* 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.

* 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).

* feat(plugin): add agents plugin (first iteration)
Faithful copy of the agents plugin implementation from yyovil/better-ao
(internal/plugin/ -> backend/internal/plugin/) plus its PRD
(prds/plugins/agents/PRD.md), as a first-iteration proposal for review.
Imports are left at their original github.com/yyovil/better-ao/... paths and
are NOT yet reconciled to this repo's module; see PR description for the
integration deltas (module path, missing internal/utils dependency).

* 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.

* docs(agent): point the agent contract at internal/ports/agent.go
The Agent interface moved from internal/adapters/agent to internal/ports;
update the PRD's Goal and Agent Contract sections (and the SessionInfo
references) to match the code.

* 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
The equality between ports.MetadataKeyAgentSessionID and the json tag on
domain.SessionMetadata.AgentSessionID is a hand-maintained invariant; this
test fails loudly if either side drifts.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* refactor(adapters): use ports.MetadataKeyAgentSessionID in claudecode + codex
The native session id metadata key is defined in ports for cross-package
consumption; drop the duplicated literals in each adapter so the constant
has one home.

* test(codex): cover ensureCodexHooksFeatureEnabled TOML edge cases
The helper is a string editor over config.toml; pin its content
transformation for missing/empty files, existing [features] blocks,
the no-op case, and the legacy codex_hooks=true migration paths.

* docs(adapters): document Registry concurrency contract
Registry registration runs at daemon boot before any goroutine calls Get,
so the underlying map needs no lock; pin that contract in the doc comment
so a future change doesn't quietly introduce a race.

* style(codex): gofmt codex_test.go after constant rename
The previous commit (7c5b2a9) replaced codexAgentSessionIDMetadataKey with
ports.MetadataKeyAgentSessionID inside a map literal; the longer key threw
off gofmt's column alignment on the adjacent codexTitleMetadataKey /
codexSummaryMetadataKey lines. Caught by agent-ci's Check formatting step.

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.
