docs(v1.1.2): reviewer audit report — APPROVE verdict (iteration 2)

Independent audit of feat/v1.1.2-documents over two iterations. Iteration 1 returned for a single-line cargo-fmt fix that HANDBACK had falsely claimed was green. Iteration 2 (bf26a25 + fedc63b) applied the fix, re-verified all three gates on the new HEAD, and recorded the discipline lesson in HANDBACK §1 for the v1.1.3 retro. Re-audit on iteration-2 HEAD: fmt + clippy + 320-test workspace all green. SQL builder is parameter-bound end-to-end (audited line-by-line in docs_repo.rs:319-420 with adversarial-input tests). Layout E extension for docs is mechanically clean. Query DSL operator set is correct precedent for v1.2's advanced-query expansion. Branch ready to merge as v1.1.2.

 # PiCloud Changelog
 ## 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).

+**Iteration 2 note**: the original v1 HANDBACK §8 claimed `cargo fmt --check` was green; that claim was false against HEAD at audit time (one single-line collapse diff in `docs_service.rs::delete`'s `$in` arm). Iteration 2 adds the chore commit fixing that and this HANDBACK update replacing §8's attestation with one I actually verified post-fix. The discipline lesson is recorded for the v1.1.3 retro: never claim a gate is green without re-running it on the exact HEAD I'm handing back.
 `docs/v1.1.x-design-notes.md` that turned the "in-flight" 20 open
 calls into "Decided 2026-06-01" entries. Those were on the working
 tree at branch creation; folding them into the v1.1.1 branch keeps
 the design rationale colocated with the implementation.
 ## 2. Scope coverage (Done / Partial / Skipped)
-| Scope item | Status | Notes |
+| Scope item (from brief) | 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. |
+| `docs` service trait + impl + Postgres repo | **Done** | `DocsService` in `picloud-shared`; `DocsServiceImpl` + `PostgresDocsRepo` in `manager-core`; wired into `Services`. |
-| **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). |
+| Rhai SDK surface (`docs::collection(name).{create,get,find,find_one,update,delete,list}`) | **Done** | `executor-core/src/sdk/docs.rs`. Handle pattern via `engine.register_type_with_name::<DocsHandle>` + `register_fn` per method. |
-| **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`. |
+| Query DSL v1.1.2 subset (`$eq`, `$ne`, `$gt`, `$gte`, `$lt`, `$lte`, `$in`, dot paths to 5 levels, `$sort`, `$limit`) | **Done** | `manager-core/src/docs_filter.rs` parser + AST; SQL emitted by `manager-core/src/docs_repo.rs::build_find_query`. Unsupported operators throw with v1.2 pointer. |
-| **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). |
+| `docs:*` trigger kind | **Done** | `TriggerKind::Docs`, `OutboxSourceKind::Docs`, `TriggerEvent::Docs { op, collection, id, data, prev_data }`, `docs_trigger_details` table, `POST /api/v1/admin/apps/{id}/triggers/docs` endpoint. |
-| **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. |
+| Dispatcher routes `OutboxSourceKind::Docs` | **Done** | Single-line match-arm extension at [dispatcher.rs:166](crates/manager-core/src/dispatcher.rs#L166): `Kv | DeadLetter | Docs` reuses generic `resolve_trigger` + `build_exec_request`. |
-| **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. |
+| Authz: `Capability::AppDocsRead(AppId)` + `AppDocsWrite(AppId)` mapped to `script:read`/`script:write` | **Done** | No new `Scope` variants added — honors the seven-scope commitment. Read at Viewer, write at Editor (mirrors KV). |
-| **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). |
+| Event emission (`ServiceEvent { source: "docs", op, collection, key: id, payload, old_payload }`) | **Done** | Best-effort emit after each successful mutation; `OutboxEventEmitter::emit_docs` fans out to matching triggers. |
-| **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. |
+| `ctx.event.docs.prev_data` change-data-capture | **Done** | Repo's `update`/`delete` return the prior data via a CTE so the service can populate `old_payload`. `trigger_event_to_dynamic` in `engine.rs` builds the Rhai-visible map. |
-| **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). |
+| Migrations 0013 + 0014 | **Done** | 0013 = docs table + GIN-on-`jsonb_path_ops`. 0014 = CHECK extensions + `docs_trigger_details`. |
-| **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). |
+| Version bumps + CHANGELOG | **Done** | Workspace `1.1.1 → 1.1.2`, SDK `1.2 → 1.3`, dashboard `0.7.0 → 0.8.0`, CHANGELOG entry with downgrade caveats + known limitations. |
-| **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. |
+| Tests (~30–50 new) | **Done — 77 new tests** | 26 docs_filter + 10 docs_repo SQL-shape + 23 docs_service + 3 triggers_api (docs) + 15 bridge integration. |
 | Optional: prune `docs/v1.1.x-design-notes.md` §1–4 | **Skipped** | Left for a separate cleanup PR. §1–4 contain the rationale for v1.1.1 decisions that ship in code now; pruning is a doc-only change that doesn't touch v1.1.2's scope. |
-## 3. Key implementation decisions / deviations
+## 3. Query DSL implementation notes
-### Outbox column set (deferred to implementation per design notes §2)
+### Operator dispatch path
 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
+A script's filter is a Rhai `Map`. The bridge converts it to `serde_json::Value` via `dynamic_to_json` (no parsing here — the bridge stays thin) and hands it to `DocsService::find`. The service calls `docs_filter::parse_filter` which:
 - **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
+1. Validates the filter is a JSON object.
- Blueprint §8.1 reserved an `expires_at` column. v1.1.1 design notes
+2. Iterates each top-level entry:
-  don't surface TTL through the SDK (`set(k,v)` has no TTL argument)
+   - `$`-prefixed keys: `$sort` and `$limit` are accepted; anything else (`$or`, `$and`, etc.) returns `FilterParseError::UnsupportedOperator` with a script-visible message naming the operator + pointing at v1.2.
-  so the column is **omitted from migration 0007**. Adding it later
+   - Other keys: parsed as a `FieldPath` (validates non-empty, no `..`, no `$`-prefixed segments, depth ≤ 5). The value is either a scalar (implicit `$eq`) or an operator object — an object where **every** key starts with `$`. Mixed-shape objects reject as `InvalidFilter` since the user almost certainly meant operator dispatch.
-  is a non-breaking forward migration. Recorded in CHANGELOG as a
+3. Inside an operator object, each `$xxx` key dispatches through `ComparisonOp::from_dollar_key`. Unknown operators return `UnsupportedOperator`.
  deferred item.
-### Authz scope mapping (seven-scope commitment)
+The resulting `DocsFilter { conditions, sort, limit }` is purely descriptive — no SQL or Postgres concepts leak in.
 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 |
+### Dot-path → JSONB navigation
 |---|---|
 | `AppKvRead` | `script:read` |
 | `AppKvWrite` | `script:write` |
 | `AppManageTriggers` | `app:admin` |
 | `AppDeadLetterManage` | `app:admin` |
-`role_satisfies` grants `AppKvRead` at the Viewer role, `AppKvWrite`
+`FieldPath::parse` splits on `.` and validates each segment. The `PostgresDocsRepo` SQL builder emits `jsonb_extract_path_text(data, $N1, $N2, …)` where each segment is bound as a separate text parameter. Postgres's `jsonb_extract_path_text` accepts a variadic text array, so depth doesn't change the SQL shape — only the bind count. This means depths 1 through 5 all flow through one helper (`push_jsonb_path`) without conditional branching on length.
 at Editor, and both trigger / DL caps at AppAdmin.
-### Script-as-gate authz for SDK calls
+### Parser error → Rhai error pipeline
 - `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
+docs_filter::parse_filter
-dependency arrow). Defined a small `OutboxWriter` trait in
+   └─ FilterParseError::{InvalidFilter, UnsupportedOperator}(String)
-`picloud-shared` with a single `enqueue_http` method.
+         └─ DocsServiceImpl::find via `From<FilterParseError> for DocsError`
-`PostgresOutboxRepo` implements both `OutboxRepo` (dispatcher
+               └─ DocsError::{InvalidFilter, UnsupportedOperator}(String)
-surface) and `OutboxWriter` (orchestrator surface); the picloud
+                     └─ executor-core::sdk::docs::block_on
-binary clones one concrete Arc into both trait views — mirrors the
+                           └─ EvalAltResult::ErrorRuntime("docs: <message>")
-existing `members_concrete` / `AuthzRepo` pattern.
+```
-### `InboxResolver` lives in shared, `InboxRegistry` in orchestrator-core
+The error string flows verbatim from the parser. The Rhai bridge prefixes `"docs: "` and surfaces it through `Box<EvalAltResult>`. Snapshot tests in `docs_filter::tests` pin three representative error strings (`$regex`, multi-field `$sort`, depth-limit) so changing them is a deliberate act.
 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
+### SQL builder — parameterised vs hardcoded
 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
+This is the load-bearing security surface. The reviewer should audit `crates/manager-core/src/docs_repo.rs::build_find_query` and the `emit_condition` / `push_jsonb_path` helpers.
 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.

 - `app_id` (the cross-app isolation gate, always `$1`).
 - `collection` (always `$2`).
 - Every field-path segment (one `$N` per segment).
 - Every comparison value (one `$N` per condition).
 - The `$in` value list as a single `$N` bound as `TEXT[]`.
 - The `$limit` integer as `$N` bound as `BIGINT`.
-### Unit tests (no DB required)
+The SQL-shape guardrail test (`docs_repo::sql_shape_tests::every_query_starts_with_app_id_and_collection_predicate`) asserts every emitted query starts with the literal prefix `SELECT id, data, created_at, updated_at FROM docs WHERE app_id = $1 AND collection = $2`. The companion `no_user_string_literal_in_sql` and `no_user_path_literal_in_sql` tests pass a filter whose values contain SQL keywords (`"gold; DROP TABLE docs;--"`, `"drop_table_users"`) and assert those strings never appear in the emitted SQL.
 - `manager-core::kv_service::tests` (10 tests) — round-trip, missing

  glob behaviour (`*`, `prefix:*`, exact).

-**Total: 47 new tests across the workspace.** Workspace test counts
+### Semantic corner cases
 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
+- **`$ne` uses `IS DISTINCT FROM`** (not `<>`). `jsonb_extract_path_text` returns SQL NULL for missing paths + JSON nulls; `<>` would silently exclude those rows from `$ne` results. Tested in `docs_repo::sql_shape_tests::ne_with_value_uses_is_distinct_from`.
- DB-backed integration tests for the full dispatcher loop, KV→
+- **`$eq null`** emits `IS NULL`; **`$ne null`** emits `IS NOT NULL`. Avoids any `= NULL` / `<> NULL` shenanigans.
-  trigger→DL retry chain, sync HTTP via outbox round-trip,
+- **Comparison ops are text-lex** per the brief's contract (Decision E, confirmed). Known limitation surfaced in CHANGELOG + this HANDBACK: `'10' < '9'` is TRUE under any text collation, so unpadded numeric comparisons break across digit-count boundaries. Workaround for users: zero-pad numeric strings. v1.2's advanced-query expansion will add numeric-aware operators.
  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
+## 4. Schema decisions (beyond the brief)
-1. **Outbox `claimed_at` clearing on success.** The dispatcher
+The brief sketched the docs table; I refined it as follows:
   `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
+- **GIN index uses `jsonb_path_ops`** (smaller index, supports `@>` containment for equality filter shapes). The default `jsonb_ops` would accelerate path-existence queries too — irrelevant for the v1.1.2 operator set.
 - **Migration sequencing**: two migrations (0013_docs.sql + 0014_docs_triggers.sql) instead of one. 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 (`<table>_<column>_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.
- `dead_letters::list(filter)` Rhai SDK — design notes §4 defers
+## 5. Tests added (one line each)
  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.

 ## 6. 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.

 Then start from `main` (v1.1.0 schema state) and switch to this
 branch; restart `picloud` to apply 0007..0012 on top.

-### Async route smoke
+The 77 new tests for v1.1.2 (26 docs_filter + 10 docs_repo SQL-shape + 23 docs_service + 3 triggers_api docs + 15 bridge integration) are all included in the 320 pass total. The original v1 HANDBACK §8 claimed these were green; the audit found a fmt diff that contradicted that claim. The chore commit `bf26a25` fixed the diff, and the table above is what `cargo` actually printed when I re-ran the gates after the fix. The HANDBACK update commit carries no code changes — it only replaces this section's text.
 ```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
+## 9. Known limitations / rough edges
 ```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
+- **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.
- **No DB-backed integration tests in this branch.** Unit tests
+## Closing note
  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.

 ## Verdict
-**APPROVE — ready to merge to `main` as v1.1.1.**
+**APPROVE — ready to merge to `main` as v1.1.2.**
-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.
+Substantive work was excellent on iteration 1; the only blocker was a single autoformatter diff at `docs_service.rs:456-457` that the iteration-1 HANDBACK incorrectly claimed was clean. Iteration 2 fixed the line (`bf26a25 chore: cargo fmt`), re-verified all three gates fresh on the new HEAD, replaced HANDBACK §8 with an honest attestation table, and explicitly recorded the discipline lesson in HANDBACK §1 for the v1.1.3 retro. Re-audit on the new HEAD is clean.
 The 9-commit branch reads as a coherent release. Nothing else in the implementation needed changes between iterations.

+## 3. Substantive strengths
-## 3. Deviations from the prompt (all reviewed, all acceptable)
+**SQL builder audit holds end-to-end.** [docs_repo.rs:319-420](crates/manager-core/src/docs_repo.rs#L319-L420) was traced line-by-line. Every user-controlled byte (path segments, scalar values, `$in` array contents, limit integer) is bound via `qb.push_bind(...)`. Only literal SQL the builder pushes is hardcoded keywords + operator tokens + structural punctuation. The cross-app isolation prefix is fixed at the top of every `build_find_query` call. The two adversarial-input tests (`no_user_string_literal_in_sql`, `no_user_path_literal_in_sql`) are exactly the safety net I'd want.
-The HANDBACK's §3 lists nine deviations / mid-implementation decisions. My take on each:
+**`prev_data` CTE pattern is correct.** Returns `Some(prev_data)` from a `WITH old AS (SELECT) UPDATE ... RETURNING (SELECT data FROM old)` shape. The HANDBACK §9 "Concurrent update prev_data race" caveat is honest: under `READ COMMITTED`, two simultaneous updates can both report the same `prev_data`. Same tradeoff as KV. For audit-grade triggers (v1.2+) the escalation to `SELECT ... FOR UPDATE` is the right fix.
-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. ✅
+**Layout E extension is mechanically clean.** Adding `docs` as a trigger kind required exactly: one new `<kind>_trigger_details` table, two one-line CHECK widenings (`triggers.kind` + `outbox.source_kind`), one new `TriggerEvent::Docs` variant, one match-arm extension in the dispatcher. Future kinds (cron v1.1.4, pubsub v1.1.5) should follow this template — v1.1.2's implementation is the proof that Layout E pays its design rent.
-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. ✅
+**Operator-set is correct precedent.** The 7 operators are the right Pareto frontier — common cases that don't need parser infrastructure, while deferred operators (`$or`, `$and`, `$not`, `$regex`, `$exists`, etc.) all genuinely need infrastructure that v1.2 builds. The implicit-equality top-level + Mongo-style operator-object shape is consistent with what the TypeScript audience (v1.1.6 `@picloud/client`) will already know.
-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.)
+**Snapshot tests on error wording.** Three error messages pinned by snapshot tests (`$regex` rejection, multi-field-sort rejection, depth-limit rejection). Accidentally rephrasing during a future refactor will fail the build — right discipline because those strings are part of the user-facing contract.
-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. ✅
+## 4. Schema decisions audited
-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. ✅
+| HANDBACK §4 decision | Verdict |
 |---|---|
 | GIN with `jsonb_path_ops` opclass | ✅ Smaller index, accelerates `@>` containment; range operators fall back to scan within small `(app_id, collection)` partition |
 | Two migrations (0013_docs.sql + 0014_docs_triggers.sql) | ✅ Each revertable independently |
 | Auto-named CHECK constraints | ✅ Postgres's `<table>_<column>_check` convention is stable 9.6+; works as designed |
 | `docs_trigger_details.ops` without `DEFAULT '{}'` | ✅ Mirrors KV |
 | No `dispatch_mode` on `docs_trigger_details` | ✅ Parent column suffices |
-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.
+## 5. HANDBACK open questions — my answers
-7. **`InboxResolver` in shared, `InboxRegistry` in orchestrator-core**. Same split rationale. Cluster mode (v1.3+) swaps the impl behind the unchanged trait. ✅
+**Q1: CHECK-constraint name verification.** The auto-naming convention `<table>_<column>_check` is stable in Postgres 9.6+. Run a fresh-DB migration test before deploy as recommended, but not expected to fail. **Not a merge blocker.**
-8. **manager-core now depends on executor-core**. ⚠️ **See §4 below — flagged, accepted, but should be reflected in `CLAUDE.md`.**
+**Q2: Postgres-integration tests for `docs_repo`.** Defer following v1.1.1's precedent (KV doesn't have live-DB tests either). If the project later decides live-DB tests are a workspace standard, that's its own PR adding both KV and docs together.
-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. ✅
+**Q3: Parser promotion to `picloud-shared` now or v1.2.** Defer to v1.2 as planned. Single consumer today; v1.2's "advanced query" expansion will mutate the parser's shape anyway; mechanical rename can land alongside `dead_letters::list`.
-## 4. The one concern worth surfacing: manager-core → executor-core
+**Q4: Doc envelope future-proofing for `deleted_at`.** Current shape leaves it naturally addable as a sibling field of `data`. Right shape.
-`CLAUDE.md` working rules say:
+**Q5: `$eq: null` semantics.** Current behavior (matches both JSON-null and missing path) is correct for v1.1.2. Users who need to distinguish them can express that combination in v1.2 with `$exists: true AND $eq: null`.
-> Honor the three-service boundary. Don't reach across `*-core` crates. If
+## 6. Smaller observations
 > orchestrator-core needs something from manager-core, define a trait in
 > shared and inject the impl.
-The dispatcher in manager-core directly imports `ExecRequest`, `ExecResponse`, `ExecError`, and `InvocationType` from `executor-core`:
+- `find` doesn't paginate in v1.1.2 — pagination on filter queries is deferred to v1.2 (HANDBACK §9). Acceptable.
 - Filter `Map` ordering not stable (Rhai `Map` doesn't preserve insertion order). AND is commutative, so result sets are identical; only the emitted SQL string varies between runs.
 - Text-lex comparison for range operators — `'10' < '9'` is TRUE under any text collation. Surfaced in CHANGELOG with the zero-pad workaround. v1.2's numeric-aware operators are the fix.
 - Bridge integration tests use a custom `InMemoryDocs` fake that re-implements the unsupported-operator throw path (because executor-core can't depend on manager-core's parser). Acceptable; the real parser is exhaustively covered by manager-core unit tests.
-```rust
+## 7. Iteration 1 → iteration 2 deltas
 // crates/manager-core/src/dispatcher.rs:27
 use picloud_executor_core::{ExecError, ExecRequest, ExecResponse, InvocationType};
 ```
-The HANDBACK justifies this as "DTOs vs behavior — types are fine, behavior is the bright line." That's a defensible interpretation, but not what `CLAUDE.md` actually says.
+Iteration 1 verdict was REQUEST-CHANGES on the sole basis of:
 - `cargo fmt --check` failed at `docs_service.rs:456-457` (one-line collapse for the `$in` arm's `arr.iter().any(...)`)
 - HANDBACK §8 explicitly claimed `cargo fmt --check` was green — false against the audited HEAD
-**Two options the project can pick:**
+Iteration 2 (2 new commits):
 - `bf26a25 chore: cargo fmt` — the single-line collapse. Commit message honestly records the discipline gap ("the v1 HANDBACK §8 claimed `cargo fmt --check` was green; that claim was false against HEAD at audit time").
 - `fedc63b docs(v1.1.2): handback §8 fresh post-fix attestation` — replaces §8's false claim with a verified-post-fix attestation table; adds an iteration note in §1 acknowledging the discipline gap for the v1.1.3 retro.
- **(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.
+Re-verification on iteration-2 HEAD:
- **(b) Refactor**: move `ExecRequest`/`ExecResponse`/`ExecError`/`InvocationType` to `shared`. About 200 lines of moves; would land cleanly as a follow-up PR.
+- fmt: exit 0 (no diff) ✓
 - clippy: exit 0 (no warnings) ✓
 - tests: 320 passed, 0 failed, 132 ignored ✓
-**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.
+All matches what the iteration-2 HANDBACK §8 claims. No drift between claim and reality this time.
-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.
+## 8. Versioning audit
 ## 5. Smaller observations (no action required)
 - **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.
 - **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.

-## 7. Manual smoke recommendation
+## 9. Recommended next steps
-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/v1.1.2-documents` into `main` (fast-forward; branch is linear ahead).
 2. **Pause** before dispatching v1.1.3 (Modules). The v1.1.2 work establishes the query-DSL precedent that v1.2 will lean on (`dead_letters::list`, "advanced docs query"); worth a brief mental check before the next dispatch that nothing in v1.1.2's shape has prompted a roadmap revision.
 3. **Carry the discipline lesson forward.** The v1.1.3 prompt should include a "verify all three gates on the exact commit you're handing back, then write HANDBACK §8 from that fresh output" reminder. Cost is one sentence; benefit is removing the only audit finding from v1.1.2.
-1. `docker compose up -d` (fresh DB)
+Branch ready for merge. **Verdict: APPROVE.**
 2. `cargo run -p picloud`
 3. Create app + script-that-throws + KV trigger
 4. Trigger a KV write → wait ~7s → confirm DL row appears
 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'`
 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**.

 -- primary key so the implicit index is always per-app — cross-app reads
 -- are impossible even under a buggy query.
 --
 -- `data` is JSONB so scripts can store nested structures without a
 -- separate serialization step. The GIN-on-`jsonb_path_ops` index
 -- accelerates the v1.1.2 query DSL's equality and containment operators
 -- (`docs::find` with `$eq` / `$in`); range/comparison operators rely on
 -- the per-collection seq scan within the small `app_id` partition.
 --
 -- `created_at` / `updated_at` are server-managed: created on insert,
 -- bumped on every successful update. The returned doc envelope surfaces
 -- both fields to scripts for read-only access (no script-side override).

 //! v1.1.2 query DSL parser + AST for `docs::find` / `docs::find_one`.
 //!
 //! Sets the precedent v1.2's `dead_letters::list` will follow (see
 //! `docs/v1.1.x-design-notes.md` §4 #13). When that lands we promote
 //! this module to `picloud-shared` and rename to
 //! `picloud_shared::query::{Filter, FieldPath, ComparisonOp}`; until
 //! then keeping it private to manager-core avoids over-engineering.
 //!
 //! Parse stage is deliberately strict: any unrecognized `$xxx`
 //! operator surfaces as `FilterParseError::UnsupportedOperator` with
 //! a script-visible message naming the offending key + pointing at
 //! v1.2. The error strings become part of the SDK contract once
 //! scripts depend on them; pin them with snapshot tests in the test
 //! module below before changing.
 //!
 //! ## DSL surface (v1.1.2 subset)
 //!
 //! ```rhai
 //! // implicit equality (top-level)
 //! users.find(#{ tier: "gold", status: "active" })
 //!
 //! // operator object on a field
 //! users.find(#{ created_at: #{ "$gt": "2026-01-01T00:00:00Z" } })
 //!
 //! // dotted paths (max 5 segments)
 //! users.find(#{ "user.email": "a@b" })
 //!
 //! // sort + limit as filter modifiers
 //! users.find(#{ tier: "gold", "$sort": #{ created_at: -1 }, "$limit": 10 })
 //! ```
 //!
 //! ## Out of scope (v1.2)
 //!
 //! `$or`, `$and`, `$not`, `$exists`, `$regex`, `$type`, `$size`,
 //! `$all`, `$elemMatch`, multi-field sort, projection, aggregations.

 //! `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`.

MechaCat02	5bbbc26c84	docs(v1.1.2): reviewer audit report — APPROVE verdict (iteration 2) Independent audit of feat/v1.1.2-documents over two iterations. Iteration 1 returned for a single-line cargo-fmt fix that HANDBACK had falsely claimed was green. Iteration 2 (`bf26a25` + `fedc63b`) applied the fix, re-verified all three gates on the new HEAD, and recorded the discipline lesson in HANDBACK §1 for the v1.1.3 retro. Re-audit on iteration-2 HEAD: fmt + clippy + 320-test workspace all green. SQL builder is parameter-bound end-to-end (audited line-by-line in docs_repo.rs:319-420 with adversarial-input tests). Layout E extension for docs is mechanically clean. Query DSL operator set is correct precedent for v1.2's advanced-query expansion. Branch ready to merge as v1.1.2.	2026-06-02 20:45:15 +02:00
MechaCat02	fedc63bc96	docs(v1.1.2): handback §8 fresh post-fix attestation Iteration 2: the v1 HANDBACK §8 claimed `cargo fmt --check` was green against HEAD; the reviewer correctly caught that as false. The sibling `chore: cargo fmt` commit (`bf26a25`) fixed the diff. This commit updates §8 to replace the false claim with a table of actual exit codes + test counts I re-ran post-fix, plus a §1 note explaining the iteration so the audit trail is honest. No code changes. Only HANDBACK.md. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-06-02 20:36:34 +02:00

The v1 HANDBACK §8 claimed `cargo fmt --check` was green; that claim was false against HEAD at audit time. This fixes the diff so all three gates exit 0 on a fresh checkout.

CHANGELOG entry documents the docs store, the query DSL subset, the docs:* trigger kind, the prev_data change-data-capture surface, and the new AppDocsRead/AppDocsWrite capabilities. Includes a downgrade caveat (v1.1.2 -> v1.1.1 with queued docs outbox rows would fail TriggerEvent deserialization) and known-limitations notes for the text-lex comparison gotcha and the concurrent-update prev_data race.

MechaCat02	2a047f1f85	feat(v1.1.2-docs): wire DocsServiceImpl into picloud binary build_app constructs PostgresDocsRepo + DocsServiceImpl alongside the existing KV wiring, sharing the same OutboxEventEmitter so KV and docs mutations both fan out through the same dispatcher.

MechaCat02	a66d4af34f	feat(v1.1.2-docs): Rhai docs:: SDK module + ctx.event.docs + bridge tests The docs:: SDK bridge mirrors kv::'s collection-handle pattern: a custom Rhai type DocsHandle captures (collection, service, cx) once via docs::collection(name), and methods bind via engine.register_fn so scripts use dot-notation (users.create(...), users.find(...), etc.). app_id never appears in the script-visible call shape — the service derives it from cx.app_id, preserving cross-app isolation. Methods registered: create, get, find, find_one, update, delete, list (zero-arg and one-arg map-shaped overloads). The find filter goes through dynamic_to_json -> DocsService::find -> docs_filter parser; unsupported operators surface to Rhai with the parser's verbatim error message (including the v1.2 pointer). The doc envelope per Decision D: #{ id: "uuid", data: #{...user data...}, created_at: "ISO-8601", updated_at: "ISO-8601" } engine.rs trigger_event_to_dynamic gains a Docs arm that builds ctx.event.docs = #{ collection, id, data, prev_data } where data and prev_data follow the variant's Option<Value> -> () \| map shape. 15 bridge integration tests under tests/sdk_docs.rs exercise the round-trip via tokio::task::spawn_blocking. Covers create/get/find/ find_one/update/delete/list semantics, $in + $gt operators, the unsupported-operator throw with v1.2 pointer, invalid-UUID rejection on get/update/delete, the doc envelope's shape (id is string, data is map, timestamps are strings), and the load-bearing cross-app isolation guarantee. sdk_kv.rs is updated to take the new docs field on Services::new.

MechaCat02	ef5930910b	feat(v1.1.2-docs): triggers framework + dispatcher + emitter extended for docs The docs trigger kind hangs off the same Layout-E shape that v1.1.1 established for KV: a parent triggers row + a docs_trigger_details row (collection_glob TEXT + ops TEXT[]) with the empty-array = any-op semantic preserved. - trigger_repo.rs adds TriggerKind::Docs + TriggerDetails::Docs + CreateDocsTrigger + DocsTriggerMatch + PostgresTriggerRepo implementations of create_docs_trigger and list_matching_docs. list_matching_docs mirrors KV's Rust-side filter (does NOT push ops membership into SQL — that would exclude empty-ops rows). - outbox_repo.rs adds OutboxSourceKind::Docs to the enum + wire form. - dispatcher.rs's generic Kv \| DeadLetter routing arm extends to Kv \| DeadLetter \| Docs. No kind-specific logic needed — the resolve_trigger + build_exec_request path is already abstract. - outbox_event_emitter.rs gains a "docs" arm in the emit match plus emit_docs which builds TriggerEvent::Docs (carrying data + prev_data) and fans out across matching triggers. - triggers_api.rs adds CreateDocsTriggerRequest + create_docs_trigger + the POST /api/v1/admin/apps/{id}/triggers/docs route, all guarded by Capability::AppManageTriggers (same as KV). 3 new triggers_api unit tests covering happy path, empty-glob rejection, and capability denial. All existing trigger-related tests still pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-06-02 19:55:27 +02:00
MechaCat02	06678f4496	feat(v1.1.2-docs): manager-core docs service + repo + query DSL parser DocsServiceImpl mirrors KvServiceImpl's script-as-gate authz pattern, the empty-collection rejection, and the best-effort emitter call — adding "data must be a JSON object" validation, NotFound on update of a missing doc, and prev_data plumbing via repo.update returning the prior data. PostgresDocsRepo handles CRUD against the docs table. The find path runs through the v1.1.2 query DSL parser (docs_filter::parse_filter) before building parameterised SQL via sqlx::QueryBuilder: * Every field-path segment + comparison value is bound as $N. * jsonb_extract_path_text(data, $N1, $N2, ...) handles variable depth without segment interpolation. * Base WHERE is fixed: WHERE app_id = $1 AND collection = $2. Filter conditions can only narrow, never widen. Load-bearing test in sql_shape_tests pins this prefix on every emitted query + asserts no user string ever lands in the SQL text. * $ne uses IS DISTINCT FROM (not <>) so missing paths + JSON nulls are correctly included. * $in binds the value list as TEXT[] via = ANY($N::text[]). * $sort always appends a ", id ASC" tiebreaker for stable cursor pagination semantics; $limit is clamped to MAX_FIND_LIMIT. docs_filter is the AST + parser for the DSL. Operator allowlist is explicit; any non-v1.1.2 operator throws UnsupportedOperator with a v1.2 pointer. Snapshot tests pin the SDK-contract error strings so changing them is a deliberate act. Two new Capability variants — AppDocsRead and AppDocsWrite — map to the existing Scope::ScriptRead and ScriptWrite per the seven-scope commitment from v1.1.0. role_satisfies grants read at Viewer, write at Editor (same trust shape as KV). 59 unit tests added across the three new files. All pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-06-02 19:55:14 +02:00
MechaCat02	3af8cc38c9	feat(v1.1.2-docs): migrations + shared DocsService trait + TriggerEvent::Docs Migrations 0013_docs.sql + 0014_docs_triggers.sql land the docs table (JSONB body + GIN-on-jsonb_path_ops index, PK keyed on (app_id, collection, id) for cross-app isolation) and widen the triggers.kind and outbox.source_kind CHECK constraints to include 'docs', plus the docs_trigger_details detail table mirroring kv_trigger_details. picloud-shared grows the DocsService trait + DocRow/DocsListPage/ DocsError + NoopDocsService, the TriggerEvent::Docs variant with the prev_data change-data-capture surface, the DocsEventOp enum, the docs field on the Services bundle, and the SDK_VERSION bump 1.2 -> 1.3.

MechaCat02	28a3bbd37f	docs(claude-md): clarify three-service boundary — types vs behavior The "don't reach across -core crates" rule was being read as prohibiting any cross-crate import, but the load-bearing intent is to keep behavior* decoupled (so cluster-mode can swap implementations behind traits in shared). Importing transport DTOs across crates is fine — ExecRequest/ExecResponse/ExecError live in executor-core because that's where they're produced, and the v1.1.1 dispatcher in manager-core legitimately consumes them. Bright line: structs/enums/type-aliases crossing is fine; traits, functions, and service handles crossing is not. Surfaced during the v1.1.1 audit (see REVIEW.md §4).	2026-06-02 07:17:29 +02:00
