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` 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` with `put`/`get`/`len`/etc.). Both caches use `Arc>>` 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, ast: Arc }` | Compiled AST for the top-level (endpoint) script. | +| **Module cache** | `Engine` | `(AppId, String)` | `CachedModule { updated_at: DateTime, module: Shared }` | Compiled `rhai::Module` produced by `Module::eval_ast_as_new`. | + +The script cache stores `Arc` 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` (= `Arc` 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 }`, 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. + +--- + +## 6. Tests added + +46 new tests across 5 crates. All green on HEAD `3dbead4`.

Separates the data-plane addition from the triggers-framework extension cleanly; either could be reverted independently if needed. -- **CHECK constraint names**: relied on Postgres's auto-name convention for inline column-CHECKs (`__check`). Migration 0014 drops `triggers_kind_check` + `outbox_source_kind_check` and re-adds the widened constraints. **The reviewer should confirm these auto-names match the inline definitions in 0008/0009** on a fresh Postgres before deploy. -- **`docs_trigger_details.ops` is `TEXT[] NOT NULL`** without a `DEFAULT '{}'` — matches `kv_trigger_details.ops`. Callers always supply a (possibly empty) array. -- **No `dispatch_mode` column on `docs_trigger_details`** — the parent `triggers.dispatch_mode` is sufficient. KV does the same. - -## 5.

Open questions for the reviewer - -1. **CHECK constraint name verification** — 0014 drops constraints named `triggers_kind_check` and `outbox_source_kind_check` (Postgres's default for inline column-CHECKs). Please verify by running migrations from scratch + a fresh `\d+ triggers` / `\d+ outbox` against a stage DB before merge. The CHANGELOG includes a downgrade caveat but the upgrade path itself depends on this name match. -2. **`docs_repo` Postgres-integration tests** — I wrote SQL-shape tests against the QueryBuilder output (pure, no DB) but did **not** add `#[ignore]`-gated Postgres tests for the CRUD path. v1.1.1 also did not add them for KV's Postgres impl; following the precedent. If the reviewer wants live-DB tests for docs as a project standard, they can land in a follow-up — happy to do them in this branch if preferred. -3. **Parser promotion to `picloud-shared`** — Decision B says promote in v1.2 when `dead_letters::list` reuses it. If the reviewer wants the rename now (`picloud_shared::query::{Filter, FieldPath, ComparisonOp}`) to avoid the future rename, that's a quick mechanical move. -4. **Doc envelope future-proofing** — Decision D ships the explicit envelope. If a soft-delete `deleted_at` field gets added in v1.2, it should land inside the envelope (not inside `data`). The trait + repo would need a new optional column; the envelope shape stays flexible for it. -5. **Whether `find` should support `null`-LHS searches** — `$eq: null` correctly returns docs where the field is JSON-null OR missing (both produce SQL NULL via `jsonb_extract_path_text`). A user may expect `$eq: null` to mean *only* JSON-null (not missing). The current behavior matches the simplest mental model but I want this confirmed. - -## 7. Deferred items beyond what the brief calls out - -- **Postgres-integration tests for `docs_repo`** — see Open Question 2. -- **Dashboard surface for docs** — no UI in v1.1.2 (the brief notes this is fine; KV doesn't have completions in `rhai-mode.ts` either). Listed as a future UX-polish task. -- **Stable cursor encoding for `find`** — the v1.1.2 `find` doesn't paginate (returns all matches up to `$limit`). The v1.2 expansion (advanced query) should add cursor pagination to `find` to match `list`'s shape. -- **Dispatcher unit test for docs routing** — I considered extending the v1.1.1 dispatcher unit-test fixture (per the plan's test list) but the dispatcher's match-arm change is a single-line `Kv | DeadLetter | Docs` extension that's already covered by the existing `Kv` and `DeadLetter` arm tests. Adding a `Docs` clone wouldn't catch anything new; flagged here so the reviewer can decide. - -## 8. How to verify locally - -```sh -# 1.

Known limitations / rough edges +Aggregate (summed across all `test result:` lines): -- **Text-lex comparison for `$gt`/`$gte`/`$lt`/`$lte`** — per the brief's contract (Decision E). Breaks across digit-count boundaries (`'10' < '9'` is TRUE under any text collation). Documented in CHANGELOG. Workaround: zero-pad numeric strings. v1.2 advanced query adds numeric-aware operators. -- **Concurrent `update()` `prev_data` race** — the CTE pattern (`WITH prev AS (SELECT) UPDATE`) mirrors KV's `set` and inherits the same last-writer-wins race under `READ COMMITTED`: two simultaneous updates can both emit the same `prev_data` if their reads race. KV accepts this; docs follows. If audit-grade `prev_data` semantics are needed later, the fix is `WITH old AS (SELECT … FOR UPDATE)`. -- **Rollback from v1.1.2 → v1.1.1** with queued `docs`-source outbox rows will cause the v1.1.1 dispatcher to fail `TriggerEvent::Docs` deserialization (`#[serde(tag = "source")]` rejects unknown variants). Drain or delete `outbox WHERE source_kind = 'docs'` before downgrading. Trunk-only deployments don't hit this. -- **`find` doesn't paginate** — v1.1.2 returns all matches in one array (subject to `$limit`). Pagination on filter queries is deferred to v1.2's advanced query expansion. -- **Filter `Map` ordering not guaranteed** — Rhai's `Map` doesn't preserve insertion order, so when a filter contains multiple top-level fields the resulting `WHERE` clause's condition order can vary between runs. Result set is identical (AND is commutative); only the SQL string differs. No correctness impact. -- **The `find` integration tests use a custom `InMemoryDocs` impl** that does its own minimal filter eval (because the executor-core crate can't depend on manager-core's parser). The fake replicates the unsupported-operator throw path so the v1.2-pointer test exercises the bridge's error-propagation pipeline end to end. +- **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** -## Closing note +### 8.4 `(cd dashboard && npm run check)` -Reviewer audits the branch; on approval, the next step is to write `REVIEW.md` mirroring v1.1.1's audit-report format.

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` 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`.
