1.5 applied cursor-dwell zooms when a take landed in the editor. Import still seeded a clip, but never ran that pass.
Serialize the apply/save, wait for a probed duration, and do not resurrect zooms after undo. System-cursor mode disables the control.
The serialized save lives on writeFreshRecordingAutoZooms; CI lint rejected the 100-col lines and the audit table still named the wrapper.
Lock the HUD control to the selected cursor mode, and collect suggestions only for the pending recording so a later import is not decorated.
Typecheck (tests) rejected the getPlatform mock returning string.
Wait for ordinary saveDocument calls to finish, then append zooms to whatever the store actually holds.
MediaRecorder WebMs still report NaN on load. Keep a 60s timeline clip so replaceTimeline has a duration to clamp against, but leave asset.durationSec unset until a real probe. Bind the queued metadata write to the project that owned the video, and cover Rec-stage auto-zoom next to the panel.
waitForDocumentSaves before the zoom write cannot see an edit that starts after that save is already in flight. Wait again after it returns, and only consume pending when the store still has the zooms.
…k save waitForDocumentSaves could park forever. saveDocument releases waiters from a finally, so a save that rejects is already covered, but a bridge call that never settles runs no finally at all: the in-flight counter stays above zero and the module-level auto-zoom chain wedges behind it for the life of the renderer. It now answers "idle" or "timeout", and every caller reads a timeout as "I do not know what landed" -- abandon the attempt, keep pending, let a retry run. Contention is an exit, not a rebase. Recomputing the suggestions onto the document another writer just produced only races that writer again, so the attempt is dropped with pending intact and the existing 500/1500/3000 ms retries run against a settled document instead. A system-cursor take is no longer marked pending. It writes no .cursor.json, so the flag stayed set for the life of the window while all three retries read an empty sidecar. What governs is the cursor mode the take was recorded in, not the preference at import time. Also log what reaches the outer catch, which was swallowing anything the suggestion pass threw, and drop applyFreshRecordingAutoZooms: an unused export that bypassed the pending, asset-path, project-id and duration checks. Both new behaviours are covered by tests that fail against the old code -- the contention exit writes zooms without it, and the stuck-save wait never returns.
The previous commit gave the waits a deadline but left the write that follows them unbounded, which is the same hang one level up. `saveDocument` awaits the bridge with no deadline of its own and, by contract, never rejects, so a main process that stops answering parks that await forever -- and it runs inside `freshRecordingAutoZoomSaveChain`, so the wedged write takes the chain with it and the 500/1500/3000 ms retries queue behind a promise that is not coming back. Race the write against a deadline instead. On expiry the attempt ends with pending still set and the chain moves on; abandoning the save is safe precisely because it cannot reject. Both deadlines are injectable so tests do not have to sit through the real one. The test is last in its file on purpose: its stuck save is never released, so it leaves the in-flight counter raised for anything that runs after it.

`handleLoadedMetadata` runs its work on a promise chain so a queued duration cannot land on the wrong project. That chain awaits `saveDocument`, and `saveDocument` awaits the bridge with no deadline of its own — so a main process that stops answering leaves the await pending forever and takes the chain with it: every later `loadedmetadata` and the auto-zoom pass behind it queue on a promise that is not coming back. Before the chain existed the write was fire-and-forget, so a wedged save cost one duration, not all of them. `saveWithDeadline` already existed for exactly this in the auto-zoom write. It moves next to `waitForDocumentSaves`, which is the same deadline seen from the other side — that one is for a caller queued behind a save, this one for the caller that started it. `saveDocument` never rejects, so the abandoned write is safe to let go of; on a timeout the handler carries on with whatever the store actually holds and auto-zoom's own guards decide what that is worth.
`replaceTimeline` pins the clip it builds to `primaryAssetId ?? assets[0]`, and the seed sizes that clip from the `loadedmetadata` event that triggered it. The two were never checked against each other, so an event from any other asset filed one video's length under another video's id. Reaching it takes a project whose first import was audio: audio never claims the empty primary slot (document-service.addAsset), so `assets[0]` is the audio track and the primary is the video added after it. With no clips to follow, the preview fell back to the whole asset list and VirtualPreview mounts index 0 — the audio. Both halves move together, because either alone is worse than neither. The guard alone would make the mounted asset fire an event the seed refuses, and since the source index only moves for clips, nothing else would ever be mounted and the timeline would stay empty for good. The preview change alone would leave the wrong-length clip reachable by any other route to a non-primary event. So: the seed accepts only its own asset, and the empty-timeline preview mounts that asset. The whole-list fallback stays for a primary id that resolves to nothing, so a stale id cannot leave the stage with no source at all.
The button carried its on/off state in a colour fill and nothing else, so a screen reader could not tell whether auto-zoom was on. `aria-pressed` is what the mic and camera buttons beside it already use for the same job.
tsconfig.test.json typechecks this file in CI, and `as any` on the store actions spent that check: the `createProject` stub returned `undefined` where the action promises an `AxcutDocument`, and nothing said so. The import path discards that return today, which is exactly why the stub had drifted unnoticed. `addAsset` and `saveDocument` were already assignable and only needed the cast taken off. The two remaining casts stay: one stands in for the contextBridge surface, the other for a deliberately partial document.
The deadline added in 252ab95 had no test: it lives inside the shell's `loadedmetadata` callback, and that callback is only reachable through Preview, PreviewCanvas, VirtualPreview and a real <video> decoding real media. So the one thing it exists for — a save that never answers not stalling every later event — was resting on reading the code. The chain step moves out of the closure into `runLoadedMetadataWrite`, which is the same shape the handler already had: read the store at call time, guard on the originating project, fold the length in, then hand auto-zoom whatever the store actually holds. The handler keeps only what it was really doing — putting that step on the chain. The stuck-save test does not fail with a wrong value when the deadline is removed; it never finishes, which is the defect. Also covered: the fold-in and what auto-zoom receives, the project-switch guard, the empty cases, and that a document needing no write still lets auto-zoom run. `documentWriteAudit.test.ts` caught the moved write and its row now names the function that performs it.

…efore it The guard at the top of `runLoadedMetadataWrite` speaks for the document as it was before the save; the await after it is exactly when a project switch lands. Past that point the auto-zoom pass was handed whatever the store held — another project's document, or the pre-switch snapshot when the project had been closed. That does not write zooms into the wrong project: `canApplyFreshRecordingAutoZooms` refuses a document that does not hold the pending recording. What it does is worse to diagnose. The passes that run before that check still clear the pending flag, and one of them stamps `appliedFreshRecordingAutoZoomProjectId`, on the document they were given — so a switch during the save silently cancels the auto-zoom for the take that was actually imported, which is the thing this branch exists to deliver. So the ownership check runs again on the settled document, and a document that no longer belongs to the originating project ends the step. Closing the project ends it too: the pre-switch snapshot is not a stand-in for a project that is gone. Both cases fail their tests when the re-check is removed.

Closing this in favour of #622, which is the same change split properly. The problem was mine and it was structural: this PR and #620 both restructured #622 is built on top of #620 instead of beside it. It carries none of #620's changes of its own, and the metadata step keeps #620's design — the shared write queue — with the auto-zoom pass on the same queued task rather than a second serialisation mechanism. Everything raised on this PR is in #622: the primary-asset seed guard and the preview mount it needs (both now #620's), the bounded save, the post-save ownership re-check, |

Summary
1.5 suggested cursor-dwell zooms when a fresh recording opened in the editor. Current main still has the wand, but HUD import only seeded a clip, so a new take landed un-zoomed.
This restores that import pass on the current document model. Zooms stay as editor regions; they are not baked into the MP4.
recordingPrefs.Two things came out of review and are here because this branch introduced them.
The
loadedmetadatachain this branch added awaitssaveDocument, which has nodeadline of its own, so a bridge call that never answers would take every later
callback with it; that save is now bounded by the same helper the auto-zoom write
already used. And the empty-timeline seed now runs only for the asset it is sized
against, with the preview mounting that asset while the timeline is empty — the
guard and the mount together, because either alone is worse than neither.

The editor path is the same on every platform that writes a cursor sidecar. The report and the live take used to check it are Windows / WGC.
Screenshots / video
Two things are visible. The HUD gains one toggle (auto-zoom after recording), separate from the system-cursor control and disabled while the cursor is in system mode. And a fresh take now opens in the editor with zoom regions already on the timeline instead of an empty zoom lane — in the A/B below, four
1.80xregions with the toggle on against none with it off.Testing
Testjob green.npx tsc --noEmitandnpx tsc -p tsconfig.test.json --noEmit.npm run i18n:checkacross the locale set.<video>, on the case the recording flow never reaches: a project holding a5.000 s audio asset first and a 26.516667 s recording as its primary, with an
empty timeline. With the guard alone the mounted source is the audio and no
clip is ever seeded; with both, the mounted source is the recording and the
seed writes one clip at 0–26.516667 s on it. An ordinary single-video project
seeds the same clip either way.
Live A/B on real Windows WGC takes, both arms driven with a real OS mouse
(the HUD is click-through and hit-tests the OS cursor, so a synthesised click
would not have exercised it). Identical choreography each arm: five
move-then-hold points, ~2 s of stillness at each.
focusMode: autoArm A's zero is the toggle, not missing telemetry: replaying Arm A's own sidecar
through
detectZoomDwellCandidatesyields the same four dwells as Arm B, at thesame four focus points (2038–2058 ms each, inside the 450–2600 ms window). Both
arms carried equally zoomable telemetry; only the on arm produced zooms.
Arm B's four zooms are 2000 ms each, centred on their dwells (7.979–9.979,
10.074–12.074, 12.169–14.169, 14.267–16.267 s), and the timeline shows four
1.80x regions where arm A's zoom lane is empty. The toggle state was read off the
HUD tooltip before each take rather than assumed.
Arm A ran in one app process and arm B in a second: after arm A's editor opened,
Ctrl+Shift+Ohid the HUD and did not bring it back, so a relaunch was thedeterministic route to a fresh HUD — which also put arm B on the cold-start
default.
recordingPrefsis in-memory and session-scoped, so a restart cannotcarry a stale toggle across. Everything else was held constant.
Not covered: one machine, one platform, one take per arm; macOS and Linux; the
browser fallback for hosts without the native helper; export (this change writes
editor regions, it does not bake zooms into the MP4).
Scope
Two pre-existing document-write races turned up while reviewing this branch, in
files it touches but did not introduce them to: the
loadedmetadatahandler inNewEditorShellsaves a whole snapshot outside the queue user edits go through,and
runAutoZoomsreads a snapshot, awaits telemetry IPC, then writes. Both havethe same shape on
maintoday. They are not part of restoring the import pass,so they are left alone here and raised separately rather than folded in.
The seed guard above overlaps that separate change, which carries the same fix
for its own copy of the handler. The two are written identically so they merge
cleanly in either order; neither depends on the other landing.
