* 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

Introduces the shared platform that per-agent adapters plug into, wired for the
three shipped harnesses (claude-code, codex, opencode):
- adapters/agent/registry: single source of truth for shipped adapters
(Constructors), consumed by the daemon to resolve a session's harness.
- adapters/agent/activitydispatch + 'ao hooks' command: maps an agent's native
hook callbacks onto AO activity states (active/idle/waiting/...).
- claudecode/codex/opencode: emit SessionStart/UserPromptSubmit/Stop activity.
- HTTP + OpenAPI: report session activity state.
- db: single migration widening sessions.harness to all shipped harnesses, so
adding an adapter needs no further migration.
- domain: harness constants + --agent alias for 'ao spawn'.
Adding a new agent is now one adapter package plus a line in Constructors().

* refactor(project): manager talks to the sqlite store; drop the in-memory store
The project Manager now runs only against the durable backend store: remove the
process-local MemoryStore (and NewMemoryManager), and require a real Store. The
daemon already wires the sqlite store; tests now build a real temp-dir sqlite
store instead of the mock.
- Move Row + the Store port to project/store.go. The Store interface stays
because it is the dependency-inversion port that lets the manager reach the
backend without an import cycle (storage imports project.Row), not an extra
mock layer — there is no longer any in-memory implementation.
- NewManager requires a non-nil Store (no in-memory fallback).
- Add project/manager_test.go: List/Add/Get/Remove happy paths +
PATH_REQUIRED/NOT_A_GIT_REPO/PATH_ALREADY_REGISTERED/ID_ALREADY_REGISTERED,
PROJECT_NOT_FOUND/INVALID_PROJECT_ID, and UpdateConfig — all against a real
sqlite store (the service-logic tests #47 lacked).

* refactor(project): trim routes, consolidate package, add code-first OpenAPI
- Remove POST /reload, PATCH /{id}, POST /{id}/repair routes and their

- Merge Manager interface into manager.go; delete project.go (single-impl
split served no purpose)
- Remove dead notImplemented helper from errors.go
- Port PR #59 code-first OpenAPI generation: controllers/dto.go named
response types, specgen/build.go (4 routes), parity + drift tests,
cmd/genspec, go generate wiring; regenerate openapi.yaml
- Add swaggest deps; add YAML() method to apispec.Spec

permanently block re-registration (update queries/projects.sql and
generated gen/projects.sql.go)
- Add TestManager_ReaddAfterRemove to lock the fix

* feat(backend): HTTP daemon skeleton — config, health, runfile, graceful shutdown (#10)
Phase 1a of the Go HTTP daemon lane (#10). Stands up the loopback-only
sidecar skeleton the later REST/SSE/WS/static surfaces build on:
- config: env-driven (AO_HOST/PORT/ENV/timeouts/run-file) with zero-config
defaults; binds 127.0.0.1:3001; validates and fails fast on bad input.
- httpd: chi router with the recoverer → request-id → logger → real-ip
middleware stack and /healthz + /readyz probes. Per-request timeout is
carried in config but intentionally not global — it scopes to /api/v1 in
Phase 1b so it never throttles SSE/WS/health.
- runfile: atomic PID + port handshake (running.json) for the Electron
supervisor, with a dead-PID stale check so a crashed predecessor doesn't
block startup while a live one fails fast.
- server: bind-before-publish (port conflict fails fast), graceful shutdown
on SIGINT/SIGTERM via signal.NotifyContext with a 10s hard timeout, and
run-file cleanup on exit.
Why: the daemon must be safely supervisable as a child process — the
supervisor needs a discoverable PID/port and the daemon must not leave a
half-started process or stale handshake behind. Locking the lifecycle down
now keeps the future port split a small change rather than a rewrite.
Tests cover config defaults/overrides/validation, run-file round-trip and
live/dead PID detection, health probes, full Run lifecycle, and port-conflict
fail-fast.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* fix(backend): address Phase 1a review comments (#10)
- config: drop AO_HOST entirely — the daemon is loopback-only by design,
so making the bind host env-configurable was a security footgun
- config: use net.JoinHostPort in Addr() so IPv6 literals stay valid
- config: reject zero/negative AO_REQUEST_TIMEOUT and AO_SHUTDOWN_TIMEOUT
(time.ParseDuration accepts both; either would silently break the
daemon — instant request expiry / no graceful drain)
- runfile: split processAlive into unix/windows build-tagged files so
liveness detection is reliable on both platforms (Windows uses
OpenProcess; POSIX keeps signal 0)
- runfile: document os.Rename overwrite semantics (atomic on POSIX,
REPLACE_EXISTING on Windows) so the temp-then-rename pattern's
cross-platform behaviour is explicit
- httpd tests: give probe/waitForHealth clients an explicit per-request
timeout so a stalled connect can't hang the test on the outer deadline
* fix(backend): strip trailing blank line from runfile.go (#10)
gofmt CI was failing because removing the orphan processAlive doc
comment left an extra newline at EOF.
* fix(backend): cross-platform run-file replace + AO_HOST rationale (#10)
- runfile: introduce build-tagged atomicReplace — POSIX rename(2) on
Unix, MoveFileEx with MOVEFILE_REPLACE_EXISTING on Windows. The Go
runtime happens to do the Windows call internally already, but
invoking it directly makes the cross-platform contract explicit
instead of a runtime implementation detail
- runfile: tighten process_unix.go build tag from `!windows` to `unix`
so plan9/js/wasm fail to build rather than silently using a broken
signal-0 probe
- runfile: add TestWriteOverwritesExisting covering the stale run-file
replace path that none of the previous tests exercised
- config: anchor the loopback-only decision in the LoopbackHost doc so
the next contributor doesn't reintroduce AO_HOST without the security
rationale
* fix(backend): route chi access logs through slog/stderr (#10)
chi's middleware.Logger writes via stdlib log to stdout, but the
daemon's slog logger writes to stderr — so REST traffic and daemon
logs landed on different streams in different formats. Replace it
with a small slog-backed requestLogger that:
- Wraps the response writer via middleware.NewWrapResponseWriter so
status/bytes are accurate even when handlers return without an
explicit WriteHeader.
- Reads the request id off the context set by middleware.RequestID
(kept mounted just before this middleware so the id is available).
- Emits one structured Info line per request with method, path,
status, bytes, duration, and remote — same key=value shape as the
rest of the daemon, one stream for the Electron supervisor to
capture.
* feat(api): projects route shell (7 routes, REST-corrected) — #20
Mounts the /api/v1 surface on the skeleton router (#10·1a) and registers
the 7 canonical project routes as 501 stubs that emit a structured
PlannedRoute body documenting the future contract. Shared scaffolding
landed here (api.go, errors.go, stubs/, controllers/) so #21/#22 plug in
without re-touching the wiring.
WHY: opens the route-shell PRs in the Go HTTP daemon lane. Doing it
interface-first lets the dashboard team build against the contract
before any handler logic exists; the locked APIError envelope and
PlannedRoute shape become #19's OpenAPI source-of-truth.
REST audit corrections vs the legacy TS surface:
R3 PUT /projects/:id alias of PATCH: PUT not registered → 405.
R4 POST /projects/:id repair overload: canonical /repair; legacy 405.
R5 degraded GET returns 200 with error field: discriminator status.
R6 ok/success flag flips: drop on 2xx; return affected resource.
R9 bare {error: msg}: locked {error,code,message,requestId,details?}.
Legacy paths are deliberately NOT registered; each canonical handler
carries PlannedRoute.Legacy so consumers can discover the migration.
Zod schemas (TrackerConfig, SCMConfig, AgentConfig, ReactionConfig,
LocalProjectConfig, RoleAgentConfig) ported to typed Go structs with an
Extra map reserved for .passthrough() round-tripping in later PRs.
Closes part of #18; targets feat/issue-10 until #14 merges.
* refactor(api): collapse ProjectService → ProjectManager — #20
Controllers now depend on ONE inbound interface per resource — ports.ProjectManager —
mirroring the existing ports.SessionManager + LifecycleManager pattern.
Whether the manager impl reaches into the registry, the LCM, an outbound
port, or all three is its own concern; the HTTP layer no longer has to
know any of that.
WHY: the original split named the boundary type "ProjectService" and put
it in a sibling services.go. That implied a second category of port
distinct from inbound.go's *Manager interfaces, even though they play
the same role (things HTTP/CLI call into the core). Per review feedback,
collapse them onto one Manager-per-resource pattern.
Mechanical changes:
- ports/inbound.go gains ProjectManager next to SessionManager.
- ports/services.go renamed to projects.go; keeps only the DTOs the
ProjectManager methods take/return.
- ProjectsController.Svc renamed to Mgr; APIDeps.Projects type bumped
to ports.ProjectManager.
All tests pass unchanged; no behavioural change.
* refactor(api): replace stubs/ with OpenAPI-as-source-of-truth — #20
The first cut of the route shell duplicated each route's contract twice:
once as a Go literal (stubs.PlannedRoute{...}) in the controller, and
implicitly in the PR description. The Go literal was ~230 LoC of pure
throwaway that would be deleted in handler-impl PRs.
This commit eliminates the duplication:
- backend/internal/httpd/apispec/openapi.yaml: full OpenAPI 3.1 doc
covering the 7 project routes + shared schemas (Project, APIError,
config types). x-replaces records the legacy → canonical mapping
REST-audit corrections produced.
- apispec/apispec.go: //go:embed the YAML, expose Operation(method,
path) → the spec slice as a map, NotImplemented(w, r, method, path)
→ 501 with that slice embedded as `spec`.
- controllers/projects.go: each of 7 handlers is now a one-liner:
apispec.NotImplemented(w, r, "GET", "/api/v1/projects").
- /api/v1/openapi.yaml serves the embedded document so tooling
(SDK gen, the validator slated for #19, dashboard dev tools) can
fetch the whole spec from the same origin as the routes.
- stubs/ package deleted.
When a real handler lands, only the apispec.NotImplemented line goes
away — nothing else does. The spec stays as documentation; consumers
never had to know it was throwaway. #19 (OpenAPI follow-up) is now
half-folded into this PR; the validation middleware remains its own
follow-up.
Tests reshaped: assert envelope + spec.operationId + spec.x-replaces
(replaces the old planned.legacy assertion); add TestOpenAPIYAMLServed
to cover the static spec serve; add apispec_test.go for embed/lookup
behaviour.
* refactor(api): move projects contract to internal/project package — #20
Pilots the feature-package layout the backend is migrating toward: a
resource's inbound interface and its DTOs live with the resource, not in
a central ports/ catch-all.
WHY: review flagged ports/ as vague. It conflates three jobs — the
outbound capability seam (legit), single-impl inbound interfaces (Go
idiom wants these consumer-side), and DTOs that aren't ports at all.
This moves the projects contract out as the reference shape #21/#22
follow; the merged session/lifecycle/outbound contracts are left
untouched and migrated separately.
Scope: INTERFACE ONLY. No implementation — handlers still answer via
apispec.NotImplemented and the injected project.Manager stays nil. The
impl lands in a later handler-impl PR.
Changes:
- new internal/project: project.go (Manager interface, 7 endpoints) +
dto.go (AddInput/GetResult/UpdateConfigInput/RemoveResult/ReloadResult,
moved verbatim from ports/projects.go, Project-prefix dropped).
- ports/projects.go deleted; ProjectManager removed from ports/inbound.go.
outbound.go and facts.go untouched.
- controllers/projects.go and httpd/api.go depend on project.Manager.
Domain entities (Project, ProjectSummary, DegradedProject, config types)
stay in domain/ as shared vocabulary.
go build/vet/test/gofmt all clean; no behavioural change.
* refactor(api): consolidate project types into internal/project — #20
Addresses PR review: (1) "why are config_types required at the moment?"
and (2) "project objects already defined in project/ — how do we
differentiate?"
Both had the same root cause: project types were split across domain/
and project/. Fix — keep ALL project types in the project package; only
domain.ProjectID (shared with sessions/lifecycle/workspace) stays in
domain.
- domain/project.go → project/types.go: Project, Summary, Degraded
(renamed from ProjectSummary/DegradedProject; the package name carries
the "Project" prefix now).
- domain/config_types.go deleted. Kept only the 4 shapes the projects
API actually exposes — TrackerConfig, SCMConfig, SCMWebhookConfig,
ReactionConfig — moved into project/types.go. Dropped AgentConfig,
AgentPermission, RoleAgentConfig, LocalProjectConfig (zero references)
and the speculative `Extra map[string]any` passthrough fields (no
marshaller existed, so they silently dropped data — premature).
- project/dto.go + project/project.go reference the local types; ids
stay domain.ProjectID.
Net: one home for project types, no dead code. go build/vet/test/gofmt
clean; no behavioural change (handlers still 501 via apispec).

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.
Add the two real outbound adapters that replace the in-memory fakeStore:
internal/storage/sqlite (persistence satisfying ports.LifecycleStore) and
internal/cdc (transactional-outbox publisher, JSONL delivery, durable
consumer). Wire them into main.go alongside the Lifecycle Manager and reaper
so the write path is live end-to-end: LCM.Upsert -> store -> outbox -> JSONL
-> broadcaster.
Storage (internal/storage/sqlite):
- modernc.org/sqlite (pure Go, no CGO) for clean cross-compile; goose
embedded migrations; sqlc-generated typed queries under gen/.
- Atomic Upsert: session row + change_log + outbox written in one tx.
- revision is an optimistic-concurrency (CAS) check: insert requires
revision 0 and persists 1; update requires loaded revision == stored and
bumps +1; zero rows affected returns a revision-mismatch error.
- Metadata is an opaque map in session_metadata, off the CDC path.
- Durable reaction_trackers (fixes the in-memory-only escalation budget that
re-fired human pages on restart).
CDC (internal/cdc):
- Publisher drains the outbox to a JSONL log; size-based rotation with a
reset marker.
- Consumer tails via byte cursor, detects rotation (os.SameFile), resyncs
from a full-state snapshot on gaps, and tracks a durable consumer_offsets
cursor.
- Janitor reclaims acknowledged outbox rows.
- Broadcaster is the in-process fan-out port the FE transport will subscribe
to (WS/SSE wiring deferred).
Composition root (main.go + *_wiring.go):
- startCDC stands up publisher/consumer/janitor + broadcaster.
- startLifecycle constructs the LCM, makes escalation budgets durable via
WithReactionStore, teaches it to enumerate sessions via WithSessionLister,
and starts the reaper.
- Notifier, AgentMessenger, and the reaper's runtime registry are TEMPORARY
no-op/empty stubs (lifecycle_wiring.go) with TODO markers; see the PR
description for how to fill them in.
Tests: contract-parity, revision CAS, outbox atomicity, CDC ordering and
idempotency, rotation/resync, janitor vacuum, reaction durability across a
simulated restart, and composition-root adapters. gofmt/build/vet clean and
go test -race ./... green.

daemon's slog logger writes to stderr — so REST traffic and daemon
logs landed on different streams in different formats. Replace it
with a small slog-backed requestLogger that:
- Wraps the response writer via middleware.NewWrapResponseWriter so
status/bytes are accurate even when handlers return without an
explicit WriteHeader.
- Reads the request id off the context set by middleware.RequestID
(kept mounted just before this middleware so the id is available).
- Emits one structured Info line per request with method, path,
status, bytes, duration, and remote — same key=value shape as the
rest of the daemon, one stream for the Electron supervisor to
capture.
