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).

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.

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.
