* fix(mobile-native-chat): retire an image echo glued with the send beside it

A message sent with images could render two or three times over, with the copy
carrying the photos sorting below the reply that answered it — and it never
cleared.

A send issued while the agent is mid-turn is glued onto the agent's input line
with any send adjacent to it, so the pair lands as one transcript row whose text
is the concatenation. Every retirement path then declined the pair:

- The image matcher wanted the whole row to equal the echo's text, so a glued
  row never bound. That also stranded the local preview: the phone's photo never
  reached the authoritative row.
- The exact-count path skips image echoes by design.
- The glue path excluded image echoes too, which made one a *barrier* — splitting
  the run so the text-only send beside it was left alone, and a lone match is
  rejected as an ordinary landing.

So neither echo could ever retire, and the unmatched image echo fell through to
the trailing bucket, which is what put it below the reply.

Match a glued row in the image matcher, and let an image echo take part in the
glue pass once its preview has been rebound. It stays a barrier while unbound,
so the existing guarantee is kept: an image echo never retires before its local
preview reaches the transcript row, or the photo would disappear.

* fix(mobile-chat): require image provenance for glued prefix matches

Brennan BensonandMerge Sim a9e6fb7eff fix(native-chat): stop rendering tool output as the agent's streaming reply (#17782)
* fix(native-chat): stop rendering tool output as the agent's streaming reply

A tool result could appear in native chat as a raw, un-collapsed "assistant"
bubble that never went away for the rest of the turn — on mobile it showed up
as a wall of a source file's contents, prefixed by "Exit code 1".

Providers publish a tool's stdout/error as `lastAssistantMessage` so status
cards and dashboard rows can preview what the agent just did. Native chat reuses
that same field as its live streaming bubble, so the preview rendered as prose.
For Claude the preview is *only ever* tool output mid-turn: claude-tool-fields
writes real prose exclusively at Stop, so the bubble could never contain an
actual streaming reply.

It also could not be retired. The bubble hides once a transcript assistant block
leads with the streamed text, and tool output never lands in one — so the only
remaining exit was the turn ending, which is why a long tool-heavy turn pinned it
on screen.

Carry provenance instead of changing what the status surfaces show: mark the
writes that come from a tool result/error, keep the flag in lockstep with the
value it describes through the listener merge, and have both native-chat
streaming paths ignore a flagged preview. Status cards, dashboard rows and
automation capture are untouched.

The wire field is optional, so an older host that never sends it keeps today's
behavior rather than silently suppressing previews.

3d341c132f fix(mobile): dismiss the keyboard after sending to an agent (#17059)
* fix(mobile): dismiss the keyboard after sending to an agent

Sending a message left the software keyboard up, covering the reply the
user was waiting on. Drop it once the send is accepted, on all three send
paths: the terminal live input, the buffered command input, and the chat
composer.

Gated on the tab being an agent session. A plain shell keeps the keyboard
so back-to-back commands stay typeable, a rejected send keeps it so the
handed-back draft stays editable, and the accessory shortcut row is
untouched because dismissing would pull away the row being tapped.

* fix(mobile): fence route reuse and native draft clears

* fix(mobile): preserve native draft edits before clear

* test(mobile): pin the terminal-list sweep that bounds buffered drafts

`bufferedTerminalDraftState.pruneDrafts(retainedHandles)` is the only bound on
two structures that live as long as the session screen — the buffered-draft
record and the pending-restoration map — and nothing failed when it was deleted
or when it was pointed at the raw `terminal.list` handles instead of the
retained set. Both mutations reddened 0 of 3,949 mobile tests.

Adds the wiring pin (both mutations now redden it) plus two behavioural tests
showing why the argument matters: `terminal.list` omits a chat-covered handle
while the desktop graph reloads, so the raw list drops a draft the user is
still holding while the retained set keeps it.

Neil 8cf692cf71 perf(mobile): slow certified terminal inventory sweeps (#17182)
* perf(mobile): slow certified terminal inventory sweeps

* fix(mobile): recover terminal inventory after stream teardown

* fix(mobile): keep fast sweeps while tabs drop a connected terminal

Tab snapshots are partial and only ever add terminals, so `terminal.list`
is the sole remover. With healthy sweeps slowed to 1/min, a background
terminal closed on the desktop lingered up to 60s, leaking its WebView and
leaving tabStripVisible stale.

Carry `connected`/`orphaned` through TerminalRecord and treat absence of a
connected, non-orphaned handle as a hint to schedule the authority -- never
as a decision to prune. Parked leaves and orphaned PTYs are legitimately
untabbed forever, so excluding them keeps the slow cadence from pinning.

Brennan Benson 80246238fc fix(mobile): reset recycled paragraph layout before reuse (#16692)
* fix(mobile): quantize chat pinch font scale so a zoom stops re-measuring the list every frame

A user bubble on a 390pt iPhone painted five lines inside a frame that
reserved six, with the last painted line cut through a glyph at the content
edge and "no longer needed." gone.

The paint is React Native's: a `<Text>` with no `numberOfLines` gets a text
container whose `lineBreakMode` is `NSLineBreakByClipping`
(RCTTextLayoutManager.mm). Measure lays out into `{width, CGFLOAT_MAX}`, paint
lays out into the mounted content frame — so a frame one line short does not
re-wrap, it dumps the remainder onto the last fitting line and clips it, with
no ellipsis. Reproduced on-device against the real component with the message
text held constant, so five painted lines can only be truncation.

Two conditions are each necessary, and removing either makes it vanish over
~6000 measured bubble renders: a pooled `RCTParagraphComponentView` carrying a
shorter row's content frame (`prepareForRecycle` clears `state` but not
`_textView.layoutMetrics`), and whole-list re-measure churn while rows enter
and leave that pool.

The churn was ours. `renderItem` closes over `fontScale`, and the pinch handler
committed a new scale on every gesture frame, so one zoom drove hundreds of
full-list re-measures. The pinch is composed `Simultaneous` with the list's own
scroll, so a stray second finger during a scroll started that storm at scales
the user cannot see — matching the report, whose glyph metrics are `fontScale`
1.0 exactly.

`quantizeFontScale` snaps commits to a 5% grid. React bails out of a same-value
`setState`, so gesture noise now commits nothing and a full-range pinch commits
at most ~20 times. Under the churn that produced 67 defects in 6636 bubble
renders, the quantized build measured 0 in 6064 — with a forced-defect control
bubble flagged in 100% of frames of both runs to prove the detector was live.

This removes the trigger we own; it does not close the RN recycling window
itself. That needs a one-line reset in `prepareForRecycle`, which cannot land
here without refreshing the `patchedDependencies` hash under `mobile/`.

Brennan Benson f6e16ba3f8 fix(native-chat): anchor an unmatched chat echo where it was sent (#16117)
* fix(native-chat): anchor an unmatched chat echo where it was sent

The reported symptom was old user messages replaying below every new turn, so the
conversation read as scrambled. The cause was not that the echo failed to match a
transcript row. Claude consumes a mid-turn send through a `queued_command`
attachment and writes no `type:"user"` record for it, so some echoes can never
match, and no amount of matching will change that. The cause was WHERE an
unmatched echo rendered: buildMobileNativeChatTransientData appended every pending
item after the entire transcript, so it re-read below each turn that landed
afterwards.

Render each echo directly after the transcript row it was sent against, using the
baseline the send already captures. An unmatched echo is then at worst a duplicate
in the right position rather than a scrambled one, and it stays visible. Echoes
sharing an anchor keep send order; a send with no baseline, or one whose anchor
folding dropped, still falls back to the tail.

Deliberately NOT fixed by deleting the echo. Inferring from send ordering that an
echo can never match, then removing it, loses the user's own text for a message
the agent did receive, and it cannot fire in the common case anyway - measured
drain groups are 1,017 of size 1 against 55 larger. It also escalates an existing
gap: the count pass has no baseline-tail guard, unlike the glue pass, while
`messages` is a 40-row window that head-trims, resets on reconnect and grows at
the front on loadEarlier, so a false landing there would license deleting a
DIFFERENT outstanding message.

That count-pass gap is real and left for a separate change; anchoring makes its
worst case a duplicate in place rather than a scrambled conversation.

Brennan Benson 588eec68b4 fix(native-chat): stop rendering a tool result whose call is outside the window (#15653)
* fix(native-chat): stop rendering a tool result whose call is outside the window

A tool result carries no call id, so it can only be attributed to a tool
call loaded alongside it. Both chat views read a windowed transcript tail
(mobile 40 messages, desktop 300), and the window regularly opens between
an assistant's `tool_use` record and the user-role record that answers it.
Claude also re-emits already-answered `tool_result` records at a `/compact`
boundary, long after their call scrolled out of the window.

`foldToolMessages` had no rule for those: with no assistant predecessor in
the output they were pushed through as standalone messages and rendered as
a bare, unowned block of raw tool output with no tool name — reading as a
message from nowhere mid-conversation. Sampling real Claude transcripts,
176 of 400 sessions (44%) produced one in a mobile-sized first page.

Drop a result no loaded call can own, before folding. It is not lost: it
comes back attached to its call as soon as the owning turn pages in.

Brennan Benson 98bdd653ab fix(native-chat): stop the spinner on a not-yet-flushed transcript (#16493)
* fix(native-chat): stop the spinner on a not-yet-flushed transcript

A brand-new agent session can take minutes to write its first JSONL line,
and one that is never prompted never writes it at all. The host emitted no
stream frame until the file resolved, so every native-chat client sat on a
bare spinner with the composer enabled but the transcript blank -- forever,
in the never-prompted case.

The resolve poll now reports the transcript as pending after a short grace,
and both host handlers emit a `pending: true` snapshot. It is deliberately
not a plain empty snapshot: an empty window sold as a settled read would
capture over retained history and unblock consumers that require a
trustworthy transcript (the launch-draft adoption would re-offer a prompt
the agent may already have taken).

Clients render it as the "start a chat" empty state while keeping the read
unsettled -- `awaiting-transcript` on mobile, an `awaiting` read phase on
desktop, which also stops the seed loop expiring into an error card for a
session that is simply new. New optional field only, so older clients
ignore it and still stop spinning.

Neil aa4c9c707c Refactor mobile home, worktree modal, and RPC client (#16165)
* refactor(mobile): split home modal and rpc client

* fix(mobile): restore render-phase remount key in NewWorktreeModal

The split moved the form-reset epoch from render-phase refs into
useState + useLayoutEffect, which changed when the remount key is
computed. On the render where visible flips false->true the key was
still the old epoch, so the previous session's NewWorktreeModalContent
rendered with visible === true carrying stale form state. Child layout
effects run before the parent's, so visible-gated hooks
(useNewWorkspaceRepositories, useNewWorktreeDrawerNavigation,
useNewWorkspaceRuntimeContext) fired for that stale instance before the
parent bumped the epoch and remounted.

Restore the ref-based computation so the key is correct on the first
render where visible flips true, keeping the composite open/client
epoch semantics and the file split intact.

Brennan BensonandNeil ec4687c434 feat(agents): distinguish Claude background monitoring (takes over #14205) (#16201)
* feat(agents): distinguish Claude background monitoring

Adds an optional `workingMode: 'monitoring'` discriminator for a Claude
session whose lead turn finished but which still has background shell tasks
or session crons registered. The wire state stays `working`, so older peers
that never read the field keep rendering Working.

(cherry picked from commit d5d54b4bdd)

Rebased onto current main (554 commits of drift) by Brennan Benson;
conflicts resolved by keeping both sides where main and this branch made
independent additions to the same construct.

* test(agents): cover Claude monitoring drain

(cherry picked from commit ce4d61ebf8)

* test(mobile): avoid unresolved renderer test type

(cherry picked from commit bbcfa35ff9)

* feat(agents): render Claude monitoring as a static turquoise dot

Replaces the yellow Radio glyph from #14205 with a static dot in a new
--agent-monitoring token (#8abeb7), defined once for light and once for
dark like --workspace-status-done, so the status keeps its identity when
the theme flips. Deliberately a fixed UI value: it never reads terminal
theme state at runtime.

Adds the turn-boundary notification pins. The monitoring predicate and
the turnCompletedAt stamp are computed from the same "lead said done but
the pane resolves to working" expression, so a rename can silently drop
the stamp and kill a completion notification that works today with
nothing else going red.

* revert(agents): restore the yellow Radio glyph for monitoring

Brennan chose #14205's original treatment over the turquoise dot, so the visual
goes back to nwparker's: lucide Radio in text-yellow-500 across the sidebar,
dashboard dot, cmd-j palette and agent-map ring.

Reverts only the visual surface. The turn-boundary notification pins stay — the
monitoring predicate and the turnCompletedAt stamp share an expression, so a
rename can silently drop the stamp and kill a completion that works today with
nothing else going red. The --agent-monitoring token is removed with its last
consumer rather than left dead in main.css.

Brennan Benson c7995a66ae fix(mobile-native-chat): reland glued pending retirement without the two revert causes (STA-4482, STA-4492) (#14936)
* fix(mobile-native-chat): reland glued pending retirement without the two revert causes

Relands #14665 (reverted by #14819). #14665 retired mobile pending bubbles when
two fast sends landed as one transcript row, but shipped two regressions; both
are fixed here rather than re-applied and hoped for.

1. A rejected send restored a TRIMMED composer. #14665 reassigned `text` to
   `text.trimEnd()` at the top of `sendMessage` and then used that one value for
   both the bytes on the wire and the composer restore, so a rejection put back
   less than the user typed. The draft and the payload are now separate values:
   `draftText` is what the user typed and is what `clearDraftForSend` /
   `restoreRejectedDraft` see; only the transported `text` is trimmed.

2. Sends issued during hydration were stranded forever. #14665 persisted
   `glueBaselineTrusted: false` on any send captured while the transcript was
   still loading and never cleared it, so that send could never retire and stood
   as a permanent glue barrier for its neighbours. A hydration-time baseline is
   now a placeholder (`baselineResolved: false`) that the first authoritative
   read rebases onto real rows, ordinals included, instead of a permanent
   disqualification. That is STA-4492.

The intended behavior is unchanged: one transcript user turn retires a run of
2+ adjacent text-only pending sends only when it exactly spells their normalized
concatenation, every send is bounded by its OWN transcript tail, and exact
landings, image echoes and unresolved tails stay barriers.

No wire change: `baselineResolved` and the baseline tail are client-local React
state in `pendingBySession` and are never exchanged with a host. The only
client->host difference is trailing whitespace no longer being written onto the
agent's input line, over the existing `terminal.send` params.

Refs STA-4482, STA-4492. Original PR #14665, revert #14819.

* fix(mobile-native-chat): let the untrimmed draft reach the send seam

The composer sent `value.trimEnd()`, so the raw draft never reached
`sendMessage` and a rejected send still handed back a trimmed composer —
the split of `draftText` from the transported `text` had nothing to
restore. Pass the draft through; the seam already owns the wire trim.

Also pins the array-identity contract of
`retireLandedMobileNativeChatPending`: the drafts effect early-outs on
`next === current`, and nothing tested it.

* docs(mobile-native-chat): name the hydration rebase's residual ambiguity

* fix(mobile-native-chat): stop the hydration rebase stranding a send on its own echo

Rebasing recounted the send's ordinal against the first authoritative read.
That read can already carry the send's own echo — a re-subscribe after a tab
switch or reconnect returns whatever exists now — so the ordinal landed one
past anything the transcript could supply. The bubble never cleared, it stayed
a live segment at the head of its run so no later pair could glue either, and
`earlierOutstanding` carried the inflation onto the next send of the same text.
Only the tail needs recovering; the ordinal was already counted against an
empty transcript, which is right for "no history was known". A caption-less
image echo keeps its captured tail, since it counts turns after it.

`baselineResolved` also has to mean "captured against a settled read", not
merely "not loading": a read that failed hands back an empty list that reads as
an empty conversation, and the null tail then let any row the successful read
finally brought glue-retire those sends.

* test(mobile-native-chat): pin that a resolved hydration send leaves its run glue-capable

A held send sits as a live segment at the head of its run, so the cursor can
never reach a later pair — the stuck bubble takes the whole feature down with
it. Goes red against the ordinal recount.

* fix(mobile-native-chat): pin an image echo that captured no tail, and require the settled flag

A caption-less image echo keeps its captured tail because it counts image turns
after it — but a send issued before any history was known captured null, which
counts from the top of the transcript. An old image turn then claimed the send
and bound the user's fresh photo to it, leaving the just-sent turn with no
preview. A null tail is not a boundary worth preserving, so pin those too.

`transcriptSettled` was optional and defaulted to the gate it replaced, so any
caller that omitted it silently got the pre-fix behaviour. Required now, and
threaded through every harness.

* fix(mobile-native-chat): stop an unbounded send claiming an image turn already in the read

The image-preview pass runs before the rebase, so a send captured with no
boundary matched any image turn the settled read carried — binding the user's
freshly attached photo to an old one and retiring the bubble through
landedImagePendingIds, which short-circuits the retirement path entirely.
Pinning the tail in the rebase could not help: the claim was already made.
Such an entry now waits one tick and claims against a real tail.

* fix(mobile-native-chat): never move a boundary the send already captured

An unsettled read still shows this session's own retained history — a reconnect
or a failed read keeps the conversation on screen rather than blanking it — so
sends made across one already own a correct tail. The rebase overwrote it with
the tail of the read that followed, which sits at or after their own glued row,
so `turn.index <= segment.tail` rejected every turn and the pair stayed queued
for the session, blocking every later pair in the run. Pin only a send that
captured no tail at all.

A captioned image echo is now left alone entirely: it binds its preview by an
ordinal counted over the whole transcript, so supplying a tail without
recounting left it matching nothing, forever.

* fix(mobile-native-chat): supply a boundary only to a text-bearing send

An image echo reconciles by counting turns AFTER its tail and has no other
retirement path, so the tail supplied from a read that already carried its own
echo excluded the very row it was waiting for: the "Queued" photo bubble stuck
for the life of the session and the transcript row rendered as bare marker text
with no photo. A regression against main, and against the earlier revision of
this fix that pinned only captioned echoes.

The glue matcher is the only consumer a supplied tail helps. Everything that
reconciles relative to its own tail keeps whatever it captured.

* fix(mobile-native-chat): stop one unmatchable send freezing glue for the session

The match cursor only advanced on a hit, so a head that could never match —
a pair whose glued row arrived with the read, or a send the count pass claimed
against an older row — froze the run behind it and every later rapid pair
became permanently unretirable. Two cases previously disclosed as bounded were
not bounded at all. Slide past a non-matching head, keeping the cursor
monotonic so a later turn can never take a send an earlier one claimed.

The slide widens the search, so a span cap keeps the work linear in the run
length instead of quadratic; the existing budget test now asserts that bound
rather than the old one it silently broke. Re-fuzzed at 250k seeds: the
boundary guarantee still holds.

Also corrects a comment that claimed the preview-pass filter made a photo claim
against a real tail. It does not — an image echo keeps whatever tail it
captured, so a caption-less photo can still bind to an older photo turn, as on
main.

* fix(mobile-native-chat): stop the span cap stranding a long glued run

Capping each match attempt at 8 segments did not truncate a longer glue, it
rejected it outright: a row spelling 9+ sends exhausted the loop without
reaching the end of the text and returned zero, so none of the nine retired —
and each stuck send then inflated `earlierOutstanding` for the next send of the
same text. Nothing bounds how many sends pile onto the agent's input line;
accumulation ends when the agent accepts input again, not at any fixed count.

One inspection budget now covers the whole slide instead. The first attempt
spans the entire run and always fits, so a genuine glue is never truncated;
only a run of identical prefix-matching sends can exhaust the budget, which is
exactly the case that should be cheap. The in-flight attempt may overshoot the
remainder — that is what makes the guarantee hold — so the budget test asserts
the real ceiling. Re-fuzzed at 250k seeds with runs past the budget.

Brennan Benson 68ca17e46c fix(mobile-native-chat): retire pending bubbles glued into one transcript row (mobile half of #14262) (#14665)
* fix(mobile-native-chat): retire pending bubbles glued into one transcript row

Mobile's native chat retires an optimistic pending bubble only when a
transcript user turn matches its normalized text at the expected ordinal.
When two rapid sends collapse into a single glued user row neither key
matches, so both bubbles pin below every newer reply for the rest of the
session — mobile has a parallel implementation with no glue handling at all.

Trim the send body once at the send seam so the bytes the host writes
verbatim and the reconciliation key describe the same message on every send
path, then add a bounded glue matcher: a greedy cursor walk that may only
consider transcript turns strictly AFTER each send's captured tail, so an
older turn that happens to read like the concatenation can never retire a
newer queued send.

Brennan Benson e570cade3c fix(mobile): keep polling session tabs while an active terminal is pending-handle (STA-4256) (#14623)
A terminal tab published as `status: 'pending-handle'` renders the session
screen's spinner. Leaving it requires a snapshot that carries the materialized
handle, but a certified-live tabs stream parks `poll()` unless
`hasRecoveryNeed()` says otherwise — and that predicate never considered a
pending terminal. A host that mints the handle without republishing therefore
stranded the pane on its spinner forever: measured live, zero further
`session.tabs.list` calls over 90s while `terminal.list` kept firing every 2s.

Mirrors the existing native-chat recovery-need pattern. Client-only; no wire
change.

NeilandOrca 2100fb2553 fix(runtime): cap remote git.diff and file previews at the transport budget (#14160)
* fix(runtime): cap remote git.diff and file previews at the transport budget

A remote or mobile user who opens the diff of a large image loses their whole
WebSocket, not just that request: the E2EE channel closes with 1013 when a reply
exceeds the 4 MiB outbound envelope. Two producers can exceed it unaided.

git.diff/branchDiff/commitDiff cap text with MAX_RENDERED_DIFF_COMBINED_CHARACTERS
(6M chars) -- a *renderer* budget that sits above the transport limit -- and return
base64 for previewable binaries bounded only by MAX_GIT_SHOW_BYTES, so a 10 MiB PNG
changed in place is ~26.7 MiB in one envelope. files.readPreview inlines base64 up
to 10 MiB, and mobile calls it for every image tab.

Both now measure against a budget derived from the outbound limit. The check sits in
orca-runtime-git.ts, downstream of the dedupe and of both the SSH-provider and local
branches, so a payload forwarded verbatim by an old relay is covered by the same code
and src/relay needs no change. Local and in-process callers pass no budget and keep
full fidelity.

Measuring raw bytes would not work, which is the whole reason this needs a module.
JSON escaping turns one control byte into six (\u00XX), and binary-buffer.ts sniffs
only for NUL in the first 8 KiB -- so a NUL-free file of 0x01-0x1f bytes is classified
as *text*, would pass a raw-byte cap, and would then blow the envelope. The budget is
escape-aware, with a three-branch fast path that keeps normal diffs at two native
byteLength calls and scans only the ambiguous band.

The SSH branch of readFileExplorerPreview had the same raw-vs-escaped gap: its stat
gate sizes base64 binaries, but text crossed unbounded. It now honours the same
decoded-text limit the local branch already enforced.

No wire change: GitDiffResult is untouched -- no third kind, no new field. Old clients
see an error for one request instead of a dropped connection. diff_too_large joins the
structured passthrough codes and lands on an existing error arm in both mobile
consumers and the desktop remote path; file_too_large was already handled on both.

Instruments the 1013 close, which nothing measured before, so the incidence this cap
is meant to drive to zero is finally observable. `emitter` separates a producer size
bug from a wedged link.

Known regression: remote image previews between ~3.096 and ~3.146 MB now return
file_too_large. They only intermittently worked before -- above ~3.0 MB they killed
the socket -- so this trades intermittent connection loss for a consistent error.

Test: 10281 passed in src/main/runtime + src/shared + src/main/git; mobile 3427
passed. Each of the six budget-enforcement sites is independently mutation-killed.
Escaping fixtures cover newline-dense, control-char, CJK, lone-surrogate and base64
content against native JSON.stringify. tsc clean for node, web and cli; oxlint clean.

* fix(ssh): surface an over-cap preview read as file_too_large

The stream reader aborts an over-cap read with StreamProtocolError, whose numeric
code falls through mapRuntimeError to a generic runtime_error carrying the raw
"Reported totalSize N exceeds client cap M" string. Neither preview client
recognizes that: runtime-file-client.ts and mobile-file-preview-response.ts both
key on file_too_large. It also made the two file_too_large guards directly below
the read unreachable on the streaming path.

Gives the cap its own error type so the caller can translate it, keeping the
bandwidth saving the cap exists for. A genuine protocol fault still propagates
unmasked.

Found by the readiness review. Mutation-verified: removing the translation fails
exactly the new test.

Neil 77f23b013f refactor(shared): drop the shared/types barrel and import from the real modules (#14447)
#14397 split `shared/types.ts` into 46 per-domain modules but kept the path as
a re-export barrel so the import sites did not have to change. This removes
the barrel: every consumer now imports from the module that actually declares
the type, and `src/shared/types.ts` is deleted.

Barrels hide where a type lives, make every consumer look like it depends on
the whole domain, and let an unrelated edit invalidate a module that ~2,000
files transitively import.

2,323 import declarations across 2,321 files. Rewritten mechanically: each
specifier was resolved to an absolute path via the TypeScript AST and
recomputed, rather than string-substituted, so alias forms (`@/../../shared/
types`) and per-specifier `type` modifiers survive.

Four cases the mechanical pass had to handle, each found by a gate rather than
by reading the diff:

- Modules inside `src/shared` import the barrel as `./types`, not
  `shared/types`. A pre-filter on the latter string skipped 176 of them and
  left imports dangling at a deleted file, which surfaced as confusing
  `Property 'x' is optional in type 'Repo' but required in Pick<Repo, ...>`
  errors rather than "module not found".
- The barrel RENAMED one type on the way through
  (`WorkspaceSource as WorkspaceCreateTelemetrySource`), so the original name
  in the owning module has to be re-aliased at each consumer.
- Three test files put `;(globalThis as ...)` on the line after the import.
  TypeScript parses that `;` as the import statement's terminator, so
  replacing through `statement.getEnd()` deletes it and breaks ASI. The
  rewrite now stops at the module specifier.
- A file that already imported directly from a module got a SECOND import
  from it, because the barrel re-exported those same names — which trips
  `import/no-duplicates` under `--deny-warnings`. A post-pass merges
  declarations sharing a specifier and type-only-ness; the `import type` plus
  `import` pair from one module is left alone, since that form is allowed.

Splitting one barrel import into several genuinely adds lines, which pushed
`terminal-layout-pty-ownership.ts` to 301 counted lines: its 107-character
import must wrap, and neither local type collapses onto one line (101 and 116
characters). Rather than contort a type declaration to fit a line budget,
`collectLeafIds` and `pruneLeaves` move to `terminal-pane-layout-tree.ts` —
they are pure structural operations on the layout tree and independent of PTY
ownership. `visible-worktrees.ts` similarly loses its own mini-barrel
re-export of `isDefaultBranchWorkspace`, with the four real consumers
repointed at the declaring module. No `max-lines` bypass added.

Verified: cold `tsc --noEmit` green on node, cli, and web (buildinfo deleted
first — these projects are `composite: true` and reuse stale caches); the full
`pnpm lint` green, not just bare oxlint — the narrower local check is what let
the duplicate imports reach CI; max-lines ratchet OK at 344.

Neil 583ab1601b refactor(shared): group worktree, github, and linear modules into folders (#14437)
`src/shared` is a flat directory of ~1,150 entries. The worktree, github, and
linear domains accounted for 71 of them, so finding the module you wanted meant
scanning a wall of same-prefixed filenames.

Move each domain into its own folder and drop the now-redundant prefix:

    src/shared/github-pr-types.ts    -> src/shared/github/pull-request-types.ts
    src/shared/worktree-id.ts        -> src/shared/worktree/id.ts
    src/shared/linear-links.ts       -> src/shared/linear/links.ts

This follows the existing `network/` and `new-workspace/` convention in the
same directory, which also drop the prefix inside the folder.

Whole clusters move, including tests. Foldering only part of a domain would be
worse than flat: a reader would have to check both `github/` and the flat
directory, and `github-auth-types.ts` / `github-project-types.ts` are type
modules that belong with the rest. No files with these prefixes remain flat.

Import specifiers were rewritten by resolving each one to an absolute path and
recomputing it, not by string substitution, so the `@/../../shared/...` alias
forms are handled correctly. 501 specifiers across 298 files.

Two things `tsc` cannot catch, handled explicitly:

- `github-project-types.ts` carries its own `max-lines` bypass, so its baseline
  entry is REPOINTED to the new path rather than pruned. Pruning would drop the
  bypass and then flag the new path as a fresh violation. Ratchet stays at 345.
- `mobile/` is outside `pnpm typecheck` and cannot be typechecked here
  (`mobile/node_modules` is empty). Instead every relative specifier in the repo
  was resolved against the filesystem: 174 unresolved before this change and 174
  after — identical, so nothing broke in mobile either.

The pinned `tests/e2e/.cross-version-checkouts` fixtures are deliberately NOT
rewritten; they are a snapshot of an older release and still reference the old
paths.

Verified: cold `tsc --noEmit` green on node, cli, and web (buildinfo deleted
first — these projects are `composite: true` and reuse stale caches).

Neil 4882eeb8ac rm git shim: neutralize stale wrappers without a host gate (#14255)
* Revert "fix terminal attribution shim removal edge cases (#14187)"

This reverts 585dd6d3a9. Re-landed in the next commit without the host capability gate. Nothing shipped with it, so no migration constraint.

* rm git shim: neutralize stale wrappers without a host gate

Re-lands the cleanup half of #14187: pass-through tombstones for retained wrapper paths, env/PATH scrubbing at every spawn owner, and the retired setting drop.

Only writes tombstones when the legacy directory already exists, so a clean install no longer has it created. Leaves out the terminal.attribution-removed.v1 capability gate: the tombstone neutralizes each host locally, so refusing terminal create/split against older hosts denied service without adding cleanup.

* rm git shim: surface neutralization failures and fix rollback marker

Readiness review follow-ups: warn on each failed attempt and on give-up (was silent and undiagnosable); write a VERSION marker distinct from the retired shim's '7' so a rolled-back build rewrites its own wrappers; clear a captured ORCA_REAL_* path that no longer exists so the cmd wrapper's where.exe fallback can run; stop a locked temp file masking the real error. Adds retry-exhaustion coverage.

* rm git shim: pin the cmd fallback order and correct the give-up count

Round-2 review follow-ups: string-pin that a stale ORCA_REAL_* is cleared before the where.exe fallback, and count the initial attempt in the give-up warning so it agrees with the per-attempt line.

* rm git shim: keep the split-failure toast

The revert took a toast that #14187 added alongside the gate but which stands on its own: without it a failed remote split only reaches the console and the pane silently never appears. Also pins attempt ordinals in the retry-exhaustion test.

Brennan Benson 6b84e33251 fix(mobile): trade a lease-only stream for output when leaving a chat tab (#14179)
* fix(mobile): trade a lease-only stream for output when leaving a chat tab

Tapping a terminal tab from a native-chat tab left the terminal blank. The
route subscribes the incoming handle synchronously in switchTab, while the
coverage it reads still describes the chat tab being left, so the handle gets
a `mobileInputLeaseOnly` subscribe — the host answers `subscribed` and nothing
else, no scrollback and no data frames. Input kept working because it rides a
separate terminal.send RPC.

The reconciler then cleared its covered marker (the active handle changed), so
the stream was active and uncovered — which its state machine could not tell
apart from a healthy one, because `streamActive` conflated the two. It settled
on 'none' and nothing else repaired it: the route's web-ready path bails on any
live subscription. The tab stayed blank until app restart.

Track which handles hold a lease-only subscribe and thread it into the
reconciler as `streamIsLeaseOnly`, so an uncovered handle holding one resumes
into a full stream. The covered branch is untouched, so the input lease that
keeps the chat composer from locking forever (#10681) still survives.

Neil 991a3fe963 chore(lint): update oxlint to 1.77 and enable no-op cleanup rules (#13901)
Enable eleven oxlint rules that simplify code without changing behavior, and fix
every existing violation. Each candidate was gated on measured cost rather than
assumption, so rules that regressed runtime performance or type checking were
dropped instead of suppressed.

typescript/no-redundant-type-constituents is the largest addition: 113 sites, no
autofix. Dead constituents are deleted. Where the redundant literal existed to
document intent (`string | 'all'`), it is preserved as `(string & {})`, which
keeps the autocomplete hint the original code was reaching for instead of
flattening it away. The rule also caught a broken import —
remote-shared-control-retirement-probe.ts pulled RuntimeStatus from
src/shared/types, which does not export it, so the type silently degraded to
`any`; no tsconfig covers that file, so tsc never saw it.

oxlint stays at 1.77.0 rather than 1.78.0 because .npmrc sets
minimum-release-age=4320 and 1.78.0 is younger than that window.

Rules evaluated and rejected, with what disqualified each:
- prefer-string-raw: String.raw is a runtime call, not a literal (184x slower)
- prefer-string-replace-all: 26% slower
- text-encoding-identifier-case: ~5% slower, reproducible
- prefer-spread: [...str] is 110% slower than split('') and differs on surrogates
- no-implicit-coercion: `!!x` narrows types and `Boolean(x)` does not (22 tsc errors)
- prefer-arrow-callback: arrows are not constructible, breaking `new` on mocks
- object-shorthand: rewrites source text asserted by a tracked reliability gate
- switch-case-braces: pushes ten files past max-lines, which cannot be suppressed
- no-useless-switch-case: drops `case undefined:` that switch-exhaustiveness-check needs
- arrow-body-style: 115 violations have no fix, and it breaks max-lines
- newline-after-import: false-positives on the leading-semicolon ASI idiom

electron-vite-output-contract asserted on the literal
Object.prototype.hasOwnProperty.call text; retarget it to Object.hasOwn, which
rejects inherited keys identically.

* fix(native-chat): keep assembly renders pure

* fix(native-chat): keep a transient error from stranding a revealed chat

- An error snapshot frame no longer latches frameArrived, so the in-flight

- The paged read window survives a hide/reveal; only a source change resets it.

* fix(mobile): match the trimmed native-chat retention signature

The shared retention type no longer takes `loading`, so mobile's call was an
excess-property error that broke the mobile typecheck job. Dropping it also
lets mobile inherit the desktop behavior: a stream error or dropped client
keeps the last transcript instead of swapping it for the error empty state.

* 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.

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

* 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.

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.

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

* 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,

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 61977d4517 — the preedit survives the question card

61977d4517 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 61977d4517 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 dbeecb11be

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 19a8d133db — 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 (9506039de7) and
the preedit sized to the font rather than the grid (e04e0c88da).

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).

JinjingandOrca 094d6821ef feat(native-chat): add model and effort pickers for grok (#12780)
* feat(native-chat): add model and effort pickers for grok

Grok had no session-option catalog, so the native chat composer showed no
pills and every launch ran the CLI's own defaults with no way to change them.

Adds a `GROK_SESSION_OPTION_CATALOG` (model via `-m`/`/model`, reasoning
effort via `--reasoning-effort`/`/effort`) and the discovery plumbing behind
it. Grok's selectable ids depend on the signed-in account and on `[model.*]`
config, so the seed carries only `grok-4.5` and a runtime `grok models` probe
supplies the rest as authoritative — a retired id must be droppable, since
launching one is a fatal exit rather than a warning.

Because `grok models` publishes `Default model:` and marks the row
`(default)`, the picker can name the model a fresh session is actually
running: `defaultModelIsCliDefault` plus an untracked record means no `-m`
was ever emitted, so the CLI is on its own default. That default scopes the
effort row but is never written to persisted settings — that field is what
authorizes `-m` on every later launch, and adopting a model the user never
picked would pin today's default forever, fatally so on an account without
it. `grok --help` publishes no default for `--reasoning-effort`, so the
effort value stays unnamed until something sets it.

Known gap: that refusal to persist is also a limit. An option set while on
the CLI default is dispatched and honored in-session, but reaches no later
launch — it persists under the default's id with `model` left unset, and
both `resolveNativeChatSessionOptionDefaults` and
`resolveAgentSessionOptionLaunch` bail without that key. Picking a model
explicitly persists normally. Closing this means teaching both to resolve
options from the default model while still refusing to emit `-m`, which is
the launch-args path and wants its own review.

Known gap: the picker infers "no `-m` was emitted" from its own in-memory
record, so a model reaching argv from outside it — the user's own
`agentDefaultArgs`, or a renderer reload that drops the record while the
flagged PTY lives on — leaves the pill claiming the CLI default while
another model runs. No wrong model is persisted.

Extracts `hasFlag` and `labelFromModelId`, and splits the model-probe spec
out of the commit-message registry so discovery no longer implies an agent
can write commit messages.

* docs(native-chat): note the invariant keeping modelIsCliDefault agent-safe

The flag is computed without checking the catalog, so it reads as unsafe for
the four agents with no CLI default. It is safe only because `persist` bails
unless `modelId` is truthy, which for those agents implies a tracked model.
Widening that guard would silently change persistence for every agent.

* fix: retire persisted models on mount and handle -- terminator

- When a pane mounts after model discovery has already settled, it now checks
  the cache and retires persisted models that are no longer available.
- CLI flag detection now respects the `--` option terminator, treating
  everything after it as positional arguments rather than flags.

* Fix: persist grok session options under probe-confirmed defaults

Options set under the CLI default were silently lost on restart.
Distinguish seed guesses from probe-confirmed defaults by renaming
`modelIsCliDefault` to `modelIsUnverifiedDefault`. Once confirmed,
adopt the default as a persisted flag so options survive restarts.

* fix(native-chat): close the retired-model fatal-launch paths from counsel review

Counsel report C1/C2 (High), C3, P1, C4:
- Untrack a session model an authoritative discovery dropped and gate every
  persist path, so option writes can never re-adopt a retired id (C1).
- Resolve launch defaults through the enrichment cache: a persisted model
  missing from every settled probe no longer becomes a fatal `-m` (C2).
- Serialize retirement and picks on one settings write queue that re-reads
  live state at apply time (C3).
- Stabilize onSwitchToTerminal so the session-option surface is not rebuilt
  every TerminalPane render (P1), and cap the enrichment host map (C4).

* Store agent in enrichment entry and extract token utilities

Refactor enrichment to store the agent field directly instead of
parsing it from a composite key, and extract CLI flag token filtering
into a shared utility. Use a dedicated function for tracked model ID
lookup. Improves code reuse and reduces parsing overhead.

* Rename modelIsUnverifiedDefault to adoptModelAsLaunchDefault

Move the model adoption gate into the core session-options module, where probe confirmation and discovered-model status are known. This ensures adoption decisions are gate-checked before persisting to avoid fatal launch flags, and simplifies the picker surface by moving the logic to where it belongs.

* Keep model probe evidence by agent, not host

Store probed model IDs in agent-keyed cache independent of host cache, so
evidence persists across host eviction. Prevents retired models from being
treated as valid when host cache entries are evicted.

* Store agent in enrichment entries instead of separate proof-evidence map

Model probe evidence is now tied to enrichment entries rather than maintained in a separate per-agent map, eliminating the need for eviction logic that could disconnect proof from entries.

NeilandOrca 02a1251c2d fix(native-chat): classify diff lines whose content begins with -- or ++ (#12459)
* fix(native-chat): stop diff colouring from misreading -- / ++ content lines as file headers

diffFromText skipped every line starting with --- / +++ as a file header, so a
deleted SQL/Lua '-- comment' (git emits '---<content>') or an added '++flag' fell
through to gray context with its marker still attached — and when it was the only
change, the two-marker gate dropped the coloured diff entirely.

Detect real headers structurally instead: an adjacent '--- <old>' / '+++ <new>'
pair outside any hunk. A hunk header or 'diff --git' line now also proves the text
is a diff, so a genuine single-line change renders while prose keeps the guard.

* test(native-chat): adopt #12335 diff-collision vectors and add mobile parity

Pulls in @YuriNachos's test vectors from #12335 (header-less --- deletion, an
adjacent --x/++y content pair, mobile re-export parity) and adds the spaced
-- / ++ pair inside a hunk, which the pair-only rule in that PR misreads.

* fix(native-chat): keep bare --- / +++ rules out of the diff marker count

Dropping the `---`/`+++` prefix exclusions made a bare `---` — a Markdown
thematic break or YAML document separator — classify as a deletion. Tool
results routinely carry those, so `---\na: 1\n---\nb: 2` went from correctly
rejected to rendering as a red diff.

A bare rule is never a file header (those need a path after the marker) and is
only content inside a hunk, so treat it as meta when outside one.

Fold the separate `isStructuredDiff` scan into the same pre-pass and skip
non-marker lines early, so the added guard costs no extra traversal: 5.1 -> 4.3
us per 120-line prose result, diff path unchanged.
