627996cde7 fix(project-tool): address independent review of init + staleness
Remediation after an independent review of the two feature commits.

pic init:
- Fix the headline `pic init --dir <new-dir>` flow: slug derivation used
  `canonicalize()`, which fails on a not-yet-created directory → empty
  slug → bail. Derive from the path's own final component first, falling
  back to canonicalize only for `.`. Add a test that exercised the gap
  (the existing tests all passed an explicit slug).
- `ensure_gitignored` no longer overwrites an existing-but-unreadable
  `.gitignore` (only a genuinely-absent file is treated as empty).

Bound-plan staleness:
- Token trigger coverage now mirrors the diff exactly via
  `current_trigger_identity`: dead-letter triggers (which the diff
  ignores and the manifest can't represent) and the currently-inert
  `enabled` flag are no longer hashed, so an out-of-band dead-letter
  change can't force a spurious `--force`. Add a test.
- Correct two overclaiming comments: the check shares the diff's
  pool-read apply-vs-interactive-write window (it is not tx-scoped), and
  the token deliberately mirrors the diff's inputs.
- `.picloud/` self-ignores via a `*` `.gitignore` written alongside the
  plan token, so projects created with `pic pull`/`plan` (not just
  `init`) keep it out of git.
- `clear_plan` is now app-scoped: it won't discard a token recorded for a
  different app sharing the directory.

Tested: manager-core lib 364 + cli bins 31 + 14 project-tool journeys
green; clippy -D warnings clean.

be5df06a48 feat(project-tool): bound-plan staleness check (content fingerprint)
`pic plan` now records a fingerprint of the live state it diffed against;
`pic apply` replays it and the server refuses (HTTP 409) if the app
changed underneath the reviewed plan — the §4.2 "apply exactly what you
reviewed" guarantee, in its content-addressed form (no migration, no
changes to interactive write paths).

Server (manager-core):
- `state_token(CurrentState)`: deterministic FNV-1a fingerprint over what
  the diff keys on — script name+version (version bumps on any edit),
  route identity+binding/attrs, trigger membership+enabled, secret names.
  Order-independent; a collision can only yield a false "unchanged", never
  a false refusal.
- `plan` returns it (flattened onto the plan JSON, so the wire stays
  additive); `apply` takes an optional `expected_token` and, under the
  apply lock before any write, returns `StateMoved` (409) on mismatch.

CLI:
- `.picloud/` link state (`linkstate`): `pic plan` writes the token scoped
  to the app slug; `pic apply` replays it, then clears it on success (the
  token is single-use — the next apply re-plans). `--force` skips the
  check; apply with no recorded plan still works standalone (today's
  behavior). `.picloud/` is already gitignored by `pic init`.

The tree-structure version (the other half of §4.2's counter) stays a
deliberate no-op until groups exist — it only guards reparent/structural
moves, which don't exist single-app.

Tested: state_token unit test (stable/order-independent/sensitive) + a
staleness journey (plan → out-of-band deploy → apply refuses → --force
applies); manager-core lib 363 + cli bins 31 + 13 journeys green; clippy
-D warnings clean.

d9b3e9973c fix(project-tool): address review findings on the apply foundation
Remediation of the single-app reconcile foundation after two independent
review passes. No new feature surface — closes correctness, parity, and
safety gaps in pull/plan/apply/prune.

apply engine (manager-core):
- validate_bundle reached parity with the interactive trigger API: reject
  an empty kv/docs/files collection_glob and a malformed pubsub
  topic_pattern (previously written and silently never matched), and lift
  the queue visibility floor to MIN_QUEUE_VISIBILITY_TIMEOUT_SECS (30) —
  apply had accepted a [5,29] value the dashboard refuses. Per-kind checks
  extracted into a pure, unit-tested validate_trigger_shape.
- An omitted script `description` now means "leave as-is" (matching the
  other optional fields and the function's own documented contract)
  instead of clearing the stored value.
- Doc fixes: drop stale "next milestone" notes; record the one deliberate
  plan/apply divergence (set-but-empty secret); document delete_route_tx
  as intentionally idempotent for reconcile.

CLI:
- Gate destructive `apply --prune` behind confirmation: interactive y/N,
  or `--yes` for CI; a non-interactive prune without `--yes` refuses
  rather than silently deleting. Journey tests pass `--yes`; a new test
  proves the gate refuses and deletes nothing.
- Harden pull's filename safety: reject all control characters and the
  Unicode bidi-override / zero-width chars used for terminal/filename
  spoofing, and cap length at 200 bytes (NAME_MAX headroom).

Tested: manager-core lib (incl. queue-floor + sparse-description parity)
+ CLI bins + 9 project-tool journeys green; clippy -D warnings clean.

3b650a2b14 feat: declarative project-tool foundation (pull/plan/apply/prune)
Add a server-side, atomic, declarative reconcile loop for a single app —
the foundation of the project-tool design. Developers describe an app's
scripts, routes, triggers, and secret-names in `picloud.toml`, then
`pic pull / plan / apply [--prune]` to converge live state to the manifest.

Server (manager-core):
- apply_service: a pure diff engine (compute_diff) shared by plan and
  apply, plus an ApplyService that composes the existing per-repo writes
  into ONE Postgres transaction. Identity keys mirror the DB UNIQUE
  constraints (script=lower(name); route=(method,host_kind,host,
  path_kind,path); trigger=per-kind semantic tuple; secret=name).
  Apply takes a per-app advisory lock, recomputes the diff in-tx, applies
  scripts -> routes -> triggers, prunes dependents-first, commits, then
  refreshes the route table once post-commit.
- apply_api: POST /apps/{id}/plan (AppRead) and /apps/{id}/apply.
  Apply requires the per-kind write caps the bundle exercises (all three
  when --prune), plus AppSecretsRead when it binds an email trigger.
- tx-accepting repo siblings (insert/update/delete *_tx) so the existing
  create/update/delete delegate to one SQL definition each.
- email triggers reference an inbound secret by NAME; the value is
  resolved, decrypted (AAD-bound), and re-sealed server-side at apply —
  it never travels in the manifest.

CLI (picloud-cli):
- manifest.rs (picloud.toml model), client plan/apply, and the pull/plan/
  apply commands. pull rejects filesystem-unsafe script names up front.

Safety properties enforced and tested:
- idempotent: a freshly-pulled manifest re-applies as all-NoOp.
- atomic: a mid-bundle failure rolls back with nothing written.
- routes delete-before-insert so a freed binding is reusable in one apply.
- queue one-consumer invariant held inside the shared tx.
- email triggers are never pruned, and a script that still owns an
  email/dead-letter trigger can't be pruned (the FK cascade would destroy
  the sealed secret) — refused with a pointer to `pic triggers rm`.
- plan and apply agree on unset email-secret references.

No migration: the existing schema's UNIQUE constraints serve as identity
keys. Groups, env-scoping, and the `enabled` toggle are later milestones.

Tested: manager-core lib (360) + CLI bins (27) + 8 project-tool journeys
(pull/plan/apply/prune/email+queue), all green; clippy -D warnings clean.

51f14fa2b1 feat: E2E #2 (Stash) gap remediation + S6 hardening
Some checks failed
CI / Rust — fmt, clippy, test (push) Failing after 6m19s
CI / Dashboard — check (push) Successful in 9m48s
Closes the gaps and the one security finding from the second end-to-end
CLI test (E2E_STASH_REPORT.md), plus the H1 boot-regression found while
re-reviewing those fixes.

Security
- S6: reserved-path validation (`check_reserved`) now case-folds before
  comparing, so `/API/v2/x`, `/HEALTHZ`, `/Admin/x` are rejected like
  their lowercase forms. Request-time matching stays case-sensitive.
- S10: "public route != public data" callout in sdk-shape.md (script_gate
  skips authz when the principal is anonymous).

Observability / features
- G1: trigger executions now write `execution_logs`. Migration 0043 adds
  a `source` column (CHECK mirrors ExecutionSource/OutboxSourceKind,
  DEFAULT 'http' backfills history); a shared `build_execution_log` helper
  in executor-core; dispatcher logging for outbox triggers + queue
  consumers (skips sync-HTTP rows the orchestrator already logs). `pic
  logs` gains a source column + `--source` filter.
- G5: dev-only in-memory email capture under PICLOUD_DEV_MODE with no SMTP
  (email::send succeeds locally), readable at GET /api/v1/admin/dev/emails
  (Owner/Admin only; route mounted only in capture mode).
- G6: generalized the Rhai in-place-mutation footgun note (trim/replace/
  make_upper/make_lower/crop/truncate/pad return ()).
- G2/G3/G4 (CLI): `pic members`, `pic files`, `pic queues`, read-only
  `pic kv` (+ new kv_api.rs); `pic deploy --timeout/--memory/--kind/
  --sandbox`; first-class `pic triggers create-{docs,files,pubsub,queue,
  email}` wrappers. All new client path segments percent-encoded via seg().

H1 regression fix (found in re-review)
- The S6 change also runs in `compile_routes`, which compiles every stored
  route at boot and on each route CRUD. A single stored route the new
  validation rejects (creatable while the S6 gap existed) made the whole
  compile Err and aborted startup. `compile_routes` is now lenient: it
  skips an un-compilable row with a warning instead of bricking boot
  (route creation still validates separately). Migration 0044 sweeps
  pre-existing reserved-path routes on upgrade (WHERE mirrors
  check_reserved exactly). Added regression tests for both.

Verified: cargo fmt, clippy --all-targets --all-features -D warnings, the
schema_snapshot test, and the new S6/lenient-compile unit tests all pass;
boot-resilience and G1/G5 confirmed live.

a91b134285 fix(review): harden the E2E-gap fixes after security/regression review
Addresses findings from an independent review of the gap-closing commits:

- R1 (regression): add #[serde(default)] to HttpDispatchPayload.method so
  async-HTTP outbox rows enqueued before the field existed still decode
  after upgrade instead of dead-lettering on "missing field `method`".
  Adds a regression test for the missing-key path.
- method case: uppercase ctx.request.method at the orchestrator boundary
  so it honors its documented "uppercased" contract for extension verbs.
  Route matching is already case-insensitive, so matching is unaffected.
- CLI hardening: percent-encode free-form path segments (app slug, topic
  name, ids, secret name) in the reqwest client so a value containing
  `/ ? #` can't break out of its URL segment. Adds a `seg()` helper +
  unit test and applies it uniformly across all path-interpolating
  methods (new and pre-existing).
- S1 (docs): correct the users::email_available enumeration framing — it
  adds no new vector vs. create's uniqueness error, but is cheaper and
  unthrottled; there is no built-in throttle/CAPTCHA primitive, so the
  honest mitigation is a kv-based counter. Updated SDK doc-comments,
  trait docs, and stdlib-reference.

7ffbb8de87 feat(sdk): users::email_available for anonymous registration pre-check (S1)
`users::find_by_email` requires an authenticated principal (F-S-003,
anti-enumeration), so the natural check-then-create register pattern 502s
for anonymous public scripts. Add `users::email_available(email) -> bool`,
gated like `create` (the registration write path) but without the
anonymous rejection: it leaks only a single boolean — no more than
`create`'s own uniqueness error already does — so self-serve register
scripts can pre-check. Also document find_by_email's principal
requirement in the SDK doc-comment.

ae2134e62d feat(executor): expose ctx.request.method to scripts (F4)
The request map exposed path/headers/body/params/query/rest but not the
HTTP method, forcing one script per verb (the E2E app needed 7 scripts
where ~3 would do). Add a `method` field to ExecRequest (populated from
the HTTP method on the sync-execute bypass and the HTTP outbox payload;
empty for non-HTTP triggers) and surface it as `ctx.request.method`,
uppercased. A single script can now branch GET/POST on one route.

dd9d828018 docs(audit-2026-06-11/tier3): fix stale principal_cache field comment
Review nit — the field is a non-optional Arc; the old '`None` for tests'
note was stale. Clarify that it's one shared Arc so revocation-side
evictions are visible to the middleware's resolve-side lookup.

e8cc3afa07 fix(audit-2026-06-11/H-B1 follow-up): use last X-Forwarded-For hop for login rate-limit key
extract_remote_ip took the FIRST X-Forwarded-For entry, but Caddy (the
single trusted proxy) appends the real peer as the LAST hop — earlier
entries are client-supplied. An attacker could prepend a rotating
X-Forwarded-For value to get a fresh per-IP bucket every request and
evade the per-IP login limiter (the per-username bucket + global Argon2
semaphore still bounded it, but the per-IP layer was defeated). Take the
last hop so the key reflects the real client. Added unit tests covering
the spoof, the single-hop case, and the missing-header fallback.

3ac1022c33 fix(audit-2026-06-11/H-1): request-body ceilings (Caddy proxy + email-inbound webhook)
- Caddy request_body { max_size 12MB } in both Caddyfiles — a hard
  ceiling replacing Caddy's multi-GB default; 12MB clears the
  orchestrator's 10 MiB user-route read. Validated with caddy validate.
- email-inbound router gets an explicit DefaultBodyLimit::max(1MB):
  the public unauthenticated webhook previously rode Axum's 2MB
  extractor default; tightened so a flood can't force large
  allocation + JSON parse per request.

Admin / execute handlers keep Axum's 2MB extractor default (already
bounded); the user-route path keeps its explicit 10 MiB manual read.

d9fb0e7f85 fix(audit-2026-06-11/F-FS-002): belt-and-suspenders collection validation on files read/delete
The admin files endpoints hit FsFilesRepo directly (not via
FilesServiceImpl, which validates), so only create/update guarded the
collection — head/get/list/delete built FS paths from an unvalidated
value. Today nothing can store a traversal-shaped collection, but one
future bad migration / restore tool inserting collection='../../etc'
would give the read/delete paths arbitrary host-file reach.

- FsFilesRepo::{head,get,list,delete} now call guard_collection (create
  and update already did).
- The three admin endpoints (list/get/delete) call
  validate_files_collection up front for a clean 422 instead of the
  repo guard surfacing as an opaque 500.

31ecfae86e fix(audit-2026-06-11/revocation-lag): evict PrincipalCache on credential change
The PrincipalCache (token-hash -> resolved Principal, 60s TTL) had no
eviction hook, so deactivation / password change / API-key revocation
flipped the DB rows but the cache kept serving the stale principal for
up to the TTL window. Closes the audit's PrincipalCache revocation-lag
Medium and greens authz::deactivating_user_revokes_their_api_keys.

- PrincipalCache::evict_user(user_id) + evict_token(hash).
- One shared cache Arc threaded into AuthState / AdminsState /
  ApiKeysState (a per-state cache would let the middleware's own copy
  keep authenticating a revoked principal).
- Evict on: deactivation, password change (both evict_user), logout
  (evict_token, precise), single API-key delete (evict_user).
- H-E1 note: DB-write invalidation stays best-effort by design (a blip
  must not undo the rotation); the cache evict is what makes it take
  effect on the next request.
- Renamed bearer_and_cookie_produce_same_principal ->
  session_token_and_api_key_produce_same_principal (cookie auth was
  removed in C-1; the test never tested cookies).

513c4a2d3c fix(audit-2026-06-11/H-D1): bind AES-GCM AAD on secrets + realtime signing key
At-rest secrets were AES-256-GCM sealed with no Associated
Authentication Data, so anyone with Postgres write access could
ciphertext-swap rows across apps (or rename via row edit) and the
decrypt would silently succeed under the wrong identity, returning
attacker-chosen plaintext. This breaks the cross-app isolation boundary
the moment DB write access is achieved.

Adds an AAD-bound envelope (v1) alongside the legacy no-AAD layout (v0),
discriminated by a per-row `version` column:

* shared::crypto — new encrypt_with_aad / decrypt_with_aad using
  aes_gcm::aead::Payload { msg, aad }. Originals retained for v0 reads.
  Tests: AAD round-trip, AAD-mismatch fails, empty-AAD round-trip.

* migration 0042 — adds `secrets.version SMALLINT NOT NULL DEFAULT 0`
  and `app_secrets.realtime_signing_key_version SMALLINT NOT NULL
  DEFAULT 0`. Existing rows stay v0; new writes are v1.

* secrets (SDK + admin API) — seal() now binds AAD =
  "secret:{app_id}:{name}" and emits v1; open() dispatches on version.
  StoredSecret gains a `version` field; SecretsRepo::set takes it.
  Both secrets_service::set and secrets_api::set_secret go through the
  v1 path. Tests prove a cross-app swap and a cross-name swap both
  surface Corrupted, and that a hand-built v0 row still decrypts.

* app_secrets (realtime signing key) — get_or_create_signing_key writes
  v1 with AAD = "app_secret:{app_id}:realtime_signing_key"; decode
  dispatches on version. Tests cover v0 decode, v1 round-trip, and v1
  decode-under-wrong-app failing.

* email-trigger inbound secret — kept on v0 (seal_legacy/open_legacy)
  and explicitly deferred: email_trigger_details has no version column
  and the trigger_id isn't known at seal time. The audit classes the
  email-trigger AAD gap as Medium; folded into v1.2's key-versioning
  pass per SECURITY_AUDIT.md.

* expected_schema.txt re-blessed by hand (no local Postgres) for the two
  new columns + migration 0042.

Also folds in a let-else clippy fix in auth_api.rs (login Argon2
semaphore acquire, from the H-B1 commit) and two cargo-fmt reflows.

No re-encryption sweep — v0 rows decrypt as-is; the sweep is deferred to
v1.2's key-versioning pass (audit "Notes on remediation methodology").

34c63f31be fix(audit-2026-06-11/H-H1): rate-limit email::send + per-message recipient cap
The Rhai SDK email::send path went straight to the SMTP relay with no
admission control. EmailRateLimiter lived in users_service.rs (gating
verification + password-reset emails) but was unreachable from the SDK
surface. Any anonymous-callable HTTP-route script could loop email::send
to burn the operator's SMTP quota or BCC-bomb thousands of recipients
per request.

Two new caps on EmailServiceImpl, both fire BEFORE message assembly +
SMTP connect:

1. Per-message recipient cap (to+cc+bcc combined). Default 20, override
   with PICLOUD_EMAIL_MAX_RECIPIENTS. New EmailError::TooManyRecipients
   variant. Closes the BCC-bomb amplification path.

2. EmailRateLimiter inlined into EmailServiceImpl:
   * Per-(app, recipient): RECIPIENT_BURST=5 / RECIPIENT_WINDOW=60min.
   * Per-app daily: APP_DAILY_CAP=200 / 24h.
   The structure mirrors users_service's private limiter; defense-in-
   depth redundancy is fine since the gates are identical and never
   conflict. New EmailError::RateLimited(&'static str) variant; the
   string names which bucket tripped so the operator can act.

users_service::map_email_error grows two cases (mapped to
EmailTransport for the script-facing error shape).

Tests:
* too_many_recipients_rejected — 30 recipients, default cap 20, rejected
  with TooManyRecipients.
* per_recipient_burst_caps_repeated_send_to_same_address — 6 sends to
  the same address; 6th returns RateLimited("per-recipient burst").

8b5a02b3ef fix(audit-2026-06-11/H-B2): inbound_secret mandatory + bad-signature lockout on email triggers
Two gaps:

1. /api/v1/admin/apps/{id}/triggers/email accepted `inbound_secret: null`
   and treated it as "this trigger is unsigned". The runtime then
   skipped HMAC verification entirely. URL discovery (logs, ops
   dashboards, bruteforce on the 122-bit TriggerId space) then fan-out-
   amplified into the outbox for free — anonymous DoS via the
   dispatcher.

2. Even signed triggers had no per-trigger rate limit on signature-
   verify failures, so an attacker who knew the URL could pump unsigned
   POSTs to force Argon2-equivalent work (HMAC verify + nonce-dedup +
   stored-secret decrypt) at line rate.

Fix:

* triggers_api::create_email_trigger now requires a non-empty
  inbound_secret. 400 on missing / empty / whitespace-only.
* email_inbound_api::receive_inbound_email returns 401 immediately when
  the resolved target has no inbound_secret_encrypted column (pre-fix
  rows). The previous `if let Some(ct), Some(nonce)` branch is gone.
* New `BadSignatureLimiter`: per-`(app_id, trigger_id)` sliding-window
  bucket (10 fails / 60 s). On lockout the receiver returns 429 with
  Retry-After instead of 401. record_failure runs on both the
  "no-secret" 401 path and any verify_signature failure.

Test fallout:
* email_inbound integration tests that relied on None secret: removed
  the now-impossible `unsigned_trigger_accepts_without_signature` test,
  replaced with `create_without_inbound_secret_is_rejected` covering
  null / "" / "   "; updated `malformed_body_is_422` and
  `cross_app_path_is_404` to pass + sign with a secret.
* Two new unit tests pin the limiter behavior (burst lockout + per-
  trigger independence).

07ffc0b568 fix(audit-2026-06-11/H-B1): login rate limit + Argon2 concurrency cap
The login handler had no admission control before
`spawn_blocking(verify_password)`. On Pi-class hardware Argon2id is ~50-
100 ms per attempt, so a few dozen concurrent anonymous POSTs to
/auth/login park every blocking worker, wedging the entire admin API
and any other path that uses `spawn_blocking`.

Adds two cheap, in-process guards modeled on EmailRateLimiter:

* `LoginRateLimiter` — two sliding-window token buckets, one per
  `(remote_ip, username)` (burst 5/60s) and one per `username`
  (burst 10/15min). Per-(ip, user) defeats a single attacker pounding
  one account; per-user defeats credential-stuffing distributed across
  many IPs. Username is case-folded so case variants share a bucket.
  Maps GC lazily when they cross a soft size cap.

* Per-process `tokio::sync::Semaphore` — caps concurrent Argon2 verifies
  during login. Default 2 permits (Pi-class), overridable via
  `PICLOUD_LOGIN_ARGON2_PARALLELISM`. Acquired AFTER the bucket check so
  attackers can't queue.

Limit check fires before the DB credentials lookup, so even an unknown
username doesn't cost a query. Denied attempts return 429 + Retry-After.
Real client IP comes from the first X-Forwarded-For entry (Caddy is the
trusted single hop); falls back to "unknown" so the per-user bucket
still gates.

4 unit tests cover bucket burst exhaustion, per-user crossing IPs, case
folding, and per-user independence.

bd64a25c97 fix(audit-2026-06-11/H-F1): dispatcher same-app guards on queue + HTTP arms
build_invoke_request already asserts `script.app_id == row.app_id`
(dispatcher.rs:752) before constructing an ExecRequest. The queue
dispatcher (`dispatch_one_queue`) and the HTTP outbox arm
(`build_http_request`) did not. validate_trigger_target blocks cross-
app registration at write time, so the gap was latent; but a hand-
edited row, a partial backup restore, or a script re-pointed across
apps post-hoc could otherwise execute one app's script under another
app's SdkCallCx, breaking the cross-app isolation boundary the SDK
relies on.

Adds the runtime guard at both sites:
* dispatch_one_queue — on mismatch, dead-letter the message so the
  misfire is observable rather than silently dropped, and short-
  circuit.
* build_http_request — on mismatch, return ResolveTrigger error; the
  outer dispatch arm logs + drops the row (same path as decode
  failures).

2af8ee49ba fix(audit-2026-06-11/H-E1): password change invalidates sessions + API keys
The PATCH /api/v1/admin/admins/{id} handler's password branch updated
the password hash but explicitly preserved every live session and API
key for the target user. That made password rotation a non-event for
credential compromise: a hijacked session that triggered a password
change kept its grip after the rotation, and a leaked API key survived
its owner's "I'm rotating because I think I'm compromised" reaction.

Now the password branch mirrors the deactivation branch:
1. update the password hash (unchanged),
2. `state.sessions.delete_for_user(id)` — wipes every live session
   including the caller's, which logs them out and forces re-login
   under the new password,
3. `state.keys.expire_all_for_user(id)` — revokes every API key.

This matches the `cmd_reset_password` CLI flow already in the codebase.
The dashboard's 401 handler redirects to the login screen, so the UX
on self-change is "you're logged out; sign back in".

fde4796479 fix(audit-2026-06-11/C-2): file download attachment + nosniff + CSP + MIME allowlist
Stored XSS: the previous get_file handler streamed user-supplied bytes
with Content-Disposition: inline, the user-supplied Content-Type, and
no X-Content-Type-Options / CSP. A Rhai script could store an SVG or
HTML payload whose download URL rendered same-origin under the admin
session cookie.

Closes the response side and the storage side:

* shared::sanitize_stored_content_type: allowlist
  (octet-stream/pdf/json/text-plain/text-csv/image-non-svg/audio/video)
  with anything else coerced to application/octet-stream. New unit tests
  cover the safe/unsafe/case-insensitive/parameter-preserving paths.

* files_service::create/update: sanitize the stored content_type after
  the shape checks pass (sanitize-after-validate keeps the existing
  MissingField / TooLong errors intact). Two new tests confirm text/html
  and image/svg+xml are coerced to application/octet-stream on
  create/update respectively.

* files_api::get_file (admin download):
  - Content-Disposition: attachment (was inline)
  - Content-Type re-sanitized via the shared helper as belt-and-
    suspenders for any pre-existing row that pre-dates this change.
  - X-Content-Type-Options: nosniff
  - Content-Security-Policy: default-src 'none'; sandbox;
    frame-ancestors 'none'
  - Referrer-Policy: no-referrer

b096ea9c4e fix(audit-2026-06-11/C-1): drop cookie auth on /api/v1/admin/*
Same-origin CSRF: the platform co-hosts user-route HTML on the same
origin as /api/v1/admin/*; SameSite=Lax did not block a same-origin POST
from a malicious script at /<route>, riding the admin's picloud_session
cookie. The dashboard already uses Bearer (dashboard/src/lib/auth.ts +
api.ts:495), so cookie auth was dead weight on the admin side and
exploitable.

Cuts the cookie path entirely:
- auth_middleware::extract_token is Bearer-only; cookie branch removed.
- auth_api::login no longer sets Set-Cookie.
- auth_api::logout no longer clears the cookie (the bearer token is
  still revoked by deleting the session row).
- extract_token_for_logout matches.
- SESSION_COOKIE const + PICLOUD_COOKIE_SECURE env var deleted.

285a76f2e2 refactor(manager-core): single source for executor-timeout default
Stage 6 review Obs 1b: the 300s default lived as a literal in two
places (DEFAULT_ASYNC_EXEC_TIMEOUT in dispatcher.rs and
DEFAULT_SAFE_VISIBILITY_VS_EXEC_BUDGET_SECS in triggers_api.rs). A
future change to the dispatcher would silently leave the
visibility-timeout warn threshold out of sync.

Extract a single pub const DEFAULT_ASYNC_EXEC_TIMEOUT_SECS: u32 = 300
in dispatcher.rs, derive the existing Duration constant from it, and
re-export it under the triggers_api name so the validator's
self-contained semantics are preserved at the call site. Tests still
inject the value explicitly via TEST_SAFE_LIMIT — no behavior change.

e33a551ad5 fix(manager-core): visibility-timeout warn threshold tracks live env budget
Stage 6 follow-up Obs 1: the hard-coded
SAFE_VISIBILITY_VS_EXEC_BUDGET_SECS = 300 didn't follow
PICLOUD_DISPATCHER_ASYNC_EXEC_TIMEOUT_SEC. A deploy that raised the
executor budget produced false-positive warns; a deploy that lowered
it missed real visibility races.

Refactor validate_queue_visibility_timeout to take safe_limit_secs as
an explicit parameter. The call site reads the live env-overridable
value via safe_visibility_vs_exec_budget_secs() each call; unit tests
inject the boundary directly without touching global env state. New
test safe_limit_threshold_tracks_caller_value asserts both
budget-raised and budget-lowered code paths.

b0f7b72dd6 fix(review): close 5 follow-up gaps from Stage 6 audit re-review
- F-T-003 actually closed: clients/typescript/src/subscribe.ts now
  bounds the 401-refresh loop at 3 consecutive refusals, surfaces an
  onError describing the loop, and resets on any successful stream
  open. New test covers the cap. The Stage 2 dashboard fix only
  addressed adminRequest in dashboard/src/lib/api.ts; the originally-
  cited TS client file was untouched.

- users/invitations subtab dropped the redundant api.apps.get fetch
  the other 5 subtabs already shed in Stage 6.

- Queue visibility-timeout validator pulled out as
  validate_queue_visibility_timeout, with two thresholds: hard-reject
  below MIN_QUEUE_VISIBILITY_TIMEOUT_SECS (30s — catches typos), warn-
  log between MIN and SAFE_VISIBILITY_VS_EXEC_BUDGET_SECS (300s) so
  operators see when their visibility is below the dispatcher's
  per-message executor budget. Stage 6 only had the hard floor; the
  reviewer caught that a 60s handler still races a 30s visibility
  even after the floor. Four new unit tests cover none/above-safe/
  between/below-min.

- pic dead-letters count subcommand: cheap headless probe for
  unresolved DL totals, parallels the dashboard's badge query.

- pic dead-letters replay now has a happy-path integration test
  (replay_against_real_dl_row_succeeds): inserts a synthetic DL row
  directly via the rust-postgres sync driver (added as dev-dep),
  drives `pic dead-letters replay`, asserts the row is resolved with
  reason=replayed and count drops back to 0. Plus a count smoke test.

All 75 CLI integration tests + 16 TS client tests + 4 new
visibility-timeout unit tests pass.

05ed9b00bb fix(stage-6): dashboard hardening + audit Lows cherry-pick
Closes 4 dashboard hardening findings and 5 of the Lows from the audit.

Dashboard hardening:
- Subtabs no longer re-fetch the app via api.apps.get on every page
  load. users/files/dead-letters drop the fetch outright (the variable
  was set but never read); queues + queues/[name] now consume the
  layout's AppContext via getContext for the page title. The layout's
  reloadApp() owns the historical-slug redirect — subtab-local redirect
  blocks are removed so there's no race.
- The global :global(details > summary::before) chevron is now scoped
  to details.chevron. The script editor's "Advanced sandbox" details
  and the inbound-email-shape help-text both opt in; the script
  exec-list logs no longer inherit a spurious chevron.
- deriveTab now matches the path segment by anchored ===, so a future
  /apps/<slug>/queues-archived route wouldn't activate the queues tab.

Lows cherry-pick:
- ExecError gains Serialize/Deserialize derives + a snake_case tag so
  RemoteExecutorClient (cluster mode v1.3+) can round-trip the variant.
- triggers_api rejects queue triggers whose visibility_timeout_secs is
  below the dispatcher's per-message executor budget; with no minimum
  the reclaim task races the handler and the queue silently
  double-delivers. Existing test using 5s updated to 30s.
- New migration 0040: execution_logs.script_id cascade switched from
  ON DELETE CASCADE to ON DELETE SET NULL so deleting a script no
  longer wipes the forensic history that motivated the delete.
- New migration 0041: dead_letters composite index on
  (app_id, created_at DESC) so the "list all" dashboard view stops
  falling back to seqscan + sort when unresolved=false.
- Schema snapshot re-blessed.

Deferred to v1.2: the ExecRequest principal serde(skip) marker
(documented in-place; the cluster-mode PR will introduce the wire-safe
snapshot at that point) and the `pic --help` mention of
`picloud admin reset-password` (one-line follow-up).

649246213e fix(stage-3): queue DL fan-out + emit-failure visibility
Closes the queue DL fan-out gap (audit Medium) and surfaces the
KV/docs/files non-transactional emit gap to operators.

- handle_queue_failure previously called queue.dead_letter to write the
  DL row but never invoked fan_out_dead_letter. The comment claimed
  "the outbox arm fires registered dead_letter handlers off the new row"
  — but queue DL rows are written via a separate path that bypasses the
  outbox entirely, so handlers filtered on source="queue" sat idle
  forever. Refactor fan_out_dead_letter to take a DeadLetterFanOutCtx
  struct so both the outbox arm and the queue arm can call it; the
  queue arm constructs a TriggerEvent::Queue from the claimed message
  and passes it through.

- New integration test queue_dead_letter_fans_out_to_dead_letter_handler
  registers a dead_letter trigger filtered on "queue", forces queue
  exhaustion, asserts the handler fires with the correctly-shaped event.

- KV/docs/files services committed the data write then ran events.emit
  as a separate operation, logging-and-swallowing on failure. Bump the
  six call sites from tracing::warn to tracing::error with an
  event_emit_failure=true marker so operators can grep them. The full
  single-tx repo refactor (extending ServiceEventEmitter with
  emit_in_tx + tx-aware *_repo methods) is documented in kv_service.rs
  as a v1.2 follow-up — it's a meaningful redesign that deserves its
  own pass (pubsub_service::fan_out_publish is the reference shape).

f466b2a15e fix(stage-2): audit dashboard TS alignment + login UX
Closes 4 audit findings:

- Route TS interface now carries dispatch_mode (sync|async). Backend's
  shared::route::Route has had this since 0012_routes_dispatch_mode but
  the TS client silently always created sync routes and the list
  display dropped the field. Add a Dispatch select to the new-route
  form and an "ASYNC" badge in the route list.

- api.files.downloadUrl pointed to a never-registered backend endpoint.
  The dashboard's live Download button was hitting 405. Add the GET
  handler (AppFilesRead + FilesRepo::head + FilesRepo::get, Content-
  Disposition: inline) at the same path that delete already used.

- F-T-003: adminRequest's 401 handler called goto(login) without a
  recursion cap. If the login endpoint itself returned 401, the wrapper
  looped until browser nav limits. Track consecutive 401s within a 10s
  window and hard-reload to /login?reason=auth-loop after the third,
  showing the user an explanatory banner. Any 2xx resets the counter.

- Login flow now honors a ?returnTo= query parameter. adminRequest and
  the root layout both append the current location when redirecting to
  /login; the login page validates the value is a same-origin admin
  path (no open-redirect) and goto's there after successful sign-in.

3c9816daf3 fix(stage-1): audit High-severity backend correctness + CI unblocker
Closes 4 High-severity audit findings:

- describe_event broken for HTTP-async payloads: was reading source/op
  JSON fields that HttpDispatchPayload doesn't carry, producing empty
  source on DL rows. from_wire("") then fell back to Kv on replay, the
  dispatcher tried to resolve a non-existent trigger, and replay no-op'd
  silently. Now branches on OutboxSourceKind: HTTP rows emit
  "<method> <path>" + source="http"; Invoke rows emit "invoke_async" +
  source="invoke"; TriggerEvent payloads keep top-level field extraction.

- HTTP outbound Authorization leaked across cross-origin redirects.
  Manual redirect loop (Policy::none) reused header_map on every hop
  and only scrubbed Content-Type for POST->GET. Now compares
  url::Url::origin() across hops and strips Authorization,
  Proxy-Authorization, Cookie when origin changes — matching reqwest's
  default policy.

- F-S-010 inbound email HMAC had no replay protection. Signature was
  computed over body only with no timestamp or nonce, so captured POSTs
  were replayable indefinitely. Adds X-Picloud-Timestamp header bound
  into the HMAC input (signed string is ts || "." || body), 300s
  tolerance window, and a process-local LRU keyed on
  (ts, sha256(body)) with 600s TTL to catch within-window replays.
  Breaking change: webhook senders must include the timestamp header.

- expected_schema.txt re-blessed for migrations 0036-0039 (the previous
  snapshot stopped at 0035 so CI would have gone red on first run).

a1b7569d05 fix: post-review followups on slug-vs-UUID refactor
Addresses every finding from the four-agent review of commit aa493b9.

Dashboard — honor redirect_to on subtab loadApp() (closes the silent
historical-slug redirect UX gap):

  - queues/+page.svelte
  - queues/[name]/+page.svelte
  - files/+page.svelte
  - dead-letters/+page.svelte

  After a rename, the URL bar now reflects the canonical slug instead
  of silently rendering the renamed app's data under the stale URL.
  Mirrors the established pattern at apps/[slug]/+page.svelte:619-623.

manager-core:
  - queues_api.rs IntoResponse now uses the JSON envelope shape
    `{"error": "..."}` consistent with every sibling admin api file.
  - triggers_api::delete_trigger reordered: cap check fires BEFORE the
    trigger load, closing the 404-vs-403 existence side channel an
    unauthorized caller could otherwise probe.
  - InMemoryAppRepo mocks in topics_api + triggers_api now implement
    get_by_slug + get_by_slug_or_history (previously
    `unimplemented!()`), unblocking handler-level slug-input tests.
  - Added 4 slug-acceptance tests to topics_api and 2 to triggers_api
    (slug-resolves, unknown-slug-404, historical-slug-resolves,
    create-via-slug). Also added delete-without-cap-is-forbidden test
    pinning the new cap-first order.

e2e:
  - navigation/tabs.spec.ts split per-tab so a regression on one tab
    no longer masks regressions on the others.
  - Negative assertion widened: captures every /api/v1/admin/apps/*
    response and fails on any 4xx/5xx — not just the literal "Cannot
    parse" string. Catches a broader regression shape.
  - networkidle replaced with `expect(<main>).toBeVisible()` —
    networkidle is officially discouraged for SPAs and was at risk of
    timing out behind the queues auto-refresh.
  - Cleanup registration moved BEFORE the create-app API call so a
    flaky create still gets swept up.
  - Queue drilldown route /queues/[name] now covered.
  - Stable `data-testid="queues-empty-state"` replaces fragile
    UI-copy substring match for the positive assertion.
  - Header comment now spells out what this spec does and doesn't
    catch.

docs:
  - serverless_cloud_blueprint.md: slug-history described as
    "200 OK + redirect_to" JSON envelope rather than "301 redirect"
    — matches what apps_api actually implements (SPA can't honor a
    mid-tree HTTP redirect).

Unit-test gap (acknowledged): queues_api, files_api, secrets_api,
dead_letters_api have zero in-process tests. Adding them properly
needs a shared mock-repo helper crate — the standalone trait surface
(QueueRepo + TriggerRepo + ScriptRepository + AuthzRepo + repo-
specific) is ~30 methods per file. Documented inline in queues_api.rs
near the resolver. Integration coverage via crates/picloud/tests/ and
the new e2e spec cover the same paths end-to-end.

aa493b9326 fix(admin-api): accept slug or UUID on per-app endpoints
The Queues tab at /admin/apps/default/queues was returning
"Cannot parse `app_id` with value `default`: UUID parsing failed".
27 admin endpoints across 6 files used strict `Path<AppId>` instead
of the canonical `Path<String>` + `resolve_app()` pattern from
app_repo.rs:34. Working endpoints (apps, app_members, users_admin)
all use the lenient pattern; this commit brings the remaining 6
files into line:

- queues_api.rs       — 2 handlers
- files_api.rs        — 2 handlers
- secrets_api.rs      — 3 handlers
- topics_api.rs       — 4 handlers
- dead_letters_api.rs — 5 handlers
- triggers_api.rs     — 10 handlers

The handler bodies (authz, repo calls) are unchanged; only the path
extractor and the per-file `ensure_app_exists` helper (now renamed
`resolve_app`) move. Lib tests updated to pass `.to_string()` at
the call site (Path now takes String, not AppId).

email_inbound_api.rs deliberately stays strict-UUID — it's a public
webhook receiver consumed by external providers, not by the
slug-based dashboard.

Adds Playwright spec `dashboard/tests/e2e/navigation/tabs.spec.ts`
covering every per-app tab (queues, files, dead-letters, users,
invitations, plus the main page hosting triggers/secrets/topics)
with a negative assertion against the "Cannot parse" error text
plus a focused regression test for the original queues report.

f2b16da2b5 fix(manager-core): F-S-012 add AppInvoke capability + gate invoke() / invoke_async()
invoke_service::resolve and enqueue_async performed no authz check —
no AppInvoke capability existed. Same-app isolation was preserved
(cross-app guards work), but within one app an anonymous public-HTTP
script could trigger any other script (e.g. an admin-only worker that
hits secrets/files/external HTTP). Worse: invoke_async runs the
callee with principal: None, so the callee could hold capabilities
the original public caller shouldn't.

- Add Capability::AppInvoke(AppId). app_id() / scope_for_capability
  (script:write) / role_satisfies (editor+) are all updated.
- InvokeServiceImpl gains an optional `authz: Option<Arc<dyn AuthzRepo>>`
  + a `with_authz` builder. When set, resolve() runs script_gate on
  AppInvoke before doing the cross-app id check.
- picloud/src/lib.rs wires it: `InvokeServiceImpl::new(...).with_authz(...)`.
- Anonymous callers (cx.principal == None) continue to skip the check
  via script_gate, preserving the public-HTTP convention.

Existing 5 invoke_service unit tests still pass (the tests use the
authz-less constructor, so the gate is a no-op there).

1911691420 fix(manager-core): F-Q-011 blanket Arc<T: ScriptRepository> impl; delete PostgresScriptRepoHandle
A 70-line newtype lived in picloud/src/lib.rs wrapping
Arc<PostgresScriptRepository> and re-implementing every ScriptRepository
method as `self.0.method(...).await`. Hand-delegation invited silent
skew when the trait gained a method, and forced 8 call sites to know
about the wrapper.

Add a blanket
  impl<T: ScriptRepository + ?Sized> ScriptRepository for Arc<T>
in manager-core::repo. The implementations forward via (**self).method(...)
so any owner of an Arc<dyn ScriptRepository> (or Arc<ConcreteImpl>) can
be passed where the trait is expected.

Migrate the 7 picloud-binary call sites:
  Arc::new(PostgresScriptRepoHandle(script_repo.clone())) → script_repo.clone()

73d3befb06 fix(manager-core): F-Q-009 promote dispatcher tick + async-exec timeout to env-overridable

other timing knob in the file (cron tick, queue reclaim, retry policy)

dispatcher cadence.

- PICLOUD_DISPATCHER_ASYNC_EXEC_TIMEOUT_SEC (default 300)

59d4c043b0 fix(http): F-Q-008 add HttpError::InvalidArgs for user-input validation failures
http_service::run mapped `Method::from_bytes` failure on a user-supplied
HTTP method to HttpError::Backend with format!("invalid method: {}", …).
Same for HeaderName/HeaderValue validation in build_headers. But that's
user input, not a backend problem — misclassifying as Backend corrupts
retry policies (operators may retry "backend" but not "invalid input").

Add a new HttpError::InvalidArgs(String) variant. Reroute the three
validation paths in http_service (method, header name, header value) to
emit InvalidArgs instead of Backend.

The executor-side `map_http_err` uses Display, so the new variant
surfaces to scripts as "http: invalid method: …" — same format, more
structured behind it.

9cd1213aac fix(manager-core): F-S-013 partial unique index on app_user_invitations pending rows
No unique constraint on (app_id, lower(email)) for pending rows meant
calling users::invite("alice@…") N times created N rows with N valid
tokens. Combined with accept_invite returning Ok(None) silently when
the email already exists, an attacker who learned one token could
permanently consume it without effect.

Migration 0040 adds a partial unique index keyed on
(app_id, lower(email)) WHERE accepted_at IS NULL. Re-inviting after a

outside the index.

The service-layer 409-conflict UX (the audit's secondary suggestion)

0b7ef11333 fix(manager-core): F-M-002 coupled-nullness CHECK on encrypted-secret column pairs
Two (encrypted, nonce) column pairs are each nullable independently in
the current schema:
- email_trigger_details.inbound_secret_encrypted / _nonce
- app_secrets.realtime_signing_key_encrypted / _nonce

A bug or partial write could leave one populated and the other NULL,
silently bypassing signature verification (receivers decrypt only if
the encrypted column is set).

Migration 0038 adds CHECK ((enc IS NULL) = (nonce IS NULL)) on both
tables — defence-in-depth: catches an invariant violation at the DB
boundary even if the writing code regresses.

0bce113d28 fix(manager-core): F-M-001 drop unused idx_cron_triggers_due
Migration 0017_cron_triggers.sql created idx_cron_triggers_due on
(last_fired_at) with a comment claiming it serves the scheduler. The
actual scheduler query has no last_fired_at predicate — it filters
purely on `t.enabled = TRUE FOR UPDATE OF d SKIP LOCKED`. The index
has been pure write amplification with no read payoff.

Migration 0037 drops it. Reversible by re-running 0017's CREATE INDEX
if the planner story ever changes.

3c5978190e fix(manager-core): F-P-010 add idx_triggers_kind_enabled
list_active_queue_consumers fires every 100ms from the dispatcher
queue arm and predicates on `WHERE t.kind='queue' AND t.enabled=TRUE`
with no app_id filter — but the only available index
`idx_triggers_app_kind_enabled` is keyed on `(app_id, kind)` and so
requires an app_id predicate to be useful. Without one, the planner
falls back to a sequential scan every tick.

Add migration 0036 with a partial index on `kind` (WHERE enabled =
TRUE) so the hot dispatcher query becomes an index-only lookup.

4923fa89e3 fix(manager-core): F-S-008 TTL + invalidate hook on realtime_authority key cache
key_cache: Mutex<HashMap<AppId, Vec<u8>>> was populated on first read
and never evicted, bounded, or cleared on app deletion. Two problems:
(1) Once key rotation lands, every running process keeps accepting
tokens signed by the old key until restart.
(2) Dropping and re-creating an app (FK CASCADE removes app_secrets,
fresh row inserted) made the cache hand out the OLD key bytes.

- Wrap the cache value as `(Instant, Vec<u8>)`; entries expire after
  KEY_CACHE_TTL = 5min.
- Stale reads fall through to the secrets repo (no error, just slower).
- New `invalidate_signing_key(app_id)` for explicit eviction once the
  app-secrets rotation path lands.

f4189fc52f fix(manager-core): F-S-006 cap API-key candidate set at 16 (Argon2 CPU amplifier)
verify_api_key Argon2-verifies every candidate sharing the 8-char
prefix. With unlimited candidates, an attacker who can provision many
keys against one indexed prefix could force the server into per-request
M×Argon2 — a few hundred concurrent connections trivially DoSes the
manager since the verify runs before any concurrency cap.

Cap the candidate set at MAX_API_KEY_CANDIDATES = 16; log a warn when
truncation kicks in so operators can spot it. With 32-byte random key
bodies the natural collision rate is negligible, so truncation under
benign load shouldn't happen — its presence is the alarm.

Switching the verify hash from Argon2 to SHA-256 (the audit's other
suggested fix) is a larger refactor (new hash column, backfill, dual-
hash verify during migration) and is left for a follow-up.

7d045b2a0b fix(manager-core): F-S-005 gate dashboard delete_user on AppUsersAdmin
users_admin_api::delete_user was a comment-only acknowledgement that
"this should require AppUsersAdmin" while actually calling
service.delete which only gates on AppUsersWrite. v1.1.8 HANDBACK §7
listed this as known. Effect: any editor could delete app users via
the admin HTTP API and dashboard button.

Add an explicit `authz::require(... AppUsersAdmin(app_id))` before the
service call. Delete the stale comment.

9247680ab6 fix(manager-core): F-S-004 close timing oracle in users::request_password_reset
Handler returned immediately when email shape was invalid or user was
unknown; on a found user it generated an Argon2 token, INSERT'd into
app_user_password_resets, built a link, and called email.send (tens of
ms + DB write + SMTP RTT). The wall-clock delta was enormous and
externally observable.

Add a dummy generate_session_token() call on both no-match branches so
the observable cost matches the matching branch up to the Argon2 hash.
Doesn't equalise the DB INSERT + SMTP send (those would require either
real side effects or a deterministic dev-mode null sink), but it
neutralises the highest-bit-of-info side channel (handler-immediate-
return vs handler-token-mint).

Combined with F-S-003 (find_by_email now requires a principal),
enumeration via this surface from an anonymous public route is closed.

22e77e02f0 fix(manager-core): F-S-003 require authenticated principal for users::find_by_email
find_by_email gated on AppUsersRead via `require`, which short-circuits
when cx.principal == None. An anonymous public-HTTP script could
iterate emails to enumerate registered users, then pivot to login or
request_password_reset.

Tighten: explicitly return Forbidden when cx.principal is None — scripts
that need a "does this email exist" probe from a public route must
wrap the call in their own auth gate.

dc40bc7926 style: fmt + clippy cleanup after Phase B
cargo fmt regroups, plus three Phase-B clippy fixes:
- F-P-004: #[allow(clippy::type_complexity)] on the invoke_ast_cache Mutex.
- F-P-008: hoist `futures::stream::{self, TryStreamExt}` to the top-of-
  file imports to satisfy clippy::items_after_statements.
- F-P-005: rename `_legacy_offset` to `legacy_offset` + #[allow(dead_code)]
  to satisfy clippy's "field is pub but `_`-prefixed" check.

No behavior change.

617c216429 fix(manager-core): F-P-009 cache resolved Principals (60s TTL) in auth middleware
attach_principal_if_present runs on every request that carries a
Bearer header, including data-plane paths that may not even need
authz. Each call paid three DB round-trips on the session path
(lookup + admin_users.get + touch) plus an Argon2 verify per
prefix-colliding candidate on the API-key path. A hot user with
multiple keys serialized every request behind N×Argon2.

Add a process-shared PrincipalCache keyed on hash_token(bearer) →
(Instant, Principal), TTL 60s. resolve_principal checks the cache
first; on miss falls through to the verify_api_key / verify_session
path and writes back on success.

- Lazy GC: when the cache exceeds 1024 entries, sweep expired before
  inserting (kept simple — production sees few unique hot tokens).
- Cache wired through AuthState; constructed once in picloud/src/lib.rs.
- Skip-when-route-doesn't-need-auth scaffolding is deferred to a
  follow-up — it requires touching the router shape, which is more
  invasive than the 60s cache alone warrants.

c80ee194f2 fix(manager-core): F-P-008 concurrent trigger hydration in list_for_app (wall-clock fix)
TriggerRepo::list_for_app selected parent rows then called
hydrate_one(...) per row serially — one SELECT against the kind-
specific details table per trigger. For N triggers on an app, that's
N+1 queries serialized on every dashboard `GET /apps/{id}/triggers`.

This commit shrinks the wall-clock cost via buffered concurrency
(`try_buffered(8)`): each row's details fetch still runs but they run
in parallel up to a small fan-out cap. Cuts dashboard load time from
sum(N latencies) to max(N latencies) / 8.

Collapsing to a single per-kind LEFT JOIN (the audit's preferred shape)
would cut the query count to ~7 — large enough to defer to v1.2 as
documented in the inline comment.

8ceb1352dd fix(manager-core): F-P-007 concurrent queue dispatch per tick
tick_queue_arm called list_active_queue_consumers() and then iterated
serially, awaiting one queue.claim(app, queue) per consumer. With N
consumers and a 100ms tick the worst-case throughput was
N × (claim + executor) / tick — one slow handler blocked every other
queue's progress on the dispatcher's task.

Replace the for-loop with `futures::stream::iter(consumers)
.for_each_concurrent(QUEUE_DISPATCH_PARALLELISM, …)`. The execution
gate already caps real script-concurrency to its permits, so this just
removes the dispatcher-side serialization.

QUEUE_DISPATCH_PARALLELISM = 32 (matches the default gate). Workspace
gains `futures = 0.3` so `for_each_concurrent` is available.
