Serialize pending hide and show operations.
Line 73 starts from a non-recording state, which starts hide() in the hook. If that IPC request settles after a successful show(), hide() sets open to false after the show completed. The HUD can then report a closed self-view after recording starts.
Track operation generation or serialize the requests. Add a test that delays hideFloatingSelfView until after showFloatingSelfView succeeds.

Ignore a stale completion when another request is active.
After request 2 reports ready, activeRequestId remains 2 so later camera failure can be correlated. A late ready or failure event for request 1 enters these branches and hides the window. open remains true, so the HUD reports an open self-view while the window is hidden.
Hide only when no request is active. Ignore a mismatched request ID when another request is active. Add coverage for stale ready and failure events after the replacement request becomes ready.

Assert both native reassertions and their order.
The new behavior requires one setVisibleOnAllWorkspaces and setAlwaysOnTop pair before showInactive(), and one pair after it. These assertions check only the call count and whether at least one call matches the expected arguments. They do not catch an incorrect argument or incorrect call order. Assert each invocation and record the call order around showInactive().

Nice feature, and the capture-exclusion plumbing per platform is careful work. A few things below, mostly around the window lifecycle — the self-view can end up holding the camera with nothing on screen, and the recording hand-off has a regression I'd want fixed before merge.
Heads up: I pushed one commit to your branch directly (021b57a) with three small ones, since "allow edits from maintainers" is on. It collapses the duplicate hide() effect, drops the unreachable selfView.unavailable branch in LaunchWindow, and adds the self-view to the activate handler's auxiliary-window exclusion so a dock click still restores a minimized HUD. tsc, tests-tsc, lint, i18n and 66 tests pass on it. Shout if you'd rather I'd left it as comments.
One aside: nothing tests the activate handler, so that third fix is uncovered.
The rest, on lines outside the diff hunks:
electron/main.ts:984 — before-quit fires even when the quit is then cancelled, so this destroys the pre-created window and nothing recreates it in time.
Cmd+Q with unsaved editor changes: before-quit runs and destroys the BrowserWindow, then the editor's close handler at :867-870 preventDefaults, the user picks Cancel, and the app keeps running with this.window = null and destroying = true. The next recording only recreates it lazily inside show() — after startNativeMacRecording has had ScreenCaptureKit enumerate shareable content, which breaks the ordering invariant you assert at :1178-1180.

The hand-off clear moved below the frame/timeline seed, which puts #364 back.
If probeVideoDimensions, probeVideoDuration or saveDocument throws on the first editor mount — locked file, quota, disk error — line 90 throws, so setCurrentRecordingSession(null) on :95 never runs. But createProject and addAsset at :41-42 already committed. Next editor open imports the same recording into a second project, and everything the user saved stays behind in the first one.
The comment on :92-94 still says the clear was moved above the seed precisely to prevent this, so the code and the comment now contradict each other.

The stale-request branch hides the window but never sends visible:false, so the renderer keeps a live camera stream with nothing on screen.
Path: show() while the pre-created window is still loading, the 10s timer fires hideInternal({request-timeout}) (its visible:false is dropped because no renderer listener exists yet), then did-finish-load replays requestCamera with the old id. The renderer calls getUserMedia and reports ready, activeRequestId is null so :167-169 just calls win.hide(), and streamRef in FloatingSelfViewWindow.tsx still holds the MediaStream.
On macOS that means the camera indicator stays lit with no visible self-view until the recording stops — the kind of thing users file as a privacy bug.

The per-request did-finish-load listener is registered with once but never removed when the request is superseded or times out — nothing in finishPending/hideInternal clears it.
Two show() calls during load (or one that times out) each leave a closure capturing its own requestId. When the load finishes, every stale one fires webContents.send("floating-self-view-command", {visible:true, requestId: <stale>}) and the renderer acquires a camera for a request the controller stopped tracking. Same root as the leak above.

precreate() runs unconditionally on every macOS launch, so every user gets a second BrowserWindow and renderer process loading the whole React bundle — App.tsx, i18n, the font loading at :82-87 — permanently resident with backgroundThrottling:false.
Nothing gates it on floatingSelfViewEnabled or on the webcam ever having been turned on, and the only consumer is a HUD button that appears solely during a recording with a live camera track. Worth deferring it to the first time the webcam is enabled, if the SCK ordering constraint allows.

This flips the default editor padding from 50 to 8, which doesn't belong in a floating-self-view PR.
DEFAULT_EDITOR_LAYOUT_SETTINGS.padding also seeds DEFAULT_PREFS.padding (userPreferences.ts:34) and DEFAULT_EDITOR_SETTINGS.padding (editorSettings.ts:120), so every new project and every user without a stored preference gets a visibly different frame. It also means the self-view can't be reverted without reverting the layout change.
Same question for the recordingImport.ts rewrite and the new scripts/macos-ffmpeg-relocation.mjs — could those go in their own PRs?

The ?? "native" fallback writes the legacy token that aspectRatioUtils.ts:19-22 says nothing writes any more — it resolves to the timeline's largest-area asset, described there as "exactly the silent, drifting behaviour the enumeration replaced", and exists only so pre-enumeration projects still open.
So every recording whose probeVideoDimensions misses — an unpatched WebM, or the 5s timeout — becomes a project whose output shape silently changes the moment a larger asset is added. Probably wants an explicit enumerated default instead.

This opens a second getUserMedia on a camera the recorder already holds. useFloatingSelfView reads the existing stream's getSettings().deviceId only to hand it to a fresh, narrower request (width:{max:640}, height:{max:480}).
Chromium then has to satisfy the second format from the same device session, which costs a scale/copy per frame for the whole take, and it adds an independent failure mode — an OverconstrainedError or NotReadableError here surfaces as camera-unavailable even though the recorder's own camera is fine. Could the existing track be cloned instead?

Follow-up on the ScreenCaptureKit side, which I left out of the previous review by mistake. Three things, all about the filter widening.

excludingApplications: excludedApplications, exceptingWindows: [] removes every OpenScreen window from full-display capture, not just the HUD and the self-view.
So recording your display while the editor is open now shows wallpaper where the editor was — which breaks the fairly common case of recording a tutorial about OpenScreen itself. Before this PR SCContentFilter(display:excludingWindows: []) captured it normally.
exceptingWindows: [] is deliberately empty per the doc change, so there's no way to add a window back. Would per-window exclusion (HUD + self-view by window ID) work instead?

Flipping onScreenWindowsOnly to false makes hidden OpenScreen windows resolvable, which is what the exclusion needs — but it also widens the single-window capture lookup at :504, which relied on the narrower enumeration.
Pick a window in the source selector, then minimise it before pressing record: previously content.windows held only on-screen windows, so :504 threw sourceNotFound("No ScreenCaptureKit window found for id …") and the user got a clear error. Now it resolves and SCContentFilter(desktopIndependentWindow:) starts a capture that produces blank or stale frames for the whole take.
Only the display branch needs the broader enumeration — worth scoping the flag to it.

resolveCaptureExclusion returning .none and the recorder's handling of it disagree, and the test sides with the resolver.
CaptureExclusionTests.swift:63 (testLegacyRequestWithoutExclusionsSelectsNoFiltering) decodes {}, asserts .strategy == .none, and its name documents that as degrading to unfiltered capture. But the only consumer, here, turns .none into a hard selfCaptureExclusionFailed — so any full-display request that arrives without excludedApplicationProcessIds refuses to record outright.
Either .none should be unreachable from the resolver, or the test should assert the abort. Right now whichever one you read first is misleading.

Summary
Feasibility gate
Native video PiP was draggable/resizable and remained available across Spaces/fullscreen, but appeared in a full-display saved recording on the target macOS 26.6.2 system. This PR therefore ships the planned BrowserWindow fallback. The window is pre-created hidden so main can inject its native ID into the safe ScreenCaptureKit exclusion request before capture begins.
