CI's code-quality plugins deny a second import of a module already imported in
the same file; the pre-commit hook runs a different oxlint config and did not
see it. Both failing checks were this: `verify` is a gate that only reported
static analysis, with typecheck, tests and both package jobs already green.
Reattach failure left every record untouched, including the one answer that
settles it. A shell the relay watched exit kept a live lease, so every later
reconnect fanned out an attach for it — two attempts and a ten-second deadline
each — and the set only grew, in a file written to disk.
A proven exit now retires the record. `terminated`, not `expired`: expiry is the
state the recovery grant reads, and retiring a record must not also authorise a
replacement.
Everything else is unchanged and still leaves the pane detached and recoverable,
which is the point — a not-found is also what a replaced relay answers for shells
its predecessor is still running.
Retiring a stable pane's owner authorizes a replacement that carries the pane's
agent resume payload. Until this branch, an SSH reattach failure reached that
decision as SSH_SESSION_EXPIRED, which the gone-check did not match, so it never
fired for SSH. Retiring the not-found mapping changed that: the raw
`PTY "<id>" not found` now matches, so a replaced relay answering for a shell its
predecessor is still running would retire the owner, fabricate an exit, and
respawn with the resume payload — the double resume, reintroduced by the commit
meant to prevent it.
For an SSH pane the two proving answers are the relay's own observed exit and the
expiry the reattach mints only after verifying that proof names this shell. A
bare not-found is neither, and now propagates instead: the pane keeps its owner
and surfaces as disconnected.
Local and daemon ptys are unchanged — their provider owns its ptys, so absence
really is proof. The shutdown paths that also use the gone-check are untouched:
there, "not found" is the outcome being asked for.
The covering test drove the dangerous shape directly — bare not-found, retire,
respawn with `codex resume …`. It now drives the proof, and the bare not-found
case is pinned beside it.
Deleting the relay's pane-identity comparison disarmed the recycled-id guard for
every client that has not upgraded. The relay is shared and host-side: one person
updating a host would leave their colleagues attaching by id alone, with nothing
checking it in either direction.
It is back as a FALLBACK, used only when the caller sends no incarnation. A
client that can name the shell is still fenced on that and still attaches after
moving tabs; a client that cannot gets the older, coarser check it was already
living with rather than none at all.
The two clauses inverted when it was deleted are restored, because they send pane
identity with no incarnation — the old-client shape, which should be refused. The
moved-pane property they used to contradict is pinned separately by the clause
that sends an incarnation, and reverting the override reddens it.
AGENTS.md asks for brief non-obvious comments, one line where possible. Several
of mine ran to five and eight lines of narrative on the relay's attach path,
which is the one place a reviewer most needs to scan the branching quickly. They
now say the same thing shorter.
Both gone-paths in attach() had independently spelled out the rule that proof
must name the caller's own shell. That duplication is what let the earlier fix
close one and miss the other, so the condition is now a single predicate both
ask — a change to the rule cannot reach one path and skip the other.
The renderer kept its own copy of SSH_SESSION_EXPIRED while this branch created
a shared home for exactly that token, whose whole reason for existing is that the
two copies once disagreed about an identity mismatch and the renderer respawned a
live shell. It imports the shared one now.
Not changed, after checking: the per-generation recovery budget still does not
reset on a successful reattach. Resetting it looks obviously right and is wrong —
a flapping PTY alternates failure and success, and a covering test drives exactly
that for forty rounds. The park cooldown already bounds the harm.
The lease field was declared, preserved on load, and read on reconnect — and
never written. Both spawn writers omitted it, so every lease carried only
"pty-N", the reconnect always took the no-expectation path, and the fence added
for it could not fire. The main reconnect went on attaching by id alone, which
is the replaced-relay case the fence exists for.
Worse than inert: a successful unfenced attach durably binds the pane to
whatever answered, so the wrong identity would be recorded and carried forward.
The host attests the identity at spawn and it was already in scope one line
above both writers.
The oracle for this had to pin the WRITE. Every other clause — the type, the
loader, the reader, the reconnect forwarding — was green throughout, because
each was correct in isolation; only nothing joined them. The test that covers
the spawn now seeds a host incarnation and requires it on the persisted lease,
and removing either writer reddens it.
There are two client attach routes and only one was fenced. The pane-driven
restore goes through reattachSshPtySession, which was sending the shell identity;
the relay session's own reattach — the one that reconnects EVERY known pty when a
relay comes back — goes through attachForReconnect, which sent nothing.
That is the wrong one to leave open. A relay coming back is exactly when ids have
been reissued from pty-1, so the main reconnect was the likeliest place to attach
somebody else's shell, and it was attaching by id alone.
It now sends the identity the lease recorded, which is what the lease field added
earlier was for; the two halves finally meet. Pane identity is still not sent —
only the shell's own — so a pane that moved tabs is unaffected. It also declares
exit-proof support, so a proven exit can reach the path that reattaches after a
host restart.
Callers with nothing extra to say keep the older call shape, so this does not
churn every reconnect assertion in the suite over trailing undefineds.
Enforcement lived only on the host. But the host is the party whose answer is in
question, and mixed versions are the normal state — a host that applies the rule
loosely, or not at all, could hand back an exit for a shell the pane never owned
and the client would replace a process that is still running.
The incarnation travels in the proof precisely so the asking side can check it.
A proof that cannot be tied to the shell this pane asked about is not proof, and
falls through to the disconnected pane. A pane that knows no incarnation cannot
verify anything, so it does not get to act on one either.
Both halves now apply the same rule independently, which is what makes it hold
across versions rather than only when both ends agree.
The remembered-exit route was fixed to require a present, matching expectation.
The liveness probe is the other route to the same claim, and it still answered
anyone: it fires when a pty EXISTS but its pid is gone, and under a given id a
replacement relay may hold a shell that is not the caller's at all. Its death is
then no evidence about a pane whose own shell may be running orphaned under the
relay this one replaced — and the reply authorizes replacing it.
Both routes now demand the same thing. The reap still happens either way, because
a dead shell should be cleared whoever asked; only the answer depends on whose it
was, and a caller who named a different shell is told exactly that.
Found by asking whether the guard ordering was right, after the first fix closed
only the half that had been reported.
Review found three ways the new proof could be believed too easily.
A caller that names no shell was still handed a remembered exit. That is the same
double resume in a new costume: relay A is killed leaving pty-1 alive and
orphaned, relay B mints its own pty-1 and THAT one exits, and a pane carrying no
recorded identity would be told its shell is gone — then replace a process still
running. The expectation must now be present AND match. Panes with nothing to
compare get the disconnected card, which is the direction that cannot lose work.
The proof is also gated on the client declaring it understands it. What the host
answers reaches clients that predate the reply, and one of those reads an
unrecognised attach error as neither death nor recovery — a stranded pane. Older
clients keep the wording they already act on; nothing is lost, because they could
not have used the proof anyway.
And the match is anchored on the whole grammar rather than the token, with the id
and incarnation percent-encoded. A substring test would let any text that merely
quotes the token stand in for the relay's own observation.
Two callers that key on "already gone" now also accept a proven exit, so the
liveness-probe reap does not burn a retry before reaching the same conclusion.
The oracle for the first of these was itself vacuous: `toThrow` with a negated
asymmetric matcher passes whenever anything throws at all. It now reads the
thrown message, and reverting the guard reddens it.
A bare not-found became SSH_SESSION_EXPIRED, and expiry authorizes a respawn.
But "the relay I asked cannot hand that id back" proves an exit only if that
relay is the one that minted it — a replaced relay answers exactly this for
shells still running under its predecessor. So after a relay restart, live
orphaned shells were read as dead: ownership cleared, lease expired, and the
agent resumed a second time onto a transcript its first process was still
writing to.
The relay now keeps what it actually observed. On a real exit, and on the
liveness probe that finds a pid gone, it remembers {code, incarnation} in a
bounded map and answers a later attach with SSH_PTY_EXITED instead of throwing
that knowledge away. That is first-hand, same-process evidence, and it is the
only answer that now maps to expiry.
A remembered exit for a DIFFERENT incarnation is not an answer about the caller's
shell, so a recycled id cannot report a stranger's death as its own. A crash
loses the map, which correctly reads as no knowledge rather than as death.
The carrier is the message text: the relay's error transport keeps only a message
and a numeric code, so a structured payload would not survive. It is deliberately
worded to avoid "not found", which older clients map to expiry.
Cost, stated plainly: against a relay too old to remember exits, a genuinely dead
shell is now unproven, so the pane offers the disconnected card instead of
replacing itself. That is the affordance's purpose, and it is the safe direction.
A reset relay restarts its ids at pty-1, so an id alone can name somebody else's
shell: a pane still bound to pty-1 could attach to a shell another pane was
already driving, and the two would share keystrokes and output.
The guard that used to catch this compared the paneKey and tabId frozen at spawn.
It was removed for good reason — a pane moved to another tab was refused its own
live shell, and refused as "not found", which read as death and resumed the agent
a second time. So it traded a cross-attach for a double resume.
The incarnation is the shell's OWN identity, so it discriminates a recycled id
without caring where the pane lives: both failures close at once. The relay
refuses a mismatch and is deliberately not worded "not found" — that phrasing is
what the client maps to an expired session, and expiry authorizes a respawn onto
a shell this branch just proved is alive.
Only a host-attested expectation is sent. The locally synthesized stand-in is not
stable across reconnects and would refuse a pane its own shell. An older relay
ignores the field and an older client sends none, so both stay permissive.
The tab-keyed comparator is deleted rather than left dormant, and its suite is
inverted onto the new identity: a recycled id is still refused, and a pane that
moved tabs now attaches instead of being told its shell is gone.
A lease names a shell by ptyId, and ptyId alone cannot identify one: a replaced
relay restarts its ids at pty-1, so the same id can name somebody else's shell.
This adds the missing primitive — the incarnation the HOST attested — so a later
change can tell "my shell" from "a different shell wearing its id". No behaviour
changes yet; nothing reads the field.
Only host-attested values are stored. The provider synthesizes a stand-in when a
host reports none; that stand-in is first-write-wins and is dropped when provider
state resets, so the same live shell can present a different one after a
reconnect. Recording that would later read as a different shell and strand a live
pane, so it is refused, and the synthesizer now shares the prefix constant with
the predicate that rejects it.
Leases are rebuilt field by field on load, so the normalizer had to learn the
field too — adding it to the type alone drops it on every boot, which is how a
fence ships silently permitting everything. The oracle reddens on exactly that.
While the card is up the pane keeps its durable binding on purpose, so a failed
replacement can put the card back. But main resolves a stable pane's owner from
that same binding: if the shell answers again between the failed reattach and the
click, the spawn adopts it and returns its id. Nothing was replaced, and clearing
the binding then unbound a shell that is live and attached to this very pane —
leaving it running with no durable record of what it owns.
Detected by identity: an id equal to the one we were replacing means adoption,
not replacement. Suppressing adoption outright would need a new spawn option
plumbed renderer -> transport -> IPC; the user-visible oddity that remains is
getting the old shell back rather than a new one, which is benign next to
orphaning it.
hasPty is three-state and says so: null means the provider has not listed the
host yet — ignorance, not death. The retry gate tested it with `!`, which reads
null and false alike, so it ended recovery on ignorance.
That state is not exotic: a reconnect builds a fresh provider with an empty set,
which is exactly the moment rejected frames arrive. The attempt was deleted and
no retry scheduled, and because the delivery token was already retired, no later
frame could revive it — the pane stayed dark. It also short-circuited the park
cooldown, since parkedAt was never set on an entry that no longer existed.
Only an explicit false stops us now. The proven-exit clause still pins that.
The disconnected banner was renamed but kept reading five keys under the old
component's namespace while its new strings sat under the new one — a component
translating from two namespaces at once. Keys moved across all five locales;
values and behaviour unchanged.
Two comments earn their place. durablyBoundPtyIdForPane deliberately does NOT
require the tab to still exist, unlike findTerminalTabIdForLeaf which must —
adding the "missing" check there would make arbitration retire shells more
eagerly, which is the opposite of what this change is for. And the respawn after
the proof check in the direct-SSH catch is unreachable today by construction;
saying so stops it reading as forgotten code.
The cooldown added in 124e00e8a8 was reactive: it needed a later rejected frame
to reach recovery. But retirement is ours, not the host's — a stalled source keeps
publishing the very token we retired, and acceptPtyData drops those frames before
classification. So the wake-up could never fire in the case that actually happens,
and the pane stayed dark exactly as before.
A parked PTY past its cooldown is now let through that filter. It costs nothing:
the frame is re-classified as rejected and re-retired, so no output reaches the
terminal — it only regains the ability to ask for recovery.
The test shipped with that commit could not have caught this: it woke recovery
with a fabricated NEW delivery token. Retirement holds one key per relay PTY, so
that frame overwrote the key and un-retired the original — the assertion passed
with the wake-up path fully broken. It now reuses the original token throughout,
and reverting the guard above reddens it.
Exhausting the per-generation recovery budget parks one PTY's delivery rather
than dropping the shared relay channel — right, because the channel is shared and
a retry count proves nothing. But the only escape it named was "the next relay
open", and a channel that stays healthy never gives it one. That leaves a pane
with no output and no way back, which is the exact state this change exists to
prevent; before this branch, exhaustion dropped the channel and the reconnect
ladder recovered the pane (loudly, at every sibling's expense).
The park is now a cooldown rather than a verdict: the next rejected frame after
it starts a fresh budget. Recovery is rate-limited, never abandoned, and the
containment that made parking right in the first place is untouched.
Elapsed time, not a timer, so there is nothing to cancel on teardown and no late
fire after dispose.
supersedeDuplicatePaneLeases runs at the top of every reattach pass, and when it
retires anything it flushed synchronously. flushOrThrow fsyncs a multi-MB file
from the Electron main thread — this file already documents (see flushAsync) that
on a stalled network profile mount that syscall is uninterruptible, so the app
stops repainting and no deadline can bound it, because the deadline's own timer
is stuck behind the same block.
The population that hits this is exactly the one the heal exists for: an upgraded
install carrying accumulated duplicates. It now awaits the async durable twin its
neighbours on this path already use. Still "OrThrow", because a retirement that
is not durable must not be believed — the rollback is unchanged.
A remote runtime reaches its pty over a connection that can fail, so a failed
reattach proves no more there than it does over SSH. It keeps replacing in place
only because the card is SSH-scoped, not because its provider is authoritative.
Say that, so the limitation is deliberate rather than implied.
The lease-healing docblock had drifted onto durablyBoundPtyIdForPane, which
neither retires leases nor returns a count, leaving the real healing entry point
undocumented and its neighbour carrying two contradictory descriptions.
The suppression comment claimed to cover "every startup value this transport was
constructed with"; env/envToDelete are constructor values and deliberately stay
outside the set. Nothing behavioural changes here — but a comment that overstates
a boundary is how the next maintainer picks the wrong one.
The unreachable-pane card is SSH-only: a local, daemon or runtime-host pane has
no connection to be unreachable ON. Consolidating that guard into the publisher
made it silent, and four callers paired the now-conditional publish with an
unconditional `return` — so on the deferred-reattach path, which unlike the
direct-SSH one is not nested under `connectionId`, a local pane got no card, no
error and no replacement. Frozen, with a stale binding.
The diversion now reports whether it took ownership of the failure, so a caller
can only stop when something actually handled it. A pane that cannot show the
card falls through to the replace-in-place it had before, which is correct: its
provider is authoritative about its own ptys.
The two direct-SSH sites are inside `if (connectionId)`, so they are unchanged
in behaviour; the return value simply makes the pairing impossible to get wrong
at the next call site.
Round 4 self-check on my own round-3 fix. `suppressSavedStartup` guarded four of
the six values `connect` falls back to — `launchAgent` and
`startupCommandDelivery` still inherited from the transport's constructor. Adding
the guard per field is precisely how those two were missed, and the guarded
expressions had become unreadable.
The saved values are now one object that `suppressSavedStartup` drops wholesale.
A field added later is covered by construction rather than by remembering.
Found by asking the question the review lens was given rather than waiting for
its answer: does the suppression cover EVERY channel, or only the ones I noticed?
It did not.
Correctness round 3. The leaf-keying from round 2 came back clean, twice and
independently. But the renderer produced findings for a third consecutive round,
and they were all one shape: `publishUnreachablePane` is called from seven sites,
each needing the same guards, and a different one was missing at each.
So this stops patching sites and moves the guards into the publisher:
- `disposed` — a late rejection republished a card for a numeric pane id that had
already been reused, giving a fresh pane a phantom card whose actions closed
over a dead session.
- `connectionId` — the deferred catch is not SSH-only. A local/daemon pane could
be shown an SSH ambiguity card it can never clear, and would loop: retry
remounts, reattach rejects, card returns. Its provider is authoritative about
its own ptys, which is exactly why the two branches in handleReattachResult
already had this guard — and why the catch needed it too.
Two more real defects in the banner's own actions:
- "Start a new terminal" passed `null` to suppress the saved agent startup, but
connect FALLS BACK to the startup its transport was constructed with whenever a
per-call field is absent (pty-transport.ts). So the "fresh" shell could resume
the same provider session — the duplicate transcript this pane exists to
prevent, for the third time in this button. `suppressSavedStartup` makes the
suppression explicit; `??` means passing null could never have worked.
- It also cleared both durable bindings BEFORE the spawn, and discarded the
promise. A spawn that resolves null left the pane blank, unbound, and with no
way back to a shell that may still be running. Bindings are now cleared only
once a replacement actually starts, and the card returns if it does not.
- "Try again" voided its boolean; a declined remount left no card and no shell,
strictly worse than the toast it replaced. It now republishes.
The strengthened clause is the point: the old one asserted the ABSENCE of
per-call startup fields on a mocked transport, which passes whether or not the
production fallback fires. It now asserts the explicit suppression, and reddens
when the flag is dropped.
Four fixtures were under-specified — they drive SSH reattach scenarios but never
seeded an SSH repo, so `connectionId` was null and they had been passing without
the pane being SSH at all. Seeded, not weakened.
43,256 pass; the 7 failures are pre-existing on clean main in this environment.
Correctness round 2 confirmed finding. Arbitration ranks leases using the desktop
plane's binding, then handed its losers to a scrub that walked BOTH planes — so
the headless/CLI/mobile plane's binding was deleted for a lease it never got to
vote on. Its owner then has no durable record to reattach that shell by, and can
fall back to recency or orphan a shell that is still running.
`clearSshRemotePtyBindingsForLeases` now takes `arbitratedFrom`. A decision
reached by reading one plane may only mutate that plane. An explicit expiry or
termination is plane-agnostic — the pty is gone for everyone — so those callers
pass nothing and still scrub both, which is what the existing
`markSshRemotePtyLease` oracle pins.
I initially assessed this as not-a-defect, reasoning that local winning IS the
STA-3077 fix. That was about RANKING and did not justify DELETING the other
plane's record; the round-2 verdict was right and I was wrong.
It did also catch a comment of mine that had gone stale — a clause claimed the
other plane was "deliberately left alone" while the code cleared it. The comment
now says what the code does and why.
Mutation: letting arbitration scrub both planes again reddens the new clause.
43,256 pass; the 7 failures are pre-existing on clean main in this environment.
Correctness round 2. This is the reported cardinality growth in its surviving
form, and it is the sharpest finding of the review so far.
Supersession matched sibling leases on `(worktreeId, tabId, leafId)` and bucketed
duplicates under the same key. A lease freezes its tabId when written, and
`detachTerminalPaneToTab` moves a live pane — so after a break-out the pane's
next lease carries the NEW tab and its predecessor carries the old one. The two
never match, the predecessor is never superseded, and the live count grows on
every reconnect. Exactly the reported 2 -> 19 -> 20, for any pane that has been
moved between tabs.
Round 1 fixed the same frozen-tabId mistake at the binding LOOKUP. It did not fix
it here, at the sibling match and the bucket key, which is why the bug survived a
round. Both are now keyed on the leaf — the stable half of pane identity, per
stable-pane-id.ts: the tab half changes on break-out.
Two clauses cover it: a predecessor whose lease names the tab the pane left is
superseded, and the live count stays flat across ten reconnects that each land in
a new tab. Restoring `tabId` to either the match or the key reddens both.
E2E re-run against a real Docker relay after the change: 2 passed. Full suite
43,255 pass; the 7 failures are pre-existing on clean main in this environment.
Correctness review round 1 on #13326: 5 raised, 2 confirmed, both real.
1. Arbitration looked the durable binding up under the lease's FROZEN tabId.
`detachTerminalPaneToTab` moves a live pane and its PTY, and nothing re-keys a
lease, so after a break-out the binding lives under the new tab and the lookup
found nothing. The bound shell then lost to recency and supersession expired
the pane's OWN lease; the follow-on scrub could not clean up either, because
it matches lease.tabId against the layout's tabId. Reconnect skipped the
expired-but-bound PTY and reattached the stale winner onto the pane.
The leaf is the stable half of pane identity, so the lookup now prefers the
named tab and falls back to wherever the leaf actually is.
2. Arbitration read the desktop plane only while the scrub reached into
`ssh:<target>`, so a headless-plane pane was invisible to the ranking and
then lost its live binding to it.
Fixed at the reader, not the scrub: local FIRST, headless plane only as a
fallback. That is NOT the STA-3077 hedge — that bug was preferring
`ssh:<target>`, letting a copy no live writer maintains outvote the real
binding. A fallback consulted only when local is silent gives a headless-owned
pane a vote without ever outranking a live desktop binding.
Proven by mutation: swapping the two back to ssh-first reddens 4 clauses,
including the ten-reconnect cardinality one.
Also closes two fulfilled-result routes to the duplicate agent resume that the
earlier RC2 fix missed — `handleReattachResult` respawned on a result flagged
`sessionExpired` and on a result carrying no pty id. A skeptic refuted both as
pre-existing rather than PR-caused, which is correct on causation, but they are
live routes to the defect this PR claims to fix.
Scoped to SSH panes only. The first attempt diverted every pane and broke three
daemon tests — correctly: a local provider is authoritative about its own ptys,
so "cannot reattach" there is not the ambiguous evidence it is for a relay that
may have been replaced. New clause covers both routes; disabling the diversion
reddens it.
43,253 pass; the 7 failures are pre-existing on clean main in this environment.
Two conflicts:
- .gitignore — both sides added doc negations; kept both.
- orchestration/db.ts — this branch moved `isEquivalentPaneKey` into
shared/stable-pane-id (collapsing a duplicate), while main added
`parseWorkerTerminalPriorOwnerIds` beside the old local copy. Kept the move
and kept main's new helper, rather than resurrecting the duplicate.
43,250 pass. The 7 failures are the same environment-specific pre-existing ones
(osc8 snapshot round-trip, IME resumed-preedit) that fail on clean origin/main
in this environment.
Splits run-idle-cpu-benchmark.mjs into a scale fixture, an in-page timing
probe, and process sampling, and records a measured origin/main baseline so
the agent-status batching slice has an auditable before.
The agent-status write workload is not included: it needs setAgentStatuses,
so it lands with the store slice.
* fix(agents): detect a live OpenCode pane from its native OC | session title
OpenCode publishes `OC | <session>` as its OSC title, which carries no
agent-name token. detectAgentStatusFromTitle gates status on a whole-token
name match, so it returned null and every status consumer read a live
OpenCode pane as a plain shell: no "Send notes to" entry, no title-derived
sidebar row, and a title that the runtime's agent-presence check scored as
neutral. Identity already resolved (getAgentLabel returns OpenCode); only
activity was missing.
Treat the native marker as a live idle agent, placed after the spinner and
glyph checks so the decorated frames pinned by #8940 keep their status, and
accept it in the send-readiness gate the way Claude's U+2733 prefix is
accepted -- only a running OpenCode TUI ever publishes it.
* fix(agents): require spaced `OC | ` marker for native OpenCode detection
Unspaced pipes like `OC|Build` match other tools and would mistakenly
route non-OpenCode panes as send targets. Enforce literal ` | ` as
OpenCode emits it. Also clarify that only spinner decorations carry
working status, not keywords in the session summary.
* fix(agents): require OpenCode foreground process to validate native mark
OpenCode's native `OC | ` title marker now requires an active OpenCode process
to authorize agent sends, preventing false detection when the marker is left on
shell prompts. Extends wrapper prefix matching (ssh, tmux, etc.) and spinner
glyph support. Adds permission-prompt blocking signals for guarded writes.
The migration moved legacy `ssh:<target>` pane bindings into `local` and cleared
them, on the theory that the ssh partition was a stale spill of the desktop
plane's state. Investigation of both hypotheses the team raised disproved that:
- NOT cross-version compat. The introducing commit says it is for CONCURRENT
multi-host. Nothing about the partition crosses the wire (zero references under
src/main/runtime/rpc/), and the payload that does cross the SSH boundary —
RemoteWorkspaceSnapshot — is projected from `local`. The only downgrade-compat
comment protects `local`, the other direction.
- NOT multi-client. PersistedState is one file on one machine; phones and CLI are
RPC clients into that same process. Orca's real per-client state is
`mobileClientTabSelectionsByDeviceId`, 13 lines above in the same struct, and
it carries selections only — never a ptyId.
What it actually is: the headless/CLI/mobile plane's OWN home, written and read
deliberately across several tickets (STA-3463, STA-3465), with tests that assert
that partition by name. So the fold was not tidying a spill — it was erasing
another plane's live state. Measured symptom: a split SSH tab would disappear
from mobile while its shell kept running.
The desktop plane's fix never needed it. Supersession multiplied panes because
`durablyBoundPtyIdForPane` hedged into the other plane's copy; reading `local`
alone is the fix, and it stands without any migration.
Deleting rather than redesigning, because the redesign had no target: five review
rounds each found a defect in that function, three of them inside the previous
round's fix, and every one was a cell of a merge matrix that only existed to
serve a premise that was false.
The `boundPtyIdsAcrossPartitions` clause is INVERTED, not dropped. It required
the two partitions to AGREE after load — which encoded the false premise, and is
what made a migration look necessary. It now asserts the narrower, stronger
property: what the desktop plane resolves follows `local` alone, whatever the
other plane holds.
Also proven, and the reason unification was NOT attempted: worktreeId is
`<repoId>::<path>` where repoId is a randomUUID minted client-side at repo add
(orca-runtime.ts:18722), so two servers cannot collide on one. Host scoping was
not protecting against that here — but the two planes' opposite choices are each
deliberate and each test-pinned, so choosing a winner is an architecture call,
not a cleanup.
Net production: -75 lines.
Three conflicts, all resolved keeping both sides:
- persistence.ts — both sides added a field to persistPtyBinding's options.
Kept `mayCreate` (ours) and `expectedSourceBinding` (main's).
- ipc/pty.ts — main added an `expectedSourceBinding` CAS and a
`terminal_split_source_not_found` throw to the exact block our `bindPaneShell`
producer replaced. Threaded `expectedSourceBinding` THROUGH the producer rather
than dropping it, and kept main's refusal throw on `bound === false`. Dropping
it would have silently disarmed a CAS main just added.
- pty-connection.test.ts — main added `startupCommandDelivery: 'shell-ready'` to
a resume assertion this branch deletes outright (the resume no longer happens).
Took ours; main's addition is moot in an inverted clause.
Also repairs a rename/rename divergence unrelated to STA-3077: both sides deleted
a different half of a duplicated xterm-bypass fixture, so the merge deleted both.
Restored main's `xterm-bypass-event-fixture.ts` and repointed three test imports
at it, adopting main's convention rather than this branch's older move.
Verified after merge: 43,179 tests pass. The 7 failures (osc8 snapshot
round-trip, IME resumed-preedit) are PRE-EXISTING on clean origin/main — checked
against a baseline worktree, not assumed. Typecheck clean on node and web.
promptCacheTtlMs was a third store subscription for a field the card
already reads via foundation.settings; derive it instead.
Does NOT bundle the 26 foundation selectors as originally planned.
Measured on this store with React (150 cards, 400 unrelated writes,
26 keys): 26 separate useAppStore hooks 100.7ms; one useShallow bundle
402.5ms (4.0x worse); one bundle with a non-allocating keyed compare
141.5ms (1.4x worse). zustand v5 shallow() rebuilds two Maps from
Object.entries per compare, and a bundle must still build the whole
projection every notification, so collapsing cheap selectors only
trades away useSyncExternalStore dispatches that are cheaper than the
object it allocates. Listener count would have improved 26 -> 1 while
the hot path got slower.
docs/design/agent-status-over-ssh.md was cited from ~10 source files but
does not exist in the repo. Replace each pointer with the invariant the
code actually relies on so the knowledge survives without the doc.
Renderer-side citations (useIpcEvents.ts, agent-status-types.ts) are left
for the concurrent batching change that owns those files.

* fix(terminal): carry kitty flags through Preview snapshots and pair rele
Preview was omitting the live kitty mirror from the IME bridge and dropping kitty flags from snapshots, so every commit was evaluated at flags 0. A TUI that negotiated bit-3 (report_all_keys_as_escape_codes) would receive the legacy raw text it declined.
Now the snapshot carries proven kitty flags beside their sequence boundary, the forwarder reads flags once per commit, and bit-1 (report_event_types) commits are paired with exactly one release regardless of keyup/insertText ordering. Snapshot authorities expose only the active screen's proven flags, so an old host's absent field stays unknown rather than downgraded to a manufactured zero.
* fix(terminal): sync kitty flags and IME releases across snapshots
* trim wordinesss
* fix(terminal): settle owed IME release before fresh same-key press
When a keyup is lost and the same key is pressed again, settle the stale
record's owed release instead of discarding it — this maintains correct
IME state during recovery. Also refine Kitty flag propagation to only
carry proven baselines across snapshots, and tighten related comments.
* fix(terminal): gate kitty flags on sequence boundaries
- Remote snapshots only include flags when seq is present
- Daemon uses parsed flags value when defined
- Ensures correct flag ordering in snapshot replay
