* refactor(cli): remove lifecycle-worker subprocess model, run polling in-process
Replaces the per-project `ao lifecycle-worker` subprocess with an in-process
polling loop managed inside `lifecycle-service`. All registered projects are
now polled from the single long-lived `ao start` process.
- Drops the `lifecycle-worker` command and its registration.
- Rewrites `lifecycle-service` around a `Map<projectId, ActiveLoop>`,
with SIGINT/SIGTERM/beforeExit graceful shutdown.
- Removes PID-file coordination (PID file, log file, status, etc.) —
these only existed to track subprocess state.
- Per-project error isolation is preserved: the core lifecycle manager's
`pollAll()` already catches per-cycle errors, and stop failures in one
project can't prevent others from stopping.
- Updates `start`/`spawn` callers and tests to drop the PID/logFile shape.
- Adds `lifecycle-service.test.ts` covering idempotency, unknown projects,
error isolation across projects, and graceful stop-all.
Closes#1185
* fix(cli): address bugbot review on lifecycle-service in-process refactor
- `ao spawn` / `ao batch-spawn` no longer call `ensureLifecycleWorker`.
That call used to start `setInterval` polling in the one-shot spawn
process, which (a) kept the CLI alive forever after the session spawned
and (b) duplicated polling already running in `ao start`. Replaced with
a `warnIfAONotRunning()` helper that checks `running.json` and prints a
hint if the orchestrator isn't up.
- `ao stop` no longer calls `stopLifecycleWorker`. That call always ran
against a fresh in-memory map (stop is a separate process from start),
so it always returned false and printed "Lifecycle worker not running"
misleadingly. SIGTERM to the `ao start` PID already triggers the shared
shutdown handler in `lifecycle-service`, which stops every loop.
- Drop duplicated shutdown closure inside `registerSignalsOnce` — signal
handlers now reference `stopAllLifecycleWorkers` directly.
- Update tests accordingly: spawn.test.ts mocks `running-state.getRunning`,
start.test.ts drops `stopLifecycleWorker` expectations.
* fix(cli): drop SIGINT/SIGTERM listeners from lifecycle-service
Installing listeners for those signals removes Node.js's default
"exit on signal" behavior (per Node docs: "its default behavior will
be removed — Node.js will no longer exit"). Since the registered
listener doesn't call process.exit(), the `ao start` process would
hang on SIGTERM with the setInterval timer keeping the event loop
alive forever — effectively breaking `ao stop`.
Default signal handling terminates the process cleanly; the OS
reclaims the interval timer and dashboard child. `stopAllLifecycleWorkers`
stays exported for callers that want explicit cleanup before exit.
* fix(cli): project-scoped spawn warning + flush lifecycle health on exit
Addresses reviewer feedback on PR #1186:
- `warnIfAONotRunning` now takes a projectId and warns not only when no
AO is running, but also when the running instance isn't polling the
target project (e.g. `ao start A` then `ao spawn` in B left users
silent about the fact that B wasn't being polled).
- `running.json` now records only the project this `ao start` actually
polls, not every project in config. Previously this list was a lie —
`ensureLifecycleWorker` is called for the selected project only.
- `ao start` installs SIGINT/SIGTERM handlers that call
`stopAllLifecycleWorkers()` (flushing per-project "stopped" health
state) and then `process.exit()`. Installing the handler safely
requires an explicit exit because SIGINT/SIGTERM listeners remove
Node's default exit behavior.
* fix(cli): remove dead stopLifecycleWorker, add missing test mock
Addresses bugbot comments on PR #1186:
- Delete `stopLifecycleWorker` from `lifecycle-service.ts`. It was only
called from `ao stop` in the old subprocess model; in the in-process
model, SIGTERM to the `ao start` pid + the shutdown handler in
`start.ts` covers cleanup. No production caller remains.
- Add `stopAllLifecycleWorkers: vi.fn()` to `start.test.ts`'s
`lifecycle-service.js` mock. Without it, `vi.mock` replaced the module
and the named import resolved to undefined; the shutdown handler's
try/catch would silently swallow the resulting TypeError, hiding any
regression in how shutdown is wired.
- Update `lifecycle-service.test.ts` to drop references to the removed
export (one test removed, one repurposed as a no-op smoke test for
`stopAllLifecycleWorkers` against an empty active map).
