docs(v1.1.3): reviewer audit report — APPROVE verdict

Audit of feat/v1.1.3-modules against the v1.1.3 dispatch prompt.
All three gates green on HEAD; 358 tests pass, 140 properly ignored.
Cross-app isolation in PicloudModuleResolver verified airtight,
RAII guard pattern for stack+depth cleanup audited line-by-line,
version-keyed cache invalidation model accepted as correct.

Three deviations from the prompt reviewed: depth-limit default 8
instead of 32 (silent change — discipline note for next retro,
but the choice is defensible), module-name CHECK and reserved-name
list (both net improvements not in the prompt), ScriptValidator
trait shape change (bounded blast radius, required by dep-graph
design).

Latent cross-app security gap in v1.1.1/v1.1.2 trigger creation
closed as part of this release — backport awareness flagged for
the retro.

 # PiCloud Changelog
 
+## v1.1.3 — Modules (unreleased)
+
+Real per-app Rhai module system. Scripts can `import "<name>" as
+<alias>;` other scripts in the same app as reusable libraries. The
+v1.0 placeholder `DummyModuleResolver` is replaced by a per-call
+`PicloudModuleResolver` that loads `kind = 'module'` scripts via a
+new `ModuleSource` trait, compiles them into Rhai modules, caches
+the compiled output, and enforces cross-app isolation, circular-
+import detection, and an import-depth limit. Two LRU AST caches
+(top-level script + per-module compiled module) eliminate the
+per-invocation compile cost; both invalidate on `updated_at` change.
+
+### Added
+
+- **`scripts.kind` column** — `'endpoint' | 'module'`, default
+  `'endpoint'`. Endpoints handle HTTP routes / trigger events;
+  modules are libraries imported by other scripts. The dashboard
+  scripts list + script detail page surface the distinction as a
+  colored badge.
+- **`script_imports` dep-graph table** — populated at script save-
+  time from the literal-path `import "<name>"` declarations in the
+  source. FK-CASCADE on both columns. No admin surface in v1.1.3
+  (drives a v1.2+ "Used by" dashboard panel and v1.3+ cluster-mode
+  eager invalidation).
+- **`ModuleSource` trait** — `lookup(&SdkCallCx, name)`. Postgres
+  impl `PostgresModuleSource` in manager-core. `app_id` derived from
+  `cx.app_id` (cross-app isolation boundary, mirrors KV / docs).
+- **`PicloudModuleResolver`** — implements `rhai::ModuleResolver`.
+  Per-call instance owns `Arc<SdkCallCx>`, the in-progress imports
+  stack, the depth counter. Bridges sync `resolve()` to async
+  `lookup()` via `Handle::block_on` (safe under the executor's
+  `spawn_blocking` wrap). Replaces `DummyModuleResolver` at line 139
+  of `executor-core::engine::build_engine`.
+- **Module-shape validation** — `kind = 'module'` source must contain
+  only `fn` declarations, `const` declarations, and `import`
+  statements at top level (no executable expressions). Walks
+  `ast.statements()` via `rhai/internals`. Admin endpoint is the
+  primary gate; the resolver re-runs the check at load time for
+  defense in depth against DB-direct inserts.
+- **Per-module compiled-Module cache** — `LruCache<(AppId, name),
+  (updated_at, Arc<rhai::Module>)>` owned by `Engine`. Invalidated
+  lazily on `updated_at` mismatch. Size via
+  `PICLOUD_MODULE_CACHE_SIZE` (default 512).
+- **Top-level script AST cache** — `LruCache<ScriptId, (updated_at,
+  Arc<rhai::AST>)>` owned by `LocalExecutorClient`. Same staleness
+  semantics. Size via `PICLOUD_SCRIPT_CACHE_SIZE` (default 256).
+- **`ScriptIdentity` + `ExecutorClient::execute_with_identity`** —
+  new method on the trait; default impl forwards to `execute` so
+  `RemoteExecutorClient` (and future transports) keep working.
+  `LocalExecutorClient` overrides it to consult the script cache and
+  pass the resulting `Arc<rhai::AST>` to `Engine::execute_ast`.
+- **`Engine::execute_ast`** — companion to `execute` that takes a
+  pre-compiled AST so callers (the orchestrator) can reuse one
+  compile across many invocations.
+- **Import depth limit** — `Limits::module_import_depth_max`
+  (default 8). Not script-overridable.
+- **Reserved module names** — module-kind scripts cannot be named
+  `log`, `regex`, `random`, `time`, `json`, `base64`, `hex`, `url`,
+  `kv`, `docs`, `dead_letters`, `http`, `files`, `pubsub`, `secrets`,
+  `email`, `users`, `queue`. Defense against author confusion with
+  stdlib namespaces.
+
+### Changed
+
+- **Workspace version**: `1.1.2` → `1.1.3`.
+- **Rhai SDK version**: `1.3` → `1.4` (additive — every v1.3 script
+  still runs unchanged; new surface: `import "<name>" as <alias>;`
+  for endpoint scripts that consume modules in the same app).
+- **Dashboard version**: `0.8.0` → `0.9.0`. Adds kind dropdown on
+  script create + kind badges on the scripts list and detail page.
+- **`Services` bundle** — grows a `modules: Arc<dyn ModuleSource>`
+  field. Constructor signature becomes
+  `Services::new(kv, docs, dead_letters, events, modules)`.
+- **`ScriptValidator` trait** — `validate` now returns
+  `ValidatedScript { imports: Vec<String> }` so the repo can write
+  dep-graph edges in the same transaction as the script row. New
+  `validate_module` method enforces module-shape rules.
+- **Trigger creation tightening** — `POST /api/v1/admin/apps/{id}/triggers/{kv,docs,dead_letter}`
+  now load the target script and reject when (1) it doesn't exist,
+  (2) it belongs to a different app (latent v1.1.1/v1.1.2 gap —
+  closed in v1.1.3), or (3) it is `kind = 'module'`.
+- **Route creation** — `POST /api/v1/admin/scripts/{id}/routes`
+  returns 400 when the target script is `kind = 'module'`.
+
+### Migrations
+
+- `0015_scripts_kind.sql` — adds `scripts.kind` with CHECK
+  `IN ('endpoint','module')`, composite index `(app_id, kind)`, and
+  a module-name shape CHECK (`^[a-zA-Z_][a-zA-Z0-9_]{0,63}$`).
+- `0016_script_imports.sql` — adds the dep-graph table with FK
+  CASCADE on both columns, PK `(importer, imported)`, and a
+  reverse-edge index on `imported_script_id`.
+
+### Downgrade caveats
+
+Rolling back v1.1.3 → v1.1.2 with module-kind scripts present
+strands them (no `kind` column means everything looks like an
+endpoint; modules will then succeed as route targets and immediately
+fail to execute meaningfully). Migration `0016_script_imports.sql`
+is safe to drop (the table is auxiliary). `0015_scripts_kind.sql`
+must be reversed by `DROP COLUMN kind` only after manually re-homing
+or deleting module-kind rows.
+
+## v1.1.2 — Documents (unreleased)
+
+`docs::*` SDK — schemaless JSONB document storage with a first-cut
+query DSL — plus `docs:*` triggers as the second concrete kind on the
+v1.1.1 triggers framework. Sets the precedent for the v1.2 query DSL
+expansion and `dead_letters::list`.
+
+### Added
+
+- **Docs store** — `docs` table keyed `(app_id, collection, id)` with
+  JSONB values and a GIN-on-`jsonb_path_ops` index. Rhai SDK exposes
+  the handle pattern:
+  `docs::collection(name).{create,get,find,find_one,update,delete,list}`.
+  Cursor-style pagination on `list`. Cross-app isolation enforced via
+  `cx.app_id` (never script-passed). Document envelope shape returned
+  by reads: `#{ id, data: #{...}, created_at, updated_at }` — explicit
+  metadata + user-data separation (sets precedent for v1.2
+  `dead_letters::list`).
+- **Query DSL (v1.1.2 subset)** — implicit equality at top level
+  (`#{ tier: "gold" }`), operator-object form
+  (`#{ created_at: #{ "$gt": "..." } }`), dotted field paths up to 5
+  levels (`"user.email"`), and operators `$eq`/`$ne`/`$gt`/`$gte`/
+  `$lt`/`$lte`/`$in`. Filter modifiers `$sort` (single field) and
+  `$limit`. Unsupported operators (`$or`, `$regex`, etc.) reject with
+  a clear v1.2-pointer error.
+- **Docs triggers (`docs:*`)** — `docs_trigger_details` table mirrors
+  `kv_trigger_details`. Admin endpoint
+  `POST /api/v1/admin/apps/{id}/triggers/docs` accepts the same DTO
+  shape as the KV endpoint with `ops` of `DocsEventOp` (create /
+  update / delete). Dispatcher routes `OutboxSourceKind::Docs` through
+  the same generic path as KV + dead-letter.
+- **`ctx.event.docs.prev_data`** — change-data-capture surface for
+  docs trigger handlers. `prev_data` carries the document state prior
+  to the mutation (`None` for create), letting handlers see what
+  changed. The repo reads the old row in the same SQL statement as
+  the write so the trigger event has the prior value.
+- **`Capability::AppDocsRead(AppId)`** + `AppDocsWrite(AppId)` —
+  granted to Viewer / Editor respectively in the per-app role table.
+  Same trust shape as KV's `AppKvRead` / `AppKvWrite`.
+
+### Changed
+
+- **Workspace version**: `1.1.1` → `1.1.2`.
+- **Rhai SDK version**: `1.2` → `1.3` (additive — every v1.2 script
+  still runs unchanged; new surfaces: `docs::collection(name).{...}`,
+  `ctx.event.docs` for triggered handlers).
+- **Dashboard version**: `0.7.0` → `0.8.0`. Workspace alignment; no
+  docs-specific UI in v1.1.2 (the dashboard's Rhai-mode hints don't
+  list KV completions either — focused UX pass is a separate task).
+- **`Services` bundle** — grows a `docs: Arc<dyn DocsService>` field.
+  Constructor signature becomes
+  `Services::new(kv, docs, dead_letters, events)`.
+- **Scope mapping**: API keys with `script:read` scope can call
+  `docs::find` / `get` / `list`; `script:write` can call
+  `docs::create` / `update` / `delete`. Same trust shape as KV —
+  honors the seven-scope commitment from v1.1.0.
+
+### Migrations
+
+- `0013_docs.sql` — `docs` table + per-`(app_id, collection)` index +
+  GIN-on-`jsonb_path_ops` index.
+- `0014_docs_triggers.sql` — extends `triggers.kind` and
+  `outbox.source_kind` CHECK constraints to include `'docs'`; adds
+  `docs_trigger_details` table.
+
+### Downgrade caveats
+
+Rolling a deployment back from v1.1.2 → v1.1.1 with `docs`-source
+outbox rows still queued will cause the v1.1.1 dispatcher to fail
+deserialising `TriggerEvent::Docs` (`#[serde(tag = "source")]`
+rejects unknown variants). Drain or delete
+`outbox WHERE source_kind = 'docs'` before downgrading. Trunk-only
+deployments don't hit this.
+
+### Known limitations
+
+- Text-lex comparison for `$gt` / `$gte` / `$lt` / `$lte` is
+  incorrect for unpadded numbers crossing digit-count boundaries
+  (`'10' < '9'` is TRUE under any text collation). Workaround:
+  zero-pad numeric strings. v1.2's advanced query expansion adds
+  numeric-aware operators.
+- Concurrent `update()`s on the same doc may both emit the
+  pre-update `prev_data` (last-writer-wins). Inherited from KV's
+  `set` pattern; documented for forensic-trace use cases.
+- v1.1.2 has no partial-update DSL — scripts that want partial
+  update do `get + modify + update`. Planned for v1.2.

 ## Working Rules
 
-- **Honor the three-service boundary.** Don't reach across `*-core` crates. If `orchestrator-core` needs something from `manager-core`, define a trait in `shared` and inject the impl.
+- **Honor the three-service boundary.** Don't reach across `*-core` crates *for behavior*. If `orchestrator-core` needs to invoke logic from `manager-core`, define a trait in `shared` and inject the impl — keep implementations decoupled. **Transport DTOs are not behavior**: types like `ExecRequest` / `ExecResponse` / `ExecError` represent values produced or consumed across the wire, and depending on the originating crate's type definitions is fine. The bright line is "don't call across crates," not "don't import types." When in doubt: if the imported item is a `struct`/`enum`/`type alias` with no methods (or only data-shape methods), it's a DTO and crossing is fine; if it's a trait, function, or service, define the abstraction in `shared` and inject.
 - **`executor-core` has no Postgres dependency.** Data-plane services (kv, docs, users — v1.1+) come in via injected `ServiceProvider` traits.
 - **Database writes only from `manager-core`.** `orchestrator-core` reads scripts (cached); `executor-core` doesn't touch the DB.
 - **Stateful SDK services use the handle pattern + `SdkCallCx`.** Collection-scoped surfaces look like `kv::collection("x").get(k)`, not `kv::get("x", k)`. Every service trait method takes `&SdkCallCx` and **MUST** derive `app_id` from `cx.app_id` — never trust a script-passed `app_id`. That is the cross-app isolation boundary. See [docs/sdk-shape.md](docs/sdk-shape.md).

-## 2. Scope coverage (Done / Partial / Skipped)
-
-| Scope item | Status | Notes |
-|---|---|---|
-| **1. KV store** | Done | Migration 0007, `KvService` trait in shared, `KvServiceImpl` + `PostgresKvRepo` in manager-core, Rhai `kv::collection(name).{get,set,has,delete,list}` bridge, cursor pagination, empty-collection rejection, script-as-gate authz. |
-| **2. Triggers framework — Layout E** | Done | Migrations 0008 (`triggers` + `kv_trigger_details` + `dead_letter_trigger_details`), `TriggerRepo` + `PostgresTriggerRepo`, CRUD admin endpoints. `registered_by_principal` column captured + threaded into the dispatcher. Depth-limit enforced in the dispatcher (default 8). |
-| **3. Universal outbox + dispatcher** | Done | Migration 0009 (`outbox`), `OutboxRepo` + `PostgresOutboxRepo`, `Dispatcher` tokio task. Polls every 100ms, claims 8 rows/tick via `FOR UPDATE SKIP LOCKED`, gate-bounds dispatch, retries with backoff+jitter, dead-letters on exhaustion, late-completion → `abandoned_executions`. |
-| **4. NATS-style sync HTTP** | Done | `InboxRegistry` in orchestrator-core (in-process `Mutex<HashMap<Uuid, oneshot::Sender>>`), `InboxResolver` trait in shared. Orchestrator sync-route path registers receiver, writes outbox row with `reply_to`, awaits with timeout = script.timeout + 2s buffer. Status mapping per design notes §3 (422/502/503/504/507/500). |
-| **5. `dispatch_mode: async` HTTP routes** | Done | Migration 0012 adds the column (default `sync`). `DispatchMode` enum in shared. Route admin payload + RouteRepository serialize it. Compiled routes carry it; the matcher returns it in `Matched`. Orchestrator branches: async → outbox + 202; sync → outbox + inbox. |
-| **6. Dead letters** | Done | Migration 0010 (`dead_letters`), `DeadLetterRepo` + `DeadLetterService` + `PostgresDeadLetterService`. Rhai `dead_letters::{replay,resolve}` + admin endpoints (`GET /count`, `GET /`, `GET /{id}`, `POST /{id}/replay`, `POST /{id}/resolve`). `Capability::AppDeadLetterManage(AppId)` enforced. List intentionally NOT shipped (deferred to v1.2). Recursion-stop rule (handler-failure annotates original DL as `handler_failed`) implemented in the dispatcher. |
-| **7. Abandoned executions** | Done | Migration 0011, `AbandonedRepo` + `PostgresAbandonedRepo`, dispatcher writes a row on dropped-receiver inbox delivery. Metric path reserved (`TODO(metrics)` markers in dispatcher.rs). |
-| **8. Retry policy defaults** | Done | `TriggerConfig::from_env` (new module). Env vars: `PICLOUD_MAX_TRIGGER_DEPTH`, `PICLOUD_TRIGGER_RETRY_{MAX_ATTEMPTS,BACKOFF,BASE_MS,JITTER_PCT}`, `PICLOUD_DEAD_LETTER_RETENTION_DAYS`, `PICLOUD_ABANDONED_EXECUTIONS_RETENTION_DAYS`. Per-trigger overrides applied at trigger-creation time. |
-| **9. `ctx.event` for triggered scripts** | Done | `TriggerEvent` enum in shared (KV / DeadLetter variants), `SdkCallCx.event: Option<TriggerEvent>` + `is_dead_letter_handler: bool`. `engine.rs::build_ctx_map` flattens the event into `ctx.event` for triggered handlers; direct invocations leave the key absent. Shape matches design notes §4 (KV with op + collection + key + value; dead_letter with original + attempts + last_error + ids + timestamps). |
-| **10. Dashboard surface** | Done | Per-app red badge with unresolved count on apps list + per-app detail page. New `apps/[slug]/dead-letters/+page.svelte` list view with all design-notes-mandated columns + Replay + Mark resolved actions + expandable row detail. svelte-check passes (369 files, 0 errors, 0 warnings). |
-| **11. Workspace version bump** | Done | Workspace `1.1.0` → `1.1.1`, SDK `1.1` → `1.2`, dashboard `0.6.0` → `0.7.0`. CHANGELOG.md created at repo root. |

-## 3. Key implementation decisions / deviations
-
-### Outbox column set (deferred to implementation per design notes §2)
-Chose:
-- `script_id` denormalized — dispatcher resolves the target without
-  re-joining for the common path.
-- `trigger_id` polymorphic (no DB FK) — references `triggers.id` for
-  `source_kind IN {kv, dead_letter}`, `routes.id` for
-  `source_kind = 'http'`. Discrimination in Rust at dispatch time.
-- `claimed_by TEXT` — pid-based for MVP; cluster mode can use any
-  identifier without schema change.
-- `trigger_depth` + `root_execution_id` denormalized so the
-  dispatcher rebuilds `ExecRequest` without joining back to the
-  originating execution log.
-- No explicit `is_dead_letter_handler` column — dispatcher infers
-  from the trigger's `kind` field at dispatch time.
-
-### KV pagination
-- **Cursor-style**, opaque base64-encoded last-key.
-- Page-size cap of 1000 with default 100 (enforced in repo).
-- Documented in `crates/shared/src/kv.rs` and the SDK function
-  comment.
-
-### KV TTL
-- Blueprint §8.1 reserved an `expires_at` column. v1.1.1 design notes
-  don't surface TTL through the SDK (`set(k,v)` has no TTL argument)
-  so the column is **omitted from migration 0007**. Adding it later
-  is a non-breaking forward migration. Recorded in CHANGELOG as a
-  deferred item.
-
-### Authz scope mapping (seven-scope commitment)
-The four new capabilities map onto existing scopes — **no new scope
-variants** to honour the `Scope` enum's "exactly seven values"
-contract (`crates/shared/src/auth.rs:103`):
-
-| Capability | Scope |
-|---|---|
-| `AppKvRead` | `script:read` |
-| `AppKvWrite` | `script:write` |
-| `AppManageTriggers` | `app:admin` |
-| `AppDeadLetterManage` | `app:admin` |
-
-`role_satisfies` grants `AppKvRead` at the Viewer role, `AppKvWrite`
-at Editor, and both trigger / DL caps at AppAdmin.
-
-### Script-as-gate authz for SDK calls
-- `KvServiceImpl` runs `authz::require` only when
-  `cx.principal.is_some()`. Anonymous public-HTTP scripts (the
-  common case for public routes) bypass the cap check.
-- Cross-app isolation is **independent** of this — enforced by
-  `cx.app_id` being the only source of `app_id` on every query.
-- `PostgresDeadLetterService::{replay,resolve}` keeps a hard
-  `require` (no `if let Some`) — managing dead letters is an admin
-  act per design notes §4. Public scripts with `principal: None`
-  fail the check, which is correct.
-
-### Trait split: `OutboxRepo` vs `OutboxWriter`
-orchestrator-core can't depend on manager-core (would invert the
-dependency arrow). Defined a small `OutboxWriter` trait in
-`picloud-shared` with a single `enqueue_http` method.
-`PostgresOutboxRepo` implements both `OutboxRepo` (dispatcher
-surface) and `OutboxWriter` (orchestrator surface); the picloud
-binary clones one concrete Arc into both trait views — mirrors the
-existing `members_concrete` / `AuthzRepo` pattern.
-
-### `InboxResolver` lives in shared, `InboxRegistry` in orchestrator-core
-Same split rationale — the dispatcher (manager-core) only depends on
-the trait, while the in-process impl lives next to its consumer.
-Cluster mode (v1.3+) swaps the impl for `LISTEN/NOTIFY` behind the
-unchanged trait.
-
-### manager-core now depends on executor-core
-Previously manager-core only depended on orchestrator-core. The
-dispatcher needs `ExecRequest`/`ExecResponse`/`ExecError`/
-`InvocationType` from `executor-core` to build invocation
-descriptors. This is the transport DTO interpretation of the
-working-rules "don't reach across `*-core` crates" — DTOs are fine,
-behaviour is the bright line.
-
-### Sync HTTP via outbox is the default for the user-routes path
-The orchestrator's user-route handler is fully on the NATS-style
-path now — every sync HTTP request writes to the outbox and awaits
-inbox delivery. Adds ~2-5ms per request per design notes §3 latency
-budget. `/api/v1/execute/{id}` (the admin/dev bypass) still calls
-the executor directly since it doesn't need the unified
-observability — kept for simplicity and admin tooling speed.
-
-### Trigger-depth check is on the outbox row, not in the executor
-Dispatcher rejects depth-exceeded rows **before** trying to
-execute. The `cx.trigger_depth` field is informational on the
-executor side. Rejection writes a log + (reserved) metric and
-deletes the row — no DL, per design notes §4.
-
-## 4. Tests added
-
-### Unit tests (no DB required)
-- `manager-core::kv_service::tests` (10 tests) — round-trip, missing
-  key returns None, `has` predicate, `delete` was-present,
-  empty-collection rejection, **cross-app isolation**, anonymous-cx
-  skips authz, authed-cx-with-no-role is Forbidden, owner-can-write,
-  cursor pagination via in-memory KvRepo + denying authz repo.
-- `manager-core::trigger_config::tests` (2 tests) — conservative
-  defaults, backoff round-trips.
-- `manager-core::trigger_repo::tests` (1 test) — `collection_matches`
-  glob behaviour (`*`, `prefix:*`, exact).
-- `manager-core::dispatcher::tests` (5 tests) — exponential / linear /
-  constant backoff math, jitter within bounds, ExecError →
-  InboxFailureKind classification, failure-kind → status-code mapping.
-- `manager-core::abandoned_repo::tests` (2 tests) — truncate
-  char-boundary safety.
-- `manager-core::triggers_api::tests` (5 tests) — unknown-app 404,
-  member-without-role 403, default fallback for retry settings,
-  empty-glob rejection, cross-app delete is treated as not-found.
-- `orchestrator-core::inbox::tests` (4 tests) — register/deliver
-  round-trip, unknown-id is Abandoned, dropped receiver is
-  Abandoned, explicit cancel removes sender.
-- `executor-core::engine::tests` (3 new) — `ctx.event` absent for
-  direct invocations, KV insert shape matches design notes,
-  KV delete has unit value.
-- `executor-core::sdk_kv` integration suite (7 tests) — runs a real
-  Rhai engine under `spawn_blocking` against an in-memory
-  `KvService` impl. Covers handle pattern, round-trip, unit-on-
-  missing, has predicate, delete-was-present, empty-collection
-  throws, cursor pagination, **cross-app isolation through the
-  bridge**.
-
-**Total: 47 new tests across the workspace.** Workspace test counts
-after v1.1.1: 63 manager-core / 56 orchestrator-core / 17
-executor-core engine / 7 sdk_kv / 30 sdk_contract / 43 stdlib /
-21 picloud / 6 shared.
-
-### Intentionally untested
-- DB-backed integration tests for the full dispatcher loop, KV→
-  trigger→DL retry chain, sync HTTP via outbox round-trip,
-  recursion-stop end-to-end. These need a real Postgres harness;
-  the reviewer runs them via the manual smoke flow below.
-- Postgres-specific repo behaviour (sqlx query correctness). The
-  repos compile and run against the schema, but no integration
-  test crate spins up a DB in this branch — same pattern as v1.1.0
-  (see existing `ignored, needs DATABASE_URL` test markers).
-
-## 5. Open questions for the reviewer
-
-1. **Outbox `claimed_at` clearing on success.** The dispatcher
-   `delete`s the outbox row after success / DL. For failures it
-   reschedules (which sets `claimed_at = NULL`). Both flows are
-   correct, but if you imagine a crash between the executor return
-   and the row update, the row stays claimed forever. Cluster mode
-   should add a periodic "unstick stale claims" sweep. Not in
-   v1.1.1 scope but worth surfacing.
-2. **Sync HTTP overhead.** Every sync HTTP request now goes through
-   the outbox (write + dispatcher pickup + inbox delivery).
-   Measured overhead expected ~2-5ms per design notes §3. No
-   benchmarking yet — recommend the reviewer pick a representative
-   script and compare 95p latency vs v1.1.0 if performance matters.
-3. **HTTP outbox rows don't run as a principal.** The orchestrator's
-   public HTTP path has no authenticated user; the
-   `origin_principal` field on the outbox row is forensic. The
-   resulting `ExecRequest.principal = None`, so the script runs
-   anonymously — matches direct execution. If you'd prefer
-   triggered-from-HTTP scripts to inherit a derived principal
-   (e.g. the route's app's owner), that's an additive change.
-4. **Dispatcher uses `ASYNC_EXEC_TIMEOUT = 300s` for async rows.**
-   Async dispatches don't have a script-level timeout (no
-   originating HTTP request to bound). Picked the same platform
-   cap as `LocalExecutorClient`. If async needs a different cap,
-   easy to thread through `TriggerConfig`.
-5. **Dispatcher tick cadence is 100ms.** Bounded enough that
-   fan-out feels instant; loose enough that an idle process
-   doesn't burn cycles. If the reviewer wants tighter latency,
-   bump to 50ms or use `LISTEN/NOTIFY` for wake-up (v1.3+ work).
-6. **CHANGELOG.md is new.** Followed the rest of the repo's
-   convention from git log (release commits + design-notes
-   references). If a different format is preferred, easy to swap.
-
-## 6. Deferred to later releases
-
-- `dead_letters::list(filter)` Rhai SDK — design notes §4 defers
-  to v1.2 to align with `docs::find()` query DSL.
-- KV TTL (`set(k, v, ttl_secs)`) — blueprint reserved it; v1.1.1
-  SDK doesn't surface it. Forward-compat (no schema cost).
-- Auto-disable of triggers whose script was deleted — design notes
-  §4 says current handling is metric+log; auto-disable is v1.2.
-- Per-app dead-letter retention — design notes §4 says env-only in
-  v1.1.1.
-- Metrics counter emit for `picloud_trigger_depth_exceeded`,
-  `picloud_dead_letter_handler_failures`,
-  `picloud_abandoned_executions_total`. Code paths log the
-  occurrences with `tracing::warn`/`error`; the actual
-  counter-emit code is a `TODO(metrics)` comment in the
-  dispatcher. Metrics surface is v1.1.7+ per the roadmap.
-- DB-backed integration tests for the dispatcher loop (see §4
-  intentionally-untested).
-- Sync HTTP performance benchmarks comparing v1.1.0 direct path vs
-  v1.1.1 outbox path.

-## 7. How to verify locally
-
-### Static checks (all green on this branch)
-```sh
-cargo fmt --all -- --check
-cargo clippy --all-targets --all-features -- -D warnings
-cargo test --workspace
-cd dashboard && npm run check && npm run build
-```
-
-### Migration integrity
-```sh
-docker compose down -v && docker compose up -d postgres
-cargo run -p picloud      # applies 0001..0012 from empty
-```
-Then start from `main` (v1.1.0 schema state) and switch to this
-branch; restart `picloud` to apply 0007..0012 on top.
-
-### Manual end-to-end smoke (reviewer should run)
-```sh
-docker compose up -d
-# 1. Bootstrap an owner user via the existing flow + create app A.
-# 2. Create a script in A whose body is:  throw "boom"
-# 3. POST /api/v1/admin/apps/{A}/triggers/kv with
-#    {"script_id": "<broken>", "collection_glob": "*", "ops": ["insert"]}
-# 4. From another script (or a public HTTP route):
-#    kv::collection("widgets").set("k1", #{n:1})
-# 5. Wait ~7 seconds (3 attempts × ~1/2/4s backoff with ±20% jitter).
-# 6. Open the dashboard at /admin.
-# 7. Apps list shows a red "1" badge next to app A.
-# 8. Click into app A → "Dead letters" tab link → row visible.
-# 9. Click row → full payload + error history.
-# 10. Click "Replay" → row marks resolution='replayed', new outbox
-#     row written, dispatcher re-runs the handler (fails again,
-#     produces a NEW DL row).
-# 11. Click "Mark resolved" on the original DL → resolution='ignored'.
-```
-
-### Async route smoke
-```sh
-# Create a route via POST /api/v1/admin/scripts/{id}/routes with
-# {"host_kind":"any","path_kind":"exact","path":"/work","dispatch_mode":"async"}
-curl -X POST -d '{"work":"thing"}' http://localhost:8080/work
-# Expect: HTTP 202 + {"accepted_at":"...","execution_id":"..."}
-# Then tail execution_logs — the script ran later (not synchronously).
-```
-
-### Trigger-depth limit smoke
-```sh
-# Set a low depth limit + register a KV trigger whose script
-# writes to KV again — creates a loop.
-PICLOUD_MAX_TRIGGER_DEPTH=3 cargo run -p picloud
-# kv.set(...) from a script → triggers same script → depth hits 4
-# Observe: depth-exceeded logged + outbox rows dropped (no DL spam).
-```
-
-## 8. Known limitations / rough edges
-
-- **No DB-backed integration tests in this branch.** Unit tests
-  cover trait behaviour with in-memory backings; sqlx query
-  correctness is verified by the workspace compile + manual smoke.
-- **Dispatcher concurrency is in-process serial-per-tick.** Up to
-  8 rows claimed per tick, processed one at a time. Could be
-  parallelised with per-row `tokio::spawn` — kept serial for MVP
-  predictability (the gate already bounds total concurrent
-  executions globally).
-- **Metric emission is TODO** at the three spots noted in
-  Open Questions §5. The behaviour they would observe is captured
-  via `tracing::warn`/`error` in the meantime.
-- **`PostgresDeadLetterService::replay` doesn't restore the
-  original `trigger_depth`.** Replays start at depth 0. If a DL
-  row was originally produced at depth 7 with `max_trigger_depth=8`
-  and the replayed handler fans out again, it gets the full depth
-  budget. Acceptable for an admin-initiated replay (deliberate
-  retry), but worth noting if the reviewer disagrees.
-- **HTTP outbox rows skip `is_dead_letter_handler` and the trigger-
-  principal path** since they don't originate from a trigger. The
-  `ResolvedTrigger` synthesized for them carries a sentinel zero
-  `AdminUserId` that's never used (HTTP rows never retry under
-  sync, and async-HTTP rows don't need a principal resolution).
-- **DataPlaneState's executor field is still generic** (`Arc<E>`
-  where `E: ExecutorClient`). The dispatcher uses `Arc<dyn
-  ExecutorClient>` directly. The picloud binary clones the same
-  `Arc<LocalExecutorClient>` into both — works because the
-  concrete type implements both the trait object and the generic
-  bound.
-- **dispatcher always sets `principal: None` for HTTP rows.** As
-  noted in Open Question §3, HTTP outbox rows don't resolve a
-  principal. Sync HTTP doesn't need one (caller is anonymous);
-  async HTTP currently can't authenticate as the originating
-  caller. If that's not the intent, additive change.
-- **Cluster-mode crash recovery for claimed rows.** A claimed row
-  stays claimed indefinitely if the dispatcher crashes mid-
-  execution. v1.1.1 has one dispatcher per process so this is
-  rare; cluster mode (v1.3+) needs a stale-claim sweeper.

+
+## 3. Resolver implementation notes
+
+### 3.1 In-progress-imports stack
+
+Lives **on the per-call `PicloudModuleResolver` instance**, not on `SdkCallCx`. The resolver is constructed fresh per `Engine::execute_ast` call (see `crates/executor-core/src/engine.rs:execute_ast`), so the stack is naturally scoped to one execution. Both the stack and the depth counter are `Mutex<…>` (not `RefCell<…>`) because `rhai::ModuleResolver: SendSync` under the `sync` feature.
+
+An RAII `StackGuard` pops the stack and decrements depth on drop — a compile error or panic anywhere inside `resolve()` cleans up properly. The lock is uncontended in practice (Rhai evaluation on the engine is single-threaded).
+
+### 3.2 Sync → async bridge
+
+Rhai's `ModuleResolver::resolve` is sync; `ModuleSource::lookup` is async. The bridge:
+
+```rust
+let handle = tokio::runtime::Handle::try_current().map_err(/* surfaces as ErrorRuntime */)?;
+let lookup = tokio::task::block_in_place(|| handle.block_on(self.source.lookup(&self.cx, path)));
+```
+
+- `try_current()` (not `current()`) so test harnesses that build an `Engine` outside a Tokio runtime get a clean error instead of a panic.
+- `block_in_place` makes the call safe both on `spawn_blocking` threads (where it's a no-op) and on multi-threaded runtime worker tasks (where it instructs the runtime to relocate other tasks before we block). This was load-bearing for the resolver tests, which call `engine.execute` directly from `#[tokio::test(flavor = "multi_thread")]`.
+- A `current_thread` runtime still panics — but production callers wrap `Engine::execute` in `tokio::task::spawn_blocking` (see `LocalExecutorClient::execute_with_identity`), which avoids that path entirely.
+
+### 3.3 Cross-app isolation enforcement
+
+The resolver captures `Arc<SdkCallCx>` at construction. Every `ModuleSource::lookup` call passes `&self.cx`. The Postgres impl (`crates/manager-core/src/module_source.rs`) selects with `WHERE app_id = $1 AND kind = 'module' AND name = $2`, binding `$1` from `cx.app_id.into_inner()` — never from any script-passed argument. The Rhai script's `import "name" as alias;` syntax has no slot for an `app_id`, so there is no path by which a script in app A can name a row in app B.
+
+Verified by `resolver_cross_app_blocked` and `resolver_cross_app_module_not_found` tests.
+
+### 3.4 Module-shape validation — both layers
+
+- **Primary gate (admin endpoint)** — `manager-core::api::create_script` and `update_script` call `state.validator.validate_module(src)` whenever the effective kind is `Module`. `Engine`'s impl walks `ast.statements()`, accepting only `Stmt::Var(_, ASTFlags::CONSTANT, _)`, `Stmt::Import(..)`, and `Stmt::Noop(..)`. Anything else (top-level expression, let, if, while, …) is rejected with a clear `ValidationError::ModuleShape` message.
+- **Defense in depth (resolver)** — the resolver calls `check_module_shape` again after `engine.compile(source)`. This catches rows that bypassed the API (manual SQL inserts, future migration bugs, restoring from an older backup).
+
+Note: Rhai's default optimizer constant-folds `if true { ... }` away, so a module containing `if true { ... }` parses to an empty body and passes vacuously. This is fine semantically (the script has no observable behavior), but it surprises authors. Documented as a known acceptance edge; not worth disabling optimization for.
+
+### 3.5 What the resolver does NOT enforce
+
+- **Module access permissions** — every module in an app is importable by every other script in the same app. Per-module ACLs are explicitly v1.2+.
+- **Module versioning / pinning** — there's exactly one current version per `(app_id, name)`. v1.3+.
+
+---
+
+## 4. Cache design notes
+
+### 4.1 LRU library
+
+**`lru = "0.12"`** — added to `[workspace.dependencies]`. Standard choice, no-frills crate (`LruCache<K, V>` with `put`/`get`/`len`/etc.). Both caches use `Arc<Mutex<LruCache<K, V>>>` so they're cheap to clone and safe to share across executions.
+
+### 4.2 Cache key shapes + what's stored
+
+| Cache | Owner | Key | Value | Stores |
+|---|---|---|---|---|
+| **Script AST cache** | `LocalExecutorClient` | `ScriptId` | `CachedScript { updated_at: DateTime<Utc>, ast: Arc<rhai::AST> }` | Compiled AST for the top-level (endpoint) script. |
+| **Module cache** | `Engine` | `(AppId, String)` | `CachedModule { updated_at: DateTime<Utc>, module: Shared<rhai::Module> }` | Compiled `rhai::Module` produced by `Module::eval_ast_as_new`. |
+
+The script cache stores `Arc<AST>` so an evaluation can grab a cheap clone and hand it to `Engine::execute_ast` without holding the cache lock. The module cache stores `Shared<Module>` (= `Arc<Module>` under the `sync` feature) because that's what `ModuleResolver::resolve` must return.
+
+### 4.3 Stale-version detection
+
+Both caches use the same logic: **compare `cached.updated_at` against the freshly-known `updated_at`**.
+
+- For the script cache, the caller passes the fresh value as `ScriptIdentity.updated_at` — the orchestrator already loaded the script row to dispatch the request, so there's no extra DB hit.
+- For the module cache, the resolver must call `ModuleSource::lookup` first to learn the fresh `updated_at` — every `import` does at least one DB roundtrip. That's a deliberate trade-off (documented in CHANGELOG): the alternative (TTL caching or pub/sub) introduces staleness during edits and complicates "publish a fix immediately" UX. Worth re-evaluating in v1.3+ when LISTEN/NOTIFY makes pub/sub cheap.
+
+Mismatch → recompile + `cache.put(...)` replace. LRU eviction is automatic when capacity is exceeded.
+
+### 4.4 Capacity overrides
+
+- `PICLOUD_SCRIPT_CACHE_SIZE` (default 256, `LocalExecutorClient`)
+- `PICLOUD_MODULE_CACHE_SIZE` (default 512, `Engine`)
+
+Both clamp `max(1)` to avoid the LRU constructor's panic on zero. `Engine::with_module_cache_capacity` and `LocalExecutorClient::with_script_cache_capacity` give tests explicit handles.
+
+---
+
+## 5. Dep-graph population
+
+### 5.1 Where the extraction happens
+
+Inside the `ScriptValidator` impl on `Engine`. The trait now returns `ValidatedScript { imports: Vec<String> }`, populated by `extract_imports` (endpoint scripts) or `validate_module_source` (module scripts). Both walk `ast.statements()` and pull out `Stmt::Import(boxed_path_expr, _)` where the path is a `StringConstant`.
+
+**Dynamic imports** (`import some_var as alias;`) are NOT captured because we can't know the name at compile time. Tested by `validate_endpoint_skips_dynamic_imports_in_imports_list`. Documented as a known limitation in the CHANGELOG and migration 0016's header comment.
+
+### 5.2 Where the write happens — transactional with the script INSERT/UPDATE
+
+`PostgresScriptRepository::create` and `update` both open a `tx = pool.begin().await?`. The script row is inserted/updated inside the tx; immediately after, `replace_imports_tx(&mut tx, importer, app_id, &imports)` runs. The tx is committed at the end. If any step fails, both the script change and the dep-graph mutation roll back together. No half-state where the script row exists but the edges don't (or vice versa).
+
+`replace_imports_tx`:
+
+1. `DELETE FROM script_imports WHERE importer_script_id = $1` — replaces wholesale.
+2. `INSERT INTO script_imports ... SELECT ... FROM scripts WHERE app_id = $1 AND kind = 'module' AND name = ANY($3) ON CONFLICT DO NOTHING` — best-effort: only resolves to existing modules in the same app; unresolved names are silently skipped (no error). A later save of either script re-resolves and writes the edge.
+
+### 5.3 Schema decisions
+
+- `script_imports.app_id` is denormalized but useful: the "all imports in app X" scan happens once at boot for caching and (eventually) for the dashboard's audit view. Without it, that query would need a 3-way join.
+- `created_at` is unused by v1.1.3 logic but trivial to add now and useful for v1.2+ "first imported" diagnostics.
+- The FK on `imported_script_id` cascades — when a module is deleted, every edge referencing it goes too. The cascade isn't exercised by a unit test (it would need Postgres); it's covered by the FK design.

+
+## 7. Schema / decisions beyond the brief
+
+- **Module name shape CHECK** (`migrations/0015_scripts_kind.sql`): module names are constrained to `^[a-zA-Z_][a-zA-Z0-9_]{0,63}$`. Endpoint scripts retain the looser pre-v1.1.3 name rules so existing rows aren't invalidated. Reason: Rhai imports modules by exact string; spaces / control characters make `import "<name>"` fragile.
+- **Reserved module names**: rejected at create-time (`kv`, `docs`, `dead_letters`, `log`, `regex`, `random`, `time`, `json`, `base64`, `hex`, `url`, `http`, `files`, `pubsub`, `secrets`, `email`, `users`, `queue`). Not a security boundary — stdlib + module imports live in disjoint Rhai scopes — but a defense against author confusion.
+- **`ScriptValidator` trait return shape changed** from `Result<(), ValidationError>` to `Result<ValidatedScript, ValidationError>`. Breaking trait change, but the only impl is `Engine` in executor-core — bounded blast radius.
+- **`ExecutorClient` gains `execute_with_identity`** with a default impl that forwards to `execute`. This means `RemoteExecutorClient` keeps working without any cluster-mode awareness of the cache (the local impl handles it).
+- **Latent security fix**: trigger creation now verifies `script.app_id == app_id`. v1.1.1 and v1.1.2's trigger endpoints didn't load the target script, so an app A member could (in principle) wire a trigger that targeted a script in app B. Closed in this release; called out in the CHANGELOG.
+
+---
+
+## 8. How to verify locally (verified on HEAD `3dbead4`)
+
+After my last commit, I ran the three gates plus the dashboard check on the exact HEAD I'm handing back. **Actual** exit codes and counts (not pre-written):
+
+### 8.1 `cargo fmt --all -- --check`
+
+```
+$ cargo fmt --all -- --check
+$ echo $?
+0
+```
+
+Clean diff, **exit 0**.
+
+### 8.2 `cargo clippy --all-targets --all-features -- -D warnings`
+
+```
+$ cargo clippy --all-targets --all-features -- -D warnings
+    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.21s
+$ echo $?
+0
+```
+
+No warnings, **exit 0**.
+
+### 8.3 `cargo test --workspace`
+
+```
+$ cargo test --workspace
+... (per-suite results) ...
+$ echo $?
+0
+```
+
+Aggregate (summed across all `test result:` lines):
+
+- **PASSED = 358**
+- **FAILED = 0**
+- **IGNORED = 140** (Postgres-gated `#[ignore]` integration tests in `picloud/tests/api.rs` + 1 schema_snapshot test; need `DATABASE_URL` to run)
+- **measured = 0**
+- **filtered out = 0**
+
+### 8.4 `(cd dashboard && npm run check)`
+
+```
+$ cd dashboard && npm run check
+> picloud-dashboard@0.9.0 check
+> svelte-kit sync && svelte-check --tsconfig ./tsconfig.json
+
+1780463972778 START "/home/fabi/PiCloud/dashboard"
+1780463972779 COMPLETED 369 FILES 0 ERRORS 0 WARNINGS 0 FILES_WITH_PROBLEMS
+$ echo $?
+0
+```
+
+0 errors, 0 warnings, **exit 0**.
+
+### 8.5 Migrations apply
+
+Verified during normal `cargo test --workspace` runs — `sqlx::test` macros apply migrations 0001 through 0016 cleanly on a freshly created database for every `#[ignore]`d integration test. The from-v1.1.2 path is not exercised by these tests (each test starts from a blank DB), but the migrations are sequential and 0015/0016 only ADD COLUMN / CREATE TABLE / CREATE INDEX — no DROP, no data rewrites — so application on top of an existing 0014 state is trivially safe. The downgrade caveat is documented in the CHANGELOG.
+
+### 8.6 Manual smoke
+
+I did **not** run the full end-to-end manual smoke against a live Postgres + Caddy stack as the brief's "Done looks like" specifies. The 8 ignored `picloud/tests/api.rs` Postgres-gated tests cover the same scenarios at HTTP-API level (including the full flow: create app → module → endpoint → bind route → invoke → edit module → re-invoke → verify cache invalidation). The reviewer should run them with `--include-ignored` against a fresh DB to confirm.
+
+---
+
+## 9. Open questions for the reviewer
+
+1. **Optimizer constant-folding edge.** Module bodies containing only `if true { ... }` (or any constant-condition `if`) pass the shape validator vacuously because Rhai folds them away at parse time. A module that does nothing observable is harmless, but the inconsistency may surprise users. Options:
+   - Accept as-is (current state); document.
+   - Disable `rhai`'s optimizer in the parse-only validate path (`Engine::validate*`) so the original AST shape is preserved for the check. Adds a small cost; might leak optimizer-dependent surprises elsewhere.
+   - Add a regex/source scan as a belt-and-braces check. Fragile.
+   - **Recommend:** accept as-is; revisit if a real user hits it.
+
+2. **`ScriptKind::Module → Endpoint` transition.** Currently always allowed. The reverse (`endpoint → module`) is rejected when routes/triggers reference the script. Should `module → endpoint` also be rejected when something *imports* the module (the `script_imports` table makes this checkable now)? My read: no, because the inverse direction can't strand users — the importer just gets a runtime `ErrorModuleNotFound`-flavoured error on next invocation, and the admin can fix it by editing the source. But it's a defensible choice either way.
+
+3. **Cached-module memory pressure.** The module cache stores `Arc<rhai::Module>` per `(AppId, name)`. With many apps × many modules, this could grow. The default 512 cap with LRU eviction should handle realistic workloads, but I didn't profile heap usage with a populated cache. Recommendation: leave as-is for v1.1.3; add a metric (`picloud_module_cache_bytes`) when metrics ship in v1.1.6.
+
+4. **`rhai/internals` feature.** Enabled in executor-core to walk `ast.statements()`. The Rhai maintainers warn this surface can change without a major bump. We're pinned to the workspace `rhai = "1.19"` line (which resolved to `1.24.0` in Cargo.lock). Consider tightening to `rhai = "=1.24"` so future Cargo.lock updates are deliberate.
+
+---
+
+## 10. Deferred items (explicitly OUT of v1.1.3)
+
+Per the brief — confirming nothing crept in:
+
+- **Admin endpoints for the dep-graph** (`GET .../imports`, `GET .../imported-by`). Persisted in `script_imports`; no API surface in v1.1.3. The dashboard's "Used by" panel is a v1.2+ task.
+- **Module versioning / pinning** (`import "B@v3"`). v1.3+.
+- **Eager precompilation** at script-save time. v1.1.3 is compile-on-first-use only.
+- **Dashboard dependency-graph visualization.** v1.2+.
+- **LISTEN/NOTIFY-based cross-node invalidation.** v1.3+ (cluster mode).
+- **Module-level capabilities / ACLs.** v1.2+.
+
+---
+
+## 11. Known limitations / rough edges
+
+1. **Dynamic imports aren't dep-graph-tracked.** `import some_var as alias;` works at runtime (the resolver still loads whatever `some_var` evaluates to) but doesn't produce a `script_imports` edge. Documented in the migration 0016 header and the CHANGELOG.
+
+2. **Per-execution module cache scope.** The module cache is process-wide. Two parallel executions of different scripts in the same app importing the same module share one cache entry. That's the design — but it means a script can implicitly observe the existence of *other* in-app modules through cache timing. Not a security boundary breach (the data is same-app), but worth noting.
+
+3. **Top-level statement validation depends on `rhai/internals`.** If Rhai changes `Stmt`'s public-under-internals shape, `check_module_shape` may need a small patch. Mitigation: pin a tighter version (see §9.4).
+
+4. **No `ResolverError` carry-through.** The bridge wraps any `ModuleSourceError::Backend` as a Rhai `ErrorRuntime` string. Script-visible messages include the backend text directly (e.g. "module backend error: connection refused"). For a public-script context where principals are `None`, that could leak DB connection details on transient failures. Recommend filtering or redacting at the boundary in v1.1.4+.
+
+5. **Mid-execution module edits.** If an admin edits a module while a long-running script is mid-execution, the in-flight call keeps the old AST (atomic snapshot semantics — correct). The next call sees the new behavior. No race; just noting.
+
+6. **`StackGuard` arms unconditionally.** The RAII guard has an `armed` field but the constructor always sets it to `true` and there's no path to `false` today. Future code that wants to bypass cleanup (e.g. an early-return that shouldn't pop) can set `armed = false` before dropping the guard. Currently dead-but-cheap; I left it in for clarity.
+
+---
+
+Reviewer next steps: audit, then write `REVIEW.md`, then merge to `main` on approval. The branch is `feat/v1.1.3-modules` at `3dbead4`.

 ## Verdict
 
-**APPROVE — ready to merge to `main` as v1.1.1.**
+**APPROVE — ready to merge to `main` as v1.1.3.**
 
-The implementation is faithful to every load-bearing decision in the design notes. Static checks are green, the workspace test suite passes (243 tests pass, 132 properly-ignored DB-backed cases, 0 failures), the schema matches Layout E exactly, and the documented deviations are all defensible. There is one ambient concern about a cross-crate dependency that should be reflected in `CLAUDE.md` after the merge, but it is not a merge blocker.
+The implementation is faithful to the prompt's load-bearing requirements (cross-app isolation in the resolver, version-keyed cache invalidation, kind-aware route/trigger validation, atomic dep-graph population). Static checks reproduce green on the actual HEAD, the test suite (358 passed / 0 failed / 140 properly-ignored) comfortably exceeds the prompt's coverage target, and the §8 attestation discipline carried over cleanly from the v1.1.2 retro.
+
+Three documented deviations from the prompt — all defensible, two are net improvements. One incidental security fix to v1.1.1/v1.1.2 trigger code is exemplary defensive work. No blockers.

-## 2. Design-notes conformance (spot-checks)
+**Discipline observation (positive):** HANDBACK §8's attestation was taken on `3dbead4` (the test commit) rather than the final HEAD `3715778`. The final commit only adds `HANDBACK.md` and the dashboard-blueprint touch-ups it references in §5; nothing in that commit can change a Rust gate's outcome. I re-ran all three gates on the actual HEAD myself and they remain green. This is a non-issue — flagging it only because the v1.1.2 retro put the "verify on the exact HEAD" discipline on the table; the agent's interpretation here is defensible (HANDBACK commits can't fail Rust gates) but a strict reading would re-attest. No action needed.

-1. **Outbox column set chosen** (`script_id`, `trigger_id` polymorphic, `claimed_by TEXT`, `trigger_depth`, `root_execution_id` denormalized; no `is_dead_letter_handler` column). The design notes explicitly deferred this set to implementation. The chosen shape is sensible: dispatcher can build `ExecRequest` without re-joining; the `is_dead_letter_handler` derivation from `triggers.kind` at dispatch time is cleaner than storing redundant state. ✅
+The prompt specified "Default cap of 32." The agent chose 8 without explicitly calling it out as a deviation in HANDBACK §7 (Schema / decisions beyond the brief) — only mentioned in §1 summary and §3.1 implementation notes.
 
-2. **KV pagination is cursor-style** (base64-encoded last-key, 100 default / 1000 max). The prompt left this open; cursor-style is the right default for KV-shaped data. ✅
+**Verdict: accept the choice, note the silence.** 8 is the better default for the target audience:
+- Typical solo-dev module graphs are 2-3 deep (handlers import a utility module that maybe imports a config module).
+- 8 still leaves substantial headroom for unusual cases.
+- 8 catches accidental cycles or over-decomposition faster, which is the depth limit's actual job.
+- Env override (`PICLOUD_MODULE_IMPORT_DEPTH_MAX`) handles the rare power-user case.
 
-3. **KV TTL deferred**. Blueprint §8.1 reserved `expires_at` but v1.1.1 SDK doesn't surface TTL. Omitting the column from migration 0007 keeps the schema minimal; adding it later is a non-breaking forward migration. ✅ (CHANGELOG records the deferral.)
+The deviation itself is fine. The discipline lesson: when changing a prompt-specified default, call it out explicitly in the "decisions beyond the brief" section, even when the new value is defensible. No action needed for this release; flagging for the next retro.
 
-4. **Authz scope mapping** (4 new capabilities mapped to existing 7 scopes — `AppKvRead → script:read`, `AppKvWrite → script:write`, `AppManageTriggers → app:admin`, `AppDeadLetterManage → app:admin`). The "seven-scope commitment" is a project convention in `crates/shared/src/auth.rs:103` the prompt didn't mention; honoring it is correct. The specific mapping is defensible: a token with `script:read` on an app already implies "can see the data behind those scripts," and admin-level scope for trigger/DL management is standard for control-plane operations. ✅
+### 3.2 Module name CHECK constraint (`^[a-zA-Z_][a-zA-Z0-9_]{0,63}$`)
 
-5. **Script-as-gate authz** (`if cx.principal.is_some()` then check; else skip — public HTTP runs anonymously without an authz failure). This matches the SDK-shape doc's note that "the data plane is unauthenticated by default — public HTTP scripts run with `None`." Cross-app isolation is preserved regardless (every query keyed by `cx.app_id`). DL replay/resolve correctly bypasses this and hard-requires a principal. ✅
+Not in the prompt. Reason: Rhai's `import "<name>"` syntax takes any string; allowing spaces / control characters in module names makes import statements fragile and admits author-confusion bugs. The constraint only applies when `kind = 'module'`; endpoint scripts keep the looser pre-v1.1.3 name rules so existing rows aren't invalidated.
 
-6. **Trait split `OutboxRepo` vs `OutboxWriter`**. Orchestrator-core can't depend on manager-core; the small `OutboxWriter` trait in shared (one method) lets the orchestrator enqueue HTTP rows without inverting the dependency arrow. ✅ Pattern mirrors the existing `members_concrete`/`AuthzRepo` split.
+**Verdict: net improvement.** Explicitly noted in HANDBACK §7. Conservative defensive add.
 
-7. **`InboxResolver` in shared, `InboxRegistry` in orchestrator-core**. Same split rationale. Cluster mode (v1.3+) swaps the impl behind the unchanged trait. ✅
+### 3.3 Reserved module name list
 
-8. **manager-core now depends on executor-core**. ⚠️ **See §4 below — flagged, accepted, but should be reflected in `CLAUDE.md`.**
+Not in the prompt. The agent rejects ~18 reserved names at create-time (`kv`, `docs`, `dead_letters`, `log`, `regex`, `random`, `time`, `json`, `base64`, `hex`, `url`, `http`, `files`, `pubsub`, `secrets`, `email`, `users`, `queue`). The HANDBACK §7 correctly notes this is **not** a security boundary — Rhai stdlib + imported modules live in disjoint scopes — only an author-confusion defense.
 
-9. **Sync HTTP via outbox is the default for user routes** (admin bypass `/api/v1/execute/{id}` keeps direct dispatch). Matches the design-notes decision; the bypass's direct path is acceptable for admin tooling speed. ✅
+**Verdict: net improvement.** Cheap, defensive, easy to relax later if a user has a legitimate need.
 
-## 4. The one concern worth surfacing: manager-core → executor-core
+### 3.4 `ScriptValidator` trait return shape
 
-`CLAUDE.md` working rules say:
+The agent changed the trait from `Result<(), ValidationError>` to `Result<ValidatedScript, ValidationError>` so the validator can return the literal-path imports it extracted. The only impl is `Engine` in `executor-core`; blast radius is bounded.
 
-> Honor the three-service boundary. Don't reach across `*-core` crates. If
+**Verdict: required by the dep-graph design.** Couldn't have done v1.1.3's `script_imports` population without surfacing the imports through the validator. HANDBACK §7 calls it out explicitly. Accept.
-> orchestrator-core needs something from manager-core, define a trait in
-> shared and inject the impl.
 
-The dispatcher in manager-core directly imports `ExecRequest`, `ExecResponse`, `ExecError`, and `InvocationType` from `executor-core`:
+### 3.5 `ExecutorClient::execute_with_identity` with default impl
 
-```rust
+Not strictly a deviation — the prompt asked for AST caching but didn't prescribe the trait shape. The agent added a new method with a default impl that forwards to `execute` so `RemoteExecutorClient` keeps working. Only the local impl caches.
-// crates/manager-core/src/dispatcher.rs:27
-use picloud_executor_core::{ExecError, ExecRequest, ExecResponse, InvocationType};
-```
 
-The HANDBACK justifies this as "DTOs vs behavior — types are fine, behavior is the bright line." That's a defensible interpretation, but not what `CLAUDE.md` actually says.
+**Verdict: correct cluster-mode forward-compat.** This is the right shape — remote executors run on different processes where in-memory caching wouldn't help anyway; the local-only optimization stays local.
 
-**Two options the project can pick:**
+## 4. Substantive strengths
 
-- **(a) Accept the dependency and update `CLAUDE.md`** to clarify that the three-service boundary is about *behavior*, not *types* — `ExecRequest`/`ExecResponse`/`ExecError` are transport DTOs and crossing the wire is normal. This is the lower-friction choice and matches how the agent's instincts ran.
+**1. Cross-app isolation is genuinely airtight.** The resolver holds `Arc<SdkCallCx>` from construction; every `ModuleSource::lookup` call passes `&self.cx`; the Postgres impl scopes its `WHERE` clause to `cx.app_id`; Rhai's `import "name"` syntax has no slot for a script-passed app id. The test `cross_app_import_blocked` puts identically-named modules in two apps and asserts the resolver picks the calling app's version. There is no path I can construct for app A's script to read app B's module data.
-- **(b) Refactor**: move `ExecRequest`/`ExecResponse`/`ExecError`/`InvocationType` to `shared`. About 200 lines of moves; would land cleanly as a follow-up PR.
 
-**My recommendation: (a)**. The dispatcher genuinely needs to construct and interpret these types, and they're the natural "what the executor produces" surface — burying them in shared makes the executor's public API less self-contained. But the rule as currently written disagrees; we should pick one explicitly.
+**2. The RAII stack guard is the right shape.** [module_resolver.rs:235-299](crates/executor-core/src/module_resolver.rs#L235-L299) wraps both the stack pop and the depth decrement under one `Drop` so any early return (cycle / depth / DB error / compile error / panic inside the resolver) cleans up consistently. The lock-acquire-then-push pattern groups the read+write inside one critical section so a sibling resolve can't observe a half-pushed stack. Even though parallel `resolve()` calls on the same resolver shouldn't happen (Rhai evaluates a single AST on one thread), the explicit defensive structure is worth its small cost.
 
-This is **not a merge blocker** for v1.1.1 — the implementation already exists and works. The CLAUDE.md update can land as a small commit on `main` after the merge.
+**3. Latent security fix found and closed.** The agent discovered that v1.1.1 and v1.1.2's trigger creation endpoints didn't verify `script.app_id == app_id` — meaning an app A member could (in principle) wire a KV / docs / dead-letter trigger that targeted a script in app B. They closed it as part of v1.1.3 (since they were already touching `triggers_api.rs` for the kind=module rejection) and added the regression test `kv_trigger_rejects_cross_app_script`. The fix is correct: load the script row inside `ensure_script_targetable`, check `script.app_id == app_id` first, then check `kind != Module`. Both checks are well-tested. **This is exactly the kind of incidental security work that should be welcomed.** Worth backporting awareness to the v1.1.1/v1.1.2 retro: the fix lives on `main` going forward, but anyone running an older deploy should know.
 
-## 5. Smaller observations (no action required)
+**4. Validator-as-import-extractor sequencing.** `ScriptValidator::validate` returns a `ValidatedScript { imports }`. The script repo's `create`/`update` opens a transaction, inserts/updates the script row, then immediately calls `replace_imports_tx` with the same connection inside the same tx. Either both writes commit or both roll back. There is no half-state where the script exists but the dep-graph thinks it has no imports (or vice versa). This is the right transactional shape; HANDBACK §5.2 documents it explicitly.
 
-- **HTTP outbox rows synthesize a `ResolvedTrigger` with a sentinel zero `AdminUserId`** ([dispatcher.rs:342](crates/manager-core/src/dispatcher.rs#L342)). The HANDBACK flags this as a code smell; I agree, but the cleaner shape (`enum DispatchTarget { Trigger(ResolvedTrigger), Http(HttpRoute) }`) is a refactor that doesn't belong in v1.1.1. Worth doing in v1.1.2 alongside the docs work since the dispatcher will gain another trigger kind.
+**5. Cache invalidation model is simple and correct.** Version-keyed self-invalidation: every cache lookup compares `cached.updated_at` against the fresh `updated_at` from the source. Mismatch → recompile; match → reuse `Arc<AST>` or `Shared<Module>`. No explicit pub/sub between manager (writes) and orchestrator/resolver (reads). The price is one extra DB roundtrip per module lookup to learn the fresh `updated_at` — explicitly traded for the "publish a fix immediately" UX. The HANDBACK §4.3 notes the trade-off honestly and suggests LISTEN/NOTIFY as the v1.3+ optimization, which is the right place for it.
-- **Triggers parent `dispatch_mode` defaults to `'async'`** ([0008_triggers.sql:30](crates/manager-core/migrations/0008_triggers.sql#L30)) with `sync` allowed by the CHECK constraint but unsupported in v1.1.1 (sync trigger would mean firing inline with the originating mutation, which we don't do). The migration comment captures this; worth a future commit to either remove `'sync'` from the CHECK or use it for an `inline_pre_mutate` semantics if it ever makes sense. Not v1.1.1's problem.
-- **Metric counters are TODO** at three call sites (`picloud_trigger_depth_exceeded`, `picloud_dead_letter_handler_failures`, `picloud_abandoned_executions_total`). The events are logged via `tracing::warn`/`error` in the meantime. Per the prompt and roadmap, metrics surface is v1.1.7+. ✅
-- **Dispatcher tick cadence is 100ms with `CLAIM_BATCH = 8`**, serial per tick. The ExecutionGate bounds total concurrent executions globally, so parallelism within a tick is purely an optimization. Reasonable MVP choice; can parallelize later without changing semantics.
-- **Open Q1 in HANDBACK (claimed-rows-stuck-on-crash)** is a real cluster-mode concern, correctly out-of-scope for v1.1.1 (single dispatcher per process). Cluster mode adds a stale-claim sweeper — track for v1.3+.
-- **Open Q3 in HANDBACK (HTTP-triggered scripts run with `principal: None`)** is correct as-is. The "trigger executions inherit the registrant's principal" decision applies to triggers; HTTP routes have no registrant in that sense. Public HTTP is anonymous by design.
 
-## 6. Versioning audit
+**6. Module-shape validation runs at both admin endpoint AND resolver.** Defense in depth is the correct pattern here — the admin endpoint is the primary gate (rejects bad modules at save time with a clear error), and the resolver re-checks before compiling (catches DB-direct inserts that bypass the API surface, e.g. restoring from an old backup that didn't go through validation).
+
+## 5. Schema decisions audited
+
+| HANDBACK §7 decision | Verdict |
+|---|---|
+| Module name CHECK (`^[a-zA-Z_][a-zA-Z0-9_]{0,63}$`) only for `kind = 'module'` | ✅ Endpoint names keep looser rules; existing rows unaffected |
+| Reserved module name list | ✅ Author-confusion defense, not security |
+| `script_imports.app_id` denormalized | ✅ Avoids 3-way join for "all imports in app X"; small cost (one extra UUID per edge) |
+| `created_at` on `script_imports` | ✅ Trivial to add, useful for v1.2+ diagnostics |
+| FK cascade on `imported_script_id` | ✅ Deleting a module purges its inbound edges; correct |
+| `replace_imports_tx` uses `DELETE` + `INSERT ... ON CONFLICT DO NOTHING` | ✅ Wholesale replace; unresolved names skipped silently (re-resolves on next save of either side) |
+| Two-migration split (0015 + 0016) | ✅ Each is revertable independently if needed |
+
+## 6. Open questions (from HANDBACK §9)
+
+1. **Optimizer constant-folding** (`if true { ... }` collapsed by Rhai's optimizer, passes shape validator vacuously). HANDBACK recommends accept-as-is. **Agreed.** A module containing only constant-folded-away code has no observable behavior; the "surprise" is theoretical. The cost of disabling the optimizer (or running a regex fallback) outweighs the benefit. Document; revisit if a real user hits it.
+
+2. **`Module → Endpoint` transition** when something imports the module. HANDBACK recommends leave permissive. **Agreed.** Module→Endpoint can't strand state — importers get a runtime `ErrorModuleNotFound` and an admin edits the source to fix. The inverse (`Endpoint → Module` when routes/triggers reference) is correctly rejected because that *would* strand bound routes/triggers.
+
+3. **Cached-module memory pressure.** HANDBACK recommends leave-as-is for v1.1.3, add metric in v1.1.6 when metrics ship. **Agreed.** Default cap of 512 `Arc<Module>` per process is bounded; pathological memory growth requires many distinct (app_id, name) pairs across many apps, which doesn't match the consumer-hardware target audience.
+
+4. **`rhai/internals` feature tightening.** HANDBACK recommends `rhai = "=1.24"` exact pin. **Defer to v1.1.4.** The current pin (`rhai = "1.19"` resolving to `1.24.0` in lockfile) is the same as v1.0+. Tightening to `=1.24` is a one-line change that any contributor can make later; not v1.1.3's problem.
+
+## 7. Minor observations (no action required)
+
+- The `StackGuard::armed` field is currently always `true` with no code path that sets it to `false`. HANDBACK §11.6 calls this out honestly as "dead-but-cheap." Future opt-out paths (e.g. "we want to bypass cleanup on this branch") would need it; leaving it in for clarity is reasonable.
+- The cache `tracing::debug!` calls for hit/miss/evict are at `debug` level, not `info`, so they won't spam production logs but are available with `RUST_LOG=picloud::modules::cache=debug` for diagnostics. Sensible level choice.
+- HANDBACK §11.4 ("No `ResolverError` carry-through — backend text could leak DB connection details on transient failures") is a real concern worth pinning for v1.1.4. The current behavior surfaces "module backend error: connection refused" verbatim to scripts; in a public HTTP context where `cx.principal == None`, a script could log this and an attacker observing the response could learn internal infrastructure shape. The mitigation (filter / redact at the resolver boundary) is small and worth doing in v1.1.4.

-## 7. Manual smoke recommendation
+## 9. Recommended next steps (post-merge)
 
-The reviewer (you) does **not** need to run the manual end-to-end smoke before merging — the automated tests + the static review above cover the contracts. The smoke flow in HANDBACK §7 is worth running **after merge** as a release-validation step before tagging `v1.1.1` (if the project tags releases). Specifically:
+1. **Merge** `feat/v1.1.3-modules` into `main` (fast-forward; branch is linear ahead).
-
+2. **Pause** before dispatching v1.1.4 (Outbound HTTP & Scheduled Tasks).
-1. `docker compose up -d` (fresh DB)
+3. **For the v1.1.4 dispatch prompt**, consider including:
-2. `cargo run -p picloud`
+   - The "redact `ModuleSourceError::Backend` text at the resolver boundary" follow-up (HANDBACK §11.4) so leaking infra shape via module errors is closed.
-3. Create app + script-that-throws + KV trigger
+   - A pin-tighter `rhai = "=1.24"` lockfile note (HANDBACK §9.4 / §11.3) so internals-API drift is deliberate.
-4. Trigger a KV write → wait ~7s → confirm DL row appears
+   - The discipline lesson on **explicitly flagging prompt-default deviations** in the "decisions beyond the brief" section (re: depth-limit 8 vs 32 silence).
-5. Dashboard: red badge on apps list, list view shows the row, Replay creates a new outbox row + dispatcher re-runs, Mark resolved sets `resolution = 'ignored'`
+4. **Awareness for the v1.1.1/v1.1.2 retro**: the cross-app trigger gap that v1.1.3 closed is a real vulnerability in any v1.1.1 / v1.1.2 production deploy. The fix lives on main going forward, but anyone running an older tag should know — patch by either upgrading to v1.1.3+ or backporting the `ensure_script_targetable`'s `app_id` check.
-6. Async route test: `POST /work` with `dispatch_mode=async` route → expect 202 + JSON body
-
-If any of those misbehave post-merge, revert is straightforward (12 commits, ahead of main, no dependencies have pulled changes yet).
-
-## 8. Recommended next steps (post-merge)
-
-1. **Merge** `feat/v1.1.1-storage-and-events` into `main` (fast-forward; branch is linear ahead).
-2. **Tag** `v1.1.1` if release tagging is the project convention (git log shows v1.1.0 had a release commit but I didn't see a tag — confirm with the project owner).
-3. **Small CLAUDE.md update** clarifying the three-service boundary's scope (types crossing is fine; behavior crossing is what's prohibited). One-paragraph change.
-4. **Pause** before dispatching the v1.1.2 (Documents) agent — the v1.1.1 work shipped substantial infrastructure that v1.1.2 will lean on, and there may be small lessons from the v1.1.1 implementation to fold into the v1.1.2 prompt (e.g., reaffirming the "manager-core depends on executor-core for DTOs" pattern explicitly so the docs agent doesn't second-guess it).
 
 Branch is ready for merge. Verdict: **APPROVE**.

+//! `PicloudModuleResolver` — the v1.1.3 per-app Rhai module resolver.
+//!
+//! Replaces `DummyModuleResolver` in `Engine::build_engine`. Constructed
+//! fresh per `Engine::execute` call: holds an `Arc<SdkCallCx>` so every
+//! `import "<name>"` request resolves against the calling app
+//! (`cx.app_id`). The script-side `name` argument carries no `app_id`
+//! — that's the load-bearing cross-app isolation property.
+//!
+//! Three runtime invariants are enforced:
+//!
+//! 1. **Cross-app isolation** — `ModuleSource::lookup` is called with
+//!    `&cx`; the Postgres impl scopes by `cx.app_id` (never by a
+//!    script-passed argument).
+//! 2. **Cycle detection** — an in-progress-imports stack rejects
+//!    `A → B → A` with `ErrorInModule(... circular import detected ...)`.
+//! 3. **Depth limit** — guards against deep but acyclic chains
+//!    (default 8, override via `PICLOUD_MODULE_IMPORT_DEPTH_MAX`).
+//!
+//! Compiled modules are cached per `(app_id, name)` and invalidated by
+//! `updated_at` change — no explicit pub/sub. The cache is owned by
+//! `Engine` and shared across calls; only the resolver state (stack,
+//! depth) is per-call.

+//! `DocsServiceImpl` — wires the `DocsRepo` underneath the
+//! `picloud_shared::DocsService` trait that scripts see via the Rhai
+//! bridge.
+//!
+//! Layers added here (vs the raw repo):
+//!
+//! 1. Empty-collection rejection at the SDK boundary
+//!    (`docs/sdk-shape.md`).
+//! 2. `data` must be a JSON object for create + update. (The repo
+//!    accepts anything serde_json can serialise; the SDK contract
+//!    pins documents to map shape so dotted-path queries make sense.)
+//! 3. **Script-as-gate authz**: when `cx.principal.is_some()` we run
+//!    `authz::require(...)`; when it's `None` (public unauthenticated
+//!    HTTP — the common case for public routes) we skip the check.
+//!    Cross-app isolation isn't affected — every query is keyed by
+//!    `cx.app_id`, never an argument.
+//! 4. Query DSL parse — `find`/`find_one` parse the opaque filter
+//!    into `DocsFilter` before passing it down. Parse errors map to
+//!    `DocsError::InvalidFilter` / `UnsupportedOperator` with the
+//!    parser's message verbatim (script-visible).
+//! 5. `ServiceEvent` emission after each mutation (`create` / `update`
+//!    / `delete`). The outbox emitter (when wired) turns these into
+//!    docs-trigger fan-out via `OutboxEventEmitter::emit_docs`.
