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.

Audit of feat/v1.1.4-http-cron against the v1.1.4 dispatch prompt.
All gates green on HEAD; 427 tests pass (+69 new), 140 ignored.
SSRF policy audited line-by-line: DNS-rebinding defense via reqwest
dns_resolver, literal-IP gap closed at validate_url on every redirect
hop, IPv4-mapped IPv6 re-check, IP never leaked in error strings.
Cron scheduler's fire-once catch-up policy verified; transactional
outbox-insert + last_fired_at bump.
Two flagged divergences accepted: three-arg verb(url, body, opts)
HTTP shape (resolves a self-contradiction in the brief; body_raw
dropped because raw strings just use positional body), and stale
schema-snapshot golden re-blessed (pre-existing drift from v1.1.1-
v1.1.3 — recommend lifting #[ignore] with CI DB in v1.1.5).
Three v1.1.3 follow-ups landed: module backend error redaction,
rhai = "=1.24" exact pin, retroactive CHANGELOG security note.
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.

Audit of feat/v1.1.3-modules against the v1.1.3 dispatch prompt.
All three gates green on HEAD; 358 tests pass, 140 properly ignored.
Cross-app isolation in PicloudModuleResolver verified airtight,
RAII guard pattern for stack+depth cleanup audited line-by-line,
version-keyed cache invalidation model accepted as correct.
Three deviations from the prompt reviewed: depth-limit default 8
instead of 32 (silent change — discipline note for next retro,
but the choice is defensible), module-name CHECK and reserved-name
list (both net improvements not in the prompt), ScriptValidator
trait shape change (bounded blast radius, required by dep-graph
design).
Latent cross-app security gap in v1.1.1/v1.1.2 trigger creation
closed as part of this release — backport awareness flagged for
the retro.
- Workspace `1.1.2` → `1.1.3` (`Cargo.toml`).
- Dashboard `0.8.0` → `0.9.0` (`package.json`).
- CHANGELOG: full v1.1.3 entry covering ScriptKind, ModuleSource,
PicloudModuleResolver, the two caches, dep-graph table, route +
trigger module rejection, the latent cross-app trigger gap that
this release closes, migrations 0015/0016, and downgrade caveats.
- Blueprint: mark the "Can scripts `import` Rhai modules?" question
as resolved; one-line pointer to the v1.1.3 semantics.

- `Script` type gains `kind: 'endpoint' | 'module'`. `CreateScriptInput`
+ `UpdateScriptInput` carry an optional `kind` field.
- App page's script-create form grows a kind dropdown next to Name +
Description. Selecting "module" surfaces a hint that modules cannot
bind to routes / triggers.
- Scripts list renders a small badge after the version: blue
"endpoint" or purple "module".
- Script detail page renders the same badge next to the H1.
`npm run check` passes (0 errors, 0 warnings).

- New `ScriptIdentity { script_id, updated_at }` DTO.
- `ExecutorClient` trait gains an `execute_with_identity` method;
default impl forwards to `execute` so `RemoteExecutorClient` (and
cluster-mode transports later) keep working without bespoke caching.
- `LocalExecutorClient` overrides `execute_with_identity` to consult
an `LruCache<ScriptId, CachedScript>`. Cache hit only when the
cached entry's `updated_at` matches the caller's identity; mismatch
triggers a fresh `Engine::compile`. `Engine::execute_ast(&Arc<AST>, req)`
is called inside `spawn_blocking` exactly as `execute` does today.
- Cache size from `PICLOUD_SCRIPT_CACHE_SIZE` (default 256).
- Orchestrator's HTTP data-plane path and the dispatcher both switch
to `execute_with_identity`. `ResolvedTrigger` carries
`script_updated_at` for the dispatcher's identity construction.
Workspace builds; full test suite (~440 tests) green.

- `POST /api/v1/admin/scripts/{id}/routes` returns 400 when the
target script is `kind=module`. Modules have no entry point — they
are imported, not invoked.
- `POST /api/v1/admin/apps/{id}/triggers/{kv,docs,dead_letter}` gain
a shared `validate_trigger_target` that loads the target script
and rejects when:
- the script doesn't exist
- the script belongs to a different app (latent v1.1.1/v1.1.2 gap
where triggers could target a script in any app — closed here)
- the script is `kind=module`
- `TriggersState` grows a `scripts: Arc<dyn ScriptRepository>` field
so handlers can load the target script.
- Trigger-create test helpers split into `state_with` (empty script
repo — for tests asserting upstream errors) and
`state_with_endpoint` (pre-populated — for tests asserting
successful creation). `InMemoryScriptRepo` added to the test
module.
Workspace builds; full test suite (~440 tests) green.

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.

Independent audit of feat/v1.1.2-documents over two iterations.
Iteration 1 returned for a single-line cargo-fmt fix that HANDBACK
had falsely claimed was green. Iteration 2 (bf26a25 + fedc63b)
applied the fix, re-verified all three gates on the new HEAD, and
recorded the discipline lesson in HANDBACK §1 for the v1.1.3 retro.
Re-audit on iteration-2 HEAD: fmt + clippy + 320-test workspace all
green. SQL builder is parameter-bound end-to-end (audited line-by-line
in docs_repo.rs:319-420 with adversarial-input tests). Layout E
extension for docs is mechanically clean. Query DSL operator set
is correct precedent for v1.2's advanced-query expansion.
Branch ready to merge as v1.1.2.
Iteration 2: the v1 HANDBACK §8 claimed `cargo fmt --check` was
green against HEAD; the reviewer correctly caught that as false. The
sibling `chore: cargo fmt` commit (bf26a25) fixed the diff. This
commit updates §8 to replace the false claim with a table of actual
exit codes + test counts I re-ran post-fix, plus a §1 note
explaining the iteration so the audit trail is honest.
No code changes. Only HANDBACK.md.

Single-line collapse in DocsServiceImpl::delete's $in match arm
flagged by `cargo fmt --check` post-review. The v1 HANDBACK §8
claimed `cargo fmt --check` was green; that claim was false against
HEAD at audit time. This fixes the diff so all three gates exit 0
on a fresh checkout. The follow-up HANDBACK update replaces §8's
false attestation with a post-fix one.

Replaces the v1.1.1 HANDBACK (its release record is preserved on

Workspace package version 1.1.1 -> 1.1.2; dashboard 0.7.0 -> 0.8.0
(workspace alignment, no docs-specific UI yet); SDK_VERSION
1.2 -> 1.3 for the docs:: surface + ctx.event.docs additions.
CHANGELOG entry documents the docs store, the query DSL subset, the
docs:* trigger kind, the prev_data change-data-capture surface, and
the new AppDocsRead/AppDocsWrite capabilities. Includes a downgrade
caveat (v1.1.2 -> v1.1.1 with queued docs outbox rows would fail
TriggerEvent deserialization) and known-limitations notes for the
text-lex comparison gotcha and the concurrent-update prev_data race.

build_app constructs PostgresDocsRepo + DocsServiceImpl alongside
the existing KV wiring, sharing the same OutboxEventEmitter so KV
and docs mutations both fan out through the same dispatcher. The
docs handle joins the Services bundle so executor-core sees it on
every per-call sdk::register_all.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The docs trigger kind hangs off the same Layout-E shape that v1.1.1
established for KV: a parent triggers row + a docs_trigger_details
row (collection_glob TEXT + ops TEXT[]) with the empty-array =
any-op semantic preserved.
- trigger_repo.rs adds TriggerKind::Docs + TriggerDetails::Docs +
CreateDocsTrigger + DocsTriggerMatch + PostgresTriggerRepo
implementations of create_docs_trigger and list_matching_docs.
list_matching_docs mirrors KV's Rust-side filter (does NOT push
ops membership into SQL — that would exclude empty-ops rows).
- outbox_repo.rs adds OutboxSourceKind::Docs to the enum + wire form.
- dispatcher.rs's generic Kv | DeadLetter routing arm extends to
Kv | DeadLetter | Docs. No kind-specific logic needed — the
resolve_trigger + build_exec_request path is already abstract.
- outbox_event_emitter.rs gains a "docs" arm in the emit match plus
emit_docs which builds TriggerEvent::Docs (carrying data +
prev_data) and fans out across matching triggers.
- triggers_api.rs adds CreateDocsTriggerRequest + create_docs_trigger
+ the POST /api/v1/admin/apps/{id}/triggers/docs route, all
guarded by Capability::AppManageTriggers (same as KV).
3 new triggers_api unit tests covering happy path, empty-glob
rejection, and capability denial. All existing trigger-related
tests still pass.

DocsServiceImpl mirrors KvServiceImpl's script-as-gate authz pattern,
the empty-collection rejection, and the best-effort emitter call —
adding "data must be a JSON object" validation, NotFound on update of
a missing doc, and prev_data plumbing via repo.update returning the
prior data.
PostgresDocsRepo handles CRUD against the docs table. The find path
runs through the v1.1.2 query DSL parser (docs_filter::parse_filter)
before building parameterised SQL via sqlx::QueryBuilder:
* Every field-path segment + comparison value is bound as $N.
* jsonb_extract_path_text(data, $N1, $N2, ...) handles variable
depth without segment interpolation.
* Base WHERE is fixed: WHERE app_id = $1 AND collection = $2.
Filter conditions can only narrow, never widen. Load-bearing
test in sql_shape_tests pins this prefix on every emitted query
+ asserts no user string ever lands in the SQL text.
* $ne uses IS DISTINCT FROM (not <>) so missing paths + JSON nulls
are correctly included.
* $in binds the value list as TEXT[] via = ANY($N::text[]).
* $sort always appends a ", id ASC" tiebreaker for stable cursor
pagination semantics; $limit is clamped to MAX_FIND_LIMIT.
docs_filter is the AST + parser for the DSL. Operator allowlist is
explicit; any non-v1.1.2 operator throws UnsupportedOperator with a
v1.2 pointer. Snapshot tests pin the SDK-contract error strings so
changing them is a deliberate act.
Two new Capability variants — AppDocsRead and AppDocsWrite — map to
the existing Scope::ScriptRead and ScriptWrite per the seven-scope
commitment from v1.1.0. role_satisfies grants read at Viewer,
write at Editor (same trust shape as KV).
59 unit tests added across the three new files. All pass.

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.

The "don't reach across *-core crates" rule was being read as
prohibiting any cross-crate import, but the load-bearing intent is
to keep *behavior* decoupled (so cluster-mode can swap implementations
behind traits in shared). Importing transport DTOs across crates is
fine — ExecRequest/ExecResponse/ExecError live in executor-core
because that's where they're produced, and the v1.1.1 dispatcher in
manager-core legitimately consumes them.
Bright line: structs/enums/type-aliases crossing is fine; traits,
functions, and service handles crossing is not.
Surfaced during the v1.1.1 audit (see REVIEW.md §4).
Independent audit of feat/v1.1.1-storage-and-events against the
design notes §1–4 (Decided 2026-06-01) and the original dispatch
prompt. Static checks reproduce green; 243-test workspace suite
passes; schema + dispatcher + inbox conform to the design notes
end-to-end. Nine HANDBACK-flagged deviations reviewed individually
and accepted. One ambient concern (manager-core → executor-core
DTO dependency) flagged for a small CLAUDE.md clarification
post-merge; not a merge blocker.
- Workspace package version: 1.1.0 → 1.1.1 (patch under the
post-1.0 expansion-phase carve-out in docs/versioning.md)
- Rhai SDK version: 1.1 → 1.2 — minor bump, additive only.
New surfaces: kv::*, dead_letters::*, ctx.event.
- Dashboard package version: 0.6.0 → 0.7.0 for the dead-letters UI.
- HTTP API version stays at 1 (additive: trigger CRUD, dead-letter
admin endpoints, dispatch_mode field on routes).
- Schema version: 6 → 12 (migrations 0007–0012).
CHANGELOG.md created at the repo root following the convention from
prior bumps (release commits + design-notes references).

Two tokio tasks spawned at startup that sweep their respective
tables on a weekly cadence (design notes §3 #9 + §4 retention).
Both use `FOR UPDATE SKIP LOCKED` on the claim query so concurrent
sweepers in cluster mode (v1.3+) don't fight each other.
Defaults: 30 days for dead_letters, 7 days for abandoned_executions.
Both env-overridable via `PICLOUD_DEAD_LETTER_RETENTION_DAYS` and
`PICLOUD_ABANDONED_EXECUTIONS_RETENTION_DAYS` (loaded into
`TriggerConfig::from_env` from commit 5).
Per-tick batch cap (5_000 rows) so a sweep can't lock up the table
in a single transaction; the inner loop continues until 0 rows
affected, after which the outer tick waits for the next week.

Design notes §4 makes the dashboard surface load-bearing — with no
default DL handler, users wouldn't know dead letters exist
otherwise.
New route: `apps/[slug]/dead-letters/+page.svelte` — list view
columns per the design notes:
- `created_at`, `source`, `op`, `script_id`, `attempt_count`,
`first/last_attempt_at`, `last_error` (truncated; clickable)
- per-row Replay + Mark resolved buttons
- expandable row detail panel showing full payload (JSON) +
full last_error
- unresolved-only filter (default on); refresh button
Per-app detail page (`apps/[slug]/+page.svelte`) grows a "Dead
letters" link in the tabs nav, with a red unresolved-count pill
when > 0. Loaded in parallel with the existing app loaders so it
doesn't slow the page.
Apps list (`apps/+page.svelte`) shows the same red pill next to
each app's name when its unresolved count > 0. Counts fetched in
parallel after the apps list lands; failures here are non-fatal
(just no badge).
API client wiring: `api.deadLetters.{count,list,get,replay,resolve}`
mirrors the v1.1.1 admin endpoints. `DeadLetterRow` type added to
the dashboard's API shape declarations.
dashboard's svelte-check passes (369 files, 0 errors, 0 warnings).

`PostgresDeadLetterService` lands as the real `DeadLetterService`
impl, replacing `NoopDeadLetterService` in the picloud binary's
`Services` bundle. Both methods are gated by
`Capability::AppDeadLetterManage(AppId)` — public-HTTP scripts with
`principal: None` fail the check, per design notes §4.
- `dead_letters::replay(id)` (Rhai SDK + admin endpoint): re-inserts
the original event payload into the outbox with attempt_count=0,
reply_to=None. The DL row is marked `resolution='replayed'`.
- `dead_letters::resolve(id, reason)` (Rhai SDK + admin endpoint):
closes the row with `resolved_at = NOW()` and the given reason.
CHECK constraint on the column enforces the 4-value vocabulary.
- `dead_letters::list(filter)` is intentionally NOT shipped —
design notes §4 defers it to v1.2 to align with the eventual
`docs::find()` query DSL.
Admin endpoints under `/api/v1/admin/apps/{id}/dead_letters/*`:
- `GET /` (with `?unresolved=true`) → list view
- `GET /count` → unresolved-count badge
- `GET /{dl_id}` → row detail (full payload + error)
- `POST /{dl_id}/replay` → re-enqueue
- `POST /{dl_id}/resolve` body `{reason}` → close out
All cross-app-aware: the row's `app_id` is compared against the path
param so a caller with rights on app A cannot manipulate app B's
dead letters by id alone.
The Rhai bridge for `dead_letters::*` follows the same sync↔async
pattern as the `kv::` bridge (`Handle::current().block_on(...)`
inside the spawn_blocking-wrapped Rhai engine).

Routes gain `dispatch_mode TEXT NOT NULL DEFAULT 'sync'` (migration
0012). Existing routes default to sync so the migration is
non-breaking. `DispatchMode` enum lands in `picloud-shared`.
The user-routes orchestrator handler now branches:
- `dispatch_mode = async` → write outbox row with `reply_to = None`,
return `202 Accepted` + `{accepted_at, execution_id}`. Dispatcher
fires the script in the background; retries / dead-letters via
the framework from commit 5.
- `dispatch_mode = sync` → register an inbox channel
(`tokio::sync::oneshot`), write outbox row with `reply_to =
inbox_id`, `.await` on the receiver with a timeout =
script.timeout_seconds + 2s buffer. Dispatcher hands the result
back; orchestrator maps `InboxResult` into the HTTP response per
the design-notes §3 status-code table (422/502/503/504/507/500).
`InboxRegistry` (orchestrator-core/src/inbox.rs) is the in-process
implementation of `InboxResolver`. Lock-free HashMap of pending
oneshot senders keyed by `inbox_id`. Tests cover register/deliver
round-trip, unknown-id is abandoned, dropped-receiver is abandoned,
explicit cancel. Cluster mode (v1.3+) swaps this for
LISTEN/NOTIFY-keyed lookup behind the same trait.
`OutboxWriter` trait lives in `picloud-shared` so orchestrator-core
can write to the outbox without depending on manager-core (which
would invert the dependency arrow). `PostgresOutboxRepo` implements
both `OutboxRepo` (dispatcher surface) and `OutboxWriter`
(orchestrator surface); the picloud binary clones the same concrete
Arc into both trait views.
The dispatcher's HTTP arm (commit 5 had a stub) now decodes the
`HttpDispatchPayload` off the outbox row, looks up the script,
synthesizes an `ExecRequest`, and runs it through the executor.
Outcome routing reuses the same path as KV triggers — sync HTTP
flows through the inbox, async dispatch gets dropped after
success (or DL'd on exhaustion).

`OutboxEventEmitter` replaces `NoopEventEmitter` in the picloud
binary's `Services` bundle. KV mutations now fan out to the outbox
via `TriggerRepo::list_matching_kv` — one row per matching trigger,
carrying the serialized `TriggerEvent` payload + the matching
trigger's retry policy.
`Dispatcher` is the single tokio task that polls the outbox every
100ms, claims due rows via FOR UPDATE SKIP LOCKED (with a batch cap),
and routes each to the executor. Shares the `ExecutionGate` with
sync HTTP per design notes §2 — gate saturation reschedules the
row instead of dropping it.
Outcome handling matches design notes §3 and §4:
- reply_to.is_some() (sync HTTP): never retry. Deliver via
`InboxResolver`; if the receiver was dropped, write an
`abandoned_executions` row.
- is_dead_letter_handler == true: never retry, never DL. On
failure, annotate the original DL row with
`resolution = 'handler_failed'`. Stops the recursion that would
otherwise re-fire a broken handler script.
- Otherwise async: bump attempt_count, reschedule with exponential
backoff + ±jitter; once max_attempts is reached, write a
`dead_letters` row and drop from outbox.
- Trigger-depth limit: `cx.trigger_depth > max_trigger_depth` skips
execution entirely (log + future metric), NEVER dead-letters.
Loops are not retried via the DL chain — they're terminated.
`InboxResolver` trait lands in `picloud-shared` with a
`NoopInboxResolver` bootstrap that flags every delivery as
`Abandoned`. Commit 6 replaces the noop with the real
in-process registry in `orchestrator-core`.
`AdminPrincipalResolver` builds a `Principal` from a trigger's
`registered_by_principal` user id so the dispatched script executes
as the trigger registrant (design notes §4).
Unit tests cover backoff math (exponential/linear/constant) +
jitter range + ExecError → InboxFailureKind classification + the
status-code table mapping. Integration tests for the full
dispatcher loop need a real Postgres + executor; reviewer runs them
via the manual smoke flow in the plan / HANDBACK.

`/api/v1/admin/apps/{id}/triggers/*` — separate POST endpoints per
kind (kv / dead_letter) so each request validates against the
correct shape. List and DELETE work across both kinds.
Gated on `Capability::AppManageTriggers(app_id)`, which maps onto
`Scope::AppAdmin` (no new scope variants — seven-scope commitment
held) and is granted at the per-app `AppAdmin` role.
Request payloads accept `dispatch_mode` (defaults to `async`) and
retry-override fields. Omitted retry fields fall back to
`TriggerConfig::from_env`, which the binary plumbs into
`TriggersState` so the row is auditable from itself (no lazy
resolution at dispatch time). `registered_by_principal` is taken
from the authenticated principal — design notes §4: "a trigger
execution runs as the principal that registered the trigger".
DELETE loads the trigger first and 404s if its `app_id` doesn't
match the path — prevents a caller with rights on app A from
deleting a trigger via app B's path (bound-key safety net).
In-memory tests cover: app-not-found, member-without-role 403,
default-fallback for retry settings when request omits them,
empty-glob rejection, cross-app delete is treated as not-found.

Migrations 0008-0011 lay down the triggers framework's storage:
- `triggers` + `kv_trigger_details` + `dead_letter_trigger_details`
(Layout E, design notes §2). Parent table carries common columns
including `registered_by_principal` — the dispatcher uses this to
run the trigger as the user that registered it (design notes §4).
- `outbox`: universal async dispatch substrate. KV/cron/pubsub/queue/
email/dead-letter all write rows in the same shape; the dispatcher
claims due rows via FOR UPDATE SKIP LOCKED. `reply_to` is the
NATS-style inbox id for sync HTTP (commit 6) — its presence flags
"don't retry" per the design.
- `dead_letters`: exact schema from design notes §4 with the four-
value `resolution` CHECK constraint (`replayed | ignored |
handled_by_script | handler_failed`) and partial index on
unresolved rows for the dashboard badge.
- `abandoned_executions`: forensic table for the dispatcher's
"tried to resolve a dropped inbox" edge case (design notes §3 #9).
Repo surfaces with Postgres impls behind traits so unit tests can
swap in-memory backings:
- `TriggerRepo` — CRUD + the `list_matching_kv` /
`list_matching_dead_letter` hot paths the dispatcher uses.
Includes a `collection_matches` helper that handles `*`, `prefix:*`,
and exact-name globs.
- `OutboxRepo` — insert + claim-due + delete + reschedule.
- `DeadLetterRepo` — insert + get + list + unresolved-count +
resolve + GC.
- `AbandonedRepo` — insert + GC.
`TriggerConfig::from_env` (new module) follows the existing
`SandboxCeiling` env-loading pattern for `PICLOUD_MAX_TRIGGER_DEPTH`,
`PICLOUD_TRIGGER_RETRY_*`, `PICLOUD_DEAD_LETTER_RETENTION_DAYS`, and
`PICLOUD_ABANDONED_EXECUTIONS_RETENTION_DAYS`.
`Capability::AppManageTriggers(AppId)` and `AppDeadLetterManage(AppId)`
join the enum. Both map onto the existing `Scope::AppAdmin` per the
seven-scope commitment; `role_satisfies` grants them at the
`AppAdmin` per-app role.

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).

First v1.1.1 commit. Adds the KV store the design notes commit to:
`(app_id, collection, key)` identity with JSONB value and a per-app
index. Trait lives in `picloud-shared` so the executor-core Rhai
bridge (next commit), the Postgres impl, and tests all depend on the
same surface without coupling crates.
The `Services` bundle grows from empty to three fields: `kv`,
`dead_letters` (NoopDeadLetterService stub — replaced by the
Postgres impl in commit 8), and `events` (NoopEventEmitter until the
outbox emitter lands with the dispatcher). Tests use
`Services::default()` for an all-noop bundle.
New capabilities `AppKvRead` / `AppKvWrite` join the Capability
enum. They map onto the existing seven-value `Scope` (script:read /
script:write) — the scope vocabulary stays locked per the
`docs/versioning.md` commitment.
Script-as-gate semantics in `KvServiceImpl`: capability check runs
when `cx.principal.is_some()`, skipped when None (public HTTP).
Cross-app isolation is enforced independently by deriving every
row's `app_id` from `cx.app_id` rather than a script-passed argument.
In-memory `KvRepo` impl + unit tests cover the round-trips, the
cross-app isolation property, empty-collection rejection,
script-as-gate behaviour for both anonymous and authed contexts,
and cursor-style pagination. Postgres impl exists; integration
testing waits for a real DB harness (see HANDBACK).

Annotates the v1.1.x design notes with the resolutions for the 20 open
calls — pub/sub split, universal outbox, NATS-style sync HTTP, status
code strategy, retry policy, dead-letter recursion-stop, realtime
auth model, frontend client library scope. Captured ahead of the
v1.1.1 implementation so the schema + API decisions in this branch
have a single load-bearing source of truth.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Consolidates the architectural conversations that followed the v1.1.0
release but haven't yet landed in the blueprint or in code. Six topic
areas, each with status + open calls:
1. Messaging primitives — invoke vs pub/sub vs queue, recipient
model and delivery semantics
2. Universal trigger outbox — async dispatch substrate for every
event source (sync HTTP excepted, see #3)
3. NATS-style sync HTTP — per-request inbox + oneshot channel lets
sync HTTP ride the outbox without losing the response path
4. Dead-letter handling — separate table, dead_letter trigger kind,
recursion stop rule, retention defaults
5. Realtime updates — SSE-based external subscription to per-app
pub/sub topics with opt-in exposure
6. Frontend client library — hybrid model (TS lib that talks to
dev-defined script endpoints, not to services)
Plus a revised v1.1.x roadmap: realtime adds at v1.1.6 (was Config &
Email), shifting later items by one to v1.1.9 (was v1.1.8).
20 open calls consolidated at the bottom, numbered for reference.
Document is meant to be pruned as decisions ship; deleted entirely
when v1.1.9 lands.
No blueprint changes yet — those wait for the open calls to be
answered and the corresponding PRs to ship.

Rewrites the "When to bump what" section now that the project is
post-1.0. Replaces the pre-1.0 framing with three explicit rules:
- Major: surface major bump on a user-facing contract
- Minor: phase milestone or coherent capability cluster, aligned
with blueprint Phase boundaries (Phase 5 -> v1.2, etc.)
- Patch: bug fixes AND additive-only surface changes
The carve-out (patch for additive surface changes) resolves the
tension with the v1.1.x roadmap: every v1.1.x release adds SDK or
schema surface, and strict "minor product bump per minor surface
bump" would inflate the version faster than the user-perceived
"platform changed" milestones warrant.
Examples updated to reflect post-1.0 numbers and the new policy:
adding KV in v1.1.1 (patch), cutting v1.2 as a phase milestone
(minor), renaming a ctx field (major).

Aligns the Cargo package version with the blueprint roadmap labels.
v1.1.0 = SDK foundation (#0) + stdlib utilities (#0.5), the first
release of the Phase 4 / v1.1 series.
Also updates docs/versioning.md:
- Current versions table: Product 0.6.0 -> 1.1.0
- Docker / Git tag examples: 0.2.0 -> 1.1.0
Cargo.lock regenerated by `cargo check --workspace`.

A script author opening docs/stdlib-reference.md should see every
function they can call without imports: the Rhai built-in stdlib (math,
string, array, map, blob) plus the seven new PiCloud namespaces. Tight
tables over prose — scannable rather than exhaustive.
CLAUDE.md current-focus paragraph picks up a pointer to the new doc.

43 tests exercising one happy path and the major error paths per
module (invalid regex pattern, oversize random::bytes, malformed JSON,
bad base64, mixed-case hex round-trip, invalid UTF-8 in url::decode,
etc.). Harness duplicates the pattern from sdk_contract.rs — each
integration test file in this crate keeps its own; there is no
tests/common/.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds the v1.1.0 user-visible stdlib: regex, random, time, json, base64,
hex, url — each exposed as a `::` namespace mirroring the existing
`log::` pattern. Modules register once at engine build via
`Engine::register_static_module`, distinct from the stateful service
modules (KV, docs, …) that hook into `sdk::register_all` per call.
- regex: linear-time, compile-per-call (no cache by design)
- random: OsRng only; bytes/string capped to prevent script-side blow-up
- time: UTC, ms-since-epoch as canonical i64; RFC 3339 strings for I/O
- json: parse/stringify via existing dynamic<->json bridge
- base64: standard + URL-safe alphabets, Blob and String inputs
- hex: lowercase output, case-insensitive decode
- url: RFC 3986 percent-encoding + encode_query for Maps
Stdlib registration runs unconditionally — including in the parse-only
validate path — so scripts get a uniform surface in both phases.
See docs/sdk-shape.md for the stateless-vs-stateful distinction.

v1.1.0 PR #0 — SDK Foundation.
Lands the architectural shape every v1.1.x stateful service hangs off,
without shipping any user-visible service. After this PR, subsequent
service PRs (KV v1.1.1, docs v1.1.2, …) are mechanical fill-in:
- picloud_shared::{SdkCallCx, Services, ServiceEventEmitter +
NoopEventEmitter} lock the per-call context, service bundle,
and event-emission trait shape.
- executor-core::sdk/ — register_all hook called per invocation;
json↔dynamic bridge moved here from engine.rs.
- ExecRequest gained app_id, principal, trigger_depth,
root_execution_id (the last two reserved for v1.1.1's triggers
framework).
- orchestrator-core::gate::ExecutionGate — single global semaphore
(PICLOUD_MAX_CONCURRENT_EXECUTIONS, default 32). Overflow returns
503 + Retry-After: 1 immediately, no queue.
- manager-core::attach_principal_if_present — opportunistic,
fail-open middleware wired on data-plane + user-routes.
- docs/sdk-shape.md — developer-facing reference for the
conventions every future service PR implements against.
- Blueprint revisions: Phase 3.5 marked ✓ Shipped, §8.1 KV switched
from hstore to JSONB, new §7.5 SDK Architecture section and §7.5.1
trigger sketch, §12 Phase 4 restructured into v1.1.0 → v1.1.8.
- CLAUDE.md: current focus → v1.1.0, JSONB note, handle-pattern
Working Rule, Runtime Configuration table with the new env var.

Two review-pass nits from the v1.1.0-foundation review:
- Blueprint §6 Tech Stack table still listed the database as
"PostgreSQL + hstore" with an hstore-for-KV rationale — directly
contradicting the §8.1 KV rewrite that explicitly rejected hstore
in favour of JSONB. Updates the row so the high-level summary
matches the §8.1 reasoning.
- LocalExecutorClient::execute now documents the permit-vs-timeout
interaction: when tokio::time::timeout fires the future drops and
the permit returns, but the detached spawn_blocking thread keeps
running until the Rhai script winds down. In-use blocking threads
can briefly exceed the gate's permit count after a timeout. Calling
it out so future readers don't read the implementation as buggy.
No behaviour change.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- sdk/bridge.rs: drop #[must_use] on the bridge fns — `Dynamic` and
`serde_json::Value` are both #[must_use] already; the wrapper
attribute is double-must-use noise.
- api.rs IntoResponse: hoist `use ApiError as E;` above the early
Overloaded branch so `E::Exec(...)` works in the if-let too
(clippy::items_after_statements).
- gate.rs test: bind the returned permit with `let _ =` so the
OwnedSemaphorePermit doesn't trip unused-must-use.
No behaviour change. Caught by `cargo clippy --all-targets
--all-features -- -D warnings`.

- Current focus moves to v1.1.0 (SDK foundation + stdlib) with a
pointer to docs/sdk-shape.md. Notes Phase 3.5 capability gating is
shipped end-to-end.
- Tech-stack line drops the misleading "v1.1+ hstore" mention; v1.1+
data-plane tables now use JSONB (see blueprint §8.1).
- New Working Rules bullet for the handle pattern + SdkCallCx rule:
services derive app_id from cx.app_id, never from a script-passed
arg. That is the cross-app isolation boundary.
- New "Runtime configuration" table documenting every env var the
picloud binary consumes — including the new
PICLOUD_MAX_CONCURRENT_EXECUTIONS alongside the existing
PICLOUD_BIND, DATABASE_URL, session TTL, and sandbox knobs.

Lands the developer-facing reference for the SDK shape every v1.1.x
service implements against, plus the blueprint changes the shape and
the recently-shipped Phase 3.5 imply:
- New docs/sdk-shape.md — covers handle pattern, :: namespace,
throw/() error convention, sync↔async bridge, cross-app isolation
rule, ServiceEventEmitter, ExecutionGate + env var, stateless vs
stateful module registration.
- Blueprint §11.6 (Phase 3.5): Pending → ✓ Shipped, with a note that
it landed ahead of the originally planned slot.
- Blueprint §8.1 (KV Store): replace hstore schema + rationale with
JSONB. PK becomes (app_id, collection, key); cross-app isolation
is enforced at the index, not just the service layer. Note 64 KiB
per-value cap enforced at the service layer (lands with the KV PR
in v1.1.1).
- Blueprint new §7.5 (SDK Architecture): brief overview pointing to
docs/sdk-shape.md. Includes §7.5.1 sketch of the trigger
architecture (outbox + depth limit + (service, event, filter) →
script).
- Blueprint §12 Phase 4: restructured to enumerate v1.1.0 through
v1.1.8 with one focused capability per release. Current focus
moves to Phase 4 (v1.1.0) now that Phase 3.5 is done.
