docs(v1.1.9): CHANGELOG + HANDBACK.md

Browse Source 
CHANGELOG.md: new v1.1.9 entry above v1.1.8 — covers queue::* SDK,
queue:receive trigger kind, dispatcher queue arm + visibility-timeout
reclaim, invoke() + invoke_async(), retry:: SDK (including the
retry::run rename deviation), admin HTTP endpoints, dashboard 0.15.0,
Services::new + Limits + Engine + register_all signature changes,
migrations 0034/0035, F1-F5 follow-ups, env vars + SDK schema bump.
No upgrade-order constraint (pure additive).

HANDBACK.md: replaces v1.1.8's at repo root. 12 sections per the brief:
  1. Scope coverage table — 21 line items, all ✅
  2. Queue dispatcher design (claim SQL, ack/nack/dead-letter, reclaim)
  3. invoke() re-entrancy (Engine self_weak, fresh SdkCallCx, cross-app guard, depth bound)
  4. retry::* (closure passing, sleep mechanics, clamping, jitter)
  5. Dashboard notes
  6. F1-F5 implementation per follow-up
  7. Deviations beyond the brief — 7 numbered:
     D1: retry::with → retry::run (both with/call are Rhai reserved)
     D2: Trait move skipped (Engine in scope, AST cache loss deferred)
     D3: Retry columns on parent only (avoids duplicating source of truth)
     D4: Limits::trigger_depth_max mirrored from TriggerConfig
     D5: One-consumer-per-queue via pg_advisory_xact_lock
     D6: invoke() exposed globally (not invoke::*)
     D7: invoke_async runs once
  8. Verification with LITERAL output (fmt + clippy + test totals)
  9. Open questions for the reviewer (4)
  10. Latent findings (lints surfaced + fixed; no carry-forward from main)
  11. Deferred items (nothing slipped; standing v1.2+ list)
  12. Known limitations (closures across invoke, in-process only, etc.)

# PiCloud Changelog # PiCloud Changelog
## v1.1.9 — Durable Queues & Function Composition (unreleased)
Per-app durable queues + same-app function composition + caller-
controlled retries. The final v1.1.x release before the v1.2 phase
milestone. **No upgrade-order constraint** — pure additive surface,
no destructive migrations.
### Added — `queue::*` SDK (durable per-app named queues)
- **`queue::enqueue(name, message)` / `queue::enqueue(name, message, opts)`**
— write one message onto a per-app named queue. `opts` is a Map
with `delay_ms` (defer delivery until `NOW() + delay`) and
`max_attempts` (clamped to `[1, 20]`; default 3). Message is any
JSON-serializable value — Maps, Arrays, scalars, and Blobs (which
base64-encode at any depth, mirroring `pubsub::publish_durable`).
FnPtr / closures are rejected at the bridge.
- **`queue::depth(name)` / `queue::depth_pending(name)`** — read-only
inspection. `depth` is `COUNT(*)`; `depth_pending` filters to
`claim_token IS NULL AND (deliver_after IS NULL OR deliver_after <= NOW())`.
- Identity tuple is `(app_id, queue_name)`. Queue names are implicit
— no queue registry table, no separate "create queue" ceremony. A
queue exists once the first message is enqueued under that name.
- No `peek` / `dequeue` / `purge` script-side surface. Consumers are
triggers; exposing manual dequeue would force the platform to
surface visibility-timeout semantics into script-land.
- New capability `AppQueueEnqueue(AppId)` (script:write scope, editor+).
### Added — `queue:receive` trigger kind
- **Exactly one consumer per `(app_id, queue_name)`** — enforced via
`pg_advisory_xact_lock(hash(app_id || queue_name))` + a SELECT-then-
INSERT in one transaction (a partial unique index can't span the
parent's `app_id` from the detail table). The second create returns
`422 Invalid` with the message `queue 'X' already has a consumer
trigger; remove the existing one first`.
- Per-trigger `visibility_timeout_secs` (clamped `[5, 3600]`; default
via `PICLOUD_QUEUE_DEFAULT_VISIBILITY_TIMEOUT_SECS`). The dispatcher
treats this as the lease window; a handler that holds the claim
past this point loses it to the periodic reclaim task.
- Retry policy lives on the parent `triggers` row (the same
`retry_max_attempts` / `retry_backoff` / `retry_base_ms` every
other trigger kind reads); no duplication on the detail row.
- Surfaced to handler scripts as `ctx.event.queue` —
`{ queue_name, message, enqueued_at, attempt, message_id }` — plus
`ctx.event.source = "queue"` and `ctx.event.op = "receive"`.
- Trigger executes as the principal that **registered** it (matches
design notes §4 — every trigger kind does this).
### Added — Dispatcher queue arm + visibility-timeout reclaim task
- The queue table IS the outbox for queue semantics. The dispatcher
doesn't double-buffer through `outbox`; it claims directly from
`queue_messages` via the single-round-trip
`UPDATE … WHERE id = (SELECT id … FOR UPDATE SKIP LOCKED LIMIT 1)
RETURNING …`. `SKIP LOCKED` keeps concurrent dispatchers (cluster
mode v1.3+) safe.
- Per tick (every 100ms), interleaved with the existing outbox arm:
list every enabled `queue:receive` consumer and try one claim each.
Bounded by the registered-consumer count, so one busy queue can't
starve the rest.
- **Auto-ack**: handler returns successfully → `DELETE FROM queue_messages
WHERE id = $1 AND claim_token = $2`. The token in the WHERE is the
leasing guarantee.
- **Auto-nack**: handler throws → if `attempt < max_attempts`, clear
the claim and set `deliver_after = NOW() + compute_backoff(...)`;
else, write a `dead_letters` row (the existing `fan_out_dead_letter`
path then fires registered `dead_letter` triggers off it) and delete
the queue row, in one transaction.
- **Visibility-timeout reclaim**: a separate `tokio::spawn` task ticks
every `PICLOUD_QUEUE_RECLAIM_INTERVAL_MS` (default 30000) and clears
claims older than the per-queue `visibility_timeout_secs`. A crashed
consumer (or one whose handler hung past the visibility window) thus
loses its lease and the message becomes claimable again.
### Added — `invoke()` + `invoke_async()` (same-app function composition)
- **`invoke(target, args)`** — sync, returns the callee's response
body as a Rhai Dynamic. `target` is a string (path → route trie,
UUID → `ScriptId`, else → `(app_id, name)` lookup). Same engine
instance and `Services` are reused; only the per-call `SdkCallCx`
changes (callee gets `trigger_depth + 1` and a fresh `execution_id`,
inherits the caller's principal and `root_execution_id`).
- **`invoke_async(target, args)`** — fire-and-forget. Writes an
`OutboxSourceKind::Invoke` row the dispatcher fires once (no retry
loop — callers who want retries wrap in `retry::run`). Returns the
new `ExecutionId` as a string for caller tracking.
- **Cross-app invokes are rejected** at the `InvokeService::resolve`
layer with `InvokeError::CrossApp` ("invoke: target script belongs
to a different app"). v1.1.x maintains strict isolation; cross-app
sharing arrives in v1.3+.
- **Depth-bound**: `cx.trigger_depth + 1 > limits.trigger_depth_max`
throws "invoke: depth limit exceeded (max N)" — shared with the
trigger fan-out cap so a misbehaving recursive script can't blow
the stack.
- FnPtr / closures in `args` are rejected (closures don't survive
re-entry into a fresh `SdkCallCx`).
### Added — `retry::*` SDK (caller-controlled retry)
- **`retry::policy(opts)`** — constructs a `Policy` value (custom Rhai
type). Validates + clamps: `max_attempts ∈ [1, 20]`,
`base_ms ∈ [1, 60_000]`, `jitter_pct ∈ [0, 100]`,
`backoff ∈ {"exponential" | "linear" | "constant"}`.
- **`retry::run(policy, closure)`** — calls `closure()`; on throw,
sleeps per the policy and re-invokes; after `max_attempts`
exhausted, throws the last error. Sleeps via `tokio::time::sleep`
through `TokioHandle::block_on` — the bridge is already inside the
caller's `spawn_blocking` thread.
- **`retry::on_codes(policy, codes_array)`** — returns a new policy
with an error-string filter. When non-empty, only throws containing
one of the codes retry; others surface immediately.
- **NOTE on the brief deviation**: the brief asked for `retry::with`,
but both `with` AND `call` are Rhai reserved keywords (rejected at
the parser, before registration could matter). Shipped as
`retry::run(policy, closure)` instead. Documented in HANDBACK §7.
### Added — Admin HTTP endpoints
- `POST /api/v1/admin/apps/{id}/triggers/queue` — create a
`queue:receive` trigger. Body:
`{ script_id, queue_name, visibility_timeout_secs?, dispatch_mode?,
retry_max_attempts?, retry_backoff?, retry_base_ms? }`.
Capability: `AppManageTriggers`.
- `GET /api/v1/admin/apps/{id}/queues` — list every distinct queue
name in the app with `(total, pending, claimed)` counts.
Capability: `AppLogRead`.
- `GET /api/v1/admin/apps/{id}/queues/{queue_name}` — drill-down:
stats + registered consumer trigger (if any). Capability:
`AppLogRead`.
- No mutating queue endpoints (purge / requeue / delete-message stays
at v1.2).
### Added — Dashboard (v0.15.0)
- New `/apps/{slug}/queues` read-only list view (queue name + counts +
drilldown link) and `/apps/{slug}/queues/{name}` drill-down (depth +
registered consumer + visibility timeout + last_fired_at).
- "Queues" link added to the app-level nav between Files and Dead
letters.
- Triggers tab gains a "Queue:receive trigger (v1.1.9)" form alongside
cron / pubsub / email. Trigger list renders queue triggers with the
queue name + visibility timeout + last_fired_at.
- TypeScript types: `TriggerKind` gains `'queue'`; `TriggerDetails`
gains the `Queue` variant. `CreateQueueTriggerInput`,
`QueueSummary`, `QueueConsumer`, `QueueDetail` exported.
### Changed
- `Services::new` signature gains `queue: Arc<dyn QueueService>` and
`invoke: Arc<dyn InvokeService>` positionally after `users` (mirrors
v1.1.8's positional append of `users`). `with_noop_services` updated.
- `Limits` (`crates/executor-core/src/sandbox.rs`) gains
`trigger_depth_max: u32` (default 8). The picloud binary syncs it
from `TriggerConfig::from_env().max_trigger_depth` so the
dispatcher's trigger-depth cap and the invoke depth-bound stay
aligned (env var: `PICLOUD_MAX_TRIGGER_DEPTH`).
- `Engine` gains `set_self_weak(Weak<Engine>)` + `self_arc()`. The
picloud binary calls `engine.set_self_weak(Arc::downgrade(&engine))`
right after construction so the invoke bridge can re-enter the
engine synchronously. `Weak` so the Arc-cycle stays loose.
- `register_all` gains two parameters: `limits: Limits` and
`self_engine: Option<Arc<Engine>>`. The invoke bridge surfaces a
clear error if `self_engine` is `None` (only in harnesses that don't
wire it).
- `OutboxSourceKind` gains `Invoke`; `TriggerKind` gains `Queue`;
`TriggerDetails` gains the `Queue` variant; `TriggerEvent` gains the
`Queue` variant with `source = "queue"` discriminant.
- `ScriptRepository` gains `get_by_name(app_id, name)` for the
`invoke()` name resolution path.
- SDK schema 1.9 → 1.10.
### Migrations
- `0034_queue_messages.sql` — the `queue_messages` table with three
indexes: a partial `(app_id, queue_name, enqueued_at) WHERE
claim_token IS NULL` for the dispatch hot path, a `(app_id,
queue_name)` for the depth queries, and a partial `(claimed_at)
WHERE claim_token IS NOT NULL` for the reclaim scan.
- `0035_queue_triggers.sql` — widens `triggers.kind` to admit
`'queue'`, widens `outbox.source_kind` to admit `'invoke'`, adds the
`queue_trigger_details` table.
### F1–F5 follow-ups (carry-forward from v1.1.8)
- **F1 — integration test density**: four new DB-gated test binaries
(`crates/picloud/tests/queue_e2e.rs` ×4, `…/invoke_e2e.rs` ×4,
`…/retry_e2e.rs` ×3, `crates/manager-core/tests/migration_queue_messages.rs`
×4) + 50+ net new inline unit tests. All skip cleanly when
`DATABASE_URL` is unset; all pass against the docker-compose
postgres on `localhost:15432`.
- **F2 — schema snapshot re-blessed** via
`BLESS=1 cargo test -p picloud-manager-core --test schema_snapshot
-- --include-ignored`. Delta matches the plan exactly (no unrelated
drift).
- **F3 — fmt + clippy attestation as literal output**: see HANDBACK §8.
- **F4 — `TIMING_FLAT_DUMMY_HASH` dedup**: inline copy in
`crates/manager-core/src/auth_api.rs::login` now references the
shared `crate::auth::TIMING_FLAT_DUMMY_HASH` const. `grep -rn` for
the PHC literal returns exactly one hit.
- **F5 — clippy without cold cache**: incremental cache used; HANDBACK
§8 notes the explicit choice.
### Notes
- New env vars:
- `PICLOUD_QUEUE_RECLAIM_INTERVAL_MS` (default 30000) — visibility-
timeout reclaim cadence.
- `PICLOUD_QUEUE_DEFAULT_VISIBILITY_TIMEOUT_SECS` (default 30) —
visibility timeout fallback when the trigger create request omits
one. Per-trigger column overrides this.
- SDK schema bumped to 1.10.
- `@picloud/client` unchanged — no client-library work this release.

Branch: `feat/v1.1.8-user-management` Branch: `feat/v1.1.9-queues-invoke` (cut from `main` at `b9e002a`).
Base commit: `5cbb6ca` (v1.1.7 head). Workspace: `picloud@1.1.9`. Dashboard: `0.15.0`. SDK schema: `1.10`.
Tip: see `git log --oneline main..HEAD`. **Pure additive — no upgrade-order constraint.**
The reviewer should read **§7 (deviations)** first — it lists every
judgment call beyond a strict literal reading of the brief.

**Deferrable piece (invitations) NOT deferred.** Invitations shipped as ## 2. Queue dispatcher design notes
specified — script-side `users::invite` + `users::accept_invite` + admin
HTTP + admin invitations sub-tab.
--- **The queue table IS the outbox for queue semantics.** No
double-buffering through `outbox.source_kind = 'queue'`. The
dispatcher's `tick_queue_arm` lists active consumers
(`triggers.list_active_queue_consumers()` — joins `triggers` +
`queue_trigger_details` for enabled `kind = 'queue'` rows) and runs
one atomic claim per `(app_id, queue_name)` per tick.
## 2. Encryption / sessions design notes Claim shape (single round trip):
- **Session tokens are SHA-256 hashes** of a 32-byte URL-safe-base64 ```sql
raw token. Mirror of `admin_sessions`. The raw appears once in the UPDATE queue_messages
login / accept_invite response; only the hash hits storage. No SET claim_token = $3, claimed_at = NOW(), attempt = attempt + 1
Argon2 on the session token — it is high-entropy and one-shot per WHERE id = (
session, so the fast SHA-256 lookup is right. Argon2id is reserved SELECT id FROM queue_messages
for password verification. WHERE app_id = $1 AND queue_name = $2
- **Sliding TTL** is bumped on every successful `verify` (and on AND claim_token IS NULL
`verify_session_for_realtime` for the F3 path). The new AND (deliver_after IS NULL OR deliver_after <= NOW())
`expires_at` is `min(now + session_ttl, absolute_expires_at)`; the ORDER BY enqueued_at
absolute cap is set at creation and never moves. Beyond it, the FOR UPDATE SKIP LOCKED
session is dead regardless of recent activity. LIMIT 1
- **Revocation is explicit** (`revoked_at TIMESTAMPTZ`). Three sources )
set it: logout (`users::logout`), admin revoke-sessions endpoint, RETURNING id, app_id, queue_name, payload, enqueued_at, attempt, max_attempts
and password reset (revokes every active session for the user). The
lookup query rejects revoked rows immediately so revocation takes
effect before the weekly GC sweep runs.
- **One-shot tokens** (verification, password reset, invitations) all
store SHA-256 of the raw 32-byte token. The consume path is an
atomic `UPDATE WHERE consumed_at IS NULL` (or `accepted_at IS NULL`
for invitations). rowcount=1 means valid-and-now-used; rowcount=0
means missing/already-consumed/expired/wrong-app. No race window.
- **Cross-app isolation** is enforced at every read. The session
lookup by token hash returns `(app_id, user_id, expires_at,
abs_cap)`; the service checks `app_id == cx.app_id` before honoring
the session. Even though the token hash is high-entropy and unlikely
to collide across apps, the defense-in-depth check is cheap.
- **At-rest encryption is NOT used for session/token rows** — the
hashes are one-way already. v1.1.7's at-rest encryption applies
only to the realtime HMAC signing key (which IS recoverable from
its storage form, so it needs sealing).
---
## 3. Users SDK notes
- **Argon2id with the existing `auth::hash_password` /
`verify_password` helpers.** Default Argon2 parameters
(m=19456, t=2, p=1). The brief says "reuse the existing dep; do
not introduce bcrypt or PBKDF2" — followed verbatim.
- **Timing-flat login** — on email miss, the service runs
`verify_password(TIMING_FLAT_DUMMY_HASH, password)` and discards
the result. The dummy hash is a real Argon2id PHC string exported
from `manager-core::auth` (the same hash the admin auth path uses,
factored into a shared constant). Same code path either way; same
wall clock either way.
- **The `validate_email` path is also timing-flat** — an unparseable
email shape runs the dummy verify before returning `Ok(None)`, so
the bad-shape and bad-email-real-user paths share timing too.
- **`users::create` on duplicate email** returns
`UsersError::DuplicateEmail` — distinguishable in script-land (a
script can `try`/`catch` and switch on the message prefix
`users::`). The database's `(app_id, lower(email))` unique
constraint enforces it.
- **`users::list` cursor** is the `created_at` of the last row from
the previous page. Sort is `ORDER BY created_at DESC, id DESC`.
Limit defaults to 50, capped at 500.
- **Event emission** — every mutation emits a `ServiceEvent { source:
"users", op, key: Some(user_id) }`. v1.1.8 does not register any
triggers on these events; the wiring is there for the future
triggers framework to extend without a service-layer change.
- **`AppUser.roles: Vec<String>` is populated via
`AppUserRoleRepo::list_for_user`** on every getter (one extra
query per user). For lists of N users this is N+1 — acceptable at
v1.1.x scale; if it becomes a problem v1.2 can batch via a single
JOIN.
---
## 4. Email-tied flows
- **Disabled-mode behavior** — `EmailError::NotConfigured` propagates
as `UsersError::EmailNotConfigured` from
`send_verification_email`, `request_password_reset`, `invite`,
and `admin_create_invitation`. Scripts already handling the
v1.1.7 email-disabled mode get the same observable via a
parallel error code; no new branches needed.
- **Template control** — the script (or admin) provides
`EmailTemplateOpts { link_base, from, subject, body_template }`.
Template substitution is a single replace of `{link}` with
`link_base?token=<raw>` (or `&token=` if link_base has a `?`).
No HTML escaping happens server-side — scripts that want HTML
email use their own email_send path; verification/reset/invite
emails are plain text only (matches the brief).
- **`from` is required in `EmailTemplateOpts`** — see §7 for the
deviation note.
- **`request_password_reset` has zero existence-leak signal**.
Script-side return is unconditionally `Ok(())` whether or not the
email matched. If found, an email goes out; if not, no email goes
out; the script can't tell the difference. The only observable
that DOES leak is `EmailNotConfigured` — that's the operator's
known state, not a per-user signal.
- **`request_password_reset` swallows non-NotConfigured email
errors** (logs server-side, returns Ok(()) to script). A surfaced
"InvalidAddress" error would otherwise reveal "this email parsed
as invalid" — a probing signal.
- **`invite` non-NotConfigured email errors are NOT swallowed for
the SDK path** but the invitation row is left in place — admin
can retry delivery out-of-band. The token is valid until accepted
or expired.
- **`accept_invite` returns `()` if the user already exists** (sign-up
beat acceptance). The invitation is consumed; the user logs in
normally with their existing password. Documented.
---
## 5. Per-app roles
**v1.1.8 ships string-tagged roles only.** No role registry, no
hierarchy, no permission matrix. The script app decides what
`"admin"` / `"editor"` / `"viewer"` mean — `users::has_role` returns
a bool and that's the whole API contract. Role permission matrices
are explicitly a v1.2 design item per the brief.
The `AppUser` record returned by every `users::*` getter carries a
`roles: [...]` field populated by a separate query against
`app_user_roles` (composite PK so add is idempotent via `ON CONFLICT
DO NOTHING`). The dashboard's Users tab renders roles as chips on
the list and shows them read-only on the edit modal (with a hint
that role mutation goes through the SDK).
Pre-staged roles on invitations are applied atomically with user
creation in `accept_invite`. Malformed role strings are skipped with
a warn log rather than aborting the whole accept — the invitation
was the admin's promise, and we honor as much of it as we can.
---
## 6. F1 / F2 / F3 implementation notes
### F1 — drop plaintext realtime_signing_key column
- Migration 0032 has a guard `DO $$ ... RAISE EXCEPTION ... $$` that
refuses to apply if any row still has `realtime_signing_key IS
NOT NULL AND realtime_signing_key_encrypted IS NULL`. This forces
operators who skipped v1.1.7 to apply it first — the v1.1.7
startup task is the only thing that knows how to encrypt the
existing plaintext.
- The brief mentioned dropping
`realtime_signing_key_nonce_LEGACY_IF_EXISTS` but recon of
migration 0025 confirmed only `realtime_signing_key` (plaintext)
and the encrypted+nonce pair exist — no legacy nonce column to
drop. Documented in §7.
- The v1.1.7 `migrate_plaintext_keys` startup task and its callsite
in `build_app` are deleted. The read path consults only the
encrypted columns.
- `app_secrets_repo.rs` tests dropped from 5 to 3 (the plaintext
fallback test is gone with the column). The remaining tests cover
encrypted-only happy path, missing-columns None, and
wrong-master-key Crypto error.
### F2 — clippy `--all-targets` discipline
**Deviation from the brief.** The brief specifies `cargo clean`
before the clippy attestation. I skipped the clean step because a
prior `cargo test --workspace` froze the host (the user explicitly
asked for lighter subsequent builds). The incremental cache was
hot for every workspace crate when clippy ran. The full output
included `Checking <crate> ... (test)` lines for all integration
test binaries — visually confirmed.
The v1.1.8-introduced lints fixed:
- 12x `map_unwrap_or` in `executor-core/sdk/users.rs` (Option →
Dynamic conversion shape) — rewrote as `map_or`.
- 1x doc-list-without-indentation in
`app_user_password_reset_repo` — rewrap.
- 1x `cast_possible_wrap` (usize → i64) in `app_user_repo.rs` list
— `i64::try_from(...).unwrap_or(i64::MAX)`.
- 2x `map_unwrap_or` in `users_service.rs` env helpers.
- 1x `match_single_pattern` in `users_service.rs` login —
let-else rewrite with the dummy-Argon2 side-effect in the
diverging branch.
Final clippy run command + outcome:
``` ```
cargo clippy --workspace --all-targets --all-features -- -D warnings
... Checking ... (test) for every workspace crate ... `SKIP LOCKED` keeps concurrent dispatchers (cluster mode v1.3+) safe.
Finished `dev` profile [unoptimized + debuginfo] target(s) in 14.40s The `claim_token` (fresh `Uuid::new_v4()` per claim) is the lease
guarantee: ack and nack both filter `WHERE id = $1 AND claim_token =
$2`, so a stale dispatcher whose visibility-timeout expired can't
accidentally delete or re-defer a message that's been re-claimed.
**Ack** (handler returned successfully):
`DELETE FROM queue_messages WHERE id = $1 AND claim_token = $2`.
**Nack** (handler threw, `attempt < max_attempts`):
`UPDATE … SET claim_token = NULL, claimed_at = NULL, deliver_after =
NOW() + retry_delay`. Backoff delay computed via the existing
`compute_backoff(attempt, backoff_shape, base_ms, jitter_pct)` —
shared with the outbox arm so retry behavior is identical across
trigger kinds.
**Dead-letter** (handler threw, `attempt >= max_attempts`): single
transaction — `INSERT INTO dead_letters` with `source = "queue"`,
`op = "receive"`, the original payload wrapped in a shape mirroring
`TriggerEvent::Queue` (so the existing `fan_out_dead_letter` path on
the outbox arm can fire registered `dead_letter` triggers off the new
row without any special-casing), then `DELETE FROM queue_messages`.
**Visibility-timeout reclaim**: separate `tokio::spawn` task, ticks
every `PICLOUD_QUEUE_RECLAIM_INTERVAL_MS` (default 30 000 ms). UPDATE
joins `queue_messages` + `triggers` + `queue_trigger_details` and
clears claims older than the per-queue `visibility_timeout_secs`. A
crashed consumer thus loses its lease and the message becomes
claimable again. **Verified** by `queue_e2e::queue_visibility_timeout_reclaim`
(inserts a row with `claimed_at = NOW() - 60s`, `visibility_timeout =
5s`; polls until either the dispatcher re-claims or the claim
clears).
## 3. `invoke()` re-entrancy notes
**Engine sharing** via `Engine::self_weak: OnceLock<Weak<Engine>>`.
The picloud binary:
```rust
let engine = Arc::new(Engine::new(engine_limits, services));
engine.set_self_weak(Arc::downgrade(&engine));
``` ```
Zero warnings, zero errors.
### F3 — realtime auth_mode = 'session' `Engine::execute_ast` reads `self.self_arc()` (which upgrades the
`Weak`) and threads `Option<Arc<Engine>>` through
`sdk::register_all(...)` to the invoke bridge.
- Migration 0033 widens the `topics_auth_mode_check` CHECK **`Weak` is the right choice** — strong would make the Engine Arc
constraint to allow `('public', 'token', 'session')`. cycle itself, leaking on drop. Cycle stays broken; the invoke bridge
- `TopicAuthMode` enum gains `Session`; `as_str` + `from_db` just gets `None` if the engine has been dropped (which only happens
updated. on shutdown).
- `RealtimeAuthorityImpl::new` takes a 3rd arg `Arc<dyn
UsersService>`. Constructor signature changed; picloud binary
reshuffles construction order so `users` is built before
`realtime_authority`.
- `authorize_subscribe`'s Session arm calls
`users.verify_session_for_realtime(app_id, token)` — no
SdkCallCx is needed (the realtime authority is not in a script
execution). The service bumps the sliding TTL on success. The
arm also defense-in-depth-checks `user.app_id == app_id` even
though the service already enforces cross-app isolation.
- Token extraction (`Authorization: Bearer` or `?token=`) is
unchanged from the Token branch; the SSE handler passes whatever
it found to `authorize_subscribe(app_id, topic, token)`.
- Dashboard Topics radio gains `session` as a third option (both
in the create and edit forms).
- 4 new unit tests on `RealtimeAuthorityImpl`: valid session
allows, missing token Unauthorized, wrong token Unauthorized,
cross-app token Unauthorized. All 12 realtime_authority tests
pass.
--- **Re-entry path** (inside `invoke.rs::invoke_blocking`):
1. Resolve via `InvokeService::resolve(&cx, target)` — service-layer
cross-app check returns `InvokeError::CrossApp` if `resolved.app_id
!= cx.app_id`.
2. Depth check **before** resolve — `cx.trigger_depth + 1 >
limits.trigger_depth_max` throws immediately (no wasted DB
round-trip).
3. Build a fresh `ExecRequest` carrying:
- new `execution_id`
- `root_execution_id` inherited from caller's `cx.root_execution_id`
- `trigger_depth = cx.trigger_depth + 1`
- `request_id` inherited (same logical request)
- principal inherited (same-app invoke is a function call, not a
re-auth boundary)
- `body = args_json`
4. Call `self_engine.execute(&resolved.source, req)` — synchronous,
on the SAME `spawn_blocking` thread. No nested `spawn_blocking`
(would deadlock the blocking pool under load) and no gate
re-admission (the outer execution already holds a permit).
5. Return `json_to_dynamic(resp.body)` — the callee's response body
becomes the caller's invoke return value. Status code + headers
are dropped (the function-call mental model is "return value", not
"HTTP response").
**Cross-app rejection point**: verified at three layers — repo
returns the script row, service compares `resolved.app_id` to
`cx.app_id`, and the dispatcher's `build_invoke_request` re-checks
when firing an `invoke_async` outbox row (defense in depth — the
service already enforced same-app at enqueue time, but a hand-edited
row should still be rejected).
**Depth-bound** integration tested by `invoke_e2e::invoke_depth_limit_exceeds_cleanly`
— recursive script propagates the throw all the way up; outer
caller's `try/catch` surfaces "invoke: depth limit exceeded (max 8)".
## 4. `retry::*` notes
**Closure passing** via Rhai's `FnPtr`. `retry::run(policy, fn_ptr)`
is registered with `NativeCallContext` so the bridge can call
`fn_ptr.call_within_context(ctx, ())` in a loop. The closure shares
the caller's engine + cx — if the closure itself calls `invoke()`,
the inner call goes through the invoke bridge (fresh cx with
`trigger_depth + 1`), retry doesn't see or interfere with that.
**Sleep mechanics**: `tokio::time::sleep(delay)` via
`TokioHandle::block_on`. We're already inside the caller's
`spawn_blocking` thread, so blocking the thread on a tokio sleep is
fine — the runtime's worker pool isn't being held.
**Policy clamping** at construction (`retry::policy(opts)`):
- `max_attempts ∈ [1, 20]` — saturating clamp
- `base_ms ∈ [1, 60_000]` — saturating clamp
- `jitter_pct ∈ [0, 100]` — saturating clamp
- `backoff ∈ {"exponential" | "linear" | "constant"}` — bogus values
surface a clear error
- `on_codes` defaults to empty (retry every throw); when non-empty,
filters by substring match
**Jitter**: deterministic via `DefaultHasher` over `(span, raw)` —
random distribution doesn't matter for retry; bounded ± is all we
need. Avoids pulling `rand` into the hot path.
## 5. Dashboard notes
- New routes: `/apps/[slug]/queues` (list) and
`/apps/[slug]/queues/[name]` (drill-down). Both use Svelte 5 runes
(`$state`, `$derived`, `$effect`) — matches the existing app
detail page's idioms.
- Triggers tab gains a "Queue:receive trigger (v1.1.9)" form below the
Email form. Same `submitCreate*` pattern as the other forms; clears
state on success and re-loads the trigger list.
- App-level nav gains a "Queues" link between Files and Dead letters,
guarded by `canAdmin` (same gate as the other operational tabs).
- TypeScript types: `TriggerKind` admits `'queue'`, `TriggerDetails`
union admits the `{ kind: 'queue', queue_name, visibility_timeout_secs,
last_fired_at }` shape. `CreateQueueTriggerInput`, `QueueSummary`,
`QueueConsumer`, `QueueDetail` exported alongside.
- `npm run check`: my changes typecheck clean. (The 149 pre-existing
errors are all in `tests/e2e/**/*.spec.ts` about `@playwright/test`
not being installed — unchanged from main.)
- `dashboard/package.json` bumped to `0.15.0`.
## 6. F1–F5 implementation notes
**F1 — integration test density.** Four new DB-gated test binaries
(all skip cleanly when `DATABASE_URL` is unset, mirroring the
existing `dispatcher_e2e.rs` pattern):
- `crates/picloud/tests/queue_e2e.rs` (4 tests, 33s runtime):
- `queue_receive_acks_on_success`
- `queue_receive_dead_letters_after_max_attempts`
- `queue_one_consumer_per_queue_rejected`
- `queue_visibility_timeout_reclaim`
- `crates/picloud/tests/invoke_e2e.rs` (4 tests, 2s):
- `invoke_by_name_same_app_returns_value`
- `invoke_cross_app_rejects`
- `invoke_depth_limit_exceeds_cleanly`
- `invoke_async_enqueues_outbox_row`
- `crates/picloud/tests/retry_e2e.rs` (3 tests, 2.5s):
- `retry_run_eventually_succeeds_inside_http_handler`
- `retry_run_surfaces_last_error_after_max_attempts`
- `retry_on_codes_filters_unmatched_errors`
- `crates/manager-core/tests/migration_queue_messages.rs` (4 tests):
- `queue_messages_table_exists_with_expected_columns`
- `queue_trigger_details_table_exists`
- `queue_widens_trigger_kind_and_outbox_source_kind`
- `queue_messages_dispatch_index_is_partial`
Plus 50+ net new inline unit tests across the affected crates. All
pass against the docker-compose postgres on `localhost:15432`. See
§8 for the literal `cargo test` output.
**F2 — schema snapshot `BLESS=1` part of the gate.** Re-blessed via:
```sh
DATABASE_URL=postgres://picloud:picloud@localhost:15432/picloud \
PICLOUD_ADMIN_USERNAME=dev PICLOUD_ADMIN_PASSWORD=dev \
BLESS=1 cargo test -p picloud-manager-core --test schema_snapshot \
-- --include-ignored
```
Delta committed in `chore(v1.1.9): re-bless schema snapshot (0034 + 0035 delta)`.
Matches the plan exactly: two new tables, three new partial indexes,
widened `triggers.kind` + `outbox.source_kind` CHECKs, no unrelated
drift.
**F3 — fmt + clippy attestation as literal output.** See §8.
**F4 — `TIMING_FLAT_DUMMY_HASH` dedup.** `crates/manager-core/src/auth_api.rs::login`
now reads `crate::auth::TIMING_FLAT_DUMMY_HASH.to_string()` on the
bad-email branch. Verification:
```sh
$ grep -rn 'argon2id\$v=19\$m=19456,t=2,p=1\$dGltaW5n' crates/
crates/manager-core/src/auth.rs:36: "$argon2id$v=19$m=19456,t=2,p=1$dGltaW5nLWZsYXR0ZW4$Ux6dgPqgX1Mhg5fRgIeKZF3MWdYqJplKEz/cKLcSdks";
```
Exactly one hit — the const declaration in `auth.rs`.
**F5 — clippy cold-cache environmental constraint.** Used the
incremental cache (no `cargo clean`). Verified by checking the
`Checking <crate>` lines for test crates appear in the clippy output.
CI will do the cold-cache attestation on its dedicated runner.
## 7. Decisions beyond the brief / deviations flagged ## 7. Decisions beyond the brief / deviations flagged
Read first. **D1 — `retry::with` → `retry::run` (script-side name).** The brief
specified `retry::with(policy, closure)`. Both `with` AND `call` are
Rhai reserved keywords — rejected at the parser, before any
registration would matter (`'with' is a reserved keyword (line N, position M)`).
Shipped as `retry::run(policy, closure)`. Documented in the docstring,
the SDK_VERSION 1.10 changelog comment, and the dashboard form copy.
1. **`EmailTemplateOpts.from` is required.** The brief's example **D2 — Trait move skipped (was plan §5).** The plan called for moving

audit log.
**Impact on script authors**: scripts must include
`from: "..."` in the template map. A no-op change for any
script that already calls `email::send` (`from` is required
there too).

Migration 0032 drops only `realtime_signing_key`. `TriggerConfig::from_env().max_trigger_depth` in the picloud binary,
so `PICLOUD_MAX_TRIGGER_DEPTH` governs both the dispatcher's fan-out
cap and the invoke depth-bound. Avoids the depth check having to
reach into trigger config inside the engine.
4. **DELETE `/users/{user_id}` is gated `AppUsersWrite`, not **D5 — One-consumer-per-queue via advisory lock (was plan §1).** A
`AppUsersAdmin`.** The brief specifies: partial unique index across `triggers.app_id` and
- `users::delete` (SDK) → `AppUsersWrite` `queue_trigger_details.queue_name` is not expressible (partial
- `DELETE /users/{user_id}` (admin) → `AppUsersAdmin` indexes can't reference foreign columns). Chose API-layer
These would diverge. The service's `delete` checks enforcement: `pg_advisory_xact_lock(hashtext(app_id || queue_name))`
`AppUsersWrite`; if I added an additional `AppUsersAdmin` + SELECT-then-INSERT in one transaction. The advisory lock is

left the HTTP handler going through the service unchanged,
which gates on `AppUsersWrite`. **The dashboard delete button
still functions only for app_admin+ in practice** (the role
chain), so the brief's intent is preserved. If the reviewer
wants a literal double-check they can wrap it.
5. **`cargo clean` skipped on F2 attestation.** See §6 F2 above. **D6 — `invoke()` exposed globally (not `invoke::*`).** The brief
Documented separately because the brief was emphatic about the spelled `invoke(target, args)` as a top-level helper, not under a
clean step. `::` namespace. Registered via `engine.register_global_module(...)`
so scripts write `invoke("worker")` rather than `invoke::call("worker")`.
6. **Schema snapshot NOT re-blessed in this branch.** The **D7 — `invoke_async` runs once.** The brief specifically says
`schema_snapshot` test is `DATABASE_URL`-gated; without a `invoke_async` runs once; callers wrap in `retry::with` if they want

golden file. The reviewer's CI (or a `BLESS=1` run on a DB ResolvedTrigger inside `dispatcher.rs::build_invoke_request`, which
host) will produce the diff. The brief said this would happen short-circuits the existing retry loop and goes straight to dead-letter
— flagging that `tests/expected_schema.txt` will need to be on failure (so misfires are observable).
updated alongside the reviewer's audit, not by me. Per v1.1.7
commit `a7d3dad` the pattern is `BLESS=1 DATABASE_URL=... cargo
test -p picloud-manager-core --test schema_snapshot --
--include-ignored`.
7. **Test density target NOT met from new test binaries.** The ## 8. Verification (literal output)
brief asked for ~5-10 new test binaries and ~50-100 new tests.
v1.1.8 ships:
- New unit tests in existing crates (authz: 2 cases; realtime
authority: 4 cases; app_secrets_repo: net -2 cases). Total
new unit tests: 6.
- **Zero new integration test binaries.** The brief's
enumerated list (`app_user_repo`, `app_user_session_repo`,
`users_service`, `users_email_flows`, `users_admin_api`,
`users_realtime_session`, `migration_0032_drop_plaintext`,
`users_sdk`, `users_cross_app_isolation`) would all be
DB-gated.
- I prioritized correctness of the service layer (compile +
lint + unit-test the new code paths) over the integration
test density target because the host froze on `cargo test
--workspace` and the user asked for lighter subsequent runs.
- **The reviewer will need to add integration tests on a DB
host** OR explicitly accept this as a known gap. See §9 +
§10.
8. **Admin-mediated invitation path is its own trait method
(`admin_create_invitation`).** The brief listed
`list_invitations` and `revoke_invitation` as admin-mediated
(taking `&Principal`) but expected `invite` to serve both the
SDK and admin paths. `invite` takes `&SdkCallCx`; the admin
layer doesn't have one. Synthesizing a cx with a real principal
was an option but the cleaner separation is a dedicated trait
method. Documented.
9. **Internal email sends synthesize an SdkCallCx with
`principal: None`** for `send_verification_email`,
`request_password_reset`, and the SDK-side `invite`. The
`users::*` gate has already fired; the internal email hop
isn't the user's direct invocation.
`admin_create_invitation` is different — it uses the admin's
real principal so the email-service `AppEmailSend` gate fires
against the admin (whose dashboard action this is).
10. **No backward-compat shim for the `Services::new`
signature.** The new `users` arg is positional; the 10
executor-core integration test binaries needed updating. Not
silently backward-compatible. Reviewer-visible.

What I actually ran on this host (and why): **F5 note**: ran clippy WITHOUT a `cargo clean` first (incremental
cache used). The `Checking …` lines for test crates appear in the
unfiltered output. CI will do the cold-cache attestation on its
dedicated runner.
- **`cargo fmt --all -- --check`** — green. **Workspace lib unit smoke** (per-crate, no `DATABASE_URL`):
- **`cargo clippy --workspace --all-targets --all-features --
-D warnings`** — green. Run incrementally (no preceding `cargo
clean`) per §6 F2. Test binaries appeared in the Checking
output.
- **`cargo test`**: did NOT run a full `--workspace` pass. The
user reported the prior workspace test invocation froze the
host. I ran targeted unit tests instead:
```
cargo test -p picloud-manager-core --lib authz:: -- --test-threads=1
→ 16 passed; 0 failed (includes 2 new app_users tests)
cargo test -p picloud-manager-core --lib realtime_authority::tests -- --test-threads=1 ```
→ 12 passed; 0 failed (8 pre-existing + 4 new F3 cases) shared: 34 passed
executor-core: 218 passed (74 lib + 144 across the ten tests/sdk_*.rs binaries)
manager-core: 311 passed (306 lib + 4 migration + 1 schema_snapshot)
orchestrator-core: 74 passed
```
cargo test -p picloud-manager-core --lib app_secrets_repo:: -- --test-threads=1 **DB-gated E2E** (against `docker compose up -d postgres`,

was dropped with the column)
```
- **Dashboard `npm run check`** — 150 errors, ALL in pre-existing
`tests/e2e/*` files (missing `@playwright/test` install). Zero
errors in `src/`.
**Pass-count attestation (qualified):** I cannot produce the ```
awk-sourced workspace total because I did not run the full picloud queue_e2e: 4 passed in 33.21s
workspace test pass. Reviewer with more memory should run that picloud invoke_e2e: 4 passed in 3.38s
and update §8 with the literal output. picloud retry_e2e: 3 passed in 1.65s
picloud dispatcher_e2e: 9 passed in 32.70s
picloud api: 8 passed in 3.85s
picloud authz: 4 passed in 2.31s
picloud email_inbound: 4 passed (existing)
manager-core migration_queue_messages: 4 passed in 0.12s
manager-core schema_snapshot: 1 passed in 0.28s
```
--- All pass. Total across all binaries (lib + integration + DB-gated):
~660 tests.
**F4 verification**:
```sh

```
Exactly one hit.
**Dashboard typecheck**:
```sh
$ cd dashboard && npx svelte-check --tsconfig ./tsconfig.json 2>&1 | grep -E "queues/|api\.ts" | head -10
1780778502345 ERROR "tests/e2e/fixtures/api.ts" 1:49 "Cannot find module '@playwright/test' or its corresponding type declarations."
```
That's a pre-existing `tests/e2e/` Playwright type error, unchanged
from main. My queue-related code typechecks clean.

Standing deferred (v1.2+ per brief): **Standing v1.2+ deferred list** (no change from the brief):
- OAuth / OIDC / 2FA / TOTP / WebAuthn / SSO / SAML
- Password policy beyond 8-char minimum
- User-to-user messaging
- Cross-app user sharing (v1.3+)
- Per-role permission matrices / hierarchy / role registry (v1.2)
--- - Cross-app `invoke()`
- Queue priorities
- Cron-style scheduled enqueues
- Queue purge / delete / requeue admin UI
- Cluster-mode `invoke()` (orchestrator → executor RPC)
- Distributed retry / sagas / compensations
- Closures captured across `invoke()` boundaries (rejected at the
bridge — see §12)
- `ctx.trigger_depth` surface in the Rhai `ctx` map (v1.2 follow-up)
- AST cache reuse across `invoke()` calls (deferred D2 optimization)
- `invoke()` method-aware route resolution (currently POST→GET fallback)
