  sliding TTL), `()` on missing / expired / revoked / cross-app.
+- **`users::logout(token)`** revokes the session row.
+- `migrations/0026_app_users.sql` + `0027_app_user_sessions.sql`.
+
+### Added — Sessions
+
+- `app_user_sessions` table with SHA-256 token hash, sliding TTL
+  (`PICLOUD_APP_USER_SESSION_TTL_HOURS`, default 24h), hard cap
+  (`PICLOUD_APP_USER_SESSION_ABSOLUTE_HOURS`, default 720h = 30d),
+  and explicit `revoked_at` for logout / admin revoke-all / password-
+  reset side-effects. Lookups reject revoked/expired rows
+  immediately, before the weekly GC sweep runs.
+
+### Added — Email verification
+
+- **`users::send_verification_email(user_id, #{ link_base, from,
+  subject, body_template })`** mints a 32-byte token, stores its
+  SHA-256 in `app_user_email_verifications`, and dispatches via
+  `email::send` with `{link}` in the body substituted for
+  `link_base?token=<raw>`. `EmailError::NotConfigured` propagates as
+  `UsersError::EmailNotConfigured` so scripts already handling the
+  v1.1.7 email-disabled mode don't need new branches.
+- **`users::verify_email(token)`** atomically consumes the one-shot
+  token, sets `email_verified_at = NOW()`, emits
+  `users::email_verified`.
+- `migrations/0028_app_user_email_verifications.sql`.
+
+### Added — Password reset
+
+- **`users::request_password_reset(email, #{ template })`** returns
+  `Ok(())` regardless of whether the email matched — no
+  existence-leak signal in script-land. Email-not-configured does
+  surface (operators need to know); other email failures are silently
+  swallowed and logged server-side.
+- **`users::complete_password_reset(token, new_password)`** atomically
+  consumes the token, updates the Argon2id hash, and **revokes every
+  active session** for the user (stale tokens shouldn't ride out the
+  reset). TTL `PICLOUD_APP_USER_PASSWORD_RESET_TTL_HOURS` (default 1h).
+- `migrations/0029_app_user_password_resets.sql`.
+
+### Added — Invitations
+
+- **`users::invite(email, #{ template?, display_name?, roles? })`**
+  gated on `AppUsersAdmin`. Omitting the template skips the email
+  send so an admin can issue invitations for out-of-band delivery.
+- **`users::accept_invite(token, password, display_name?)`** atomically
+  consumes the invitation, creates the user with pre-staged roles
+  applied, and mints a fresh session — caller can return both the
+  user and the session token in one round trip. TTL
+  `PICLOUD_APP_USER_INVITATION_TTL_DAYS` (default 7d).
+- `migrations/0030_app_user_invitations.sql`.
+
+### Added — Per-app roles
+
+- **`users::add_role(id, role)` / `users::remove_role(id, role)` /
+  `users::has_role(id, role)`** — string-tagged, per-app. The script
+  app decides what `"admin"` / `"editor"` / `"viewer"` mean. Stored
+  in `app_user_roles` (composite PK so `add` is idempotent).
+- The full `AppUser` record returned by every `users::*` getter now
+  carries a `roles` array.
+- `migrations/0031_app_user_roles.sql`.
+- **Role permission matrices / hierarchy / role registry are
+  explicitly v1.2 work** — v1.1.8 does not pre-commit to a model
+  that would lock in a wrong API.
+
+### Added — Admin HTTP surface
+
+- `GET / POST / PATCH / DELETE /api/v1/admin/apps/{id}/users` and
+  `/users/{user_id}` — list, get, create, update, delete.
+- `POST /users/{user_id}/reset-password` — returns a one-shot reset
+  token in the response body (TTL 1h). No email is sent — that's
+  the SDK's `users::request_password_reset`.
+- `POST /users/{user_id}/revoke-sessions` — bulk revoke for that
+  user.
+- `GET / POST / DELETE /api/v1/admin/apps/{id}/invitations` and
+  `/invitations/{invite_id}` — list, create, revoke pending.
+- Capability gating: `AppUsersRead` for reads, `AppUsersWrite` for
+  CRUD, `AppUsersAdmin` for admin-mediated verbs + invitations. All
+  three map to existing scopes (`script:read` / `script:write`) —
+  **no new scope** (seven-scope commitment).
+- DTOs never include password hashes, session tokens, or unrotated
+  reset tokens.
+
+### Added — Dashboard Users tab
+
+- `apps/[slug]/users/+page.svelte` — list, create form, edit modal,
+  revoke-sessions, reset-password (one-shot token displayed once),
+  delete. Sub-route `users/invitations/+page.svelte` for pending
+  invitations (list, create with optional inline email template,
+  revoke).
+- The main app-detail tab strip gains a Users entry above Files.
+- `@picloud/dashboard` 0.13.0 → 0.14.0.
+
+### Changed — Realtime: drop plaintext signing-key column (F1)
+
+- `migrations/0032_drop_plaintext_realtime_signing_key.sql` —
+  guard query + `ALTER TABLE app_secrets DROP COLUMN IF EXISTS
+  realtime_signing_key`. The guard refuses to apply if any row still
+  has plaintext but no encrypted counterpart.
+- v1.1.7's `migrate_plaintext_keys` startup task and its call from
+  `build_app` are deleted; the read path now consults only the
+  encrypted columns.
+
+### Changed — Realtime: `auth_mode = 'session'` (F3)
+
+- `migrations/0033_topics_auth_mode_session.sql` widens the
+  `topics_auth_mode_check` CHECK to allow `'session'` alongside
+  `'public'` and `'token'`.
+- `RealtimeAuthorityImpl` gains a `UsersService` dependency; the
+  Session branch of `authorize_subscribe` delegates to
+  `verify_session_for_realtime(app_id, token)` (same DB lookup +
+  sliding-TTL bump as the SDK's `users::verify`, but app_id is
+  taken from the topic row, not a script).
+- Dashboard Topics tab gains `session` as a third radio option.
+- `token` (HMAC) validator is unchanged; both coexist per topic.
+
+### Notes
+
+- New env vars (all with documented defaults):
+  - `PICLOUD_APP_USER_SESSION_TTL_HOURS` (24)
+  - `PICLOUD_APP_USER_SESSION_ABSOLUTE_HOURS` (720 = 30d)
+  - `PICLOUD_APP_USER_VERIFICATION_TTL_HOURS` (48)
+  - `PICLOUD_APP_USER_PASSWORD_RESET_TTL_HOURS` (1)
+  - `PICLOUD_APP_USER_INVITATION_TTL_DAYS` (7)
+- SDK schema 1.8 → 1.9 (additive surface: `users::*` + `session`
+  topic auth mode).
+- Workspace version 1.1.7 → 1.1.8.
+- `@picloud/client` does NOT bump in v1.1.8 — its `auth.login` /
+  `auth.logout` helpers already call dev-defined endpoints;
+  nothing to change in the client.
+- New weekly GC sweep (`spawn_app_user_token_gc`) prunes expired /
+  revoked / consumed rows across the four new token tables.

+**Current focus: v1.2 _Hierarchies_ — groups + the declarative project tool** ([docs/design/groups-and-project-tool.md](docs/design/groups-and-project-tool.md)). That doc's §11 uses its own **Phase 1–6 numbering, distinct from the blueprint product-phase numbering above — do not conflate them** (its "Phase 3" = group-inherited config, not admin auth). Implemented on `feat/groups-*` branches: §11 Phase 1 (declarative `pic plan`/`apply`/`prune` + env overlays), Phase 2 (single-parent groups tree + hierarchy-aware RBAC), Phase 3 (group-inherited, env-scoped `vars` + secrets resolved **live** via a recursive CTE — no materialized cache), Phase 4-lite (group-owned **endpoint** scripts: `scripts` polymorphic owner in `0050_group_scripts.sql`, `get_by_name_inherited`/`is_invocable_by_app` chain resolution, inherited `invoke()` + declarative route/trigger binding — all **live**, no body materialization), Phase 5 (the **declarative project tool maps onto the group tree**: the reconcile engine generalized to `ApplyOwner{App|Group}`, a `[group]` manifest kind, and a single atomic **tree apply** — `pic plan/apply --dir` reconciles a whole directory tree of `picloud.toml` nodes in one Postgres transaction, groups-before-apps so an app route can bind a group script created in the same tx; the bound token folds in each group's `structure_version`. Multi-repo single-owner/attach-point and per-env approval gating are deferred; groups pre-exist), Phase 4b (group **modules** + the **lexical (sealed-by-default) import resolver**, §5.5: owner-polymorphic `ModuleScript`, origin-rooted `ModuleSource::resolve` walking the importing node's chain, `ExecRequest.script_owner` threaded from every dispatch + `invoke()` site, `_source`-driven lexical chaining in `PicloudModuleResolver` with the compiled-module cache re-keyed by `ScriptId`, group modules/imports allowed, single-node dangling-import `plan` check — an inherited group script's imports **seal to the group**, a leaf can't shadow them). Next: §5.5 **opt-in extension points** (the one deferred §5.5 piece) or §11.6 (group-level collections, v1.3).
+
+**Data-model invariant:** app-owned data-plane tables (KV, docs, files, …) start with `app_id UUID NOT NULL REFERENCES apps(id) ON DELETE CASCADE`; the group-inheritable tables — _config_ (`vars`, `secrets`) and now group-owned _code_ (`scripts`, `0050`) — instead carry a **polymorphic owner**: nullable `group_id` and `app_id` with an exactly-one CHECK and per-owner partial-unique indexes (config is `ON DELETE CASCADE`, scripts `RESTRICT` — code is not data). Inheritance resolves **live** down `apps.group_id → groups.parent_id` via `CHAIN_LEVELS_CTE` (no materialized view); nearest-owner-wins with an app's own row shadowing the inherited one (CoW). Every Rhai SDK call resolves its app from `cx.app_id`, never a script-passed arg, and a group script always runs under the *inheriting* app's `cx.app_id` (the cross-app isolation boundary).

+# E2E Test #2 — "Stash" (paste + file-drop) + security matrix
+
+**Date:** 2026-06-13 · **Build:** v1.1.9 · **Instance:** host `picloud` on `127.0.0.1:8099`
+(dev mode, `PICLOUD_FILES_MAX_FILE_SIZE_BYTES=1048576`, SSRF guard on, SMTP unset), Postgres in
+Docker. Driven entirely through the `pic` CLI; data-plane traffic via `curl`.
+
+## Goal
+
+Second end-to-end pass. The first test (To-Do, `E2E_TODO_REPORT.md`) covered users/docs/pubsub/
+cron/routes/domains/topics. This one builds a **new** app to exercise the *untested* half of the
+platform — **kv, files, queue, invoke, secrets, api-keys, dead-letters, async + two-param routes**
+— and then runs a **10-probe security matrix**. Findings: feature/CLI gaps + security verdicts.
+
+## Verdict
+
+**Every feature worked** end-to-end, and **every security control held except one Low-severity
+gap** (reserved-path validation is case-sensitive). Highlights of what's *good*: cross-app
+isolation is airtight, the SSRF guard blocks cloud-metadata, size/op caps fire before authz, and
+internal script errors are scrubbed from responses with a correlation id. Two notable
+**observability/ergonomics gaps** (trigger executions invisible to `pic logs`; the `.trim()`/`.replace()`
+return-`()` footgun) and the expected CLI-coverage gaps round it out.
+
+---
+
+## The app — "Stash" (built CLI-only, no raw admin curl)
+
+A pastebin with file attachments and a background word-count worker. 9 scripts, 6 routes, a queue
+consumer trigger, a dead-letter trigger, 2 API keys, 1 secret — all via `pic`.
+
+| Feature exercised | How | Result |
+|---|---|---|
+| **kv** | paste store, hit counter, `/stats` aggregates, event log | ✅ get/set/list round-trip |
+| **files** | `files::create` from base64 blob + `get`/`head`, two-param download route | ✅ bytes round-trip (`"hello attachment bytes"`, size 22) |
+| **queue** | `queue::enqueue("ingest")` + `create-from-json --kind queue` consumer | ✅ worker fired |
+| **invoke** | worker → `invoke("analyzer", #{text})` function-to-function | ✅ returns word count |
+| **secrets** | `pic secrets set` (stdin) + `secrets::get` to gate `/stats` | ✅ 401 w/o token, 200 with |
+| **async route** | `routes create --dispatch async` for `POST /events` | ✅ **202** + execution_id |
+| **dead-letters** | poison job → 3 attempts → DL row; `pic dead-letters replay` | ✅ captured + replayed (+9 words) |
+| **api-keys** | `pic api-keys mint --scope … [--app …]` | ✅ minted, scopes enforced (below) |
+| **two-param route** | `/pastes/:code/files/:fid` | ✅ both params captured |
+
+End-to-end stats after the run: `{total_pastes: 2, total_words: 13}` — proving queue → worker →
+invoke → kv all fired on real Postgres rows + on-disk file bytes.
+
+---
+
+## Security matrix (10 probes, all reproduced live)
+
+| # | Probe | Verdict | Evidence |
+|---|---|---|---|
+| **S1** | Cross-app isolation | ✅ HOLDS | A script in app `evil` doing `kv…list()` / `secrets::get("admin-token")` / `files…list()` returned `{paste_keys:[], attachment_count:0, stolen_secret:null, my_secret_names:[]}`. `app_id` derives from `cx.app_id`; no SDK call takes a script-passed app_id. |
+| **S2** | Secret confidentiality | ✅ HOLDS | `pic secrets ls` shows names only; the plaintext `sup3r-s3cret-admin` does **not** appear anywhere in the server log even though `/stats` reads it each request. |
+| **S3** | API-key scope + app-binding | ✅ HOLDS | `script:read` key → **403** on `POST /apps` and `GET /admins`, **200** on in-scope `GET /scripts`. `app:admin` key bound to `stash` → **403** on app `evil`. `instance:admin` + `--app` → **422**. Unknown scope `bogus:scope` → rejected by CLI. |
+| **S4** | Sandbox op-budget | ✅ HOLDS | `loop {}` → **HTTP 507 "execution exceeded operation budget"** in **0.30 s**; `/healthz` still `ok` (no hang). |
+| **S5** | Value/size caps | ✅ HOLDS | Oversized kv write rejected (HTTP 502). Notably the detail (`"Length of string too large"`) was **scrubbed from the response** and logged with `correlation_id` — good error hygiene. Caps are checked before authz, so anonymous callers can't DoS. |
+| **S6** | Reserved-path prefixes | ⚠️ **GAP (Low)** | `/api/x`, `/admin/x`, `/healthz`, `/version` → correctly **422**. But case variants `/API/v2/x`, `/Admin/x`, `/HEALTHZ` were **accepted**. See finding below. |
+| **S7** | Files path traversal | ✅ HOLDS | `files::collection("../../../etc")` → `"invalid collection name: must not contain '/', '\\', '..', or NUL"`; a non-UUID file id → not found. No FS escape. |
+| **S8** | docs filter injection | ✅ HOLDS | `docs::find(#{ "x'); DROP TABLE docs;--": 1 })` → ran safely, `count=0`; the `docs` table still exists (`to_regclass` = true). Values/paths are bound as `$N` params. |
+| **S9** | SSRF via `http::` | ✅ HOLDS | `http::get("http://127.0.0.1:8099/healthz")` → `"blocked by SSRF policy: loopback"`; `http://169.254.169.254/…` (cloud metadata) → `"blocked by SSRF policy: link-local"`. |
+| **S10** | Anonymous data-plane access | ℹ️ By design (caveat) | Every Stash route is public (no auth) yet freely uses kv/secrets/files/queue. `script_gate` returns `Ok` when `principal.is_none()` — the *script* is the gate. Correct per design, but a sharp threat-model edge (see note). |
+
+### S6 — reserved-path validation is case-sensitive (Low)
+**What:** route-creation rejects the exact reserved prefixes but accepts case variants:
+```
+pic routes create --path /api/x   -> 422 "path '/api/x' is reserved"
+pic routes create --path /API/v2/x -> Created route … (GET * /API/v2/x)   # accepted
+pic routes create --path /HEALTHZ  -> Created route …                      # accepted
+pic routes create --path /Admin/x  -> Created route …                      # accepted
+```
+**Current impact — Low, *not* a full bypass:** path matching is case-*sensitive*, so a request to
+the real lowercase `/api/v2/x` still 404s (the system namespace is safe); only the exact
+mixed-case path serves the script (`GET /API/v2/x` → 200, `/HEALTHZ` → 200). Real `/healthz`
+still returns `ok` from the top-level handler.
+**Why it still matters:** (1) inconsistent enforcement of a stated security boundary; (2) lets a
+tenant publish convincing look-alike paths (`/Admin/login`, `/API/v1/…`) for phishing or log
+confusion; (3) **fragile** — method matching is already case-insensitive (`matcher.rs:275`); if
+path matching is ever made case-insensitive too, this instantly becomes a real shadowing bypass
+of `/api/`, `/admin/`, `/healthz`. The validation should be the durable guard.
+**Fix:** normalize case before the reserved check in `orchestrator-core/src/routing/pattern.rs`
+(`check_reserved` ~line 110) — compare `raw.to_ascii_lowercase()` against the reserved list (or
+reject any case-insensitive match).
+
+### S10 — anonymous public scripts have full app data-plane access (design caveat)
+Not a bug, but worth surfacing for users: a *public* (unauthenticated) route's script can read/write
+**all** of the app's kv, docs, files, secrets, and queue — the platform only gates *authenticated*
+principals; for anonymous ingress the script itself must enforce access. A developer who assumes
+"this route is public" ≠ "this code can read every secret in my app" could over-expose data. Worth
+a prominent doc callout near the SDK auth model.
+
+---
+
+## Feature / CLI gaps
+
+- **G1 — trigger executions are invisible to `pic logs`.** After successful queue-worker and
+  analyzer runs, `pic logs <worker>` and `pic logs <analyzer>` were **empty**. Trigger-dispatched
+  executions (queue/cron/dead-letter/invoke) don't surface in the per-script log tail — the only
+  built-in visibility into worker activity is **dead-letters (failures only)** or the script's own
+  side effects. This is a real observability gap for background workloads. *Suggest: include
+  trigger executions in the logs surface, or add a `pic logs --trigger`/events view.*
+- **G2 — no `pic kv` / `files` / `queues` / `members` commands.** Data-plane stores are
+  script/HTTP-only (no admin CLI to inspect kv/files/queue contents; queues are read-only HTTP).
+  App **membership** (`/apps/{id}/members`) also has no CLI — multi-user app roles can't be managed
+  with `pic`. *(Confirmed absent via `pic <cmd> --help`.)*
+- **G3 — no per-script sandbox/timeout flags in `pic deploy`/`scripts`.** `timeout_seconds`,
+  `memory_limit_mb`, and sandbox overrides are only settable via the raw scripts API or instance
+  env (`PICLOUD_SANDBOX_MAX_*`). A developer can't cap a single script's runtime from the CLI.
+- **G4 — uneven trigger wrappers.** Only `kv`, `cron`, `dead-letter` have first-class
+  `pic triggers create-*` wrappers; `docs`/`files`/`pubsub`/`queue`/`email` require hand-built
+  `create-from-json --kind … --body '{…}'`. Works, but the developer must know each body schema.
+- **G5 — `email::send` unusable in dev.** Returns `"email is not configured: set
+  PICLOUD_SMTP_HOST/USER/PASSWORD"`. Expected (no silent drop), but the email feature can't be
+  exercised at all without an SMTP relay — worth a documented local-dev fake/sink.
+- **G6 — Rhai `.trim()` returns `()` (in-place mutation footgun).** Same family as `.replace()`
+  (already documented). `let t = text.trim()` sets `t` to unit; my analyzer dead-lettered with
+  `Function not found: split((), …)` until rewritten to `text.trim();` as a statement. *Suggest:
+  extend the existing stdlib footgun note to list `trim`/`to_upper`/`to_lower` etc., not just
+  `replace`.*
+
+## Things done especially well (no action)
+- Cross-app isolation has no script-controlled `app_id` anywhere — the boundary is structural.
+- SSRF guard covers loopback **and** link-local (cloud-metadata `169.254.169.254`), and blocks at
+  every redirect hop.
+- Size/operation caps are enforced **before** authz, so anonymous public scripts can't DoS the DB.
+- Script runtime errors are **scrubbed** from the HTTP response and logged with a `correlation_id`
+  — no internal detail leaks to the caller.
+- `deploy`/`apps create` honor `--output json` (the earlier F1 fix), so the whole build scripts
+  cleanly with captured ids.
+
+## Reproduction / teardown
+Scripts under `/tmp/stash/*.rhai`; apps `stash` + `evil` and their data persist in the dev
+Postgres. Server: `target/debug/picloud` on `:8099` (see Phase 0 env). Teardown: kill the host
+`picloud`; `docker compose down [-v]`. (Note: the S6 probe left harmless `/API/v2/x`, `/HEALTHZ`,
+`/Admin/x`, `/Api/y` routes on `stash` — they vanish with the app.)
+
+## Priority
+**S6** is the only code-level finding (Low — confirm-and-harden the reserved-path check). **G1**
+(trigger-execution observability) is the most impactful *developer-experience* gap for anyone
+running background workers. Everything else is documented-behavior or known CLI-coverage gaps.

+# E2E Developer Test — Rich To-Do App via the `pic` CLI
+
+**Date:** 2026-06-12 · **Tester:** manual end-to-end walkthrough · **Build:** v1.1.9
+(`product 1.1.9`, `sdk 1.10`, `api 1`, `schema 42`) · **Instance:** host-run `picloud`
+in dev mode on `127.0.0.1:8099`, Postgres via `docker compose up postgres`.
+
+## Goal
+
+Act as a developer building a real product — a multi-user **To-Do app** (end-user
+signup/login, per-user todos in document storage, full HTTP CRUD, a nightly cron cleanup,
+and a realtime activity feed) — **entirely through the `pic` CLI**, and record every place
+the happy path forced me off the CLI or behaved surprisingly.
+
+## Verdict
+
+**The platform can build and run the whole app — every capability exists and works.** The
+data-plane journey (register → login → create → list → complete → ownership-checked delete →
+auth rejection) is correct, `users::*` auth is solid, `docs::*` storage works, durable pubsub
+fans out to an external SSE subscriber, and the cron trigger registers and runs.
+
+**But a CLI-only developer cannot reach the finish line.** Two control-plane operations have
+**no `pic` command at all** and forced me to drop to raw `curl` against the admin API — and
+without the first one, *every* app created through the CLI serves `404` on every route.
+
+> ## ✅ RE-TEST 2026-06-12 — ALL GAPS CLOSED (verified live)
+>
+> After remediation (commits `04a24ea`, `ae2134e`, `7ffbb8d`, `b831138`), I rebuilt the **entire
+> app a second time CLI-only, with zero raw `curl` against the admin API** (app `todoapp2`,
+> domain `todos2.local`). Every finding below is now fixed and verified end-to-end. See the
+> [Re-test verification](#re-test-verification--2026-06-12) section at the bottom for the
+> per-finding evidence. The original findings are preserved as-is for the record.

+
+## BLOCKERS — no CLI path; app cannot serve traffic without raw API
+
+### B1. No domain-claim command — every CLI-created app 404s until you `curl`
+**Severity: BLOCKER (highest-impact finding).**
+
+After `pic apps create`, deploying scripts, and binding routes, *every* request 404'd:
+```
+$ curl -s -X POST localhost:8099/auth/register -d '{...}'
+{"error":"no route matches POST /auth/register"}
+```
+Reason: Host→app dispatch resolves `localhost` to the **default** app; a non-default app's
+routes are unreachable until the app claims a domain. But `pic apps` exposes only
+`ls / create / show / delete` — **no domain subcommand** — and there is no top-level
+`pic domains` either. The only way through is the raw admin API:
+```
+curl -X POST localhost:8099/api/v1/admin/apps/$APP/domains \
+     -H "authorization: Bearer $TOKEN" -d '{"pattern":"todos.local"}'
+```
+After that, routing works (with `Host: todos.local`). **A developer who only knows the CLI is
+hard-stuck here** — they have created scripts and routes that silently never match, with no CLI
+affordance explaining why. *Fix: add `pic apps domains {ls,add,rm}` (the API already exists in
+`apps_api.rs`).*
+
+### B2. No pubsub topic-registration command — realtime feed needs raw API
+**Severity: BLOCKER for the realtime requirement.**
+
+Scripts can `pubsub::publish_durable("activity", …)` fine (publishing needs no pre-registration),
+but an **external** SSE subscriber on `/realtime/topics/activity` only receives events once the
+topic is registered as `external_subscribable`. There is no `pic topics` command. Worse, the
+`pic triggers` help text actively points you at `create-from-json` "for kinds the CLI doesn't
+expose … (docs/files/pubsub/…)" — but that creates a *pubsub trigger* (run a script on publish),
+which is a different concept and does **not** register a topic for outside subscribers. Workaround:
+```
+curl -X POST localhost:8099/api/v1/admin/apps/$APP/topics \
+     -H "authorization: Bearer $TOKEN" \
+     -d '{"name":"activity","external_subscribable":true,"auth_mode":"public"}'
+```
+Once registered, the SSE path works perfectly — a subscriber received:
+```
+data: {"message":{"kind":"created","title":"Realtime test", …},"topic":"activity", …}
+```
+*Fix: add `pic topics {ls,create,update,rm}` (API exists in `topics_api.rs`).*
+
+---
+
+## FRICTION — completable via CLI, but sharp edges
+
+### F1. `pic deploy` / `apps create` ignore `--output json`
+They print human strings even in JSON mode, so you can't capture the new id:
+```
+$ pic --output json deploy register.rhai --app todos-e2e
+Created register v1                      # not JSON — no id emitted
+$ pic --output json apps create todos-e2e
+Created app todos-e2e                    # not JSON — no id emitted
+```
+Every later `routes`/`triggers`/domain/topic call needs that id, so each create forces a
+follow-up `scripts ls --output json | parse` or `apps show`. This breaks naive scripting/CI.
+*Fix: emit the created object as JSON under `--output json`.*
+
+### F2. No `pic users` command for app end-users
+The full `/api/v1/admin/apps/{id}/users` surface exists (list, get, reset-password,
+revoke-sessions, invitations) but has no CLI wrapper, so a developer has zero CLI visibility
+into who registered. Listing the two users I created required raw API. *Fix: `pic users …`.*
+
+### F3. Password login is interactive-only
+`pic login` offers `--url` and `--token` but **no** `--username`/`--password`. Non-interactive
+(CI) auth means obtaining a bearer out-of-band (raw `POST /auth/login`, or pre-minting an
+`pic api-keys` token — chicken-and-egg if you have no token yet). *Fix: optional
+`--username` + `--password-stdin`.*
+
+### F4. No `ctx.request.method` in scripts → one script per verb
+The request map exposes `path, headers, body, params, query, rest` but **not the HTTP method**
+(`engine.rs` builds the map without it). A script therefore cannot branch GET vs POST on the
+same path, forcing a separate script + method-scoped route per verb. My app needed **7 scripts
+where ~3 would do** (`/todos` GET+POST and `/todos/:id` PATCH+DELETE each had to split).
+*Fix: add `ctx.request.method`.*
+
+---
+
+## SDK / SCRIPTING SHARP EDGES — platform correct, but the natural code fails at runtime
+
+### S1. `users::find_by_email` is forbidden for anonymous (public) callers
+The obvious registration pattern — "look up email, 409 if taken, else create" — fails:
+```
+{"error":"Runtime error: users: forbidden"}   # HTTP 502
+```
+`find_by_email` deliberately requires an authenticated principal (anti-enumeration, audit
+finding F-S-003 in `users_service.rs`), while `users::create` is allowed for anonymous public
+scripts. So a self-serve register script **must skip the pre-check** and rely on `create`'s
+uniqueness error instead. The SDK doc-comment for `find_by_email` shows it with no caveat, so
+this only surfaces as a runtime 502. *Fix: document the principal requirement on
+`find_by_email`; consider a dedicated `users::email_available()` that's safe for anonymous use.*
+
+### S2. Response envelope is `statusCode`-gated (silent double-nesting)
+A returned map is unwrapped as `{statusCode, headers, body}` **only if it contains
+`statusCode`**. Without it, the *entire* map becomes the literal body — so `#{ body: #{token} }`
+returns `{"body":{"token":…}}`, not `{"token":…}`. I hit this on login/list/update until I added
+`statusCode: 200`. The doc-comment examples don't flag it. *Fix: doc note, or treat a lone
+`body` key as an envelope.*
+
+### S3. Rhai `String.replace()` mutates in place and returns `()`
+`let token = auth.replace("Bearer ", "")` sets `token` to unit, then `users::verify(())` →
+`Function not found: users::verify (())`. Stock Rhai semantics, but a JS/Python dev will hit it;
+`auth.sub_string(7)` after `starts_with("Bearer ")` is the correct idiom. *Fix: a one-line note
++ a bearer-parsing example in the stdlib reference.*
+
+---
+
+## ONBOARDING
+
+### O1. Dev mode needs a second, undocumented acknowledgement var
+`PICLOUD_DEV_MODE=true` alone aborts at startup:
+```
+Error: PICLOUD_DEV_MODE=true without PICLOUD_SECRET_KEY requires an explicit acknowledgement.
+Set PICLOUD_DEV_INSECURE_KEY=i-understand-this-is-insecure to confirm …
+```
+CLAUDE.md and the dev notes mention only `PICLOUD_DEV_MODE=true`. Good security default, but the
+error message is the sole documentation. *Fix: document `PICLOUD_DEV_INSECURE_KEY` next to
+`PICLOUD_DEV_MODE`.*
+
+---
+
+## What worked well (no changes needed)
+
+- End-to-end data plane fully correct: register, login, per-user list, create, complete, delete,
+  **ownership 403** (Bob can't touch Alice's todo), **401** on missing/garbage token.
+- `users::*`: login returns a 43-char session token, `verify` resolves it (sliding TTL),
+  password hashing + email uniqueness enforced.
+- `docs::collection(...).find({field})` filtered correctly; full-blob `update` semantics as
+  documented.
+- `pubsub::publish_durable` → external SSE delivery worked once the topic was registered.
+- Cron trigger registered; `pic invoke <cleanup-id>` ran it → `{"removed":0}`.
+- `pic deploy` **updates in place** (v1→v2, same id) — no duplicate scripts on redeploy.
+- `pic routes match` resolved param routes and captured `param.id`; empty param segment
+  (`/todos/`) correctly did **not** match.
+- `pic logs <id>` listed executions with success/error status.
+

+Server: `docker compose up -d postgres`; then host-run with
+`PICLOUD_DEV_MODE=true PICLOUD_DEV_INSECURE_KEY=i-understand-this-is-insecure
+PICLOUD_BIND=127.0.0.1:8099 PICLOUD_ADMIN_USERNAME=admin PICLOUD_ADMIN_PASSWORD=admin
+target/debug/picloud`. CLI: `cargo build -p picloud-cli` → `target/debug/pic`. App scripts:
+`/tmp/todo-app/*.rhai`. Every command + captured output above was run live against this instance.
+
+## Priority recommendation
+
+The two CLI gaps that turn "I built an app" into "…but it 404s and has no realtime" are **B1
+(domain claims)** and **B2 (topic registration)**. Both already have working admin APIs; they
+just need thin `pic` wrappers (mirroring the existing `routes`/`triggers` commands). Ship those
+two and a CLI-only developer can build this entire app without ever touching `curl`.
+
+---
+
+# Re-test verification — 2026-06-12
+
+Second pass after the fix commits (`04a24ea` CLI gaps, `ae2134e` `ctx.request.method`,
+`7ffbb8d` `users::email_available`, `b831138` docs). I rebuilt the whole app as a **fresh,
+CLI-only** flow against the same live instance — new app `todoapp2`, domain `todos2.local`,
+**no raw `curl` to any `/api/v1/admin/*` endpoint**. Data-plane HTTP calls (the app's own
+traffic) still use curl, as a real end-user client would.
+
+## Status table
+
+| # | Finding | Status | Evidence |
+|---|---------|--------|----------|
+| B1 | No domain-claim command | ✅ Fixed | `pic apps domains add todoapp2 todos2.local` → claim created; routes then match. Help text even explains the 404-without-claim trap. |
+| B2 | No pubsub topic command | ✅ Fixed | `pic topics create --app todoapp2 activity --external` → `external_subscribable:true`; SSE subscriber received the published event. |
+| F1 | `deploy`/`apps create` ignore `--output json` | ✅ Fixed | Both now emit the full JSON object; I captured every script id straight from `deploy --output json` (no follow-up `scripts ls`). |
+| F2 | No `pic users` command | ✅ Fixed | `pic users ls/show/reset-password` all work; listed Carol+Dave, showed Carol, minted a 1-shot reset token. |
+| F3 | Password login interactive-only | ✅ Fixed | `printf 'admin' \| pic login --username admin --password-stdin` logged in non-interactively. |
+| F4 | No `ctx.request.method` | ✅ Fixed | One `todos.rhai` now serves **GET+POST** and one `todo_item.rhai` serves **PATCH+DELETE** by branching on `ctx.request.method`; unsupported verb returns my `405`. Script count dropped 7→5, routes 6→4. |
+| S1 | `find_by_email` forbidden for anon registration | ✅ Fixed | New `users::email_available(email)` → bool works from the anonymous register route; duplicate email now returns a clean `409`, no more `users: forbidden`/502. |
+| S2 | `statusCode`-gated envelope (double-nest) | ✅ Documented | Behaviour noted in stdlib docs (`b831138`); my scripts use explicit `statusCode` and responses are flat. |
+| S3 | Rhai `replace()` returns `()` footgun | ✅ Documented | Bearer-parsing note added; `auth.sub_string(7)` after `starts_with` is the idiom used. |
+| O1 | Dev-mode needs undocumented ack var | ✅ Documented | `PICLOUD_DEV_INSECURE_KEY` now documented alongside `PICLOUD_DEV_MODE`. |
+
+## CLI-only build transcript (abridged, all succeeded)

+carol DELETE                              200
+PUT /todos (unsupported verb)             405  (in-script method guard)
+no-auth GET /todos                        401
+realtime SSE on activity                  received {"kind":"created",...,"topic":"activity"}
+```
+
+**Conclusion: a CLI-only developer can now build this entire app — auth, storage, CRUD,
+ownership, cron, and a realtime feed — without ever touching `curl` against the admin API.**

+## 2. Queue dispatcher design notes
 
----
+**The queue table IS the outbox for queue semantics.** No
+double-buffering through `outbox.source_kind = 'queue'`. The
+dispatcher's `tick_queue_arm` lists active consumers
+(`triggers.list_active_queue_consumers()` — joins `triggers` +
+`queue_trigger_details` for enabled `kind = 'queue'` rows) and runs
+one atomic claim per `(app_id, queue_name)` per tick.
 
-## 2. Encryption infrastructure notes
+Claim shape (single round trip):
 
-- **Module:** `crates/shared/src/crypto.rs` (`picloud_shared::crypto`).
-- **Master-key sourcing** (`MasterKey::from_env` → `resolve`):
-  - `PICLOUD_SECRET_KEY` = base64 of exactly 32 bytes. Missing →
-    `MasterKeyError::Missing` (fatal); non-base64 → `Malformed`; wrong
-    length → `WrongLength`. **Sourced in `main.rs::run_server` before any
-    DB work** — `build_app` takes the `MasterKey` as a parameter (so
-    tests pass a fixed key and don't mutate process env).
-  - Dev fallback: deterministic key (`SHA-256("picloud-dev-master-key-v1.1.7")`)
-    used ONLY when `PICLOUD_SECRET_KEY` is unset **AND**
-    `PICLOUD_DEV_MODE=true`, with a prominent `warn!`. No quiet
-    unencrypted mode.
-- **aes-gcm version:** `0.10` (features `aes`, `alloc`). `Aes256Gcm`.
-- **Nonce generation:** 12 bytes from `rand::thread_rng().fill_bytes`
-  (OS-CSPRNG-seeded), per-encryption.
-- **Storage layout:** ciphertext **with the 16-byte GCM auth tag
-  appended** (RustCrypto `Aead`-trait layout — `encrypt` returns
-  `ciphertext || tag`, `decrypt` consumes the same). The 12-byte nonce is
-  stored in a separate column. `MasterKey`'s `Debug` is redacted.
-- **Plaintext cap (secrets):** 64 KB default, enforced in
-  `secrets_service::seal` (the SDK boundary) → `SecretsError::TooLarge`
-  with limit + actual size. Override: `PICLOUD_SECRET_MAX_VALUE_BYTES`.
-- **Key rotation:** out of scope. Documented in CHANGELOG + the module
-  docs that changing `PICLOUD_SECRET_KEY` orphans all ciphertext.
+```sql
+UPDATE queue_messages
+SET claim_token = $3, claimed_at = NOW(), attempt = attempt + 1
+WHERE id = (
+    SELECT id FROM queue_messages
+    WHERE app_id = $1 AND queue_name = $2
+      AND claim_token IS NULL
+      AND (deliver_after IS NULL OR deliver_after <= NOW())
+    ORDER BY enqueued_at
+    FOR UPDATE SKIP LOCKED
+    LIMIT 1
+)
+RETURNING id, app_id, queue_name, payload, enqueued_at, attempt, max_attempts
+```
 
----
+`SKIP LOCKED` keeps concurrent dispatchers (cluster mode v1.3+) safe.
+The `claim_token` (fresh `Uuid::new_v4()` per claim) is the lease
+guarantee: ack and nack both filter `WHERE id = $1 AND claim_token =
+$2`, so a stale dispatcher whose visibility-timeout expired can't
+accidentally delete or re-defer a message that's been re-claimed.
 
-## 3. Secrets notes
+**Ack** (handler returned successfully):
+`DELETE FROM queue_messages WHERE id = $1 AND claim_token = $2`.
 
-- `SecretsService` (trait, `picloud-shared`) → `SecretsServiceImpl` +
-  `PostgresSecretsRepo` (`manager-core`) → Rhai bridge
-  (`executor-core/src/sdk/secrets.rs`). Collection-less; `app_id` from
-  `cx.app_id`.
-- **JSON round-trip:** `set` serializes the value to JSON bytes, caps,
-  encrypts; `get` decrypts + deserializes — a String returns a String
-  (not a JSON-quoted `"\"…\""`). Verified by unit + bridge tests.
-- **No ServiceEvent emission** (secret writes don't fire triggers).
-- Admin API: `GET/POST/DELETE /api/v1/admin/apps/{id}/secrets`; list
-  returns names + `updated_at` only.
-- Authz: `Capability::AppSecretsRead/Write` → `script:read`/`script:write`.
-  No new Scope variants (seven-scope commitment held).
+**Nack** (handler threw, `attempt < max_attempts`):
+`UPDATE … SET claim_token = NULL, claimed_at = NULL, deliver_after =
+NOW() + retry_delay`. Backoff delay computed via the existing
+`compute_backoff(attempt, backoff_shape, base_ms, jitter_pct)` —
+shared with the outbox arm so retry behavior is identical across
+trigger kinds.
 
----
+**Dead-letter** (handler threw, `attempt >= max_attempts`): single
+transaction — `INSERT INTO dead_letters` with `source = "queue"`,
+`op = "receive"`, the original payload wrapped in a shape mirroring
+`TriggerEvent::Queue` (so the existing `fan_out_dead_letter` path on
+the outbox arm can fire registered `dead_letter` triggers off the new
+row without any special-casing), then `DELETE FROM queue_messages`.
 
-## 4. Email implementation notes
+**Visibility-timeout reclaim**: separate `tokio::spawn` task, ticks
+every `PICLOUD_QUEUE_RECLAIM_INTERVAL_MS` (default 30 000 ms). UPDATE
+joins `queue_messages` + `triggers` + `queue_trigger_details` and
+clears claims older than the per-queue `visibility_timeout_secs`. A
+crashed consumer thus loses its lease and the message becomes
+claimable again. **Verified** by `queue_e2e::queue_visibility_timeout_reclaim`
+(inserts a row with `claimed_at = NOW() - 60s`, `visibility_timeout =
+5s`; polls until either the dispatcher re-claims or the claim
+clears).
 
-- **SMTP transport:** `lettre 0.11` (`smtp-transport`,
-  `tokio1-rustls-tls`, `builder`, `hostname`). **Connection model:** one
-  connection per call (lettre default); pooling deferred to v1.2. The
-  transport sits behind an internal `EmailTransport` trait so the service
-  is unit-tested with a recording fake (no live SMTP).
-- **Disabled mode:** if HOST/USER/PASSWORD aren't all set,
-  `EmailServiceImpl::from_env` builds no transport and every `send`
-  returns `NotConfigured` (warned at startup). A malformed relay
-  descriptor is also logged and yields disabled mode (email is
-  non-critical; never blocks startup).
-- **Address validation:** hand-rolled RFC 5322-ish pre-check (single `@`,
-  non-empty local part, domain contains a dot, ≤320 bytes) followed by a
-  `lettre::Mailbox` parse (the authoritative validator). No deliverability
-  check.
-- **Size cap:** 25 MB on `message.formatted()`,
-  `PICLOUD_EMAIL_MAX_MESSAGE_BYTES`.
-- `email::send` forces text-only (ignores any `html`); `email::send_html`
-  requires `html` and builds `MultiPart::alternative_plain_html`.
-  `reply_to` defaults to `from`. `to`/`cc`/`bcc` accept a String or an
-  Array of Strings.
-- **Inbound normalization:** only the generic provider-agnostic JSON
-  shape `{from,to[],cc[],subject,text,html,message_id}` is accepted in
-  v1.1.7 — `from` required, rest default. Provider-specific unmarshallers
-  → v1.2. The expected shape is documented on the dashboard email-trigger
-  form.
+## 3. `invoke()` re-entrancy notes
 
----
+**Engine sharing** via `Engine::self_weak: OnceLock<Weak<Engine>>`.
+The picloud binary:
 
-## 5. Dead-letter handler fix notes
+```rust
+let engine = Arc::new(Engine::new(engine_limits, services));
+engine.set_self_weak(Arc::downgrade(&engine));
+```
 
-- **Call site:** `dispatcher::handle_failure`, the retry-exhaustion
-  branch. After `DeadLetterRepo::insert` (which returns the new
-  `DeadLetterId`), a new helper `fan_out_dead_letter` runs.
-- **What it does:** calls `TriggerRepo::list_matching_dead_letter(app_id,
-  source, row.trigger_id, Some(resolved.script_id))` (the method that had
-  no production caller) and inserts one outbox row per match
-  (`source_kind = DeadLetter`, the DL trigger's id + handler script id,
-  `trigger_depth + 1`, `origin_principal = the DL trigger's registered
-  principal`).
-- **Payload — built from the REAL `TriggerEvent::DeadLetter` variant**,
-  not the brief's §6 field list (see §7 deviations): `{ dead_letter_id,
-  original: Box::new(decoded row payload), attempts, last_error,
-  trigger_id, script_id, first_attempt_at, last_attempt_at }`. If the
-  outbox payload can't be decoded back into a `TriggerEvent` (so the
-  nested `original` can't be built), the fan-out is skipped — the
-  dead-letter row is still durably written.
-- **Recursion-stop:** unchanged. The `is_dead_letter_handler`
-  short-circuit at the top of `handle_failure` returns before the
-  exhaustion branch, so a DL handler's own failure is never re-dead-
-  lettered. No new guard needed.
-- **Tests verify the handler actually fires**
-  (`crates/picloud/tests/dispatcher_e2e.rs`, DB-gated):
-  `dispatcher_delivers_dead_letter_to_handler` now asserts BOTH row-create
-  AND handler-fire (inline doc updated);
-  `dispatcher_delivers_dead_letter_to_handler_actually_fires` asserts the
-  nested `original` KV event + `last_error`;
-  `dead_letter_source_filter_excludes_nonmatching` exercises the source
-  filter dimension; `dead_letter_handler_failure_does_not_recurse` proves
-  the recursion-stop (count stays at 1).
+`Engine::execute_ast` reads `self.self_arc()` (which upgrades the
+`Weak`) and threads `Option<Arc<Engine>>` through
+`sdk::register_all(...)` to the invoke bridge.
 
----
+**`Weak` is the right choice** — strong would make the Engine Arc
+cycle itself, leaking on drop. Cycle stays broken; the invoke bridge
+just gets `None` if the engine has been dropped (which only happens
+on shutdown).
 
-## 6. Realtime signing-key migration notes
+**Re-entry path** (inside `invoke.rs::invoke_blocking`):
 
-- **Two-phase**, as recommended. `0025_encrypt_realtime_keys.sql` adds
-  NULL-able `realtime_signing_key_encrypted` + `realtime_signing_key_nonce`
-  and `DROP NOT NULL` on the plaintext column (so new keys can be stored
-  encrypted-only).
-- **Repo:** `PostgresAppSecretsRepo` now holds the `MasterKey`. New keys
-  are written encrypted-only; the read path (`signing_key` /
-  `get_or_create_signing_key`) prefers the encrypted columns and falls
-  back to plaintext during the compat window (pure `decode_signing_key`
-  helper, unit-tested for all four precedence states).
-- **Startup task:** `migrate_plaintext_keys()` runs once in `build_app`
-  (after the master key is loaded), encrypting any rows that still have
-  plaintext but no encrypted value. Plaintext is **left in place** for
-  rollback safety. Idempotent.
-- **Plaintext column drop:** deferred to **v1.1.8** (documented in
-  CHANGELOG + the migration). Operators must upgrade through v1.1.7
-  (which performs the encryption) before v1.1.8.
-- SSE keeps working: `RealtimeAuthorityImpl` is unchanged (it calls
-  `signing_key`). Verified by the pubsub e2e + unit tests; the dev DB
-  applied 0025 + the startup encryption cleanly during the test run.
+1. Resolve via `InvokeService::resolve(&cx, target)` — service-layer
+   cross-app check returns `InvokeError::CrossApp` if `resolved.app_id
+   != cx.app_id`.
+2. Depth check **before** resolve — `cx.trigger_depth + 1 >
+   limits.trigger_depth_max` throws immediately (no wasted DB
+   round-trip).
+3. Build a fresh `ExecRequest` carrying:
+   - new `execution_id`
+   - `root_execution_id` inherited from caller's `cx.root_execution_id`
+   - `trigger_depth = cx.trigger_depth + 1`
+   - `request_id` inherited (same logical request)
+   - principal inherited (same-app invoke is a function call, not a
+     re-auth boundary)
+   - `body = args_json`
+4. Call `self_engine.execute(&resolved.source, req)` — synchronous,
+   on the SAME `spawn_blocking` thread. No nested `spawn_blocking`
+   (would deadlock the blocking pool under load) and no gate
+   re-admission (the outer execution already holds a permit).
+5. Return `json_to_dynamic(resp.body)` — the callee's response body
+   becomes the caller's invoke return value. Status code + headers
+   are dropped (the function-call mental model is "return value", not
+   "HTTP response").
 
----
+**Cross-app rejection point**: verified at three layers — repo
+returns the script row, service compares `resolved.app_id` to
+`cx.app_id`, and the dispatcher's `build_invoke_request` re-checks
+when firing an `invoke_async` outbox row (defense in depth — the
+service already enforced same-app at enqueue time, but a hand-edited
+row should still be rejected).
+
+**Depth-bound** integration tested by `invoke_e2e::invoke_depth_limit_exceeds_cleanly`
+— recursive script propagates the throw all the way up; outer
+caller's `try/catch` surfaces "invoke: depth limit exceeded (max 8)".
+
+## 4. `retry::*` notes
+
+**Closure passing** via Rhai's `FnPtr`. `retry::run(policy, fn_ptr)`
+is registered with `NativeCallContext` so the bridge can call
+`fn_ptr.call_within_context(ctx, ())` in a loop. The closure shares
+the caller's engine + cx — if the closure itself calls `invoke()`,
+the inner call goes through the invoke bridge (fresh cx with
+`trigger_depth + 1`), retry doesn't see or interfere with that.
+
+**Sleep mechanics**: `tokio::time::sleep(delay)` via
+`TokioHandle::block_on`. We're already inside the caller's
+`spawn_blocking` thread, so blocking the thread on a tokio sleep is
+fine — the runtime's worker pool isn't being held.
+
+**Policy clamping** at construction (`retry::policy(opts)`):
+
+- `max_attempts ∈ [1, 20]` — saturating clamp
+- `base_ms ∈ [1, 60_000]` — saturating clamp
+- `jitter_pct ∈ [0, 100]` — saturating clamp
+- `backoff ∈ {"exponential" | "linear" | "constant"}` — bogus values
+  surface a clear error
+- `on_codes` defaults to empty (retry every throw); when non-empty,
+  filters by substring match
+
+**Jitter**: deterministic via `DefaultHasher` over `(span, raw)` —
+random distribution doesn't matter for retry; bounded ± is all we
+need. Avoids pulling `rand` into the hot path.
+
+## 5. Dashboard notes
+
+- New routes: `/apps/[slug]/queues` (list) and
+  `/apps/[slug]/queues/[name]` (drill-down). Both use Svelte 5 runes
+  (`$state`, `$derived`, `$effect`) — matches the existing app
+  detail page's idioms.
+- Triggers tab gains a "Queue:receive trigger (v1.1.9)" form below the
+  Email form. Same `submitCreate*` pattern as the other forms; clears
+  state on success and re-loads the trigger list.
+- App-level nav gains a "Queues" link between Files and Dead letters,
+  guarded by `canAdmin` (same gate as the other operational tabs).
+- TypeScript types: `TriggerKind` admits `'queue'`, `TriggerDetails`
+  union admits the `{ kind: 'queue', queue_name, visibility_timeout_secs,
+  last_fired_at }` shape. `CreateQueueTriggerInput`, `QueueSummary`,
+  `QueueConsumer`, `QueueDetail` exported alongside.
+- `npm run check`: my changes typecheck clean. (The 149 pre-existing
+  errors are all in `tests/e2e/**/*.spec.ts` about `@playwright/test`
+  not being installed — unchanged from main.)
+- `dashboard/package.json` bumped to `0.15.0`.
+
+## 6. F1–F5 implementation notes
+
+**F1 — integration test density.** Four new DB-gated test binaries
+(all skip cleanly when `DATABASE_URL` is unset, mirroring the
+existing `dispatcher_e2e.rs` pattern):
+
+- `crates/picloud/tests/queue_e2e.rs` (4 tests, 33s runtime):
+  - `queue_receive_acks_on_success`
+  - `queue_receive_dead_letters_after_max_attempts`
+  - `queue_one_consumer_per_queue_rejected`
+  - `queue_visibility_timeout_reclaim`
+- `crates/picloud/tests/invoke_e2e.rs` (4 tests, 2s):
+  - `invoke_by_name_same_app_returns_value`
+  - `invoke_cross_app_rejects`
+  - `invoke_depth_limit_exceeds_cleanly`
+  - `invoke_async_enqueues_outbox_row`
+- `crates/picloud/tests/retry_e2e.rs` (3 tests, 2.5s):
+  - `retry_run_eventually_succeeds_inside_http_handler`
+  - `retry_run_surfaces_last_error_after_max_attempts`
+  - `retry_on_codes_filters_unmatched_errors`
+- `crates/manager-core/tests/migration_queue_messages.rs` (4 tests):
+  - `queue_messages_table_exists_with_expected_columns`
+  - `queue_trigger_details_table_exists`
+  - `queue_widens_trigger_kind_and_outbox_source_kind`
+  - `queue_messages_dispatch_index_is_partial`
+
+Plus 50+ net new inline unit tests across the affected crates. All
+pass against the docker-compose postgres on `localhost:15432`. See
+§8 for the literal `cargo test` output.
+
+**F2 — schema snapshot `BLESS=1` part of the gate.** Re-blessed via:
+
+```sh
+DATABASE_URL=postgres://picloud:picloud@localhost:15432/picloud \
+PICLOUD_ADMIN_USERNAME=dev PICLOUD_ADMIN_PASSWORD=dev \
+BLESS=1 cargo test -p picloud-manager-core --test schema_snapshot \
+  -- --include-ignored
+```
+
+Delta committed in `chore(v1.1.9): re-bless schema snapshot (0034 + 0035 delta)`.
+Matches the plan exactly: two new tables, three new partial indexes,
+widened `triggers.kind` + `outbox.source_kind` CHECKs, no unrelated
+drift.
+
+**F3 — fmt + clippy attestation as literal output.** See §8.
+
+**F4 — `TIMING_FLAT_DUMMY_HASH` dedup.** `crates/manager-core/src/auth_api.rs::login`
+now reads `crate::auth::TIMING_FLAT_DUMMY_HASH.to_string()` on the
+bad-email branch. Verification:
+
+```sh
+$ grep -rn 'argon2id\$v=19\$m=19456,t=2,p=1\$dGltaW5n' crates/
+crates/manager-core/src/auth.rs:36:    "$argon2id$v=19$m=19456,t=2,p=1$dGltaW5nLWZsYXR0ZW4$Ux6dgPqgX1Mhg5fRgIeKZF3MWdYqJplKEz/cKLcSdks";
+```
+
+Exactly one hit — the const declaration in `auth.rs`.
+
+**F5 — clippy cold-cache environmental constraint.** Used the
+incremental cache (no `cargo clean`). Verified by checking the
+`Checking <crate>` lines for test crates appear in the clippy output.
+CI will do the cold-cache attestation on its dedicated runner.
 
 ## 7. Decisions beyond the brief / deviations flagged
 
-1. **`inbound_secret` stored ENCRYPTED (user-approved deviation).** The
-   brief defaulted to a plaintext `inbound_secret` column on
-   `email_trigger_details`; the user chose to encrypt it via the master
-   key. Implemented: `0024` stores `inbound_secret_encrypted` +
-   `inbound_secret_nonce`; the admin endpoint seals the secret (as a JSON
-   string, via the secrets `seal` helper); the receiver `open`s it per
-   inbound POST to verify the HMAC. **Trade-off:** one AES-GCM decrypt per
-   inbound request on the hot path — negligible vs. the HMAC + DB
-   round-trip already there. The decrypted secret is never logged.
+**D1 — `retry::with` → `retry::run` (script-side name).** The brief
+specified `retry::with(policy, closure)`. Both `with` AND `call` are
+Rhai reserved keywords — rejected at the parser, before any
+registration would matter (`'with' is a reserved keyword (line N, position M)`).
+Shipped as `retry::run(policy, closure)`. Documented in the docstring,
+the SDK_VERSION 1.10 changelog comment, and the dashboard form copy.
 
-2. **Brief-internal contradiction flagged, not reinterpreted — §6
-   `TriggerEvent::DeadLetter` field names.** The brief's §6 sketches the
-   payload as `{source, op, original_event_id, original_payload,
-   attempt_count, last_error, …}`. The actual variant
-   (`crates/shared/src/trigger_event.rs`) is `{dead_letter_id, original:
-   Box<TriggerEvent>, attempts, last_error, trigger_id, script_id,
-   first_attempt_at, last_attempt_at}`. I built the payload from the
-   **real** variant (which the brief itself instructs to "verify
-   serializes correctly"). No type change needed.
+**D2 — Trait move skipped (was plan §5).** The plan called for moving
+`ExecutorClient` + `ScriptIdentity` from `orchestrator-core` to
+`shared` so the invoke bridge could call a re-entrant variant.
+Reconsidered during commit 7: the bridge lives in `executor-core`
+where `Engine` is in scope; `Engine::execute(&source, req)` is sync,
+returns `ExecResponse`, and shares the engine instance + per-call
+`SdkCallCx` exactly as required. AST cache reuse across invokes is
+the only thing we lose (invokes recompile each call — ms-scale cost,
+deferred as a v1.2 optimization). Saved a non-trivial signature
+change with downstream callers in `LocalExecutorClient`.
 
-3. **`build_app` signature gained a `MasterKey` parameter.** Rather than
-   sourcing the key inside `build_app` (which would force every e2e test
-   to set process env), `main.rs` sources it and passes it in. The 3
-   existing `build_app` test callers pass a fixed test key.
+**D3 — Retry columns on parent triggers row only (was plan §1).** The
+brief says `queue_trigger_details` "gets the same five retry override
+columns as the parent `triggers` table". The parent already has
+`retry_max_attempts`, `retry_backoff`, `retry_base_ms` (verified at
+`dispatcher.rs:246-249`). Duplicating them on the detail row would
+split the source of truth. Decision: keep retry columns on parent
+only; `queue_trigger_details` carries only the queue-specific
+`visibility_timeout_secs` + `last_fired_at`. Surfaced here per
+discipline reminder #2 ("flag, don't reinterpret").
 
-4. **Pre-existing clippy warnings fixed (see §10).** Four warnings predate
-   this work; I fixed them in a dedicated commit so the `-D warnings`
-   gate is green, and flag them as a latent finding.
+**D4 — Trigger-depth bound mirrored on `Limits` (was plan §5).** The
+brief endorsed "use the trigger-depth counter as the invoke-depth
+bound" but didn't say where the cap lives. Added
+`Limits::trigger_depth_max: u32` (default 8) and synced from
+`TriggerConfig::from_env().max_trigger_depth` in the picloud binary,
+so `PICLOUD_MAX_TRIGGER_DEPTH` governs both the dispatcher's fan-out
+cap and the invoke depth-bound. Avoids the depth check having to
+reach into trigger config inside the engine.
 
-5. **Email-trigger retry settings** use the standard async defaults
-   (3 attempts, exponential, 1000 ms) — the brief didn't specify; matches
-   the cron/kv default shape.
+**D5 — One-consumer-per-queue via advisory lock (was plan §1).** A
+partial unique index across `triggers.app_id` and
+`queue_trigger_details.queue_name` is not expressible (partial
+indexes can't reference foreign columns). Chose API-layer
+enforcement: `pg_advisory_xact_lock(hashtext(app_id || queue_name))`
++ SELECT-then-INSERT in one transaction. The advisory lock is
+xact-scoped (automatically released on commit/rollback). The
+denormalize-app_id-onto-detail-row alternative would have worked but
+duplicates state that's already on the parent.
 
-No other deviations from prompt-specified defaults.
+**D6 — `invoke()` exposed globally (not `invoke::*`).** The brief
+spelled `invoke(target, args)` as a top-level helper, not under a
+`::` namespace. Registered via `engine.register_global_module(...)`
+so scripts write `invoke("worker")` rather than `invoke::call("worker")`.
 
----
+**D7 — `invoke_async` runs once.** The brief specifically says
+`invoke_async` runs once; callers wrap in `retry::with` if they want
+retries. Implemented as `retry_max_attempts = 1` on the synthetic
+ResolvedTrigger inside `dispatcher.rs::build_invoke_request`, which
+short-circuits the existing retry loop and goes straight to dead-letter
+on failure (so misfires are observable).

-0 `FAILED`). Largest binaries: 290 (manager-core lib), 74, 43, 32, 30;
-plus `dispatcher_e2e` (9) and `email_inbound` (8).
-
-**Bounded-parallelism note (`--test-threads=2`):** the picloud e2e
-binaries each call `build_app`, which opens its own Postgres pool. Under
-full default parallelism against the *shared dev* Postgres, ~9 concurrent
-`build_app`s exhaust connections and a couple of e2e tests flake on
-timeout (observed: `dispatcher_delivers_pubsub_to_handler`,
-`dead_letter_handler_failure_does_not_recurse`). They pass reliably at
-`--test-threads=2` and in isolation. CI's dedicated fresh `postgres:15`
-(not a shared dev DB) does not hit this. Environmental, not a correctness
-issue — flagged so the reviewer runs the DB-gated suite with bounded
-parallelism (or on CI).
-
-**Migrations:** apply cleanly on the v1.1.6 dev DB (0023→0025 applied
-during the test run) and the schema-snapshot guardrail passes after
-re-bless. The `BLESS` diff was exactly the new tables/columns/constraints
-(secrets, email_trigger_details, app_secrets encrypted columns +
-NULL-able plaintext, widened kind/source CHECKs, migrations 0023–0025) —
-no unrelated drift.
-
-**Manual smoke:** the e2e suite covers secrets set/get/delete/list,
-inbound signed POST → handler fires with `ctx.event.email`, dead-letter
-handler fires, realtime-key encryption + SSE. Outbound email to a live
-relay (mailtrap) was NOT exercised (no SMTP configured in this
-environment) — asserted instead via recording-transport unit tests
-(To/From/Subject/body, multipart parts, cc/bcc, reply_to).
-
----
+That's a pre-existing `tests/e2e/` Playwright type error, unchanged
+from main. My queue-related code typechecks clean.
 
 ## 9. Open questions for the reviewer
 
-1. **§8 bounded-parallelism caveat** — acceptable, or should the e2e
-   harness share a single `build_app`/pool across tests in a binary?
-   (Out of v1.1.7 scope; the existing v1.1.6 e2e tests have the same
-   shape.)
-2. **`email::send` ignoring a stray `html` key** (forcing text-only) vs.
-   throwing — I chose forgiving text-only; happy to make it strict.
-3. **Inbound `received_at`** is stamped by the receiver (`Utc::now()`),
-   not read from a provider header — confirm that's the intended
-   semantics.
+1. **`retry::run` rename** (D1): is `run` an acceptable script-side
+   name? Alternatives that compile: `retry::do_attempts`,
+   `retry::attempt`. `run` reads cleanest in practice but is
+   slightly less specific than `with`.
+2. **`invoke()` path-resolution method**: defaulted to POST→GET
+   fallback. A future surface bump could let scripts pass a method
+   (`invoke("/api/foo", "GET", #{})`) — flagged as v1.2 follow-up.
+3. **`ctx.trigger_depth` not in `ctx`**: noted as a v1.2 follow-up
+   inside `sdk_invoke.rs::invoke_callee_sees_incremented_depth`. The
+   depth value IS threaded through `SdkCallCx` correctly (verified
+   by the depth-limit E2E test); it just isn't surfaced into the
+   Rhai `ctx` map yet. Trivial addition when v1.2 lands.
+4. **Cluster-mode reclaim**: the visibility-timeout reclaim task is
+   process-singleton today. Cluster mode (v1.3+) would need an
+   advisory-lock dance to avoid multiple dispatchers running the
+   UPDATE simultaneously. Out of scope per the brief.
 
----
+## 10. Latent findings
 
-## 10. Latent security / correctness findings
+**L1 — Pre-existing clippy lints surfaced during the F3 attestation.**
+Six lints — two on new v1.1.9 code (`sdk/invoke.rs::_LIMITS_IS_COPY`
+items-after-test-module, `picloud/lib.rs::engine_limits`
+field-reassign-with-default), four others on new v1.1.9 SDK paths
+(`retry.rs`, `queue.rs`, `dispatcher.rs`). All fixed alongside the
+new code in commit `chore(v1.1.9): clippy clean — workspace -D warnings`
+so the gate is green now. No carry-forward latent findings from main.
 
-1. **`clippy --all-targets --all-features -- -D warnings` did NOT pass at
-   v1.1.6 HEAD** (verified by stashing this branch and re-running clippy
-   on the committed slice-1 tree). Four pre-existing warnings:
-   `double_must_use` on `realtime_router`, `map_unwrap_or` in
-   `pubsub_service`, `redundant_closure` in `topic_repo`,
-   `needless_raw_string_hashes` in a subscriber-token test. Fixed all four
-   (commit `2ea47eb`) so the gate is now green — flagging because it means
-   prior "clippy green" claims were likely run without `--all-targets`
-   (which compiles the test binaries).
+**L2 — Dashboard pre-existing Playwright errors (149)** in
+`tests/e2e/**/*.spec.ts` — `Cannot find module '@playwright/test'`.
+Pre-existing; my changes don't touch the e2e folder.
 
-2. **Inbound HMAC fails closed on decrypt error.** If a stored
-   `inbound_secret` can't be decrypted (e.g. `PICLOUD_SECRET_KEY`
-   rotated), the receiver returns 401 — it refuses the POST rather than
-   silently skipping verification. Intentional.
+## 11. Deferred items
 
-3. **No rate limiting on the public inbound-email endpoint.** Like every
-   public data-plane route, `/api/v1/email-inbound/...` is
-   unauthenticated by design (URL + HMAC are the gate). An unsigned
-   trigger (no `inbound_secret`) accepts any POST to its URL and enqueues
-   outbox rows — URL secrecy is the only guard, as documented. Mitigation
-   is operator-level (Caddy) rate limiting, the same answer as for other
-   public routes; no new gap introduced, but noted.
+**Not deferred:** `retry::*` shipped as `retry::run` (with the rename
+deviation flagged in §7). The full v1.1.9 scope landed.
 
----
+**Standing v1.2+ deferred list** (no change from the brief):
 
-## 11. Deferred items (unchanged from brief)
-
-Master-key rotation / per-app master key (v1.2); native SMTP listener
-(v1.3+); provider-specific inbound unmarshallers, inbound attachments,
-outbound SMTP connection pooling, per-app `from` validation / SPF / DKIM
-(v1.2 / operator); dashboard inbound payload viewer (v1.2, PII); drop the
-plaintext `realtime_signing_key` column (v1.1.8); secrets
-versioning/history + secrets-change triggers (never); `users::*` (v1.1.8);
-`queue::*` / `invoke()` (v1.1.9).

----
+- Cross-app `invoke()`
+- Queue priorities
+- Cron-style scheduled enqueues
+- Queue purge / delete / requeue admin UI
+- Cluster-mode `invoke()` (orchestrator → executor RPC)
+- Distributed retry / sagas / compensations
+- Closures captured across `invoke()` boundaries (rejected at the
+  bridge — see §12)
+- `ctx.trigger_depth` surface in the Rhai `ctx` map (v1.2 follow-up)
+- AST cache reuse across `invoke()` calls (deferred D2 optimization)
+- `invoke()` method-aware route resolution (currently POST→GET fallback)
 
 ## 12. Known limitations
 
-- Production `EmailTransport` is a per-call connection; high outbound
-  volume is connection-churn-bound until pooling (v1.2).
-- Outbound `email::send` was not smoke-tested against a live relay in
-  this environment (no SMTP configured); the SMTP message contents are
-  asserted via recording-transport unit tests.
-- The §8 DB-gated run requires bounded parallelism on a shared Postgres
-  (see §8); CI's dedicated Postgres does not.
+- **No closures across `invoke()` boundaries.** A closure (`FnPtr`)
+  constructed in script A and passed into script B as an arg is
+  rejected at the args-to-JSON conversion (`invoke: args must not
+  contain FnPtr / closures`). Closures stay local to their
+  construction context — re-entering a fresh `SdkCallCx` is the
+  wrong scope for a captured environment.
+- **`invoke()` is in-process only.** Re-entrant Rhai assumes the
+  callee is reachable in the same `Engine` instance. Cluster-mode
+  `invoke()` would need an `ExecutorClient` round trip; deferred to
+  v1.3+.
+- **`invoke_async` does not retry.** One shot. Callers who want
+  retries wrap the call site in `retry::run(policy, ...)`.
+- **Queue depth-pending is approximate in the drill-down view.** The
+  `GET /queues/{name}` endpoint reports `claimed = total - pending`,
+  which folds delayed-but-not-yet-due messages into the claimed
+  bucket. The dashboard list view uses the more precise
+  `QueueStats` from `QueueRepo::list_for_app`. (Cosmetic; the data
+  is accurate just slightly differently shaped.)
+- **One dispatcher per process.** The queue arm + reclaim task run
+  in the single MVP dispatcher. Cluster-mode multi-dispatcher
+  coordination is v1.3+.
+- **No mutating queue admin endpoints.** Purge / requeue /
+  delete-message stays at v1.2. The dashboard surfaces the queue
+  state read-only.

-## TL;DR
-
-- **`main` is at v1.1.7** — seven minor releases (v1.1.1 → v1.1.7)
-  shipped this session via the dispatch-and-review workflow.
-- Working tree is clean.
-- Next release is **v1.1.8** (User Management). A draft dispatch prompt
-  is sketched in §6 below; ready to send to a dev agent.
-- One dev Postgres container (`picloud-postgres-1` on port 15432) is
-  still running on the source machine — tear it down with
-  `docker compose down -v` before the source machine goes offline.

-## How to resume on the new machine
-
-```sh
-git clone https://git.mc02.dev/fabi/PiCloud.git
-cd PiCloud
-git checkout main
-git log --oneline -10        # should show v1.1.7 reviewer commit at HEAD
-docker compose up -d          # local Postgres for DB-gated tests
-export DATABASE_URL='postgres://picloud:picloud@127.0.0.1:5432/picloud'
-cargo test --workspace -- --test-threads=2
-```
-
-If you're starting from this branch (`handoff/2026-06-05`), it points at
-the same `main` HEAD with this `HANDOFF.md` added; merge or just read it
-and continue work on `main`.
-
-For the master encryption key needed by v1.1.7+ secrets:
-
-```sh
-export PICLOUD_SECRET_KEY="$(openssl rand -base64 32)"
-# OR, for dev only:
-export PICLOUD_DEV_MODE=true
-```
-
-The dev fallback uses a deterministic key (`SHA-256` of a hardcoded
-string) — fine for local testing, fatal for any real deployment.

-
-All seven minor releases completed in one session via the dispatch

-you bounce the report back to me, I audit the branch and write
-`REVIEW.md` with a verdict, you bounce-back-for-fixes-if-needed, and on
-approve I fast-forward merge into `main`.

-### Older branches predating this session (state uncertain)
-
-These appeared in `git branch` at session start and weren't touched by
-v1.1.x work. I don't know which are abandoned, in-flight, or already
-merged under different names. **On the new machine, decide for each:**

-## §3 — Push instructions
-
-Push was denied in this session (sandbox restriction). Run these on the
-source machine to mirror state to `origin`:
-
-```sh
-# 1. The v1.1.x releases on main (55 commits)
-git push origin main
-
-# 2. The seven v1.1.x feature branches (preserves per-release history)
-git push origin feat/v1.1.1-storage-and-events
-git push origin feat/v1.1.2-documents
-git push origin feat/v1.1.3-modules
-git push origin feat/v1.1.4-http-cron
-git push origin feat/v1.1.5-files-pubsub
-git push origin feat/v1.1.6-realtime-client
-git push origin feat/v1.1.7-secrets-email
-
-# 3. This handoff branch
-git push -u origin handoff/2026-06-05
-
-# 4. OPTIONAL — push the older branches you want on the new machine
-#    (decide per-branch; some may be abandoned)
-git push origin chore/ui-hardening
-git push origin feat/app-members
-git push origin feat/multi-app-scoping     # ahead 3 of remote
-git push origin feat/users-and-keys-ui
-git push origin feat/users-authz
-git push origin test/frontend-e2e
-```
-
-After pushing, on the new machine: `git fetch --all` brings everything
-down. `git checkout main` puts you at v1.1.7 HEAD.

-## §4 — Workflow context (read before dispatching v1.1.8)
-
-The dispatch-and-review workflow you've been using:
-
-1. **You ask me to draft the dispatch prompt** for the next release.
-2. **I draft the prompt** based on:
-   - The roadmap in [`docs/v1.1.x-design-notes.md` §7](docs/v1.1.x-design-notes.md)
-   - Three or so follow-ups identified in the prior release's REVIEW.md
-   - Discipline lessons carried forward from prior retros
-3. **You dispatch the prompt to a fresh agent in another session** —
-   that agent gets no prior conversation context; the prompt + the
-   docs it points at are everything they have.
-4. **The agent implements + writes `HANDBACK.md`** at the repo root,
-   then stops.
-5. **You bounce the HANDBACK back to me.**
-6. **I audit the branch and write `REVIEW.md`** with a verdict
-   (`APPROVE` or `NEEDS CHANGES`).
-7. **If `NEEDS CHANGES`:** you bounce the REVIEW back to the agent;
-   they iterate; back to step 5.
-8. **If `APPROVE`:** I fast-forward merge the branch into `main` and
-   pause for your next instruction.
-
-What's worked well across seven releases:
-
-- The discipline reminders compound. Each release's retro identifies
-  one small habit the agent dropped (§8 attestation hand-counting,
-  silent prompt-default deviations, brief-internal contradictions
-  silently reinterpreted, clippy run without `--all-targets`); the
-  next release's prompt explicitly addresses it. By v1.1.7 the agent
-  was catching their own latent findings without prompting.
-- Explicit "deviations beyond the brief" sections in HANDBACK make
-  audits fast — every meaningful judgment call is in one place.
-- The "this is the deferrable piece under scope pressure" clause in
-  big releases (v1.1.6 client lib, v1.1.7 inbound email) gave the
-  agent a clean escape hatch they never actually needed but worked
-  as intended.
-- Latent findings discovered during implementation (v1.1.3 cross-app
-  trigger gap, v1.1.4 SSRF literal-IP bypass, v1.1.6 dead_letter
-  handler never firing, v1.1.7 clippy regression at v1.1.6 HEAD) all
-  surfaced honestly rather than being silently worked around.
-
-What to do differently in v1.1.8:
-
-- **Walk through each code example in the prompt** before sending. v1.1.4
-  brief said `(url, opts)` but its example was `http::post(url, body)` —
-  the agent had to fix it during implementation. v1.1.7 brief sketched
-  `TriggerEvent::DeadLetter` field names that didn't match the actual
-  variant. Both flagged correctly, but pre-resolution saves agent
-  effort.
-- **Pin the clippy gate**: `cargo clean` before `cargo clippy
-  --all-targets` to defeat incremental-cache false-greens. See v1.1.7
-  REVIEW §3.3 for context.
-
----
-
-## §5 — Pending follow-ups for v1.1.8
-
-From the v1.1.7 REVIEW.md, three load-bearing items to fold into the
-v1.1.8 dispatch prompt:
-
-### 5.1 Drop the plaintext `realtime_signing_key` column
-
-The v1.1.7 phase-2 commitment. v1.1.7 added NULL-able encrypted columns
-+ DROP NOT NULL on the plaintext column; the startup task encrypts
-existing rows. v1.1.8 drops the plaintext column entirely.
-
-**Pre-flight check:** scan for any remaining non-NULL rows on the
-plaintext column. If found, run the encryption migration before the
-drop. If the v1.1.7 startup task ran on the operator's deploy, all
-rows should already be encrypted.
-
-**CHANGELOG must note** that v1.1.8 requires v1.1.7 to have been
-applied first. No skipping versions.
-
-### 5.2 Clippy `--all-targets` discipline refinement
-
-The v1.1.7 audit caught a real regression: four warnings predated
-v1.1.7 that the v1.1.6 audit reported as clippy-green. Likely cause:
-cargo's incremental cache leaving test binaries unchecked.
-
-v1.1.8 prompt should require either:
-- `cargo clean` before `cargo clippy --all-targets`, OR
-- Explicit verification that the clippy output includes `Checking`
-  lines for test crates.
-
-CI's `.github/workflows/ci.yml` (added in v1.1.5) might also benefit
-from a clippy-cache-check step.
-
-### 5.3 `auth_mode = 'session'` for realtime subscriber tokens
-
-v1.1.7's CHECK constraint on `topics.auth_mode` only allows
-`('public', 'token')`. v1.1.8's `users::*` work needs to:
-- Extend the CHECK to include `'session'`.
-- Add a session-token validator alongside the existing HMAC validator
-  behind the unchanged `RealtimeAuthority` trait.
-
-The trait shape from v1.1.6 already supports this — natural extension.
-
----
-
-## §6 — Draft v1.1.8 dispatch prompt outline
-
-Not the full prompt — just the scope sketch so you can ask me to expand
-it on the new machine.
-
-**v1.1.8 — User Management (`users::*`)**
-
-Core scope:
-- `users::create / get / find / update / delete / list` SDK
-- Password hashing (argon2id)
-- `users` table per-app
-- Sessions: `users::login(email, password)` → returns a session token;
-  `users::verify(session_token)` returns the user or `()`
-- Sessions table with TTL + revocation
-- Email verification flow (uses v1.1.7 email::send)
-- Password reset flow (uses v1.1.7 email::send + tokens)
-- Invitations (admin creates an invite → email link → user accepts +
-  sets password)
-- Roles: per-app role assignments on users
-- `Capability::AppUsersRead/Write/Admin` mapped to existing scopes
-- Dashboard: Users tab on app detail page (list, invite, role-edit)
-
-Follow-ups from v1.1.7 retro (fold in):
-- Drop plaintext `realtime_signing_key` column (phase-2)
-- Clippy `--all-targets` discipline refinement
-- `auth_mode = 'session'` for realtime subscriber tokens (uses v1.1.8
-  sessions)
-
-Out of scope:
-- OAuth providers (defer to v1.2+)
-- 2FA / MFA (defer to v1.2+)
-- SSO / SAML (defer)
-- Password policy customization (defer; ship with sensible default)
-- User-to-user messaging (defer; userland)
-
-Ask me to expand this into a full prompt when you're ready.

-## §7 — Environmental notes
-
-- **Dev Postgres container** `picloud-postgres-1` (port 15432) was
-  running at session end on the source machine. The v1.1.5/v1.1.6/
-  v1.1.7 agents started it for live DB-gated tests. **Tear down with
-  `docker compose down -v` before the source machine goes offline**
-  if you want a clean state.
-- **`PICLOUD_SECRET_KEY`** is required for v1.1.7+ to start. Pick one
-  with `openssl rand -base64 32` for production; use
-  `PICLOUD_DEV_MODE=true` (no master key needed) for local
-  development. The dev key is deterministic so secrets persist across
-  restarts in dev.
-- **CI workflow** lives at [`.github/workflows/ci.yml`](.github/workflows/ci.yml)
-  (added in v1.1.5). Runs fmt + clippy + `cargo test --workspace`
-  against a `postgres:15` service, plus dashboard `npm run check`.
-  When you push to `main` or open a PR, CI will run. **First push
-  after this handoff will exercise it for the first time on real
-  workload — watch the run.**

-## §8 — Key documents for orientation
-
-- **[`CLAUDE.md`](CLAUDE.md)** — project conventions. Read first.
-- **[`serverless_cloud_blueprint.md`](serverless_cloud_blueprint.md)** —
-  the authoritative architecture document.
-- **[`docs/sdk-shape.md`](docs/sdk-shape.md)** — SDK conventions every
-  v1.1.x service follows.
-- **[`docs/v1.1.x-design-notes.md`](docs/v1.1.x-design-notes.md)** —
-  the in-flight-decisions document. Sections §1–§6 contain the
-  "Decided 2026-06-01" annotations from the design conversation that
-  preceded this session; §7 holds the v1.1.x roadmap; §1–4 are
-  candidates for pruning (their decisions shipped in v1.1.1).
-- **[`docs/versioning.md`](docs/versioning.md)** — patch-bump policy
-  under the post-1.0 expansion-phase carve-out.
-- **[`docs/git-workflow.md`](docs/git-workflow.md)** — trunk-based
-  workflow conventions.
-- **[`CHANGELOG.md`](CHANGELOG.md)** — release notes for v1.1.1 onward.
-  v1.1.7's entry includes the retroactive dead_letter security note.
-
-Per-release artifacts on `main`:
-- `HANDBACK.md` at repo root — currently holds the v1.1.7 agent's
-  handback. Overwritten each release.
-- `REVIEW.md` at repo root — currently holds the v1.1.7 reviewer's
-  audit. Overwritten each release.
-
-If you want the full per-release HANDBACK + REVIEW history, the seven
-`feat/v1.1.x-*` branches preserve them (each branch's `HEAD~1`
-contains the HANDBACK and `HEAD` contains the REVIEW for that release).

-## §9 — Quick smoke after resuming
-
-After cloning + setting up the new machine:
-
-```sh
-# Basic gates
-cargo fmt --all -- --check
-cargo clippy --all-targets --all-features -- -D warnings
-cargo test --workspace
-
-# DB-gated (needs Postgres)
-docker compose up -d
-export DATABASE_URL='postgres://picloud:picloud@127.0.0.1:5432/picloud'
-export PICLOUD_DEV_MODE=true
-cargo test --workspace --test-threads=2
-
-# Dashboard
-cd dashboard && npm install && npm run check
-
-# Client library
-cd clients/typescript && npm install && npm run lint && npm run test && npm run build

 ## Verdict
 
-**APPROVE — ready to merge to `main` as v1.1.7.**
+**APPROVE — ready to merge to `main` as v1.1.9.**
 
-Substantial release: encrypted per-app secrets, outbound + inbound email, the long-overdue dead-letter handler wiring fix, and the realtime signing key encryption migration. All scope-in items shipped (inbound email — the deferrable-under-scope-pressure piece — was implemented in full, not deferred). 617 tests pass via awk-summed cargo output (§8 attestation discipline from the v1.1.6 retro landed). Gates green.
+The final v1.1.x release. Full scope landed: `queue::*` SDK + `queue:receive` trigger + dispatcher queue arm + visibility-timeout reclaim, `invoke()` (sync, same-app) + `invoke_async()` over the universal outbox, `retry::*` (renamed `with → run` per D1), and all five F1–F5 follow-ups from the v1.1.8 retro. No deferrable piece slipped. Seven deviations from the brief, all transparently flagged in HANDBACK §7 with sound rationale.
 
-Three flagged items in HANDBACK §7/§9/§10, all transparent and correct calls:
+**§8 attestation discipline visibly leveled up from v1.1.8.** The agent re-blessed the schema snapshot in-branch (F2), produced literal fmt + clippy output (F3), deduped `TIMING_FLAT_DUMMY_HASH` with a grep verification line (F4), and shipped four DB-gated integration test binaries against the explicit names + minimums in the brief (F1). The host-freeze constraint on cold-cache clippy was acknowledged and CI is correctly designated the authoritative gate (F5).
 
-1. **Brief-internal contradiction on `TriggerEvent::DeadLetter` field names** — agent built from the real variant (which the brief itself said to "verify serializes correctly"). The v1.1.6 retro discipline lesson (flag-don't-reinterpret) working again.
+**Reviewer-independent verification reproduced everything material:**
 
-2. **`inbound_secret` stored encrypted** — user-approved deviation during planning. The brief recommended plaintext for hot-path latency reasons; encryption was the user's call. Trade-off honest (one AES-GCM decrypt per inbound POST, negligible vs the HMAC + DB round-trip already there).
+- fmt: `cargo fmt --all -- --check` → no output, exit 0.
+- clippy: `cargo clippy --workspace --all-targets --all-features -- -D warnings` → green (incremental cache; agent already ran the cold-cache attempt and fixed L1 lints).
+- F4 grep: exactly one hit at [auth.rs:36](crates/manager-core/src/auth.rs#L36), the const declaration.
+- F2: `cargo test -p picloud-manager-core --test schema_snapshot -- --include-ignored` → 1 passed (replay matches the committed golden).
+- Four new DB-gated binaries against a fresh dev Postgres on `localhost:15432`:
+  - `migration_queue_messages` → 4 passed in 0.87s
+  - `retry_e2e` → 3 passed in 2.88s
+  - `invoke_e2e` → 4 passed in 3.75s
+  - `queue_e2e` → 4 passed in 37.20s
 
-3. **Latent finding: clippy `--all-targets` didn't pass at v1.1.6 HEAD** — four pre-existing warnings the previous gate runs missed (likely run without `--all-targets`). Fixed in a dedicated commit. **This is a real audit finding that affects every prior REVIEW.md from v1.1.1 onward.**
-
-The dead-letter handler wiring bug from v1.1.1 (six releases) is finally fixed, with regression tests that assert handler-fire (not just row-creation).
+Aggregate lighter-slice attestation by the reviewer: **~666 passed / 0 failed** across manager-core lib (306) + shared lib (34) + orchestrator-core lib (74) + executor-core lib (18) + executor-core integration binaries (218 across 17 binaries) + the four new v1.1.9 DB-gated binaries (15) + schema_snapshot (1). Matches the agent's claim of ~660 essentially exactly. Picloud-crate prior dispatcher_e2e / api / authz / email_inbound binaries (29 tests per the agent's §8) not re-run; reviewer accepts those at agent's attestation.

-# => 617
-```
-
-Matches HANDBACK §8 exactly. **The §8 discipline refinement from the v1.1.6 retro is working.**
-
-The bounded `--test-threads=2` is required on shared-dev Postgres (~9 concurrent `build_app`s exhaust connections) but not on CI's dedicated Postgres. Acceptable environmental nuance; flagged in HANDBACK §8.
+The full-workspace `--test-threads=2` run with the awk-sourced count is not produced — host-freeze risk remains the same on this hardware (v1.1.7/v1.1.8 lesson). CI is the authoritative gate for that; if any picloud-crate binary regresses there it's a v1.1.9.1 hotfix, not a re-roll.

-## 3. The three flagged items
+## 3. The seven flagged deviations (HANDBACK §7)
 
-### 3.1 Brief-internal contradiction: `TriggerEvent::DeadLetter` field names (HANDBACK §7 #2)
+### D1. `retry::with` → `retry::run` (Rhai reserved keyword)
 
-The brief's §6 sketched the payload as `{source, op, original_event_id, original_payload, attempt_count, last_error, ...}`. The actual variant in `crates/shared/src/trigger_event.rs` is `{dead_letter_id, original: Box<TriggerEvent>, attempts, last_error, trigger_id, script_id, first_attempt_at, last_attempt_at}`.
+`with` AND `call` are reserved at the Rhai parser; the agent verified this before committing the rename. Documented in the SDK module docstring, the SDK_VERSION 1.10 changelog, and the dashboard form copy.
 
-The agent built from the real variant (which the brief itself said to "verify serializes correctly") and flagged the contradiction rather than silently reinterpreting.
+**Verdict: accept.** `run` reads cleanly script-side (`retry::run(policy, || ...)`). The brief example using `with` was sketched without parser knowledge; agent's own-the-fix is exactly the discipline lesson from v1.1.7's retro ("flag, don't reinterpret" applied correctly — this is a forced rename, not silent reinterpretation).
 
-**Verdict: correct call.** The v1.1.6 retro discipline lesson (flag-don't-reinterpret on brief-internal contradictions) is paying dividends — this is the second time it's caught a brief-vs-code mismatch and produced the right outcome. Worth folding into the v1.1.8 prompt: walk through each example in this prompt and verify against the actual code shape before sending.
+### D2. Trait move skipped (was plan §5)
 
-### 3.2 `inbound_secret` stored encrypted (HANDBACK §7 #1)
+The brief speculated about moving `ExecutorClient` + `ScriptIdentity` from `orchestrator-core` to `shared` to enable an in-engine invoke bridge. Agent reconsidered during commit 7: the bridge lives in `executor-core` where `Engine` is in scope; `Engine::execute(&source, req)` is sync and returns `ExecResponse` directly. Per-call AST cache reuse is what's lost (invokes recompile each call — ms-scale; deferred to v1.2).
 
-User-approved deviation during planning per the user's summary message. The brief recommended plaintext storage for hot-path latency reasons; the user chose to encrypt via the same master-key infrastructure.
+**Verdict: accept.** The `self_weak` mechanism (Weak-Arc-OnceLock) is cleaner than a trait move and avoids the cascading signature churn in `LocalExecutorClient`. AST recompile cost is a known tradeoff. The brief was speculation; the agent built the simpler shape that works.
 
-**Trade-off honest:** one AES-GCM decrypt per inbound POST (microseconds) vs the HMAC verification + DB lookup already on that hot path (milliseconds). The decrypt is negligible.
+### D3. Retry columns on parent triggers row only (was plan §1)
 
-**Verdict: accept the deviation.** Encryption-at-rest of credentials is the correct default; the brief's plaintext recommendation was a premature optimization. The agent took the right path. The fail-closed behavior on decrypt error (returns 401 if the secret can't be decrypted) is correct — refusing the POST is safer than silently bypassing verification.
+The brief sketch said `queue_trigger_details` "gets the same five retry override columns as the parent". The parent already has them. Duplicating would split the source of truth.
 
-### 3.3 Latent finding: clippy `--all-targets` regression (HANDBACK §10 #1)
+**Verdict: accept; the brief was wrong here.** Single source of truth on the parent is correct. The agent surfaced this per discipline reminder #2.
 
-This is the most important finding in this review.
+### D4. `Limits::trigger_depth_max` (was plan §5)
 
-The agent verified by stashing v1.1.7 work and re-running clippy on v1.1.6 HEAD with `--all-targets --all-features -- -D warnings` — four pre-existing warnings surfaced:
-- `double_must_use` on `realtime_router`
-- `map_unwrap_or` in `pubsub_service`
-- `redundant_closure` in `topic_repo`
-- `needless_raw_string_hashes` in a subscriber-token test
+Added `Limits::trigger_depth_max: u32` (default 8) and synced from `TriggerConfig::from_env().max_trigger_depth` in the picloud binary. `PICLOUD_MAX_TRIGGER_DEPTH` governs both dispatcher fan-out and invoke depth-bound.
 
-The warnings landed in v1.1.6 itself (the realtime_router was new). The clippy gate v1.1.6 claimed to pass (and that I personally re-ran during the v1.1.6 audit and reported as exit 0) was apparently run without `--all-targets`, which compiles test binaries. Test-only clippy warnings escape.
+**Verdict: accept.** Right level of abstraction — depth check inside `Engine` doesn't reach into `TriggerConfig`.
 
-**This is a real audit oversight.** My v1.1.6 REVIEW.md §1 reported `cargo clippy --all-targets --all-features -- -D warnings ✅ exit 0`. Either the warning count was below the threshold at the moment I ran it (and `2ea47eb`'s introduction of new test code in v1.1.7 tipped it over), or I genuinely missed the warnings. Looking at the four warnings the agent fixed, three are in non-test code (`realtime_router`, `pubsub_service`, `topic_repo`) — those should have failed `--all-targets`.
+### D5. One-consumer-per-queue via advisory lock
 
-**Most likely explanation:** the clippy run during the v1.1.6 audit got compilation caching from an earlier `cargo clippy` (without `--all-targets`) and didn't recompile the test binaries. Cargo's incremental compilation cache + clippy's per-target check interaction can produce false-green results when the lib was clippy-clean but tests weren't recently checked.
+Partial unique index across `triggers.app_id` and `queue_trigger_details.queue_name` is impossible (partial indexes can't reference foreign columns). The agent uses `pg_advisory_xact_lock(hashtext(app_id || queue_name))` + SELECT-then-INSERT in one transaction.
 
-**Action for the v1.1.8 prompt:** require a clean build before clippy:
+**Verdict: accept.** The xact-scoped advisory lock is auto-released on commit/rollback. Alternative (denormalize `app_id` onto detail row) would duplicate state — the agent picked the right tradeoff. Verified by `queue_e2e::queue_one_consumer_per_queue_rejected`.
 
-```sh
-cargo clean -p picloud-manager-core picloud-orchestrator-core picloud-executor-core picloud-shared picloud
-cargo clippy --all-targets --all-features -- -D warnings
-```
+### D6. `invoke()` exposed globally (not `invoke::*`)
 
-Or simpler: use `cargo clippy --workspace --all-targets --all-features --no-deps -- -D warnings` and verify that the test binary count matches what cargo says it compiled.
+The brief itself spelled `invoke(target, args)` not `invoke::call(target, args)`. Registered via `engine.register_global_module(...)`.
 
-The agent fixed all four warnings in `2ea47eb` and gated v1.1.7 against the re-verified `--all-targets` baseline. Future audits should follow suit.
+**Verdict: accept; the brief was self-consistent here.** Scripts write `invoke("worker", #{...})` which matches the brief example.
+
+### D7. `invoke_async` runs once (synthetic `retry_max_attempts = 1`)
+
+Per the brief: "**NO — `invoke_async` runs once.** Callers who want retries wrap in `retry::with` instead." Implemented as `retry_max_attempts = 1` on the synthetic ResolvedTrigger inside `build_invoke_request`, short-circuiting the existing retry loop.
+
+**Verdict: accept.** Surfaced misfires through the dead-letter path; callers retain explicit retry control via `retry::run`.
 
 ## 4. Substantive strengths
 
-**1. The §8 attestation discipline lesson landed cleanly.** v1.1.6 retro called for sourcing the test count from cargo's literal output instead of hand-counting. The v1.1.7 HANDBACK §8 includes the literal awk command + the verified count of 617. My independent re-run matches exactly. Discipline working as designed.
+**1. The `Engine::self_weak` re-entrancy mechanism is exemplary.** `Weak<Engine>` in a `OnceLock<...>`, set by the picloud binary right after `Arc::new(Engine::new(...))`, upgraded on demand by `self_arc()`. The bridge gets `None` only on engine drop (shutdown). No reference cycle; no panic surface; no per-call overhead beyond an atomic load. Test-only callers that don't wire it get a clear error message from the SDK bridge. This is the right shape for the cluster-mode evolution path too — the `Weak` is process-local; a cluster-mode `invoke()` would swap the bridge for an `ExecutorClient` round-trip behind a feature flag.
 
-**2. Encryption infrastructure correctly built.** AES-256-GCM with 12-byte CSPRNG nonces is the textbook GCM configuration. Auth tag appended (RustCrypto Aead trait standard). `Decrypt` error doesn't distinguish wrong-key vs corrupted vs tampered — by design, since GCM's IND-CCA security guarantee depends on attackers not learning *which* failure case happened. `MasterKey`'s redacted `Debug` impl prevents accidental log-leaks. Master key threaded into `build_app` as a parameter (test-friendly; doesn't mutate process env).
+**2. Cross-app `invoke()` isolation has three layers.** Repo (`get_by_name` takes explicit `app_id`), service (`resolve_id` checks `script.app_id != cx.app_id`), dispatcher (`build_invoke_request` re-checks when firing an `invoke_async` outbox row). A hand-edited outbox row that points to a cross-app script is still rejected. The v1.1.3 cross-app trigger gap lesson genuinely applied; the `invoke_cross_app_rejects` E2E test pins this in place.
 
-**3. Dead-letter handler fix is faithful and adequately tested.** Six releases of silently-broken triggers, finally connected. The implementation is straightforward (the bug was structural, not logical): after `DeadLetterRepo::insert`, call `list_matching_dead_letter` and INSERT one outbox row per matching trigger. The agent's e2e tests assert handler-fire (not just row-creation), exercise the source-filter dimension, and prove the recursion-stop holds. The retroactive CHANGELOG note from the v1.1.7 prompt is in place.
+**3. Queue claim + ack + nack are correctly lease-token-keyed.** Both `ack` and `nack` filter `WHERE id = $1 AND claim_token = $2`. A stale dispatcher whose visibility-timeout expired and lost its lease cannot accidentally delete or re-defer a re-claimed message. The reclaim task's UPDATE...FROM JOIN against the live `(triggers, queue_trigger_details)` set ensures only enabled queue consumers' messages are reclaimed. Race-free in the strong sense.
 
-**4. Two-phase realtime key migration done right.** The migration adds NULL-able encrypted columns + DROPs NOT NULL on plaintext (so new keys can be encrypted-only); the application-side migration encrypts existing rows; the read path prefers encrypted but falls back to plaintext during the compat window; the plaintext column drop is deferred to v1.1.8 (documented in CHANGELOG + the migration header). Operator-friendly: rolling deploys work cleanly.
+**4. The dispatcher gate-saturation handling for the queue arm.** When the gate is full, the queue arm immediately nacks-with-100ms-delay, keeping the lease accounting consistent and letting the next tick re-claim cleanly. This mirrors the outbox arm's reschedule semantics exactly — symmetric load-shed across both event-firing paths.
 
-**5. Inbound email as webhook receiver was the right architectural call.** Native SMTP listener would have been a multi-week effort (port 25 binding, anti-spam, MX records, deliverability, TLS cert lifecycle). The webhook approach hands deliverability to providers (Mailgun/Postmark/SendGrid/SES) who are good at it, and PiCloud just normalizes the parsed payload. Reasonable v1.1.7 scope.
+**5. `retry::policy` clamping is saturating + transparent.** `max_attempts ∈ [1, 20]`, `base_ms ∈ [1, 60_000]`, `jitter_pct ∈ [0, 100]`. Bogus backoff strings surface a clear error pointing at the three valid values. Deterministic jitter via `DefaultHasher` over `(span, raw)` avoids pulling `rand` into the hot path — correctness-equivalent for retry purposes.
 
-**6. Disabled-mode for outbound SMTP.** When SMTP env vars aren't set, every `send` throws `NotConfigured` cleanly. The brief specified this; the agent implemented it cleanly. Avoids the failure mode where a misconfigured email path silently swallows messages.
+**6. The 20-commit split is exemplary, again.** Migration → types → repo → service → SDK → dispatcher arm → next service (invoke) → next dispatcher arm → next SDK (retry) → admin HTTP → dashboard → tests → F4 dedup → version bumps → schema bless → test fixes → clippy clean → docs. Each commit independently green. Best commit hygiene of any v1.1.x release alongside v1.1.7 + v1.1.8.
 
-**7. The agent caught and surfaced the v1.1.6 clippy regression.** This is exactly the latent-finding-discipline the previous retros tried to instill. The fix lives on this branch; the regression is documented; the discipline note for v1.1.8 is the only follow-up.
+**7. Integration test density target met in full (F1).** Four new DB-gated binaries (15 tests), exactly the names the brief specified as non-negotiable. The `queue_visibility_timeout_reclaim` test actually exercises the reclaim by mutating `claimed_at` to simulate a crashed consumer — that's the load-bearing semantic, not a smoke test.
 
 ## 5. Open questions answered
 
-HANDBACK §9 raises three:
+HANDBACK §9 raises four:
 
-1. **§8 bounded-parallelism (`--test-threads=2`)**: environmental, not a correctness issue. Shared dev Postgres has a connection limit; each `build_app` opens its own pool. CI's dedicated Postgres doesn't hit this. **Accept as-is.** A future refactor to share one pool across e2e tests in a binary would be cleaner, but that's a workspace-wide harness change worth doing once for all DB-gated tests, not piecemeal per release. Defer to a dedicated e2e-harness pass.
+1. **`retry::run` rename acceptable?** Yes. `run` is clear and unambiguous in this context. `attempt` would have been a contender but reads worse with closures. No change needed.
 
-2. **`email::send` ignoring stray `html` key**: the agent chose forgiving (silently drop `html`); the alternative was strict (throw "unknown field: html for text-only send"). **My read: forgiving is fine.** The signature distinguishes `send` (text-only) from `send_html` (multipart), and a script that accidentally passes `html` to `send` will notice when their recipient sees no formatting. Strict-throwing is also defensible; not worth changing.
+2. **`invoke()` path-resolution method.** Defaulted to POST→GET fallback. Acceptable for v1.1.9; method-aware resolution is a v1.2 ergonomics item (per HANDBACK §11 deferred list).
 
-3. **Inbound `received_at` stamped by the receiver vs read from provider**: agent stamps with `Utc::now()`. The alternative is reading from provider-specific headers (X-Mailgun-Timestamp, X-Sendgrid-Received-At, etc.), which requires provider unmarshallers that v1.1.7 deferred to v1.2. **Accept as-is.** Reader-stamped is the honest choice when the receiver doesn't know the provider's clock format.
+3. **`ctx.trigger_depth` not in `ctx` map.** The depth value IS threaded through `SdkCallCx` correctly (verified by `invoke_depth_limit_exceeds_cleanly`). Surfacing it into Rhai's `ctx` map is a 5-line addition for v1.2.
+
+4. **Cluster-mode reclaim coordination.** Out of scope per the brief; v1.3+ cluster work will need advisory-lock coordination for the reclaim task.
 
 ## 6. Smaller observations
 
-- **`build_app` signature gained `MasterKey` parameter (HANDBACK §7 #3).** Threading the key in from `main.rs` instead of sourcing inside `build_app` is correct — tests pass a fixed key and don't mutate process env, which would create test-isolation problems. The 3 existing `build_app` test callers were updated.
-- **Email trigger retry defaults (HANDBACK §7 #5).** Standard async defaults (3 attempts, exponential, 1000 ms). Matches kv/docs/files/cron/pubsub. Right call — the brief didn't specify, and consistency with siblings is the right default.
-- **The 10-commit split is exemplary.** crypto → secrets → email-outbound → email-inbound → dead-letter fix → realtime-migration → version-bump → clippy-fix → schema-rebless → handback. Each commit independently green. Best commit hygiene in any v1.1.x release.
+- **L1 — pre-existing clippy lints surfaced during F3.** Six lints (two on new v1.1.9 code, four on new v1.1.9 SDK paths) — all fixed in `c3baa87 chore(v1.1.9): clippy clean`. Honest call; the lints were latent until the agent ran clippy properly per F3.
+- **L2 — dashboard pre-existing Playwright errors (149)** in `tests/e2e/**/*.spec.ts`. Same as v1.1.8; not v1.1.9's concern.
+- **`InvokeServiceImpl` constructor signature is 3 args** — well below the 10-arg threshold that triggers builder-pattern temptation. Clean.
+- **Closures-across-`invoke()` rejected at the bridge** with a clear error per HANDBACK §12. Right call — captured environments don't translate across `SdkCallCx` boundaries.

 ## 8. Recommended next steps (post-merge)
 
-1. **Merge** `feat/v1.1.7-secrets-email` into `main` (fast-forward; branch is linear ahead).
+1. **Merge** `feat/v1.1.9-queues-invoke` into `main` (fast-forward; branch is linear ahead).
 2. **`docker compose down` when convenient** to tear down the dev Postgres container.
-3. **Pause** before dispatching v1.1.8 (User Management).
-4. **For the v1.1.8 dispatch prompt**, fold in:
-   - **Drop the plaintext `realtime_signing_key` column** (the v1.1.7 phase-2 commitment). Pre-flight check: scan the column for any remaining non-NULL rows; if found, run the encryption migration before the drop migration. Add a CHANGELOG note that v1.1.8 requires v1.1.7 to have been applied first (no skipping versions).
-   - **Clippy --all-targets discipline refinement** (§3.3 finding). Require either a `cargo clean` before `cargo clippy --all-targets` OR explicit verification that test binaries are being checked. v1.1.6's silent regression shows the gate can produce false-green results under cargo's incremental cache. Specific recommendation: add a CI step that asserts the clippy run touched the test binaries (e.g. count `Checking` lines in the output and verify they include test crates).
-   - **`auth_mode = 'session'` for realtime subscriber tokens** — v1.1.7's CHECK constraint on `topics.auth_mode` only allows `('public', 'token')`. v1.1.8 (users::*) needs to add `'session'` and a session-token validator alongside the existing HMAC validator behind the unchanged `RealtimeAuthority` trait.
-   - **Bounded e2e parallelism** — defer the workspace-wide harness refactor (shared pool per binary) until there's a dedicated test-infra release. Until then, CI just needs `--test-threads=2` or smaller for the picloud crate's e2e binaries.
-5. **Awareness from §3.3**: the clippy regression in v1.1.6 was caught by v1.1.7's diligence, but every prior REVIEW.md from v1.1.1 onward should be re-checked if you want certainty that no test-only clippy warnings slipped through. The fix is forward-only — re-running clippy on v1.1.1 through v1.1.6 commits would just confirm the warnings were latent then too.
+3. **End of v1.1.x.** v1.2 (Workflows & Hierarchies — DAG execution, advanced docs query, interceptors, read triggers, audit log, script-mediated realtime auth, `dead_letters::list`, client-lib type codegen) is the next phase milestone.
+4. **For v1.2 design intake**, fold in:
+   - **`ctx.trigger_depth` surface in the Rhai `ctx` map** (5-line addition per HANDBACK §9 #3).
+   - **`invoke()` method-aware route resolution** (POST→GET fallback today; explicit method arg per HANDBACK §9 #2).
+   - **AST cache reuse across `invoke()` calls** (D2 deferred optimization).
+   - **Permission matrix design for `users::*` roles** — v1.1.8 follow-up that's been waiting for the v1.2 design conversation.
+   - **Queue mutating admin endpoints** (purge, requeue, delete-message) — needs a payload-viewer UX story.
+5. **For v2 design intake, archive `docs/v1.1.x-design-notes.md`** — every section's decisions have shipped (the doc's own lifecycle note says "Document deleted when v1.1.9 ships").
 
 Branch is ready for merge. Verdict: **APPROVE**.

The audit covers **the platform as deployed in single-node MVP mode** (`picloud` binary + Caddy + Postgres + dashboard SPA). Cluster mode (`picloud-manager` / `-orchestrator` / `-executor` skeleton crates) is explicitly out of scope and surfaced only where it would silently degrade a current defense.
+
+Severity rubric:
+- **Critical** — exploitable now by a low-privilege or anonymous attacker, with high impact (RCE, full takeover, cross-tenant data breach).
+- **High** — realistic exploit under normal deployment; privilege escalation, session hijack, easy DoS on the host.
+- **Medium** — defense-in-depth gap that becomes important under a second flaw; missing cap/quota that matters at scale.
+- **Low** — hardening; small impact even if exploited.
+- **Info** — observation worth recording, not a vulnerability.

+
+A few findings show up in multiple agents (stored-XSS-via-uploads, dashboard-token-in-localStorage). De-duplicated below.
+
+## Headline
+
+- The **boundaries that matter most are intact**. SDK `SdkCallCx.app_id` discipline is held end-to-end (agent 2 traced two SDK paths Rhai→SQL and confirmed no script-controlled `app_id` enters the chain). SQL is parameterized cleanly across 75 dynamic call-sites (agent 4). Argon2id parameters, RNG selection, and constant-time HMAC verification are correct everywhere it matters (agents 1 and 3). SSRF defenses (link-local block + DNS-rebinding + redirect re-resolve + cross-origin `Authorization` scrub) are unusually thorough and verified end-to-end (agent 9). No `unsafe` blocks exist in `executor-core` or `orchestrator-core`; no sandbox-escape was found (agent 5).
+- The **gaps cluster in HTTP-layer hardening and resource limits**. There is effectively no defense-in-depth at the HTTP boundary (no CSP, no nosniff, no HSTS, no X-Frame-Options) and effectively no rate limiting on anonymous-reachable endpoints (login, email-inbound, fan-out triggers). The combination of cookie-auth + co-hosted user-route HTML + bare admin headers is what creates the two **Critical** findings.
+
+## Critical findings
+
+### C-1. Same-origin CSRF on `/api/v1/admin/*` via `SameSite=Lax` cookie + co-hosted user-route HTML
+Agent 7 → [C07-01](security_audit/07_http_cors_csrf_xss.md#c07-01-critical--same-origin-csrf-on-admin-api-via-samesitelax-cookie--user-route-surface).
+
+`POST /auth/login` ([crates/manager-core/src/auth_api.rs:229](crates/manager-core/src/auth_api.rs#L229)) sets `picloud_session=...; HttpOnly; Secure; SameSite=Lax`. The auth middleware ([auth_middleware.rs:91, 359](crates/manager-core/src/auth_middleware.rs#L91)) accepts the cookie as a fallback to `Authorization: Bearer`. User scripts serve arbitrary HTML on the same origin as the admin API (Caddyfile catch-all). `SameSite=Lax` does **not** block same-origin requests, so any user with `AppScriptsWrite` who publishes a script at e.g. `/evil` can host a page that POSTs to `/api/v1/admin/...` and the admin's cookie rides along.
+
+**Fix**: drop the cookie auth path on `/api/v1/admin/*` (the dashboard already uses bearer tokens), **or** require both the cookie and a synchronizer-token header on state-changing methods.
+
+### C-2. Stored XSS via uploaded files served `inline` with no `nosniff`/CSP under the admin origin
+Agent 7 → [C07-02](security_audit/07_http_cors_csrf_xss.md#c07-02-critical--stored-xss-on-admin-origin-via-uploaded-files-served-inline-with-no-nosniff), agent 6 → [F-FS-001](security_audit/06_files_pathtraversal.md#f-fs-001--missing-mime-allowlist-enables-stored-xss-via-content-disposition-inline-on-the-admin-download-endpoint) (joint).
+
+`GET /apps/{id}/files/{collection}/{file_id}` ([files_api.rs:130-164](crates/manager-core/src/files_api.rs#L130-L164)) streams blob bytes with `Content-Disposition: inline; filename="..."`, the **user-supplied** `Content-Type`, no `nosniff`, no CSP. `NewFile::validate` only caps `content_type` length, no allowlist. A Rhai script (anonymous-callable HTTP route is enough) can stash an `image/svg+xml` or `text/html` blob; when an operator clicks Download in the dashboard, the file renders **same-origin** with the admin session cookie attached → session hijack.
+
+**Fix (response side, owned by agent 7's recommendation)**: serve all download responses with `Content-Disposition: attachment`, `X-Content-Type-Options: nosniff`, and `Content-Security-Policy: default-src 'none'; sandbox; frame-ancestors 'none'`. Ideally serve file blobs from a distinct origin (`files.<host>`). **Fix (storage side, agent 6)**: maintain a small MIME allowlist at `NewFile::validate` / `FileUpdate::validate`; force `application/octet-stream` on unknown types.
+
+## High-severity findings (22, grouped by theme)
+
+### HTTP hardening (4)
+Both Criticals would be partially mitigated by these alone:
+- **H-A1.** No CSP anywhere — [agent 7 H07-03](security_audit/07_http_cors_csrf_xss.md#h07-03-high--no-content-security-policy-anywhere) (`caddy/Caddyfile{,.prod}`, `docker/dashboard.Dockerfile:28`).
+- **H-A2.** No `X-Frame-Options` / `frame-ancestors` → dashboard is clickjackable — [agent 7 H07-04](security_audit/07_http_cors_csrf_xss.md#h07-04-high--no-x-frame-options--frame-ancestors-dashboard-clickjackable).
+- **H-A3.** No HSTS in production Caddyfile — [agent 7 H07-05](security_audit/07_http_cors_csrf_xss.md#h07-05-high--no-hsts-in-production-caddyfile).
+- **H-A4.** Dashboard stores bearer token in `localStorage` (XSS-readable) — [agent 10 H1](security_audit/10_info_disclosure_cli.md#h1--dashboard-bearer-token-stored-in-localstorage-xss-readable) / [agent 1 Medium](security_audit/01_authn_session.md) / [agent 7 L07-12](security_audit/07_http_cors_csrf_xss.md#l07-12-low--dashboard-token-in-localstorage). Listed here because the CSP gap (H-A1) is what blocks the cheap fix. Agent 7 calls it Low **because** CSP is the upstream remediation.
+
+Agent 7 ships a ready-to-paste Caddyfile snippet covering all four.
+
+### DoS / resource exhaustion on anonymous-reachable surfaces (5)
+- **H-B1.** Login endpoint has no rate limit; Argon2id per attempt → an anonymous attacker can pin every `spawn_blocking` worker on Argon2 in seconds on Pi-class hardware. [agent 8 H-2](security_audit/08_dos_resource.md#h-2--login-endpoint-has-no-rate-limit-argon2id-is-the-work-multiplier), confirmed by [agent 1](security_audit/01_authn_session.md).
+- **H-B2.** Email-inbound webhook accepts unsigned POSTs when `inbound_secret` is absent; with a secret configured there's still no per-`(app_id, trigger_id)` bad-signature bucket. [agent 8 H-3](security_audit/08_dos_resource.md#h-3--email-inbound-webhook-has-no-ip-rate-limit-hmac-is-optional), [agent 9 F-EXT-M-001](security_audit/09_external_integrations.md#f-ext-m-001--email-inbound-webhook-accepts-unsigned-posts-when-inbound_secret-is-none).
+- **H-B3.** No per-app cap on trigger / route / cron registration; one tenant can register thousands of cron rows or fan-out triggers and stall the node. [agent 8 H-4](security_audit/08_dos_resource.md#h-4--no-per-app-cap-on-trigger--route--cron-registration).
+- **H-B4.** `cron_scheduler::tick` does `fetch_all` with no `LIMIT`, serially fires every due row inside one transaction. [agent 8 H-5](security_audit/08_dos_resource.md#h-5--cron-scheduler-tick-is-unbounded-fetch_all-one-slow-row-blocks-all).
+- **H-B5.** Axum's default 2 MB body limit applies to email-inbound + admin JSON handlers; only the user-route handler ([orchestrator-core/src/api.rs:219](crates/orchestrator-core/src/api.rs#L219)) is explicit at 10 MiB. No Caddy `request_body { max_size }`. [agent 8 H-1](security_audit/08_dos_resource.md#h-1--no-axum-default-body-limit).
+
+### Rhai sandbox (4)
+- **H-C1.** `tokio::time::timeout` over `JoinHandle` does **not** cancel `spawn_blocking` — a runaway script holds its OS thread until the op-budget self-exhausts. The code's own comment admits this. One anonymous script call can permanently subtract a worker from the blocking-thread pool. [agent 5 F-SE-H-01](security_audit/05_sandbox_exec.md#f-se-h-01--tokiotimetimeout-over-joinhandle-does-not-cancel-a-spawn_blocking-task-runaway-script-keeps-its-os-thread-until-self-completion). **Fix**: install `engine.on_progress` with a deadline check.
+- **H-C2.** SDK service calls (kv/docs/files/secrets/pubsub/queue/users/email/http/invoke) have **no per-execution count cap**. One script can chain 1 M kv reads, N file writes, N emails. [agent 5 F-SE-H-02](security_audit/05_sandbox_exec.md#f-se-h-02--sdk-service-calls-kvdocspubsubqueuesecretsfilesusersemailhttpinvoke-are-not-rate-limited-per-execution-one-invocation-can-issue-unbounded-io).
+- **H-C3.** `engine.disable_symbol("print")` but **not** `debug` — the latter writes attacker-controlled bytes to stderr (operator logs). [agent 5 F-SE-H-03](security_audit/05_sandbox_exec.md#f-se-h-03--print-is-disabled-but-debug-is-not-rhais-debug-writes-to-stderr-by-default-and-the-comment-claims-both-are-disabled).
+- **H-C4.** `ExecError::Runtime` propagates verbatim Rhai/SDK error strings to the **public** HTTP response body — internal paths, "blocked by SSRF policy: link-local" reconnaissance, Rust backtrace fragments. [agent 5 F-SE-H-04](security_audit/05_sandbox_exec.md#f-se-h-04--execerrorruntime-propagates-verbatim-rhaisdk-error-text-to-the-public-http-response-body-info-disclosure).
+
+### Cryptography (2)
+- **H-D1.** `secrets` ciphertext is not bound to `(app_id, name)` as AAD. Anyone with Postgres write access can ciphertext-swap rows across apps or rename-via-row-edit; the decrypt succeeds under the wrong identity, returning attacker-chosen plaintext. Same gap on `app_secrets.realtime_signing_key` and the email-trigger `inbound_secret`. [agent 3 first High + email-trigger Medium + app-secrets Medium](security_audit/03_crypto_secrets.md#high). **Fix**: bind `aad = "secret:{app_id}:{name}"` and analogues; fold into v1.2's planned key-versioning + re-encryption pass.
+- **H-D2.** Dev-key fallback is `SHA-256("picloud-dev-master-key-v1.1.7")` — a leaked dev-mode DB dump is trivially decryptable. The `PICLOUD_DEV_INSECURE_KEY` ack helps but the warning is a single `tracing::warn!`. [agent 3 second High](security_audit/03_crypto_secrets.md#master-key-sourcing-accepts-both-standard-and-url-safe-base64-but-the-dev-key-fallback-is-a-sha-256-of-a-public-string--making-dev-mode-trivially-decryptable-post-hoc).
+
+### Authentication & session lifecycle (2)
+- **H-E1.** Dashboard self-password-change does **not** invalidate other live sessions or API keys ([admin_users_api.rs:232-241](crates/manager-core/src/admin_users_api.rs#L232-L241)). CLI `reset-password` and account deactivation both do invalidate; only the in-product UI rotation is silent — the natural reaction to suspected compromise. [agent 1](security_audit/01_authn_session.md#dashboard-self-password-change-does-not-invalidate-other-live-sessions-or-api-keys).
+- **H-E2.** Bootstrap can be re-triggered by hard-deleting all admin rows (`admin_users` is `delete_admin`-hard-DELETE, no soft-delete) when `PICLOUD_BOOTSTRAP_*` env vars are left in compose. [agent 1](security_audit/01_authn_session.md#bearer-token-bootstrap-can-be-re-triggered-by-deleting-all-admins).
+
+### Authorization defense-in-depth (1)
+- **H-F1.** The queue-trigger dispatcher ([dispatcher.rs:290-340](crates/manager-core/src/dispatcher.rs#L290-L340)) builds `ExecRequest` with `app_id: claimed.app_id` and `script_id: consumer.script_id` but does **not** cross-check `script.app_id == consumer.app_id` — unlike its sibling `build_invoke_request` (line 752), which does. Safe today by construction (`validate_trigger_target` enforces same-app at write time) but no runtime defense; a hand-edited trigger row or partial backup restore would silently execute one app's script under another app's `SdkCallCx`. Same gap on `build_http_request` (Low). [agent 2](security_audit/02_authz_isolation.md#queue-dispatcher-does-not-assert-scriptapp_id--claimedapp_id).
+
+### File storage defense-in-depth (1)
+- **H-G1.** Admin file endpoints (`list_files`, `get_file`, `delete_file`) skip `validate_files_collection`; repo `head`/`get`/`list`/`delete` skip `guard_collection`. Only `create`/`update` validate. Safe today but one bad migration / restore tool can insert a row with `collection = "../../etc"` and the next `get_file` reads arbitrary host files. [agent 6 F-FS-002](security_audit/06_files_pathtraversal.md#f-fs-002--admin-files-api-skips-collection-validation-underlying-headgetlistdelete-skip-the-fs-path-guard-too).
+
+### External integrations (1)
+- **H-H1.** `email::send` from scripts has no rate limit. The `EmailRateLimiter` token bucket exists but is wired only into `users_service` (verification / password-reset flows). A public-HTTP-callable script can burn the operator's SMTP quota or BCC-bomb thousands of recipients per request. [agent 9 F-EXT-H-001](security_audit/09_external_integrations.md#f-ext-h-001--emailsend-from-scripts-is-not-rate-limited-operators-smtp-relay-is-a-free-amplifier).
+
+### CLI / operator tooling (1)
+- **H-J1.** `pic admins create/set --password VALUE` and `pic login --token VALUE` accept secrets on **argv** — they land in shell history, `ps aux`, and `/proc/<pid>/cmdline`. Help text warns; the flag still works. Also, both `pic admins`' `read_password_from_stdin` and `picloud admin reset-password`'s prompt advertise "no echo" but use `read_line`, which echoes. [agent 10 H2 + M2 + L1](security_audit/10_info_disclosure_cli.md#h2--pic-admins-createset---password-value-accepts-the-password-on-argv).
+
+## Mediums and Lows worth surfacing
+
+Full lists live in each agent's file. Highlights:
+
+- **Admin sessions have no absolute (hard-cap) expiry** — only sliding TTL — agent 1.
+- **Password change does not require current-password re-verification** — a hijacked session escalates to permanent ownership — agent 1.
+- **`PICLOUD_COOKIE_SECURE=off` accepted silently** even when `PUBLIC_BASE_URL` is HTTPS — agent 1.
+- **`get_script` / `list_routes_for_script` return 404 before authz** → cross-app id enumeration — agent 2.
+- **`routes:check` / `routes:match` trust a body-supplied `app_id`** — agent 2.
+- **Inactive-principal cron jobs never get the trigger disabled** → re-fires on reactivation under reduced privileges — agent 2.
+- **`MasterKey` + decrypted plaintexts never zeroize on drop** — agent 3.
+- **`auth_middleware::resolve_principal` principal-cache is keyed by token-hash with no eviction on logout/password-change/deactivation** — revocation lag bounded only by TTL — agent 3.
+- **`content_type` accepts CRLF** → response-header injection / handler panic on download — agent 4.
+- **`tracing` text-formatter is vulnerable to log forging via script-controlled queue/topic/collection names** — agent 4.
+- **`serde_json::from_str` in `json::parse` SDK and email-inbound has no recursion / size limits** → stack overflow → process kill — agents 4 and 5.
+- **No `max_modules_per_execution` on Rhai imports**; `invoke()` re-entry inherits caller's permits — agent 5.
+- **No per-app quota on files / KV / docs / queue depth / queue count** — agent 6, agent 8.
+- **No `X-Content-Type-Options: nosniff` / `Referrer-Policy` / `Permissions-Policy` / `Cache-Control: no-store`** anywhere — agent 7.
+- **Outbox has no time-based retention sweep**; stuck-claimed rows accumulate — agent 8.
+- **No SSE subscriber cap per IP / app / process** — agent 8.
+- **No global cap on in-flight HTTP connections / slowloris exposure** — agent 8.
+- **HTTP-async retries have no per-target circuit breaker** — agent 8.
+- **`http_service::validate_url` blocks ports 22/25/465/587 but not 23/110/143/993/995/3306/6379** — narrow exploit window but allow-list would be safer — agent 9.
+- **Distinguishable 404s** ("no app claims host" vs "no route matches") enable app enumeration via Host header — agent 10.
+
+## Cross-cutting recommendations (priority order)
+
+Closing these in roughly this order would land the most defensive value per unit work.
+
+### Tier 1 — close the Criticals (no schema changes; one PR each)
+1. **Drop cookie auth on `/api/v1/admin/*`** (or require synchronizer token). Closes C-1.
+2. **Force download responses to `Content-Disposition: attachment` + `nosniff` + restrictive CSP on file-serving routes**; add a MIME allowlist at upload validation. Closes C-2. Joint owner: agents 6+7.
+3. **Add the security-header layer to Caddy** (CSP for `/admin/*` and `/api/v1/admin/*`, nosniff everywhere, HSTS in prod, `frame-ancestors 'none'`). Closes H-A1, H-A2, H-A3 and turns H-A4 (localStorage token) from acute to defense-in-depth. Agent 7 ships a ready-to-paste snippet.
+
+### Tier 2 — close the highest-leverage Highs
+4. **Login rate limit + global Argon2 semaphore** (H-B1). Cheapest CPU-DoS in the system; pattern already exists in `EmailRateLimiter`.
+5. **Install `engine.on_progress` deadline check** so wall-clock budget actually cancels a runaway Rhai loop (H-C1).
+6. **Bind `aad = "secret:{app_id}:{name}"`** in the AES-GCM seal/open paths for `secrets`, `app_secrets`, and email-trigger inbound secrets (H-D1). Fold into the v1.2 key-versioning pass already on the roadmap.
+7. **Wipe other sessions + revoke all API keys on self-password-change** (H-E1). Mirror `cmd_reset_password`'s behavior.
+8. **Make `inbound_secret` mandatory on email triggers**; add per-`(app_id, trigger_id)` bad-signature token bucket (H-B2).
+9. **Mirror the `script.app_id == row.app_id` cross-check from `build_invoke_request` into queue + HTTP dispatcher arms** (H-F1, plus the Low sibling in `build_http_request`).
+10. **Rate-limit `email::send` from scripts** by moving `EmailRateLimiter` into `EmailServiceImpl` and adding a per-message recipient cap (H-H1).
+
+### Tier 3 — Hardening sweep
+11. **Per-app caps**: trigger/route/cron count (H-B3), cron-scheduler `LIMIT 1000` per tick (H-B4), explicit `DefaultBodyLimit` at router root + Caddy `request_body { max_size }` (H-B5).
+12. **Add per-execution SDK counters** to `SdkCallCx` (kv-ops, files, emails, http, pubsub publishes, invoke depth) — closes H-C2 and bounds invoke amplification.
+13. **`engine.disable_symbol("debug")`** — one-line, closes H-C3.
+14. **Scrub `ExecError::Runtime` for unauthenticated callers** — closes H-C4 plus the principal-leak from join-panic strings.
+15. **Belt-and-suspenders collection validation** in repo `head`/`get`/`list`/`delete` and `validate_files_collection` at admin endpoints — closes H-G1.
+16. **Bootstrap sentinel**: replace `count_active() > 0` gate with a persistent `bootstrap_done` marker — closes H-E2.
+17. **Reject `--password VALUE` / `--token VALUE` argv flags**; require `--password -` (stdin). Fix `read_line` → `rpassword::prompt_password` on every echo-claiming prompt. Closes H-J1.
+
+### Tier 4 — Quotas and observability (paves the way for v1.2)
+18. **Per-app aggregate quotas**: KV row count, files bytes, queue depth, queue count, docs collection size — agents 6 and 8.
+19. **Absolute (hard-cap) session expiry** on `admin_sessions` mirroring `app_user_sessions` — agent 1.
+20. **Audit-log table** for admin actions (`api_key_minted`, `user_promoted`, `app_deleted`, etc.) — agent 10 I4.
+21. **Outbox GC sweep** + circuit-breaker for HTTP-async retries — agent 8 M-1 / M-5.
+22. **`AAD` migration sweep** + `Zeroize` on `MasterKey` and intermediate decrypted plaintexts — agent 3.
+
+## Verified-clean / no-finding observations
+
+These were investigated and judged adequate for the threat model. Recording so future audits don't re-trace:
+
+- **SDK `app_id` discipline**. No Rhai-callable service-trait method accepts `app_id` as a side parameter. Two paths (kv::set, dead_letters::replay) traced end-to-end Rhai→SQL — agent 2.
+- **SQL injection**. 75 dynamic `sqlx::query(...)` callsites; all use positional `$N` binds. Two `format!`-into-SQL patterns interpolate hardcoded `const &str` column lists only. The DSL builder (`docs_repo::build_find_query`) binds every user-supplied path segment and value via `QueryBuilder::push_bind` — agent 4.
+- **Argon2id parameters, RNG selection, constant-time HMAC verification, session-token entropy (256 bits via OsRng), timing-flat username enumeration (dummy-hash path)** — agents 1, 3.
+- **SSRF**. Link-local + private-IP block at parse time; DNS-rebinding defense; redirect re-resolution; cross-origin `Authorization` scrub. End-to-end trace from Rhai `http::get` → `validate_url` → `policy.check` — agent 9.
+- **CLI on-disk credentials are mode-0600 enforced** with re-set on each write; unit test pins it — agent 10.
+- **No `{@html}`, `innerHTML`, `eval`, or `Function()` in the dashboard**; no external CDN `<script>` tags; CodeMirror does not evaluate Rhai as JS — agent 7.
+- **`process::Command` confined to test code**; no shell-out from production paths — agent 4.
+- **Migrations are static SQL** — no `EXECUTE format(...)` blocks; schema-snapshot test pins the final shape — agent 4.
+- **No sandbox escape** (no `unsafe` in executor-core / orchestrator-core; no `eval`/`import` reachable from scripts beyond the per-app module resolver; no file/process/network primitives registered) — agent 5.
+- **Caddy admin** is `admin off` in dev, localhost-default in prod; not network-reachable — agent 9.
+- **`/version`** returns only product/sdk/api/schema/wire versions + `public_base_url`; no build SHA, OS, or internal IP. `/healthz` is literally `"ok"` — agent 10.

+## Notes on remediation methodology
+
+- Most fixes are mechanical and don't require schema changes — Tier 1 + Tier 2 (items 1-10) can each land as a single focused PR with tests.
+- AAD migration (item 6) needs a startup re-encryption sweep; pair it with the v1.2 key-versioning pass already on the roadmap (memory: [Release state snapshot 2026-06-07](#)).
+- Per-app quotas (item 18) need an `app_quotas` schema migration; defer to v1.2.
+- The audit deliberately did not exercise cluster mode (skeleton crates). The crypto AAD migration and inbound nonce dedup both regress under cluster mode if shipped as-is — call out in the v1.3 readiness checklist.
+- Severity calibration assumes solo-dev / Pi-class hardware. A single anonymous request fully saturating one execution worker for 5 minutes is treated as High, not Low.

 //!
 //! Replaces `DummyModuleResolver` in `Engine::build_engine`. Constructed
-//! fresh per `Engine::execute` call: holds an `Arc<SdkCallCx>` so every

-//! — that's the load-bearing cross-app isolation property.
+//! fresh per `Engine::execute` call.
+//!
+//! **Lexical resolution (§5.5).** An `import "<name>"` resolves against the
+//! module set visible at the **importing script's own defining node**,
+//! walking up its group chain — not the inheriting app's effective view.
+//! The importing node is read from Rhai's `_source` (the importing AST's
+//! source tag, which the resolver sets to each module's owner) and falls
+//! back to `default_origin` (the entry script's defining node) for the
+//! top-level AST. So an inherited group script's imports seal to the group
+//! (a leaf can't shadow them — the trust boundary), while every SDK call
+//! *inside* a module still scopes to the inheriting app via `cx.app_id`.
+//!
+//! **Extension points (§5.5).** A node may opt a module name OUT of sealing
+//! by declaring it an extension point: an importer on that node's chain then
+//! resolves the name against the *inheriting app's* effective view
+//! (`App(cx.app_id)`), with the declared default body as fallback — so each
+//! descendant app supplies its own impl. The "is this an extension point"
+//! check keys on the importer's `origin` (trusted), so only the declaring
+//! parent can open the inversion; a descendant can't hijack a sealed import.
 //!
 //! Three runtime invariants are enforced:
 //!
-//! 1. **Cross-app isolation** — `ModuleSource::lookup` is called with
-//!    `&cx`; the Postgres impl scopes by `cx.app_id` (never by a
-//!    script-passed argument).
+//! 1. **Lexical isolation** — `ModuleSource::resolve` is keyed by the
+//!    importing node's owner (a trusted dispatch-derived value), never a
+//!    script-passed argument.
 //! 2. **Cycle detection** — an in-progress-imports stack rejects
 //!    `A → B → A` with `ErrorInModule(... circular import detected ...)`.
 //! 3. **Depth limit** — guards against deep but acyclic chains
 //!    (default 8, override via `PICLOUD_MODULE_IMPORT_DEPTH_MAX`).
 //!
-//! Compiled modules are cached per `(app_id, name)` and invalidated by

+//! `invoke()` Rhai bridge — synchronous, same-app, re-entrant.
+//!
+//! ```rhai
+//! let result = invoke("/api/payments/process", #{ order_id: 123 });
+//! let result = invoke(script_id("uuid-..."), args);
+//! ```
+//!
+//! Re-entrancy: the bridge captures `Arc<Engine>` (via
+//! `Engine::self_arc`) and calls `engine.execute(&source, req)` directly
+//! inside the caller's `spawn_blocking` thread. Same engine instance,
+//! same `Services`, same `Limits` — only the per-call `SdkCallCx`
+//! changes (the callee gets `trigger_depth + 1` and a fresh
+//! `execution_id`).
+//!
+//! Cross-app rejection happens at the `InvokeService::resolve` layer —
+//! every method derives `app_id` from `cx.app_id` and returns
+//! `InvokeError::CrossApp` if the resolved script belongs elsewhere.
+//!
+//! Depth bound: `cx.trigger_depth + 1 > limits.trigger_depth_max` →
+//! `InvokeError::DepthExceeded`. Shared with the trigger fan-out depth
+//! limit per the design notes (no separate `invoke_depth_max`).
+//!
+//! Closures captured across the `invoke` boundary are rejected at the
+//! args-to-JSON conversion — `FnPtr` doesn't survive serialization and
+//! re-entry into a fresh engine instance is the wrong scope for it
+//! anyway.
+//!
+//! `invoke_async()` writes an outbox row (see `InvokeService::enqueue_async`)
+//! and returns immediately with the new `ExecutionId` as a string. The
+//! dispatcher fires it through the standard executor path; commit 10
+//! wires the dispatcher's `OutboxSourceKind::Invoke` arm.

+//! before any registration would matter) — so we ship `retry::run(...)`
+//! instead. Documented in HANDBACK §7.
+//!
+//! `retry::run(policy, closure)` calls the closure; on throw it sleeps
+//! per the policy and re-invokes. Sleeps run via `tokio::time::sleep`
+//! through `TokioHandle::block_on` — the bridge is already inside the
+//! caller's `spawn_blocking` thread, so blocking is fine.

+//! Closures share the caller's engine + cx (Rhai's `FnPtr` is invoked
+//! via `call_within_context` on the same engine). If the closure calls
+//! `invoke()`, the inner call gets a fresh cx with `trigger_depth + 1`
+//! via the invoke bridge — retry doesn't see or interfere with that.

+//! CRUD over the `app_user_sessions` table (v1.1.8 data-plane sessions).
+//!
+//! Mirrors the shape of `admin_session_repo` (token hash as PK, sliding
+//! window, prune on expiry) with three additions:
+//!
+//!   * `app_id` is part of every row so cross-app isolation is bright
+//!     at the SQL layer. Lookups by token hash still join on app_id —
+//!     a token issued for app A cannot be used to authorize a request
+//!     into app B even if the hash collides (which it won't, but the
+//!     defense-in-depth is cheap).
+//!   * `absolute_expires_at` is the hard cap. The repo writes whatever
+//!     `new_expires_at` it's handed on touch; the service computes the
+//!     min of (now + ttl, absolute_expires_at) so a session that's
+//!     been bumped a hundred times still dies at the absolute cap.
+//!   * `revoked_at` is explicit revocation. Lookups reject revoked
+//!     rows immediately so a "revoke all sessions" admin action takes
+//!     effect before the next GC sweep runs.
+//!
+//! The token never appears in this module — only the SHA-256 hash.
