feat(extension): forward through the shared QueueDrainer - #10
Merged
Merged
Conversation
The extension ran its own copy of the delivery loop, which had drifted from the dashboard tab's: it skipped past an event another executor held (so newer webhooks overtook it, and nothing re-woke the loop when that claim went stale), and it treated a report the relay refused as delivered (so the event was forwarded again later). drain.js is now generated from apps/web/src/lib/drain.ts and imported by the module service worker, so the tab and the extension run one algorithm: stop at a foreign-held event and look again in 15s, re-send a refused answer instead of the webhook, shrink oversize answers on 413/431, skip the report when the claim was lost, record a timed-out handler once instead of re-running it. drain.test.mjs fails if the committed drain.js is stale. The live stream (/api/me/stream) also accepts the device token, so a paired extension gets push delivery without a dashboard session instead of falling back to polling.

Reviewer's GuideThe extension now delegates ordered webhook delivery to a generated copy of the dashboard’s shared QueueDrainer, aligning claim, retry, timeout, outage, and reporting behavior across executors. It also enables device-token SSE delivery and hardens response reporting against relay size limits, with build tooling and drift coverage protecting the generated implementation.

Merge Risk: 🟡 Moderate · up to Restarting a bridge while a webhook is being forwarded can deliver that webhook twice. It can also drop an answer the extension still owes the relay. Preserve the delivery state across restarts before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- Around line 973-974: Update startBridge and the QueueDrainer replacement flow
to preserve handled, attempts, and unreported state across restarts; await the
stopped drainer’s in-flight wake() before creating its replacement, or reuse
service-scoped state while creating a restartable drainer. Ensure the
replacement cannot reclaim events while prior forwards or reports are still
pending.

Review follow-ups on PR #10: - Chrome stops an extension service worker when a fetch() response takes more than 30s, so the 5-minute localhost timeout could never fire and a slow handler was re-sent after every restart. The extension now times out at 25s, and keeps forwards in flight in chrome.storage.session: an event whose forward was cut off is recorded once as a timeout instead of being sent again. The dashboard tab keeps its 5 minutes; the docs say so. - Toggling a service off and on mid-forward no longer sends the webhook twice: the new drainer waits for the previous pass. - A stopped bridge no longer writes its status; retries and refused reports show in the popup again; a restart clears the down flag so the next outage notifies. - The live stream restarts when the signed-in user changes. - CI gains a test job (relay, drainer, extension drift guard). Also refreshes CLAUDE.md: current architecture, local deploy steps, and where the brand tokens and logo live.
