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

-## §3 Files implementation notes
-
-**Service layering** (`FilesServiceImpl`, manager-core): validate collection (empty + traversal) → script-as-gate authz (`AppFilesRead`/`AppFilesWrite`, skipped when `cx.principal` is `None`) → field/size-cap validation → repo call keyed by `cx.app_id` → best-effort `ServiceEvent` emit. `executor-core` has **no** Postgres or filesystem dependency — both traits live in `picloud-shared`, the impl in manager-core.
-
-**Atomic-write protocol** (`write_atomic_at`, a free fn so it's unit-testable without a pool):
-1. Validate collection path-safety (defensive — already enforced at the SDK boundary).
-2. `create_dir_all` the shard dir `<root>/files/<app_id>/<collection>/<id[0:2]>/<id>` with `0o700` (Unix `DirBuilderExt::mode`).
-3. SHA-256 the in-memory bytes (single pass — never re-reads the file) while writing to `<final>.tmp.<pid>-<atomic-counter>`.
-4. `sync_all()` the temp file.
-5. `rename(tmp, final)` — atomic on POSIX.
-6. `sync_all()` the parent dir (rename durability).
-7. INSERT/UPDATE the DB row.
-
-Rollback per step: crash in 1–5 → orphan `*.tmp.*` (never read; the pid+counter suffix avoids collisions); crash in 5–7 → bytes with no row, **never reachable via the SDK** because every read starts from the row. `update` reads the prior row first (existence + CDC `prev`), writes new bytes, then UPDATEs.
-
-**Atomic-delete protocol** (`FsFilesRepo::delete`): `SELECT … FOR UPDATE` + `DELETE` in one transaction → commit → `unlink` outside the tx. Unlink failure leaves an orphan (logged at warn); failure before commit changes nothing. Returns the deleted metadata so the service can emit.
-
-**Path-traversal validation:** `picloud_shared::validate_files_collection` rejects empty / `/` / `\` / `..` / NUL at the SDK boundary; `FsFilesRepo::guard_collection` repeats it before any fs op. UUID ids can't produce traversal (verified defensively).
-
-**Per-call SHA-256:** computed once over the in-memory `Vec<u8>` during the write (`sha2::Sha256`), hex-lowercased, stored on the row. The file is never re-read to hash. Known-vector tests pin `SHA-256("abc")` and `SHA-256("")`.
-
-**Checksum-on-get:** `get` reads the file, re-hashes, compares to the stored checksum. Mismatch (or missing bytes while the row persists) → `FilesError::Corrupted`, logged at error level with the path, **no auto-delete**. To scripts this surfaces as a thrown Rhai error `"files: file content corrupted (checksum mismatch)"`.
-
-## §4 Pub/Sub implementation notes
-
-**Fan-out-at-publish-time, transactional** (`PostgresPubsubRepo::fan_out_publish`): one transaction — `SELECT` all enabled pubsub triggers for the app (joined to `pubsub_trigger_details`), filter by `topic_matches` in Rust, INSERT one `outbox` row (`source_kind='pubsub'`) per survivor, commit once. A mid-fan-out failure rolls back every row (no half-fan-out). Each delivery row then retries/dead-letters independently through the unchanged dispatcher (its trigger arm just gained `| OutboxSourceKind::Pubsub`).
-
-**Topic pattern matching** runs in Rust (`picloud_shared::topic_matches`), not SQL: `"*"` → all; `"<prefix>.*"` → `starts_with("<prefix>.")`; otherwise exact. `validate_topic_pattern` (used at trigger creation in the admin endpoint and defensively in the repo) accepts only `*` / `<prefix>.*` / no-star-exact, rejecting `*.created`, `**`, `a.*.b`, `user.*x`, etc. with `"unsupported pubsub topic pattern: …"`.
-
-**No matching trigger → the publish succeeds, zero outbox rows** (the design-notes-preferred succeed-silently). `published_at` is stamped manager-side (`Utc::now()`) so every delivery agrees on one instant. `ctx.event.pubsub = #{ topic, message, published_at }`, `ctx.event.op = "publish"`.
-
-There is **no `list_matching_pubsub` on `TriggerRepo`** — pubsub publishes directly (it's not a `ServiceEvent`), so the fan-out SELECT lives in `pubsub_repo`, not the `OutboxEventEmitter`. This is the one structural asymmetry vs files/kv/docs, intentional per the publish-time-fan-out decision.
-
-## §5 CI follow-up (§6) status
-
-- **Pre-existing CI:** none (no `.github/`, no `.gitlab-ci.yml`).
-- **§6a (added):** `.github/workflows/ci.yml` — a `rust` job with a `postgres:15` service (`DATABASE_URL=postgres://picloud:picloud@localhost:5432/picloud`) running `cargo fmt --all -- --check`, `cargo clippy --all-targets --all-features -- -D warnings`, `cargo test --workspace`; a separate `dashboard` job running `npm ci` + `npm run check`.
-- **§6b (done):** `schema_snapshot.rs` is no longer `#[ignore]`'d. Reworked from `#[sqlx::test]` to `#[tokio::test]` that **skips cleanly when `DATABASE_URL` is unset** (chosen over fail-loud so `cargo test --workspace` stays green locally) and otherwise connects, runs `sqlx::migrate!`, and dumps. Golden `expected_schema.txt` re-blessed (now contains `files`, `files_trigger_details`, `pubsub_trigger_details`, both widened CHECKs, `idx_files_app_collection`, `idx_triggers_app_pubsub_enabled`, and migrations 0018–0020).
-  - **Tradeoff (documented):** the non-`sqlx::test` path applies migrations against the `DATABASE_URL` database directly rather than an isolated throwaway DB. Migrations are forward-only/idempotent and CI's Postgres is fresh, so the structural dump is identical; locally it will also apply 0018–0020 to whatever DB you point at.
-
-## §6 Schema decisions beyond the brief
-
-- `files` table is verbatim from the brief. `files_trigger_details` / `pubsub_trigger_details` mirror `kv_trigger_details` / `cron_trigger_details`.
-- `pubsub_trigger_details` has no `ops` column (a publish has a single implicit op) — only `topic_pattern`.
-- `idx_triggers_app_pubsub_enabled` is the third partial index of its kind (per the brief's note); deliberate duplication.
-
-## §7 Decisions beyond the brief (every prompt-default deviation)
-
-1. **Empty blob treated as a missing `data` field.** `NewFile::validate` / `FileUpdate::validate` reject 0-byte `data` with `FilesError::MissingField("data")`. The brief lists `data` as required and tests "missing … data"; the cleanest testable interpretation at the service layer is "empty == missing". Consequence: v1.1.5 cannot store an intentionally-empty file. Easy to relax later.
-2. **Admin files REST API added** (`files_api.rs`: `GET /apps/{id}/files?collection=…`, `DELETE /apps/{id}/files/{collection}/{file_id}`). The brief's §5 dashboard needs a backend but didn't spell out admin endpoints; I added a minimal one mirroring `triggers_api`'s direct-repo + capability pattern (`AppFilesRead` for list, `AppFilesWrite` for delete).
-3. **Admin file delete does NOT emit a `files:delete` trigger event.** It's an operator cleanup action, not a script mutation, so it goes straight to the repo. SDK deletes still emit. Flagging because "every successful mutation emits" could be read to include admin deletes.
-4. **Files `list` bridge accepts both positional and map forms** — `list()`, `list(cursor)`, `list(cursor, limit)`, and `list(#{ cursor, limit })` (the map form the brief's example used). Additive convenience.
-5. **Files collection-glob semantics reuse the existing `collection_matches`** (`*` / `foo*` prefix / exact), identical to kv/docs. The brief mentioned a `"prefix:*"` form in one spot; I kept parity with the established kv/docs matcher rather than introduce a new glob dialect.
-6. **schema_snapshot runs against the live `DATABASE_URL` DB** rather than an isolated temp DB (see §5).
-7. **Orphan sweep deferred to v1.1.6+** — confirmed with the user during planning (the brief's recommended default). No `*.tmp.*` sweeper daemon shipped.

+
+## 2. Encryption infrastructure notes
+
+- **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.
+
+---
+
+## 3. Secrets notes
+
+- `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).
+
+---
+
+## 4. Email implementation notes
+
+- **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.
+
+---
+
+## 5. Dead-letter handler fix notes
+
+- **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).
+
+---
+
+## 6. Realtime signing-key migration notes
+
+- **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.
+
+---
+
+## 7. Decisions beyond the brief / deviations flagged
+
+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.
+
+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.
+
+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.
+
+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.
+
+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.
+
+No other deviations from prompt-specified defaults.

+All gates run on the handed-back HEAD (`a7d3dad`):

-  cargo test -p picloud-manager-core --test schema_snapshot   → test result: ok. 1 passed
+Full test run **with `DATABASE_URL` set** so the DB-gated suites
+(schema_snapshot, dispatcher_e2e ×9, email_inbound ×8) execute:
+
+```sh
+DATABASE_URL='postgres://picloud:picloud@127.0.0.1:15432/picloud' \
+  cargo test --workspace -- --test-threads=2
 ```
-Migrations 0018–0020 applied cleanly on top of the existing v1.1.4 dev DB during the re-bless — the same `sqlx::migrate!` replay CI runs on a fresh Postgres.
 
-Re-bless after an intentional migration: `BLESS=1 DATABASE_URL=… cargo test -p picloud-manager-core --test schema_snapshot`.
+**Pass count, summed from cargo's literal output (NOT hand-counted):**
 
-**Not run this session:** the full running-binary manual smoke (a script that does `files::collection("uploads").create(...)` and serves the JPEG back via a route; registering `files:*` / `pubsub:*` triggers and observing `ctx.event`). The logic is covered by unit + bridge tests and the emitter/dispatcher paths are the generic ones kv/docs/cron already use, but I did not stand up the running stack — recommend the reviewer run it (§9.2).
+```sh
+DATABASE_URL=... cargo test --workspace -- --test-threads=2 2>&1 | \
+  awk '/test result: ok\./ { gsub(";", ""); sum += $4 } END { print sum }'
+# => 617
+```
 
-## §9 Open questions for the reviewer
+**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).
 
-1. **Orphan sweep** — deferred to v1.1.6+ per the planning decision. Confirm shipping v1.1.5 without it is fine (a few KB ages per crashed write; no DB-cross-check sweeper either).
+**Bounded-parallelism note (`--test-threads=2`):** the picloud e2e
-2. **Test count 63 vs the 70–90 target.** Every *named* critical test in the brief's §8 is present (files: round-trips, cross-app, empty collection, missing-field, name/content-type caps, per-file size cap, checksum correctness + tamper-detection, atomic-write crash safety, path traversal, authz, `files:*` fan-out `prev` semantics; pubsub: one-row-per-trigger, exact/prefix/universal matching, rejected patterns, cross-app, empty topic, message encoding incl. blob→base64, transactional rollback, multiple matches). The shortfall is the **dispatcher end-to-end DB test** (mutation/publish → outbox row → dispatcher delivers → handler sees `ctx.event`). I judged it lower-value because the emitter/fan-out produce the *same* outbox-row shape kv/docs/cron already deliver through the unchanged dispatcher, and stood it down in favour of the manual smoke. Want a `DATABASE_URL`-gated integration test added for it?
+binaries each call `build_app`, which opens its own Postgres pool. Under
-3. **Empty-blob = missing-data** (§7.1) — acceptable, or should empty files be storable?
+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).
 
-## §10 Latent security findings
+**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.
 
-None new. Checked specifically: (a) cross-app isolation is keyed on `cx.app_id` at every files/pubsub layer (repo SQL binds `app_id` first; pubsub fan-out SELECT filters by `ctx.app_id`); tests assert app A can't see/fire app B's files/triggers. (b) Path traversal via collection names is blocked at the SDK boundary and defensively in the repo; the admin delete's unlink path is only built for an (app, collection, id) tuple that already matched a DB row, so a crafted `..` segment can't unlink arbitrary files. (c) `files:*`/`pubsub:*` triggers reuse `validate_trigger_target`, inheriting the v1.1.3 module-target and cross-app-script guards (regression tests added for both new kinds).
+**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).
 
-## §11 Deferred items (per brief Scope-OUT + orphan-sweep decision)
+---
 
-`publish_ephemeral` (v1.2), per-app storage quotas (v1.2), file dedup (v1.2+), presigned URLs / external download tokens (v1.1.6+), streaming up/download (Rhai is sync), file-level ACLs (v1.2+), mid-pattern wildcards (v1.2), topic ACLs / external subscription / `topics` table (v1.1.6), realtime SSE (v1.1.6), and the **orphan-file sweep daemon** (v1.1.6+ — confirmed deferred).
+## 9. Open questions for the reviewer
 
-## §12 Known limitations / rough edges
+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.
 
-- **No orphan reclamation** — crashed writes leave `*.tmp.*`; rename-completed-but-DB-failed leaves unreferenced bytes. Both are harmless (never SDK-readable) but accumulate until v1.1.6's sweeper.
+---
-- **Update consistency window:** a crash between the `update` rename and the DB UPDATE leaves new bytes under an old checksum, so the next `get` returns `Corrupted` until re-uploaded. This is the brief's accepted step-5–7 window, surfaced honestly.
+
-- **Pub/sub fan-out holds one transaction across all subscribers** — fine at v1.1.x scale; a topic-trie index is the v1.2 escape hatch if it becomes a hot path.
+## 10. Latent security / correctness findings
-- **Files admin view requires the operator to type a collection name** (no collection-enumeration endpoint) — minimal by design.
+
-- **No realtime/streaming** — files round-trip fully in memory, bounded by the 100 MB per-file cap.
+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 v1.1.5.**
+**APPROVE — ready to merge to `main` as v1.1.7.**
 
-Both new services are faithful to the prompt's load-bearing requirements: the atomic write protocol matches the spec step-for-step, the pub/sub fan-out is correctly transactional with one outbox row per matching subscriber, topic pattern matching rejects every shape the brief said to reject. The commit split is cleanly per-feature (3 commits vs v1.1.4's single mega-commit — the agent acted on the v1.1.4 retro lesson without being asked). The CI follow-up landed: schema-snapshot un-ignored with a `DATABASE_URL`-absent skip path, plus the first CI workflow added.
+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.
 
-Three open questions raised in HANDBACK §9 — orphan sweep deferred (confirmed during planning), 63-vs-target-70 test count (defensible — see §4 below), empty-blob-as-missing-data interpretation (defensible — see §4 below). None are blockers.
+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
 
-**1. The commit split.** v1.1.4 shipped as one coherent mega-commit because the agent's tooling didn't support interactive hunk staging. The v1.1.4 retro implicitly raised the question. The v1.1.5 agent split the work cleanly into `feat(v1.1.5): files SDK + files:* triggers` → `feat(v1.1.5): pubsub::publish_durable SDK + pubsub:* triggers` → `chore(v1.1.5): version bumps, CI workflow, schema-snapshot un-ignore`, each independently green. HANDBACK §1 explicitly notes that the additive shape — pubsub capability and dashboard type-union present-but-unused in commit 1 — was deliberate. This is the right shape for trunk-based review.
+### 3.1 Brief-internal contradiction: `TriggerEvent::DeadLetter` field names (HANDBACK §7 #2)
 
-**2. The atomic write protocol is implemented exactly to spec.** Steps 2–6 live in `write_atomic_at` ([files_repo.rs:244-277](crates/manager-core/src/files_repo.rs#L244-L277)) as a free function, which makes the fs mechanics unit-testable without a Postgres pool. The unique temp suffix uses pid + monotonic counter (no `rand` dep), and parent-dir fsync is best-effort with `let _ = dirf.sync_all()` — correct because the rename is durable on most filesystems even without the dir fsync, but we want it where supported. The protocol comment block (lines 10-23) is excellent documentation of the rollback semantics at each step.
+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}`.
 
-**3. The pub/sub fan-out is correctly transactional.** [pubsub_repo.rs:70-117](crates/manager-core/src/pubsub_repo.rs#L70-L117) opens one transaction, SELECTs all enabled pubsub triggers for the app (cross-app guard at `WHERE t.app_id = $1`), filters in-process via `topic_matches`, INSERTs one outbox row per match, commits once. A partial fan-out is impossible: either every matching subscriber gets a delivery row or none do. `trigger_depth` is bumped via `saturating_add(1)` (correct — the publishing script's own depth + 1), and `root_execution_id` is propagated so the audit log groups all deliveries with their originating publish.
+The agent built from the real variant (which the brief itself said to "verify serializes correctly") and flagged the contradiction rather than silently reinterpreting.
 
-**4. Topic pattern matching is clean and precise.** The `topic_matches` implementation ([shared/pubsub.rs:65-74](crates/shared/src/pubsub.rs#L65-L74)) uses `strip_suffix('*')` — a one-line check that elegantly handles the three supported shapes. Crucially, `"user.*"` strips to `"user."` (including the dot), so `topic_matches("user.*", "users.created")` correctly returns false. `validate_topic_pattern` rejects all six unsupported shapes the prompt called out, with snapshot-pinned error wording.
+**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.
 
-**5. Path traversal defense in depth.** `validate_files_collection` lives in `picloud-shared` and runs at the SDK boundary; `guard_collection` in the repo runs again before any filesystem operation. Both reject empty, `/`, `\`, `..`, NUL. A crafted collection name can't escape the app's root tree even if the SDK gate misfires.
+### 3.2 `inbound_secret` stored encrypted (HANDBACK §7 #1)
 
-**6. Discipline carryover.** Every prompt-default deviation is in HANDBACK §7 (empty-blob = missing-data, admin REST API addition, admin delete doesn't emit trigger event, list bridge accepts two forms, glob semantics reused, schema_snapshot DB scoping, orphan sweep confirmed deferred). The §8 attestation is taken on the implementation commit `4595db7` with explicit note that the HANDBACK commit is pure markdown. The v1.1.2/v1.1.3/v1.1.4 retro lessons stuck.
+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.
 
-**7. CI workflow lands.** This is the first `.github/workflows/ci.yml` in the project — the v1.1.4 retro recommendation acted on without prompting. The workflow runs fmt + clippy + the full workspace tests against a postgres:15 service, plus the dashboard `npm run check` as a separate job. Schema golden silent drift across v1.1.1–v1.1.3 is now a regression the CI catches automatically.
+**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.
 
-**8. Schema-snapshot skip path is well-judged.** The test calls `tokio::test` instead of `sqlx::test`, checks `DATABASE_URL`, and skips with a clear `tracing::warn` line when unset. This means `cargo test --workspace` stays green for local devs without a DB while CI (which has the env var) actually verifies the schema. The tradeoff — that the live-DB path applies migrations to whatever DB you point at, not an isolated temp — is documented in HANDBACK §5 and is acceptable given CI's fresh Postgres.
+**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.
 
-## 4. Open questions answered
+### 3.3 Latent finding: clippy `--all-targets` regression (HANDBACK §10 #1)
+
+This is the most important finding in this review.
+
+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
+
+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.
+
+**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:
 
-### 4.1 Orphan-sweep deferral
+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.
 
-**Verdict: accept.** Confirmed during planning. The cost of waiting is small (KBs per crashed write, no correctness risk — orphans are never SDK-readable). Defer to v1.1.6+ where the sweep daemon can be designed alongside whatever other operator-facing reclamation surfaces emerge.
+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.
 
-### 4.2 Test count 63 vs the 70-90 target
+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.
 
-**Verdict: accept the undershoot.**
+## 6. Smaller observations
 
-The agent's argument is sound: every named critical test in the prompt's §8 is present (atomic write rollback, checksum tampering, cross-app, path traversal, authz, fan-out transactional rollback, topic pattern shapes including all six rejections, multiple-matches, blob-to-base64). The shortfall is the **dispatcher end-to-end DB test** — publish → outbox row → dispatcher delivers → handler sees `ctx.event`.
+- **`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.
 
-But: that end-to-end path is *entirely* through code that v1.1.1/v1.1.2/v1.1.4 already exercise. The dispatcher's `Files | Pubsub` match-arm extension is a one-line change. The handler's `ctx.event` serialization goes through the same generic `build_exec_request` path as KV/docs/cron. Adding a v1.1.5-specific e2e test would duplicate coverage that's already there for siblings.
+## 7. Versioning audit
-
-If we wanted dispatcher e2e tests, they should be a workspace-wide effort (one test per trigger kind, gated on `DATABASE_URL`, picking up the new CI workflow's Postgres). That's a meaningful follow-up — worth flagging for v1.1.6 — but not v1.1.5's problem.
-
-### 4.3 Empty-blob = missing-data
-
-**Verdict: accept the deviation; relaxable later.**
-
-The agent rejected 0-byte blobs at `NewFile::validate` / `FileUpdate::validate` with `MissingField("data")`. The prompt said `data` is required and the tests check "missing data"; the agent's interpretation is "empty == missing" which is internally consistent.
-
-The cost: v1.1.5 can't store an intentionally-empty file. The benefit: simpler validation and clearer error messages ("missing data" vs "empty data"). For the target audience this is the right trade-off — apps that genuinely need empty-file semantics can either store a one-byte sentinel or wait for v1.2 to relax it. Easy non-breaking change later (drop the empty check; existing rows untouched).
-
-Flag for v1.1.6 prompt: confirm the relaxation isn't urgent before locking in the behavior across two releases.
-
-## 5. Smaller observations (no action required)
-
-- **Admin file-delete bypasses `files:delete` trigger emission.** HANDBACK §7 #3 flagged this. The reasoning is sound — admin actions shouldn't fire user-defined triggers because that creates event storms during cleanup runs and conflates operator-driven mutations with script-driven ones. SDK deletes still emit; only the admin REST endpoint skips. Reasonable.
-- **Admin files REST API addition** ([files_api.rs](crates/manager-core/src/files_api.rs)) was needed to back the dashboard view. Mirrors `triggers_api`'s direct-repo + capability pattern. HANDBACK §7 #2 flagged it.
-- **`files` `list` bridge accepts both positional and map forms** (HANDBACK §7 #4). Additive convenience; the map form matches the prompt's example. Fine.
-- **Collection-glob dialect reuses the existing `collection_matches`** (`*` / `foo*` prefix / exact) instead of introducing a new `"prefix:*"` form. Right call — keeping parity with KV/docs trigger semantics. HANDBACK §7 #5 flagged it.
-- **`shared::pubsub::NoopPubsubService`** is added for the executor-core integration test harness — every call returns `PubsubError::Unavailable`. Same pattern as the existing `NoopEventEmitter`. Clean.
-- **The publish saturating-add for `trigger_depth`** ([pubsub_repo.rs:107](crates/manager-core/src/pubsub_repo.rs#L107)) means a publish from depth-`u32::MAX` won't panic. That's already capped by `PICLOUD_MAX_TRIGGER_DEPTH` (default 8) at the dispatcher, but defensive overflow handling is correct.
-- **`shared/src/pubsub.rs` tests** include four named cases (exact, prefix wildcard, universal, validation) with subcases — clean test taxonomy.

-## 7. Recommended next steps (post-merge)
+## 8. Recommended next steps (post-merge)
 
-1. **Merge** `feat/v1.1.5-files-pubsub` into `main` (fast-forward; branch is linear ahead).
+1. **Merge** `feat/v1.1.7-secrets-email` into `main` (fast-forward; branch is linear ahead).
-2. **Pause** before dispatching v1.1.6 (Realtime Channels & Client Library — the co-shipped SSE + `@picloud/client` work).
+2. **`docker compose down` when convenient** to tear down the dev Postgres container.
-3. **For the v1.1.6 dispatch prompt**, consider folding in:
+3. **Pause** before dispatching v1.1.8 (User Management).
-   - **Dispatcher end-to-end DB tests** for each trigger kind. This is broader than v1.1.5 — it's a workspace-wide hygiene task. Now that CI has a Postgres service (per v1.1.5's `.github/workflows/ci.yml`), gating these tests on `DATABASE_URL` lets them run in CI without breaking local `cargo test`. Cost is bounded; the goal is to catch dispatcher regressions before they surface as production trigger silence.
+4. **For the v1.1.8 dispatch prompt**, fold in:
-   - **Empty-blob storage** — revisit whether `data: 0 bytes` should be a valid stored state (currently rejected as missing). Decide before v1.1.6 ships so the semantics across two releases stay consistent.
+   - **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).
-   - **Orphan file sweeper** — design + ship the simple `*.tmp.*` sweeper (defer the full DB-cross-check version to v1.3+). v1.1.6 is when the file storage will start to accumulate enough that operators notice.
+   - **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).
-4. **Awareness:** v1.1.5 is the first release where the CI workflow exists. If the project lands new contributors before v1.1.6, the workflow needs `secrets` review (none currently set) and possibly branch-protection rules pointing at the CI checks.
+   - **`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.
 
 Branch is ready for merge. Verdict: **APPROVE**.

+TypeScript client for [PiCloud](../../README.md). Three capabilities, all

+
+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.
+

+  getAuthToken: () => localStorage.getItem('auth_token')

+
+## 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:

+## 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

+//! Rhai `email::{send,send_html}` bridge.
+//!
+//! Layers added here:
+//!
+//! 1. **Script-as-gate authz**: `AppEmailSend` checked when
+//!    `cx.principal.is_some()`; skipped for public-HTTP (`None`).
+//! 2. Required-field + RFC 5322-ish address validation at the boundary.
+//! 3. Per-message size cap (default 25 MB).
+//! 4. **Disabled mode**: if no SMTP relay is configured (HOST/USER/
+//!    PASSWORD not all set) every `send` returns `NotConfigured` and
+//!    startup logs a warning — there is no silent drop.
+//!
+//! Connection model: one connection per call (lettre's default). A
+//! pooled transport is a v1.2+ optimization. Per-app `from` validation /
+//! SPF / DKIM are the operator's responsibility at the relay (v1.1.7
+//! does not restrict the `from` address).

+//! `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).

+//! In-process `RealtimeBroadcaster` — the SSE fan-out registry (v1.1.6).
+//!
+//! Sibling of [`crate::inbox::InboxRegistry`], but multi-receiver and
+//! repeated-event: a `Mutex<HashMap<(AppId, topic), broadcast::Sender>>`
+//! over `tokio::sync::broadcast` instead of a oneshot map. The publish
+//! side ([`PubsubServiceImpl`]) and the SSE subscribe side both hold one
+//! shared `Arc<InProcessBroadcaster>`.
+//!
+//! Delivery is best-effort: each channel has a bounded buffer
+//! (`PICLOUD_REALTIME_BROADCAST_CAPACITY`, default 64); a slow consumer
+//! that falls behind sees the oldest events dropped (standard
+//! `broadcast` lag semantics — the receiver gets `RecvError::Lagged`).
+//! SSE's transport-layer auto-reconnect is the recovery path; there's no
+//! server-side replay in v1.1.6.
+//!
+//! Channels are created lazily on first subscribe. A periodic GC task
+//! ([`spawn_realtime_gc`]) drops senders whose receiver count has fallen
+//! to zero so one-shot subscribers don't grow the map unboundedly.
+//!
+//! Cluster mode (v1.3+) swaps this for a Postgres `LISTEN/NOTIFY`-backed
+//! resolver behind the same `RealtimeBroadcaster` trait.

+//! SSE realtime endpoint — `GET /realtime/topics/{topic}` (v1.1.6).
+//!
+//! This is a data-plane surface, deliberately NOT under `/api/`
+//! (realtime is its own versioning surface per the path scheme). It is
+//! merged at the router root by the `picloud` binary alongside
+//! `/healthz`, `/version`, and the user-route fallback.
+//!
+//! Handshake:
+//!   1. Resolve `Host` → `app_id` (two-phase dispatch). No app → 404.
+//!   2. Extract the token from `Authorization: Bearer <t>` OR `?token=<t>`
+//!      (EventSource can't set custom headers, so the query form is the
+//!      browser-compatible path).
+//!   3. Ask the injected [`RealtimeAuthority`]: missing/internal topic →
+//!      404, bad/absent token on a token-gated topic → 401, otherwise OK.
+//!   4. Acquire a `broadcast::Receiver` and stream events as SSE until
+//!      the client disconnects (dropping the receiver — the broadcaster
+//!      cleans up on its own).
+//!
+//! Heartbeats (`:` comment lines) keep idle proxies from closing the
+//! connection; interval is `PICLOUD_REALTIME_HEARTBEAT_SEC` (default 30).

+//! End-to-end dispatcher tests — one per trigger kind (v1.1.5 follow-up,
+//! landed in v1.1.6). Each test wires the full all-in-one app via
+//! `build_app` (which spawns the real dispatcher + cron scheduler +
+//! executor), creates an app + a logging handler script + a trigger,
+//! causes the originating event, and polls for the handler's side effect.
+//!
+//! ## Gating
+//!
+//! These need a Postgres reachable via `DATABASE_URL`. They follow the
+//! `schema_snapshot` pattern (NOT `#[ignore]`): when `DATABASE_URL` is
+//! unset the test prints a notice and returns early, so plain
+//! `cargo test` stays green locally while CI (which sets `DATABASE_URL`)
+//! runs them.
+//!
+//! ## How "the handler fired" is observed
+//!
+//! The dispatcher does not write `execution_log` rows for trigger
+//! handlers, so each handler instead records its `ctx.event` into a KV
+//! marker (`collection = "e2e_markers"`, which no trigger watches — no
+//! recursion). The test polls `kv_entries` for that marker and asserts
+//! the event shape. See HANDBACK §deviations for why this lives in
+//! `picloud/tests/` rather than `manager-core/tests/` (build_app lives in
+//! the `picloud` crate) and for the `dead_letter` reinterpretation.

+//! AES-256-GCM encryption envelope + master-key sourcing (v1.1.7).
+//!
+//! Two responsibilities:
+//!
+//!   1. [`encrypt`] / [`decrypt`] — the at-rest envelope used by per-app
+//!      `secrets`, the encrypted `inbound_secret` on email triggers, and
+//!      the realtime signing key. `Aes256Gcm` with a 96-bit (12-byte)
+//!      random nonce and a 128-bit auth tag **appended to the
+//!      ciphertext** (the RustCrypto `Aead`-trait layout — `encrypt`
+//!      returns `ciphertext || tag`, `decrypt` consumes the same). Both
+//!      the ciphertext (tag included) and the nonce are stored.
+//!
+//!   2. [`MasterKey`] — the process-wide 32-byte key, sourced once at
+//!      startup from `PICLOUD_SECRET_KEY` (base64 of exactly 32 bytes).
+//!      A deterministic in-memory dev key is allowed ONLY when the env
+//!      var is unset AND `PICLOUD_DEV_MODE=true`; otherwise an unset key
+//!      is fatal (no quiet "your secrets are unencrypted" mode).
+//!
+//! **Key rotation is out of scope for v1.1.7.** Changing
+//! `PICLOUD_SECRET_KEY` between deploys orphans every existing
+//! ciphertext (it can no longer be decrypted). v1.2+ adds key-version
+//! columns + a re-encryption pass.

+//! HMAC-signed realtime subscriber tokens (v1.1.6, design notes §5).
+//!
+//! A token is a compact, URL-safe, two-part string:
+//!
+//! ```text
+//! <base64url(payload)>.<base64url(signature)>
+//! ```
+//!
+//! where `payload` is the JSON [`TokenClaims`] and `signature` is
+//! `HMAC-SHA256(app_signing_key, base64url(payload))`. Tokens are minted
+//! by scripts via `pubsub::subscriber_token` (the minter lives in
+//! manager-core's `PubsubServiceImpl`) and verified by the SSE subscribe
+//! path (the verifier lives in manager-core's `RealtimeAuthority` impl).
+//! Both sides depend on this module so the byte-for-byte contract has a
+//! single home.
+//!
+//! There is no per-token revocation in v1.1.6 by design: HMAC bearers
+//! can't be individually revoked. Rotating an app's signing key
+//! invalidates every token for that app wholesale; short TTLs are the
+//! safety mechanism.
