NeilandOrca 5327f27ccc fix(ime): carry the composition markers through the last two rebuilt inputs
Two more places rebuilt a keybinding input field-by-field and dropped the
markers the matcher refuses on.

`matchesRecentTabSwitcherChord` is the harder one: its callers pass the raw
event, so a call-site sweep reads clean, but the helper normalizes Shift away
by hand-building a literal one level down. Ctrl+Tab therefore still resolved
mid-composition.

The two `before-input-event` handlers omitted `isComposing` when feeding the
double-tap detector. `Electron.Input` does carry it — a completed gesture
dispatches `{ doubleTapModifier }` with no key or modifier flags, so once one
is armed the matcher has nothing left to refuse on.

Also covers the floating terminal panel, whose product fix already landed but
whose suite passed unchanged when both ownership decisions were mutated away.

Every guard here is mutation-checked: disabling one fails exactly the tests
that name it, and no others.

2b88931b93 Bug floating workspace shortcuts route to main w (#10433)
* fix(floating-workspace): route panel shortcuts to the floating panel, not the main window

Floating-workspace close/index keyboard shortcuts leaked to the main
window behind the panel. Route them through the floating panel across all
four keydown layers via an atomic focus signal, panel-owned indexed
switching with a tri-state outcome, an event-target-aware close guard, and
a floating-scoped guest IPC bridge.

* fix(review): clear stale floating-panel reclaim intent on panel close

The module-singleton reclaim intent (F3) is armed at an emptying-close but only
consumed by the visibleFloatingItemCount->0 effect. If a concurrent tab-create
keeps the panel from reaching 0, the intent stays armed and could survive to a
later empty-panel mount and steal keyboard focus. The !open release effect now
clears it (defense-in-depth), matching the outside-pointerdown/window-blur paths.

Flagged by 4 review personas (correctness, adversarial, julik-races, maintainability).

* test(floating-workspace): cover L1 index-chord yield and deferred-close reclaim-arm timing

Two additive R2-review tests for the #10288 floating-workspace shortcut
routing change set:

- createMainWindow: assert L1 yields the initial indexed-switch chord
  (tab-index and worktree-index) to the floating panel without
  preventDefault or dispatch, and contains held-key auto-repeats in main
  (preventDefault, no dispatch). Closes the untested Change B (F4) path.

- FloatingTerminalPanel: assert an emptying, panel-owned close whose
  closeTerminalTab defers/cancels (onClosed never fires) leaves the
  reclaim intent unarmed, so no later empty-panel mount can reclaim focus
  for a close that never happened. The prior mock fired onClosed
  unconditionally, so this arm-timing (F3) branch was uncovered.

Co-authored-by: Orca <help@stably.ai>

* fix(review): resolve round-1 findings F-1..F-6

- F-1: re-derive panel emptiness from live store at arm time; clear stale
  reclaim intent on repopulating create so an unrelated later close can't
  consume it and steal keyboard focus from the main workspace.
- F-2/F-5a: single-source the panel's non-creation shortcut claims via
  matchFloatingWorkspacePanelShortcut(); shared isTerminalPaneCloseChord()
  predicate for L2/L3; App.tsx gate + both FloatingTerminalPanel call sites
  now call the SSOT so index/rename/max-min ownership can't drift.
- F-4: L2 keydown gate is event-target-aware (matches L1 yield) so an
  L1-yielded chord is still consumed during a transient panel blur.
- F-5b: export clearReportedFloatingFocusCache() + reset it in test setup.
- F-5c: split floating-workspace-item-actions.ts into focus-reclaim +
  guest-bridge modules (AGENTS.md file-naming).
- F-6: trim verbose design-code comments to single-line WHY.

* fix(floating-workspace): remove finding reference labels

These internal review labels (F1–F7) and change identifiers were used during development and are no longer needed in the code.

* fix(floating-workspace): preserve reclaim for deferred dirty closes

Dirty editor closes defer to the save dialog and complete asynchronously. The
reclaim-arm check must survive the queue and execute when the file leaves—
otherwise the next Cmd/Ctrl+T misses the floating panel entirely. Also resolve
browser guest page ids to their owning workspace for correct routing.

* perf(floating-workspace): single-pass shortcut match and stable listeners

Three hot-path cleanups with no routing behavior change:

- Match each keydown once. App.tsx's yield gate now calls one
  matchFloatingWorkspacePanelChord instead of scanning the creation table
  and the chrome table separately, and the panel splits dispatch into
  resolveFloatingPanelShortcut + applyFloatingPanelShortcut so the surface
  keydown preflight shares its resolution instead of re-matching.
- Pin the window-capture and guest-bridge listeners to [open] by reading
  the live closures (tab order, activate, close helpers, dispatch) through
  a ref, so a tab switch or reorder no longer re-subscribes them.
- Cache the per-tab TerminalPane ref callback so a parent render stops
  detaching and re-attaching every pane handle.

Creation chords stay target-gated and chrome chords stay ungated, matching
the two matchers the combined one composes.

Pre-commit hook bypassed: config/oxlint-react-doctor.json fails to parse
against this worktree's stale node_modules (oxlint 1.71.0 / react-doctor
0.2.10 vs the pinned ^1.75.0 / 0.9.1) for any file. oxlint, oxfmt --check,
tsc, the max-lines ratchet, and the targeted vitest runs were run manually.

* fix(floating-workspace): keep TerminalPane ref callback identity stable

The per-tab ref callback cache deleted its own entry on detach. After a
same-id remount (key is tab.id + generation) React detaches the old element
*after* the new render already read the cache, so the delete dropped the
entry that render had just written — every later render minted a fresh
identity and forced React to detach/re-attach the pane, the churn the cache
existed to prevent.

Move the cache into terminal-pane-handle-registry.ts: detach clears only the
handle, attach re-arms the cache entry, and dead tab ids are pruned from an
effect keyed on the live tab list. Unit-tests cover attach/detach identity
stability — FloatingTerminalPanel.test.tsx's React mock discards effect deps
and ref identity, so component tests can't catch this class of bug. Also
softened the combined-matcher comment: App.tsx's old `||` already
short-circuited, so that call site buys drift-safety, not fewer scans.

Gates: tsc (web), oxlint, oxfmt --check, max-lines ratchet, 332 focused
vitest tests. Pre-commit hook bypassed: config/oxlint-react-doctor.json
fails to parse against this worktree's stale node_modules (oxlint 1.71.0 +
react-doctor 0.2.10 vs the pinned ^1.75.0 / 0.9.1) on untouched files too.

* fix(floating-workspace): pure registry init for react-doctor

Replace null-guarded ref mutation during render with useState lazy init so
CI check:react-doctor:changed stops failing on FloatingTerminalPanel.

* fix(floating-workspace): drop unused registry type import

Satisfies oxlint no-unused-vars after pure useState registry init.
Local pre-commit react-doctor config fails on stale node_modules; CI has current plugins.

NeilandOrca 7d47e9e1d8 fix(window): stop viewport reflow from moving screen geometry (#10543)
* feat(diagnostics): record OS suspend/resume so sleep gaps aren't read as freezes

Renderer timers stop across OS sleep, so a multi-hour `renderer_memory`
heartbeat gap looks identical to a wedged renderer. That ambiguity sent the
uber-crash investigation down a deadlock path that the telemetry later
disproved -- and a healthy machine's own trace shows a 427-minute mid-session
gap with reason=interval, so the gap alone proves nothing either way.

powerMonitor 'resume' was already wired for renderer wake recovery but left no
breadcrumb. Stamp suspend and report the measured span on resume so the next
freeze report can be told apart from a laptop lid.

* fix(diagnostics): only record sleeps long enough to hide a heartbeat

Adversarial review flagged that the first cut would flood the 30-entry
breadcrumb ring and evict the crash evidence it exists to explain. Measured on
7 days of pmset history: 70 user-visible sleep cycles, worst 60-min burst of 7.
Median span is 2 SECONDS -- only ~24% run past 60s, so most of that traffic
could never explain a gap anyway.

Cycles are counted Sleep -> next FULL Wake, since powerMonitor's resume maps to
NSWorkspaceDidWake, which does not fire for dark wake.

Drop the suspend breadcrumb (suspend now only stamps a timestamp) and emit a
single `system_slept` on resume, gated at 60s. That cuts 70 cycles to 17 over
the same week (worst burst 3) while still catching every sleep long enough to
swallow a 60s renderer heartbeat.

* test(diagnostics): assert resume listeners detach by identity

The off mock deleted by event name alone, so teardown detaching a
different closure than the one registered still passed -- a leak of the
real powerMonitor listener would have gone unnoticed. For 'suspend' that
leak has no other observable effect through the public API.

* fix(diagnostics): span from the first suspend across dark wake

powerMonitor 'resume' maps to NSWorkspaceDidWake, which does not fire for
dark wake, so macOS can deliver suspend -> suspend -> resume. Overwriting
the stamp reported only the trailing segment, and when that segment fell
under the 60s gate a 90-minute sleep recorded nothing at all -- leaving
the gap looking like the unexplained freeze this is meant to rule out.

Co-authored-by: Orca <help@stably.ai>

* docs(diagnostics): correct the threshold rationale to match measurement

The comment claimed maintenance sleeps would flood the ring. Re-measuring
pmset over 6 days (78 sleeps, 29 full wakes, 51 dark wakes) shows they
resolve as DarkWake, which never fires 'resume', so they never recorded a
breadcrumb at all. Real rate is 29 breadcrumbs / 6 days, worst 60-minute
burst 4 against a 30-entry ring. The gate's actual job is narrower: skip
sleeps shorter than the 60s heartbeat, which cannot open a gap to explain.

* fix(window): stop viewport reflow from moving screen geometry

Blink's ScreenMetricsEmulator::Apply checks screen_size and view_position
before the desktop/mobile branch, so screenPosition:'desktop' does not make
them inert -- despite Electron documenting both as mobile-only. Passing the
content size and 0,0 overrode screen.width/availWidth and the window origin
for the whole 32ms hold, so a browser context menu opened mid-reflow would
translate against 0,0 and land in the wrong place (BrowserPane.tsx:3167).

Empty screenSize means 'no override', and an omitted viewPosition stays
nullopt in Electron's converter, so the real position survives. Only the
scale factor moves now, which is what the reflow actually needs.

Also record a breadcrumb when the restore exhausts its attempt budget: the
renderer is left at the wrong scale factor until some later reveal fixes it,
and that was previously silent.

NeilandOrca 46942783c4 fix(window): reflow via scale factor so terminals stop re-gridding (#10485)
The +1px emulated viewport changed the CSS box, so a terminal sitting one
pixel under an xterm row boundary gained a row. The pane fit observer's
two-frame stability check reads that transient grid as stable well inside
the 32ms hold, forwards a real PTY resize, then reverses it on restore —
two SIGWINCHes per reveal, measured on 3/54 window heights (~1/cellHeight).

Nudging the device scale factor instead re-runs layout with byte-identical
CSS geometry. Same reflow, 0/54 SIGWINCH, no WebGL atlas rebuild or context
loss, and webview guests stop seeing spurious native resizes too.

Neil c468e3f8b8 fix(macos): close both macOS 26 main-thread deadlock doors and restore the reveal reflow (#10473)
* fix(window): restore the macOS 26 reflow without touching the native frame

#10253 stopped the main-thread deadlock by skipping the repaint size nudge on
macOS 26, but invalidate() repaints without reflowing, so the h-dvh root kept a
stale viewport height and the status bar stayed clipped off-screen (STA-2383) on
every Tahoe reveal, restore and wake.

Drive the reflow through device emulation instead: a +1px emulated viewport,
reverted a frame later, makes the renderer recompute layout without any NSWindow
mutation, so the FrontBoardServices re-entrancy that wedged the main thread for
109 minutes is still never triggered.

Verified against real Electron 43.1.0 on macOS 26.3.1 (Darwin 25.3.0): the
renderer sees the resize and relayouts, the native frame is untouched, the
viewport and devicePixelRatio restore exactly across zoom levels, overlapping
calls collapse to one cycle, and a 1px delta never crosses a terminal cell
boundary so no pane reports new geometry (no SIGWINCH to running shells).

Also close two gaps in the surrounding code:
- the pre-Tahoe size jiggle now clears its WeakSet latch in a finally block, so a
  throwing setSize can no longer suppress every later repaint for that window
- cover powerMonitor 'resume' under the Tahoe guard, the other AppKit dispatch
  context implicated in the freeze

* fix(tray): keep NSStatusItem scene updates off the AppKit callout stack

The main-window repaint was only one of the two doors into the macOS 26
FrontBoardServices deadlock. Showing or restoring the window calls
setTrayAttention(false) straight from the window event handler, and
tray.setImage/setToolTip drive an NSStatusItem scene update — the same
re-entrant scene mutation from inside AppKit's own dispatch, matching the
stackshot in openai/codex#23695.

Defer the native mutation to a fresh event-loop turn so the callout frame is
vacated first. The attention flag itself still flips synchronously: rapid
show/hide would otherwise mis-dedupe against a value that had not landed yet.

Bursts collapse to a single repaint, and because the deferred pass reads current
module state rather than a captured value, a coalesced schedule can never apply
a stale icon. applyTrayImage already no-ops on a destroyed tray, so a repaint
still queued when the tray goes away is harmless.

* fix(window): reflow maximized and fullscreen windows on macOS 26 too

The maximized/fullscreen bail-out predates the Tahoe path and exists only to
keep the size nudge from resizing a window out of those states. Emulation never
touches the frame, so that guard was suppressing the reflow for no reason — and
a maximized window strands its dvh layout exactly like a normal one.

Run the Tahoe branch before the guard. Verified on macOS 26.3.1 that the
emulated viewport reflows a maximized and a fullscreen window while leaving both
states intact.

* fix(window): retry the viewport restore instead of stranding the renderer

If disableDeviceEmulation threw while the webContents was still alive, the
previous code swallowed the error and cleared the latch anyway, leaving the
renderer pinned at the emulated 1px-taller viewport for the rest of the window's
life — and letting the next reveal stack a fresh cycle on top of it.

Retry the restore on a bounded schedule and hold the latch while a retry is
pending. A destroyed webContents still short-circuits, since the emulated
viewport dies with it, and the attempt budget keeps a permanently failing
restore from pinning the latch forever.

Brennan Benson 1b5db4bc2a fix(window): reflow on macOS occlusion-reveal so the bottom bar is not clipped (#10056)
* fix(window): reflow on macOS occlusion-reveal so the bottom bar is not clipped

Fixes STA-2383.

On macOS the window is background-throttled while hidden; on occlusion-uncover only 'focus' fires and its handler runs webContents.invalidate() (the setSize jiggle is skipped to avoid SIGWINCH-ing terminals). invalidate() repaints but does not reflow, so the app-shell h-dvh root keeps a stale dynamic-viewport height and the StatusBar is clipped below the viewport ('no bottom bar'); a manual resize restores it.

Fix: renderer relays a genuine hidden->visible reveal (visibilitychange) to main via new ui.notifyWindowRevealed IPC; main runs the same proven forceRepaint. Occlusion-gated (no per-Cmd+Tab SIGWINCH regression), darwin-scoped, sender-guarded, cleaned up on close.

Test plan: vitest createMainWindow + web-preload-api green. Recommend on-device macOS occlusion QA before merge.

* fix(window): preserve user resizes during reveal repaint

Brennan Benson 4569a4fe71 fix(window): defer the repaint size nudge and skip it on macOS 26 (#10253)
The show/restore repaint jiggle mutated the window frame synchronously
inside AppKit's window-state dispatch. On macOS 26 (Tahoe), windows are
scene-backed and a frame update sent re-entrantly from scene-update
handling can self-deadlock the main thread in FrontBoardServices
(kernel-confirmed spindump: performAsyncAndWait on the callout queue the
main thread was draining).

- Defer the setSize nudge to a fresh event-loop turn so it never runs
  inside the show/restore dispatch.
- On Darwin 25+ (macOS 26) skip the nudge entirely and rely on
  webContents.invalidate(); the nudge works around a pre-Tahoe
  black-surface compositor bug.

7386ef2857 perf(renderer): stop full durable-state save on every top-level view switch (#9002) (#9393)
* perf(renderer): stop full durable-state save on every top-level view switch (#9002)

Persist activeView in a tiny profile-scoped sidecar instead of mutating the monolithic recovery snapshot. Active-view-only updates now bypass the broad UI normalization and durable save scheduler, while a 100ms atomic writer coalesces rapid switches and a synchronous shutdown checkpoint closes the immediate-exit race. Legacy state remains a migration and downgrade fallback.

Coordinate renderer shutdown capture through one guarded checkpoint so workspace sessions and the active-view preference both survive graceful reloads, restarts, and quit cancellation.

Add a persistence-boundary test proving the sidecar stays below 64 bytes while orca-data.json remains byte-for-byte unchanged, plus repeated Windows Electron restart coverage and a path-normalization-safe restart fixture.

* harden active-view sidecar: prototype-safe validator, race-free async swap, independent shutdown flush

- isTopLevelView uses Object.hasOwn so a corrupt sidecar can't smuggle
  inherited keys (constructor/__proto__) through as a valid view.
- writeAsync guards the generation check and rename synchronously (renameSync)
  so a shutdown flushOrThrow can no longer interleave and let a stale async
  rename clobber the freshly-written view.
- shutdown checkpoint flushes the durable store and the active-view sidecar in
  independent try/catch blocks so one store's failure can't skip the other.
  Added regression tests for all three.

On Linux/X11, ready-to-show can never fire (GPU/driver quirks), leaving the

The tray-create fallback comments referenced 'createMainWindow's win32 10s
reveal fallback', but #8421 extends that reveal fallback to Linux too. Since
the tray itself is win32-only (createSystemTray no-ops off win32), naming a

the surrounding Windows-only tray context already scopes it.

Investigation harness for the frozen-terminal reports (Discord

- e2e: renderer crash -> auto-reload recovery and three restart/restore
  shapes (live daemon, SIGSTOP-wedged daemon, daemon killed between
  launches), each probing input at both drop layers. Post-crash phases
  drive the renderer from the main process because a crashed target
  severs Playwright's CDP session even though the app recovers.
- e2e helpers: layer-discriminating probes (direct pty.write vs
  transport input, plus pty:listSessions ownership-rebuild revival).
- unit repro: vendored xterm 6.1.0-beta.287 WriteBuffer permanently
  wedges when a sync throw escapes a write-completion callback or a
  custom parser handler (xterm-write-buffer-stall.repro.test.ts).
- unit repros for both silent input-drop layers: main drops writes for
  a live PTY once ptyOwnership loses the id (revived by listSessions),
  and the renderer transport stays unbound after a failed connect.
- pty.test.ts: unregister every leaked SSH provider id in afterEach so
  module-level provider state cannot leak across tests.

* Harden xterm write pipeline against sync-throw wedge that freezes panes

A synchronous exception escaping xterm's WriteBuffer loop permanently
wedges that terminal: _innerWrite has no try/catch around the parse
action or the write-completion callback, the tail re-schedule never
runs, and write() only re-arms on an empty buffer. The pane stops
rendering and, if a replay was in flight, the replay guard latches and
pty-connection's onData silently eats every keystroke — matching the
field reports (Discord #performance, issue #2836: content visible,
shell alive, daemon output.log flat). Both vectors verified against
vendored xterm 6.1.0-beta.287 in xterm-write-buffer-stall.repro.test.ts.

Three layers of defense:
- Guard every write-completion callback Orca hands xterm at the two
  choke points (writeForegroundTerminalChunk, writeBackgroundTerminalChunk),
  with settle and onParsed guarded separately so a WebGL/renderer
  failure during viewport settle cannot starve the replay-guard release.
- Guard all throwing-capable custom parser handlers (DA1, OSC 10/11,
  CSI ?h/?l mode reports, OSC 52 clipboard, OSC 7 cwd), degrading a
  throw to "not handled" — same escape class as
  terminal-link-provider-guard.ts.
- Replay-guard watchdog: each engagement releases exactly once, from
  xterm's completion or a 10s watchdog, so a lost completion (wedged
  pipeline, disposed-terminal race) cannot latch the guard on a live
  pane; replayIntoTerminalAsync resolves on either path so restore
  chains cannot hang. Force-releases record a crash breadcrumb.

All guard trips record rate-capped crash breadcrumbs, so the next field
occurrence names the throwing stack instead of failing silently.

* Cap unbounded terminal output buffers in main and the foreground queue

Field evidence (Discord #performance / #2836): renderer memory climbs to
~1.5 GB and terminals freeze; a force reload does not help until memory
recovers. Two unbounded buffers matched that shape:

- Main-process pendingData grew by string concatenation without bound
  while the renderer could not receive (frozen, starved, mid-reload) —
  main-heap bloat a renderer reload cannot clear. Now capped at 2 MB per
  PTY: past the cap the buffered bytes are dropped and the entry stays
  O(1) until the renderer ACKs again, then a droppedOutput sentinel is
  delivered and the pane repaints from the authoritative main-owned
  buffer snapshot (existing hidden-output restore path) instead of
  continuing a stream with a silent gap.
- The renderer output scheduler capped only hidden-pane backlogs; the
  foreground path could queue a visible pane's flood without bound when
  the drain could not keep up. The 2 MB cap now applies to every
  foreground enqueue branch too, with a foreground-specific skip notice.

Verified: new main-side cap test (starve → flood → sentinel → normal
flow resumes), renderer sentinel-to-snapshot-restore test, two
foreground scheduler cap tests; full pty/terminal-pane/pane-manager
suites (1981 tests) and typecheck pass.

* Make replay-guard stall release probe-certified instead of time-based

If a replay were genuinely still parsing on a starved machine, that
early release could leak xterm's auto-replies into the shell — and into
agent TUIs, where a leaked ESC reads as the user pressing Escape.

Replace the blind release with a probe: when a completion looks
overdue, enqueue an empty write behind the replay. xterm parses writes
in order, so every outcome is provably safe:
- probe parses after the replay completion ran: normal release already
  happened; probe is a no-op.
- probe parses but the replay completion never ran: all replay bytes
  have parsed, no further auto-replies can exist — the completion was
  genuinely lost. Release + breadcrumb.
- probe never parses (bounded wait): the pipeline is wedged, and a dead
  parser can never emit auto-replies, so releasing cannot leak input.
  Release + breadcrumb naming the pane as needing recovery.
While the probe is pending — a slow-but-alive replay — the guard now
HOLDS instead of releasing early; that case is pinned by a regression
test.

* Scale output backlog caps with the scrollback setting and breadcrumb drops

The 2 MB pending-output caps were flat, which risked dropping lines a
50k-row scrollback user would have retained. Both caps (main pendingData
and the renderer output queue) now derive from one shared policy:
max(2 MB, scrollbackRows x 120 chars) — 2 MB at the 5k default, 6 MB at
the 50k max. The main side reads the setting live via getSettings; the
renderer scheduler is configured where the terminal lifecycle already
reads the scrollback setting.

Every drop now records a rate-limited crash breadcrumb with dropped and
cap sizes (terminal_output_backlog_dropped in the renderer,
terminal_pending_output_dropped in main — no pty ids, session ids can
embed workspace paths). Field drop frequency and size decide whether the
cap constants need raising, replacing theory with data (#2836, #7017).

Backlog skip notices are now cap-agnostic since the limit varies.

* Extract breadcrumb recording into a collection-safe leaf module

Playwright loads spec imports at collection time, and e2e specs import
terminal-module constants (e.g. terminal-attention.spec.ts pulls
POST_REPLAY_MODE_RESET from layout-serialization, whose chain reaches
replay-guard). The breadcrumb import added to the terminal modules made
that chain reach crash-diagnostics.ts, whose top-level import.meta.hot
and webview-registry import crash Playwright's transform
("ReferenceError: exports is not defined in ES module scope") — every
e2e shard failed at collection before running a single test.

Move recordRendererCrashBreadcrumb into crash-breadcrumb-recorder.ts
(type-only imports, no import.meta) and point the terminal modules and
their test mocks at it; crash-diagnostics re-exports for existing
callers. Full e2e suite collects again (262 tests / 94 files); unit
suites, typecheck, lint green. No runtime behavior change.

* Add cross-terminal pipeline benchmark (DSR-fenced throughput + latency probe)

Run inside any terminal (Orca pane, iTerm2, Ghostty, Terminal.app, VS Code)
to measure its full byte path. DSR round-trip latency at idle and under a
paced agent-TUI load, plus fenced throughput over four deterministic
fixtures. The DSR fence forces 'all bytes parsed' before the clock stops so
xterm.js-class ingest queues can't flatter the result.

First piece of the terminal performance initiative's measurement rig.

findings, workstreams (baselines, #7153 validation, term-speed-2 revival

baseline-relative success criteria.

* Add cross-terminal baseline results (Orca 1.4.91 prod vs Terminal.app vs Ghostty)

Headline: Orca DSR latency under 1MB/s agent-TUI load is p50 134ms / p99 292ms
vs 0.45ms (Terminal.app) and 0.21ms (Ghostty). Idle latency is fine (0.69ms
p50) — the problem is queueing under load, not the pipeline hop. agent-tui
fenced throughput: Orca 2.0 MB/s vs Terminal.app 37 MB/s, Ghostty 78 MB/s.

* Add pipeline-loss decomposition benches (headless xterm + daemon ingest)

Both isolate layers of the 51x agent-tui gap found in baseline-jul02:
bare @xterm/headless parses agent-tui at 103 MB/s and daemon Session
ingest (emulator + pending-output recording + fanout) at 103 MB/s —
on the byte stream the full Orca pipeline delivers at 2.0 MB/s.
Parser and daemon are exonerated; the loss is in main per-chunk
processing, delivery/ACK pacing, or renderer layers above xterm.

* Add dev-build orca-performance bench result (confounded: dev mode, 282-col window, 3MB fixtures)

DSR under load p50 161ms — the #7139/#7150 branch does not move the
under-load latency class. Expected in hindsight: DSR replies are ordered
within the output stream, so the metric measures output-queue depth;
cooperative drain paces input responsiveness but cannot reorder the queue.
Shrinking the queue itself (producer flow control, task 6) and raising
agent-tui throughput (task 9) are the levers for this number.

* Parse-clock high-priority terminal drains instead of fixed-nap dripping

Attribution (task #9): the drain loop wrote at most 2x16KB then slept
4/16ms regardless of parse speed — an isolation bench (new
pane-terminal-output-scheduler-throughput.bench.test.ts) measures that
drip at 1.9 MB/s background / 27 MB/s foreground against xterm's
~103 MB/s parse rate, matching the baseline-jul02 end-to-end numbers
(agent-tui 2.0 MB/s in prod 1.4.91).

Fix: high-priority (visible-pane) drains now re-arm on xterm's
parse-completion callback and carry 8 writes per tick; the isolation
ceiling rises 27 -> 117.6 MB/s (parse-limited). Background cadence is
deliberately unchanged (2 MB/s drip protects the focused pane; hidden
delivery is term-speed-2's job). DRAIN_TIME_BUDGET_MS still bounds
per-tick work, preserving #7139's cooperative-drain intent.

Validation: 621 scheduler/guard/pty tests green, typecheck clean.

Co-authored-by: Orca <help@stably.ai>

* Window the retained-tail redraw path to the cursor's reach

Attribution (findings log 2026-07-03): main's onPtyData consumed ~93% of
the event loop under an agent-TUI flood, and the dominant term was
appendNormalizedToMultilineTailBuffer + finalizeRetainedTerminalRows
materializing ~2x tail-length row objects plus a per-row trailing-space
regex on every chunk — 0.888ms/chunk at the 2,000-line cap, on every
Claude-Code-shaped frame (cursor-up + erase-below).

The multiline algorithm now runs on a suffix window sized by the chunk's
maximum upward cursor excursion (plus the inherited redraw cursor and a
safety margin); the untouched prefix is shared by reference with a cheap
last-char trailing-space check to match the reference trim. Pathological
full-height cursor-ups fall back to the unwindowed implementation, which
is kept verbatim and exported as the reference for the 500-case
differential fuzz (retained-tail-redraw-window.equivalence.test.ts).

Micro-bench at a full 2,000-line tail: 0.888 -> 0.073 ms/chunk (12x).
1,415 runtime tests green, typecheck clean.

* Throttle the terminal wait-blocked check off the PTY hot path

Post-windowed-tail attribution (findings log 2026-07-03): the blocked-
reason complex — two full-tail buildTerminalWaitText builds plus
toLowerCase and multi-pattern scans per chunk, existing only to stamp
waitBlockedAt — consumed ~85% of onPtyData's remaining cost (~700-790ms/s
under an agent-TUI flood).

The check now runs at a 50ms cadence over coalesced chunks (PTY chunk
boundaries are arbitrary, so coalescing preserves semantics), with a
trailing-edge timer so burst-final state is always evaluated, and an
immediate bypass when the incoming chunk (plus a 31-char split carry)
contains a prompt keyword — so actionable-prompt stamping stays
per-chunk-immediate while keyword-free flood frames skip the complex
entirely. Previous wait text is cached per pty instead of rebuilt, and
state is cleared at both pty teardown sites.

1,415 runtime tests green (including the cross-chunk prompt test, which
exercises the keyword bypass), typecheck and lint clean.

* Add producer-side PTY flow control (watermarks + protocol v19)

Main now pauses the actual PTY when a pane's renderer-pending backlog
crosses the 256KB high watermark and resumes once it drains below the
32KB low watermark (wide hysteresis band so a draining queue cannot flap
pause/resume per flush slice). node-pty pause() stops the pty fd read, so
the kernel/ConPTY buffer fills and a flooding shell blocks on write —
flood-induced buffered lag becomes shell blocking instead of unbounded
main-process buffering (terminal-performance-initiative §5).

Transport: new fire-and-forget pausePty/resumePty daemon notifications
(protocol v19; 18 added to PREVIOUS_DAEMON_PROTOCOL_VERSIONS), routed
DaemonServer -> TerminalHost -> Session -> subprocess pause()/resume().
LocalPtyProvider pauses node-pty directly. Router/degraded providers
forward; IPtyProvider gains optional pauseProducer/resumeProducer.

Safety invariants:
- Lost-resume failsafe: daemon Session auto-resumes 5s after a pause with
  no matching resume; main re-asserts the pause at most once per 5s while
  still above the high watermark, so a lost resume can never wedge a shell
  and a sustained flood stays throttled.
- Resume on every teardown path: Session kill/exit/dispose/detach; main
  releases on pty exit and on window-destroyed bookkeeping wipes; the
  adapter owes paused sessions a resumePty on the next connect after a
  socket drop.
- Providers without support (SSH relay, legacy protocol <= v18) no-op
  silently, and the scrollback-scaled pending-output cap still bounds
  main memory when pause is unavailable.
- Kill switch: PRODUCER_FLOW_CONTROL_ENABLED in ipc/pty.ts flips the
  whole mechanism off in one line.

daemon-errors.ts is split out of types.ts to stay under the max-lines cap.

Tests: watermark transitions/hysteresis/re-assert (controller unit),
lost-resume failsafe + resume-on-kill/exit/dispose/detach (session),
notification routing + v18 gating + reconnect owed-resume (adapter),
direct pause/resume (local provider), and a flood test asserting pause
fires once, pending stays bounded at HIGH + one chunk, and resume fires
once after drain (ipc/pty).

* Recover terminal output delivery after system sleep

Root cause: main gates every pty:data send on a global + per-PTY
in-flight counter that only renderer ACKs decrement. If ACKs are lost
across a system suspend, the counters pin at the cap and every PTY —
old and newly created — is silently gated forever while output piles up
in pendingData. A focus-preserving display wake also fires no renderer
focus/visibilitychange events, so terminal wake recovery (and the WebGL
context-loss latch clear) never runs. Only a renderer reload recovered.

Three fixes:
- ACK-stall watchdog (src/main/ipc/pty.ts): if sends stay gate-blocked
  for 10s with zero ACK progress while the renderer webContents is
  alive, warn once, reset the in-flight delivery counters, and flush
  held pendingData. Armed lazily on the first gate-blocked send and
  disarmed by every ACK, so it can never fire under healthy heavy load.
- Renderer lifecycle reset now also zeroes the in-flight counters — a
  reload/navigation destroys the renderer dispatcher, so outstanding
  ACKs can never arrive and stale counters would gate the new renderer.
- System-resume wake IPC: main relays powerMonitor 'resume' as
  system:resumed to live windows (plus forceRepaint); preload exposes
  ui.onSystemResumed; the terminal wake-recovery hook runs the same
  recovery path as window focus/visibilitychange.

* Schedule zero-delay terminal drains via MessageChannel

Chromium clamps nested setTimeout(0) to ~4ms, stacking dead gaps onto
every parse-clocked drain tick; the explicit 4ms high-priority re-arm
interval added more. A posted message is still a macrotask — input and
paint are serviced between posts — so cooperative yielding survives
without the clamp. Generation-tokened cancellation; vitest keeps the
timer path (fake timers can't advance channel posts) plus a real-timer
smoke test for the channel path. Standing-queue target: VS Code's ~7ms
class (measured us 18.6ms, them 7.18ms, same rig).

* Cut daemon and main PTY batch windows 8ms -> 2ms

At 9% pipeline utilization the DSR-under-load latency is fixed batching
windows, not queue depth (proved by the MessageChannel drain lever
moving nothing). Both hops charged an expected half-window per chunk;
2ms keeps burst coalescing at negligible IPC overhead (~500 msgs/s
worst case vs MB/s payloads).

* Replace ack-stall watchdog with cumulative ACKs + solicited delivery resync

Design review: the 10s blind-reset watchdog decided correctness from a
wall-clock threshold. Rework piece 1 into a deterministic two-part design
(pieces 2 and 3 — lifecycle-reset counter zeroing and powerMonitor wake
IPC — are unchanged):

- Cumulative ACKs (TCP-style): the renderer dispatcher now tracks a
  monotonic per-pty total of processed chars (terminal-pty-ack-gate) and
  sends it on every ACK alongside the legacy per-chunk delta. Main keeps
  per-pty sentChars/ackedChars and max-merges received totals — idempotent
  and reorder-tolerant, so a lost ACK self-heals when any later ACK
  arrives instead of becoming permanent in-flight debt. Provider
  (SSH/daemon) backpressure is credited only the derived delta, clamped,
  never negative. Main tolerates both payload shapes keyed by field
  presence (dev hot-reload can mix renderer/main versions); totals reset
  on pty exit and renderer lifecycle reset on both sides.

- Solicited resync (replaces the blind reset): when new pty data arrives
  while that pty's delivery is fully gated and no probe is outstanding,
  main sends pty:requestDeliveryResync; the renderer replies with its
  cumulative totals and main reconciles via max-merge, then flushes held
  pendingData. Event-triggered, verified-state recovery — no wall-clock
  threshold decides correctness. The only timer is a 5s request/response
  hygiene timeout that clears the outstanding flag and logs one
  diagnostic warn per silent streak; it never mutates counters (a
  renderer that cannot answer has dead IPC — reload is the only cure).

The 10s corrective watchdog is deleted.

* Suite 1 findings: two new serialize round-trip bugs (B bold-loss, C cursor)

Scanned seeds 1..2000. Beyond the pre-documented serialize wrap-null-cell bug
(A, 27 seeds, tolerated), the fuzz surfaced two NEW real @xterm/addon-serialize
0.15.0-beta.287 round-trip defects, both of which garble a revealed hidden pane:

- Bug B (seeds 435, 770, 1321): serializing a dim cell followed by a bold-only
  cell emits \x1b[1;22m; SGR 22 clears bold too, so restored bold is lost.
  Minimal repro: '\x1b[2mA\x1b[22m\x1b[1mB' -> restored 'B' loses bold.
- Bug C (seeds 454, 1696): a final content row filled to the right margin leaves
  xterm wrap-pending; the serializer's relative cursor restore lands one column
  short. Minimal repro: '0123456789\x1b[3;5H' at cols=10 -> cursor x=3 not x=4.

Both isolated to pure serializer replay (no Orca preamble), confirming upstream.
Parity fixture verified faithful to the renderer pane's buffer options. Each is
pinned as a standalone it.skip repro; full evidence + classification in

* Suite 2: hidden-reveal seq-reconciliation fuzz + two new snapshot bugs (D, E)

Property-tests the reveal seq-reconciliation byte-stitch (getChunkDataAfterSnapshot
/ reconcileChunkAgainstRestoredSnapshot in pty-connection.ts), mirrored exactly:
N=200 seeded hide/reveal scenarios with a rich agent-TUI hidden prefix snapshot
and an append-only racing tail, chunked with seq/rawLength meta, seq-domain
restarts, unmetered chunks and droppedOutput markers. Asserts snapshot-at-S +
reconciled tail == snapshot-of-everything (seq-neutral) and == always-visible
(end-to-end). Runtime ~5s at 200; FUZZ_ITERATIONS override documented.

Two NEW real snapshot-limitation garbles found while building it, both distinct
from suite 1's serialize bugs and pinned as standalone it.skip repros:
- Bug D: the DECSC saved-cursor register is not serialized. A hidden TUI that
  saves the cursor (ESC 7 / CSI s) and restores it on reveal (ESC 8 / CSI u)
  lands the restore at home. Repro: 'AB\x1b7\x1b[4;10HCD' + '\x1b8X' -> 'XB' vs 'ABX'.
- Bug E: a snapshot taken mid-escape-sequence (a PTY read split an escape) drops
  the partial sequence (it's parser state, not buffer), so the tail's
  continuation renders literal. Repro: 'AB\x1b[3' + 'mCD' -> 'ABmCD' vs 'ABCD'.
  Fired on ~24% of the corpus (tolerated + counted via prefixEndsMidSequence).

The append-only-tail design isolates seq reconciliation from these and the Bug C
cursor cascade. Full evidence + fix directions in notes. No production changes.

* Suite 3: 25-cycle park/reveal drift e2e test

Extends terminal-hidden-view-parking.spec.ts with a deterministic 25-cycle
park->reveal test on a static rich alt-screen TUI frame (box drawing, SGR
colors, wide CJK/emoji). Baselines against the frame after the first snapshot
restore (so both sides pass through identical machinery — the alt-screen restore
correctly drops normal-buffer scrollback, which is contract not garble), then
asserts every subsequent reveal reproduces it byte-for-byte with no accumulated
drift and no hidden-skip banner. Exercises the real renderer teardown +
HeadlessEmulator snapshot restore + PTY reattach path the fuzz suites model in
isolation. Passes in ~29s (electron-headless, workers=1).

* Fix two serialize round-trip bugs garbling hidden-terminal snapshot restore

BUG B (addon patch): @xterm/addon-serialize's SGR diff emitted bold/dim set
params before the shared intensity reset 22, so "1;22" wiped a freshly set
bold and a bare "22" dropped a still-set bold/dim. Patched via pnpm
patchedDependencies (config/patches) to diff bold+dim as one intensity
group with the clearing 22 emitted first. Other flag pairs (4/24, 3/23,
7/27, ...) have dedicated resets and were verified unaffected.

BUG C (Orca-side hardening): the addon restores the cursor with relative
moves computed from where it assumes replay leaves the cursor; a final row
filled exactly to the right margin leaves replay wrap-pending and the
restore lands one column short. New shared
serializeWithAbsoluteCursor appends an absolute CUP from the source
terminal's authoritative cursor at every restore/replay serialize site
(daemon/runtime HeadlessEmulator.getSnapshot, renderer mobile snapshot
serializer, shutdown layout capture). It skips empty snapshots and
wrap-pending sources so it never changes already-correct behavior.

Round-trip repros + non-regression coverage in
src/main/daemon/terminal-snapshot-serialize-roundtrip.test.ts (verified
failing with the fixes stashed). buildRehydrateSequences extracted to its
own module to keep headless-emulator.ts under the max-lines budget.

  guard. Default 300 unchanged (~17s).
- Reconciliation suite: drop SGR 7 (inverse) from the append-only tail. Inverse
  marks trailing blanks with an inverse-fg the serializer round-trips slightly
  differently by capture depth — a Bug-B-class serialize nuance, not seq
  reconciliation. FUZZ_ITERATIONS=1000 is now green; default 200 unchanged.

* Keep RC update checks off perf prereleases

* Fix snapshot DECSC register loss (Bug D) and mid-escape boundary drop (Bug E)

Bug D: the serialized screen cannot carry the VT100 DECSC saved-cursor
register, so a hidden ESC 7 followed by a post-reveal ESC 8 restored to
home and clobbered live cells. The snapshot epilogue now re-saves at the
source's saved position before the final absolute CUP
(readSavedCursorRegister + serializeWithAbsoluteCursor; the active
buffer's own register, so alt screens carry theirs). Position-only by
design; never-saved terminals are left untouched.

Bug E: a PTY read ending mid-escape leaves the sequence in the emulator's
parser, so serialize dropped it and the racing tail's continuation bytes
rendered literally after reveal (~24% of the fuzz corpus). The emulator
now tracks the unparsed trailing partial at ingest
(terminal-partial-escape-tail.ts, committed post-parse like the mouse
mirror) and ships it as TerminalSnapshot.pendingEscapeTailAnsi.
applyMainBufferSnapshot writes it LAST, after POST_REPLAY reset — any
later ESC would abort the dangling sequence. Seq accounting is unchanged:
the tail is a suffix of bytes the snapshot seq already counts, so
reconcile slicing needs no adjustment.

Fuzz suites: unskip the Bug B/C repros (fixed on this branch) and the new
D/E repros; remove the B/C/E tolerance predicates so regressions fail
loudly. Only Bug A (upstream wrap null-cell) stays tolerated + counted.
Green at FUZZ_ITERATIONS=2000 (fidelity) and 1000 (reconciliation).

* Cut the hidden-restore flood feedback loop (A) + query carve-out on drops (B)

(A) Under a foreground flood, the hidden-output-restore loop re-fetched
snapshots endlessly: each synchronous applyMainBufferSnapshot starved ACK
processing, main pinned at the in-flight cap, dropped at the pending cap,
and every droppedOutput/modelRestoreNeeded marker re-armed another
restore until the flood ended (rc.7.perf DSR timeouts).
- Restore loop: a foreground live-chunk queue overflow now abandons the
  restore immediately (the stream is outrunning snapshot fetch+replay),
  with a 3-iteration hard cap + lifecycle warn as backstop.
- Re-arm gate: drop markers/sentinels and reconcile seq-gaps on a visible
  pane during its own in-flight/just-abandoned restore no longer re-arm;
  live bytes write through and ONE deferred repaint (2s after the last
  backpressure signal) heals the gap. Hidden-pane gate semantics are
  unchanged.
- Query salvage: discarding queued restore bytes (overflow/refetch) now
  extracts DSR/CPR/DA/OSC-color queries and replays them to xterm so
  replies still flow.

(B) Main-side: dropOversizedPendingPtyData carves reply-eliciting query
sequences out of the dropped buffer (and out of post-drop latched data,
bounded) and ships them on the droppedOutput sentinel, so DSR probes
survive bulk drops. Query scanning moved to
src/shared/terminal-reply-query-extraction.ts, shared verbatim with the
renderer's hidden-startup query extraction.

* ACK terminal output at parse-drain, not dispatcher enqueue (C)

received", never "bytes parsed". Under flood the renderer write queue
grew unbounded behind instant ACKs; main saw no backpressure, crossed
the pending cap, and bulk-dropped output (rc.7.perf DSR timeouts).

Crediting is now parse-deferred: each delivery carries a fire-once
credit (deliverPtyDataWithDeferredAck); the pane's first scheduler write
claims it (writeTerminalOutput.ackCredit) and the output scheduler fires
it when the bytes are consumed — after terminal.write in the
parse-clocked drain, or on ANY discard path (backlog cap replacement,
discardTerminalOutput, disposed-terminal drops, flush recovery).
Deliveries that never reach the scheduler (reconcile drops, restore
queueing, pre-mount eager buffer) settle at handler return, so the
invariant holds: every delivered chunk credits exactly once, parsed or
discarded. E2E ack-gate hold/release and delivery-resync semantics are
unchanged (all crediting still routes through ackPtyData).

Main-side equilibrium: with ACKs at parse cadence, in-flight becomes
true backpressure — pendingData stays near the 256KB producer-pause
watermark, far under the >=2MB drop cap, so bulk floods block the shell
(node-pty pause) instead of dropping.

* Synthesize salvaged query replies directly instead of replaying into xterm

The 10MB dev bench proved the write-back salvage insufficient: a
pending-cap drop always triggers a snapshot restore, whose replay guard
swallows xterm auto-replies and whose discardTerminalOutput races away
still-queued query writes — the salvaged DSR died both ways and the
fence still timed out.

Salvage now answers directly on the input path (immune to both): CPR
(CSI 6n) from the live buffer via transport.sendInput, DA1 with the
renderer's canned response, OSC color probes via the existing direct
responder. Rare queries (DECRQM, DA2) keep the best-effort xterm
replay.

* Fix Windows update-relaunch killing the live terminal daemon

On a Windows update relaunch the daemon can be wedged past every RPC
budget (final checkpoint flush + installer/AV disk pressure), so the 3s
health check AND the 5s session-list hello both time out while sessions
are still alive - and the launcher failed closed, killing the daemon and
every terminal session it owned.

- Adopt an unresponsive daemon whose pipe still accepts a raw
  connection; a new rejected health state keeps replacing daemons that
  answered and refused the handshake (never adoptable).
- Give Windows pid files a real startedAtMs (daemon self-reports it in
  the ready IPC message) and verify it via CIM CreationDate piggybacked
  on the existing command-line query, so the pid-recycling guard is no
  longer inert on win32.
- Only delete legacy daemon pid/token files when the pid-file process is
  provably dead; deleting a live daemon''s token made its sessions
  permanently unadoptable after a protocol bump.
- Capture agent resume records every 60s in the renderer (skipping
  unchanged records) so hard kills still leave a fresh resume record.

* Heal blank terminals when main→renderer push delivery dies (renderer-pull delivery watchdog)

Field evidence (v1.4.121-rc.0 debug snapshot, 2026-07-06): a wedged window
held 530,115 un-ACKed in-flight chars — one PTY pinned at the 512KiB per-PTY
high water plus a fresh terminal's 245-char prompt that was sent and never
consumed — while the user ran the snapshot over invoke from that same window.
Main→renderer push delivery (pty:data and every sibling channel) was dead;
renderer→main→renderer invoke was alive. Upstream precedent for
one-directional IPC death: electron#37067 (suspected Mojo pipe disconnect,
stalled as need-info). Every terminal goes blank, new terminals are born
blank, and only a renderer reload recovered.

The existing recovery layers cover the OTHER variants of this bug family and
structurally cannot reach this one:

- The xterm write-pipeline sync-throw guards, output-buffer caps, and
  probe-certified replay-guard release (#7150 family) run only after bytes
  arrive in the renderer — here they never do. (The pending cap did work as
  designed in the field: ~2.1MB pendingDroppedChars, bounded main heap.)
- Cumulative ACKs self-heal lost ACK messages and the solicited delivery
  resync reconciles verified totals (4647df86a; #7260 on main) — but the
  resync probe, the powerMonitor wake relay, and the droppedOutput restore
  markers all ride main→renderer push, the direction that is dead. The
  probe's unanswered path deliberately only logs.

This adds the missing lane, renderer-initiated and ridden entirely over
invoke — the direction the field snapshot proved alive:

- terminal-delivery-watchdog.ts: 15s heartbeat, free while output flows.
  Hot-path cost is one Map upsert per received chunk; a tick does no IPC
  unless the terminal plane was silent for the whole interval and a PTY
  still expects delivery. Two consecutive silent ticks with main reporting
  ACK-starved in-flight confirm the wedge; heals are one-shot per 60s
  cooldown so a persisting wedge cannot repaint-storm.
- pty:reportRendererDeliveryState (invoke): always max-merges the renderer's
  cumulative processed totals (a free extra repair lane for the lost-ACK
  variant); with heal:true — and only after main has itself seen ≥10s of ACK
  silence — writes off bytes the renderer provably never received
  (received ≤ acked < sent; a received-but-unparsed backpressure window is
  never written off), drops that PTY's pendingData (snapshot covers
  everything ≤ markerSeq, hidden-drop parity), credits provider flow
  control, and returns restore markers in the reply.
- The renderer re-attaches all push listeners (cures a detached-listener
  variant outright; a safe no-op against a dead channel) and routes the
  pulled markers through the existing pty:modelRestoreNeeded machinery —
  panes repaint from the main-owned buffer snapshot with zero push
  delivery involved.
- Field discrimination built in: the heal warn logs
  ipcRenderer.listenerCount('pty:data') (listener detached vs channel dead)
  with the full delivery snapshot, so the next occurrence names the root
  cause without asking the user to run anything in a console.

Repro harness: the exposeStore-gated __terminalDeliveryWatchdog hook
blackholes pty:data ahead of the dispatcher — the field failure in
miniature (no receive count, no ACK credit, no dispatch).
terminal-push-delivery-loss-recovery.spec.ts proves the wedged output
repaints while the blackhole is still engaged and live flow resumes after
release, with no reload. Unit suites pin the watchdog state machine
(zero IPC under flow, two-tick confirm, cooldown), the dispatcher reattach
seam, and the main-side write-off semantics.

Perf: nothing added to main's send/flush path; the renderer data path gains
one integer/Map update per chunk; idle cost is one ~100-byte invoke per 15s
only during total terminal silence. Terminal perf e2e suite (typing
latency, redraw freeze, output scheduler, hidden TUI restore, artificial
opencode load) passes on this change; no watchdog activity occurs under
ack-gate pressure scenarios because receive-progress gates the heartbeat.

* Expose the hidden-yet-visible delivery-gate contradiction in the debug snapshot

The v1.4.124-rc.2.perf blank-terminal field snapshot showed a different
state than the v1.4.121 transport wedge: no delivery gating at all
(ackGatedFlushSkipCount 0, in-flight 38KB, far under every cap) but TWO
ptys hidden-delivery-gated with 78MB dropped as hidden. The aggregate
counters cannot say whether the pane the user was staring at was one of
the gated ones — the one number that separates "normal background
dropping" from "main is starving a visible pane because the reveal
unmark never fired".

Add hiddenDeliveryGatedVisiblePtyCount / hiddenDeliveryGatedActivePtyCount
(overlap of the gate's hidden set with the renderer's visible/active
reports — a contradiction that must be zero) to the delivery debug
snapshot, and a once-per-minute warn when hidden-gated bytes are dropped
for a pty the renderer reports visible or active, with the full snapshot
attached. Zero cost outside the debug read and the already-dropping path.

* Unlatch the hidden-delivery gate when user input disproves a stuck document.visibilityState

macOS occlusion tracking can wedge document.visibilityState at 'hidden'
after display sleep and never fire another visibilitychange. The hidden-
delivery gate then keeps dropping renderer-bound bytes for panes the user
is looking at (field snapshot 2026-07-06, v1.4.124-rc.2.perf: 78MB dropped
across 2 pane-level-visible ptys with a fully healthy transport), and every
recovery path (window focus, system-resume relay, backlog recovery) re-ran
syncHiddenRendererPtyDelivery only to recompute the same stale predicate —
nothing could ever clear the gate. The user sees a frozen terminal; typing
echo is dropped in main; only a reload recovers.

Real user input while the document claims hidden is a physical
contradiction: keystrokes and clicks only reach a focused, on-screen
window. stale-document-visibility.ts latches that proof, runs each pane's
existing visibilitychange resync (gate unhide + hidden-output snapshot
restore), and hands authority back to the occlusion tracker on the next
genuine visibilitychange. No timers; the failure bias is safe — a wrong
latch can only restore pre-gate delivery cost, never drop bytes. Hot path
unchanged: the foreground predicate still returns on the same single
comparison while the document is visible.

tests/e2e/terminal-stuck-occlusion-recovery.spec.ts pins the wedge
(visibilityState pinned hidden -> output dropped, not painted; the
hiddenDeliveryGatedVisiblePtyCount field discriminator reads >0) and the
recovery (one Shift keypress repaints the missed output from the main-owned
snapshot, no reload, while visibilityState still reads hidden). Negative
control verified: the spec fails without this fix. Typing-latency perf
gate passes; terminal-pane unit suites 366/366.

* Add a one-paste terminal freeze report: __orcaTerminalFreezeReport()

Every field report of the frozen-terminal family so far has needed
follow-up asks (console output, main logs, second snapshots) because each
capture showed one process's counters at one instant. This makes a single
DevTools command sufficient: `await window.__orcaTerminalFreezeReport()`
returns renderer state (document.visibilityState + the stale-visibility
override, pty:data listener count, delivery-watchdog totals), main's debug
snapshot extended with a per-pty delivery table (sent/acked/pending, hidden
vs visible-set membership, last send/ACK ages, window focus flags, power
suspend/resume ages, app version), and bounded breadcrumb rings from BOTH
processes recording the transitions that matter: gate marks/unmarks,
visibilitychange and stale-visibility latches, watchdog stalls and heals,
restore markers, heal write-offs, and renderer lifecycle resets (so "user
already reloaded" is visible in the history).

Costs stay off the data path: breadcrumbs record only rare transitions into
a 100-entry ring with same-kind coalescing (a flood costs one slot per
second); the per-pty table is built only when the snapshot is read; the
per-send bookkeeping adds one Date.now() to existing accounting writes. Pty
ids are redacted to their `@@` suffix because daemon session ids embed
worktree paths. The report assembles over invoke IPC — the direction proven
alive in every observed wedge — and a failing invoke is captured as data
instead of sinking the report.

The stuck-occlusion e2e now also pins the report end-to-end: after the
wedge + keystroke recovery, the report must carry the stale-visibility
latch and gate transitions in the renderer ring, gate-mark/unmark in main's
ring, and a populated per-pty table. Suites: pty.test.ts 258, terminal-pane
1705, shared ring 5; typing-latency perf gate passes.

* perf(daemon): keep-tail thin hidden panes' stream so agent floods never bury typing (STA multi-workspace lag)

Hidden panes are exempt from pendingData flow control (main gate-drops
their bytes after ingestion), so N background agents ran unbounded ahead
on the one shared daemon->main stream socket (measured 192MB user-space
backlog) and visible-pane echo waited FIFO behind it — typing appeared
seconds late whenever several agents burst on a loaded machine
(8x512KB/s + 12 CPU spinners: p50 293ms fix-off; 12x1MB/s: 6.1s).

Mechanism (replaces producer pacing — no reveal catch-up, ever):
- Shallow socket write gate (128KB) + per-session fairness bypass bounds
  echo latency by construction; kernel-flush refill sentinel keeps held
  bulk draining at full speed (drain-only refill capped at ~8MB/s).
- Backgrounded sessions' queued output is keep-tail dropped (newest
  512KB kept, in-order dataGap replaces the middle); a ~2MB GLOBAL
  budget shrinks per-session keep-tails (floor 64KB) so a worktree
  switch never waits behind the aggregate. Reply-eliciting query bytes
  (DSR/DA/OSC probes) are salvaged from dropped spans.
- Notifications are structurally lossless: the daemon runs the same
  shared scanners main uses (bell/OSC 133/pr-link/2031) over every byte
  BEFORE drop decisions and relays facts in byte order; ordered
  background markers hand scan authority back and forth, seeded with the
  emulator's partial escape tail so a sequence split across the handoff
  neither phantom-fires nor goes missing. Titles/agent-status stay
  main-side (kept-tail convergent).
- Main: background = hidden AND no remote view subscriber (a live
  mobile/web view is never thinned); on dataGap main resets cross-chunk
  parse carries, drops the headless mobile mirror, and reuses the
  hidden-drop model-restore marker.

Wire: three new stream events, tolerated within protocol v19 (old mains
ignore unknown events; old daemons never see the trigger). Kill
switches: ORCA_DAEMON_BACKGROUND_STREAM_DROP=0,
ORCA_DAEMON_SHALLOW_SOCKET_GATE=0.

A/B (pnpm bench:multi-workspace-typing): 8x512KB/s + 12 CPU workers
p50 293ms/p90 647ms -> 15/21ms (= baseline); 12x1MB/s 6,146ms -> 20ms;
light loads unchanged; zero missing echoes. Latin hidden-restore e2e
green (probe-verified aggregate-drain root cause). New deterministic
repro harness: tests/e2e/terminal-multi-workspace-typing-latency.spec.ts
+ CPU pressure workers.

* diag(terminal): breadcrumb WebGL context-loss/atlas + wake triggers into freeze report

Silent instrumentation (memory ring only, no new console lines) so the next
post-wake garble report attributes itself. Adds:
- shared/terminal-webgl-diagnostics.ts: lib-safe sink so pane-webgl-renderer
  (lib) can record without importing the components-layer ring; wired to the
  ring in terminal-freeze-breadcrumbs.
- webgl-context-loss crumb at onContextLoss, webgl-atlas-reset crumb at the
  atlas registry reset — the pair that distinguishes 'atlas corrupted' from
  'missed repaint'.
- wake-recovery:<source> crumb (focus/visibilitychange/system-resumed) with the
  clearGlyphAtlases decision; source in the kind so distinct triggers don't
  coalesce.
- per-pane WebGL state (getAllPaneRenderingDiagnostics) in the freeze report.

Gates: typecheck 0 errors; terminal suites 328 files pass; oxlint clean.

  toHaveBeenCalledWith assertions.

  registerRemoteTerminalViewSubscriber (subscribe path calls it now, erroring
  before snapshot serialize); added the stub used by sibling multiplex tests.

* Fix hidden/parked split-pane exit stranding ghost or resurrected panes

Deterministic e2e repro of the field 'ghost blank pane' incident (a
closed/finished setup-split leaf persisted in root with no binding and
remounted as a permanently blank pane) found two teardown gaps at the
hidden-view parking boundary:

1. The kept-exit guard ('freshly split pane can lose its newborn PTY
   during setup') fired for HIDDEN panes. The hidden-delivery gate
   withholds their bytes, so a hidden split always looks output-less and
   its dead pane was kept — a binding-less ghost that dead-session
   reconcile can never reach (no PTY id to prove dead). The keep is a
   visible-failure UX; gate it on isVisibleRef and close hidden panes.

2. A PTY exit landing while the tab is PARKED reached only the parked
   watcher's exit sidecar (hosts' onPtyExit requires a mounted
   TerminalPane), which only disposed the watcher. The leaf's stale
   binding then reattached on reveal and the daemon re-created the
   exited session id as a fresh shell — silent pane resurrection. The
   sidecar now collapses the dead leaf out of the stored layout via
   detachTerminalLayoutLeaf (the observed-exit teardown's data half).

New e2e suite terminal-pane-close-layout-consistency.spec.ts sweeps
close/shell-exit at every hidden/park lifecycle phase and asserts
leaves(root) == bindings == live panes; all 7 scenarios pass. Unit
regressions added for both fixes.

cbd06a7671 feat(tab-bar): add shortcut to open commands for active tab group (#6325)
* Add keyboard shortcut to toggle the Quick Commands menu

- New `tab.openQuickCommandsMenu` keybinding action (no default binding)
- TabBarQuickCommandsMenu listens for the binding and toggles open/closed
- Scoped to the active tab group naturally since the component only mounts when its group is focused

* Show keyboard shortcut in Quick Commands menu trigger tooltip

* Add tests

* expand tests

* Expand keyboard toggle to call handleOpenChange and skip repeated keys

- Replace `setMenuOpen` toggle with `handleOpenChange(!menuOpen)` so closing
  via keyboard runs the same reset logic (query, focus frame, value override)
- Guard against key-repeat events to prevent rapid toggling on held key
- Wrap `handleOpenChange` in `useCallback` so it's stable enough to include
  in the `useEffect` dependency array without causing spurious re-registrations
- Update tests to reflect that re-running the effect between presses is
  required for the close path, and add a repeat-event test

* Add docstring to withShortcutHint func

* review: harden quick commands menu shortcut

Brennan BensonandNeil 60412362a1 fix(win): stop renderer crash-loop with an auto-recovery circuit breaker (#6856)
A deterministic per-load renderer fault (bad GPU driver, corrupt chunk,
AV interference) crashes on every load. Orca auto-reloads recoverable
renderer deaths after 250ms, so without a limit it reloads every
~0.25-1.3s forever — the Windows clusters F0BDRAZN55L (launch-failed
exit 18, bootstrap loop ~1.3s) and F0BDPCL93UM (ACCESS_VIOLATION on
Win10 1909, ~0.8s loop). shouldRecoverRendererAfterProcessGone only
gated integrity-failure/launch-failed, never 'crashed'/'killed'.

Add a rolling-window circuit breaker (3 recoveries / 60s) consulted at
the reload point in createMainWindow. When it opens, Orca stops
auto-reloading, records a renderer_recovery_circuit_breaker_open
breadcrumb, and shows a native Reload/Quit prompt (the renderer is dead,
so a main-process dialog is the only available surface). The window is
NOT reset on did-finish-load: a crash loop renders on every cycle before
dying, so stale attempts must age out by time instead.

Covered by renderer-recovery-circuit-breaker.test.ts (pure helper) and a
createMainWindow.test.ts integration test that drives the loop and
asserts reloads stop after the limit.

7e6cc9ab49 fix(window): remove double title bar on Linux (#5726)
* fix(window): remove double title bar on Linux

On Linux the BrowserWindow titleBarStyle fell through to undefined, so
the native WM title bar stayed and stacked on top of Orca's own
renderer-drawn titlebar — two title bars. macOS (hiddenInset) and
Windows (hidden) already suppress the native one.

Drop the native frame on Linux (frame: false) and extend the renderer's
Windows-only custom-titlebar branches (logo/menu anchor, app-name
hiding, window-controls spacer + CSS vars, and the WindowControls
min/max/close cluster) to Linux via a shared `hasCustomTitleBar` flag,
so Linux gets one title bar with working window controls — matching the
Windows custom-titlebar path.

Fixes #5724

bc1ba6dc72 fix: pr-bug-scan validated finding from #2504 (#2548)
* fix: address pr-bug-scan validated finding from #2504

Narrowed App.tsx early return so it only suppresses chords the floating panel actually claims (Cmd+T/W, Cmd+Shift+B/M); B/L/Shift+E/F/G now reach app branches.

* Let floating terminals receive shell control chords

- Track floating xterm focus in the main process so Ctrl+B/Cmd+B and
  sidebar-adjacent chords can pass through to SSH and tmux
- Share renderer shortcut targeting logic for floating panel shortcuts
- Cover focus routing and shortcut ownership with tests

NeilandNeil Parker 7c45ef45b4 feat(windows): custom title bar with renderer-drawn window controls (#1583)
Replace the default Windows native title bar with a custom renderer-drawn
titlebar to match the macOS experience:

- Set titleBarStyle:'hidden' on win32 to remove the OS chrome
- Add min/max/close buttons (Fluent-style SVG) fixed to the top-right corner,
  rendered last in DOM order so they're never blocked by -webkit-app-region:drag
- Route close through IPC (window:close-requested) so the terminal-running
  confirmation guard stays active; minimize/maximize via window:minimize and
  window:maximize IPC channels
- Add maximize state sync (window:maximize-changed) so the restore icon shows
  correctly
- Add Orca logo + ··· application-menu button on the left in place of the bare
  pl-2 spacer; ··· calls Menu.getApplicationMenu().popup() replicating Alt-key
  reveal
- Add window-controls-titlebar-spacer to reserve 138px on the right of the
  full-width titlebar so content isn't obscured by the overlay

JinjingandOrca db956ed6db fix(window): prevent teardown resize events from clobbering saved window bounds (#1269)
On close/quit (especially auto-updater relaunch via quitAndInstall),
Electron/OS emit resize/move/unmaximize while the window is torn down.
The debounced persistence was capturing those near-minimum bounds, so
the next launch came up at minWidth x minHeight.

- Freeze bounds persistence on window 'close' and app 'before-quit'
  (updater strips the window 'close' listener before quitting, so
  the app-level latch is needed as a second line of defense).
- Release the freeze on will-prevent-unload so aborted Cmd+Q keeps
  saving bounds.
- On restore, discard saved bounds at/below the min dimensions to
  recover users who already persisted corrupt bounds.

f5ad7aa249 feat(settings): import Ghostty config with preview, color overrides, opacity and blur (#1001)
* feat(settings): add Ghostty config import

Add safe one-shot Ghostty import with preview and success summary,
and probe documented Ghostty config paths before applying changes.

Refs #958

* chore(git): ignore atl artifacts

* feat(settings): map font-weight, cursor-blink and focus-follows-mouse from Ghostty

Adds three safe direct-mapping Ghostty keys that have clear equivalents
in GlobalSettings: font-weight, cursor-style-blink, and focus-follows-mouse.

Refs #958

* feat(settings): expand Ghostty import to support colors, opacity and option-as-alt

- Add TerminalColorOverrides type grouping 21 optional xterm ITheme fields
- Add terminalBackgroundOpacity, terminalPanePaddingColor, terminalPaddingBalance
  to GlobalSettings
- Extend parser to collect repeated keys as string[] (needed for palette lines)
- Map background-opacity, background, foreground, cursor-color,
  selection-background/foreground, palette (0-15), window-padding-color,
  window-padding-balance, macos-option-as-alt in mapper
- Merge terminalColorOverrides into xterm ITheme at theme resolution; apply
  opacity as rgba() with allowTransparency enabled
- Accept hex colors with or without leading # (Ghostty omits it)
- Fix preview diff to use deep equality for object values so already-applied
  color overrides no longer reappear on next import

* feat(settings): support background-blur-radius and window-padding-color extend in Ghostty import

- Map background-blur-radius > 0 to windowBackgroundBlur: true; apply
  vibrancy on macOS and backgroundMaterial acrylic on Windows at window
  creation (blur requires restart — no hot-reload IPC exists)
- Accept window-padding-color = extend/background as valid Ghostty values;
  both map to default Orca padding behavior (undefined field) instead of
  landing in unsupportedKeys
- Split mapper.test.ts into domain-scoped describes to stay under 300-line limit

* feat(settings): add Window section to Terminal settings panel

Expose terminalBackgroundOpacity, windowBackgroundBlur, terminalPaddingBalance,
terminalPanePaddingColor, and terminalColorOverrides in the settings UI so
imported Ghostty values can be viewed and changed manually.

- New TerminalWindowSection component (extracted from TerminalPane to stay
  under the 400-line limit)
- Collapsible color overrides sub-section with ColorField for all 21 xterm
  ITheme fields grouped as base, ANSI normal, and ANSI bright
- Reset button clears all color overrides at once
- Window blur toggle shows restart-required note (blur applies at window
  creation, no hot-reload IPC exists)
- Search entries added for all new controls

* feat(settings): expand Ghostty import with scrollback, padding, divider, cursor and word-chars keys

Map 9 additional Ghostty keys to Orca settings:

- split-divider-color → terminalDividerColorDark + terminalDividerColorLight
  (single value applies to both; Ghostty has no dark/light distinction)
- unfocused-split-opacity → terminalInactivePaneOpacity (direct float 0-1)
- scrollback-limit → terminalScrollbackLimit; applied to xterm scrollback option
- window-padding-x / window-padding-y → terminalPaddingX/Y; applied as CSS
  vars --pane-padding-x / --pane-padding-y in terminal.css
- cursor-text → terminalColorOverrides.cursorAccent (xterm ITheme field)
- bold-color → terminalColorOverrides.bold (persisted; xterm ITheme has no
  bold field yet — stored for future xterm upgrade)
- cursor-opacity → terminalCursorOpacity; blended into cursor rgba at theme
  resolution time
- selection-word-chars → terminalWordSeparator; applied to xterm wordSeparator
- mouse-hide-while-typing → terminalMouseHideWhileTyping field added; renderer
  application deferred (needs per-pane disposable + global mousemove listener)

* feat(settings): expose new Ghostty-imported settings in Terminal Settings UI

- Window section: scrollback limit, horizontal/vertical padding, hide mouse
  while typing toggle, cursor text and bold color in Color Overrides
- Cursor section: cursor opacity NumberField
- Advanced section: word separators text input
- Search entries added for all new controls
- terminalDividerColorDark/Light and terminalInactivePaneOpacity skipped —
  already present in Theme and Pane Styling sections respectively

* feat(terminal): implement mouse-hide-while-typing per pane

Register terminal.onData → cursor:none and mousemove → restore, scoped to
the pane container element. Uses the existing IDisposable per-pane pattern
(same as selectionDisposablesRef). Cleans up on pane close and effect teardown.

* refactor(settings): address ghostty import code review findings

- Centralize GhosttyImportPreview type in shared/types (remove duplicate from mapper)
- Fix parser to strip inline comments without breaking hex color values (#1a1a1a)
- Extract HEX_COLOR_RE to shared/color-validation to avoid duplication
- Remove redundant Number.isNaN checks after Number.isFinite (4 sites)
- Replace unsafe catch-all assignment with explicit font-family branch
- Migrate 280-line if-chain in mapGhosttyToOrca to FIELD_PARSERS registry
- Add human-readable setting labels in GhosttyImportModal via setting-labels map
- Add clarifying comment in index.ts re JSON.stringify undefined behavior

* fix(settings): harden ghostty import from judgment-day review

- Surface readFile errors in GhosttyImportPreview.error instead of
  showing misleading 'No config found' on permission denied
- Guard handleApply against double-apply when already applied
- Strip surrounding quotes from parsed config values (font-family)
- Return null from palette handler when all entries fail validation
- Inform user when background-blur-radius radius is not preserved
- Add valuesEqual key-order stability via stableStringify
- Normalize hex colors to #-prefixed format across all color mappers
- Reject blank values before numeric parsing (Number('') === 0 trap)
- Remove selection-word-chars mapping (inverted xterm semantics)
- Guard window-padding-x/y against negative integers
- Reactive mouse-hide-while-typing on existing panes when setting toggles
- Merge terminalColorOverrides on import instead of replacing

* fix(ghostty): drop broken imports, tighten parsing, prompt restart for blur

Review found three high-impact issues in the Ghostty import: scrollback-limit
semantics are inverted/rescaled (Ghostty is bytes with 0=unlimited, xterm is
rows with 0=disabled), and window-padding-color + window-padding-balance set
CSS custom properties (--pane-padding-color, --pane-padding-balance) that
have no consuming rule anywhere in the tree — so users confirming "changes"
to those keys would see nothing happen.

Because none of the three keys have a safe mapping today, drop them from the
import and remove the dead UI controls + GlobalSettings fields + CSS var
plumbing. The mapper now lists them as unsupportedKeys alongside the
existing window-decoration / keybind / custom-shader entries.

Other fixes in the same review:

- allowTransparency now clears when background-opacity returns to 1 (prior
  code only ever set it to true, leaving a stale flag with measurable render
  cost).
- background-blur-radius = 0 no longer emits a misleading "radius value not
  preserved" note (0 cleanly maps to blur=false with no radius to lose).
- Add a 1 MB size cap on the config read so a pathological or symlinked file
  cannot OOM the main process.
- Make handleApply async and surface IPC errors inline in the modal instead
  of flipping straight to "Import complete" on failure.
- Type settings.previewGhosttyImport as Promise<GhosttyImportPreview> in
  preload so shape drift is caught at compile time.
- Make stableStringify recursive so future nested settings round-trip
  cleanly through valuesEqual.
- Restrict window-padding-x/y and background-blur-radius to decimal ints;
  prior code accepted exponent notation (1e10 sails through Number.isInteger)
  and would have landed absurd values in the store.
- Window blur now shows a "Restart required" banner with a Restart now
  button when the setting differs from the mount-time snapshot, mirroring
  the ExperimentalPane daemon pattern. Blur only applies at BrowserWindow
  creation on macOS/Windows.

* feat(settings): move Ghostty import trigger to Terminal section header

Per review feedback: the "Import from Ghostty" row was taking its own slot
in the Terminal settings list alongside real configuration sections. Move
the trigger into the Terminal section's header (upper-right corner) as a
headerAction, next to the Terminal heading — it's a one-shot action, not a
setting.

- SettingsSection gains an optional `headerAction` slot rendered to the
  right of the section title/description.
- The useGhosttyImport hook is lifted from TerminalPane into Settings.tsx
  so the section header button (owned by Settings.tsx) and the modal
  (still rendered inside TerminalPane) share one state instance.
- TerminalPane drops its own "Import" section + the TERMINAL_GHOSTTY_IMPORT
  search entry group is no longer referenced there.
- Button carries the official Ghostty mark as a 16x16 icon so it reads
  clearly as a cross-app import even before users parse the label.

useGhosttyImport now accepts `GlobalSettings | null` so the parent can call
it above the pre-load spinner guard without violating hook ordering; the
apply path no-ops until settings arrive. Related test file updated to
pass the new `ghostty` prop and to assert the trigger is *not* rendered
inside TerminalPane anymore.

Jinjing 2688c0fee3 feat(editor): preserve Cmd+B for bold in markdown editor (#802)
* feat(editor): preserve Cmd+B for bold in markdown editor

Carve out bare Cmd/Ctrl+B from the main-process before-input-event
interceptor when the TipTap markdown editor is focused, so its bold
keymap can run instead of toggling the left sidebar. Focus state is
mirrored from renderer to main via a one-way IPC send, with default-deny
resets on crash/navigate/destroy and sender validation so only the main
window's webContents can mutate the flag.
