Durable pub/sub through the universal outbox — the sixth trigger kind.
- `pubsub::publish_durable(topic, message)` Rhai SDK (no handle; topics
ARE the grouping unit). Message JSON-encoded; Blobs base64 at any
depth.
- `PubsubService` trait in picloud-shared with the topic matcher +
validator (exact / `<prefix>.*` / `*`; mid-pattern wildcards
rejected). `PostgresPubsubRepo` + `PubsubServiceImpl` in manager-core.
- Publish-time fan-out: one outbox row per matching enabled pubsub
trigger, all in ONE transaction (no half-fan-out on crash). No
matching trigger → publish succeeds silently, zero rows.
- `pubsub:*` trigger kind via Layout-E (0020: widen both CHECKs +
pubsub_trigger_details + partial index), TriggerEvent::Pubsub +
ctx.event.pubsub, dispatcher arm, admin endpoint POST /triggers/pubsub
(validates topic pattern + reuses validate_trigger_target).
- AppPubsubPublish capability → script:write (seven-scope held).
- Dashboard Pub/Sub trigger form on the Triggers tab + list rendering.
publish_ephemeral stays deferred to v1.2. ~18 new tests (service
in-memory incl. transactional-rollback, shared matcher, bridge
encoding). No DB required for the suite.

Filesystem-backed blob storage as the fifth concrete trigger kind.
- `files::collection(c).{create,head,get,update,delete,list}` Rhai SDK
(blob in/out; metadata maps; missing-field throws naming the field).
- `FilesService` trait in picloud-shared; `FsFilesRepo` (atomic
write: temp→fsync→rename→fsync-dir→DB; single-pass SHA-256;
checksum-verified reads → Corrupted) + `FilesServiceImpl` in
manager-core. Metadata in Postgres (0018), bytes on disk under
PICLOUD_FILES_ROOT with 0o700 shard dirs.
- `files:*` trigger kind via the Layout-E pattern (0019: widen both
CHECKs + files_trigger_details), TriggerEvent::Files (metadata only,
no bytes), emit_files fan-out, dispatcher arm, admin endpoint
POST /triggers/files (reuses validate_trigger_target).
- AppFilesRead/AppFilesWrite capabilities → script:read/script:write
(seven-scope commitment held). AppPubsubPublish reserved for v1.1.6.
- Admin files API (list + delete) + dashboard Files view per app.
Cross-app isolation keyed on cx.app_id at every layer. ~45 new tests
(service in-memory, fs tempdir, bridge integration). No DB required
for the suite. publish_ephemeral and the orphan sweep stay deferred.

HTTP (`http::*`):
- `HttpService` trait (picloud-shared) + reqwest-backed `HttpServiceImpl`
(manager-core), wired into the `Services` bundle.
- SSRF deny-list applied to the resolved IP via a custom reqwest
`dns_resolver` (covers every redirect hop + defeats DNS rebinding) plus
a literal-IP check at URL-parse time. Scheme/port restrictions, request
+ response body caps (stream-with-cap), layered timeout. Error reason is
a CIDR category, never the IP. `PICLOUD_HTTP_ALLOW_PRIVATE` dev override
(logs a startup warning).
- Rhai bridge with three-arg split `verb(url, body, opts)` (resolves the
brief's body-vs-opts contradiction; unknown opt keys throw). Body
dispatch by type; response `#{status,headers,body,body_raw}` with JSON
auto-parse; non-2xx does not throw.
- `Capability::AppHttpRequest` → existing `script:write` scope (no new
Scope variant). `SdkCallCx` gains `script_id` (attribution + User-Agent).
Cron triggers (4th trigger kind):
- Migration 0017 widens the kind/source_kind CHECKs and adds
`cron_trigger_details`. `cron`/`chrono-tz` parse + validate 6-field
schedules and IANA timezones.
- `spawn_cron_scheduler` polls due triggers and enqueues to the universal
outbox; the dispatcher delivers them (one-line match-arm extension).
Catch-up fires exactly once per trigger per tick, not once per missed
window. `ctx.event.cron` for handlers.
- `POST /api/v1/admin/apps/{id}/triggers/cron` reuses the v1.1.3
cross-app + kind!=module target check.
- Dashboard: admin-gated Triggers tab (cron create form + list).
Follow-ups: redact module backend errors at the resolver boundary (log
original at error level); pin `rhai = "=1.24"`; CHANGELOG incl. retroactive
v1.1.3 cross-app-trigger security note. Version bumps: workspace 1.1.4,
SDK 1.5, dashboard 0.10.0.

Migrations 0013_docs.sql + 0014_docs_triggers.sql land the docs table
(JSONB body + GIN-on-jsonb_path_ops index, PK keyed on (app_id,
collection, id) for cross-app isolation) and widen the triggers.kind
and outbox.source_kind CHECK constraints to include 'docs', plus the
docs_trigger_details detail table mirroring kv_trigger_details.
picloud-shared grows the DocsService trait + DocRow/DocsListPage/
DocsError + NoopDocsService, the TriggerEvent::Docs variant with the
prev_data change-data-capture surface, the DocsEventOp enum, the docs
field on the Services bundle, and the SDK_VERSION bump 1.2 -> 1.3.

Wires the KV store into Rhai scripts via the handle pattern:
let widgets = kv::collection("widgets");
widgets.set("k", #{ n: 1 });
let v = widgets.get("k"); // value or () if absent
widgets.has("k") / widgets.delete("k")
let page = widgets.list(); // cursor-style pagination
`KvHandle` is a custom Rhai type holding `Arc<dyn KvService>` + the
per-call `Arc<SdkCallCx>`. Methods route async service calls through
`tokio::Handle::current().block_on(...)` — works because
`LocalExecutorClient` runs the script under `spawn_blocking` so a
runtime is reachable. The bridge surfaces `app_id` exclusively
through `cx.app_id`; no public-facing argument can spoof an app.
`TriggerEvent` lands in `picloud-shared` as the wire shape the
dispatcher will emit (KV + DeadLetter variants — KV exercised now,
DL hooks up with the dispatcher in commit 5/8). `SdkCallCx` and
`ExecRequest` grow `is_dead_letter_handler: bool` and
`event: Option<TriggerEvent>`. `engine.rs::build_ctx_map` flattens
the event into `ctx.event` for triggered handlers; direct ingress
leaves the key absent so scripts can `if "event" in ctx`.
Tests:
- 7 `sdk_kv.rs` integration tests covering the full Rhai surface
(round-trip, missing-key unit, has bool, delete was-present,
empty-collection rejection, cursor pagination, cross-app
isolation through the bridge).
- 3 new `engine.rs` tests pinning `ctx.event` shape per
design notes §4 (KV insert with value, delete with unit value,
direct invocations have no `event` key).
