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.

Lays down the v1.1.3 plumbing:
- `ScriptKind` enum in `picloud-shared` ('endpoint' | 'module').
- `ModuleSource` trait + `ModuleScript` DTO + `NoopModuleSource` in
`picloud-shared`. Resolver lives in `executor-core`; Postgres impl
in `manager-core` (`PostgresModuleSource`).
- `Services::new` grows a fifth `modules: Arc<dyn ModuleSource>` arg.
- `ScriptValidator` returns `ValidatedScript { imports }` so the
manager can populate the dep-graph table on save. New
`validate_module` method on the trait gates module-shape rules.
- `Engine::execute_ast(&Arc<rhai::AST>, req)` lets the orchestrator's
script cache reuse compiled ASTs. `Engine::execute(&str, req)` is
preserved as a convenience that compiles inline. `Engine::compile`
exposes the AST for callers that want to cache.
- `PicloudModuleResolver` replaces `DummyModuleResolver` per-call.
Bridges Rhai's sync `ModuleResolver::resolve` to async
`ModuleSource::lookup` via `Handle::block_on`. Enforces:
- cross-app isolation (resolver captures `Arc<SdkCallCx>`),
- circular import detection (in-progress stack on the resolver),
- import depth limit (default 8 via
`Limits::module_import_depth_max`).
- Module-shape validation walks `ast.statements()` via `rhai/internals`
and accepts only `Var { CONSTANT }`, `Import`, and `Noop`. The
manager admin endpoint runs `validate_module` at save (primary
gate); resolver re-runs it at load (defense in depth).
- LRU cache `(AppId, name) -> (updated_at, Arc<Module>)` owned by
`Engine`. Size from `PICLOUD_MODULE_CACHE_SIZE` (default 512).
- Migration `0015_scripts_kind.sql` adds `scripts.kind` + composite
index + module-name shape CHECK.
- Migration `0016_script_imports.sql` adds the dep-graph table with
FK CASCADE on both columns.
- Repo: `kind` threaded through SELECT/INSERT/UPDATE. New
`count_routes_for_script` / `count_triggers_for_script` /
`list_imports` methods. `create`/`update` open a transaction and
call `replace_imports_tx` to populate the dep-graph.
- Admin endpoint: accepts `kind`; rejects reserved module names;
rejects `endpoint → module` transitions when routes / triggers
exist.
- SDK_VERSION 1.3 → 1.4.
Workspace builds; full test suite (~440 tests) green.

The docs:: SDK bridge mirrors kv::'s collection-handle pattern: a
custom Rhai type DocsHandle captures (collection, service, cx) once
via docs::collection(name), and methods bind via engine.register_fn
so scripts use dot-notation (users.create(...), users.find(...),
etc.). app_id never appears in the script-visible call shape — the
service derives it from cx.app_id, preserving cross-app isolation.
Methods registered: create, get, find, find_one, update, delete,
list (zero-arg and one-arg map-shaped overloads). The find filter
goes through dynamic_to_json -> DocsService::find -> docs_filter
parser; unsupported operators surface to Rhai with the parser's
verbatim error message (including the v1.2 pointer).
The doc envelope per Decision D:
#{ id: "uuid", data: #{...user data...},
created_at: "ISO-8601", updated_at: "ISO-8601" }
engine.rs trigger_event_to_dynamic gains a Docs arm that builds
ctx.event.docs = #{ collection, id, data, prev_data } where data
and prev_data follow the variant's Option<Value> -> () | map shape.
15 bridge integration tests under tests/sdk_docs.rs exercise the
round-trip via tokio::task::spawn_blocking. Covers create/get/find/
find_one/update/delete/list semantics, $in + $gt operators, the
unsupported-operator throw with v1.2 pointer, invalid-UUID rejection
on get/update/delete, the doc envelope's shape (id is string, data
is map, timestamps are strings), and the load-bearing cross-app
isolation guarantee. sdk_kv.rs is updated to take the new docs
field on Services::new.
