docs(v1.1.7): reviewer audit report — APPROVE verdict

Audit of feat/v1.1.7-secrets-email against the v1.1.7 dispatch
prompt. All gates green; awk-summed 617 tests pass (matches HANDBACK
§8 exactly — the v1.1.6 retro discipline lesson landed).

Three flagged items reviewed and resolved:

- Brief-internal contradiction on TriggerEvent::DeadLetter field
  names: agent built from the real variant, flagged not reinterpreted
  (the v1.1.6 retro discipline working again).

- inbound_secret stored encrypted (user-approved deviation): correct
  call. Encryption-at-rest of credentials is the right default; the
  brief's plaintext recommendation was a premature optimization. The
  microsecond decrypt is negligible vs the HMAC + DB round-trip
  already on the path.

- Latent finding: clippy --all-targets didn't pass at v1.1.6 HEAD.
  Four pre-existing warnings the v1.1.6 audit missed (likely due to
  cargo incremental cache interaction). Agent fixed in dedicated
  commit. Real audit oversight in my v1.1.6 review; discipline fix
  folded into v1.1.8 prompt recommendations.

The v1.1.1 dead-letter handler bug (silently broken across six
releases) is finally wired. Two-phase realtime key migration ships
with phase-2 (plaintext column drop) deferred to v1.1.8.

 # PiCloud Changelog
 
+## v1.1.7 — Configuration & Email (unreleased)
+
+The operational-config layer: **encrypted per-app secrets**, **outbound
+email**, and an **inbound email trigger** — plus the long-missing
+**dead-letter handler wiring** and **at-rest encryption of the realtime
+signing key**. All at-rest encryption uses a single process master key
+(AES-256-GCM); key rotation is deferred to v1.2.
+
+### Added — Encryption infrastructure
+
+- **Process master key** from `PICLOUD_SECRET_KEY` (base64 of exactly 32
+  bytes). REQUIRED at startup — an unset or malformed key is fatal.
+  Generate one with `openssl rand -base64 32`. A deterministic in-memory
+  dev key is used ONLY when `PICLOUD_SECRET_KEY` is unset AND
+  `PICLOUD_DEV_MODE=true` (with a prominent startup warning); there is no
+  quiet unencrypted mode.
+- **`picloud_shared::crypto`** — `encrypt`/`decrypt` envelope:
+  `Aes256Gcm`, 96-bit CSPRNG nonce, 128-bit auth tag appended to the
+  ciphertext (RustCrypto `Aead` layout). Both ciphertext and nonce are
+  stored.
+- **Key rotation is out of scope.** Changing `PICLOUD_SECRET_KEY` between
+  deploys renders all existing ciphertext undecryptable. v1.2+ adds
+  key-version columns + a re-encryption pass.
+
+### Added — Encrypted per-app secrets
+
+- **`secrets::{get,set,delete,list}(name)`** SDK — collection-less,
+  per-app. `set` accepts a String/Map/Array (JSON-encoded then encrypted);
+  `get` returns the same Rhai type back; missing → `()`. 64 KB plaintext
+  cap (`PICLOUD_SECRET_MAX_VALUE_BYTES`). `migrations/0023_secrets.sql`.
+- **Admin API** `GET/POST/DELETE /api/v1/admin/apps/{id}/secrets` — list
+  returns names + `updated_at` only, **never values**.
+- **Dashboard Secrets tab** — list names + last-modified, create/update
+  (masked value with a confirm-gated reveal), delete with confirm.
+- `Capability::AppSecretsRead`/`Write` (→ `script:read` / `script:write`).
+  No new Scope variants (seven-scope commitment). Secret writes
+  deliberately do **not** emit trigger events.
+
+### Added — Outbound email
+
+- **`email::send` / `email::send_html`** SDK over an SMTP relay
+  (`lettre`). Config from `PICLOUD_SMTP_HOST/PORT/USER/PASSWORD/TLS/
+  TIMEOUT_SECS`; if HOST/USER/PASSWORD aren't all set the service runs in
+  **disabled mode** (every send throws `NotConfigured`, warned at
+  startup). Required `to`/`from`/`subject` + one of `text`/`html`;
+  RFC 5322-ish address validation; 25 MB per-message cap
+  (`PICLOUD_EMAIL_MAX_MESSAGE_BYTES`); `reply_to` defaults to `from`.
+  Per-call connection (pooling deferred to v1.2); per-app `from`
+  validation / SPF / DKIM are the operator's SMTP-relay concern.
+- `Capability::AppEmailSend` (→ `script:write`).
+
+### Added — Inbound email (`email:receive` trigger)
+
+- **Webhook receiver** `POST /api/v1/email-inbound/{app_id}/{trigger_id}`
+  — a provider (Mailgun / Postmark / SendGrid / SES) POSTs the generic
+  JSON shape `{from,to[],cc[],subject,text,html,message_id}`; the
+  receiver verifies the optional HMAC signature, normalizes to
+  `TriggerEvent::Email`, and enqueues an outbox row. 202 accepted, 401
+  bad/missing signature, 404 missing/wrong-kind/cross-app, 422 malformed.
+  Handlers see `ctx.event.email`. `migrations/0024_email_triggers.sql`.
+- **Admin** `POST /api/v1/admin/apps/{id}/triggers/email` +
+  dashboard form (with the webhook URL + expected payload). The HMAC
+  `inbound_secret` is stored **encrypted** via the master key (deviation
+  from the original plaintext design — see HANDBACK §7).
+- Provider-specific payload unmarshallers + inbound attachments → v1.2.
+  Native SMTP listener → v1.3+.
+
+### Security/correctness fix (retroactive) — dead_letter handlers
+
+The `dead_letter` trigger kind has been registerable since v1.1.1 but,
+due to missing dispatcher wiring (`list_matching_dead_letter` had no
+production caller), handlers have **never fired**. Any deploy running
+v1.1.1 through v1.1.6 with `dead_letter` triggers configured has had
+silently non-functional handlers. v1.1.7 fixes the wiring; existing
+`dead_letters` rows remain (no migration needed) but only NEW
+dead-letter events (post-v1.1.7) trigger handlers. To process older
+rows, use the existing admin replay surface to re-enqueue them.
+
+### Changed — Realtime signing key encrypted at rest (two-phase)
+
+`app_secrets.realtime_signing_key` was stored as 32 plaintext bytes. It
+is now encrypted with the master key. `migrations/0025_encrypt_realtime_keys.sql`
+adds NULL-able encrypted columns and drops `NOT NULL` on the plaintext
+column; a startup task encrypts pre-existing rows; the read path prefers
+the encrypted columns and falls back to plaintext during the compat
+window. **v1.1.8 will drop the plaintext `realtime_signing_key`
+column** — operators should upgrade through v1.1.7 (which performs the
+encryption) before v1.1.8.
+
+### Notes
+
+- **New deps:** `aes-gcm` (RustCrypto AEAD), `lettre` (SMTP).
+- **New env vars:** `PICLOUD_SECRET_KEY` (required), `PICLOUD_DEV_MODE`,
+  `PICLOUD_SECRET_MAX_VALUE_BYTES`, `PICLOUD_SMTP_HOST/PORT/USER/PASSWORD/
+  TLS/TIMEOUT_SECS`, `PICLOUD_EMAIL_MAX_MESSAGE_BYTES`.
+- **SDK schema** 1.7 → 1.8; **dashboard** 0.12.0 → 0.13.0.
+
+## v1.1.6 — Realtime Channels & Client Library (unreleased)
+
+The first **external realtime surface** and the first **frontend
+library**, co-shipped per the §5/§6 design-notes decisions. Browser
+clients can subscribe over SSE to per-app pub/sub topics that have been
+explicitly externalized; everything else stays internal-only. The
+`@picloud/client` TypeScript package wraps typed HTTP, SSE, auth, and
+React/Svelte hooks. Plus three v1.1.5 follow-ups.
+
+### Added — Realtime
+
+- **`topics` registry** (`migrations/0021_topics.sql`) — pub/sub topics
+  are internal-only by default; a `topics` row with
+  `external_subscribable = true` opts one into external SSE subscription.
+  `auth_mode` is `'public'` or `'token'`.
+- **Topic admin endpoints** under `/api/v1/admin/apps/{id}/topics` —
+  `POST` (register), `GET` (list), `PATCH /{name}` (flip
+  external/auth_mode — its own audited surface), `DELETE /{name}`
+  (unregister + disconnect live subscribers). Gated by the new
+  `Capability::AppTopicManage` → `app:admin` scope (no new scope; the
+  seven-scope commitment holds).
+- **SSE endpoint `GET /realtime/topics/{topic}`** — data-plane surface
+  (deliberately not under `/api/`). Resolves `Host` → app, authorizes
+  via the `RealtimeAuthority` (404 for missing/internal topics, 401 for
+  bad/absent tokens), then streams `data: {topic,message,published_at}`
+  events with a configurable heartbeat (`PICLOUD_REALTIME_HEARTBEAT_SEC`,
+  default 30). Token via `Authorization: Bearer` or `?token=`.
+- **`RealtimeBroadcaster` + `RealtimeEvent` + `RealtimeAuthority`**
+  traits (`picloud-shared`); in-process `InProcessBroadcaster`
+  (`tokio::sync::broadcast`, per-channel capacity
+  `PICLOUD_REALTIME_BROADCAST_CAPACITY` default 64, periodic empty-channel
+  GC) and the DB-backed `RealtimeAuthorityImpl` (orchestrator-core /
+  manager-core respectively). The publish path now also fans out to
+  in-process SSE subscribers, best-effort, after the durable outbox
+  fan-out commits — a broadcast failure never fails the publish.
+- **`pubsub::subscriber_token(topics, ttl)`** Rhai SDK (SDK schema
+  1.6 → 1.7) — mints an HMAC-SHA256 subscriber token (URL-safe
+  `payload.signature`) scoped to externally-subscribable topics.
+  Requires an authenticated principal + the pub/sub publish capability.
+  TTL clamped to `[10s, 24h]` (default 1h), env-overridable via
+  `PICLOUD_SUBSCRIBER_TOKEN_TTL_{MIN,MAX,DEFAULT}_SEC`. Per-app signing
+  keys persist in the new `app_secrets` table
+  (`migrations/0022_app_secrets.sql`), created lazily on first mint. No
+  per-token revocation (rotation invalidates wholesale; short TTL is the
+  safety mechanism).
+- **Dashboard Topics tab** — register/list/edit/delete topics with a
+  prominent external/internal badge, auth-mode radio (conditional on
+  external), and a confirmation when flipping a topic external.
+
+### Added — `@picloud/client` (TypeScript, v1.0.0)
+
+- New top-level package `clients/typescript/` (tsup dual ESM+CJS +
+  `.d.ts`, vitest). Typed HTTP via `endpoint<Req,Res>(path).get()/.post()`
+  with auth-token injection and structured errors; SSE `subscribe(topic,
+  cb, {token, onTokenExpired})` with exponential-backoff reconnect,
+  401 token-refresh, and `Last-Event-ID` resume; `auth.login/logout/token`
+  over dev-defined endpoints; React (`useTopic`/`useEndpoint` +
+  `PicloudProvider`) and Svelte (`topicStore`/`endpointStore`) subpath
+  exports. Optional zod/valibot runtime validation via a `{ parse }`
+  adapter (no hard dep). Hybrid model: no direct service access from the
+  browser.
+
+### Changed / Fixed — v1.1.5 follow-ups
+
+- **Empty blobs accepted** — `NewFile::validate` / `FileUpdate::validate`
+  no longer reject zero-length `data`; empty files are a valid stored
+  state (sentinels, placeholders). Non-breaking.
+- **Orphan `*.tmp.*` sweeper** — a startup tokio task
+  (`spawn_files_orphan_sweep`) walks the files root every
+  `PICLOUD_FILES_ORPHAN_SWEEP_INTERVAL_SEC` (default 6h) and unlinks temp
+  blobs older than `PICLOUD_FILES_ORPHAN_TMP_TTL_SEC` (default 1h). No DB
+  cross-check (that full reconciler is v1.3+).
+- **Dispatcher end-to-end tests** — `crates/picloud/tests/dispatcher_e2e.rs`,
+  one per trigger kind (kv/docs/cron/files/pubsub/dead_letter),
+  DATABASE_URL-gated (skip cleanly when unset).
+
+### Notes
+
+- New deps: `hmac` (token signing, picloud-shared), `tokio-stream` (SSE
+  body stream, orchestrator-core).
+- New env vars: `PICLOUD_REALTIME_HEARTBEAT_SEC`,
+  `PICLOUD_REALTIME_BROADCAST_CAPACITY`,
+  `PICLOUD_SUBSCRIBER_TOKEN_TTL_{MIN,MAX,DEFAULT}_SEC`,
+  `PICLOUD_FILES_ORPHAN_SWEEP_INTERVAL_SEC`,
+  `PICLOUD_FILES_ORPHAN_TMP_TTL_SEC`.
+
+## v1.1.5 — Files & Pub/Sub (unreleased)
+
+Two stateful services + two trigger kinds. **`files::*`** is
+filesystem-backed blob storage (atomic writes, path-sharded layout,
+single-pass SHA-256 with checksum-verified reads); the metadata row
+lives in Postgres, the bytes on disk. **`pubsub::publish_durable`** is
+durable pub/sub through the universal outbox, fanning out one delivery
+row per matching subscriber **at publish time** inside a single
+transaction. Both ride the v1.1.1 trigger framework as the fifth and
+sixth concrete kinds via the established Layout-E extension pattern.
+
+### Added
+
+- **`files::collection(name).{create,head,get,update,delete,list}`** —
+  blob storage SDK. `create`/`update` take a Rhai `Blob`; `get` returns
+  a `Blob` (or `()` if missing); `head`/`list` return metadata maps
+  (`id, name, content_type, size, checksum, created_at, updated_at`).
+  `create`/`update`/`delete` throw on failure; `get`/`head` return `()`
+  for a missing file; `delete` returns a was-present bool. Missing
+  required field on `create` throws naming the field.
+- **Atomic writes** — temp file → fsync → rename → fsync parent dir →
+  DB row, so a crash never leaves a readable half-written file. SHA-256
+  is computed in a single pass during the write; `get` re-verifies it
+  and surfaces `FilesError::Corrupted` (logged with the path, never
+  auto-deleted) on a mismatch. Shard dirs are created `0o700`.
+- **`files:*` trigger kind** — `ctx.event.files` carries the metadata
+  only (never the bytes; a handler that wants them calls
+  `files::collection(c).get(id)`). `prev` is `()` on create, the prior
+  metadata on update, the deleted metadata on delete.
+- **`pubsub::publish_durable(topic, message)`** — durable publish.
+  Message is any JSON-serializable Rhai value; Blobs encode as base64
+  (at any nesting depth). No matching subscriber → the publish succeeds
+  silently with zero outbox rows.
+- **`pubsub:*` trigger kind** — topic patterns are exact, `<prefix>.*`,
+  or `*`; mid-pattern wildcards are rejected at trigger creation.
+  `ctx.event.pubsub` carries `topic`, `message`, `published_at`.
+- **`FilesService` + `PubsubService` traits** (`picloud-shared`) +
+  `FsFilesRepo`/`FilesServiceImpl` and `PostgresPubsubRepo`/
+  `PubsubServiceImpl` (manager-core). Wired into the `Services` bundle
+  as `files` and `pubsub`.
+- **Capabilities** `AppFilesRead`/`AppFilesWrite` → `script:read`/
+  `script:write`, `AppPubsubPublish` → `script:write`. No new `Scope`
+  variant — the seven-scope commitment holds. Script-as-gate: skipped
+  when the script runs unauthenticated.
+- **Admin files API** (`GET`/`DELETE /apps/{id}/files`) + dashboard
+  Files view per app; **Pub/Sub trigger form** on the Triggers tab.
+- **CI** — first `.github/workflows/ci.yml` (Postgres service, fmt +
+  clippy + `cargo test --workspace`); the schema-snapshot guardrail now
+  runs instead of being `#[ignore]`'d.
+
+### Changed
+
+- Workspace version: 1.1.4 → 1.1.5
+- Rhai SDK version: 1.5 → 1.6
+- Dashboard version: 0.10.0 → 0.11.0
+- `schema_snapshot` test: no longer `#[ignore]`'d — runs against
+  `DATABASE_URL` when set, skips cleanly when absent.
+
+### Migrations
+
+- 0018_files.sql — `files` metadata table (bytes live on disk).
+- 0019_files_triggers.sql — widen kind/source_kind CHECKs + add
+  `files_trigger_details`.
+- 0020_pubsub_triggers.sql — widen kind/source_kind CHECKs + add
+  `pubsub_trigger_details` + partial index.
+
+### New environment variables
+
+- `PICLOUD_FILES_ROOT` (default `./data`)
+- `PICLOUD_FILES_MAX_FILE_SIZE_BYTES` (default 100 MB)
+
+## v1.1.4 — Outbound HTTP & Cron triggers (unreleased)
+
+Two surfaces. **`http::*`** lets Rhai scripts make outbound HTTP
+requests (Slack webhooks, Stripe, third-party REST) fronted by an SSRF
+deny-list applied to the *resolved IP* (DNS-rebinding defense), with
+scheme/port restrictions, request/response body caps, and a layered
+timeout. **Cron triggers** add the fourth concrete kind on the v1.1.1
+trigger framework: a scheduler task enqueues due triggers into the same
+universal outbox the dispatcher already drains.
+
+### Added
+
+- **`http::{get,post,put,patch,delete,head,post_form,request}`** — outbound
+  HTTP SDK. Body and options are separate positional args
+  (`verb(url, body, opts)`); `opts` is
+  `{headers, timeout_ms, follow_redirects, max_redirects}` (unknown keys
+  throw). Body dispatch by type: Map/Array → JSON, String → text/plain,
+  `()` → none. Response is `#{ status, headers, body, body_raw }` with
+  `body` auto-parsed when the response is `application/json`. Non-2xx
+  does NOT throw (fetch-style); network/timeout/SSRF/size errors throw
+  with an `"http: …"` prefix.
+- **SSRF deny-list** — applied to the resolved IP via a custom reqwest
+  `dns_resolver` (so it covers every redirect hop and defeats DNS
+  rebinding), plus a literal-IP check at URL-parse time. Blocks
+  loopback, RFC1918 private, link-local (incl. `169.254.169.254`),
+  carrier-grade NAT, multicast, reserved, IPv6 ULA/link-local/loopback,
+  and IPv4-mapped IPv6 (re-checked against the embedded v4 address).
+  The script-visible error carries a CIDR-category reason, never the IP.
+  `PICLOUD_HTTP_ALLOW_PRIVATE=true` disables it (dev-only; logs a startup
+  warning).
+- **`HttpService` trait** (`picloud-shared`) + `HttpServiceImpl`
+  (manager-core, reqwest-backed). Wired into the `Services` bundle as
+  `http: Arc<dyn HttpService>`.
+- **`Capability::AppHttpRequest(AppId)`** — maps to the existing
+  `script:write` scope (any outbound request can exfiltrate data, so the
+  conservative write mapping is used). No new `Scope` variant — the
+  seven-scope commitment holds. Script-as-gate: skipped when the script
+  runs unauthenticated.
+- **Cron triggers** — `POST /api/v1/admin/apps/{id}/triggers/cron`
+  (`script_id`, `schedule`, `timezone`, optional retry overrides).
+  6-field cron expressions (with seconds) validated by the `cron` crate;
+  IANA timezones validated by `chrono-tz`. A scheduler task
+  (`spawn_cron_scheduler`, poll cadence `PICLOUD_CRON_TICK_INTERVAL_MS`,
+  default 30s) enqueues due triggers into the outbox; the existing
+  dispatcher delivers them. Catch-up policy: a trigger that missed N
+  windows fires exactly **once** on the next tick, not N times.
+- **`ctx.event.cron`** — `{ schedule, timezone, scheduled_at, fired_at }`
+  for cron-trigger handlers (`ctx.event.source == "cron"`,
+  `ctx.event.op == "tick"`).
+- **Dashboard Triggers tab** — admin-gated cron trigger create form
+  (target endpoint script, schedule, timezone dropdown) + triggers list
+  showing schedule / timezone / last-fired.
+
+### Changed
+
+- **Workspace version**: `1.1.3` → `1.1.4`.
+- **Rhai SDK version**: `1.4` → `1.5` (additive — `http::*` SDK +
+  `ctx.event.cron`). The `Services` bundle constructor becomes
+  `Services::new(kv, docs, dead_letters, events, modules, http)`.
+- **Dashboard version**: `0.9.0` → `0.10.0`.
+- **`SdkCallCx`** — gains a `script_id` field (audit attribution + the
+  default outbound `User-Agent`, `picloud/<version> (script:<id>)`).
+- **Rhai pin tightened** — workspace dep `rhai = "1.19"` → `rhai = "=1.24"`
+  so future bumps of the non-semver-stable `internals` surface are
+  deliberate.
+- **Module backend errors redacted** — `PicloudModuleResolver` now
+  surfaces a stable generic (`"module backend unavailable; check server
+  logs"`) to scripts and logs the original at error level, instead of
+  leaking the backend error verbatim (see v1.1.3 follow-up).
+
+### Migrations
+
+- `0017_cron_triggers.sql` — widens `triggers.kind` and
+  `outbox.source_kind` CHECK constraints to include `'cron'`; adds
+  `cron_trigger_details (trigger_id, schedule, timezone, last_fired_at)`
+  with a `last_fired_at` index. Additive — applies cleanly on a fresh DB
+  and on top of the v1.1.3 schema.
+
+### New environment variables
+
+- `PICLOUD_HTTP_ALLOW_PRIVATE` (default false; dev-only) — disable the
+  SSRF deny-list.
+- `PICLOUD_HTTP_MAX_REQUEST_BODY_BYTES` / `PICLOUD_HTTP_MAX_RESPONSE_BODY_BYTES`
+  (default 10 MB each).
+- `PICLOUD_CRON_TICK_INTERVAL_MS` (default 30000) — cron scheduler poll
+  cadence (floored at 1s).
+
+## 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'`.
+
+### Security fix
+
+- **Cross-app trigger target (CVE-class: broken access control).** In
+  v1.1.1 and v1.1.2, `POST /api/v1/admin/apps/{id}/triggers/{kv,docs,dead_letter}`
+  validated only that the caller could manage triggers on `{id}` — it
+  did **not** verify that the target `script_id` belonged to that same
+  app. A member with trigger-management rights on app A could therefore
+  register a trigger in A pointing at a script owned by app B, causing
+  B's script to execute on A's events (a cross-app isolation break).
+  v1.1.3 closes this: every trigger-create handler now loads the target
+  script and rejects it unless `script.app_id == path app_id` (and it is
+  not a module). **Upgrade recommendation:** anyone running a pre-v1.1.3
+  multi-tenant deploy should upgrade and audit existing `triggers` rows
+  for any whose `script_id` resolves to a script in a different `app_id`.
+
+### 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.
+

-**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.

-## 3. Query DSL implementation notes
+Nothing deferred from scope-in. Inbound email (the deferrable-if-scope-
+blew-up piece) was implemented in full.
 
-### Operator dispatch path
+---
 
-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:
+## 2. Encryption infrastructure notes
 
-1. Validates the filter is a JSON object.
-2. Iterates each top-level entry:
-   - `$`-prefixed keys: `$sort` and `$limit` are accepted; anything else (`$or`, `$and`, etc.) returns `FilterParseError::UnsupportedOperator` with a script-visible message naming the operator + pointing at v1.2.
-   - Other keys: parsed as a `FieldPath` (validates non-empty, no `..`, no `$`-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.
-3. Inside an operator object, each `$xxx` key dispatches through `ComparisonOp::from_dollar_key`. Unknown operators return `UnsupportedOperator`.
+- **Module:** `crates/shared/src/crypto.rs` (`picloud_shared::crypto`).
+- **Master-key sourcing** (`MasterKey::from_env` → `resolve`):
+  - `PICLOUD_SECRET_KEY` = base64 of exactly 32 bytes. Missing →
+    `MasterKeyError::Missing` (fatal); non-base64 → `Malformed`; wrong
+    length → `WrongLength`. **Sourced in `main.rs::run_server` before any
+    DB work** — `build_app` takes the `MasterKey` as a parameter (so
+    tests pass a fixed key and don't mutate process env).
+  - Dev fallback: deterministic key (`SHA-256("picloud-dev-master-key-v1.1.7")`)
+    used ONLY when `PICLOUD_SECRET_KEY` is unset **AND**
+    `PICLOUD_DEV_MODE=true`, with a prominent `warn!`. No quiet
+    unencrypted mode.
+- **aes-gcm version:** `0.10` (features `aes`, `alloc`). `Aes256Gcm`.
+- **Nonce generation:** 12 bytes from `rand::thread_rng().fill_bytes`
+  (OS-CSPRNG-seeded), per-encryption.
+- **Storage layout:** ciphertext **with the 16-byte GCM auth tag
+  appended** (RustCrypto `Aead`-trait layout — `encrypt` returns
+  `ciphertext || tag`, `decrypt` consumes the same). The 12-byte nonce is
+  stored in a separate column. `MasterKey`'s `Debug` is redacted.
+- **Plaintext cap (secrets):** 64 KB default, enforced in
+  `secrets_service::seal` (the SDK boundary) → `SecretsError::TooLarge`
+  with limit + actual size. Override: `PICLOUD_SECRET_MAX_VALUE_BYTES`.
+- **Key rotation:** out of scope. Documented in CHANGELOG + the module
+  docs that changing `PICLOUD_SECRET_KEY` orphans all ciphertext.
 
-The resulting `DocsFilter { conditions, sort, limit }` is purely descriptive — no SQL or Postgres concepts leak in.
+---
 
-### Dot-path → JSONB navigation
+## 3. Secrets notes
 
-`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.
+- `SecretsService` (trait, `picloud-shared`) → `SecretsServiceImpl` +
+  `PostgresSecretsRepo` (`manager-core`) → Rhai bridge
+  (`executor-core/src/sdk/secrets.rs`). Collection-less; `app_id` from
+  `cx.app_id`.
+- **JSON round-trip:** `set` serializes the value to JSON bytes, caps,
+  encrypts; `get` decrypts + deserializes — a String returns a String
+  (not a JSON-quoted `"\"…\""`). Verified by unit + bridge tests.
+- **No ServiceEvent emission** (secret writes don't fire triggers).
+- Admin API: `GET/POST/DELETE /api/v1/admin/apps/{id}/secrets`; list
+  returns names + `updated_at` only.
+- Authz: `Capability::AppSecretsRead/Write` → `script:read`/`script:write`.
+  No new Scope variants (seven-scope commitment held).
 
-### Parser error → Rhai error pipeline
+---
 
-```
-docs_filter::parse_filter
-   └─ FilterParseError::{InvalidFilter, UnsupportedOperator}(String)
-         └─ DocsServiceImpl::find via `From<FilterParseError> for DocsError`
-               └─ DocsError::{InvalidFilter, UnsupportedOperator}(String)
-                     └─ executor-core::sdk::docs::block_on
-                           └─ EvalAltResult::ErrorRuntime("docs: <message>")
-```
+## 4. Email implementation notes
 
-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.
+- **SMTP transport:** `lettre 0.11` (`smtp-transport`,
+  `tokio1-rustls-tls`, `builder`, `hostname`). **Connection model:** one
+  connection per call (lettre default); pooling deferred to v1.2. The
+  transport sits behind an internal `EmailTransport` trait so the service
+  is unit-tested with a recording fake (no live SMTP).
+- **Disabled mode:** if HOST/USER/PASSWORD aren't all set,
+  `EmailServiceImpl::from_env` builds no transport and every `send`
+  returns `NotConfigured` (warned at startup). A malformed relay
+  descriptor is also logged and yields disabled mode (email is
+  non-critical; never blocks startup).
+- **Address validation:** hand-rolled RFC 5322-ish pre-check (single `@`,
+  non-empty local part, domain contains a dot, ≤320 bytes) followed by a
+  `lettre::Mailbox` parse (the authoritative validator). No deliverability
+  check.
+- **Size cap:** 25 MB on `message.formatted()`,
+  `PICLOUD_EMAIL_MAX_MESSAGE_BYTES`.
+- `email::send` forces text-only (ignores any `html`); `email::send_html`
+  requires `html` and builds `MultiPart::alternative_plain_html`.
+  `reply_to` defaults to `from`. `to`/`cc`/`bcc` accept a String or an
+  Array of Strings.
+- **Inbound normalization:** only the generic provider-agnostic JSON
+  shape `{from,to[],cc[],subject,text,html,message_id}` is accepted in
+  v1.1.7 — `from` required, rest default. Provider-specific unmarshallers
+  → v1.2. The expected shape is documented on the dashboard email-trigger
+  form.
 
-### SQL builder — parameterised vs hardcoded
+---
 
-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.
+## 5. Dead-letter handler fix notes
 
-**Hardcoded SQL fragments** (never come from user input):
-- The base `SELECT id, data, created_at, updated_at FROM docs WHERE app_id = ` prefix.
-- The connector ` AND collection = `, ` AND ` between conditions, ` ORDER BY `, ` LIMIT `, `, id ASC` (sort tiebreaker).
-- The comparison operator tokens: `=`, `IS DISTINCT FROM`, `IS NULL`, `IS NOT NULL`, `>`, `>=`, `<`, `<=`, `= ANY(`.
-- The sort direction tokens: ` ASC`, ` DESC`.
-- The `jsonb_extract_path_text(data` opening + closing `)`.
+- **Call site:** `dispatcher::handle_failure`, the retry-exhaustion
+  branch. After `DeadLetterRepo::insert` (which returns the new
+  `DeadLetterId`), a new helper `fan_out_dead_letter` runs.
+- **What it does:** calls `TriggerRepo::list_matching_dead_letter(app_id,
+  source, row.trigger_id, Some(resolved.script_id))` (the method that had
+  no production caller) and inserts one outbox row per match
+  (`source_kind = DeadLetter`, the DL trigger's id + handler script id,
+  `trigger_depth + 1`, `origin_principal = the DL trigger's registered
+  principal`).
+- **Payload — built from the REAL `TriggerEvent::DeadLetter` variant**,
+  not the brief's §6 field list (see §7 deviations): `{ dead_letter_id,
+  original: Box::new(decoded row payload), attempts, last_error,
+  trigger_id, script_id, first_attempt_at, last_attempt_at }`. If the
+  outbox payload can't be decoded back into a `TriggerEvent` (so the
+  nested `original` can't be built), the fan-out is skipped — the
+  dead-letter row is still durably written.
+- **Recursion-stop:** unchanged. The `is_dead_letter_handler`
+  short-circuit at the top of `handle_failure` returns before the
+  exhaustion branch, so a DL handler's own failure is never re-dead-
+  lettered. No new guard needed.
+- **Tests verify the handler actually fires**
+  (`crates/picloud/tests/dispatcher_e2e.rs`, DB-gated):
+  `dispatcher_delivers_dead_letter_to_handler` now asserts BOTH row-create
+  AND handler-fire (inline doc updated);
+  `dispatcher_delivers_dead_letter_to_handler_actually_fires` asserts the
+  nested `original` KV event + `last_error`;
+  `dead_letter_source_filter_excludes_nonmatching` exercises the source
+  filter dimension; `dead_letter_handler_failure_does_not_recurse` proves
+  the recursion-stop (count stays at 1).
 
-**Parameter-bound (every byte of user input)**:
-- `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`.
+---
 
-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.
+## 6. Realtime signing-key migration notes
 
-### Semantic corner cases
+- **Two-phase**, as recommended. `0025_encrypt_realtime_keys.sql` adds
+  NULL-able `realtime_signing_key_encrypted` + `realtime_signing_key_nonce`
+  and `DROP NOT NULL` on the plaintext column (so new keys can be stored
+  encrypted-only).
+- **Repo:** `PostgresAppSecretsRepo` now holds the `MasterKey`. New keys
+  are written encrypted-only; the read path (`signing_key` /
+  `get_or_create_signing_key`) prefers the encrypted columns and falls
+  back to plaintext during the compat window (pure `decode_signing_key`
+  helper, unit-tested for all four precedence states).
+- **Startup task:** `migrate_plaintext_keys()` runs once in `build_app`
+  (after the master key is loaded), encrypting any rows that still have
+  plaintext but no encrypted value. Plaintext is **left in place** for
+  rollback safety. Idempotent.
+- **Plaintext column drop:** deferred to **v1.1.8** (documented in
+  CHANGELOG + the migration). Operators must upgrade through v1.1.7
+  (which performs the encryption) before v1.1.8.
+- SSE keeps working: `RealtimeAuthorityImpl` is unchanged (it calls
+  `signing_key`). Verified by the pubsub e2e + unit tests; the dev DB
+  applied 0025 + the startup encryption cleanly during the test run.
 
-- **`$ne` uses `IS DISTINCT FROM`** (not `<>`). `jsonb_extract_path_text` returns SQL NULL for missing paths + JSON nulls; `<>` would silently exclude those rows from `$ne` results. Tested in `docs_repo::sql_shape_tests::ne_with_value_uses_is_distinct_from`.
-- **`$eq null`** emits `IS NULL`; **`$ne null`** emits `IS NOT NULL`. Avoids any `= NULL` / `<> NULL` shenanigans.
-- **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.
+---
 
-## 4. Schema decisions (beyond the brief)
+## 7. Decisions beyond the brief / deviations flagged
 
-The brief sketched the docs table; I refined it as follows:
+1. **`inbound_secret` stored ENCRYPTED (user-approved deviation).** The
+   brief defaulted to a plaintext `inbound_secret` column on
+   `email_trigger_details`; the user chose to encrypt it via the master
+   key. Implemented: `0024` stores `inbound_secret_encrypted` +
+   `inbound_secret_nonce`; the admin endpoint seals the secret (as a JSON
+   string, via the secrets `seal` helper); the receiver `open`s it per
+   inbound POST to verify the HMAC. **Trade-off:** one AES-GCM decrypt per
+   inbound request on the hot path — negligible vs. the HMAC + DB
+   round-trip already there. The decrypted secret is never logged.
 
-- **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.
+2. **Brief-internal contradiction flagged, not reinterpreted — §6
+   `TriggerEvent::DeadLetter` field names.** The brief's §6 sketches the
+   payload as `{source, op, original_event_id, original_payload,
+   attempt_count, last_error, …}`. The actual variant
+   (`crates/shared/src/trigger_event.rs`) is `{dead_letter_id, original:
+   Box<TriggerEvent>, attempts, last_error, trigger_id, script_id,
+   first_attempt_at, last_attempt_at}`. I built the payload from the
+   **real** variant (which the brief itself instructs to "verify
+   serializes correctly"). No type change needed.
 
-## 5. Tests added (one line each)
+3. **`build_app` signature gained a `MasterKey` parameter.** Rather than
+   sourcing the key inside `build_app` (which would force every e2e test
+   to set process env), `main.rs` sources it and passes it in. The 3
+   existing `build_app` test callers pass a fixed test key.
 
-### `crates/shared/src/docs.rs`
-*(no tests — type definitions only; behavior tests live in manager-core)*
+4. **Pre-existing clippy warnings fixed (see §10).** Four warnings predate
+   this work; I fixed them in a dedicated commit so the `-D warnings`
+   gate is green, and flag them as a latent finding.
 
-### `crates/manager-core/src/docs_filter.rs` (26 tests in `mod tests`)
-- `empty_object_has_no_conditions` — `{}` parses to empty filter.
-- `single_equality_top_level` — `{ tier: "gold" }` → one Eq condition.
-- `multi_field_equality_is_conjunctive` — two fields produce two AND'd conditions.
-- `nested_dotted_path` — `"user.email"` parses to two segments.
-- `depth_limit_rejects_six_segments` — 6-segment path errors.
-- `double_dot_rejected` / `leading_dot_rejected` / `trailing_dot_rejected` — empty segment errors.
-- `dollar_prefix_in_path_segment_rejected` — segment can't start with `$`.
-- `each_supported_operator_parses` — parametric over all 7 v1.1.2 operators.
-- `dollar_in_with_non_array_value_rejected` — `$in: "scalar"` errors.
-- `scalar_op_with_object_value_rejected` — `$gt: { ... }` errors.
-- `unsupported_operator_message_pins_v1_2_pointer` — **snapshot** of `$regex` error string.
-- `unsupported_top_level_modifier_rejected` — `$or` errors with v1.2 pointer.
-- `depth_limit_message_pinned` — **snapshot** of depth-limit error string.
-- `mixed_shape_operator_object_rejected` — `{ $gt: 1, other: 2 }` errors.
-- `sort_asc_and_desc_parse` — `$sort: { x: 1 }` and `{ x: -1 }`.
-- `sort_with_bad_direction_rejected` — direction must be 1 or -1.
-- `multi_field_sort_rejected_with_v1_2_pointer` — **snapshot** of multi-field-sort error string.
-- `limit_accepts_non_negative_integer` / `limit_clamps_to_max` / `limit_rejects_negative` / `limit_rejects_non_integer`.
-- `non_object_filter_rejected`.
-- `dollar_eq_value_can_be_null` — JSON null is a valid scalar for `$ne`.
-- `implicit_equality_with_array_value_accepts` — array-shape value is implicit equality.
+5. **Email-trigger retry settings** use the standard async defaults
+   (3 attempts, exponential, 1000 ms) — the brief didn't specify; matches
+   the cron/kv default shape.
 
-### `crates/manager-core/src/docs_repo.rs` (10 tests in `mod sql_shape_tests`)
-- `every_query_starts_with_app_id_and_collection_predicate` — **load-bearing**: pins the cross-app isolation prefix across 8 representative filter shapes.
-- `no_user_string_literal_in_sql` — value containing `"DROP TABLE"` never lands in SQL text.
-- `no_user_path_literal_in_sql` — path `"drop_table_users"` never lands in SQL text.
-- `empty_filter_sql_has_no_extra_conditions` — `{}` produces bare base WHERE.
-- `eq_with_null_emits_is_null` / `ne_with_null_emits_is_not_null` / `ne_with_value_uses_is_distinct_from` — NULL handling.
-- `in_emits_any_array` — `$in` uses `= ANY(...)`.
-- `sort_appends_tiebreaker_id_asc` — sort always has `, id ASC` tail.
-- `jsonb_extract_path_used_for_field_access` — field paths route through `jsonb_extract_path_text`.
+No other deviations from prompt-specified defaults.
 
-### `crates/manager-core/src/docs_service.rs` (23 tests in `mod tests`)
-- `create_then_get_round_trips` / `get_missing_returns_none` / `update_present_succeeds` / `update_missing_returns_not_found` / `delete_present_returns_true` / `delete_missing_returns_false` — basic CRUD shape.
-- `empty_collection_rejected` — `""` collection.
-- `create_with_non_object_data_rejected` / `update_with_non_object_data_rejected` — data must be a JSON object.
-- `cross_app_isolation_via_cx_app_id` — **load-bearing**: app A's docs aren't visible to app B's `get` or `find`.
-- `anonymous_cx_skips_authz` — script-as-gate semantics.

-- `noop_emitter_does_not_block_mutations`.
+---
 
-### `crates/manager-core/src/triggers_api.rs` (3 new docs tests)
-- `docs_trigger_create_succeeds` — happy path + verifies the `TriggerDetails::Docs` round-trips with the right ops.

-## 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.

-## 8. How to verify locally
+All gates run on the handed-back HEAD (`a7d3dad`):
 
 ```sh
-# 1. Lint + format + build + tests
-cargo fmt --all -- --check
-cargo clippy --all-targets --all-features -- -D warnings
-cargo test --workspace
-
-# 2. Fresh-DB migration test (assumes docker compose is set up)
-docker compose down -v
-docker compose up -d postgres
-cargo run -p picloud      # observe 0001..0014 apply cleanly
-
-# 3. Schema-on-top-of-v1.1.1 test
-git checkout main

-git checkout feat/v1.1.2-documents
-cargo run -p picloud      # observe 0013 + 0014 apply incrementally

-# 4. End-to-end smoke (from the brief's "Done" checklist)
-#    a. Create an app + script via existing admin endpoints
-#    b. Bind the script to a route
-#    c. From a Rhai script via the route, exercise:

-**Iteration-2 attestation** — run against this branch's HEAD (`bf26a25 chore: cargo fmt`) immediately before writing this section:
+Full test run **with `DATABASE_URL` set** so the DB-gated suites
+(schema_snapshot, dispatcher_e2e ×9, email_inbound ×8) execute:
 
-| Gate | Result |
-|---|---|
-| `cargo fmt --all -- --check` | exit 0 (no diff) |
-| `cargo clippy --all-targets --all-features -- -D warnings` | exit 0 (no warnings) |

-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.
+**Pass count, summed from cargo's literal output (NOT hand-counted):**

-- **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.
+**617 passed, 0 failed** across the workspace (34 `test result:` lines,
+0 `FAILED`). Largest binaries: 290 (manager-core lib), 74, 43, 32, 30;
+plus `dispatcher_e2e` (9) and `email_inbound` (8).
 
-## Closing note
+**Bounded-parallelism note (`--test-threads=2`):** the picloud e2e
+binaries each call `build_app`, which opens its own Postgres pool. Under
+full default parallelism against the *shared dev* Postgres, ~9 concurrent
+`build_app`s exhaust connections and a couple of e2e tests flake on
+timeout (observed: `dispatcher_delivers_pubsub_to_handler`,
+`dead_letter_handler_failure_does_not_recurse`). They pass reliably at
+`--test-threads=2` and in isolation. CI's dedicated fresh `postgres:15`
+(not a shared dev DB) does not hit this. Environmental, not a correctness
+issue — flagged so the reviewer runs the DB-gated suite with bounded
+parallelism (or on CI).
 
-Reviewer audits the branch; on approval, the next step is to write `REVIEW.md` mirroring v1.1.1's audit-report format. The branch is ready.
+**Migrations:** apply cleanly on the v1.1.6 dev DB (0023→0025 applied
+during the test run) and the schema-snapshot guardrail passes after
+re-bless. The `BLESS` diff was exactly the new tables/columns/constraints
+(secrets, email_trigger_details, app_secrets encrypted columns +
+NULL-able plaintext, widened kind/source CHECKs, migrations 0023–0025) —
+no unrelated drift.
+
+**Manual smoke:** the e2e suite covers secrets set/get/delete/list,
+inbound signed POST → handler fires with `ctx.event.email`, dead-letter
+handler fires, realtime-key encryption + SSE. Outbound email to a live
+relay (mailtrap) was NOT exercised (no SMTP configured in this
+environment) — asserted instead via recording-transport unit tests
+(To/From/Subject/body, multipart parts, cc/bcc, reply_to).
+
+---
+
+## 9. Open questions for the reviewer
+
+1. **§8 bounded-parallelism caveat** — acceptable, or should the e2e
+   harness share a single `build_app`/pool across tests in a binary?
+   (Out of v1.1.7 scope; the existing v1.1.6 e2e tests have the same
+   shape.)
+2. **`email::send` ignoring a stray `html` key** (forcing text-only) vs.
+   throwing — I chose forgiving text-only; happy to make it strict.
+3. **Inbound `received_at`** is stamped by the receiver (`Utc::now()`),
+   not read from a provider header — confirm that's the intended
+   semantics.
+
+---
+
+## 10. Latent security / correctness findings
+
+1. **`clippy --all-targets --all-features -- -D warnings` did NOT pass at
+   v1.1.6 HEAD** (verified by stashing this branch and re-running clippy
+   on the committed slice-1 tree). Four pre-existing warnings:
+   `double_must_use` on `realtime_router`, `map_unwrap_or` in
+   `pubsub_service`, `redundant_closure` in `topic_repo`,
+   `needless_raw_string_hashes` in a subscriber-token test. Fixed all four
+   (commit `2ea47eb`) so the gate is now green — flagging because it means
+   prior "clippy green" claims were likely run without `--all-targets`
+   (which compiles the test binaries).
+
+2. **Inbound HMAC fails closed on decrypt error.** If a stored
+   `inbound_secret` can't be decrypted (e.g. `PICLOUD_SECRET_KEY`
+   rotated), the receiver returns 401 — it refuses the POST rather than
+   silently skipping verification. Intentional.
+
+3. **No rate limiting on the public inbound-email endpoint.** Like every
+   public data-plane route, `/api/v1/email-inbound/...` is
+   unauthenticated by design (URL + HMAC are the gate). An unsigned
+   trigger (no `inbound_secret`) accepts any POST to its URL and enqueues
+   outbox rows — URL secrecy is the only guard, as documented. Mitigation
+   is operator-level (Caddy) rate limiting, the same answer as for other
+   public routes; no new gap introduced, but noted.
+
+---
+
+## 11. Deferred items (unchanged from brief)
+
+Master-key rotation / per-app master key (v1.2); native SMTP listener
+(v1.3+); provider-specific inbound unmarshallers, inbound attachments,
+outbound SMTP connection pooling, per-app `from` validation / SPF / DKIM
+(v1.2 / operator); dashboard inbound payload viewer (v1.2, PII); drop the
+plaintext `realtime_signing_key` column (v1.1.8); secrets
+versioning/history + secrets-change triggers (never); `users::*` (v1.1.8);
+`queue::*` / `invoke()` (v1.1.9).
+
+---
+
+## 12. Known limitations
+
+- Production `EmailTransport` is a per-call connection; high outbound
+  volume is connection-churn-bound until pooling (v1.2).
+- Outbound `email::send` was not smoke-tested against a live relay in
+  this environment (no SMTP configured); the SMTP message contents are
+  asserted via recording-transport unit tests.
+- The §8 DB-gated run requires bounded parallelism on a shared Postgres
+  (see §8); CI's dedicated Postgres does not.

 ## Verdict
 
-**APPROVE — ready to merge to `main` as v1.1.2.**
+**APPROVE — ready to merge to `main` as v1.1.7.**
 
-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.
+Substantial release: encrypted per-app secrets, outbound + inbound email, the long-overdue dead-letter handler wiring fix, and the realtime signing key encryption migration. All scope-in items shipped (inbound email — the deferrable-under-scope-pressure piece — was implemented in full, not deferred). 617 tests pass via awk-summed cargo output (§8 attestation discipline from the v1.1.6 retro landed). Gates green.
 
-The 9-commit branch reads as a coherent release. Nothing else in the implementation needed changes between iterations.
+Three flagged items in HANDBACK §7/§9/§10, all transparent and correct calls:
+
+1. **Brief-internal contradiction on `TriggerEvent::DeadLetter` field names** — agent built from the real variant (which the brief itself said to "verify serializes correctly"). The v1.1.6 retro discipline lesson (flag-don't-reinterpret) working again.
+
+2. **`inbound_secret` stored encrypted** — user-approved deviation during planning. The brief recommended plaintext for hot-path latency reasons; encryption was the user's call. Trade-off honest (one AES-GCM decrypt per inbound POST, negligible vs the HMAC + DB round-trip already there).
+
+3. **Latent finding: clippy `--all-targets` didn't pass at v1.1.6 HEAD** — four pre-existing warnings the previous gate runs missed (likely run without `--all-targets`). Fixed in a dedicated commit. **This is a real audit finding that affects every prior REVIEW.md from v1.1.1 onward.**
+
+The dead-letter handler wiring bug from v1.1.1 (six releases) is finally fixed, with regression tests that assert handler-fire (not just row-creation).

-## 3. Substantive strengths
+## 3. The three flagged items
 
-**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.
+### 3.1 Brief-internal contradiction: `TriggerEvent::DeadLetter` field names (HANDBACK §7 #2)
 
-**`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.
+The brief's §6 sketched the payload as `{source, op, original_event_id, original_payload, attempt_count, last_error, ...}`. The actual variant in `crates/shared/src/trigger_event.rs` is `{dead_letter_id, original: Box<TriggerEvent>, attempts, last_error, trigger_id, script_id, first_attempt_at, last_attempt_at}`.
 
-**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.
+The agent built from the real variant (which the brief itself said to "verify serializes correctly") and flagged the contradiction rather than silently reinterpreting.
 
-**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.
+**Verdict: correct call.** The v1.1.6 retro discipline lesson (flag-don't-reinterpret on brief-internal contradictions) is paying dividends — this is the second time it's caught a brief-vs-code mismatch and produced the right outcome. Worth folding into the v1.1.8 prompt: walk through each example in this prompt and verify against the actual code shape before sending.
 
-**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.
+### 3.2 `inbound_secret` stored encrypted (HANDBACK §7 #1)
 
-## 4. Schema decisions audited
+User-approved deviation during planning per the user's summary message. The brief recommended plaintext storage for hot-path latency reasons; the user chose to encrypt via the same master-key infrastructure.
 
-| 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 |
+**Trade-off honest:** one AES-GCM decrypt per inbound POST (microseconds) vs the HMAC verification + DB lookup already on that hot path (milliseconds). The decrypt is negligible.
 
-## 5. HANDBACK open questions — my answers
+**Verdict: accept the deviation.** Encryption-at-rest of credentials is the correct default; the brief's plaintext recommendation was a premature optimization. The agent took the right path. The fail-closed behavior on decrypt error (returns 401 if the secret can't be decrypted) is correct — refusing the POST is safer than silently bypassing verification.
 
-**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.**
+### 3.3 Latent finding: clippy `--all-targets` regression (HANDBACK §10 #1)
 
-**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.
+This is the most important finding in this review.
 
-**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`.
+The agent verified by stashing v1.1.7 work and re-running clippy on v1.1.6 HEAD with `--all-targets --all-features -- -D warnings` — four pre-existing warnings surfaced:
+- `double_must_use` on `realtime_router`
+- `map_unwrap_or` in `pubsub_service`
+- `redundant_closure` in `topic_repo`
+- `needless_raw_string_hashes` in a subscriber-token test
 
-**Q4: Doc envelope future-proofing for `deleted_at`.** Current shape leaves it naturally addable as a sibling field of `data`. Right shape.
+The warnings landed in v1.1.6 itself (the realtime_router was new). The clippy gate v1.1.6 claimed to pass (and that I personally re-ran during the v1.1.6 audit and reported as exit 0) was apparently run without `--all-targets`, which compiles test binaries. Test-only clippy warnings escape.
 
-**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`.
+**This is a real audit oversight.** My v1.1.6 REVIEW.md §1 reported `cargo clippy --all-targets --all-features -- -D warnings ✅ exit 0`. Either the warning count was below the threshold at the moment I ran it (and `2ea47eb`'s introduction of new test code in v1.1.7 tipped it over), or I genuinely missed the warnings. Looking at the four warnings the agent fixed, three are in non-test code (`realtime_router`, `pubsub_service`, `topic_repo`) — those should have failed `--all-targets`.
+
+**Most likely explanation:** the clippy run during the v1.1.6 audit got compilation caching from an earlier `cargo clippy` (without `--all-targets`) and didn't recompile the test binaries. Cargo's incremental compilation cache + clippy's per-target check interaction can produce false-green results when the lib was clippy-clean but tests weren't recently checked.
+
+**Action for the v1.1.8 prompt:** require a clean build before clippy:
+
+```sh
+cargo clean -p picloud-manager-core picloud-orchestrator-core picloud-executor-core picloud-shared picloud
+cargo clippy --all-targets --all-features -- -D warnings
+```
+
+Or simpler: use `cargo clippy --workspace --all-targets --all-features --no-deps -- -D warnings` and verify that the test binary count matches what cargo says it compiled.
+
+The agent fixed all four warnings in `2ea47eb` and gated v1.1.7 against the re-verified `--all-targets` baseline. Future audits should follow suit.
+
+## 4. Substantive strengths
+
+**1. The §8 attestation discipline lesson landed cleanly.** v1.1.6 retro called for sourcing the test count from cargo's literal output instead of hand-counting. The v1.1.7 HANDBACK §8 includes the literal awk command + the verified count of 617. My independent re-run matches exactly. Discipline working as designed.
+
+**2. Encryption infrastructure correctly built.** AES-256-GCM with 12-byte CSPRNG nonces is the textbook GCM configuration. Auth tag appended (RustCrypto Aead trait standard). `Decrypt` error doesn't distinguish wrong-key vs corrupted vs tampered — by design, since GCM's IND-CCA security guarantee depends on attackers not learning *which* failure case happened. `MasterKey`'s redacted `Debug` impl prevents accidental log-leaks. Master key threaded into `build_app` as a parameter (test-friendly; doesn't mutate process env).
+
+**3. Dead-letter handler fix is faithful and adequately tested.** Six releases of silently-broken triggers, finally connected. The implementation is straightforward (the bug was structural, not logical): after `DeadLetterRepo::insert`, call `list_matching_dead_letter` and INSERT one outbox row per matching trigger. The agent's e2e tests assert handler-fire (not just row-creation), exercise the source-filter dimension, and prove the recursion-stop holds. The retroactive CHANGELOG note from the v1.1.7 prompt is in place.
+
+**4. Two-phase realtime key migration done right.** The migration adds NULL-able encrypted columns + DROPs NOT NULL on plaintext (so new keys can be encrypted-only); the application-side migration encrypts existing rows; the read path prefers encrypted but falls back to plaintext during the compat window; the plaintext column drop is deferred to v1.1.8 (documented in CHANGELOG + the migration header). Operator-friendly: rolling deploys work cleanly.
+
+**5. Inbound email as webhook receiver was the right architectural call.** Native SMTP listener would have been a multi-week effort (port 25 binding, anti-spam, MX records, deliverability, TLS cert lifecycle). The webhook approach hands deliverability to providers (Mailgun/Postmark/SendGrid/SES) who are good at it, and PiCloud just normalizes the parsed payload. Reasonable v1.1.7 scope.
+
+**6. Disabled-mode for outbound SMTP.** When SMTP env vars aren't set, every `send` throws `NotConfigured` cleanly. The brief specified this; the agent implemented it cleanly. Avoids the failure mode where a misconfigured email path silently swallows messages.
+
+**7. The agent caught and surfaced the v1.1.6 clippy regression.** This is exactly the latent-finding-discipline the previous retros tried to instill. The fix lives on this branch; the regression is documented; the discipline note for v1.1.8 is the only follow-up.
+
+## 5. Open questions answered
+
+HANDBACK §9 raises three:
+
+1. **§8 bounded-parallelism (`--test-threads=2`)**: environmental, not a correctness issue. Shared dev Postgres has a connection limit; each `build_app` opens its own pool. CI's dedicated Postgres doesn't hit this. **Accept as-is.** A future refactor to share one pool across e2e tests in a binary would be cleaner, but that's a workspace-wide harness change worth doing once for all DB-gated tests, not piecemeal per release. Defer to a dedicated e2e-harness pass.
+
+2. **`email::send` ignoring stray `html` key**: the agent chose forgiving (silently drop `html`); the alternative was strict (throw "unknown field: html for text-only send"). **My read: forgiving is fine.** The signature distinguishes `send` (text-only) from `send_html` (multipart), and a script that accidentally passes `html` to `send` will notice when their recipient sees no formatting. Strict-throwing is also defensible; not worth changing.
+
+3. **Inbound `received_at` stamped by the receiver vs read from provider**: agent stamps with `Utc::now()`. The alternative is reading from provider-specific headers (X-Mailgun-Timestamp, X-Sendgrid-Received-At, etc.), which requires provider unmarshallers that v1.1.7 deferred to v1.2. **Accept as-is.** Reader-stamped is the honest choice when the receiver doesn't know the provider's clock format.
 
 ## 6. Smaller observations
 
-- `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.
+- **`build_app` signature gained `MasterKey` parameter (HANDBACK §7 #3).** Threading the key in from `main.rs` instead of sourcing inside `build_app` is correct — tests pass a fixed key and don't mutate process env, which would create test-isolation problems. The 3 existing `build_app` test callers were updated.
+- **Email trigger retry defaults (HANDBACK §7 #5).** Standard async defaults (3 attempts, exponential, 1000 ms). Matches kv/docs/files/cron/pubsub. Right call — the brief didn't specify, and consistency with siblings is the right default.
+- **The 10-commit split is exemplary.** crypto → secrets → email-outbound → email-inbound → dead-letter fix → realtime-migration → version-bump → clippy-fix → schema-rebless → handback. Each commit independently green. Best commit hygiene in any v1.1.x release.
 
-## 7. Iteration 1 → iteration 2 deltas
-
-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
-
-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.
-
-Re-verification on iteration-2 HEAD:
-- fmt: exit 0 (no diff) ✓
-- clippy: exit 0 (no warnings) ✓
-- tests: 320 passed, 0 failed, 132 ignored ✓
-
-All matches what the iteration-2 HANDBACK §8 claims. No drift between claim and reality this time.

-## 9. Recommended next steps
+## 8. Recommended next steps (post-merge)
 
-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. **Merge** `feat/v1.1.7-secrets-email` into `main` (fast-forward; branch is linear ahead).
+2. **`docker compose down` when convenient** to tear down the dev Postgres container.
+3. **Pause** before dispatching v1.1.8 (User Management).
+4. **For the v1.1.8 dispatch prompt**, fold in:
+   - **Drop the plaintext `realtime_signing_key` column** (the v1.1.7 phase-2 commitment). Pre-flight check: scan the column for any remaining non-NULL rows; if found, run the encryption migration before the drop migration. Add a CHANGELOG note that v1.1.8 requires v1.1.7 to have been applied first (no skipping versions).
+   - **Clippy --all-targets discipline refinement** (§3.3 finding). Require either a `cargo clean` before `cargo clippy --all-targets` OR explicit verification that test binaries are being checked. v1.1.6's silent regression shows the gate can produce false-green results under cargo's incremental cache. Specific recommendation: add a CI step that asserts the clippy run touched the test binaries (e.g. count `Checking` lines in the output and verify they include test crates).
+   - **`auth_mode = 'session'` for realtime subscriber tokens** — v1.1.7's CHECK constraint on `topics.auth_mode` only allows `('public', 'token')`. v1.1.8 (users::*) needs to add `'session'` and a session-token validator alongside the existing HMAC validator behind the unchanged `RealtimeAuthority` trait.
+   - **Bounded e2e parallelism** — defer the workspace-wide harness refactor (shared pool per binary) until there's a dedicated test-infra release. Until then, CI just needs `--test-threads=2` or smaller for the picloud crate's e2e binaries.
+5. **Awareness from §3.3**: the clippy regression in v1.1.6 was caught by v1.1.7's diligence, but every prior REVIEW.md from v1.1.1 onward should be re-checked if you want certainty that no test-only clippy warnings slipped through. The fix is forward-only — re-running clippy on v1.1.1 through v1.1.6 commits would just confirm the warnings were latent then too.

+# @picloud/client
+
+TypeScript client for [PiCloud](../../README.md). Three capabilities, all
+**script-mediated** — there is no direct KV / docs / users access from the
+browser (the hybrid model, by design):
+
+1. **Typed HTTP** to dev-defined script endpoints.
+2. **SSE realtime** subscriptions to externally-subscribable pub/sub topics.
+3. **Auth-flow helpers** over your own dev-defined login/logout endpoints.
+
+```ts
+import { PicloudClient } from '@picloud/client';
+
+const client = new PicloudClient({
+  baseURL: 'https://api.example.com',
+  getAuthToken: () => localStorage.getItem('auth_token')
+});
+
+// Typed HTTP
+interface CreateUserReq { name: string; email?: string; role: string }
+interface CreateUserRes { id: string; name: string; created_at: string }
+const user = await client
+  .endpoint<CreateUserReq, CreateUserRes>('/api/users')
+  .post({ name: 'alice', role: 'admin' });
+
+// SSE subscription
+const unsubscribe = client.subscribe('chat-room-123', (event) => {
+  console.log('got event:', event.message);
+});
+unsubscribe();
+
+// Token-gated topic (token obtained from one of YOUR script endpoints,
+// which calls `pubsub::subscriber_token`)
+client.subscribe('chat-room-123', cb, { token: 'eyJhbGc...' });
+
+// Auth helpers (call dev-defined endpoints under the hood)
+await client.auth.login('alice@example.com', 'password');
+await client.auth.logout();
+const token = client.auth.token;
+```
+
+## React
+
+```tsx
+import { PicloudProvider, useTopic, useEndpoint } from '@picloud/client/react';
+
+// Wrap your tree once: <PicloudProvider client={client}>…</PicloudProvider>
+
+function ChatRoom({ roomId }: { roomId: string }) {
+  const messages = useTopic<ChatMessage>(`chat-room-${roomId}`);
+  return <ul>{messages.map((m, i) => <li key={i}>{m.text}</li>)}</ul>;
+}
+
+function UserProfile({ id }: { id: string }) {
+  const { data, loading, error } = useEndpoint<UserRes>(`/api/users/${id}`).get();
+  if (loading) return <Spinner />;
+  if (error) return <ErrorView error={error} />;
+  return <div>{data?.name}</div>;
+}
+```
+
+## Svelte
+
+```ts
+import { topicStore, endpointStore } from '@picloud/client/svelte';
+
+const messages = topicStore<ChatMessage>(client, `chat-room-${roomId}`);
+// $messages is an array that grows as events arrive
+
+const userQuery = endpointStore<UserRes>(client, `/api/users/${id}`).get();
+// $userQuery is { data, loading, error }
+```
+
+> The Svelte helpers take the `client` explicitly (a store isn't a component,
+> so there's no React-style context to read).
+
+## Optional runtime validation (zod / valibot)
+
+No hard dependency — the adapter is the `{ parse(input): T }` shape. A Zod
+schema satisfies it directly; wrap Valibot in one line:
+
+```ts
+import { z } from 'zod';
+const UserSchema = z.object({ id: z.string(), name: z.string() });
+const user = await client.endpoint('/api/users/1').get({ validate: UserSchema });
+
+// valibot:
+import * as v from 'valibot';
+const schema = v.object({ id: v.string() });
+const adapter = { parse: (i: unknown) => v.parse(schema, i) };
+```
+
+## Transport notes
+
+- SSE is implemented over streaming `fetch` (not native `EventSource`) so the
+  client can refresh an expired token on a 401, send `Last-Event-ID` on resume,
+  and apply its own exponential backoff (1s → 2s → 4s … capped at 30s).
+- **React Native** has no native `EventSource`, but it also can't stream
+  `fetch` bodies on all engines — if you target RN, supply a streaming-capable
+  `fetch` polyfill via the `fetch` option, or use a `react-native-sse`-based
+  adapter. (Server-side `Last-Event-ID` replay is not implemented in v1.1.6;
+  the client sends the header so it's ready when the server adds replay.)
+
+## Build / test
+
+```sh
+npm install
+npm run lint    # tsc --noEmit (strict)
+npm run test    # vitest
+npm run build   # tsup → dist/ (ESM + CJS + .d.ts)
+```

+//!
+//! 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.

+//! `http::` Rhai bridge — outbound HTTP from scripts (v1.1.4).
+//!
+//! ```rhai
+//! let r = http::get("https://api.example.com/users/123");
+//! let r = http::get(url, #{ headers: #{ "Authorization": "Bearer x" }, timeout_ms: 5000 });
+//! let r = http::post(url, #{ text: "hello" });          // Map body → JSON
+//! let r = http::post(url, "raw", #{ headers: #{ ... } }); // String body → text/plain
+//! let r = http::post_form(url, #{ a: "1", b: "2" });    // form-encoded
+//! let r = http::request("OPTIONS", url);
+//! ```
+//!
+//! **Argument shape (v1.1.4 decision):** body and options are separate
+//! positional arguments — `verb(url, body, opts)` — not body-inside-
+//! opts. This keeps the unknown-opt-key typo guard intact and resolves
+//! the brief's internal contradiction (its Slack example passed a bare
+//! body map). The `opts` vocabulary is exactly
+//! `{headers, timeout_ms, follow_redirects, max_redirects}`; any other
+//! key throws.
+//!
+//! Body dispatch (positional `body`): Map/Array → JSON +
+//! `application/json`; String → raw + `text/plain`; Unit `()` → no
+//! body. GET/HEAD ignore any body.
+//!
+//! Response is a Rhai map `#{ status, headers, body, body_raw }`:
+//! `body` is the parsed JSON when the response is `application/json`
+//! and parses; `()` for an empty body; otherwise the raw string.
+//!
+//! Errors follow `docs/sdk-shape.md`: network/timeout/SSRF/size failures
+//! throw (`"http: <message>"`); a non-2xx status does NOT throw — the
+//! response map is returned, fetch-style.

+//! Cron scheduler — the v1.1.4 time-based trigger source.
+//!
+//! A single tokio task polls `cron_trigger_details` on a tick (default
+//! 30s; `PICLOUD_CRON_TICK_INTERVAL_MS`). For each enabled cron trigger
+//! whose next scheduled fire is due, it enqueues ONE outbox row
+//! (`source_kind = 'cron'`) and updates `last_fired_at` — both in the
+//! same transaction, claimed via `FOR UPDATE SKIP LOCKED` so a future
+//! multi-node deploy can't double-fire.
+//!
+//! The scheduler does NOT dispatch or touch the `ExecutionGate`: it only
+//! enqueues. The existing dispatcher picks the row up and acquires the
+//! gate exactly as it does for kv/docs/dead_letter rows.
+//!
+//! **Catch-up policy (matches the brief):** a trigger that missed N fire
+//! windows since `last_fired_at` fires exactly ONCE on the next tick,
+//! not N times. This falls out of the design: [`next_due`] returns a
+//! single canonical scheduled time (the first slot after the reference
+//! point), and after firing we set `last_fired_at = now`, so the next
+//! tick computes from `now` and sees only future slots. Backfilling
+//! missed windows is intentionally out of scope (an explicit replay
+//! action is the v1.2+ escape hatch).

+//! backing the dashboard's files view (v1.1.5).
+//!
+//! Two operations only, both operator-facing:
+//!   * `GET  /apps/{id}/files?collection=<c>&cursor=&limit=` — list file
+//!     metadata for a collection (cursor-paginated).
+//!   * `DELETE /apps/{id}/files/{collection}/{file_id}` — remove a file.
+//!
+//! These talk to the `FilesRepo` directly (like `triggers_api` talks to
+//! `TriggerRepo`), guarded by the same capability model as the SDK
+//! (`AppFilesRead` / `AppFilesWrite`). **Admin deletes do NOT emit a
+//! `files:delete` trigger event** — they're operator cleanup actions,
+//! not script mutations (see HANDBACK §7). The capability binds to the

+//! `FilesRepo` — the metadata row (Postgres) + blob bytes (filesystem)
+//! storage layer for the v1.1.5 `files::*` SDK.
+//!
+//! Unlike KV/docs, this repo owns BOTH halves of a file: the `files`
+//! row (metadata + SHA-256 checksum) and the bytes on disk at
+//!   `<root>/files/<app_id>/<collection>/<id[0:2]>/<id>`.
+//! It owns both because the write must be atomic across them — a crash
+//! mid-write must never leave a readable half-written file.
+//!
+//! ## Atomic write protocol (`create` / `update`)
+//!   1. Validate (collection path-safety; caps live one layer up).
+//!   2. `create_dir_all` the shard dir with `0o700`.
+//!   3. SHA-256 the in-memory bytes (single pass) while writing to
+//!      `<final>.tmp.<unique>`.
+//!   4. `fsync` the temp file.
+//!   5. `rename` temp → final (atomic on POSIX).
+//!   6. `fsync` the parent dir (so the rename is durable).
+//!   7. INSERT / UPDATE the DB row.
+//!
+//! A crash between 1–5 leaves an orphan `*.tmp.*` (never read). A crash
+//! between 5–7 leaves a file with no row — never reachable via the SDK
+//! (reads start from the row). Both are reclaimed by a future orphan
+//! sweep (deferred to v1.1.6+; see HANDBACK §7).
+//!
+//! ## Atomic delete protocol
+//!   1. SELECT + DELETE the row inside one transaction; commit.
+//!   2. `unlink` the file (outside the tx). A failure here leaves an
+//!      orphan; a failure before the commit changes nothing.
+//!
+//! ## Checksum-on-read
+//! `get` reads the file, hashes it, and compares against the stored
+//! checksum — returning `FilesError::Corrupted` (and logging the path
+//! at error level) on a mismatch. It never auto-deletes; the operator
+//! decides what to do with a metadata-vs-bytes divergence.

+//! `FilesServiceImpl` — wires the `FilesRepo` underneath the
+//! `picloud_shared::FilesService` trait scripts see via the Rhai
+//! bridge.
+//!
+//! Layers added here (vs the raw repo), mirroring `KvServiceImpl`:
+//!   1. Collection validation (empty + path-traversal) and field /
+//!      size-cap validation at the SDK boundary.
+//!   2. **Script-as-gate authz**: when `cx.principal.is_some()` we run
+//!      `authz::require(...)`; when it's `None` (public HTTP) we skip.
+//!      Cross-app isolation is unaffected — every repo call is keyed by
+//!      `cx.app_id`, never an argument.
+//!   3. `ServiceEvent` emission after each mutation (`create` /
+//!      `update` / `delete`). The payload is the file **metadata**, not
+//!      the blob bytes (files are too big for trigger payloads).

+//! Orphan `*.tmp.*` blob sweeper (v1.1.6, v1.1.5 follow-up).
+//!
+//! The files repo writes blobs atomically: it streams into a
+//! `<id>.tmp.<pid>-<seq>` temp file, fsyncs, then renames to the final
+//! `<id>` path. A crash between create and rename leaves an orphan temp
+//! file that is never read and never reclaimed. This sweeper deletes
+//! those: every `PICLOUD_FILES_ORPHAN_SWEEP_INTERVAL_SEC` (default 6h) it
+//! walks `<root>/files/` and unlinks any `*.tmp.*` file older than
+//! `PICLOUD_FILES_ORPHAN_TMP_TTL_SEC` (default 1h).
+//!
+//! Deliberately bounded: it does NOT cross-check on-disk files against DB
+//! rows (the full reconciling sweeper is v1.3+). It only targets the temp
+//! files, which are unambiguously orphans once past the TTL — no live
+//! writer keeps one around for an hour.

+//! Mirrors the v1.1.1+ stateful-service shape (`KvServiceImpl`):
+//! script-as-gate authz (`AppHttpRequest`, skipped when
+//! `cx.principal` is `None`), with the backend talking to the network
+//! instead of Postgres. The reqwest client is built once at startup

+//! including each redirect hop, since redirects are followed manually
+//! through the same client.
+//!
+//! Layering vs the raw client:
+//!   1. URL validation: scheme must be http/https; ports 22/25/465/587
+//!      are blocked. (IP-level filtering is the resolver's job.)
+//!   2. Body-size caps on both request and response (stream-with-cap on
+//!      the response, checking `Content-Length` first).
+//!   3. Total-request timeout (default 30s, max 60s) on top of the
+//!      client's 10s connect timeout.
+//!   4. Default `User-Agent` unless the caller set one.

+//! `RealtimeAuthorityImpl` — the DB-backed SSE subscribe gate (v1.1.6).
+//!
+//! Backs the [`picloud_shared::RealtimeAuthority`] trait the SSE handler
+//! in orchestrator-core calls. All `topics`-table reads and signing-key
+//! material stay inside this impl so the data-plane crate never touches
+//! the key.
+//!
+//! Verdict mapping (see [`SubscribeDenied`]):
+//!   * topic missing OR not externally subscribable → `NotFound` (404).
+//!     Both collapse to 404 so the endpoint can't probe internal topics.
+//!   * `auth_mode = 'public'` → allow.
+//!   * `auth_mode = 'token'` → verify the HMAC token (present, signed by
+//!     this app's key, unexpired, scoped to this topic) → allow, else
+//!     `Unauthorized` (401, generic — never says which check failed).
+//!
+//! Signing keys never change in v1.1.6 (no rotation API), so a small
+//! in-memory cache avoids a per-subscribe DB read once an app's key has
+//! been seen. The cache is purely an optimization — a cold miss reads
+//! the row.

+//! `SecretsServiceImpl` — wires the `SecretsRepo` underneath the
+//! `picloud_shared::SecretsService` trait that scripts see via the Rhai
+//! bridge.
+//!
+//! Layers added here (vs the raw repo):
+//!
+//! 1. Name validation (non-empty, ≤255 bytes) at the SDK boundary.
+//! 2. **Script-as-gate authz**: when `cx.principal.is_some()` we run
+//!    `authz::require(...)`; when it's `None` (public unauthenticated
+//!    HTTP) we skip the check. Cross-app isolation is unaffected — every
+//!    query is keyed by `cx.app_id`, never an argument.
+//! 3. **JSON ⇄ ciphertext**: `set` serializes the value to JSON bytes,
+//!    enforces the per-secret size cap, and AES-256-GCM-seals it; `get`
+//!    decrypts and deserializes back to the same JSON shape (a String
+//!    round-trips to a String, not a JSON-quoted `"\"…\""`).
+//!
+//! Deliberately **no `ServiceEvent` emission** — secret writes do not
+//! fire triggers (footgun avoidance; see `docs/sdk-shape.md` + the
+//! v1.1.7 brief §2).

+//! The policy is applied to the **resolved IP address**, not the
+//! hostname. That is the DNS-rebinding defense: a hostname that

+//! time is not exploitable, because reqwest re-runs every connection
+//! (including post-redirect hops) through [`SsrfResolver`], which
+//! filters the address list before the socket is opened.
+//!
+//! [`SsrfPolicy::check`] returns a CIDR-*category* reason on denial
+//! (e.g. `"loopback"`, `"private"`) — never the IP itself, so the
+//! script-visible error can't be used to map the internal network.
+//!
+//! `PICLOUD_HTTP_ALLOW_PRIVATE=true` flips `allow_private`, which
+//! short-circuits every check to allow. That is dev/test-only and the
+//! binary logs a startup warning when it's set.
