Jinjingandbbingz 1d2aaf1bf5 Fix recipe serve desktop promotion (#8646)
* fix(runtime): preserve terminals during headless desktop activation

* rm design doc

* Fix desktop activation launch ordering and blocked-window status resolut

- Check desktopWindowStatus before spawning the Orca app so a blocked
  runtime no longer launches a doomed second instance.
- Reuse resolveDesktopWindowStatus for remote runtime status so it
  honors the same authoritativeWindowId fallback as local status.
- Re-check the authoritative window at spawn time instead of trusting
  a possibly-stale snapshot, since it can be destroyed mid-await.
- Harden the e2e activation spec against silent spawn failures.

Silently swallowing chmod failures let installs proceed with a

Jinjing 52388c1ab7 Fix worker done pane identity (#8473)
* fix(orchestration): bind lifecycle sends to dispatched pane

* fix(orchestration): bind injected worker messaging

* Fix worker_done pane identity gating and rename SSH linear CLI files

- Lifecycle reconciliation now returns an explicit `rejected` action
  (instead of `ignored`) for persisted sender_not_assignee markers, and
  only treats a payload's `_orcaLifecycleRejection` as trusted state
  when it exactly matches that reserved shape, preventing caller-
  supplied markers from spoofing a rejected send as success.
- SSH legacy fallback CLI now fails closed with
  `no_active_sender_terminal` when a worker_done/heartbeat send has no
  resolvable sender identity, rejects mixed raw/structured payload
  flags, and reconstructs structured lifecycle payload fields
  (task/dispatch id, files-modified, report-path, phase) instead of
  dropping them — extracted into ssh-remote-orchestration-send.ts.
- Renamed ssh-remote-linear-argument-error.ts to
  ssh-remote-cli-argument-error.ts since RemoteCliArgumentError is now
  shared beyond the Linear CLI.

* Add re-read logging for already-converted lifecycle rejections

Send-path reconcile converts worker_done/heartbeat rejections with a
no-op logger, so the coordinator's later re-read is the only chance
to surface the rejection message. Log it there instead of dropping it.

* feat(ssh): support file transfers over system ssh

* fix(ssh): harden system file transfers

* test(runtime): stub getRepo in headless mobile tab cwd test

The mobile-session selector validator (getValidatedExplicitWorktreeIdSelector,
from main) calls this.store?.getRepo to reject repo ids passed as worktree ids.
The store stub only implemented getWorkspaceSession, so the guarded call threw
'getRepo is not a function' once main merged into this branch. Add a getRepo
that returns null (wt-1 is a worktree, not a repo).

e84a8ddec9 Terminal performance initiative: pipeline fixes + term-speed-2 revival + PTY flow control (integration branch) (#7214)
* Skip legacy hidden skip grammar assertions

* Fix hidden TUI snapshot test setup

* Fix sleep wake history test contract

* Fix hidden delivery startup gate helper

* Fix hidden Latin skip branch predicate

* Fix hidden synchronized split-boundary replay

* Stabilize remote runtime mixed subscription test

* Keep hidden startup query parser active during window

* Stabilize raw emoji golden restore width

* Stabilize raw emoji golden fixture completion

* Keep terminals responsive under agent output load

* Add frozen-terminal repro harness and silent-drop regression tests

Investigation harness for the frozen-terminal reports (Discord
#performance, issue #2836): pane shows content, shell alive, daemon
output.log flat while typing.

- 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

The previous stall watchdog blindly released the input guard after 10s.
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.

* Record baseline + decomposition findings in initiative plan

* 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.

* Findings: 51x loss attributed to O(tail) retained-tail redraw path in main onPtyData

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.

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

* 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.

green (1 pre-existing WSL failure unrelated).

* 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.

* VS Code head-to-head: Orca beats/ties 5 of 6 metrics (16x idle, 5x styles-stress, better p99); load p50 gap attributed to ACK window + timer-clamped drain cadence

* 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
notes/garble-fuzz-divergences.md. Seed 113 (handoff's DECSC/DECRC case) does not
diverge on the current harness. No production code changed.

* 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).

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

* 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.

- Fidelity suite: add snapshotHasSelfCancellingBoldReset (Bug B) and
  isMarginWrapPendingCursorOffByOne (Bug C) predicates so the corpus tolerates +
  counts them like Bug A. FUZZ_ITERATIONS=2000 is now green (~113s) and fails
  only on genuinely new divergences; each tolerance keeps its <50% degeneracy
  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.
- Notes updated: every bug class is both pinned (skipped repro) and tolerated in
  its corpus; combined default runtime ~19s.

* Keep RC update checks off perf prereleases

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

* 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)

The renderer credited main's per-PTY in-flight window the moment a
pty:data chunk entered the dispatcher, so the 512KB window meant "bytes
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.

* 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.

Three pre-existing perf-branch test failures (red before the latest main

  pty.ts installPowerSignalBreadcrumbs now calls on registerPtyHandlers.
  Added powerMonitor:{on:vi.fn()} to match pty.test.ts.
- runtime-terminal-stream.test.ts: onSnapshot now receives a second
  { pendingEscapeTailAnsi } meta arg (#7329); updated the three exact-arg
  toHaveBeenCalledWith assertions.
- terminal-multiplex-escape-tail.test.ts: stubRuntime missing
  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.

BingZandJinwoo Hong 96d1fa1d62 fix(grok): clipboard, native chat, hooks, sessions, ConPTY KKP (#7944)
* fix(grok): restore clipboard and native-chat parity

Grok CLI already supports argv prompts, OSC 52 copy, and image paste chips.
Orca was blocking those paths: stdin-after-start keystroke injection, OSC 52
writes default-off, image-attachment denylist, and native-chat allowlist.

- Launch Grok with positional argv prompts
- Default OSC 52 TUI clipboard writes on (still user-toggleable)
- Treat Grok as image-attachment capable
- Parse ~/.grok/.../chat_history.jsonl for native chat

OSC 52 clipboard *query* remains ignored by design (host clipboard exfil risk);
xAI docs only require OSC 52 write for remote copy.

* fix(grok): sync OSC 52 docs and locale catalog with default-on

Update terminalAllowOsc52Clipboard type docs for the true default, and
refresh locale strings so settings UI mentions Grok alongside other TUIs.

* fix(grok): tool hook matcher, StopFailure, previews, AskUser waiting

Grok tool-event matchers are real regexes; bare `*` failed as match-all.
Install `.*` for Pre/Post tool hooks, add StopFailure for API-error ends,
recognize Grok-native tool input keys, and map ask_user_question PreToolUse
to waiting with interactivePrompt (Kimi-style live card path).

* fix(grok): resolve chat_history under GROK_HOME and long-cwd layouts

Centralize Grok session path helpers so hooks and native-chat honor
GROK_HOME and find chat_history.jsonl by session id when the cwd group
is slug-encoded (encoded name > 255 bytes) instead of only
encodeURIComponent(cwd).

* fix(terminal): keep Kitty keyboard for Grok on Windows ConPTY

Local Windows ConPTY withholds KKP so CSI-u-blind CLIs (e.g. Antigravity)
keep Enter/nav working (#2434). Grok needs KKP for Ctrl+Enter interject and
modified-Enter newline chords; blanking the advertisement for Orca-launched
Grok left those actions broken.

- Prefer KKP when tuiAgent is grok despite ConPTY withhold
- Wire launchAgent from tab/startup into keyboard protocol options

* fix(grok): restore OSC52 default-off, split decoders, honor GROK_HOME hooks

- Keep terminalAllowOsc52Clipboard default false (clipboard exfil risk)
- Split transcript-line-decoders under max-lines without suppressions
- Install local Grok hooks under resolveGrokHomeDir() / GROK_HOME

* refactor(grok): share CLI home resolution

* fix(grok): harden terminal and native chat integration

* test(grok): align CI coverage with native chat support

2026-07-10 12:56:17 -07:00
Jinwoo HongandOrca 0784a7ea37 fix(ssh): bridge the full Orca CLI over the SSH relay instead of a hardcoded command switch (#7771)
The relay CLI shim on SSH remotes rejected every orchestration/mutation
command with 'Unsupported SSH Orca CLI command' because the host handled
relay CLI requests with a hand-rolled allowlist of five read-only-ish
commands. The host now runs the real bundled orca CLI entry (same entry
as the local shell command, via ELECTRON_RUN_AS_NODE) as a captured
subprocess, so remote invocations get the full command surface by
construction. Remote cwd is carried via ORCA_CLI_CWD so cwd-based
selectors (--worktree active) resolve against the caller's remote
directory; only Orca terminal-context env vars cross the bridge.

Host-interactive commands (serve, claude-teams, agent-teams-tmux) get a
targeted error, and the legacy in-process switch remains as a fallback
when the host CLI entry cannot be launched. Relay-side request timeouts
are raised to fit mutation and long-poll (--wait/--timeout-ms) commands,
and stdin forwarding now covers *-stdin payload flags.

Jinwoo HongandOrca ace196b08e fix(ssh): stop false "Remote connection dropped" after sleep/App Nap pauses (#7828)
* fix(ssh): guard mux dead-link detector against sleep/App Nap timer pauses

After system sleep or App Nap timer throttling, the first post-wake
timeout-check tick saw pre-pause keepalives as >20s stale and killed a
healthy link (false 'Connection timed out (no ack received)' ->
dispose('connection_lost') -> reconnect overlay churn). Track the last
tick time; when a tick gap far exceeds the interval, reset staleness
tracking, probe with a fresh keepalive, and let the next full window
make an honest liveness determination. A genuinely dead link is still
detected within ~25s after wake.

Also adds probeLiveness(timeoutMs): a keepalive round-trip primitive
that resolves true on the first frame of any kind, used by the resume
path to distinguish surviving links from dead ones.

Refs #7773

* fix(ssh): probe relay liveness on system resume instead of unconditional reconnect

powerMonitor 'resume' previously called connectionManager.reconnect()
for every active target, guaranteeing a teardown + reconnect overlay on
every wake even when the connection survived sleep. Now each session's
relay link is probed (keepalive round-trip, 5s timeout, one retry for
slow post-wake network); only targets whose probe fails are reconnected.
Dead-after-sleep connections still reconnect promptly. The 'suspend'
grace-time handling is unchanged.

* feat(relay): prefix relay.log diagnostic lines with ISO timestamps

The remote relay.log had no timestamps, which blocked correlating
reconnect flaps with user activity and sleep/wake windows while
diagnosing #7773. Daemon-mode diagnostic lines now carry an ISO
timestamp prefix ('<ISO> [relay] ...', grep-stable). Connect-mode and
orca-cli passthrough stderr is untouched since it goes back to the
app/user terminal and is parsed (handshake-mismatch detection).

The relay bundle is content-hashed at build time, so the versioned
install picks up the new relay automatically on next deploy.

* fix(ssh): re-check session identity before post-probe resume reconnect

The resume probe can take ~10s; if the user disconnected the target or the
session/connection was replaced during that window, reconnecting would
resurrect an intentionally torn-down connection (CodeRabbit).

Jinwoo HongandOrca 864594ffdd Fix SSH state for paired remote clients + complete target re-adoption sweep (STA-1468) (#7767)
* Sweep all persisted carriers of a removed SSH target id on re-adoption

reassignSshTargetId re-pointed repos and worktree metas but left the old
target id embedded in persisted session pty ids (ssh:<id>@@pty-N in tabs,
layouts, remoteSessionIdsByTabId), the startup reconnect list
(activeConnectionIdsAtShutdown, replayed via ssh.connect at boot — the
exact 'SSH target not found' in STA-1468), sleeping-agent resume records,
provisioned project host setups, sidebar host-scope arrays, and relay pty
leases. Any survivor resurfaces later as a failing connect or reattach.

New ssh-target-id-migration module re-points every carrier in one pass,
wired into reassignSshTargetId with per-carrier unit and store-level
round-trip tests.

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

* Bridge SSH connection state to paired remote clients

The SSH surface was desktop-only: ssh:state-changed went to the host's
own BrowserWindow and the web client's ssh API was a no-op stub, so a
paired client's reconnect overlay never learned the host connected and
its target labels stayed empty (STA-1468 — overlay stuck on 'please
connect' over a live terminal).

- New sshStateChanged runtime client event, emitted from broadcastSshState
  through OrcaRuntimeService onto the existing clientEvents stream.
- New ssh.listTargets / ssh.listRemovedTargetLabels RPC methods next to
  the previously unused ssh.getState / ssh.connect.
- Web preload now routes listTargets / listRemovedTargetLabels / getState
  / connect to the paired host's runtime RPC instead of stubbing them.
- useIpcEvents applies sshStateChanged on paired web clients through the
  same guarded path as desktop ssh.onStateChanged; desktop clients ignore
  the event since a foreign runtime's targets would pollute their local
  SSH store.

* Harden the SSH reconnect overlay against stale or unknown target state

- Only present the destructive 'SSH host removed' state on positive
  evidence (a removal tombstone label, or a hydrated non-empty target
  list lacking the id). A client whose SSH state never hydrated has an
  empty labels map for every id and must not offer workspace removal.
- After a failed Connect, resync target metadata so a stale overlay
  converges to the ghost/re-adopted state instead of offering the same
  failing Connect forever (the repeated 'SSH target not found' toast
  loop in STA-1468).

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

* Address CodeRabbit review on #7767

- Re-key workspaceSessionsByHostId partitions stored under a removed SSH
  host id during re-adoption (no writer keys partitions by ssh host today,
  but the schema tolerates it — re-key instead of stranding; live partition
  wins when both keys exist).
- Track SSH target-list hydration explicitly (sshTargetsHydrated) instead
  of inferring it from a non-empty label map, so a legitimately empty
  target list still counts as removal evidence and a never-hydrated client
  still never offers destructive removal.
- Apply the refreshed target list before the best-effort removed-labels
  fetch in the overlay resync, so a labels failure can't discard it.

Neil 6a4e6ce28a perf(ssh): bound the system-ssh port-forward stderr tail (#7647)
The stderr handler in system-ssh-port-forward-provider.ts stays attached
for the forward process's entire lifetime and appends every chunk to an
unbounded string, only ever read to build the exit-error detail. A
chatty/warning-spamming remote sshd over a long-lived `ssh -N -L`
forward could grow it without bound.

Fix: keep only the most-recent 64 KB tail, mirroring
MAX_RELAY_STARTUP_BUFFER_BYTES in ssh-relay-deploy-helpers.ts. The tail
is what the error message surfaces anyway.

Test (red->green): emitting >64 KB of stderr then exiting keeps the
recent tail marker and drops the oldest, detail bounded below the
produced size; without the cap the whole string is retained.

PP 0b4196fc17 fix(ssh): stop deleted ~/.ssh/config hosts from reappearing on sync (#7302)
Deleting a config-sourced SSH target had no lasting effect: the Manage-SSH pane
re-imports ~/.ssh/config on open, and the import was a pure upsert with no record
of deletions, so the just-deleted host was re-inserted verbatim from the config
that still exists on disk.

Persist a `deletedSshConfigAliases` tombstone set:

- Deleting a config-managed target (source 'ssh-config', or an adopted legacy
  import) records its alias; manual targets are never tombstoned.
- The passive on-open sync skips tombstoned aliases, so a deleted host stays
  deleted.
- Re-adding or editing a target reclaims its alias, and the explicit Import
  action (`reAdopt`) clears all tombstones to deliberately re-adopt config.

This also fixes the edit-then-reappear case: editing a config host to `manual`
already reserved its current alias, and reclaim covers alias changes.

Enable three unicorn rules — one correctness, two performance — and fix every
existing violation repo-wide so the rules pass as errors.

prefer-number-properties (76 sites)
- parseInt/parseFloat/NaN -> Number.* : safe aliases (autofixed).
- isNaN -> Number.isNaN (12 sites, hand-converted): global isNaN coerces its
  argument, Number.isNaN does not. Verified every call site already passes a
  number (Number.parseInt results, number-typed fields, Date.getTime()), so the
  conversion is behavior-preserving today and guards against a future non-numeric
  argument silently coercing.

prefer-array-find (26 sites)
- .filter(pred)[0] -> .find(pred); .filter(pred).at(-1) / .pop() -> .findLast(pred).
  Drops the intermediate array and short-circuits.

prefer-array-index-of (5 sites)
- .findIndex(x => x === v) -> .indexOf(v).

Verified: typecheck (node/cli/web) clean, 53 affected suites pass (1679 tests),
oxlint clean repo-wide. mobile/ uses findLast safely (already ships ES2023
.toReversed()); config scripts and e2e helpers run on Node 24.

f215a48064 fix: pr-bug-scan validated finding from #6952 (#7180)
* fix: address pr-bug-scan validated finding from #6952

throwNodeNotFound() now re-raises AbortError when the shared signal is aborted, so a signal-cancelled node probe no longer launders into 'Node.js not found'; sequential fallback runs.

* fix(ssh): make session-limited (MaxSessions=1) relay deploys actually succeed

Review of #7180 verified the parent fallback end-to-end against a real
MaxSessions=1 sshd and found the connect still failed. Four gaps, in order
of discovery:

- isSshSessionLimitError missed stock OpenSSH, which refuses session
  channels over MaxSessions with SSH2_OPEN_CONNECT_FAILED (2) and 'open
  failed' — reason 4 never matched, so the fallback never triggered.
- execCommand settled aborted commands before the channel finished
  closing, so the sequential fallback reissued execs while sshd still
  counted the old session.
- SshConnection.waitForSshCallback rejected aborts mid-channel-open
  immediately, leaking a confirmed-late channel that held the only
  session slot; it now settles after the late channel closes (bounded)
  and drains its streams so ssh2 emits 'close'.
- Session channel opens now retry transient session-limit refusals
  (sshd frees the slot only after processing our close-ack, which the
  next open can beat by microseconds), and the remote orca CLI shim
  install is non-fatal like the managed-hook install — after the relay
  bridge occupies the sole session slot, raw-connection extras must
  degrade instead of failing the connection.

Verified live against Docker sshd (OpenSSH 9.2, MaxSessions=1): fresh
deploy (upload + native deps + launch), reconnect cycles, and a PTY
round-trip all succeed; unrestricted-sshd regression run also passes.

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

* Handle ssh execution aborts immediately during retry backoff or hangs

- Cancel the session-limit retry delay immediately if the operation is
  aborted during backoff.
- Limit the wait time to a 5-second grace period when aborted during a
  channel open that is hung and never invokes its callback, rather than
  waiting for the full connection timeout.

Brandon Barker e6ca3087c5 perf(ssh): resolve node path concurrently with remote install state (#6952)
Run independent SSH relay bootstrap probes concurrently when the connection can safely support overlapping execs. Preserve the old sequential path for system SSH without reusable ControlMaster and for remotes that reject concurrent session channels.
2026-07-02 13:55:36 -07:00
4dbc9f3817 feat(ssh): add ControlMaster multiplexing for system SSH transport (#6922)
* feat(ssh): add ControlMaster multiplexing for system SSH transport

System SSH transport spawns a new OpenSSH process per exec command
(platform detect, relay install check, node resolution, relay launch,
socket probe). Each process pays the full SSH handshake cost — ~9s on
Uber devpods — making a typical relay connect take 54s+ and reliably
exceeding the 15s startup reconnect budget.

Add SSH ControlMaster multiplexing via a per-target socket in
$TMPDIR/orca-ssh-ctl/<hash>.sock. The first command establishes the
master; subsequent commands reuse it at ~100ms per exec instead of ~9s.
ControlPersist=300 keeps the master alive after commands exit so rapid
reconnects (e.g. on tab focus) also benefit. Windows is excluded since
OpenSSH's ControlMaster support there is limited.

* fix(ssh): address ControlMaster key collision and directory permission risks

- Use target.id in the socket key so distinct SSH targets can never
  collide even when configHost/port/user happen to match
- Switch from SHA1 to SHA256 and extend hash slice from 12 to 16 chars
- Stat the control-socket directory after mkdirSync to reject pre-existing
  dirs that are symlinks, foreign-owned, or have group/other write bits
  (mkdirSync mode is ignored on pre-existing dirs)
- Update two tests that used exact spawn-arg arrays; replace with
  ordering assertions (forward flags before --) that stay correct
  regardless of which extra ControlMaster options are injected

* fix(ssh): bind ControlPath identity to route and reject symlinked ctl dir

Fold proxyCommand/jumpHost/identity fields into the ControlPath hash so a
target whose route is edited no longer reuses a still-alive master built on
the old route. Switch the control-socket dir check from statSync to lstatSync
so a planted symlink fails the directory validation outright.

* test(ssh): drop tautological argv re-assertion in spawn checks

The toHaveBeenCalledWith re-passed the args array extracted from the same
mock call, making that argument position always pass. argv content is
already verified by the index-ordering assertions above; use expect.any(Array)
so the spawn check only claims what it actually verifies (binary path, stdio).

NeilandOrca 46646d7ff1 chore(lint): upgrade oxlint to 1.71 + enable 7 new rules (autofixed backlog) (#6841)
* chore(lint): upgrade oxlint to 1.71 and enable 7 new rules

Upgrade oxlint 1.67.0 -> 1.71.0 (1.72 was blocked by the repo's 3-day
minimum-release-age supply-chain guard; nothing here needs it). The
bump is a no-op on the existing config.

Enable 3 error rules (backlog autofixed to zero in this commit) and
4 warn rules (surface signal without gating CI):

error (autofixed, behavior-preserving):
- unicorn/prefer-node-protocol        (~1531 sites: bare builtin -> node:)
- typescript/no-import-type-side-effects (~36: all-inline-type -> import type)
- unicorn/no-array-reverse            (19: copy-then-reverse -> toReversed)

warn (real signal, current fires are test-only/correct):
- unicorn/no-array-fill-with-reference-type  (aliasing footgun guard)
- typescript/no-unsafe-function-type         (bans bare Function type)
- unicorn/prefer-array-flat-map              (map().flat() -> flatMap())
- unicorn/prefer-regexp-test                 (.match() in bool ctx -> .test())

mobile/.oxlintrc.json extends root, so it inherits all 7; the autofix
ran from root and covered mobile/ too.

Verification (all green): oxlint 0 errors (root+mobile+aux configs),
oxfmt clean, typecheck (node+cli+web), vitest 22795 passed / 0 failed,
builds (electron-vite + web + cli) succeed. node: rewrites confirmed to
skip embedded SSH/CLI string payloads (AST-only); all toReversed sites
verified to operate on fresh copies or write-once locals.

* chore(lint): bump mobile oxlint to 1.71 so inherited rules parse

mobile/ is a standalone pnpm project pinning its own oxlint@1.67, which
lacks unicorn/no-array-fill-with-reference-type (needs >=1.70). Since
mobile/.oxlintrc.json extends the root config, mobile CI's 'cd mobile &&
oxlint' failed to parse the new rule. Bump mobile to match root (1.71).

Verified in mobile/: oxlint 0 errors, oxfmt --check clean, tsc --noEmit
pass, vitest 978 passed / 0 failed.
