fix(project-tool): close M5+M3 review findings (authz + data-loss + None-path)

A fresh two-lens end-to-end review (security + correctness) of the committed
M5/M3 diff surfaced four real defects; all fixed here with regressions.

- HIGH (M5 authz bypass) — `enforce_env_approval` resolved a group node with a
  bare `get_by_slug` and SKIPPED the GroupAdmin gate on miss. A node addressed
  by the group's UUID (which the apply still resolves) let a group EDITOR apply
  to a confirm-required env without admin. Now resolves UUID-or-slug and fails
  closed, mirroring authz_tree / prepare_tree. Raw-wire regression added.

- FIX-FIRST (M3 correctness) — the legacy `project_key=None` path was not inert:
  the conflict loop pushed a conflict for any owned group (`Some(oid) != None`),
  so a keyless/direct-API tree apply touching an already-claimed group was
  spuriously 409'd. Ownership classification is now gated on a key being present
  (the discriminator is key-present, not project-persisted, so a first-ever
  keyed apply still sees an already-owned group as a conflict). Regression added.

- FIX-FIRST (M3 data-loss) — the structural-prune guard checked collection
  MARKERS (`group_collections`) but data outlives its marker: un-declaring a
  `collections=[...]` entry drops the marker while the kv/docs/files/queue rows
  survive until group delete. A dropped-then-pruned group would silently CASCADE
  that orphaned data. The guard now EXISTS-checks the actual data tables
  (group_kv_entries/docs/files/queue_messages) plus secrets + markers.

- MEDIUM (audit) — group ownership takeover (and claim) now emit a
  tracing::info! audit line with the actor + ousted owner, matching the M5
  gated-env audit. Previously only a report counter.

Also: documented WHY `pic plan --dir` mints the project key (a rare write for a
read-only command) — plan and apply must present the same key or the ownership
token folds diverge and trip a spurious StateMoved.

Re-verified: 411 manager-core lib tests; 28 CLI journeys (incl. 2 new
regressions: uuid-slug admin gate, keyless legacy apply); workspace clippy
-D warnings + fmt clean.

+# 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.

+### 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
+- **Severity:** Medium
+- **Location:** [dashboard/src/routes/apps/[slug]/dead-letters/+page.svelte:175-309](dashboard/src/routes/apps/[slug]/dead-letters/+page.svelte#L175-L309), [dashboard/src/routes/apps/[slug]/files/+page.svelte:174-228](dashboard/src/routes/apps/[slug]/files/+page.svelte#L174-L228), [dashboard/src/routes/apps/[slug]/users/+page.svelte:364-466](dashboard/src/routes/apps/[slug]/users/+page.svelte#L364-L466), [dashboard/src/routes/apps/[slug]/users/invitations/+page.svelte:254-325](dashboard/src/routes/apps/[slug]/users/invitations/+page.svelte#L254-L325), [dashboard/src/routes/apps/[slug]/queues/+page.svelte:93-128](dashboard/src/routes/apps/[slug]/queues/+page.svelte#L93-L128)
+- **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-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-022** — `$effect` blocks reference variables via `void slug;` to force tracking — Svelte 5 cargo-cult; the synchronous deref inside `load()` already registers the dependency. [dead-letters/+page.svelte:32-37](dashboard/src/routes/apps/[slug]/dead-letters/+page.svelte#L32-L37)

+- **F-S-036** — Dispatcher uses true `rand::thread_rng()`; `retry::run` uses `DefaultHasher`-based pseudo-randomness that gives identical jitter for same `(span, raw)` pairs — defeats jitter purpose under concurrent retries.

+- **F-M-014** — `pgcrypto` extension declared once in 0001; subsequent migrations rely on `gen_random_uuid()` without re-declaring. Belt-and-suspenders `CREATE EXTENSION IF NOT EXISTS pgcrypto` in each migration that uses it.
+- **F-T-011** — `subscribeTopic` sends `Last-Event-ID` header even though server-side replay isn't implemented (README is honest). Test suite doesn't assert the header is actually sent. [subscribe.ts:51-52](clients/typescript/src/subscribe.ts#L51-L52)

+## 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
+  drift).
+- **F3 — fmt + clippy attestation as literal output**: see HANDBACK §8.
+- **F4 — `TIMING_FLAT_DUMMY_HASH` dedup**: inline copy in
+  `crates/manager-core/src/auth_api.rs::login` now references the
+  shared `crate::auth::TIMING_FLAT_DUMMY_HASH` const. `grep -rn` for
+  the PHC literal returns exactly one hit.
+- **F5 — clippy without cold cache**: incremental cache used; HANDBACK
+  §8 notes the explicit choice.
+
+### Notes
+
+- New env vars:
+  - `PICLOUD_QUEUE_RECLAIM_INTERVAL_MS` (default 30000) — visibility-
+    timeout reclaim cadence.
+  - `PICLOUD_QUEUE_DEFAULT_VISIBILITY_TIMEOUT_SECS` (default 30) —
+    visibility timeout fallback when the trigger create request omits
+    one. Per-trigger column overrides this.
+- SDK schema bumped to 1.10.
+- `@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.
+
+## v1.1.7 — Configuration & Email (unreleased)
+
+The operational-config layer: **encrypted per-app secrets**, **outbound
+email**, and an **inbound email trigger** — plus the long-missing
+**dead-letter handler wiring** and **at-rest encryption of the realtime
+signing key**. All at-rest encryption uses a single process master key
+(AES-256-GCM); key rotation is deferred to v1.2.
+
+### Added — Encryption infrastructure
+
+- **Process master key** from `PICLOUD_SECRET_KEY` (base64 of exactly 32
+  bytes). REQUIRED at startup — an unset or malformed key is fatal.
+  Generate one with `openssl rand -base64 32`. A deterministic in-memory
+  dev key is used ONLY when `PICLOUD_SECRET_KEY` is unset AND
+  `PICLOUD_DEV_MODE=true` (with a prominent startup warning); there is no
+  quiet unencrypted mode.
+- **`picloud_shared::crypto`** — `encrypt`/`decrypt` envelope:
+  `Aes256Gcm`, 96-bit CSPRNG nonce, 128-bit auth tag appended to the
+  ciphertext (RustCrypto `Aead` layout). Both ciphertext and nonce are
+  stored.
+- **Key rotation is out of scope.** Changing `PICLOUD_SECRET_KEY` between
+  deploys renders all existing ciphertext undecryptable. v1.2+ adds
+  key-version columns + a re-encryption pass.
+
+### Added — Encrypted per-app secrets
+
+- **`secrets::{get,set,delete,list}(name)`** SDK — collection-less,
+  per-app. `set` accepts a String/Map/Array (JSON-encoded then encrypted);
+  `get` returns the same Rhai type back; missing → `()`. 64 KB plaintext
+  cap (`PICLOUD_SECRET_MAX_VALUE_BYTES`). `migrations/0023_secrets.sql`.
+- **Admin API** `GET/POST/DELETE /api/v1/admin/apps/{id}/secrets` — list
+  returns names + `updated_at` only, **never values**.
+- **Dashboard Secrets tab** — list names + last-modified, create/update
+  (masked value with a confirm-gated reveal), delete with confirm.
+- `Capability::AppSecretsRead`/`Write` (→ `script:read` / `script:write`).
+  No new Scope variants (seven-scope commitment). Secret writes
+  deliberately do **not** emit trigger events.
+
+### Added — Outbound email
+
+- **`email::send` / `email::send_html`** SDK over an SMTP relay
+  (`lettre`). Config from `PICLOUD_SMTP_HOST/PORT/USER/PASSWORD/TLS/
+  TIMEOUT_SECS`; if HOST/USER/PASSWORD aren't all set the service runs in
+  **disabled mode** (every send throws `NotConfigured`, warned at
+  startup). Required `to`/`from`/`subject` + one of `text`/`html`;
+  RFC 5322-ish address validation; 25 MB per-message cap
+  (`PICLOUD_EMAIL_MAX_MESSAGE_BYTES`); `reply_to` defaults to `from`.
+  Per-call connection (pooling deferred to v1.2); per-app `from`
+  validation / SPF / DKIM are the operator's SMTP-relay concern.
+- `Capability::AppEmailSend` (→ `script:write`).
+
+### Added — Inbound email (`email:receive` trigger)
+
+- **Webhook receiver** `POST /api/v1/email-inbound/{app_id}/{trigger_id}`
+  — a provider (Mailgun / Postmark / SendGrid / SES) POSTs the generic
+  JSON shape `{from,to[],cc[],subject,text,html,message_id}`; the
+  receiver verifies the optional HMAC signature, normalizes to
+  `TriggerEvent::Email`, and enqueues an outbox row. 202 accepted, 401
+  bad/missing signature, 404 missing/wrong-kind/cross-app, 422 malformed.
+  Handlers see `ctx.event.email`. `migrations/0024_email_triggers.sql`.
+- **Admin** `POST /api/v1/admin/apps/{id}/triggers/email` +
+  dashboard form (with the webhook URL + expected payload). The HMAC
+  `inbound_secret` is stored **encrypted** via the master key (deviation
+  from the original plaintext design — see HANDBACK §7).
+- Provider-specific payload unmarshallers + inbound attachments → v1.2.
+  Native SMTP listener → v1.3+.
+
+### Security/correctness fix (retroactive) — dead_letter handlers
+
+The `dead_letter` trigger kind has been registerable since v1.1.1 but,
+due to missing dispatcher wiring (`list_matching_dead_letter` had no
+production caller), handlers have **never fired**. Any deploy running
+v1.1.1 through v1.1.6 with `dead_letter` triggers configured has had
+silently non-functional handlers. v1.1.7 fixes the wiring; existing
+`dead_letters` rows remain (no migration needed) but only NEW
+dead-letter events (post-v1.1.7) trigger handlers. To process older
+rows, use the existing admin replay surface to re-enqueue them.
+
+### Changed — Realtime signing key encrypted at rest (two-phase)
+
+`app_secrets.realtime_signing_key` was stored as 32 plaintext bytes. It
+is now encrypted with the master key. `migrations/0025_encrypt_realtime_keys.sql`
+adds NULL-able encrypted columns and drops `NOT NULL` on the plaintext
+column; a startup task encrypts pre-existing rows; the read path prefers
+the encrypted columns and falls back to plaintext during the compat
+window. **v1.1.8 will drop the plaintext `realtime_signing_key`
+column** — operators should upgrade through v1.1.7 (which performs the
+encryption) before v1.1.8.
+
+### Notes
+
+- **New deps:** `aes-gcm` (RustCrypto AEAD), `lettre` (SMTP).
+- **New env vars:** `PICLOUD_SECRET_KEY` (required), `PICLOUD_DEV_MODE`,
+  `PICLOUD_SECRET_MAX_VALUE_BYTES`, `PICLOUD_SMTP_HOST/PORT/USER/PASSWORD/
+  TLS/TIMEOUT_SECS`, `PICLOUD_EMAIL_MAX_MESSAGE_BYTES`.
+- **SDK schema** 1.7 → 1.8; **dashboard** 0.12.0 → 0.13.0.

+# 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.

+## App as built
+
+| Surface | Implementation |
+|---|---|
+| `POST /auth/register` | `register.rhai` → `users::create` |
+| `POST /auth/login` | `login.rhai` → `users::login` → session token |
+| `GET /todos` | `todos_list.rhai` → `docs.find({user_id})` |
+| `POST /todos` | `todos_create.rhai` → `docs.create` + `pubsub::publish_durable("activity", …)` |
+| `PATCH /todos/:id` | `todos_update.rhai` → ownership check + complete + publish |
+| `DELETE /todos/:id` | `todos_delete.rhai` → ownership check + delete |
+| cron `0 0 3 * * *` | `cleanup.rhai` → purge completed todos older than 7d |
+| realtime | SSE `GET /realtime/topics/activity` |
+
+7 scripts, 6 routes, 1 cron trigger, 1 app, 1 domain claim, 1 pubsub topic. Sources in
+`/tmp/todo-app/*.rhai`.
+
+---
+
+## 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.
+
+## Reproduction
+
+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)
+
+```
+pic login --username admin --password-stdin           # F3

+
+## Data-plane journey (all green)
+
+```
+register carol/dave                       201 / 201
+duplicate carol (email_available, S1)     409  {"error":"email already registered"}

+POST /todos  (method-branch create, F4)   201 ×2
+GET  /todos  (same script, list, F4)      200  count:2
+PATCH /todos/:id complete                 200
+dave PATCH/DELETE carol's todo            403 / 403  (ownership)
+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.**

-   - `auth_mode='public'` → allow;
-   - `auth_mode='token'` → verify HMAC (present, signed by this app's key,

-### Publish wiring (order + failure modes) — §8 ordering chosen

-`tokio::spawn` whose `JoinHandle` is awaited, so a panicking broadcaster
-becomes a `warn` log, never a failed publish (the durable deliveries
-already committed). One `published_at` instant is shared by both paths.
-**Brief-internal contradiction flagged** — see §9.
 
-## 3. Client lib implementation notes
+**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.
 
-- **Build:** **tsup** (dual ESM+CJS + `.d.ts`), tests **vitest**, lint =
+**Dead-letter** (handler threw, `attempt >= max_attempts`): single
-  `tsc --noEmit` (strict; `noUncheckedIndexedAccess`, no `any` in exports).
+transaction — `INSERT INTO dead_letters` with `source = "queue"`,
-- **Layout:** `src/{index,client,endpoint,subscribe,auth,types}.ts` +
+`op = "receive"`, the original payload wrapped in a shape mirroring
-  `src/react/index.ts` + `src/svelte/index.ts`; subpath exports
+`TriggerEvent::Queue` (so the existing `fan_out_dead_letter` path on
-  `@picloud/client/react` and `@picloud/client/svelte` via package `exports`.
+the outbox arm can fire registered `dead_letter` triggers off the new

+row without any special-casing), then `DELETE FROM queue_messages`.
-  `EventSource`) so the lib can (a) detect a **401** on (re)connect and call
-  `onTokenExpired` to refresh, (b) send **`Last-Event-ID`** on resume
-  (server ignores it in v1.1.6 — client ships ready), and (c) apply its own
-  **exponential backoff** (base 1s → ×2 → cap 30s; reset on successful
-  open). Token rides in `?token=` (EventSource-parity). React Native caveat
-  documented in the README (supply a streaming-`fetch` polyfill).
-- **zod/valibot adapter:** the `Validator<T> = { parse(input): T }` shape.
-  A Zod schema satisfies it directly; Valibot wraps in one line. Used by
-  `endpoint(...).get({ validate })` and `subscribe(..., { validate })`. No
-  hard dep.
 
-## 4. v1.1.5 follow-ups
+**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).
 
-- **Dispatcher e2e (six):** `dispatcher_delivers_{kv,docs,cron,files,pubsub,
+## 3. `invoke()` re-entrancy notes
-  dead_letter}_to_handler` in `crates/picloud/tests/dispatcher_e2e.rs`.
-  Verified green against a real Postgres (all 6).
-- **Empty-blob — RELAXED** (per the asked decision). Dropped the
-  `data.is_empty()` rejection in `NewFile::validate` **and** `FileUpdate::
-  validate` (the latter for consistency — flagged in §7). Flipped the
-  pinning test in `files_service.rs` and added `empty_file_round_trips`.
-- **Orphan sweep:** `spawn_files_orphan_sweep` (`files_sweep.rs`), every 6h
-  (`PICLOUD_FILES_ORPHAN_SWEEP_INTERVAL_SEC`), unlinks `*.tmp.*` older than
-  1h (`PICLOUD_FILES_ORPHAN_TMP_TTL_SEC`); logs dirs-walked / files-deleted /
-  bytes-reclaimed. No DB cross-check (v1.3+). Tested: deletes old tmp, keeps
-  young tmp, keeps non-tmp, missing-root no panic.
 
-## 5. Schema decisions beyond the brief
+**Engine sharing** via `Engine::self_weak: OnceLock<Weak<Engine>>`.
-None — `0021_topics.sql` and `0022_app_secrets.sql` match the brief's DDL
+The picloud binary:
-verbatim. Schema-snapshot golden re-blessed on a fresh DB (only the two new
-tables added; PK/FK `ON DELETE CASCADE` + the `auth_mode` CHECK present).
 
-## 6. How to verify locally
+```rust
-See §8 below.
+let engine = Arc::new(Engine::new(engine_limits, services));
+engine.set_self_weak(Arc::downgrade(&engine));
+```
 
-## 7. Decisions beyond the brief — every prompt-default deviation
+`Engine::execute_ast` reads `self.self_arc()` (which upgrades the
-1. **Dispatcher e2e location:** the brief says
+`Weak`) and threads `Option<Arc<Engine>>` through
-   `crates/manager-core/tests/dispatcher_e2e.rs`; I put it in
+`sdk::register_all(...)` to the invoke bridge.
-   **`crates/picloud/tests/`**. `build_app` (the full dispatcher + scheduler
-   + executor wiring) lives in the `picloud` crate; a manager-core test would
-   need a manager→picloud dev-dependency cycle or a hand-rolled re-wire of
-   build_app. The picloud harness (`server_with_app` pattern) is proven and
-   the tests run green against a real DB. Gating uses the **schema_snapshot
-   pattern** (env check + early return), NOT `#[ignore]`, so CI's plain
-   `cargo test` with `DATABASE_URL` runs them while local stays green — as
-   the brief requested.
-2. **Empty-blob relaxation extended to `FileUpdate::validate`** — the brief
-   names only `NewFile::validate`. Relaxing create-empty but rejecting
-   update-to-empty would be an inconsistent API, so I relaxed both.
-3. **Publish order: §8 (broadcast AFTER outbox commit)**, not §4 (broadcast
-   FIRST). The two sections contradict; §8 is the dedicated, numbered,
-   rationale-backed section. See §9.
-4. **Topic-name validation** — `topics_api` rejects empty names and names
-   containing `*` (external pattern subscription is v2). The brief didn't
-   specify name validation; this is a small guard.
-5. **Client lib lint = `tsc --noEmit`** (not eslint) to keep devDeps lean;
-   strict typecheck is the gate. "No `any` in exports" is enforced by review
-   + strict TS, not an eslint rule.
-6. **Cron e2e poll budget = 45s** — the cron scheduler skips its first tick
-   then ticks every 30s (default). The test polls 45s so it passes at the
-   default; set `PICLOUD_CRON_TICK_INTERVAL_MS=1000` to make it ~2s in CI.
 
-## 8. Attestation (gate runs on this HEAD)
+**`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).
+
+**Re-entry path** (inside `invoke.rs::invoke_blocking`):
+
+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
+
+**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.
+
+**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`.
+
+**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").
+
+**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.
+
+**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.
+
+**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).

 ## 9. Open questions for the reviewer
-1. **§4 vs §8 ordering contradiction (load-bearing, flagged not
+
-   reinterpreted):** §4 says "realtime broadcast FIRST, then transactional
+1. **`retry::run` rename** (D1): is `run` an acceptable script-side
-   outbox fan-out"; §8 says broadcast AFTER the fan-out commits (numbered
+   name? Alternatives that compile: `retry::do_attempts`,
-   steps 1–4). I implemented **§8** (dedicated section + failure-mode
+   `retry::attempt`. `run` reads cleanest in practice but is
-   rationale). If §4's ordering was intended, the broadcast should move
+   slightly less specific than `with`.
-   before `fan_out_publish` — but then a publish whose outbox write fails
+2. **`invoke()` path-resolution method**: defaulted to POST→GET
-   would still have notified SSE subscribers of an event that never durably
+   fallback. A future surface bump could let scripts pass a method
-   happened, which seems wrong. Please confirm §8 is correct.
+   (`invoke("/api/foo", "GET", #{})`) — flagged as v1.2 follow-up.
-2. **Dead-letter → handler fan-out appears unwired (see §10).** Confirm
+3. **`ctx.trigger_depth` not in `ctx`**: noted as a v1.2 follow-up
-   whether the `dead_letter` trigger source is intended to fire in v1.1.x.
+   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
-**`dead_letter` trigger handlers do not fire on dead-letter creation.**
-`dispatcher::handle_failure` writes the `dead_letters` row via
-`DeadLetterRepo::insert` but never enqueues outbox deliveries for matching
-`dead_letter`-kind triggers. `TriggerRepo::list_matching_dead_letter` is
-defined + implemented but has **no production caller** (only the trait def,
-the Postgres impl, and a test fake). So a registered `dead_letter` trigger
-never runs from an exhausted-retry event. This predates v1.1.6 (the design
-notes §4 describe it shipping in v1.1.1). I did **not** fix it (out of
-v1.1.6 scope) — flagging for the reviewer. Consequence: the
-`dispatcher_delivers_dead_letter_to_handler` e2e test asserts the
-**dead-letter row is produced** (the wired behavior) rather than a handler
-firing; documented in the test, and is the honest assertion until the
-fan-out lands.
 
-No new security gaps introduced. Cross-app isolation holds: `subscriber_token`
+**L1 — Pre-existing clippy lints surfaced during the F3 attestation.**
-claims carry `app_id` and are signed per-app; the SSE authority rejects
+Six lints — two on new v1.1.9 code (`sdk/invoke.rs::_LIMITS_IS_COPY`
-cross-app tokens (a per-app key already fails the signature, plus an explicit
+items-after-test-module, `picloud/lib.rs::engine_limits`
-`claims.app_id == app_id` check); topic admin endpoints bind the capability
+field-reassign-with-default), four others on new v1.1.9 SDK paths
-to the path `app_id` after loading the app; the broadcaster keys channels by
+(`retry.rs`, `queue.rs`, `dispatcher.rs`). All fixed alongside the
-`(AppId, topic)` so app A's publishes never reach app B's subscribers
+new code in commit `chore(v1.1.9): clippy clean — workspace -D warnings`
-(unit-tested).
+so the gate is green now. No carry-forward latent findings from main.
 
-## 11. Deferred items (beyond this prompt's OUT list)
+**L2 — Dashboard pre-existing Playwright errors (149)** in
-None added. Everything on the brief's OUT list stayed out (WebSocket,
+`tests/e2e/**/*.spec.ts` — `Cannot find module '@playwright/test'`.

-## 12. Known limitations / rough edges
+## 11. Deferred items
-- SSE delivery is best-effort at-most-once; a slow consumer past the
+
-  broadcast buffer loses events with no server-side replay (by design).
+**Not deferred:** `retry::*` shipped as `retry::run` (with the rename
-- The client lib's streaming-`fetch` SSE needs a polyfill on runtimes
+deviation flagged in §7). The full v1.1.9 scope landed.
-  without `fetch` body streaming (React Native) — documented.
+
-- Cron e2e takes ~31s at the default 30s tick interval (45s poll budget);
+**Standing v1.2+ deferred list** (no change from the brief):
-  set `PICLOUD_CRON_TICK_INTERVAL_MS=1000` to speed it up.

+- Queue priorities
-  rotation API must clear it.
+- 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
+
+- **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.

 ## Verdict
 
-**APPROVE — ready to merge to `main` as v1.1.6.**
+**APPROVE — ready to merge to `main` as v1.1.9.**
 
-The largest release in v1.1.x lands cleanly: realtime channels (topics table + admin endpoints + SSE handler + in-process broadcaster + HMAC subscriber tokens + `app_secrets` table + `pubsub::subscriber_token` SDK) + the first frontend package (`@picloud/client@1.0.0`: typed HTTP + streaming-fetch SSE + auth helpers + React/Svelte hooks) + all three v1.1.5 follow-ups (six dispatcher e2e tests, empty-blob relaxed, orphan tmp-sweeper).
+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.
 
-Two open questions raised in HANDBACK §9/§10 — I'll weigh in:
+**§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. **§4-vs-§8 ordering contradiction in the brief**: the agent picked §8 (broadcast AFTER outbox commit) and flagged the contradiction transparently rather than silently reinterpreting. **§8 is the correct call** — see §3 below. This is the v1.1.4 retro lesson on brief-internal contradictions working as intended.
+**Reviewer-independent verification reproduced everything material:**
-2. **Latent finding: `dead_letter` trigger handlers never fire** — pre-existing bug from v1.1.1 confirmed. Not v1.1.6's responsibility to fix; correctly out-of-scope. See §4 below for the verification and the v1.1.7 follow-up.
 
-Three documented deviations from prompt defaults (all in HANDBACK §7), all defensible. One test-count discrepancy worth noting (582 vs 482 claim — see §5). None of this blocks merge.
+- 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
+
+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.

 ## 2. Design conformance (spot-checks)
 
 | Decision / requirement | Where it lives | Verdict |
 |---|---|---|
-| `topics` table (explicit registration for externally-subscribable topics) | [0021_topics.sql](crates/manager-core/migrations/0021_topics.sql) | ✅ Matches brief verbatim; `auth_mode` CHECK allows `('public', 'token')` |
+| Queue table IS the outbox for queue semantics (no double-buffering) | [queue_repo.rs::claim](crates/manager-core/src/queue_repo.rs#L177-L212) + [dispatcher.rs::tick_queue_arm](crates/manager-core/src/dispatcher.rs#L152-L164) | ✅ No `OutboxSourceKind::Queue`; the dispatcher's `tick_queue_arm` enumerates consumers and runs one atomic claim per `(app_id, queue_name)` per tick |
-| Topic admin endpoints with `AppTopicManage` gating | manager-core/src/topics_api.rs | ✅ Bit-flip is its own PATCH endpoint as required |
+| Single round-trip atomic claim via `UPDATE ... WHERE id = (SELECT ... FOR UPDATE SKIP LOCKED LIMIT 1) RETURNING` | [queue_repo.rs:184-201](crates/manager-core/src/queue_repo.rs#L184-L201) | ✅ Verbatim per the brief; increments `attempt`, sets `claim_token` + `claimed_at` |
-| **SSE handler — topic missing OR `external_subscribable=false` BOTH collapse to 404** | orchestrator-core/src/realtime_api.rs | ✅ Prevents internal-topic probing |
+| Auto-ack: `DELETE WHERE id = $1 AND claim_token = $2` (lease guarantee) | [queue_repo.rs:218-224](crates/manager-core/src/queue_repo.rs#L218-L224) | ✅ Stale dispatcher whose lease expired can't delete a re-claimed message |
-| **HMAC token: 401 is generic** (doesn't leak which check failed) | RealtimeAuthority impl | ✅ |
+| Auto-nack: clear claim + set `deliver_after = NOW() + retry_delay` | [queue_repo.rs:232-245](crates/manager-core/src/queue_repo.rs#L232-L245) | ✅ Same lease-token filter; idempotent |
-| Token via `Authorization: Bearer` OR `?token=` (EventSource compat) | realtime_api.rs | ✅ Required because browsers can't set headers on EventSource |
+| Visibility-timeout reclaim every `PICLOUD_QUEUE_RECLAIM_INTERVAL_MS` (default 30s) | [dispatcher.rs::spawn lines 87-104](crates/manager-core/src/dispatcher.rs#L87-L104) + [queue_repo.rs::reclaim_visibility_timeouts](crates/manager-core/src/queue_repo.rs#L247-L262) | ✅ Separate tokio task; UPDATE JOIN triggers + queue_trigger_details; verified by `queue_e2e::queue_visibility_timeout_reclaim` |
-| Heartbeat every 30s (env-overridable) | realtime_api.rs | ✅ `PICLOUD_REALTIME_HEARTBEAT_SEC` knob |
+| Dead-letter integration through existing `dead_letters` table + `fan_out_dead_letter` path | [dispatcher.rs::handle_queue_failure](crates/manager-core/src/dispatcher.rs#L292-L338) | ✅ Source `"queue"`, op `"receive"`; existing `fan_out_dead_letter` on the outbox arm reads the new row without special-casing |
-| `RealtimeBroadcaster` trait in shared; in-process impl in orchestrator-core | shared/src/realtime.rs + orchestrator-core/src/realtime.rs | ✅ Cluster-mode swap point preserved |
+| Exactly one consumer per queue enforced | [trigger_repo.rs::create_queue_trigger](crates/manager-core/src/trigger_repo.rs) via `pg_advisory_xact_lock` | ✅ Per D5 — partial unique cross-table index is infeasible; advisory-lock + SELECT-then-INSERT in one transaction is the right workaround |
-| Channel capacity env-overridable (default 64); slow consumers drop oldest | orchestrator-core/src/realtime.rs | ✅ `PICLOUD_REALTIME_BROADCAST_CAPACITY` |
+| Trigger-execution principal = principal that registered the trigger | dispatcher.rs::dispatch_one_queue lines 231-235 (resolves via `principals.resolve(consumer.registered_by_principal)`) | ✅ Consistent with v1.1.1 design-notes §4 |
-| GC task drops `receiver_count == 0` senders | orchestrator-core/src/realtime.rs `spawn_realtime_gc` | ✅ |
+| Cross-app `invoke()` rejection at three layers | [invoke_service.rs::resolve_id](crates/manager-core/src/invoke_service.rs#L43-L64) (service); `get_by_name`/RouteTable snapshot (repo/routes); dispatcher `build_invoke_request` (defense-in-depth) | ✅ Verified by `invoke_e2e::invoke_cross_app_rejects` (returns `InvokeError::CrossApp`) |
-| **HMAC signing key persisted to `app_secrets` table** (not derived from instance secret) | [0022_app_secrets.sql](crates/manager-core/migrations/0022_app_secrets.sql) + app_secrets_repo.rs | ✅ Took the recommended path; 32 random bytes, `ON CONFLICT DO NOTHING` for concurrency |
+| Same-app `invoke()` re-entrancy via shared engine + fresh `SdkCallCx` (trigger_depth + 1) | [engine.rs:91-101 + 197](crates/executor-core/src/engine.rs#L91-L197) + sdk/invoke.rs::invoke_blocking | ✅ `Engine::self_weak: OnceLock<Weak<Engine>>` + `set_self_weak` + `self_arc()`; cycle stays broken; bridge gets `None` only on engine drop |
-| In-memory key cache mitigates per-token DB lookup | RealtimeAuthorityImpl | ✅ Correct because keys never rotate in v1.1.6 — flagged in HANDBACK §12 as needing invalidation when rotation lands |
+| `Limits::trigger_depth_max` synced from `TriggerConfig::max_trigger_depth` (D4) | sandbox.rs Limits + picloud/src/lib.rs build_app | ✅ `PICLOUD_MAX_TRIGGER_DEPTH` governs both dispatcher fan-out and invoke depth |
-| `pubsub::subscriber_token(topics, ttl)` SDK | [pubsub_service.rs:203+ mint_subscriber_token](crates/manager-core/src/pubsub_service.rs#L203) | ✅ Anonymous cx throws; unregistered topic throws; ttl clamped 10s–24h |
+| `invoke_async` runs once (no retry) | invoke_service.rs::enqueue_async + dispatcher.rs::build_invoke_request synthesizes `retry_max_attempts = 1` | ✅ Per D7 — callers wrap in `retry::run` if they want retries |
-| Token TTL knobs env-overridable | pubsub_service.rs | ✅ `PICLOUD_SUBSCRIBER_TOKEN_TTL_{MIN,MAX,DEFAULT}_SEC` |
+| `retry::policy` clamps: max_attempts ∈ [1,20], base_ms ∈ [1, 60_000], jitter_pct ∈ [0,100] | [retry.rs::build_policy](crates/executor-core/src/sdk/retry.rs#L135-L187) | ✅ Saturating clamps with clear errors on bogus backoff strings |
-| **Publish wiring: outbox commit FIRST, then broadcast on child task** | [pubsub_service.rs:138-201](crates/manager-core/src/pubsub_service.rs#L138-L201) | ✅ §8 ordering, broadcast inside `tokio::spawn` whose `JoinHandle` is awaited so panics surface as warn logs |
+| `retry::run(policy, fn_ptr)` re-invokes FnPtr through NativeCallContext | [retry.rs::retry_run](crates/executor-core/src/sdk/retry.rs#L189-L200+) | ✅ Closure shares caller's engine + cx; inner `invoke()` calls get fresh cx via the invoke bridge — retry doesn't interfere |
-| `published_at` stamped once, shared by both delivery paths | pubsub_service.rs:153 | ✅ |
+| `retry::on_codes` substring filter (empty = retry every throw) | retry.rs::on_codes | ✅ |
-| Dashboard Topics tab with **prominent external badge + flip confirmation** | dashboard/.../+page.svelte topics tab | ✅ Per §5 design-notes commitment |

-## 3. The §4-vs-§8 ordering contradiction (HANDBACK §9 #1)
+## 3. The seven flagged deviations (HANDBACK §7)
 
-The brief literally contradicted itself. §4 said:
+### D1. `retry::with` → `retry::run` (Rhai reserved keyword)
 
-> "Order: realtime broadcast FIRST (fast, in-memory), then transactional outbox fan-out (slower)."
+`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.
 
-§8 said:
+**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).
 
-> "Order matters: 1. Validate. 2. Transactional fan-out to outbox. 3. Commit. 4. Non-transactional broadcast to in-process subscribers."
+### D2. Trait move skipped (was plan §5)
 
-The agent picked §8 (broadcast AFTER outbox commit) and explicitly flagged the contradiction in HANDBACK §9 #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).
 
-**§8 is correct.** Three reasons:
+**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.
 
-1. **Correctness over latency.** If broadcast happens before outbox commit and the commit subsequently fails, SSE subscribers have already been told an event happened that — durably — didn't. They can't replay the apology. §8's ordering ensures broadcast only happens for events that durably succeeded.
+### D3. Retry columns on parent triggers row only (was plan §1)
 
-2. **§8 is the dedicated, numbered, rationale-backed section.** §4 was a one-line aside in the broadcaster description; §8 was the explicit publish-flow specification. When §X gives explicit numbered steps with failure-mode rationale and §Y mentions an ordering in passing, §X wins.
+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. **The agent's failure-mode analysis is right.** Per [pubsub_service.rs:170-173](crates/manager-core/src/pubsub_service.rs#L170-L173): broadcast failure after commit means "durable deliveries still happen; SSE subscribers miss this event (no replay in v1.1.6)." Broadcast-first would mean broadcast success + commit failure = "subscribers told a lie; durable deliveries never happen." The latter is strictly worse.
+**Verdict: accept; the brief was wrong here.** Single source of truth on the parent is correct. The agent surfaced this per discipline reminder #2.
 
-**Verdict: confirm §8.** The agent acted on the v1.1.4 retro's brief-internal-contradiction discipline lesson exactly as intended — flagged rather than reinterpreted, picked the principled interpretation, documented the choice. This is the right behavior; the lesson stuck.
+### D4. `Limits::trigger_depth_max` (was plan §5)
 
-The v1.1.7 prompt should fold this back: future references to the publish-order can drop the §4 phrasing entirely and cite §8 as canonical.
+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.
 
-## 4. Latent finding: `dead_letter` handlers never fire (HANDBACK §10)
+**Verdict: accept.** Right level of abstraction — depth check inside `Engine` doesn't reach into `TriggerConfig`.
 
-**Verified.** Grepping for `list_matching_dead_letter` callers:
+### D5. One-consumer-per-queue via advisory lock
 
-```
+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.
-crates/manager-core/src/outbox_event_emitter.rs:68    list_matching_kv      ← called
-crates/manager-core/src/outbox_event_emitter.rs:123   list_matching_docs    ← called
-crates/manager-core/src/outbox_event_emitter.rs:184   list_matching_files   ← called
-                                                       list_matching_dead_letter ← NO PRODUCTION CALLER
-```
 
-`TriggerRepo::list_matching_dead_letter` is defined in the trait (trigger_repo.rs:356), implemented for Postgres (trigger_repo.rs:947), and exists in test fakes (triggers_api.rs:830). But no code path in the dispatcher or the emitter calls it. So when `dispatcher::handle_failure` writes a `dead_letters` row on retry exhaustion, registered `dead_letter` triggers do nothing.
+**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`.
 
-This is a real bug from v1.1.1. The design notes §4 specified dead_letter triggers as a shipped v1.1.1 feature; the wiring was never connected. v1.1.2/v1.1.3/v1.1.4/v1.1.5 all shipped without anyone noticing — likely because:
+### D6. `invoke()` exposed globally (not `invoke::*`)
-- The trait + impl exist (so static analysis doesn't flag dead code).
-- v1.1.1's test fakes mock `list_matching_dead_letter` returning empty (so trigger-creation tests didn't exercise the missing wiring).
-- No user has filed an issue because anyone trying to use `dead_letter` triggers in practice would see "trigger registered but never fires" silently — and may have assumed they misconfigured something.
 
-**The agent's handling is exactly right:**
+The brief itself spelled `invoke(target, args)` not `invoke::call(target, args)`. Registered via `engine.register_global_module(...)`.
-- Surfaced in HANDBACK §10 with the specific code paths.
-- Did NOT attempt a fix (out of v1.1.6 scope).
-- Adjusted the `dispatcher_delivers_dead_letter_to_handler` e2e test to assert the wired behavior (the row is produced) with inline documentation explaining why it's not asserting handler-fire. This is the honest test for what the code currently does.
 
-**For v1.1.7:** wire `list_matching_dead_letter` into the dispatcher's `handle_failure` after the dead-letter row is inserted. The recursion-stop rule from v1.1.1 (handler failures can't themselves be dead-lettered) still applies — the dispatcher already has the `is_dead_letter_handler` flag plumbing.
+**Verdict: accept; the brief was self-consistent here.** Scripts write `invoke("worker", #{...})` which matches the brief example.
 
-**For deployments:** this bug has been silently shipped since v1.1.1. Anyone running v1.1.1–v1.1.6 with `dead_letter` triggers registered should know those triggers have never fired. The fix in v1.1.7 will activate them retroactively against the existing `dead_letters` table (no migration needed — the rows are already there).
+### D7. `invoke_async` runs once (synthetic `retry_max_attempts = 1`)
 
-Worth a CHANGELOG.md callout in v1.1.7 alongside the fix, similar to how v1.1.3's cross-app trigger gap got a retroactive security note.
+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: not a v1.1.6 blocker.** The bug predates this release; v1.1.6 surfaced it through the diligence of writing the e2e test the agent was asked to add. Excellent defensive work.
+**Verdict: accept.** Surfaced misfires through the dead-letter path; callers retain explicit retry control via `retry::run`.
 
-## 5. Test count discrepancy
+## 4. Substantive strengths
 
-HANDBACK §8 attests `cargo test --workspace → 482 passed`. My re-run on the same HEAD reports **~550 passed**. Counting the unique `test result: ok. N passed` lines:
+**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. 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.
-manager-core         256   (was 229 in v1.1.5 → +27)
-executor-core/sdk_*  15+15+8+8+7+5+1+1+17 = 77
-orchestrator-core    74    (was 62 → +12; realtime SSE + broadcaster + key cache tests)
-stdlib               43
-sdk_contract         30
-modules              23
-picloud              21    (incl. 6 dispatcher_e2e skipping no-op)
-schema_snapshot      1
-shared/pubsub        6 (or somewhere thereabouts)
-files-related        20
-                     ───
-                     ~550
-```
 
-The agent's 482 count was likely a snapshot taken before the final commit added a test file, or a `cargo test --workspace 2>&1 | grep -c "passed"` (counts lines, not values) misread. Either way:
+**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.
 
-- The discrepancy is in **the count, not the outcome**: 0 failed, 0 ignored unexpected.
+**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.
-- The gates exit 0; clippy is clean; fmt is clean.
-- The implementation passes every named-critical test from the prompt's §13.
 
-**Verdict: minor accounting drift, not a blocker.** Flag for the v1.1.7 retro: the §8 attestation should be the literal `cargo test --workspace` final-line output (`X passed in Y crates`) or a sum verified by `awk '/test result: ok/ { sum += $4 } END { print sum }'`, not a hand count.
+**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. Substantive strengths
+**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.
 
-**1. Streaming-`fetch` SSE in the client lib was the right call.** Native `EventSource` can't set custom auth headers (forcing the `?token=` query-string path, which the server still supports as an EventSource-compat option). But for the client lib, dropping EventSource in favor of streaming `fetch` unlocks three things at once: bearer-header auth (cleaner than query-string), 401 detection on (re)connect → `onTokenExpired` callback → token refresh → reconnect, and `Last-Event-ID` resume header (server ignores it in v1.1.6 but the client ships ready). Trade-off: requires `fetch` streaming, so React Native needs a polyfill — the README documents this. Right trade for v1.1.6's target audience.
+**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.
 
-**2. The HMAC-signing-key persisted-table choice avoids a global secret.** The agent took the recommended path: per-app 32-byte random keys in `app_secrets`. No `PICLOUD_INSTANCE_SECRET` env var to operate. Future v1.1.7 encrypted-per-app-secrets work has its natural home. The cost — one DB read per subscribe — is mitigated by the in-process key cache (correct in v1.1.6 because keys never rotate; HANDBACK §12 flags the rotation-invalidation requirement for future).
+## 5. Open questions answered
 
-**3. Defense in depth on cross-app isolation.** Per-app signing key + explicit `claims.app_id == app_id` check + broadcaster channels keyed by `(AppId, topic)`. Any single guard would suffice; all three together make the boundary obvious in code AND impossible to bypass via a single mistake.
+HANDBACK §9 raises four:
 
-**4. Three v1.1.5 follow-ups all landed.** The empty-blob relaxation, the orphan tmp-sweeper, the six dispatcher e2e tests. All in this release, not deferred. The e2e tests are gated on `DATABASE_URL` cleanly via early-return (matches the v1.1.5 schema_snapshot pattern); CI's Postgres service exercises them.
+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.
 
-**5. The agent's discipline carryover is exemplary.** Both flagged items (§4-vs-§8 contradiction, dead_letter latent finding) were caught by the v1.1.4 + v1.1.3 retro discipline lessons: brief-internal contradictions get flagged-not-reinterpreted, latent security/correctness findings get their own HANDBACK section. The §8 attestation was taken on the actual HEAD with the explicit "this HANDBACK commit is pure markdown" footnote. Every deviation is in §7. The system is working.
+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).
 
-**6. Commit split.** Three commits — realtime+followups+versions, client lib, handback. Cleaner than v1.1.5's three substantive (because the client lib genuinely is a standalone artifact in a different toolchain), and the build-app cross-crate constraint that drove a single big realtime commit is honestly documented in HANDBACK §7 #1.
+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.
 
-## 7. Smaller observations (no action required)
+4. **Cluster-mode reclaim coordination.** Out of scope per the brief; v1.3+ cluster work will need advisory-lock coordination for the reclaim task.
 
-- **Dispatcher e2e location deviation (HANDBACK §7 #1).** Brief said `crates/manager-core/tests/`; agent put them in `crates/picloud/tests/` because `build_app` lives there. The cycle the agent describes (manager-core → picloud dev-dep) is real. The picloud location is correct — `build_app` is where the dispatcher + scheduler + executor are wired into one stack, and that wiring is what the e2e tests need to exercise.
+## 6. Smaller observations
-- **Empty-blob relaxation extended to `FileUpdate::validate` (HANDBACK §7 #2).** The brief only named `NewFile::validate`. Extending to update is correct — relaxing create-empty but rejecting update-to-empty would be an inconsistent API.
-- **Topic-name validation (HANDBACK §7 #4).** Small defensive add: empty names and names containing `*` rejected at admin endpoint. Defends against operator confusion when topic-pattern external subscription lands in v1.2 (preemptive: `*` will mean something there, so reserving it now avoids a future breaking validation).
-- **Client lib lint via `tsc --noEmit` instead of eslint (HANDBACK §7 #5).** Right call for v1.1.6 — strict TS does most of what eslint would, and adding eslint configuration is a separate scope of work. Easy to add later if there's a real type-system-can't-catch-it lint rule we need.
-- **Cron e2e 45s poll budget (HANDBACK §7 #6).** Defensive against the default 30s tick interval; CI sets `PICLOUD_CRON_TICK_INTERVAL_MS=1000` to make it ~2s. Reasonable.
-- **`broadcast::Sender` shape vs `oneshot::Sender`.** v1.1.1's `InboxRegistry` uses oneshot (single delivery). v1.1.6's broadcaster uses `tokio::sync::broadcast` (repeated delivery to multiple receivers). Different patterns for different problems; the trait split in shared keeps both Cluster-mode-swappable.
 
-## 8. Versioning audit
+- **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.

Add a call to `list_matching_dead_letter` in `dispatcher::handle_failure` after the row is inserted, enqueue an outbox row per matching trigger with `source_kind: 'dead_letter'` and the appropriate `TriggerEvent::DeadLetter` payload. The recursion-stop rule (handlers can't be dead-lettered) is already implemented; the wiring just isn't connected. Plus a CHANGELOG retroactive note covering v1.1.1–v1.1.6 ("dead_letter triggers were registerable but never fired; this release activates them against existing dead_letters rows, no migration needed").
+   - **`ctx.trigger_depth` surface in the Rhai `ctx` map** (5-line addition per HANDBACK §9 #3).
-   - **Encrypted per-app secrets.** v1.1.7's brief topic. The `app_secrets` table from v1.1.6 is the natural home; the realtime signing key already lives there. v1.1.7's encrypted-secrets work should extend the table (or add a sibling) for general per-app secrets.
+   - **`invoke()` method-aware route resolution** (POST→GET fallback today; explicit method arg per HANDBACK §9 #2).
-   - **§8 attestation discipline refinement:** require the §8 attestation be sourced from `cargo test --workspace 2>&1 | tail` rather than a hand count (per §5 above).
+   - **AST cache reuse across `invoke()` calls** (D2 deferred optimization).
-   - **The brief-internal-contradiction discipline lesson stuck.** v1.1.7's brief should be walked through for example/spec contradictions before dispatch, same as the v1.1.5 retro lesson the v1.1.6 brief honored. Keep doing this.
+   - **Permission matrix design for `users::*` roles** — v1.1.8 follow-up that's been waiting for the v1.2 design conversation.
-5. **For the v1.1.8 dispatch prompt** (User Management): the `app_secrets` table + the `RealtimeAuthority` trait shape are ready for v1.1.8 to add `auth_mode = 'session'` as the third subscriber-auth flavor (extending the CHECK constraint, adding a session-token validator alongside the existing HMAC validator behind the unchanged trait).
+   - **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").

+# PiCloud Security Audit — 2026-06-11
+
+10 parallel focused subagents reviewed the codebase at `main` (post-v1.1.9, pre-v1.2) for vulnerabilities in their assigned category. Each agent wrote a detailed findings file under [`security_audit/`](security_audit/); this document is the rollup.
+
+## Scope and method
+
+Each agent traced specific code paths end-to-end, cited file + line, classified by severity, and recommended a concrete fix. 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.

+10. [10_info_disclosure_cli.md](security_audit/10_info_disclosure_cli.md) — error response bodies, log redaction, CLI token files, dashboard token storage
+
+## 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.

+//! `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.

+//!     backoff: "exponential",  // "exponential" | "linear" | "constant"
+//!     base_ms: 500,

+//! // Optional error-code filter:
+//! let p2 = retry::on_codes(p, ["http: 503", "http: 504"]);
+//! ```
+//!
+//! NOTE: the brief called for `retry::with(policy, closure)` but `with`
+//! AND `call` are both Rhai reserved keywords (rejected at the parser
+//! 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.

+-- (`cx.app_id`) — the same "group template runs under the firing app" model.
