After pressing Stop, SDK callers keep camera, microphone and screen capture active while the recording uploads. Capture now releases after the encoder delivers its final data, before video creation or multipart upload, without discarding recording chunks.

Closes #3190.

Same recording with video creation held pending	Before	After
Camera and microphone tracks at 150 ms and 1 s	live	ended
Paused recording stopped before upload	Capture remains live	Capture ended
Screen, system audio and microphone tracks	live	ended
Successful uploaded bytes	All emitted chunks	All emitted chunks

The existing encoder identity also protects a replacement recording when an old stop finishes after destroy/restart. The canceled stop rejects with AbortError before releasing tracks or uploading; stale data and source-ended callbacks cannot affect the replacement. Normal duration, upload results and errors retain their existing behavior.

All 35 SDK tests pass, including the capture-release and delayed-stop regressions. The suite now runs in CI. Independent Astra HIGH review approved the final patch and passed five additional ownership/error probes. Ten fresh native Chromium runs compare the original base and final runtime; all eight successful recordings preserve their complete emitted bytes and decode cleanly. Delayed-stop cancellation is verified with controlled encoder events.

Scoped TypeScript retains the pre-existing unsubscribe TS2345. Biome and tsup are unavailable locally; the exact CI formatting correction is included. Final-head configured CI passes, including the 35-test SDK suite, repository typechecking, Biome format/lint, Mobile, Linux Rust tests, both Clippy jobs and the native desktop build matrix. Current-head Greptile is 5/5 with no unresolved findings. Vercel previews require team authorization. Physical devices, OS indicators, Firefox/Safari, mounted React, authenticated storage and the published tsup package were not tested. Destroy/restart after upload has already begun remains a separately reproduced pre-existing limitation.

Confidence Score: 5/5

The PR appears safe to merge; the previous replacement-recording issue is fixed, and no new actionable issues were found.

Summary

Capture now ends after the encoder finishes and before upload begins.

• Stopping a recording ends capture before the upload begins.
• A delayed stop cannot interrupt a replacement recording.

@greptileai review current head d937565. The session-ownership P1 is corrected, including stale chunk/source callbacks and cancellation before upload. Three delayed-stop regressions fail on the previous revision; all 35 SDK tests pass. Astra HIGH R3 approved the exact head and five boundary probes. The prior Biome correction is also included; fresh CI is running.
