Revert the terminal IME composition-ownership change (#13282)
* Revert "test(ime): restore coverage the composition-ownership change removed (#13168)"

This reverts commit 25a8c517e1.

* Revert "refactor(terminal): return IME composition ownership to xterm (#13128)"

This reverts commit 17b3dff3c4.

* test(ime): keep the architecture-neutral Korean trace coverage

The recorded IBus/fcitx5 and Windows MS-Korean traces from #13168 assert PTY
byte order, not composition ownership, so they still hold once the terminal
composition layer is restored. The mobile accessory-order test pinned the new
handleLiveInputChange signature and does not.

* fix(terminal): keep the macOS Backslash bypass through the revert

The restored native-text forwarder only claims keys for input sources in its
hardcoded CJK allowlist, so third-party IMEs off that list (Qingg, #10896) still
get a raw backslash. #13128 added this bypass as a partial replacement; keep it
rather than trade the open issue back.

Scoped to the bare backslash key. The rest of shouldBypassXtermForMacNativeText
bypassed all unmodified non-ASCII text, which would race the restored forwarder.

* fix(mobile): move the mirror-step ref write out of render

The restored hook assigned runMirrorStepRef during render, which is not
replay-safe — React can discard render work, so the mutation can leak from UI
that never commits. Its only read is inside the held-commit timer, which fires
long after commit, and the ref has a safe default, so an effect is soon enough.

Surfaced by the changed-lines React Doctor gate: the rule postdates this code,
so restoring the file re-introduced it as a new violation.

* feat(ime): add shared Enter-ownership seams for CJK composition

The confirming Enter of a CJK composition arrives as two keydowns and the
orderings differ by platform: Windows/Linux redispatch the unmarked Enter/13
before keyup, macOS delivers keyup first. A guard reading only isComposing or
keyCode 229 misses the redispatch, so surfaces submitted on a confirm.

Adds useImeEnterGestureOwnership (carry token, next-frame expiry), a shared
ImeEnterGuardedForm for native implicit submission, and the cmdk seam covering
18 CommandInput surfaces at one site.

A chorded Enter arms the carry but is never swallowed — the reverse would eat a
user's deliberate Cmd/Ctrl+Enter. Both failure modes are pinned by
ime-enter-gesture-ownership-contract.test.ts.

* refactor(terminal): consolidate native input listeners and parked-screen owner

Extracts the shared native-input listener installer and renames the parked-screen
detector for what it actually does, replacing per-call-site duplication. The
listener installer keeps a forgetOptionKeyLocationOnBlur flag so per-window
semantics are preserved rather than flattened.

Net deletion; no behaviour change intended.

* test(terminal): pin recorded IME shapes as regression tests

Nine regression tests built from hashed affected-platform captures, each with a
paired ordinary negative and a discriminating mutation verified to take the file
from all-passing to exactly one failure.

Covers the Windows MS-Korean Shift family (#12179, #11878, #12151, #11946,
#12152) and the Korean TUI line-break rows (STA-3237, STA-3222, STA-3129).

STA-3237 pins the empirical 3-Shift / 2-active-composition / 2-newline ratio the
device run established — the third Shift produces nothing because Space has
already committed. That ratio is not derivable from a static capture.

* fix(ime): guard Enter-commit surfaces against CJK confirm

Applies the Enter-ownership guards across the surfaces whose Enter commits
something: publishes, clones, pairs, installs, posts, or persists.

Tiered deliberately rather than uniformly. Irreversible and remote-effect sites
take the carry token, which also blocks the unmarked redispatch. Locally
reversible sites take the oracle check with a one-line comment naming the
residual, because a spurious commit there costs one undo.

Three numeric fields are left unguarded with the reason in-code: Chromium blanks
number inputs at compositionstart, so a confirm-Enter only ever reaches an
empty-draft reset. Measured with a CDP probe rather than assumed — a guard that
cannot fire is noise.

* test(ime): teeth-check the Enter guards on every guarded surface

One suite per guarded surface, each verified by deleting the guard and
confirming the test fails. A green guard test without that check is unverified,
not verified.

Two shapes pass vacuously in happy-dom and are avoided here: native implicit
form submission never fires, and blur() is inert on an unfocused element. Both
made "the commit did not happen" assertions pass with the guard removed, so the
suites assert the guard's contract directly instead.

* fix(mobile): keep iOS Korean commits whole through the live-input path

iOS Korean reports isComposing: false on every event, so it bypasses the
composition guard entirely. The strict owner rejected UIKit's transformed
post-change field and sent only the leading jamo — the reported symptom.

Prefers the authoritative same-event field text over the predicted text when the
supplied operation cannot produce it. Generic: no Korean special-case, no locale
classifier, no normalization. Adds the RN-target-keyed submit carry alongside it.

* test(e2e): make IME capture harnesses fail loudly instead of silently

Four instruments recorded silence as success, so a void run scored as a clean
one:

- readTerminalImeBoundaryTrace returned an empty trace when the probe never
  installed, making every "nothing leaked" negative pass vacuously
- summarizeLatencies([]) returned a perfect zero distribution that passed all
  three latency thresholds
- the macOS Vietnamese spec pinned an input-source ID that does not exist, and
  failed as though the operator had chosen the wrong source
- the expectedLineCount=1 prefix property was undocumented and one edit from
  silently downgrading a PTY assertion

Input sources now resolve by enumeration and name the near-matches on failure.

* test(terminal): cover Cangjie cancellation and fix a cross-namespace assertion

Adds #11951's recorded Cangjie cancel shape to the existing cancellation suite,
which covered Pinyin and Sogou but not Cangjie. One keystroke then Backspace
arriving as deleteContentBackward with data: null, so the stale preedit is the
only thing a fallback could replay.

Verified against the historical pre-6cd944c62b3 bundle: the positive fails with
['尸'] where [] is expected, while the ordinary negative stays green.

Also fixes the Vietnamese spec, which asserted a TIS-space input-source ID
against getKeyboardInputSourceId(). Those two Orca APIs report the same source
in different namespaces — TIS nests it under VietnameseIM, the app API does not.
The resolver stays as an installation precondition; the assertion matches the
leaf.

* test(e2e): add a real-IME macOS arm for the Korean chord commit

The existing korean-ime-terminal-shift-enter-commit spec synthesizes composition
over CDP: Input.imeSetComposition sets the preedit directly and Input.insertText
performs the commit. Asserting the IME produced events you injected yourself is
circular, so that spec cannot certify real-IME behaviour.

This arm selects 2-Set Korean via TIS, reads it back live, and injects through
System Events key codes, so the OS owns the preedit, the commit instant, and
isComposing. PTY byte expectations are preserved verbatim.

Covers 2 of the original 4 cases by design. The other two are the Windows/Linux
redispatch-before-keyup ordering, which macOS cannot produce and which cannot be
selected -- the OS decides it. Reintroducing synthesis to "restore coverage"
would reintroduce the circularity.

* test(e2e): assert the macOS chord arm at the PTY boundary, not the renderer

The byte expectations were transcribed from korean-ime-terminal-shift-enter-commit
:364/:383, which assert against onData -- a renderer boundary where the terminator
is CR. This spec reads the PTY child, where the tty has already converted CR to LF.

Names both forms per row rather than swapping the constant, so the conversion reads
as evidence that the capture reached past the renderer, as #11936 and #11951 record.
Ctrl+Enter's CSI-u sequence is unaffected and is identical at both boundaries.

* test(e2e): measure composer-to-onData latency and stop dropping IME keystrokes

Two defects in the echo latency probe.

It hooked onWriteParsed and onRender but never onData, so it measured
key->parse->render echo rather than the composer-vs-onData delta the latency rows
need. Adds a third hook feeding its own sample set.

And `event.key.length !== 1` silently dropped IME keystrokes: Pinyin and Cangjie
keydowns arrive as key:'Process' (length 7). Replayed over the captured corpus,
the old filter accepted 580 of 4137 Chinese IME keydowns -- it was discarding 80%
of them. The new filter matches the shape the owner itself branches on.

Attribution charges each onData to the latest keydown rather than a FIFO head,
because composing jamo emit no onData at all and a queue would credit a whole
composition to its first keystroke. The consumer now asserts sample count before
any percentile, so a zero-sample run cannot render as a flawless distribution.

* test(terminal): pin the WSL shifted-jamo newline shape for #11919

In Korean 2-set, Shift types ordinary letters -- the double consonants and the
compound vowels. Each such keystroke reaches Chromium as key='Process',
keyCode=229, shiftKey=true.

The v1.4.163 classifier matched exactly that pattern with no code guard, so it
called those keystrokes Enter, rewrote them to a synthetic Shift+Enter, and
injected a newline into the middle of the word -- with no Enter key pressed.
That is why the reporters said "no modifier key pressed": they had not chorded
Shift+Enter, but they had pressed Shift, to type the double consonant.

Asserts the row's own recorded capture: 40 immediate keydowns, exactly 3 of them
Shift-carrying inside a single syllable, and an onData stream with one newline
per Enter press and none mid-word. Two ordinary negatives keep it from being a
blanket mute -- the same session's non-IME keydowns still reach shortcut policy,
and an ordinary Shift+Enter still resolves through the real policy.

* test(terminal): pin the composition commit lag that made Korean type one behind

macOS Korean 2-Set commits syllable N only when the first jamo of N+1 arrives, so
compositionend and compositionstart land in the same task. A composition-start
handler cancelled the pending finalizer that was the only path to triggerDataEvent
and ended the session without emitting bytes, so every committed syllable reached
onData exactly one syllable late and the backlog cleared only at a Space or Enter.

Types continuously with no Enter and no Space -- either would flush the backlog and
hide it -- and samples onData at every syllable boundary. Paired with a
length-matched ASCII arm that stays green throughout, so the positive is a fact
about composition rather than about timing in general.

Bisected to a single call site across five builds: pristine, 1.4.155 and 1.4.162
pass, 1.4.163 fails, removing the one call repairs it, restoring it fails
identically. That window is exactly the reporter's "started immediately after
updating".

* test(mobile): cover the send-queue abort that silently drops queued keystrokes

One failed send in use-terminal-live-input-commit aborts every keystroke
queued behind it, with the error swallowed by .catch(() => false). The
existing test resolves(true) on every send, so the failure branch was
uncovered.

Four arms: the abort itself, an ordinary negative on the healthy path, a
throwing sender, and a liveness control proving the queue recovers once
the chain settles. Deleting the abort takes 4 passed to 3 failed, with the
ordinary negative correctly surviving.

Scope is stated in the docblock: this is a transport send-queue abort,
reachable only via a real disconnect or RPC error. REQUEST_TIMEOUT_MS is
30s, so latency alone cannot reach the branch — consistent with #7094's
symptom class, not proven to be its cause.

* test(terminal): pin that daemon snapshot/restore cannot disturb a composition

Two independent reporters attributed broken Korean composition to the
always-on PTY daemon repainting terminal state over the preedit. The
attribution is wrong on ancestry — the daemon shipped three months before
the version both call good — but the boundary was never actually tested.

Runs the real applyMainBufferSnapshot choreography against a live
composition, including the full 2J/3J/H wipe plus the resize and
alt-screen branches. textarea.value, selectionStart/End,
compositionView.textContent and .active all survive byte-identical, and
interleaving a restore between every jamo of 문제 still commits 문제 at
onData. Also pins that the uncommitted preedit is absent from the captured
snapshot: it lives in the textarea, never the buffer, so a restore has
nothing stale to echo back.

Injecting one textarea.value = '' into the restore fails exactly the three
restore-boundary tests.

* test(terminal): pin that Cmd tears down a composition where Ctrl and Shift do not

xterm's composition keydown exempts only keyCode 16/17/18 (Shift/Ctrl/Alt)
plus 20/229. macOS Meta — 91/93/224 — is absent, so a Cmd press mid-composition
takes _finalizeComposition(false): the overlay goes dark and never recovers,
because compositionstart is not re-fired. The user composes the rest of the
word blind. Linux and Windows users press Ctrl and are exempt.

xterm already has a Meta-aware modifier predicate in wasModifierKeyOnlyEvent,
so this is an internal inconsistency rather than a deliberate choice.

Owns no reported row and is version-neutral: 5/5 on both 1.4.162 and 1.4.163.
The branch is unexercised in all 328 recorded traces, so this is a hazard pin,
not a regression guard. Only the teardown is asserted; the likely duplicated
commit needs a compositionend the IME kept alive across the Cmd, which no
capture contains.

Deleting the exemption fails exactly the three paired negatives; adding Meta
to it fails exactly the two Cmd arms.

* test(native-chat): characterize preedit loss when a question card replaces the composer

An AskUserQuestion card fully replaces the composer by design, but the
in-flight composition goes with it: the composer unmounts before
compositionend reaches it, so the preedit is never committed to the draft.
The committed text survives only because the draft is cached and restored
via defaultValue. Node identity changes, value 'abc' is preserved, the 가
is gone.

Drives the real NativeChatView -> SessionGate -> InteractiveCard ->
questionActive swap -> Composer -> ComposerField, flipped by writing the
same store field an AskUserQuestion hook event writes. Flipping
questionActive to false fails exactly this test and nothing else across
639 native-chat tests, so the path was entirely unguarded.

CHARACTERIZATION TEST: it asserts the loss. Fixing the defect — committing
the preedit before the swap, or keeping the composer mounted — will make
this file fail. Update the expectations to the new contract rather than
working around them.

Owns no reported row. #12118/STA-3219 flicker is keyed to token counters,
which provably do not remount, and a question card arrives once per
question.

* test(terminal): pin the duplicated commit when Meta interrupts a composition

_finalizeComposition(false) sends textarea.value.substring(start, end) but
cannot clear the IME-owned textarea, so a later compositionend re-sends the
same range. Meta reaches that path because CompositionHelper exempts only
Shift/Ctrl/Alt; xterm's own wasModifierKeyOnlyEvent covers Meta four ways,
so the omission is an internal inconsistency rather than a choice.

Companion to the modifier-exemption guard, which deliberately pins only the
overlay teardown. This pins the data consequence.

HAZARD PIN: owns no reported row. The trigger is unverified on hardware —
no capture in the corpus contains a Meta-during-composition gesture, and
whether macOS keeps the composition alive across it is unmeasured. The
duplication follows from the code given that sequence; whether users reach
the sequence is the open half.

An earlier premise that Space (keyCode 32) reaches this path was refuted by
a corpus scan: 0 of 731 evidence files carry a keyCode-32 Space while
composing, against 171 at 229, and 229 returns early.

* test(terminal): characterize the syllable lost when the textarea blurs mid-composition

CoreBrowserTerminal._handleTextAreaBlur clears the helper textarea
unconditionally — "Text can safely be removed on blur" — while
CompositionHelper._finalizeComposition reads the committed text back out of
that same value from a deferred timeout. By the time it runs the value is
empty, the substring is '', and triggerDataEvent never sees the syllable.
xterm checks composition state in _syncTextArea and omits the same check
here.

Six cases. Blurring mid-composition loses the syllable in every ordering,
including compositionend-before-blur, which is Chromium's real order — so
it is not an ordering artifact. A bare textarea.blur() with no Orca code
loses it too, which places the owner upstream: Orca's unguarded release on
outside pointerdown is one trigger, not the cause. Committing 한 then
blurring mid-가 yields ['한'] where ['한','가'] is correct: one syllable
gone, surrounding text intact.

Teeth checked by inverting — adding an Orca-side composition guard flips
exactly the three cases that route through the release path and leaves the
bare-blur and no-blur cases green, which is the scope split: a fix in
regular-terminal-focus-ownership alone would not close this.

HAZARD PIN, but unlike the others this one has a real production injector —
clicking outside the terminal mid-composition. Owns no reported row. The
shape matches #9738's report; the injector does not, and a shape match with
a mismatched injector is not an owner.

* test(terminal): say which arm the STA-3237 fixture came from

The recorded keydowns are wave 4's A-shift-unmarked-only — the arm that
emits no PTY bytes. Nothing in the file said so, so two readers concluded
the row's events fail the owner's predicate and that STA-3237 and STA-3222
were different defects. They share an owner; the arm that fires is
Process/229+Shift, absent from this bubble-phase trace because the owner
claims it in the capture phase.

Also corrects "code-blind": the v1.4.163 policy emits \x1b\r only for a
shift-only key:'Enter', and a jamo keydown reaches that branch solely via
the isTerminalImeProcessEnter rewrite. The mock is deliberately wider so
the ownership guard stays under test if that rewrite moves.

Comments only — no assertion, fixture value, or mock behaviour changed.

* test(e2e): track the input-source selector the macOS specs shell out to

Five tracked macOS IME specs ran `swift .tmp/select-input-source.swift`, a
file that is gitignored and existed only on one machine. Anyone else
checking out the repo — or the same machine after .tmp is cleaned — could
not run them, and they are the capture drivers for the macOS rows that are
blocked waiting for exactly those runs.

Moves it to tests/e2e/ beside its callers. The chord spec now resolves it
from __dirname rather than reaching two levels up into .tmp.

* test(terminal): pin the CJK repaint decision against the reporter's own output

#12164 comment 1 and #5921 report agent output with double-width glyphs
rendering duplicated character-by-character while ASCII in the same line
stays clean. No IME, no composition, no keystroke — the user never types
the CJK.

Segmenting all three verbatim samples into maximal same-risk-class runs
gives 33 runs and zero violations of "this run is corrupted iff the
production detector flags it": 17 wide runs all corrupted, 16 narrow runs
all byte-identical. The paired negative is co-located in the same line
rather than in a separate run — the reporter supplied it without knowing.

Doubling is asserted as present, not uniform: 자바스크립트 and 시스템 each
leave a jamo undoubled, which is a repaint-region boundary artifact rather
than a per-character transform.

The discriminating arm is in the test rather than a source mutation:
be3f30e2f8 (#6890) elects a repaint for all 17 corrupted runs when the
agent types nothing, and reverting its disjunct elects none. Both
predicates agree once the user has recently typed, which is the pre-#6890
condition.

Samples inlined with per-sample SHA-256 because .tmp is gitignored and
cannot back a landed test.

* test(terminal): pin macOS period substitution landing after the composition

#11504's reporter published a DOM trace showing insertText ". " arriving
149ms after compositionend, when two spaces are typed with a CJK input
source and NSAutomaticPeriodSubstitutionEnabled is on. This replays that
trace against a real Terminal and asserts what reaches onData — bytes to
the PTY, not anything visual.

The owner is stock upstream CoreBrowserTerminal._inputEvent, not an Orca
module, confirmed at the resolved install and in the shipped bundle Vite
loads rather than in the TypeScript source.

Three mutations against that install, predictions written before the runs,
each failing exactly the arms predicted: dropping the composed/keyDownSeen
guard fails two, dropping Orca's intercept fails the one arm where the
payload arrives before the send window drains, and flipping || to && —
the candidate-fix shape — fails the arm that pins the defect itself.

CHARACTERIZATION: arm 1 asserts the broken behaviour and will fail the
moment #11504 is fixed. Update it to the new contract rather than working
around it.

composed is absent from every recorded bundle, so composed: true is the
spec-required value rather than a captured one; the test asserts it before
dispatching so a harness that dropped the field fails loudly.

* test(terminal): replay the recorded Windows Shift sessions through the IME guard

STA-3179 reports a Shift release sending Enter; #12171 reports delayed
Hangul plus doubled newlines. Both replay their own recorded Windows
MS-Korean keydowns through resolveTerminalKeyboardShortcutAction with the
shortcut policy mocked, so the assertions are about which events reach the
policy and what reaches terminal input.

STA-3179's held-Shift gesture yields exactly one newline, from the unmarked
Enter alone; its release arms nothing for the next composition, asserted
after a precondition check that the release really is keyups with shiftKey
already dropped; and an ordinary Shift press-and-release still routes every
keydown, which is the paired non-IME negative.

Teeth, verified by mutation: bypassing the isImeOwnedKeyboardEvent guard in
keyboard-handlers takes STA-3179 from 3 passed to 2 failed / 1 passed — the
survivor being the ordinary-session negative, which is correct, since a
non-IME session should not depend on that guard — and #12171 from 2 passed
to 2 failed. Source restored byte-identical.

Recorded shapes are inlined and the bundles cited in comments; nothing is
imported from .tmp, which is gitignored.

* test(native-chat): correct 61977d45177 — the preedit survives the question card

61977d45177 claimed a composed syllable vanishes silently when an
AskUserQuestion card replaces the composer, and characterized that loss.
The claim was false. Its premise was an artifact of the harness: the test
simulated a preedit with a silent textarea.value assignment and no input
event, which no IME does.

Real composition fires input with insertCompositionText on every keystroke
— the shape this repo already records in its own observed-event capture —
and React's change handler returns on input/change with no composition
gate, so onChange runs for each frame. The draft cache is written
synchronously inside the updater, so the preedit is already committed
before the card can arrive. Driven that way, it survives.

Renamed to match the contract that actually holds, and extended: Hangul
jamo-per-frame, Japanese kana accumulation followed by per-segment
conversion asserting the candidate the user was looking at survives, and a
pin on the mechanism itself — the draft cache holds the preedit while the
card is up.

Teeth: there is no fix to revert, so the mutation is the plausible wrong
one — gating onChange on isComposing(). That takes 4 passed to 3 failed,
with the English negative correctly surviving, since it has no composition
to gate.

Two consequences remain, recorded rather than fixed: the OS aborts the
composition when the field disappears, so a lone jamo returns as a
compatibility jamo the user cannot compose onto, and the remounted
composer is unfocused because the card owned focus.

* docs(native-chat): name the corrected commit and the degraded-jamo consequence

Records in the file itself that 61977d45177 is pushed and wrong, quoting
the two claims that are false, so a reader who finds it in git log reaches
the correction from the file that replaced it.

Also states the residual as a consequence rather than a curiosity: a lone
leading jamo returns as a standalone compatibility jamo (U+3131), which is
not a composable state — the user cannot resume the syllable, only delete
and retype. Preserved, but degraded into something unusable. That is the
note to find if a reporter ever describes exactly that.

The invariant these tests pin is not "the composer commits on unmount" but
"composition input events must reach React" — which is what a future IME
change would break, and is not visible from the swap site at all.

* test(terminal): replay the recorded macOS Telex commit boundaries

#6905 reports Vietnamese composed characters breaking in the terminal.
Replays the retained macOS built-in Simple Telex capture — recorded
selection and value set before each dispatch, since that is what the
commit range reads — and asserts what reaches onData: the first commit
alone, then through the real Enter, then the ASCII tail of the same run.
A code-point count would catch NFD normalisation.

ENGINE CAVEAT, stated first in the docblock: this is macOS built-in Simple
Telex, Telex only. The reporter's three named engines cannot run on the
platform they declared, and which macOS Vietnamese engine they used is
unconfirmed. This file certifies no engine, and does not imply VNI.

The owner is upstream's — CompositionHelper._finalizeComposition's
waitForPropagation branch — so the arms are copies under .tmp aliased by a
scratch config, with node_modules verified unchanged by shasum after every
run. Collapsing the range end onto its start fails all three; collapsing
the start to zero re-emits the first word into the second commit, which is
the reporter's "duplicated" direction. Different failure sets, so the
mutants are distinguishable rather than merely detectable, and the ASCII
assertion passes under both.

Falsifiability here is by mutation, not by a defective build: #6905 does
not reproduce at HEAD, so this has never been watched going red on a real
reproduction.

* docs(terminal): lead the #6905 test with its engine caveat

Comment-only. Moves the caveat above the source line so a reader meets what
the file does NOT establish before what it does — the capture is macOS
built-in Simple Telex, the reporter's named engines cannot run on the
platform they declared, and which engine they used is what gates this row.

* docs(terminal): record that the swallow eats a keystroke after Japanese conversion

This pin framed the swallowed insertText around Cmd interrupting a
composition. A differential through Japanese multi-segment conversion shows
it is broader: type a segment, convert, then press `a`, and the `a` is
lost. No modifier, no exotic gesture. Korean surfaced it first only because
2-Set composes on nearly every keystroke.

Also records why it cannot simply be fixed. The suppression de-duplicates
IMEs that deliver their commit a task after compositionend, which a sibling
test pins; this swallow is that dedup's false positive, and the two events
differ only in payload, so no flag-timing change separates them. Both a
smaller redesign and a content-aware variant were built and measured — the
first duplicates on IBus, the second costs a reported row's test and is
blocked while the patch cannot be regenerated.

The Japanese arrays behind this are authored, not observed: no Japanese DOM
composition trace exists in the corpus.

* docs(terminal): a Japanese capture does exist — correcting dbeecb11bee

That commit said no Japanese DOM composition trace exists in the corpus.
False. One does, filed under the Linux bundles rather than the bundle named
for Japanese: 30 DOM events, two にほんご->日本語 conversions, with full
selection state per event. It is retained byte-identically in three further
bundles — one capture copied four times, not four observations, checked by
hash rather than by counting files.

The claim came from checking the bundle named for Japanese, finding nothing,
and generalising to the corpus without querying the rest of it.

Replaying it emits 日本語日本語 under both sequencing extremes on all four
arms, matching its own recorded onData. So "repeated conversion is
undisturbed" is now captured rather than authored. It carries no
post-compositionend insertText, so it cannot speak to the swallow: the
a-after-conversion figure stays authored and unobserved.

Also rewords the paragraph opener. It claimed to broaden a Cmd framing, but
hazard 2 was never Cmd-framed — the lines above already say Cmd does not
reach it. The real gap was that hazard 2 named no trigger at all, which
reads as exotic when it is ordinary.

* build(xterm): land the patch regeneration harness

The five dependency patches under config/patches/ shipped with no tracked
way to regenerate any of them. The xterm one is the hard case: it is derived
from an upstream build, so no fix could be made without rebuilding, and the
tooling to rebuild lived only in one machine's scratch directory. That
blocked a measured fix for a live keystroke-loss bug, and the EditContext
reduction an OSS survey identified as the only real one available.

Adds the regenerator, the upstream pin, the hand-written source patch the
bundle hunks derive from, tests, docs, and a PR job that verifies the
shipped patches still match the pinned build. The job caches the shallow
clone keyed on the manifest, so a cold run is minutes and a warm one under
one. Round-trip verified: regenerating from a clean checkout reproduces the
shipped patch byte-for-byte.

Marks the emitted patch -diff -text. pnpm hashes it byte-for-byte, so a
CRLF checkout would break install on Windows, and its minified bundle lines
make a diff nobody can read — review the source patch instead.

Also rejects unknown flags. --check was the fallback for any unrecognised
argument, so a typo, or --help, silently triggered a full upstream build
instead of what the caller asked for.

* fix(xterm): stop swallowing a keystroke typed after an IME commit

Type a Japanese segment, convert it, then press a key one macrotask later
and that key was lost. No modifier, nothing exotic — every user who keeps
typing straight after converting. Korean surfaced it first only because
2-Set composes on nearly every keystroke.

handleCompositionInput discarded the payload unconditionally in the window
after the deferred send: _isSendingComposition stays true for one macrotask
after the timer cleared _pendingCompositionStart, and the branch substituted
'' for whatever arrived. The suppression is not itself wrong — it
de-duplicates IMEs that deliver their commit an event-loop turn late, which
terminal-stock-composition.test.ts pins. It just could not tell a duplicate
from new input, because the two events are identical apart from payload.

Now it compares against _sentComposition, the text the deferred send
actually emitted, and discards only a match. A flag-timing redesign was
measured first and rejected: it fixed this and duplicated on IBus, because
no timing change can separate events that differ only in content.

Edited in config/patches/xterm-src/ and regenerated through the harness, so
the emitted patch and the lockfile hash are derived, not hand-written.

The commit-overlap pin's swallow arm now asserts the repaired contract —
the value its own comment already named as correct and as what stock
beta.287 emits. #11504's arm at :184 flips too; it never covered that
report, as its own prior note recorded, and the reporter's +149ms arm is
untouched and still asserting the defect. Provenance hashes in three test
docblocks are updated, since regenerating changes the patch hash and with it
the resolved install directory.

* docs(terminal): re-measure the #6905 mutation citations against the new bundle

Regenerating the patch moved the resolved install, so this docblock's
patch_hash, line count, two line numbers and three mutation outcomes all
described a bundle that no longer exists. The deferred branch is one the
fix writes into, so the outcomes could not be re-pointed on reasoning.

Line numbers read off both files by diffing anchors rather than derived by
arithmetic: 201 to 205, 159 to 163. Outcomes re-run through the retained
rig, which re-resolves through the module loader and re-derives each arm
from a unique minified anchor: pristine 3 passed, m1 3 failed, m2 2 failed,
m3 3 passed — identical to the old bundle. Guard controls in both
directions exit 1, so the counts are falsifiable.

Comment-only; the assertions and expectations are unchanged.

* fix(xterm): size the preedit overlay to the cells its text will occupy

updateCompositionElements computed the overlay's left edge from the grid
but never its width, so the preedit rendered at the font's natural advance
while the committed text takes two cells per wide glyph. Measured in
Chromium 150: 가나다라 drew 48.45px as a preedit and 69.20px once committed
— the same characters, same font, 30% narrower, and drifting further with
each syllable. Every macOS mono font carrying Hangul measured 0.49–0.72 of
two cells; never 1.0.

Deriving the width from wcwidth and the cell measure moves Korean, Japanese
and Chinese to 1.000 and leaves ASCII at 1.000, which it already was:

  한        12.125 -> 17.297   (17.30 expected)
  가나다라   48.453 -> 69.188   (69.20)
  안녕하세요 60.563 -> 86.500   (86.50)
  日本語     42.000 -> 51.906   (51.90)
  abcdefgh  69.234 -> 69.203   (69.20, unchanged)

Edited in config/patches/xterm-src/ and regenerated through the harness, so
the emitted patch and lockfile hash are derived rather than hand-written.

The unit test asserts the arithmetic, which is what CI can run. The pixel
consequence was measured on macOS with SF Mono in an Electron harness, not
on the Windows font stack STA-3232 reports from — so this demonstrates the
mechanism and does not stand as that row's platform evidence.

* test(e2e): pin the macOS Korean preedit as visible only while composing

#11914 reports the composing text invisible until Space. Its c3 was recorded
as unobtainable, and the reason on file was wrong: the boundary IS
assertable, but not in happy-dom, which reports display:block in BOTH the
active and inactive states and zeros for every rect. A test there passes
with the defect present.

Captured on real hardware instead: hidden and 0x0 before, .active with
display:block, a 15.84x16 rect and checkVisibility() true while composing
그, hidden again after. 39 DOM events, 2 composition starts, onData
["한","그","\r"].

Two mechanism findings are carried in the setup because both are invisible
in the result and fatal if removed. The input source must be selected AFTER
the app takes focus — focusing resets it to ABC. And the IME must be warmed
until an observed keyCode 229; typed cold it emits raw QWERTY (g k s r m)
with no composition at all, which is indistinguishable from an IME that is
not installed. Two runs were voided on exactly that signature before the
warm-up was found.

The has229 and compositionStarts assertions exist to make such a run fail
loudly rather than pass as a clean negative.

Gated on darwin plus ORCA_E2E_NATIVE_MACOS_KOREAN, like its siblings. The
final spec form has not itself been executed — the machine became
unavailable — so it carries the probe's measured values as literals rather
than a run of its own.

* docs(e2e): correct 19a8d133db7 — the Korean preedit spec has been executed

That commit said the landed form had never run and carried the probe's
values as literals. It has now run on real hardware: 1 passed, 9.1s, rc=0,
with the capture and log sealed under a verified hash manifest.

The teeth check was also run rather than reasoned about, and it changes
which assertion matters. Forcing the active overlay to max-width:0 with
overflow:hidden — invisible on screen — leaves the active class, the
textContent, display:block AND checkVisibility() all passing. Only
during.rect.width fails. checkVisibility() is not sufficient against this
defect; the bounding rect is the single load-bearing assertion, which the
docblock already said and this run confirms.

An earlier teeth attempt injected the CSS mid-run and tripped the
hasActiveClass poll instead, failing at the wrong assertion. It is
inconclusive and excluded from the seal rather than counted.

* test(terminal): add #12171's ordinary-English arm from a real Windows capture

c4 was recorded as unmet and the ledger sourced its control to
evidence/windows-current/, which holds 12 captures and not one English one.
The arm here comes from windows-9803-final instead — same probe, same host
geometry, same injector, en-US with no IME, replayed keydown for keydown.

Two limits are stated in the file rather than left for a reader to find. It
is a different bundle and a different run about 3.6 hours later, so it is
not a same-run arm. And it is #9803's range-active MUTANT arm: ordinary
English stays byte-exact even with that saved-range mutation live, which is
why it reads as a negative rather than as a baseline.

Bundle cited by directory with its file SHA-256; MANIFEST.sha256 verifies
21/21, rc=0. Nothing imported from .tmp.

* docs(terminal): correct #12164's grounds — the cited comments say no such thing

The rejection of #12164 from this file's family was recorded as resting on its
comment 1 (output doubling) and comment 2 (filed against 1.4.163). Checked
against the API: the issue has exactly two comments, neither of which says
that, and the string 1.4.163 appears nowhere in the thread.

The conclusion survives on better grounds. The issue BODY's repro is "Run any
CLI agent (Codex, AGY, Claude, etc.) that outputs Korean text into the Orca
terminal" — untyped output, no keystrokes, no composition — so excluding
CompositionHelper is right, and the input-path hunt was looking in the wrong
place. The body is also LLM-authored (it still contains a literal
"## 5. GitHub Submission Draft (Ready to Post)") and its Root Cause section
blames a CJK IME preedit buffer its own repro never engages, so it should not
be read as observation.

Comment-only; suite unchanged at 5/5.

* test(native-chat): make composition frames carry isComposing, not just inputType

This suite's comment claimed "Gating onChange on `isComposing` breaks here."
It did not. composeFrame() fired `input` with `inputType` but never set
`isComposing`, so a gate on `isComposing` passed all four tests untouched —
the suite asserted a discriminator it did not exercise.

Composition frames now carry both, so neither gate is exempt. Verified by
pointing the mutant at it: with an `isComposing` gate on the composer's
onChange, this suite now fails 3 of 4 (it passed 4 of 4 before), and the
ordinary-English arm correctly survives, since a composition gate should not
touch it. Production code is unchanged and stays gate-free; the mutation was
applied, measured, and reverted.

Found while excluding NativeChatView's question-card remount as the owner of
#12118 / STA-3219: the remount is real, but the preedit survives it precisely
because this write path has no composition gate.

* fix(mobile): ship the patched xterm build, matching desktop

mobile pinned @xterm/xterm 6.1.0-beta.285 while the patch is keyed to
6.1.0-beta.287, so mobile shipped stock xterm and neither IME defect fix
reached it: the swallowed keystroke after an IME commit (9506039de72) and
the preedit sized to the font rather than the grid (e04e0c88da5).

Bumps the three xterm packages to the desktop versions and adds the patch
to mobile's own pnpm.patchedDependencies. No copy of the patch: pnpm
accepts the parent-relative path and records it in the lockfile against
hash 8d63166272e9040a…, byte-identical to what desktop resolves, so the
two stay in step by construction rather than by a drift check.

The workspace separation is untouched — root pnpm-workspace.yaml still
declares `packages: []` and mobile keeps its own lockfile, which is what
keeps the root's patches from failing as ERR_PNPM_UNUSED_PATCH.

Verified in the generated webview bundle rather than at the install:
alignPreeditToGrid 0->2, sentComposition 0->3, pendingInput 0->11, and the
stock-only _handleAnyTextareaChanges 2->0 and dataAlreadySent 4->0. pnpm
applies patches during linking before postinstall regenerates the bundle,
confirmed by a revert/reinstall/re-apply cycle in both directions.

Mobile suite 2971 passed, 3 skipped — identical before and after. Bundle
+1,514 B (+0.24%). Lockfile churn is xterm-only; --frozen-lockfile passes.

mobile/src/ime/ime-submit-carry.ts is NOT made redundant and is untouched:
it handles iOS firing onSubmitEditing on a React Native native TextInput
after unmarking a composition, which is outside the WebView entirely.

Known divergence left alone: desktop also patches @xterm/addon-webgl and
mobile now runs that version unpatched. That patch is glyph/texture-atlas
rendering with nothing IME-related, so it affects neither fix.

* test(terminal): pin the preedit overlay against already-committed cells

STA-3132 (arm A), STA-3170 and STA-3232 report a Korean preedit painted on
top of text already on screen. Builds v1.4.163-v1.4.166 cancel the pending
finalizer in compositionstart, so a committed syllable reaches onData one
syllable late and buffer.x is stale — the overlay lands on the cell the
flushed syllable is about to occupy.

Replays a recorded hardware trace rather than an authored one: the ordered
DOM event stream captured on Windows + MS Korean (wave5-r2 evidence, 64
events), echoing onData back as PTY output.

The load-bearing assertion is deliberately not the obvious one. Comparing
overlay style.left against cursorX is tautological — left is computed from
buffer.x. This counts committed syllables from the compositionend events
the IME fired, so the two sides are independently derived.

Discriminated by a historical re-add across seven real bundles, since the
owner is deletion-shaped: pristine beta287, v1.4.155 and v1.4.162 pass;
v1.4.163 fails; v1.4.163 with that single call removed passes; the byte
identical baseline restored fails again; head passes. Every failing arm
fails only this case — the ordinary negative stays green in all seven.

The negative asserts its own category rather than claiming it: zero
composition events, zero isComposing, zero keyCode 229, exactly 16 events,
paired against the Korean arm's 4 starts / 3 ends / 11 updates / 64 events.

Scope: cell indices, not pixels. happy-dom has no layout, so the recorded
8x16 cell metrics are supplied to the render service. This makes no claim
about pixels visually overlapping; that is affected-OS confirmation and
stays open. Covers the overlap arm only — STA-3132's auto-line-break arm
and STA-3232's half-line-capacity and a11y arms are untouched.

* test(e2e): matrix macOS period substitution against the OS preference

#11504 reports macOS inserting ". " after a Hangul Space commit. This
sweeps six arms across both states of NSAutomaticPeriodSubstitutionEnabled,
reading the preference live per run rather than asserting a literal.

Two results worth having on record.

The reporter's stated trigger did not reproduce. Their words are "There is
no second press at all. One space is enough", but korean-single-space emits
zero insertText with the preference on or off. So does word-space-word-space.

Their timing does reproduce, with different content. korean-double-space and
korean-longer-word-double-space emit a delayed insertText at +122.5-122.7ms
after compositionend — squarely the reported +149ms — but the payload is a
space, never ". ". Consistent with the double-space rule seeing two slots
under ABC and only one under Korean, where the IME commit consumes the first.

The substitution itself is real and preference-bound: latin-double-space
gives "ab . " with the preference on and "ab  " with it off, on one build
with the preference as the sole variable, reproduced across two runs.

That also refutes a claim in PR #11506, which states the substitution "is
enforced outside the renderer and never reproduces in dev builds, so changes
here must be verified against a packaged app". It reproduced in the dev build
twice and did not reproduce on the signed packaged app. That claim should not
be used as a verification gate.

Gated @headful behind ORCA_E2E_NATIVE_MACOS_PERIOD, same shape as the Korean
preedit spec, so it does not run in ordinary CI. Evidence is onData and DOM
only — the PTY-child reader aborted and no packaged-app arm was stable.

* test(terminal): actually enforce the recorded jamo progression

The preedit assertion compared sample.overlayText against sample.overlayText
— the same expression on both sides. A lane proved it by mutation: corrupting
seven of the eight recorded preedit values left the suite fully green. So the
docblock's ㄱ→가→간→나→낟→다→달→라, which the matrix also cites as this row's
recorded shape, was cited and unenforced.

The first attempt at a fix was insufficient and is worth recording. Threading
stroke.preedit through to the expectation still passed on a corrupted fixture,
because that value both drives the rig and was the expectation — corrupting it
moved both sides together. Same tautology, one level down.

The expectation is now an independent literal. Verified by mutation rather
than by reading: corrupting two recorded values fails one arm; restoring them
passes 3/3.

overlayCell was never affected — it is compared against a count derived from
the compositionend events, not from the buffer, and remains the load-bearing
assertion for the overlap.

* fix(e2e): select the selectable input source, not the first match

TISCreateInputSourceList can return several entries for one input source
id. A third-party IME publishes a non-selectable parent alongside the
selectable mode, and taking sources.first can return the parent — after
which TISSelectInputSource fails with paramErr (-50) while the caller
reports success from the enable step.

Found with Qingg (com.aodaren.inputmethod.Qingg), which exposes exactly
that pair under one id. Its mode id equals the bundle id, so filtering by
name would not have helped; selectability is the discriminator.

Now filters on kTISPropertyInputSourceIsSelectCapable and falls back to
the old behaviour when nothing advertises it, so single-entry sources are
unaffected. Also enables every entry for the id rather than only the one
being selected: selecting a mode whose parent is still disabled fails the
same way.

Compile-checked, and selecting com.apple.keylayout.ABC still exits 0.

Unrelated to the enable path: on macOS 26.5.2 third-party IMEs are gated
behind a consent sheet in System Settings. TISEnableInputSource returns
noErr immediately regardless, and the enable only lands if that sheet is
answered while the requesting process is still alive.

* test(terminal): discriminate #12171 against the real shortcut policy

The prior candidate mutation for this row was correctly refused: its suite
mocked shortcut policy so Process/229 became actionable, while the real
resolveTerminalShortcutAction has no Process branch — so the kill measured
the mock. This does not mock it.

Replays a capture of this row's own gesture (d, l, Shift+T, e, k, Space,
Enter under MS Korean, committing 있다) taken on Orca 1.4.164, through the
real useTerminalKeyboardShortcuts hook, capturing bytes at terminal.input.
The earlier capture could not discriminate at all because it recorded no
shiftKey; this one records it on 10 of 10 keydowns with code populated.

One physical Shift+T produces two shifted Process/229 keydowns. Under the
pre-#12265 classifier each synthesizes {key:'Enter', shiftKey:true}, which
the real policy resolves to sendInput '\x1b\r' — twice, giving 1b0d1b0d,
the two escapes the known-bad ed96881b0d1b0d contains.

Mutation is the retained pre-12265-process-shift.patch applied to HEAD, not
an authored one: patch -p1 applies clean and diffs identical to the mutant
copy. Arms are copies; shared source hashes the same before and after.

The English arm stays clean under both modules, so the mutation
discriminates by language rather than by harness — and a real Shift+Enter
through the same rig yields exactly ['\x1b\r'] in every arm, so a silent
pristine result means the code is quiet rather than the harness dead.

Scope: 1b0d1b0d is measured at the renderer boundary. The capture recorded
no PTY bytes — window.api.pty is frozen on shipped builds and the onData
channel needs a build-time flag — so this shows the renderer producing the
two escapes that payload contains, not a re-observation of the payload.

* docs(native-chat): narrow this file's disclaimer to what is now true

It said "THIS OWNS NO REPORTED ROW". Half of that is stale: the remount site
is now the attributed owner of #12118 and STA-3219. On real Windows TSF the
questionActive swap aborts a live composition — the old node gets only a
blur and no compositionend, the text returns as committed, and the next jamo
yields 아ㄴ rather than 안.

The other half holds. This file pins the opposite property, that the text
survives, which is the half those reporters already agree with. Mutation
shows the gap rather than asserting it: deleting the unmount entirely leaves
three of four tests green, because every substantive assertion is
after.value === … and a composer that never unmounts keeps its value.

Also records why the abort cannot be asserted here. The DOM exposes no
observable separating committed text from a live preedit — value is the same
string either way, there is no EditContext, and the only composing-ness
state is a per-instance ref discarded with the node. A test pinning "no
compositionend fires" would be an anti-guard: red the day it is fixed.

The cadence objection is kept, since it is now the open question rather than
the reason for exclusion.

* refactor(terminal): drop the unread isComposing field from XtermBypassEvent

Added by #6396 for terminal IME candidate handling that this branch has since
removed. No production or test code reads it, and the policy is safe without it:
during composition `key` is 'Process', so the non-ASCII printable checks that
would care never match.

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

* fix(native-chat): keep the composer mounted through an in-flight IME composition

A question card replaced the composer outright
(`{questionActive ? null : <NativeChatComposer/>}`). Unmounting the field
mid-composition aborts the composition in the OS: the node is detached before
`compositionend` can fire, the preedit returns as committed text, and a resumed
Hangul syllable degrades — 아 then ㄴ yields `아ㄴ`, never `안`.

Confirmed in rasterised pixels on Windows with a real MS Korean IME, at both
v1.4.171 and the reporter-era v1.4.164 (the swap block is byte-identical
across them): the preedit underline present before the swap, the composer
visibly absent during it, and the same glyph back afterwards WITHOUT the
underline — committed, not composing.

The swap is now deferred while a composition is in flight, which is what
editors that survive IME do: ProseMirror gates DOM work on `view.composing`,
CodeMirror protects the composing subtree from redraws. Hiding instead of
unmounting does not work — `display:none` and `visibility:hidden` both blur the
focused element and abort the composition the same way.

The hold releases on `compositionend`, which browsers also fire on blur, so
clicking into the card's own answer input yields the input region immediately;
with nothing composing the card still replaces the composer at once, so no
stray "Send a message" appears beside a question.

The existing characterization test flips to a regression guard: it pinned the
node being destroyed, which was the defect. Node identity is the load-bearing
assertion — value-only checks are trivially satisfied by a composer that never
unmounts and cannot tell a held composition from a destroyed one.

The typing-redirect handler moves to its own hook. That is not cosmetic: both
touched files sat at the 400-line cap, and `max-lines` suppressions are
forbidden, so the room had to come from a real extraction.

* fix(macos): opt Orca out of AppKit automatic period substitution

macOS "Add period with double-space" (`NSAutomaticPeriodSubstitutionEnabled`,
on by default) is applied by AppKit's text input system. Native terminals never
join that system; Chromium text fields do, so xterm's helper textarea inherits
it and a double space arrives as `". "` — a period nobody typed, handed straight
to the PTY (#11504).

Chromium answers AppKit for quote and dash substitution and defaults both off,
but declares no period accessor at all, so AppKit applies that one without
asking. This user default is the only lever: there is no per-field or
per-webContents opt-out to prefer over it. Writing the key into Orca's own
defaults domain overrides the global value for this app alone and leaves the
user's system-wide setting untouched. It necessarily covers every Orca text
field, not only terminals — AppKit offers no narrower scope, and that tradeoff
is deliberate rather than accidental.

Measured on the reporter's own build v1.4.161: with the preference ON, typing
a,b,space,space yields `onData ["a","b"," ",". "]`; with it OFF the same arm
yields two spaces.

Note the issue's causal model is wrong and this fix does not follow it. It
claims the substitution only fires with a CJK input source and never with ABC.
The measurement is the inverse — every Korean arm is clean and the ABC arm is
the one that fires — so the fix is not conditioned on input source.

NOT YET VERIFIED ON HARDWARE. The unit tests inject the writer, so they prove
the call is made on darwin and skipped elsewhere; they do not prove AppKit
honours an app-domain override for this key. That check is outstanding.

* fix(xterm): keep a live composition across a lone Cmd press on macOS

CompositionHelper.keydown exempted keyCodes 16/17/18 from tearing a composition
down, which covers Shift/Ctrl/Alt but not macOS Meta — 91/93 in Chromium, 224 in
Firefox. A lone Cmd press mid-composition therefore reached
_finalizeComposition(false), which dropped the preedit overlay's `active` class
and committed the live syllable early. macOS keeps the marked text alive across
that press, so no later compositionstart re-arms the overlay and the rest of the
word composes invisibly.

Measured on hardware (m4air, macOS 26.5.2, Apple M4, 2-Set Korean) with the Cmd
posted as a CGEventType.flagsChanged, which is what a physical modifier emits.
AppleScript `key code 55` posts nothing a browser can see — a bare `key code 56`
for Shift is equally silent — which is why no capture in the corpus ever reached
this branch. Three arms, same build otherwise: overlay live throughout with the
exemption, dark and prematurely committed without it, live again with it
restored. Evidence under
.tmp/ime-handoff/swarm-scratch/wave31-cmd-preedit/evidence/.

The fix cannot widen past a lone modifier: only a standalone press reports these
keyCodes, and a Cmd chord during composition is reported by Chromium as 229,
which was already exempt. Cmd+A still ends the composition, via the IME's own
compositionend. Ghostty draws the same line, returning early from flagsChanged
under hasMarkedText() for every modifier including Super.

Orca's terminal pane was never affected — shouldSuppressTerminalModifierKeyboardEvent
drops a standalone Meta keydown before xterm sees it, and deleting only 'Meta'
from that set is what flipped the hardware arm to broken. The popout preview
terminal and mobile's webview install no such guard and did reach the teardown.

terminal-ime-xterm-composition-commit-overlap.test.ts asked its fixer to update
the two Cmd arms to the values it named as correct; both now emit a single ['한'].

* test(native-chat): drop two byte-identical duplicate cases

`4632b86919d` copy-pasted two cases twice into the same describe block:
`retains carry across a same-frame non-Enter keyup before redispatch` and
`expires carry before a deliberate Enter after the next frame`. Each pair is
byte-identical — same title, same body — so the copies asserted nothing the
originals did not.

This is what has been failing `static analysis` on this branch since 2026-08-06:
`oxlint vitest(no-identical-title)` reports both under `--deny-warnings`, and
`verify` fails solely because it requires static analysis to pass. Every other
gate in `verify` was already green, including typecheck, xterm patch sync, the
full test shard set, and both package jobs.

12 cases still pass in the file.

* test(e2e): skip the WebGL arm when no WebGL renderer exists

The #12164 probe runs two arms, webgl and dom, and closes by asserting the
active renderer is the requested one. That assertion is right for the dom arm —
it is what proves the pane actually left WebGL, without which the arm is
meaningless — but headless CI has no GPU, xterm falls back to DOM silently, and
the webgl arm then fails.

The failure reads as a Korean rendering defect and is not one, so the webgl arm
now skips with the active renderer named. The dom arm keeps the assertion
unchanged.

This is the third of three checks that have been red on this branch since
2026-08-06. `static analysis` and `verify` were fixed in c51c6b5837e; the CI log
shows this job as 1 failed / 1 passed, the pass being the dom arm.

* chore(lint): drop five unused no-console disable directives

`check-changed-code-quality` reports unused eslint-disable directives as errors,
and these five sat above diagnostic `console.log` calls in IME test and spec
files where `no-console` is not enabled — so each suppressed nothing.

This is the second of the two static-analysis steps. `c51c6b5837e` fixed
"Enforce focused code-quality plugins" (duplicate test titles); this fixes
"Enforce changed-code quality". Both had been red on this branch since
2026-08-06, and I mistook the first for the whole job.

The diagnostic logs themselves are kept — they are what a failing IME arm prints
for a reader to inspect.

* test(e2e): cover #12164 under fractional device scale factor

Fractional display scaling was #12164's last unexplored branch, and the reason
is worth recording: earlier attempts were BLOCKED, correctly, because they
proposed mutating the Windows display scale on a remote physical machine with no
console recovery. `--force-device-scale-factor` reaches the same renderer state
per process, so nothing outside the Electron instance changes and there is
nothing to restore.

The hypothesis was specific: `프프로로젝젝트트` is what a half-pixel cell boundary
could produce on a 2-column glyph, and nothing else in the suite varies dpr.

Measured at 1.25 and 1.5, both under WebGL: ink extents 25/21/16 with identical
ink groups, matching the scale-1 run. No doubling.

The arm self-certifies before asserting — if the flag does not take, the test
fails rather than silently measuring at dpr 1. That matters here: the sibling
spec's WebGL arm went two days reporting a missing GPU as a Korean rendering
defect precisely because a silent fallback looked like a result.

* fix(terminal): match Mod+letter shortcuts by physical key, not IME-rewritten key

With a CJK input source active, macOS and Windows report the physical key through
`code` but rewrite `key` to the layout's character: Korean 2-Set turns Cmd+C into
`{ key: "ㅊ", code: "KeyC", metaKey: true }`. Every `key.toLowerCase() === 'c'`
match misses it, so the shortcut is not recognised and xterm encodes the chord as
PTY input instead — issue #13033 reports `ESC[12618;9u` and a terminal that jumps
to the bottom, because user input scrolls the viewport.

This is the same key-vs-code confusion that owned #12171, where a `Shift+T`
typing ㅆ was read as Enter for want of a `code` guard, so the fix is the same
shape: trust `code` when it is present, fall back to `key` and then the legacy
`keyCode` when it is not (Chromium omits `code` on synthetic and some keypress
events, and `keyCode` keeps its US value even when `key` is rewritten).

Applied to the four terminal-side sites, including the dashboard pop-out, which
#13033 called out specifically as having its own key handler:
  pty-connection.ts            Cmd/Ctrl+C copy guard
  keyboard-handlers.ts         Cmd+G search navigation
  agent-interrupt-inference.ts interrupt inference
  preview-terminal-key-handler.ts  pop-out paste

Nine further `key.toLowerCase()` letter matches exist outside the terminal
(TaskPage, editor, GitHub composer, browser markup). They have the same defect
and are deliberately left for a separate change rather than widening this one.

An existing case, `matchSearchNavigate > returns null for wrong key`, overrode
only `key` and left `code: 'KeyG'`, so it began passing for the wrong reason. It
now overrides both — which is what "wrong key" means once matching is physical —
and a companion case pins the Korean-rewritten chord still matching.

#13033 was closed NOT_PLANNED; the reporter's event shapes drive the new test.

* fix(renderer): match every Mod+letter shortcut by physical key, not IME-rewritten key

Completes the previous commit. A CJK input source rewrites `event.key` while
`event.code` keeps the physical key, so `key.toLowerCase() === 'z'` and friends
silently stop matching — the shortcut is not recognised and the keystroke falls
through to whatever handles unclaimed input.

The helper moves to `@/lib/ime-latin-shortcut-key` first: it now serves the
editor, GitHub composer and browser markup, and importing terminal-pane
internals into those would be the wrong direction. `lib/` already hosts
`ime-composition-keyboard-event` for the same reason.

Nine remaining sites, all previously unreachable under Korean/Japanese/Chinese/
Vietnamese input:
  TaskPage, ActivityPrototypePage, ProjectViewWrapper   Cmd+F search
  useMarkupKeyboardShortcuts                            Cmd+Z undo
  GitHubMarkdownComposer, RichMarkdownLinkBubble,
    rich-markdown-link-shortcut                         Cmd+K link
  native-chat-shortcut                                  Cmd+J
  rich-markdown-key-handler                             Cmd+Shift+X

Six of the nine test `!== 'letter'` as early-return guards and three test
`=== 'letter'`; the negation is applied per site, since a blind substitution
would have inverted six of them.

Full suite: 4249 files pass. Three files fail locally and none is caused by this
change — the branch touches no file under `src/main/` or `src/relay/`, all four
failures reproduce on an unmodified tree or pass in isolation (the worktree
poller passes 21/21 alone, so it is full-suite parallelism), and all 16 CI test
shards are green.

* docs(ime): scope the IME composition rules to the terminal-pane directory

#11893 proposed adding these to the root `AGENTS.md`, which every agent loads on
every task regardless of what it is doing. They only bind keyboard handling, the
composer and the terminal input path, so they belong next to that code —
`tests/e2e/AGENTS.md` already establishes the nested convention here.

Kept from #11893: range-derived commits, guarding above the key dispatch,
the `attachCustomKeyEventHandler` / `CompositionHelper` interaction, no
normalization at commit, and the recorded-trace evidence bar.

Added from defects found since it was written:
- match shortcuts on `event.code`, not `event.key` (#12171, #13033)
- `keyCode === 229` means an IME owns the press
- do not unmount a field mid-composition, and hiding is not a fix because
  `display:none` blurs and aborts it too (#12118, STA-3219, #11332)

The evidence bar now also names the mutation check, since a test that survives
deleting the code it guards is guarding nothing — a failure this effort hit more
than once.

* fix(terminal): gate Ctrl+Enter CSI-u on a negotiated pane, porting #12462

Found while scoping the rebase onto `main`: #12462 landed on 2026-08-06 and
fixes a real defect this branch does not carry. Ctrl+Enter emitted
`\x1b[13;5u` unconditionally, so a pane that never negotiated the kitty
keyboard protocol — local Windows ConPTY, plain shell — printed the escape
verbatim into the prompt.

This branch deletes `terminal-ime-deferred-newline.ts`, which is one of the
files #12462 touched, so a rebase resolving those conflicts by taking our side
wholesale would silently reintroduce the defect. Porting it forward now means
the fix survives the rebase however the conflicts are resolved.

Mirrors the Shift+Enter guard already here: local ConPTY falls back to the
legacy CR every emulator sends, and a negotiated pane keeps the chord, so the
fallback is scoped to panes that cannot receive CSI-u rather than to Windows.

NARROWER THAN #12462 BY ONE CONDITION, deliberately. `main` also allows CSI-u
via `hasCtrlEnterCsiUAuthority()` (trusted consumer evidence, #12329); that
helper and its plumbing do not exist on this branch. Omitting it is the
conservative direction — an authorised pane gets `\r` instead of the chord,
rather than an unnegotiated pane printing an escape — but it should be restored
when the two histories are reconciled.

Test covers both directions and is mutation-checked: forcing the gate open
fails it, so it cannot pass by construction.

* fix: reconcile two more fixtures main moved while the stack waited

Both caught by CI, not locally, and the reason the local run missed one is
worth recording:

1. `browser-toolbar-profile-dialogs.ime-enter.test.tsx` did not pass
   `useNativeUserAgent` / `onUseNativeUserAgentChange`, which `main` added to
   `BrowserToolbarProfileDialogsProps`.

   Local `pnpm typecheck` reported 0 errors on the same commit CI failed. The
   cause was a stale `config/*.tsbuildinfo` — tsc reused an incremental cache
   from before the merge. Deleting it reproduced CI's error exactly. Any
   "typecheck clean" during this merge should be treated as unverified unless
   the cache was cleared first.

2. Localization keys for `SshDisconnectedDialog` were absent from `en.json`:
   the merge took this branch's component alongside `main`'s catalog.
   Regenerated with `pnpm run sync:localization-catalog` rather than hand-added.

* fix(mobile): regenerate the lockfile the merge resolved by taking one side

CI's `verify` failed with `ERR_PNPM_OUTDATED_LOCKFILE` on `mermaid (lockfile:
11.16.0, manifest: 11.16.1)`. The mismatch was in `mobile/`, not the root — the
root lockfile was consistent throughout, which is why inspecting it (and even
GitHub's merge ref) found nothing wrong.

Cause: during the merge I resolved `mobile/pnpm-lock.yaml` by taking this
branch's side wholesale rather than merging it, so it kept `mermaid 11.16.0`
while `mobile/package.json` came from `main` at `11.16.1`. Taking one side of a
lockfile is only safe when the corresponding manifest comes from the same side.

Regenerated with `pnpm install --lockfile-only`; `--frozen-lockfile` now passes
in `mobile/`. Verified the xterm patch entry survives intact — same hash
`4f1b42d268f3964d…` and the parent-relative path into `config/patches/`, which
is the desktop/mobile coupling that would silently break the mobile build.

Two earlier diagnoses of this failure were wrong and are worth recording: it was
not the root lockfile, and it was not a stale merge ref (a rerun reproduced it
exactly).

test(remote-runtime): run an old client and an old server against current code (#12682)
Mixed versions are the normal state of the remote-server feature: users update clients and servers independently. Until now nothing tested that. Every cross-version claim was made by code reading plus unit tests with hand-written old/new shapes — enough to catch design problems, not enough to catch a real skew regression.

This runs the REAL protocol implementations from two builds against each other in one process: the actual host methods and RPC dispatcher on one side, the actual renderer multiplexer on the other, with a transport that reproduces the production asymmetry — each side decodes with its OWN codec and drops frames whose opcode it does not know. A frame survives only if the RECEIVING build understands it, which is what makes this level sufficient without launching two apps. The old side is a genuine checkout extracted from the release tag; the extracted client was confirmed to lack a symbol that exists only on main.

Journey: subscribe, first snapshot, input reaching the process, live output, hide/reveal snapshot, transport drop, resubscribe, input landing again — across old->new, new->old, and a current/current control. Every step ends on an observed-state barrier; no sleeps. The oracle asserts the recorded step list, the exact 16-frame named sequence, negotiated capabilities, the exact input the host wrote to the PTY, rendered content, and zero decoder-rejected frames. A host method the stub lacks is recorded by name and asserted empty, so a harness gap cannot masquerade as a wire break.

Detection is proven per violation shape, and it attributes each to the correct side: an unnegotiated opcode goes red only where a decoder would reject it, a removed published field goes red only where an old client consumes it, and a legal additive field stays green in all three pairings so the harness will not cry wolf on safe changes.

It also documents the three compatibility rules in docs/reference/remote-wire-compatibility.md, linked from AGENTS.md, since they previously existed only as folklore — notably that "decoders reject unknown opcodes" is true for the desktop decoder but NOT for mobile, which silently drops them.

Deliberately scoped: terminal stream only. The session-tab sync channel is not covered, nor agent-session publications, file/Git RPCs, mobile E2EE framing, or the relay transport. Two version points, so a regression introduced and reverted between them is invisible.

CI selection was verified rather than assumed — `vitest list` confirms 0 matches under the shard's exclude and 4 under the dedicated job — because a lane silently running zero tests is precisely how a host-side defect escaped CI earlier in this series. Closes STA-3469.

Stop a duplicate headless orca serve from crash-looping and exhausting AppImage FUSE mounts (#12212)
* fix(startup): stop a duplicate headless serve from crash-looping and leaking AppImage mounts

A second Orca launch that loses the single-instance lock called app.quit()
before `ready`. That quit is deferred, so the doomed process kept booting into
Chromium's Linux display initialization, failed with "Missing X server or
$DISPLAY", and died with SIGSEGV. systemd read that as a crash and restarted it
forever; each restart re-mounted the AppImage and left the squashfuse mount
behind, until the host hit the 1000-mount FUSE ceiling and every later launch
failed.

The lock-losing launch now calls app.exit(3), which terminates synchronously
before any display init. Exit code 3 is a stable "another process already owns
this userData profile" contract, and the documented systemd unit uses
RestartPreventExitStatus=3 plus a real StartLimitIntervalSec/StartLimitBurst
window so a permanently failing launch can no longer retry unbounded.

Second-instance argv is now forwarded to the owner, and a duplicate `orca serve`
no longer asks the live headless server to open a desktop window. Desktop
activation for ordinary launches and macOS dock re-activation is unchanged.

Closes #11935

* docs(headless): clear the start limit before the scripted service starts

StartLimitIntervalSec=300/StartLimitBurst=5 rate-limits operator starts too, so
after a crash-loop trips the burst systemd refuses a plain `systemctl start` for
the rest of the window. The Upgrade and Roll back scripts run under
`set -euo pipefail`, so that refusal aborted the rollback mid-flight and left the
server down on the exact recovery path the doc prescribes.

Both scripts (and their EXIT-trap recoveries) now run `systemctl reset-failed`
first, the unit reference explains the interaction, and the crash-loop bullet
points at it for manual starts.

* test(startup): reproduce the #11935 duplicate-serve crash loop under real Electron

The committed coverage for #11935 was source-text greps, so nothing gated the
mechanism the fix rests on: pre-`ready` `app.quit()` is deferred, which is why
the lock-losing headless `orca serve` kept booting into Linux display init.

This runs two real Electron processes against one disposable profile. The
duplicate executes the lock-loss gate's own `app.*` statement, lifted out of
`src/main/index.ts`, so reverting to `app.quit()` fails the test. It also feeds
the owner's real forwarded argv through `shouldActivateDesktopForSecondInstance`.

Also record why the activation predicate matches `--serve` and not the `serve`
subcommand: an AppImage launched as `orca serve` exits at the CLI redirect
before requesting the lock.

* test(startup): wait for the owner process to exit before removing its profile

Windows holds the profile's handles for a beat after SIGKILL, so an immediate
rmSync can fail with EBUSY/EPERM.

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

* test(startup): pass the fixture marker path by env, not argv

Chromium reorders argv and the duplicate's argv is itself under test, so a
trailing positional was the wrong channel for it.

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

* test(startup): only the activation case waits on the owner notification

The exit-contract cases assert on the duplicate's own already-terminated
process, so they should not block on cross-process delivery.

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

* test(startup): drop the staged lock race, keep the real-Electron gate contract

CI proved the two-process form cannot work on a display-less Linux runner:
Chromium's ProcessSingleton needs the browser IO thread, which needs `ready`,
which needs a display. The pre-`ready` owner looked stale and the duplicate took
the lock (`expected [ 'DUPLICATE_WON_LOCK' ] to include 'DUPLICATE_LOST_LOCK'`).

Lock acquisition and argv forwarding are already covered in
single-instance-lock.test.ts. What only a real process can settle is what the
loser does next, so that is all this file now runs -- display-independent.

fix(worktrees): stop silently switching existing Windows setup scripts to Git Bash (#12406)
* fix(worktrees): stop silently switching existing Windows setup scripts to Git Bash

#6967 derived the Windows setup-runner shell from `terminalWindowsShell`. On
upgrade, any Windows user whose terminal preference resolved to Git Bash had
their existing `orca.yaml` setup script (and issue command) handed to bash
instead of cmd.exe. Scripts authored against the cmd runner — `copy`, `xcopy`,
`set VAR=value`, `if errorlevel 1`, `%VAR%`, backslash paths — broke with no
migration and no warning, and the failure looked like Orca broke the project.

The conflation is also wrong in the steady state: a terminal preference is
per-user, so two people on the same repo got different interpreters for the
same orca.yaml and no project could write a setup script that worked for all
of its Windows contributors.

The interpreter is now a property of the script, declared the standard way:
a leading `#!` line. Native Windows keeps the historical `.cmd` runner unless
the script declares a POSIX shell, so no existing script changes behavior.
`resolveSetupRunnerShell` keeps its role as the feasibility gate — a bash
runner still requires the terminal to resolve to Git Bash, since the launch
command is typed into that shell and uses MSYS `/c/...` paths.

`buildWindowsRunnerScript` now drops a leading `#!` line rather than `call`ing
it, so a declared-bash script that falls back to cmd (Git Bash missing) fails
on a real setup line instead of aborting on errorlevel at line one.

WSL worktrees, POSIX platforms, and SSH hosts are untouched.

* fix(worktrees): keep the cmd setup runner launchable from a Git Bash pane

Adversarial review of this PR found that pinning the runner format per script
reopened issue #6896 one layer down.

- `WorktreeSetupLaunch.shell` had been redefined to mean "the format the runner
  file was written in". `resolveSetupRunnerCommand` consumes it as "the shell
  that types the launch command", so a Git Bash terminal with a batch setup
  script produced `cmd.exe /c "C:\...\setup-runner.cmd"` typed into a bash pane,
  where MSYS rewrites the `/c` switch into a drive path: cmd opens interactively
  and setup never runs. `shell` is the terminal's family again; the runner file's
  .cmd/.sh extension carries the format, and a batch runner launched from a POSIX
  pane reuses the existing PowerShell ProcessStartInfo launcher.
- The cmd runner dropped a leading `#!` line and ran the rest as batch, so a bash
  script reaching cmd (PowerShell/cmd terminal, or any SSH-to-Windows host) got
  its interpreter-agnostic prefix executed before failing mid-way. It now prints
  why and exits 1 without running anything.
- A `#!` line's option flags were discarded: `#!/usr/bin/env -S bash -euo
  pipefail` lost pipefail because the runner is launched as `bash <path>`. The
  generated posix runner now replays declared flags via `set` and drops the
  duplicate interpreter line.
- Docs cover the per-user setup command in repository hook settings, which goes
  through the same `#!` rule, and describe what the `#!` line does and does not
  select.

Tests: composed launch command for a POSIX pane + cmd runner (hooks, shared
runner command, setup sequencing gate, observed-setup signal), the cmd runner's
shebang refusal, and shebang flag replay. Each fails with the source reverted.

* fix(worktrees): replay only real `set` flags and keep the gate in the pane's shell

Two round-2 review findings:

- `#!/bin/bash -l` replayed `set -l`, which exits 2 and aborted the runner under
  its own `set -e` before a single setup line ran (all platforms). Only the flags
  `set` documents are replayed now; a bare `-o` with no option name is dropped
  instead of dumping the shell-option table.
- The wait-for-setup gate picked its language from the runner file, so a batch
  runner launched from a Git Bash pane got the PowerShell gate while the agent
  startup command was already POSIX-quoted — `Invoke-Expression` cannot parse
  `'\''`. The gate now follows the pane; the runner still launches through the
  ProcessStartInfo launcher, never through bash.

feat(cli): add orca skills install and orca skills update for headless skill setup (#9201)
Adds `orca skills install` and `orca skills update` so skills can be set up without the GUI — SSH hosts, containers, CI. Previously `orca skills` had only `list` and `get`, so there was no headless path.

**Agent targeting is scoped explicitly rather than delegated to detection.** The `skills` CLI decides which agents to install into, and with `-y` and zero detected agents it takes `targetAgents = validAgents` — all ~75. That is not a corner case for a headless CLI: a fresh SSH box or container with no agent installed is the normal starting state. Measured on a bare host, the unscoped command created **52 top-level agent directories and 54 junctions** (one real payload in `~/.agents/skills`, the rest links) on Windows, and 52/53 on macOS.

The CLI now passes `--agent` derived from Orca's own detection, mapped to the `skills` key namespace, plus `universal`. Supplying `--agent` makes `runAdd` use it directly and never call `detectInstalledAgents()`, so the fan-out branch is unreachable. On a bare host it now refuses with `No coding agent detected on this host` and exit 1, creating nothing. Same command with scoping: **1 directory, 0 junctions.**

`universal` alone would under-install — Claude Code is not in that set, and 19 of 28 mapped keys write agent-private homes `universal` never touches. `--agent '*'` is the bug itself. The mapping is hedged three ways: `null` for any agent whose key could not be confirmed, `satisfies Record<TuiAgent, …>` so a new Orca agent is a compile error, and a test pinning every mapped key against the CLI's own valid list.

Fixed during review — two holes that each restored the full fan-out through a different door:
- `--agent ','` trimmed to nothing, which skipped the refusal *and* emitted no `--agent`.
- `--agent -y` passed an emptiness check, and the vendor CLI silently drops `-`-leading values, re-emptying its list.

The real invariant is argument *shape*, not emptiness, and it is now enforced at the choke point in `buildAgentFeatureSkillInstallArgs`, so no caller can emit `-y` without a usable target. `*` remains allowed — asking for every agent explicitly is a choice, not an accident. Verified with 51 hostile inputs through the built binary, each recorded argv replayed through the vendor's own parser.

Also fixed: the `ORCA_CLI_CWD` refusal now runs before target resolution (it was quoting the wrong host's agent list), and `--dry-run` is refused in a forwarded shell rather than printing a command naming the wrong machine.

Validated on a real Windows host across PowerShell 7, PowerShell 5.1, cmd.exe and Git Bash: `.cmd` shims route through `cmd.exe` and `.exe` shims spawn directly (proved with instrumented shims, not inferred), the ENOENT path produces an actionable error rather than a silent failure, and `skills update` genuinely restores a corrupted skill byte-for-byte.

Known, not addressed here — both upstream behaviours this only forwards: a partial install failure exits 0, and "no installed skills found" exits 0. Both are invisible to the headless callers this feature exists for.

fix(terminal): release an abandoned synchronized-output frame on reveal (STA-2694) (#10907)
* fix(terminal): release an abandoned synchronized-output frame on reveal

Alt-screen agent TUIs (OpenCode/OpenTUI, Codex, grok) bracket every repaint
in `?2026h … ?2026l`. Hiding a pane mid-bracket — which a worktree switch or
cold-park lands on routinely, since these brackets are written many times a
second — leaves xterm's `decPrivateModes.synchronizedOutput` latched.

RenderService.refreshRows checks that latch *before* rendering, so while it
holds, every repaint Orca owns is a no-op: the forced render-pause repaint,
the plain `refresh()` fallback, and the shared glyph-atlas rebuild all render
zero rows while the xterm buffer is perfectly correct. Release the latch at
the two reveal repaint entry points so those repaints actually paint.

Also adds an OpenCode-shaped alt-screen e2e fixture and spec. The existing
inline-TUI convergence spec covers the normal-buffer shape (live block glued
to the bottom, history scrolling into scrollback); this covers the
full-screen alternate-buffer shape, where nothing scrolls and so no row ever
self-heals through the scroll path.

Scope note: xterm arms a 1s watchdog that clears this latch on its own, so
this closes a bounded window rather than the whole STA-2694 report. The e2e
spec passes with and without the production change for that reason; the unit
tests are what pin the behavior. Refs STA-2694.

* fix(terminal): clear the render model on the plain-refocus repaint path

`schedulePaneRevealPresent` — the atlas-preserving path a plain window
refocus takes — only called `terminal.refresh()`. xterm's renderers are
diff-based: `_updateModel` early-continues on any cell whose code/fg/bg/ext
still match the cached model, so a refresh repaints nothing for a pane whose
buffer never changed. When an occluded window loses its canvas contents while
that model stays populated, the refresh skips exactly the cells that went
stale and the pane keeps compositing pre-hide pixels — until a window resize
reallocates the model, which is the repair users find by hand.

Clear the model first (`RenderService.clear()` → renderer `clear()` →
`_clearModel(true)`) so the refresh becomes a guaranteed full repaint. That
drops cached cells and glyph vertices but NOT the texture atlas, which is
shared by every same-config terminal and whose mid-stream wipe re-arms xterm's
page-merge garble race (xterm.js #4480) — the reason this path is
atlas-preserving in the first place.

Also covers the DOM-renderer fallback in `resetWebglTextureAtlas`:
`clearTextureAtlas()` is what invalidated the model on the WebGL path, so a
pane without an addon had nothing invalidate it and hit the same skip.

Scope note: the e2e spec guards buffer/geometry convergence across the
hide/reveal boundaries and adds idle-agent and headful desktop-hide cases, but
it cannot observe a stale canvas — both oracles built for that (canvas-vs-buffer
ink sampling, screenshot-vs-forced-repaint) were proven blind by injecting the
defect, and the spec header documents why. The unit tests pin the ordering and
the atlas-preservation invariant. Refs STA-2694.

* docs(terminal): hand off the STA-2694 reveal-artifact investigation

Records both fixed defects with their xterm mechanisms, the reveal/wake call
graph, why every e2e oracle for a stale canvas was proven blind, how to arm the
in-app render-desync sentinel on real hardware, and the one unverified lead
(dimension staleness) that would explain why a window resize specifically is
the repair users find. Refs STA-2694.

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

* Revert "fix(terminal): clear the render model on the plain-refocus repaint path"

This reverts commit 0f7ec4458d37010338f16e70ff06957cb335e074.

* test(terminal): add a draw-command oracle for reveal repaints, and correct the STA-2694 scope

Every pixel oracle tried for STA-2694 was blind: `drawImage` on a
non-preserveDrawingBuffer WebGL canvas returns a re-rendered copy, and
Playwright's screenshot drives a fresh compositor frame that heals a stale paint
before capture. Reading pixels is self-defeating here — the read triggers the
repaint that hides the bug.

Count the WebGL draw commands instead, by wrapping GlyphRenderer.updateCell and
gl.drawElementsInstanced on the live pane. A draw command cannot be healed after
the fact, so "did the reveal actually repaint?" becomes directly observable.
Teeth-verified: removing releaseAbandonedSynchronizedOutput from
schedulePaneRevealPresent fails the stranded-latch test.

Two findings, both of which change previously-committed claims:

1. The 1s watchdog does NOT bound the synchronized-output defect. It is armed
   only inside `bufferRows`, and `refreshRows` returns at its `_isPaused` check
   first — so while a pane is occluded nothing reaches `bufferRows` and no timer
   is ever pending. A pane hidden mid-`?2026h` holds the latch with no watchdog
   behind it, indefinitely. ed1eaf55f1's "closes a bounded window" scope note was
   wrong; this is the unbounded garble the report describes, and the fix closes
   it. Corrected in the module doc comment.

2. It refutes the diff-based-staleness hypothesis behind 0f7ec4458d (reverted in
   8d5eacecb4). `_updateModel` does early-continue per unchanged cell, but
   `GlyphRenderer.render` then copies vertices for EVERY row up to
   `lineLengths[y]` and issues ONE full-viewport draw — measured identical
   instance counts (562) for a diff-skipped and a model-cleared refresh, with
   updateCell at 0 vs 561. The DOM renderer likewise replaceChildren()s every
   row unconditionally. Clearing the model could not change what reached the
   screen, and `_clearModel(true)` zeroes every glyph vertex while
   `RenderService.clear()` fires no repaint of its own — so it opened a
   blank-viewport window (also asserted here) for no benefit.

Also keeps the idle-agent and headful desktop-hide cases from the reverted
commit, since those were independent of the refuted production change, and
rewrites the alt-screen spec header to point paint questions at this oracle.
Refs STA-2694.

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

* docs(terminal): rewrite the STA-2694 handoff after the refutation

Records that the garble window is unbounded (the 1s watchdog never arms for an
occluded pane), that the diff-based-staleness hypothesis was refuted by
measurement and reverted, why pixel oracles are structurally blind here, and the
two leads now closed by measurement (dimension staleness, lazy atlas bindings).
Refs STA-2694.

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

* test(terminal): capture visual proof of the STA-2694 stale paint

The earlier screenshot oracles were blind because they compared a revealed pane
against a repaired one and both ran the same repaint code. Capturing the defect
directly works instead, because the mechanism is self-preserving: while
synchronizedOutput is latched, refreshRows returns before reaching the renderer,
so a compositor frame just re-composites the existing canvas texture and the
stale pixels survive the screenshot rather than being healed by it.

Latch a frame, write a full new frame the pane cannot paint, and capture. The
screenshot comes back byte-identical to the pre-hide one while the buffer holds
the new frame — the buffer/screen divergence users report — and differs after
the reveal repaint runs. Asserts both halves, so it fails if either the defect
stops reproducing or the fix stops repairing it.

Refs STA-2694.

* test(terminal): note where the xterm gate-order double is pinned for real

The unit double encodes RenderService's paused-then-latch gate order, which can
drift on an xterm upgrade. Point at the e2e oracle that pins the same order
against the real renderer, so a future upgrade has a trail to the authoritative
check. Refs STA-2694.

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

* test(terminal): add a perf budget for the synchronized-output release

releaseAbandonedSynchronizedOutput runs inside resetWebglTextureAtlas, which a
streaming alt-screen TUI can reach through the terminal-output atlas recovery
path — not only on reveal. Measure rather than assert that this costs nothing.

Steady state (a TUI that closes every frame it opens): 200 bracketed frames
produce zero releases, zero extra draw calls, and an unmeasurable early-out
cost. Worst case (every reveal finds a latched frame): 50 latched atlas resets
at 0.08ms each. Both are asserted with headroom, so the guard catches a future
change that makes this scan the buffer per pane rather than flaking on machine
speed. Refs STA-2694.

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

* test(terminal): address review — drive real code paths, close vacuity gaps

CodeRabbit caught a genuine tautology in the perf budget: it timed a
hand-copied mirror of the early-out rather than the shipped function, so the
assertion would have held even if the real code grew a buffer scan. Driving
resetWebglTextureAtlases instead moved the measured cost from ~0 to ~0.03ms per
call, which is the honest number for the whole recovery; bound re-set to 0.4ms
(10x measured).

Other review fixes:
- Assert the draw counts both perf tests were measuring and logging but never
  checking, so the 'no extra draws' titles now mean something.
- Fail fast when decPrivateModes is unavailable; previously the latched test
  would pass without ever exercising the fix.
- Re-check the latch right after the worktree switch in the mid-frame test: the
  pane is visible until then, so the 1s watchdog can arm and clear it before the
  hide, making the run vacuous.
- Count scheduleRevealPresent invocations instead of returning a literal true,
  so a missing test hook no longer masquerades as a production failure.
- Assert the latch clears on every reveal iteration, not just the last.
- Make the fixture heartbeat write atomic (tmp + rename); writeFileSync
  truncates first, so a reader could see '' and read it as frame 0.
- Relabel assertRevealPixelsNeedNoRepair as the weak secondary check it is; it
  contradicted the file header by calling itself 'the decisive paint assertion'.

fix(linux): restore Ubuntu 20.04 launch — pin node-pty glibc symbols + add glibc/libstdc++ packaging gate (#9902) (#10019)
* fix(linux): restore Ubuntu 20.04 launch by pinning node-pty glibc symbols (#9902)

The bundled node-pty pty.node is compiled from source in release CI on
ubuntu-latest (glibc 2.39). glibc's 2.32-2.34 libpthread/libutil merge
relocated openpty/forkpty (GLIBC_2.34) and pthread_sigmask (GLIBC_2.32)
into libc under new symbol versions, so the from-source build bound to
versions absent on Ubuntu 20.04 (glibc 2.31). The main process imports
node-pty at startup, so the app crashed on launch. pty.node is the sole
blocker (Electron needs GLIBC_2.25; other native modules <= 2.17).

- Patch node-pty: a .symver shim pins the 3 symbols to their pre-merge
  version (GLIBC_2.2.5 x64 / GLIBC_2.17 arm64), and Linux-only ldflags
  force libutil.so.1/libpthread.so.0 back into DT_NEEDED. Guarded to
  Linux; macOS/Windows untouched.
- Add a packaging gate (verify-linux-glibc-floor.cjs, afterPack): reads
  each bundled native binary's objdump -p version needs and fails the
  Linux build if any strong GLIBC_/GLIBCXX_/CXXABI_ node exceeds stock
  Ubuntu 20.04 (glibc 2.31 / GLIBCXX_3.4.28 / CXXABI_1.3.12). Catches
  GLIBC_ABI_DT_RELR, rejects GLIBC_PRIVATE, skips weak needs, fail-closed.
- Docs + tests; the lazy sherpa-onnx speech prebuilt (GLIBCXX_3.4.29,
  never loaded at launch) is a documented libstdc++-floor exemption.

* fix(linux): assert DT_NEEDED provider deps in the glibc-floor gate

Harden the packaging gate (flagged in adversarial re-eval): the version-floor
check alone can false-pass if the patch's forced `-l:libutil.so.1` ever silently
drops — the pinned openpty@GLIBC_2.2.5 still resolves from libc's compat alias at
build time, but fails to load on Ubuntu 20.04 where openpty/forkpty live only in
libutil. The gate now also asserts that any binary importing openpty/forkpty
keeps libutil.so.1 in DT_NEEDED. Validated on a real symver-pinned .so with
libutil dropped (now fails) vs. present (passes). Documents the recommended
real-host smoke-test follow-up.

docs(headless-server): add upgrade SOP for orca serve on Linux (#9575)
* docs(headless-server): add upgrade SOP for orca serve on Linux

The headless Linux guide covered install/run/systemd but had no upgrade
section, leaving operators to guess how to move to a new AppImage without
losing state.

Add an "Upgrade" section documenting the manual SOP (serve mode never
auto-updates) and one troubleshooting bullet:

- State lives under the service user's ~/.config (orca + Orca dirs),
  independent of /opt/orca, and orca-data.json is forward-migrated on load,
  so a forward upgrade is safe.
- Replace the binary with an atomic same-filesystem rename (download to
  .new, verify, mv) — never curl -o over the FUSE-mounted live binary.
- Back up the whole .config before upgrading, because rollback is NOT
  binary-only safe: an older build strips newer orca-data.json fields it
  doesn't recognize, and the .bak.* ring is corruption-recovery, not a
  pre-upgrade copy.
- Note there is no headless version command; track the release tag instead.

* docs(headless-server): harden the orca serve upgrade/rollback runbook

Address CodeRabbit review on #9575:

- Fail closed: run the upgrade block under `set -euo pipefail`, remove any stale
  `.new` file before download, and gate the atomic `mv` on an explicit ELF check
  so a failed/partial/non-ELF download can never be promoted.
- Keep /opt/orca/VERSION tied to the installed binary: a single `TAG` variable
  drives both the download URL and the recorded VERSION, saved as VERSION.prev on
  upgrade and restored on rollback so the audit file never drifts.
- Crash-loop troubleshooting now points to Roll back first (restores the
  pre-upgrade orca-data.json) instead of re-running Upgrade.

Add native chat skill picker with host-aware discovery (#9480)
* Add native chat skill and command picker with host-aware discovery

Adds a unified, keyboard-first skill and command picker to native chat that:

- Uses agent-native invocation syntax (slash for Claude/OpenClaude/Grok, dollar for Codex)
- Discovers skills only on the pane's execution host (local, WSL, SSH-unavailable, or runtime)
- Groups or separates commands and skills per agent configuration
- Deduplicates by canonical path but preserves visibility through all contributing roots
- Handles IME composition, loading states, and errors without claiming PTY-level control
- Records picker telemetry (open, item accepted, send classification, discovery outcomes)
- Extends shared agent profiles to define per-agent skill grammars and source ownership

* Remove obsolete reference and design documentation

Clean up stale design specs, implementation plans, and investigation notes from
docs/reference/. These documents predate the current implementation and are no
longer actively maintained or referenced by the codebase.

* Extract shared skill discovery utilities and add skill invocation envelo

- Move skill comparison and source classification to shared module for native/WSL reuse
- Extract display text sanitization to prevent control/zero-width character spoofing
- Add native-chat command envelope parser and surfacer for skill invocations
- Extend discovery timeout backstop to account for WSL metadata read sequence

* Localize skill picker UI for Spanish, Japanese, Korean, Chinese

Translate skill picker UI strings including commands, skills, loading
states, error messages, and scope labels for the new skill picker feature
across four language locales.

* Fix skill picker bugs and improve code robustness

- Fix i18n plural handling: rename `count` to `sourceCount` to prevent unintended plural-key resolution in localized strings
- Fix skill discovery array mutations: copy `root.providers` to prevent bugs during dedup merge
- Fix image attachments being silently dropped when message text starts with /skill or agent prefix
- Extract `quoteBashString` utility for WSL command code reuse across builders
- Add line-separator safety characters (0x2028/0x2029) to skill display filter
- Remove stale doc reference links and clarify inline comments

* Add reference docs for git compatibility and headless Linux server setup

Track previously untracked operational guides in `docs/reference/` that
explain Git binary compatibility requirements across host types and how to
run `orca serve` on headless Linux. Update AGENTS.md and README.md to link
to these references.

fix(worktrees): stop surfacing prunable git worktrees as live workspaces (#8409)
* fix(worktrees): stop surfacing prunable git worktrees as live workspaces

A worktree still registered in git but whose directory was deleted
(git's `prunable` state) was enumerated as a normal workspace,
producing repeated pty:spawn DaemonProtocolError / fs:readDir ENOENT
loops and a blank pane.

- Parse the `prunable` porcelain field (Git >= 2.36) in both the main
  and relay worktree-list parsers.
- For Git < 2.36 (no `prunable` field), probe each linked worktree
  path for existence on the fallback line-block path, skipping locked
  registrations to mirror git's own prunable rules.
- Omit prunable worktrees from the detected-workspace enumeration only;
  removal/cleanup flows keep seeing them.
- Extend the real-binary compatibility contract with the 2.36
  `prunable` boundary.

Fixes #8389

Claude-Session: https://claude.ai/code/session_018Rg1Bpq4GGwmz613hq6RSD

* fix(worktrees): pin the prunable/locked porcelain annotations to their real Git 2.31 boundary

The prunable and locked annotations landed in Git 2.31, five releases
before `worktree list -z` (2.36); only -z defines the capability
fallback boundary. Correct the compatibility contract so a future
matrix entry in the 2.31-2.35 range passes, and reword the fallback
comments: on 2.31-2.35 the annotations still parse and the existence
probe is a backstop; only Git <2.31 relies on it outright.

* fix(worktrees): omit prunable registrations from the Space scan

A prunable registration has no directory to size or reclaim, so Space
rendered it as a dead "Missing" row whose checkbox stayed disabled with
no prune/remove affordance (reported on macOS after a reboot cleared
/private/tmp under 16 registrations). Skip prunable entries in the scan,
matching the workspace enumeration; removal flows list worktrees
separately and still see them.

fix(terminal): kill agent descendant processes on session teardown (STA-1800) (#8706)
* fix(terminal): kill agent descendant processes on session teardown (STA-1800)

Agent CLIs spawn tool children in detached process groups that PTY
SIGHUP can never reach. Killing an agent session (tab close, retire,
sleep) left those children running as orphans — eight orphaned git
processes burned ~8 cores for up to 11.5h under the agents-running
keep-awake and drained a battery to 8%.

New pty-descendant-termination module: snapshot the ppid tree BEFORE
signalling (a dead root's descendants reparent to pid 1 and become
unfindable), SIGTERM the root group and every descendant, then after a
2s grace SIGKILL survivors gated on a pid+start-time identity re-check
so a recycled pid is never signalled. Snapshot is bounded and never
rejects; failures degrade to today's shell-only kill.

Wired for agent sessions only (plain terminals keep nohup semantics) at
all three POSIX kill sites: local provider shutdown, daemon
TerminalHost immediate kill (the pty:kill path — force-kill bypassed
Session.kill entirely), and daemon Session graceful kill.

Verified live in the built app: an agent pane with a detached-pgid
child; the child survived on the unwired build (three control runs) and
dies within ~5s with the fix. Windows ConPTY and SSH-hosted PTYs keep
the previous foreground-tree contract (documented follow-ups).

feat(ssh): support Kerberos/GSSAPI hosts via the system OpenSSH transport (#7507)
* feat(ssh): support Kerberos/GSSAPI hosts via the system OpenSSH transport

ssh2 has no gssapi-with-mic support, and adding it would mean forking its
protocol layer plus packaging the kerberos native module for three
platforms. Instead, route GSSAPI hosts through the existing system-OpenSSH
transport, which delegates Kerberos (tickets, SSPI on Windows) to the
platform ssh binary.

Two tiers, because RHEL-family distros enable GSSAPIAuthentication
globally in /etc/ssh/ssh_config and ssh -G therefore reports it for every
host:

- Targets whose ~/.ssh/config Host block explicitly sets
  GSSAPIAuthentication yes (imported as target.gssapiAuthentication) try
  system ssh first, falling through to ssh2 so key auth and credential
  prompts still work when no ticket is available.
- When ssh2 exhausts key/agent auth and the ssh -G-resolved config
  enables GSSAPI, retry over system ssh before prompting for credentials,
  so Kerberos-only hosts on distro-default configs connect without a
  password prompt. Hosts where keys work never leave the ssh2 path.

Manual targets flagged for GSSAPI pass -o GSSAPIAuthentication=yes
explicitly since they bypass ssh_config. Both tiers work headless (no
credential callbacks required).

* fix(ssh): harden GSSAPI transport selection (review fixes for PR #7507)

Review fixes on top of the Kerberos/GSSAPI feature branch (s546126/kerberos-ssh):

- HIGH: reset useSystemSshTransport on the ssh2 fall-through. doSystemSshProbe
  sets the flag before spawnSystemSshCommand, which throws synchronously when no
  system ssh binary is on PATH (outside the probe try/catch). The proactive
  fall-through previously reset only 2 of 3 transport fields, so exec/sftp kept
  routing through the failed transport - breaking GSSAPI on Windows-with-Git-ssh
  and headless Linux.
- MEDIUM: throw a cancellation error (not the stale ssh2 authError) when a
  disconnect supersedes the reactive probe mid-flight, and guard connect()'s
  catch on disposed, so a deliberate disconnect is not overwritten with
  auth-failed.
- MEDIUM: skip the encrypted-key passphrase prompt when the GSSAPI fallback
  applies, so a Kerberos ticket is tried before prompting; the general prompt
  still fires if the probe fails.

Adds 3 mutation-verified regression tests and hardens two existing tests to
assert the probe actually ran. Not connected to any PR remote.

fix(agent-hooks): make Windows cmd hook launcher directly spawnable (#8430 regression) (#8737)
Codex, Antigravity, and Devin launch their agent-hook `command` as a program
(argv[0]), not through cmd.exe. PR #8430 changed wrapWindowsCmdHookCommand to
emit an `if exist "path\." (drain) else if exist "path" (call "path") else
(drain)` compound whose argv[0] is the cmd builtin `if` — unspawnable — so every
Codex/Antigravity/Devin hook (SessionStart, UserPromptSubmit, Stop, ...) failed
with "hook exited with code 1" on Windows starting in v1.4.138.

Revert the cmd-safe fast path to the bare, directly-spawnable .cmd path (the
proven pre-#8430 form). A cmd-builtin drain and direct-spawnability are mutually
exclusive, and nesting cmd.exe /d /c breaks large-payload draining; the
missing-script stdin drain stays on the encoded-PowerShell fallback (used for
spaced/non-ASCII paths). Upgrades self-heal on first launch: startup install()
unconditionally rewrites the command and Codex trust entry, sweeping the old
compound form.

Add a platform-independent regression guard (launcher must resolve to a real
file, never a cmd-builtin fragment), update the lifecycle test + docs, and fix a
stale Devin comment.

fix(agent-hooks): drain stdin before hook script early exits so agents never hit EPIPE (#8430)
* Fix hook scripts to drain stdin before any early-exit path

Generated agent hook scripts and missing-script launchers could exit
successfully before consuming the payload written to their stdin,
leaving the writer with a broken pipe (EPIPE/ERROR_BROKEN_PIPE) once
the reader closed early. Capture stdin (or drain it via a shared
epilogue/fast-path guard) before any whole-script success exit across
all POSIX, batch, PowerShell, and Git Bash launcher variants, and add
a cross-agent lifecycle test suite plus a live Electron verification
script to guard the contract going forward.

* Harden hook scripts against unreadable managed scripts and add a Claude/

- Extend the POSIX launcher guard to also require `[ -r ]`, not just `-f`/`-x`,
  so an executable-but-unreadable managed script still drains stdin instead of
  erroring or silently misbehaving.
- Add a verifier case (`verifyClaudeDevinSkip`) that spins up a local HTTP
  server and confirms the Claude hook never forwards a request that Devin
  already imported, catching accidental double-forwarding.
- Update installer-utils tests and stdin-lifecycle docs to match the new
  readable-file guard and the added verification case.

* Fix hook-launcher verification to derive script paths from the installed

Extract the quoted path from the launcher's `if [ -f '...'` clause instead of
reconstructing it via join(home, ...), so missing/failing-script test cases
can't silently fall through to the real script if the install layout changes.

Fix mobile terminal query reply authority (#8227)
* Fix mobile terminal query reply authority

* fix(terminal): harden mobile query reply handoffs

* fix(terminal): exclude passive mobile query responders

* fix(terminal): gate mobile query replies on host capability

Older hosts strip terminal.send's inputKind (zod drops unknown keys), so a
forwarded xterm reply would land as ordinary floor-taking shell input. Hosts
now advertise terminal.query-reply-input.v1 via status.get and mobile drops
replies unless the host advertises it (pre-fix behavior). Also documents the
bounded desktop-to-mobile handoff double-reply residual.

* fix(terminal): advance snapshot seq across recovery snapshots

The pending-overflow recovery loop trims buffered output against
recovery.seq while query replay and boundary strips kept using the
initial snapshot seq. Unreachable under today's control flow (no await
separates the initial-overflow consume from the loop), but the stale
seq would silently drop covered query replies if that ordering ever
changes. Track the seq that actually covered the buffered chunks.

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.

Working plan for the orca-performance branch: verified architecture
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.

* 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.

Skips the scan-tail copy and full-chunk walks when a chunk cannot contain

positive micro-optimization on the daemon per-chunk path; 641 daemon tests
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.

* 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.

* Gates: tolerate+count Bugs B/C in deep mode; drop inverse from reconciliation tail

- 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.

Regex uses String.fromCharCode(27) to stay oxlint no-control-regex clean.

* 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.

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.

* 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.

Mobile → Network Interface section. The mobile pairing screen
("Step 2 of 2 — Pair this computer") had its own copy of the same
Select-based dropdown that did not support manual address entry. A
user trying to pair with a Tailscale MagicDNS hostname from the
pairing screen could not enter it.

Extract the typeable combobox into a shared
`NetworkInterfaceCombobox` component. Both surfaces now render the
same Popover + Command with manual address entry, the `Use "..."`
row, the inline validation error, and the `(custom)` trigger label.
Settings keeps its own Generate QR button, Refresh + Tooltip, and
Tailnet accordion around the combobox. The pairing screen keeps its
existing layout (label + combobox + refresh icon).

Net deletion: ~160 lines. Net behavior gain: manual address entry is
now reachable from both surfaces, not only Settings.

* style(ui): give CommandInput a visible background so the search box is not lost

The Popover content above the CommandList renders the cmdk CommandInput
with only a thin bottom border. Against a white popover background it
visually disappears, especially in the mobile pairing screen where the
popover sits inside a dark phone mockup. Add a subtle `bg-muted/30` +
`py-1` so the input row is unambiguous, without changing the input's
shape or behavior.

* fix(mobile-pairing): drop cmdk CommandItem, use plain buttons inside Popover

In `pnpm dev` HMR cycle the cmdk CommandItem `onSelect` dispatch was
unreliable — clicking the item fired the synthetic event but the parent
React state never received it, so the trigger label never updated after
the user picked a manual address or a refreshed interface.

Replace the `Command` + `CommandItem` primitives inside
NetworkInterfaceCombobox with a native `<input>` + `<button>` list
wrapped by Radix `Popover`. The list now responds to the user's first
click without any intermediate effect that could be skipped in dev mode.
The combobox keeps the same props contract, the same placeholder, the
same inline validation, and the same `Use "<address>"` row at the
bottom of the list.

Update MobileNetworkInterfaceSection.test.tsx selectors from
`role=option` (cmdk's) to `role=button` so the integration test still
asserts the right element. All 479 feature tests still pass.

* debug(mobile-pairing): log handleSelect* invocations to confirm click path

* fix(mobile-pairing): commit on pointerdown to beat Radix Popover close race

In dev mode Radix Popover's close-on-pointerdown handler occasionally
fires before React's synthetic click dispatch reaches the option button,
so the parent's selectedAddress never updates after the user picks a
manual address. Bind the commit handler to pointerdown (synchronous,
before any pointer-up / click synthesis) and call event.preventDefault()
to avoid text-selection side effects. Keep onClick as a fallback so
keyboard / touch / programmatic-dispatch paths still work.

* fix(mobile-pairing): keep manually-typed addresses across network refresh

`selectRefreshedNetworkAddress` used to fall back to the first OS
interface whenever `currentAddress` wasn't in the OS-enumerated
list — so a user who typed a Tailscale MagicDNS name saw their
selection snap back to LAN every time `loadNetworkInterfaces`
returned. Treat manual entries as sticky by passing an
`isManual` flag from the caller; `selectRefreshedNetworkAddress`
now keeps the address when the caller says the user typed it.

`MobilePage` tracks `addressIsManual` alongside
`selectedAddress`: `handleAddressChange` flips it on when the
picked address is not in the OS list, and `loadNetworkInterfaces`
passes it through so refresh keeps the choice.

* chore(mobile-pairing): remove debug logs and sync new-combobox-listbox i18n key

* fix(mobile-pairing): address CodeRabbit review on manual-address lifecycle

Three real bugs from review, plus a regression test:

1. NetworkInterfaceCombobox in MobileHero was disabled when
   `networkInterfaces.length === 0`, which locked users out of the
   only path to type a manual address during a transient empty
   discovery. Pass `disabled={false}` and let the combobox's
   own empty-state copy explain the situation.

2. `selectRefreshedNetworkAddress` returned `undefined` whenever
   `interfaces.length === 0`, even if the user had a manual
   address and `currentAddressIsManual` was true. Keep the manual
   address so a recovering discovery doesn't clobber it.

3. `loadNetworkInterfaces` could rewrite `selectedAddress` (e.g.
   when a refresh swaps to a freshly-discovered tailnet) but never
   updated `addressIsManual`, so the next refresh could revert
   the user back to LAN. Re-derive `addressIsManual` from the
   new address after every refresh.

Adds a regression test in
`mobile-network-interface-selection.test.ts` exercising the
empty-refresh + manual path.

* style(mobile-pairing): trim disabled-false comment to two lines

* refactor(mobile-pairing): replace typeable combobox with select + custom-address dialog

The Settings/MobileHero network selector used a Popover+search-input hybrid
that looked uneven and hid its validation error behind the open popover.

Replace it with a plain Select of discovered interfaces plus an
'Add custom address…' footer row that opens a small dialog for entering a
Tailscale hostname or static IP. Drops the 'MagicDNS' jargon for plainer
copy, keeps the '(custom)' trigger label, and routes all strings through
translate() with real es/ja/ko/zh translations. Removes the now-dead
buildComboboxEntries helper. Also adds the missing scrollbar-sleek class
the old list omitted (was failing pnpm lint).
