Switching the zoom level took two clicks: open the select, then pick. The six levels now sit in one row of aria-pressed buttons in the zoom pane, so a level is one click away and all six are visible at once. Labels are the ZOOM_DEPTH_SCALES values the select already showed, and the buttons write through the same updateZoomDepth path, so undo, save and preview are unchanged. Re-pressing the current level is a no-op. Six labels do not fit beside a row label at 300px, so this one control stacks its label above the row instead of using paneRow. Keyboard. The editor shell listens on WINDOW, above React's root container: ArrowLeft/ArrowRight seek the playhead there, and Space is play/pause on a branch that calls preventDefault() -- which cancels a button's own activation. So the row stops its own keys at the group, as the timeline pill does: the arrows with preventDefault, Enter and Space deliberately without, since preventing those is the very thing that breaks activation. Arrows step from the FOCUSED button, not from the selected level. Every level is a Tab stop, so the two can part company, and counting from the selection threw focus across the row -- with 2.2x selected and focus on 5x, ArrowRight moved focus back to 1.8x. For the same reason the no-op guard compares against the level last REQUESTED rather than the depth prop: updateZoomDepth saves the document, so the new prop is a tick behind, and stepping 3 -> 4 -> 3 dropped the way back as a no-op and left the level on 4 with focus on 3. The prop overwrites that request the moment it moves, so a write from undo/redo or the agent is never masked by a stale one of ours. Closes getopenscreen#670.
saveDocument echoes an earlier depth into the store before a later request has landed. Copying that echo into the no-op guard dropped ArrowLeft after 3 -> 4 -> 5, leaving focus on 4 with the level on 5. Pending depths we asked for no longer overwrite the latest request; undo/redo still wins because those depths are not in the set.
Rapid depth steps were two whole-document saves built from the same pre-edit document, so one undo jumped over a level and a later save could drop an unrelated edit. updateZoomDepth now reads the committed document inside the shared timeline queue. Request tracking is a generation per click, not a Set of depths, and resets when the selected zoom region changes. A failed save no longer makes the same level unretryable.
…e queue Superseded generations returned before decrementing inFlight, so a rapid 3-4-5 left the follow-effect blocked and undo could not retarget the no-op guard. Every generation now leaves the pending set when it settles; only the latest may change requestedRef. Rotation, focus-mode, hide-cursor and span writes now read the committed document on the same enqueue chain as depth, so a pending depth save cannot be overwritten by a stale whole-document snapshot from the neighbouring control.
…h queue Queued updateZoomDepth still raced Add Zoom and live/commit focus saves. Gesture writers now enqueue and re-read the committed document; focus and annotation commit snapshot the patch at call time and replay it after in-flight writes.

📝 WalkthroughWalkthroughChangesThe zoom depth dropdown is replaced with six direct buttons. The control supports keyboard stepping, async request ordering, retry after failed saves, and external depth changes. Zoom-field writes now use a serialized patch path.

…setters The level buttons need their saves ordered and built from the committed document, and the neighbouring zoom selects need the same so a pending level is not rebuilt away. That is all getopenscreen#670 requires, so the fix is now one zoom-pane chain in useTimeline: depth, 3D tilt, focus mode and hide cursor share saveZoomPatch, which reads the document inside the chain and resolves saveDocument's answer so a failed level can be retried. Everything else goes back to upstream/main: the shell keeps its own trim queue and paste flow, the other timeline writers and the live/commit paths are untouched, and useSequentialTimelineOps loses its nested-enqueue handling. Serialising every whole-document writer is a separate problem. Store tests keep only what pins this: in-order rapid steps with one undo step each, a tilt change that keeps a pending level, and the false result of a failed save. The E2E zoom fixture moves above the two-clip fixture's comment, which it had split from its function. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Serialize snapshot construction across timeline writes.
enqueueZoomWrite covers only saveZoomPatch. updateTrim, updateZoomSpan, commitZoomFocus, updateAnnotationSpan, and commitAnnotationChange still call saveDocument with whole-document snapshots.
projectStore.saveDocument sends each snapshot to nativeBridgeClient.aiEdition.save and accepts the returned document. The per-project DocumentService.writeQueues serializes disk writes, but it does not reload or merge snapshots. If two paths start from document A, the later queued full-document write can overwrite the first edit with its stale snapshot. The write-epoch check does not detect ordinary concurrent edits.
Route these timeline writes through one shared queue. Queue an operation rather than a prebuilt snapshot, then read the current document inside the queue. Replay each live gesture patch from that fresh document. Alternatively, add optimistic version checks and merging in the shared persistence layer. Add an interleaving regression test that preserves both a zoom-depth edit and concurrent span, focus, or annotation edits.

Summary
Replace the Zoom Level select in the floating zoom inspector with six directly clickable level buttons. All six
ZOOM_DEPTH_SCALESvalues stay visible, the current level is exposed witharia-pressed, and the row is a labelledrole="group".Keyboard behavior stays local to the control: every level remains tabbable, Enter/Space activate the focused button, and arrow keys move one level from the focused button (clamped at both ends) without the editor shell's seek/play shortcuts also handling the keystroke. Re-selecting the requested level is a no-op.
Rapid level changes need ordered persistence. Each click is a whole-document save, and two saves built from the same render's document can land out of order (the main process does not serialise them), so 3 → 4 → 5 could end on 4, and one Ctrl+Z skipped a level. The zoom pane's one-field setters (level, 3D tilt, focus mode, hide cursor) now share one small chain in
useTimelinethat reads the committed document inside the queued task, so a pending level is also not rebuilt away by a neighbouring zoom select. The level write resolves whether the save took effect, so a failed level can be retried. The control tracks each request by generation, so late settlement of a superseded request, a region switch, or an external undo cannot leave it on a stale level.No zoom math, schema, renderer semantics or other timeline writers change.

Before, from #670:
The replacement was driven in the browser shim at the editor's 300px inspector width: six buttons stay on one row with no label clipping; click, Space and arrow-key changes update the selected level; the pressed state and focus ring remain visible.

Only the zoom pane's one-field setters share the new chain. Other whole-document writers (Add Zoom, zoom span drags, the focus live/commit path including Reset focus, trims, clips, annotations, audio, paste) keep their existing behavior, so a pending level save can still race one of them if both are in flight at once, exactly as the previous select could.
