* Zellij to Tmux and some other fixes. (#404)
* feat(runtime): add tmux adapter package
Adds backend/internal/adapters/runtime/tmux implementing ports.Runtime via
the tmux CLI. Drop-in replacement for the zellij adapter on Darwin/Linux.
Key design points:
- Handle is a plain session id string (no pane-id split needed for tmux).
- Exact-match session targeting via = prefix for kill-session and has-session.
- Keep-alive shell appended to launch command so sessions survive agent exit.
- send-keys -l chunked for literal text delivery (no key-name interpretation).
- IsAlive distinguishes definitive-dead (missing/no-server output) from probe
errors so the reaper never kills a session on a transient tmux failure.
- 34 tests pass: 32 unit tests via fakeRunner seam, 2 integration tests on
real tmux 3.6b (TestRuntimeIntegration, TestRuntimeIntegrationExactSessionParsing).

* fix(tmux): address four code-review findings in tmux runtime adapter
- Remove em dash from tmux_test.go:462 (project hard rule); replace with semicolon
- Derive integration test session IDs from t.Name() so concurrent runs do not collide on the same tmux session
- Remove dead scaffolding variables (r/fr, r2/fr2) in TestCreateDestroysAndReturnsErrorWhenNotAlive
- Quote \${SHELL:-/bin/sh} in buildLaunchCommand and update all asserting tests

* feat(runtime): wire tmux on Darwin/Linux via runtimeselect, keep zellij on Windows
- New package runtimeselect: Runtime union interface (ports.Runtime +
SendMessage/GetOutput/AttachCommand) with compile-time assertions for
both adapters. New(log) returns tmux on non-Windows, zellij on Windows
(replicating the old daemon socket-dir setup).
- daemon.go: replace zellij-specific socket-dir block with
runtimeselect.New(log); update comment to be runtime-neutral.
- lifecycle_wiring.go: startSession param changed from *zellij.Runtime
to runtimeselect.Runtime.
- cli/doctor.go: runtime-aware checkTerminalRuntime (tmux on Darwin/Linux,
zellij on Windows); added checkTmux.
- cli/spawn.go: attach hint prints tmux attach -t <name> on non-Windows,
keeps zellij attach hint on Windows.
- wiring_test.go: startSession test uses runtimeselect.New(nil); zellij
direct tests retained for zellij-specific coverage.
- doctor_test.go: replaced three zellij tool tests with tmux equivalents.

* chore: tidy runtime-neutral comments and doctor import grouping
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* refactor(tmux): drop unused runner.Start seam
tmux creates sessions detached via new-session -d, so the Start method
(carried over from the zellij runner shape, where it backs the Windows
fire-and-forget spawn) is never called. Remove it from the interface and
its implementations to shrink the seam.

* feat(conpty): add protocol codec and output ring buffer (pure Go, OS-agnostic)
Ports the ConPTY named-pipe binary framing protocol and rolling output
buffer from pty-host.ts to Go. Implements EncodeMessage, MessageParser
(handles arbitrary chunk boundaries, payload copy guarantee), and Ring
(MaxOutputLines=1000, ANSI-safe, concurrent Append+Snapshot). All 15
unit tests pass on Darwin; GOOS=windows build is also clean.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* test(conpty): harden copy-safety and add concurrent ring test
Strengthen TestParserPayloadIsCopy to catch internal-buffer aliasing:
feed frame1, capture its payload, feed frame2 of the same length so the
parser's buffer overwrites the frame1 region, then assert frame1's bytes
are unchanged. The prior test only mutated the input slice post-Feed and
did not exercise the real aliasing risk.
Add TestRingConcurrent: 10 writer goroutines (Append) and 10 reader
goroutines (Snapshot + Tail) running concurrently with a WaitGroup. The
test is meaningful only under the race detector and catches any missing
mu coverage on Ring's exported methods.

* feat(ptyregistry): port Windows pty-host sideband registry to Go
Adds package ptyregistry under backend/internal/adapters/runtime/conpty/ptyregistry.
Ports windows-pty-registry.ts: defensive read, atomic temp+rename write,
delete-on-empty, register-replaces-same-ID, and auto-pruning List.
PID liveness isolated behind build tags (syscall.Kill on Unix,
OpenProcess on Windows). 10 tests all green on Darwin.

* chore(sdd): phase B briefs and progress for B1-B3
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* feat(conpty): add pty-host serve engine with loopback TCP transport (B3)
Ports pty-host.ts behavior to Go: ptyConn interface seam, Serve engine
with ring replay, fan-out broadcast, MSG_* handlers, PTY-exit keep-alive,
and graceful shutdown (ConPTY dispose first, 50ms grace, then clients and
listener). Real conptyConn is Windows-only via build tag; non-Windows stub
keeps the package importable on Darwin/Linux. Tests use a fake ptyConn
with real loopback sockets and the B1 MessageParser, passing with -race.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* fix(conpty): deliver scrollback snapshot and register client atomically
Review of Task B3 found one Important bug and two minors.
Important: in handleConn the ring Snapshot and the client registration
ran under two separate h.mu acquisitions. A PTY chunk arriving in that
gap was in neither the snapshot nor that client's broadcast, so it was
silently dropped (a hole in the client's stream). Now take the snapshot,
write it to the conn, and add the conn to the clients set all under a
single h.mu hold; broadcast also takes h.mu so it cannot interleave.
Added TestScrollbackLiveOrdering_NoDrop, which emits a contiguous
numbered stream while a client connects and asserts the client's stream
has no internal gap. It reliably fails against the old two-step code and
passes under -race -count=20.
Minor (faithfulness): conptyConn.Close() now also best-effort
Process.Kill() (nil-guarded) so a child that ignores ConPTY EOF still
exits and Done() fires, mirroring pty.kill() in pty-host.ts.
Minor (simplify): use os.Environ() instead of
exec.Command(shellCmd).Environ() for the child env.

* chore(sdd): B4 brief
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* feat(conpty): add runtime adapter with loopback pty-client and session management (B4)
Implements the conpty Runtime adapter: injectable spawn seam, loopback
TCP client helpers (SendMessage/GetOutput/IsAlive/Kill), and Runtime
methods (Create/Destroy/IsAlive/SendMessage/GetOutput). Session resolution
uses an in-memory map with B2 registry fallback for daemon-restart
recovery. Windows-only detached spawn in spawn_windows.go; stub errors
on other OSes. All adapter methods are unit-tested on Darwin against an
in-process B3 Serve and fakePTY. 48 tests pass, all three GOOS builds
succeed, vet clean.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* fix(conpty): split IsAlive dead-vs-transient for reaper safety
clientIsAlive collapsed every probe failure (dial timeout, read-deadline
expiry, write error, connection-refused) to false, which the reaper turns
into ProbeDead and the LCM can promote to a permanent reap. A single
transient 2s loopback timeout would spuriously kill a live idle session.
Now clientIsAlive returns (alive bool, transientErr error): a refused dial
is definitively gone (false, nil); a timeout or any connected-then-failed
I/O error is transient (false, err) so the reaper records ProbeFailed and
retries. Wire IsAlive to propagate it. Add regression test covering both
the refused-is-gone and timeout-is-transient paths.

* chore(sdd): B5 brief + ledger
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* feat(terminal): stream-based Attach for tmux/zellij/conpty
Evolve the terminal layer from argv-based attach (PTYSource.AttachCommand
+ injected spawnFunc) to stream-based attach (Source embedding
ports.Attacher). tmux/zellij keep spawning their attach CLI on a local
PTY via the new shared ptyexec.Spawn; conpty attaches by dialing its
loopback pty-host directly with a loopbackStream over the B1 framing
protocol. Reattach/backoff/size/SIGWINCH/detach semantics are unchanged.
- ports: add Stream + Attacher.
- ptyexec: new shared package holding the creack/pty (unix) and ConPTY
(windows) spawn, moved verbatim from terminal with its tests.
- terminal: PTYSource -> Source, drop spawnFunc/WithSpawn, run loop calls
src.Attach and uses ports.Stream.
- tmux/zellij: add Attach (argv via ptyexec.Spawn); conpty: add Attach
(loopbackStream); ports.Attacher assertions on all three.
- runtimeselect: union embeds ports.Attacher in place of AttachCommand.
- tests migrated; new conpty attach_test against in-process Serve+fakePTY.

* feat(runtime): select conpty on Windows, register pty-host subcommand, delete zellij
- runtimeselect.New: Windows branch now returns conpty.New(conpty.Options{}) instead
of zellij; compile-time assertion updated to conpty.Runtime.
- cli/ptyhost.go: new hidden "ao pty-host" subcommand (DisableFlagParsing so agent
shell args with leading dashes survive); calls conpty.RunHost and exits with its code.
- cli/root.go: wires newPtyHostCommand alongside newLaunchCommand.
- cli/doctor.go: Windows terminal-runtime check replaced with a static ConPTY
built-in pass; zellij import and checkZellij function removed.
- cli/spawn.go: Windows attach hint updated to dashboard message (ConPTY has no
CLI attach); zellij import removed.
- daemon/lifecycle_wiring.go: stale zellij comment updated to tmux/conpty.
- daemon/wiring_test.go: zellij import and TestDaemonZellijSocketDir test removed;
TestWiring_StartLifecycleThreadsMessengerIntoLCM now uses tmux.New.
- terminal/attachment_integration_test.go: re-pointed at real tmux
(TestAttachmentStreamsRealTmuxPane + TestAttachmentReattachAdoptsNewSize);
sessions cleaned up in t.Cleanup.
- internal/adapters/runtime/zellij: deleted entirely.
All three GOOS builds pass; go test -race ./... 1607 passed; go vet clean;
grep -rn "runtime/zellij" returns nothing.

* fix(daemon): default TERM so Finder-launched tmux attach works
A Finder/Dock launch starts the supervisor under launchd with no
controlling tty, so TERM is unset. The daemon inherits that, and its
tmux attach client (spawned with env=nil, inheriting the daemon env)
dies immediately with "open terminal failed: terminal does not support
clear" — the orchestrator terminal pane never opens.
Seed TERM=xterm-256color (what the renderer's xterm.js emulates) as the
base of buildDaemonEnv, the same place PATH is reconstructed for the same
class of "Finder launch lacks a terminal's env" bug. A real TERM from the
shell/process env still wins.

* docs(lifecycle): plan for save-on-close/restore-on-open sessions
Captures the intended daemon lifecycle: on shutdown save every running
session (worker and orchestrator) plus its gitignore-respecting uncommitted
work to refs/ao/preserved/<id>, then force-remove worktrees; on boot recreate
worktrees, replay the preserved work, and restore all sessions. Reuses
existing SQLite state, session_worktrees.preserved_ref, manager.Restore, and
the /shutdown endpoint (no new file, migration, or route).
Also gitignore the built daemon binary copied into frontend/daemon/.

* chore(frontend): sync regenerated pnpm-lock and routeTree
Working-tree regeneration of the pnpm lockfile and TanStack Router generated
route tree. No hand edits; generated output only.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* feat(workspace): add ForceDestroy for shutdown-path worktree removal
Adds ForceDestroy(ctx, info) to ports.Workspace and the gitworktree
adapter. It runs `git worktree remove --force`, then prune, then
os.RemoveAll as a backstop. A new worktreeForceRemoveArgs builder in
commands.go emits --force; the existing worktreeRemoveArgs is untouched
so Destroy still refuses dirty worktrees via ErrWorkspaceDirty.
TDD: test first creates a dirty worktree, confirms Destroy refuses with
ErrWorkspaceDirty, then confirms ForceDestroy succeeds and the path is
gone and deregistered. All 1609 backend tests pass.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* feat(workspace): add StashUncommitted and ApplyPreserved for session lifecycle
Implements the correctness-critical save-on-close / restore-on-open pair
in the gitworktree adapter:
- StashUncommitted: captures uncommitted work (tracked edits and new
non-ignored files) via a temp GIT_INDEX_FILE into a real commit stored
at refs/ao/preserved/<session-id>. Never touches the real index or
stash stack. Returns empty string for clean worktrees. Logs the count
of .gitignore-skipped paths.
- ApplyPreserved: replays the preserve commit onto a freshly re-added
worktree via "git checkout <SHA> -- .". Deletes the ref on clean
success; keeps it and returns ErrPreservedConflict (wrapped) on
content conflicts.
- Adds both methods to ports.Workspace interface and stubs them in
integration and session_manager test doubles.
TDD: wrote two failing tests first (RED confirmed via build failure on
undefined methods), then implemented to GREEN. All 39 adapter tests pass.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* fix(workspace): replace path-checkout with cherry-pick in ApplyPreserved
git checkout <sha> -- . is a path-checkout that always exits 0 for
content divergence, making ErrPreservedConflict unreachable. Replace
with git cherry-pick --no-commit which performs a true three-way merge,
leaves textual conflict markers on conflict, and exits non-zero so the
sentinel is correctly returned. Conflict detection now uses exit code
only (locale-independent). Add TestWorkspaceIntegrationApplyPreservedConflict
to assert: error is ErrPreservedConflict, preserve ref is kept, conflict
markers appear in the file. All 40 tests pass.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* feat(session-manager): add SaveAndTeardownAll and RestoreAll for shutdown lifecycle
Implements Task 3: capture-then-destroy on shutdown and restore-all on startup.
- Adds ErrPreservedConflict to ports as a named sentinel; gitworktree aliases it
(following the same pattern as ErrBranchCheckedOutElsewhere).
- Extends the Store interface with UpsertSessionWorktree and ListSessionWorktrees
so the session manager can write the shutdown-saved marker and read it back.
- SaveAndTeardownAll: for every live session with a workspace path, stash
uncommitted work, write the session_worktrees row (DB commit before worktree
removal, crash-safety invariant), mark terminated, destroy runtime, force-remove
the worktree. Best-effort per session; no kind filter.
- RestoreAll: for every terminated session that has a session_worktrees row (the
marker written by SaveAndTeardownAll), re-create the worktree, apply any
preserved ref (conflict logs and continues), then relaunch via the existing
single-session Restore. Sessions killed by the user before shutdown (no row)
are skipped. Best-effort per session; no kind filter.
- TDD: 9 new tests (RED confirmed via build failure, GREEN confirmed 63 pass).
Full suite: 1621 tests across 77 packages.

* fix(terminal): enable tmux mouse scroll and fix link clicking
On macOS the runtime is tmux, but two mouse interactions were broken in
the embedded terminal while copy/paste kept working:
- Scroll: the renderer drives scrolling by writing SGR mouse-wheel
reports into the pane (the zellij `--mouse-mode true` model), but tmux
ignores those reports unless mouse mode is on. Create only set `status
off`, never `mouse on`, so wheel scrolling silently no-opped. Enable
`set-option -t <id> mouse on`, mirroring the existing status-off step.
- Link clicking: the default WebLinksAddon handler calls window.open()
with an empty URL and then assigns location.href. Electron's
setWindowOpenHandler denies every window.open and only forwards the URL
passed to it, so the empty open is dropped and clicks no-op. Pass the
matched URL to window.open directly so the main process routes it to
shell.openExternal (the OS browser).

* test(session-manager): assert UpsertSessionWorktree precedes ForceDestroy
Add a shared ordered call log (sharedLog *[]string) to both fakeStore
and fakeWorkspace. TestSaveAndTeardownAll_CaptureOrderAndMarker now
wires both fakes to the same slice and asserts upsertIdx < forceIdx,
enforcing the crash-safety invariant that the DB write is committed
before the worktree is force-destroyed.

* feat(daemon): wire RestoreAll/SaveAndTeardownAll into boot/shutdown sequence
Exposes session manager through a minimal sessionLifecycle interface
(RestoreAll, SaveAndTeardownAll) returned from startSession, then calls
RestoreAll (best-effort) before srv.Run and SaveAndTeardownAll with a
fresh 30s-bounded context after srv.Run returns. Both SIGTERM and POST
/shutdown funnel through srv.Run returning, so the single save call site
covers both paths.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* test(daemon): fix seam-test tautology and lifecycle variable shadow
Finding 1: dispatch both sessionLifecycle methods through an interface
variable (var sl sessionLifecycle = fake) so the runtime body exercises
interface dispatch, not just direct struct method calls.
Finding 2: rename local variable 'lifecycle' to 'lc' in
TestWiring_StartSessionBuildsSessionService to remove the shadow of the
imported lifecycle package.

* feat(frontend): call POST /shutdown before killing daemon on quit
In before-quit, POST /shutdown (8s AbortSignal.timeout) so the daemon
saves sessions gracefully before the SIGTERM kill. Adds a re-entrancy
guard (quitting flag) so a concurrent app.quit() cannot double-preventDefault.
Falls back to killDaemon on fetch failure or timeout: quit is never blocked.
Keeps the process.on('exit') SIGTERM fallback intact.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* fix(storage): guard session_worktrees.state against empty-string CHECK violation; add ponytail comments
The save path (saveAndTeardownOne) never sets domain.SessionWorktreeRecord.State,
so it arrives at UpsertSessionWorktree as "". The generated upsert includes state
in the INSERT column list, so the DB default ('active') is never applied and the
CHECK constraint (state IN ('active', ...)) would fire at the first real shutdown.
Fix: default to 'active' in the store adapter when row.State is "". No schema
change, no migration, no gen edit.
Also add ponytail: comments on the State field (domain type), the write path, and
the read path, documenting that state is unused multi-repo scaffolding and that the
upgrade path is to wire a real value when multi-repo worktree lifecycle states ship.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* test(storage): add real-SQLite test for empty-State guard in UpsertSessionWorktree
Adds TestUpsertSessionWorktreeEmptyStateDefaultsToActive to the store
test file. It inserts a SessionWorktreeRecord with State at zero value
"" via UpsertSessionWorktree against a real SQLite DB, then reads the
row back and asserts State == "active". This directly exercises the
guard added in the prior commit and would fail if the guard were
removed (the CHECK constraint rejects ""). Mirrors the helpers and
setup pattern of TestSessionWorktreesRoundTrip exactly.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* fix(comments): correct shutdown-mechanism and task-ref inaccuracies
Fix 1: daemon.go comment near SaveAndTeardownAll now correctly states
that POST /shutdown closes the shutdownRequested channel (not cancel ctx).
Also tighten the RestoreAll comment to remove the inaccurate claim.
Fix 2: remove "Task 2's" phrasing from ForceDestroy ponytail comment in
workspace.go; condition still references StashUncommitted by name.
Fix 3: add note in main.ts that the 8s fetch timeout is shorter than the
daemon's 30s save bound, so a SIGTERM after fetch abort does not cut the
in-flight save short.

* docs(spec): graceful restore + post-failure orchestrator recreate
Fix the opaque 500 when restoring an un-resumable session (typed 409
SESSION_NOT_RESUMABLE), and add a post-failure popup that offers to recreate a
fresh orchestrator on the same branch (cleaning the worktree, preserving
committed history). Orchestrators only; recreate fires only after a restore
attempt confirms the session cannot be resumed.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* docs(plan): restore-recreate orchestrator; reuse existing /orchestrators clean=true
Planning discovery: the recreate capability already ships via POST /orchestrators
(clean=true), which kills the dead orchestrator and re-spawns on the canonical
branch (addWorktree reattaches an existing branch). So the feature collapses to a
typed-error fix plus a frontend popup. Spec updated to match.

* fix(ci): gofmt/goimports, golangci-lint hygiene, and Windows-aware doctor tests
Formatting: ran gofmt and goimports (with local-prefixes) on the 8 listed
files plus ptyexec/spawn_unix.go which the linter also flagged.
Lint (25 issues fixed):
- gosec G115: EncodeMessage now returns ([]byte, error) with an explicit
bounds check before the int->uint32 conversion; all callers updated.
- govet nilness: removed dead `if lastErr == nil` branch in clientIsAlive;
lastErr is provably non-nil at that point (real bug).
- nilerr: extracted runAcceptLoop helper so Accept-error-on-close is not
flagged; listener close is normal shutdown, not a caller error.
- staticcheck SA4010: removed dead `full = append(...)` loop in host_test.
- revive var-declaration: `var prev int = -1` -> `prev := -1`.
- revive redefines-builtin-id: deleted local `min` helper; builtin covers it.
- unparam (2): dropped always-nil env return from attachCommand; dropped
unused shellPath param from buildLaunchCommand; updated callers.
- errcheck (8): deferred Close/Remove calls wrapped in func(){_ = ...}();
type assertion in host_main.go uses ok-form; fmt.Fprintf to stdout uses
_, _ = pattern; workspace.go tmpIdx.Close() uses _ =.
- gocritic nestingReduce: inverted if+continue in runtime.go resolve loop.
Windows E2E: skip TestDoctorChecksTmuxVersion,
TestDoctorChecksTmuxVersionFailsOnError, TestDoctorWarnsWhenTmuxMissing on
windows (ao doctor emits a conpty check there, not tmux).
Verified: gofmt -l . clean, golangci-lint 0 issues, go build ok,
go test -race 1624/1624 pass.

* test(ci): set git identity in worktree clone fixture; loosen tmux reattach timeouts
The preserve round-trip/conflict tests commit inside a worktree of the cloned
repo, which had no git identity; CI runners cannot auto-derive one, failing with
"empty ident name". Set user.email/user.name on the clone in setupOriginClone so
its worktrees inherit it.
The tmux reattach test drives a real shell and parses stty output, which is slow
under -race on CI; raise its echo-write and SIZE-output waits.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* test(terminal): resend size probe on tmux reattach until the shell answers
Bumping timeouts was the wrong fix: a 30s wait still failed, so the probe output
deterministically never appeared, not slowness. onOpen signals the stream accepts
input, not that the reattached sh -i is at a prompt, so the first echo keystroke
can be dropped. Resend the probe each poll until SIZE output lands, and on timeout
dump the captured pane buffer so a remaining failure is self-explaining.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* test(terminal): set TERM for real-tmux attach tests so they run in CI
Root cause (from the buffer dump the prior commit added): with TERM unset on CI
runners, tmux refuses to attach a client and prints "open terminal failed:
terminal does not support clear", so the pane never runs the size probe. The
daemon defaults TERM in production; the tests bypass it. Set TERM=xterm-256color
in both real-tmux tests. Reproduced locally with `env -u TERM` (fails the same
way) and verified the fix passes under it.

* docs(spec): crash-proof session reconcile design
Boot-time reconcile makes live tmux + worktree state match the DB on every
daemon start, so a SIGKILL/crash/force-quit that skips SaveAndTeardownAll no
longer leaks an orphaned daemon, tmux sessions, or worktrees. Adopt
crash-surviving tmux sessions, preserve-and-terminate dead ones, reap
in-namespace orphans, and add a frontend kill+replace branch for a wedged
orphan daemon.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* docs(spec): simplify reconcile to per-session IsAlive, drop ListSessions
Every leak in the incident maps to a DB row, so orphan-reap is a per-session
IsAlive+Destroy over terminated rows; no runtime enumeration, no ports/conpty/
runtimeselect changes. Reaping a tmux session with no DB row is deferred (YAGNI).

* feat(frontend): kill+replace a wedged orphan daemon on launch
When both inspectExistingDaemon and resolveDaemonFromPort return null but
a process still holds the daemon port (a crashed/orphaned daemon), spawning
a new Go child would collide on the port and exit 1. Detect this case, SIGTERM
the holder (via the run-file PID, falling back to the probe PID), poll until the
port is free (up to 8s), clear the stale run-file, then proceed to spawn fresh.
The healthy-daemon reuse path is unchanged.

* fix(frontend): fire orphan-daemon takeover when a holder actually exists
Replace planDaemonTakeover (inverted logic: ran kill block only when probe

true when a real holder exists: non-null probe (rejected responder) OR a
run-file PID that is still alive (hung holder). Update main.ts call site to
compute PID liveness before gating the kill block. Update tests to cover all
three distinct outcomes non-vacuously.

* fix(session): restore promptless orchestrators and crash-orphaned sessions
The orchestrator was abandoned on every app open: a fresh orchestrator
spawned each launch and the prior conversation appeared lost (it was not;
the transcript stays in ~/.claude, resumable by the deterministic
--session-id AO pins). Two defects combined:
1. Restore's guard rejected any session with no agentSessionId AND no
prompt as ErrNotResumable. But Claude resumes via a deterministic
session id regardless of those fields, so promptless orchestrators
were perfectly resumable yet always rejected. Workers slipped through
only because they carry a prompt. Move the resumability decision to the
adapter: restoreArgv returns ErrNotResumable only when GetRestoreCommand
reports it cannot resume AND there is no prompt to fresh-launch from.
2. reconcileLive marked a crash-orphaned (dead-runtime) session terminated
without a restore marker, so RestoreAll skipped it and it stayed dead.
It now saves-and-tears-down to the same end state a graceful shutdown
produces (capture work, write the session_worktrees marker, terminate,
remove the worktree), so RestoreAll relaunches it on the same boot,
resuming history. Crash recovery now matches graceful restart. If work
capture fails it terminates without a marker rather than risk losing
un-preserved work.
Tests: promptless orchestrator restores via adapter resume; promptless
session with a non-resuming adapter still returns ErrNotResumable;
reconcileLive writes the marker + tears down the worktree. Full backend
suite green (1632), gofmt/vet clean.

* chore: format with prettier [skip ci]
* docs: scrub stale zellij references after tmux/conpty migration (#409)
PR #404 migrated the runtime adapter from Zellij to tmux (Darwin/Linux)
plus conpty (Windows), selected via runtimeselect, but ~30 stale zellij
references lingered in comments and docs describing zellij as the current
runtime. This is a comments/docs-only cleanup with no behavioral change:
comments now say tmux (or tmux/conpty when both platforms are relevant),
terminal/doc.go and docs/backend-code-structure.md are rewritten to
reflect the tmux + conpty + runtimeselect attach model, and the daemon
environment, STATUS, stack, architecture, and CLI docs are updated.
Also gitignore the local .codegraph/ and .cursor/ tooling dirs.

* fix(daemon): self-heal a stale run-file instead of refusing to start
On Windows the desktop supervisor can only TerminateProcess the daemon
(no POSIX signal reaches a detached child), so the daemon's graceful
shutdown never runs and ~/.ao/running.json is never removed. The leaked
file survives into the next launch, and because Windows reuses PIDs
aggressively the recorded PID usually belongs to an unrelated process.
The startup pre-flight trusted PID liveness alone (runfile.CheckStale ->
processalive.Alive), so it concluded a daemon was "already running" and
exited with "refusing to start" on every restart. A dead daemon then
makes the renderer's loopback REST calls (e.g. Spawn Orchestrator) fail
silently.
Verify the recorded port is actually served by an AO daemon with the
recorded PID (a /healthz probe matching service + pid, the same ground
truth inspectDaemon already uses) before refusing. A run-file left by a
crashed, hard-killed, or reused-PID predecessor is treated as stale and
overwritten, so startup is robust to a leaked run-file from any cause.
Fixes#256
* fix(release): build the desktop daemon natively on each target OS
build-daemon.mjs compiles the bundled `ao` daemon with the build host's
GOOS and names it off the host platform (ao.exe only when the builder is
Windows). The release workflow ran only on macos-latest, so a Windows
package would ship a macOS binary named `ao` with no `ao.exe`, and the
app could not launch a valid Windows daemon ("This program cannot be run
in DOS mode" / binary not found).
Run the release as a per-OS matrix (macOS + Windows) so host == target
and each installer bundles a daemon compiled for its own platform, and
pin the Go toolchain with setup-go since build-daemon needs it on every
runner.
Fixes#235
* feat(terminal): Windows ConPTY support for /mux attach
Replaces the Windows stub in internal/terminal/pty_windows.go with a real ConPTY implementation backed by github.com/aymanbagabas/go-pty, so the daemon's /mux attach can stream a live terminal to the renderer on Windows.
PTYSource.AttachCommand now returns (argv, env, err). On Windows the zellij attach is spawned directly (no powershell.exe wrapper) — wrapping ConPTY startup around a shell surfaces as modal application-error dialogs — and the per-session ZELLIJ_SOCKET_DIR is delivered via the spawn's CreateProcess env block instead of an 'env -u NO_COLOR' shim. Unix continues to use the env-shim wrapper and returns nil env.
Adds go-pty v0.2.3 (+ bumps golang.org/x/sys to v0.44.0 transitively). Updates the in-process test fakes (terminal/fakes_test.go, httpd/terminal_mux_test.go) for the new signature.
* feat(zellij): discover zellij binary on Windows and raise command timeout
Defaults the zellij binary to whatever exec.LookPath finds first (preferring zellij.exe on Windows), falling back to LOCALAPPDATA\Programs\zellij\zellij.exe and ProgramFiles{,(x86)}\{zellij,Zellij}\zellij.exe so a fresh-installed Windows user gets a working runtime without setting Options.Binary.
Raises the per-command timeout from 5s to 30s on Windows: the first zellij invocation after install routinely takes longer than 5s on Windows due to filesystem/AV warmup, which was causing benign DeadlineExceeded failures during session create.
* feat(zellij,cli): Windows agent launcher trampoline for codex argv
On Windows, zellij's KDL `args` quoting cannot round-trip codex's --config key=value flags (or any argv with embedded quotes), and shell-wrapping the agent in powershell/cmd quoting is equally unsound. This adds a small launch trampoline so zellij runs a known-fixed argv and the real argv is delivered out-of-band.
How it works on Windows:
1. zellij.Runtime.writeLayout persists cfg.Argv to a temp JSON spec via the new agentlaunch package (AO_LAUNCH_SPEC env var points at the file).
2. The KDL layout runs the trampoline as `<ao.exe> launch` (windowsLaunchArgv); PATH is augmented so the trampoline resolves.
3. The new hidden `ao launch` subcommand reads the spec, deletes the temp file, and execs the real agent with cfg.Argv inside cfg.WorkspacePath.
Also adds:
- runner.Start fire-and-forget path (process_windows.go uses powershell.exe -EncodedCommand + Start-Process -WindowStyle Hidden with CREATE_NEW_CONSOLE so the daemon is not blocked on zellij's --create-background settling).
- powerShellEncodedCommand helper and switch from -Command to -EncodedCommand for the existing powershell shellLaunchSpec (avoids brittle KDL→PowerShell quoting round-trips).
Unix is unchanged: writeLayout passes cfg.Env straight through, createSession stays synchronous via runner.Run, and process_other.go is a stub that returns an error if anyone calls into the background path.
* feat(codex): Windows binary resolution, terminal compat flags, TOML literal strings
Three Windows-targeted refinements to the codex agent plugin so a default Windows install lands in a working state:
1. ResolveCodexBinary now follows .cmd/.ps1 shims to the underlying codex.exe (resolveNativeWindowsCodex + windowsNativeCodexCandidatesForShim). The npm-distributed codex shim cannot be exec'd directly under ConPTY without a shell wrapper; jumping straight to the .exe avoids that wrapper.
2. appendTerminalCompatibilityFlags adds Windows-specific args (e.g. --no-alt-screen) so codex's TUI renders correctly inside zellij's pane without the alternate-screen buffer churn that breaks ConPTY redraws.
3. hooks.go gains codexTOMLLiteralString / codexTOMLConfigString / containsTOMLControl so paths and other values with backslashes and quotes round-trip through codex's --config TOML parser using literal strings ('...') when basic strings would require unsafe escaping.
* fix(lint): paramTypeCombine in pty_unix.go, revive doc comments in agentlaunch, codex test quotes
* fix: stabilize windows zellij sessions

* refactor(terminal): per-client zellij attach replaces shared PTY + replay ring
Each WebSocket client that opens a pane now gets its own `zellij attach`
PTY (attachment.go) instead of sharing one PTY whose output was replayed
from a bounded byte ring. Zellij answers every fresh attach with its full
init handshake (alt screen, SGR mouse tracking, bracketed paste) and a
faithful repaint — the ring replay lost exactly that handshake, leaving
late subscribers without mouse reporting (dead wheel scroll). The cost is
one zellij client process per open pane per connection, which the zellij
server is built for (yyork ships the same model).
ring.go and session.go (fan-out, replay buffer) are deleted; manager.go
now tracks per-client attachments with liveness gating, and pty_unix.go
answers every resize frame with an explicit SIGWINCH.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
* fix(renderer): re-assert settled terminal resize; align docs with per-client attach
After each debounced resize settles, send one follow-up resize frame with
the same grid (RESIZE_REASSERT_MS). xterm only fires onResize on actual
grid changes, so a resize update the zellij client loses (raced mid-attach
or coalesced during a drag) would otherwise desync the session layout from
the pane until the next real change. The backend answers every resize
frame with an explicit SIGWINCH, so the re-assert is a no-op when already
in sync.
Comments in the terminal hook/components now describe the per-client
attach model (fresh server-side `zellij attach` per open, no replay ring).

* Move agent adapters under backend adapters
* Keep daemon ports and session out of adapter move
* Remove Better-AO naming from flake
* Keep flake as dev shell only
* Use goimports for local formatting
* Wire session manager to per-session agent adapters
Move the Agent port into internal/ports and have the claude-code and
codex adapters implement it directly, alongside their workspace-local
activity hooks and a manifest-keyed adapter registry. Rename
RuntimeConfig.LaunchCommand to Argv and update the tmux and zellij
runtimes to match.
The session Manager now resolves a real agent adapter per session via a
new ports.AgentResolver: from cfg.Harness on Spawn and the stored harness
on Restore, so one daemon runs claude-code and codex sessions side by
side. The daemon backs the resolver with the registry; AO_AGENT selects
the default harness (default claude-code), validated at startup. Removes
the temporary noopAgent stub.

* Wire the session service into the daemon
daemon.Run now builds the controller-facing session service — a session
manager over the zellij runtime, a gitworktree workspace, the shared
store + LCM, and the per-session agent resolver (AO_AGENT default,
validated at startup) — and mounts it at httpd APIDeps.Sessions, so the
session REST routes are backed by a real service. startLifecycle moves
ahead of the HTTP server so both share one LCM.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* Address Greptile review: complete the live spawn path
- Spawn and Restore now install workspace-local activity hooks
(GetAgentHooks) and run the adapter's optional PreLaunch step before
launch, via a shared prepareWorkspace helper. PreLaunch is how Claude
Code records workspace trust, so its interactive "trust this folder?"
dialog can't hang the headless pane; the spawned env now also carries
AO_DATA_DIR so the installed hook commands find the store.
- claudecode and codex hook/config writes are now atomic (temp + rename)
instead of os.WriteFile, so a crash mid-write can't leave a partial
file the agent fails to parse.
- ensureWorkspaceTrusted serializes its read-modify-write under a package
mutex, so concurrent spawns to different workspaces don't drop each
other's ~/.claude.json trust entries.

* test(ports): pin MetadataKeyAgentSessionID to domain.SessionMetadata json tag

domain.SessionMetadata.AgentSessionID is a hand-maintained invariant; this

Introduces backend/.golangci.yml (27 linters across correctness, dead-code/
boilerplate, style, and security), wires it into CI as a blocking job, and
fixes every finding so the tree starts at zero.
Config:
- 27 linters: errcheck, govet, staticcheck, errorlint, bodyclose,
sqlclosecheck, rowserrcheck, nilerr, makezero, unused, unparam, unconvert,
wastedassign, copyloopvar, prealloc, dupl, revive (incl. exported-symbol doc
comments), gocritic, misspell, usestdlibvars, predeclared, nakedret, gosec, …
- Tuned for signal over noise: govet/shadow and gocritic hugeParam/rangeValCopy/
unnamedResult disabled (idiomatic-Go false positives); sqlc-generated code and
tests get scoped exclusions; gosec G304 excluded (paths are config/run-file/
worktree-derived, not user input); nilerr excluded in cli/status.go (probe
failures are the reported status, not a command error).
CI:
- New blocking lint job (golangci-lint-action, latest binary for Go-version
compatibility).
- go-version now read from go.mod (was pinned 1.22 while go.mod declares 1.25).
Cleanup to reach zero (no behavior change):
- errcheck: wrap deferred/inline Close()/Remove()/Rollback() with `_ =`.
- gosec: tighten dir/file perms (0755->0750, 0644->0600).
- unparam: drop always-nil error return from startLifecycle; drop unused
shellPath param (zellij PowerShell) and always-500 fallbackStatus param
(writeProjectError).
- gocritic: regexp \d, s != "", switch->if, combined appends.
- revive: doc comments on all exported symbols; rename project.ProjectRow ->
project.Row (stutter); rename `max` locals shadowing the builtin.

A session can exit and run onExit (which deletes c.terms[id]) in the gap
between subscribe returning exited=false and openTerminal assigning
c.terms[id]. The delete is a no-op there since the key isn't set yet, so
the later assign resurrects a stale entry for a dead pane, trapping every
future open for that id on the connection. Re-apply the delete after the
assign when onExit fired in the window, tracked by a c.mu-guarded flag.
Add a stress regression test that races the exit against the assign.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
The exit callback enqueued the exited frame before deleting c.terms[id],
so a client reopening on receipt of exited could hit the open guard while
the entry was still set and have its open dropped. Delete first so the
cleared entry is visible by the time the client sees exited.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Opening a terminal whose session has exited left c.terms[id] set to a
no-op (already-exited path) or to a never-cleared unsubscribe (exit after
open), so the open guard silently dropped every later open for that id on
the connection until close/reconnect. Clients also saw exited/data before
the opened ack.
Ack opened before subscribe so it always precedes replay/data/exited;
have subscribe report whether the pane was already terminal and skip
registering in that case; and clear the connection entry from the exit
callback for panes that exit after open.

The session run loop closes the PTY after copyOut returns, and session.close
(via Manager.Close) closes the same PTY again. creackPTY.Close called cmd.Wait
each time, and a second concurrent Wait on the same process blocks forever, so
daemon shutdown deadlocked whenever a terminal was still attached. fakePTY is
idempotent via sync.Once, so the unit suite never exercised this; a real tmux
attach surfaced it.
Guard close+kill+wait with a sync.Once so Wait runs exactly once. Add a
regression test that double-closes a real PTY under a watchdog.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
A new subscriber could receive the same PTY bytes twice: the ring snapshot
was taken under s.mu but replayed after unlock, while copyOut appended to the
ring and fanned out as two separate lock acquisitions. A chunk appended before
the snapshot could then be fanned out after the replay, delivering it in both.
The same gap let an exited frame overtake the replay.
Make append+fanout one atomic step under s.mu (deliver) and replay the snapshot
before releasing the lock in subscribe, so the two critical sections fully
serialize and each chunk reaches a subscriber exactly once.

Construct the tmux runtime and a terminal.Manager fed by the CDC
broadcaster, and hand it to httpd.New so the /mux WebSocket surface goes
live. httpd.New now runs after the CDC substrate so the broadcaster exists
when the manager subscribes; the listener still binds before running.json
is written, preserving fail-fast on port conflict. The manager is closed on
shutdown alongside the CDC pipeline and lifecycle stack.
Add internal/terminal: a transport-agnostic feature package that attaches
a PTY to a session's tmux pane and multiplexes the byte stream to WebSocket
clients, plus a session-state channel fed by the CDC broadcaster.
The PTY is reached through a small PTYSource interface (satisfied by the
tmux runtime adapter) and spawned via an injectable spawnFunc, so fan-out,
the 50KB replay ring, and re-attach resilience all test without a real
process, tmux, or network. A tmux-guarded integration test exercises the
real creack/pty path end-to-end.
Raw PTY bytes never touch the CDC change_log; only the sessions channel is
CDC-fed. Windows PTY spawning is stubbed pending a ConPTY path.
