fix(conciv,ui-kit-chat): a sent message never comes back as a draft - #531
Conversation
…sage never returns A draft write pending in a debounce timer outlived the send: the composer clear travelled through two 300ms debounces (composer persistence, then the pane draft storage), so the write carrying the sent text landed after the server deleted the row on send, and a pane mounted in the next few hundred ms restored the sent text into the composer. Both layers now write a cleared draft immediately and cancel anything pending, so no write carrying the sent text can be in the pipeline once the composer clears.

30-34: 📐 Maintainability & Code Quality | 🔵 Trivial | 🏗️ Heavy liftAdd a test for an RPC write already in flight.
The 350 ms wait starts the composer write at about 300 ms, but the pane debounce cannot fire until about 600 ms. This test covers cancellation of pending pane work. It does not cover the unresolved case where
rpc.drafts.sethas already started before send.Hold a pre-send draft-save request open, send the message, then release that request after the server clear. Assert that the persisted draft remains empty.

Limit the release note to pending writes.
The implementation cancels pending writes, but it does not fence an already-started persistence write. Replace “can never” with wording that describes immediate clears and cancellation of pending writes.

Use toHaveValue('') for the composer assertion.
The composer renders a <textarea>. toHaveText('') does not check its current value.

A clear that empties an already-empty draft now writes nothing at either hop, so a pane mounting with an empty composer no longer issues an rpc draft write on every mount. The transport reprobe test used to reach its unreachable-engine state through that incidental draft traffic: under fetch transport the widget only learns the engine is gone when a call fails, and the post-send draft clear happened to land after the rpc hold. It now types into the composer after the hold, so the call it depends on is one the test causes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

A message you just sent can reappear in the composer if the panel reloads right after the send. Found while investigating a CI failure in
remount.it.test.ts; reproduced deterministically on unmodifiedmain.Root cause — a lost update, not a lost timer
The trace showed the duplicate text is not a second transcript (there is exactly one
data-conciv-root); it is the composer, repopulated with the sent text.Two facts drive it:
packages/core/src/chat/run.ts:497deletes the row.AsyncDebouncerinuse-composer-draft.tsin front ofWebStorage.setItem, and another indraft-storage.tsin front of the RPC.Timeline on unmodified
main(ms from composer fill, pollingrpc.drafts.get):The stale row exists for ~530 ms. Any pane mounting in that window restores the sent text. On CI the send click took 831 ms, putting it inside the window — which is why CI caught it and a dev machine does not (locally fill→send is ~3 ms, so both writes coalesce into a single trailing write of
''and the row never holds the text).The fix
One rule applied at both hops: a clear is never debounced, and it cancels anything pending. Once the composer empties, no write carrying the sent text exists anywhere in the pipeline.
draft-storage.tsmoves from the baredebounce()helper tonew Debouncer(thenavigation-storage.tsidiom) because the helper returns a bare function with nocancel/flush.Debouncing exists to avoid a write per keystroke; clearing has no keystroke pressure, so it loses nothing.
Explicitly not done: a teardown
dispose()flush. That would push the stale text out after the server's delete and make the bug more likely, not less.What remains open
drafts.setcarries no monotonic stamp (unlikenavigation.set'supdatedAt), so a write already in flight when the server deletes can still land afterwards. Closing that needs a contract change and is not attempted here. The window goes from "a full debounce chain, ~530 ms, deterministic" to "an in-flight round trip that must overlap the delete".Coverage
draft-send-remount.it.test.tsdrives the real widget: fill, pause past the first debounce, send, reload, assert the composer is empty and the text appears exactly once. The reload is timed off observed server state rather than a wall-clock guess.Revert-check: reverting both files puts it red with the CI failure shape (
toHaveText('')receiving the sent text); restored,--repeat-each=3green. A pane-only fix also goes red — the clear does not reach that layer until the ui-kit debounce elapses, which is why both hops are touched.remount.it.test.tsstays green. Full embed suite:103 passed.🤖 Generated with Claude Code
