* fix(pty): release ptmx fd on natural exit + defuse SIGHUP-to-recycled-pid Daemons accumulated ptmx fds over time because node-pty's UnixTerminal only releases the master fd when destroy() runs. On the natural-exit path (the common case — user closes a tab, shell runs `exit`) nothing ever calls destroy(), so the fd leaks until GC. On macOS this eventually hits kern.tty.ptmx_max=511 and all new terminals fail to spawn. Fix: release the fd synchronously on every teardown path (natural exit, explicit kill, stale SSH spawn, daemon shutdown) and close the concurrent SIGHUP-to-recycled-pid hazard inside node-pty's UnixTerminal.destroy(). - src/main/daemon/pty-subprocess.ts: synchronous POSIX proc.kill neutralization inside proc.onExit; dead guards on forceKill/signal so they never target a reaped-and-possibly-recycled pid - src/main/daemon/session.ts: new disposeSubprocess() for already- exited sessions (fd release only, no SIGKILL) — avoids sending SIGKILL to a recycled pid during daemon shutdown - src/main/daemon/terminal-host.ts: dispose loop routes on isAlive — live sessions get forceKillAndDisposeSubprocess (SIGKILL + fd release), exited sessions get disposeSubprocess (fd release only) - src/main/providers/local-pty-provider.ts: same POSIX kill neutralization at top of onExit for the legacy local path - src/relay/pty-handler.ts: same neutralization in wireAndStore; disposed flag guards all public entry points; dispose() uses SIGKILL (not SIGTERM) before destroy since the relay is exiting; killTimer fallback + immediate-shutdown + stale-spawn cleanup all call disposeManagedPty + ptys.delete so wedged children (D-state, bad NFS) can't leak map entries against the 50-PTY cap Windows is exempt everywhere — WindowsTerminal.destroy IS a kill() call internally (closes the ConPTY agent), so neutralizing would turn destroy into a no-op and leak the agent. See docs/fix-pty-fd-leak.md for the full design.

In the typical case (break at count=0) the cleanup body never runs and low_fds[0] — a /dev/ptmx handle — leaks per spawn. Fixed upstream in microsoft/node-pty af053f2 (PR #882), not in any 1.1.0 release. Backport the 3-line cleanup-loop fix as a pnpm patch. E2E validated against a dev daemon: 200 spawn/kill cycles kept the daemon's ptmx fd count flat at baseline; prior runs reproduced linear 1-per-spawn growth. Also documents the native root cause as a status addendum in docs/fix-pty-fd-leak.md — the JS-side destroy() discipline previously landed is still load-bearing for the SIGHUP-to-recycled-pid hazard and for synchronous fd release on daemon shutdown. Co-authored-by: Orca <help@stably.ai> * fix(pty): capture stable kill spy ref in pty.test.ts destroyPtyProcess reassigns proc.kill = () => {} on POSIX to defuse the SIGHUP-to-recycled-pid hazard (see docs/fix-pty-fd-leak.md). After that reassignment, proc.kill.mock is undefined and the assertions crashed in CI. Capture a stable reference to the vi.fn() before it gets reassigned.

Orca CLI Docs
Keep this folder focused on the durable references for Orca's public CLI and runtime model.
Keep These Docs
orca-cli-focused-v1-status.md- What is actually implemented and intentionally in scope now.
orca-cli-v1-spec.md- The public CLI contract, selector grammar, JSON envelope, and command semantics.
orca-runtime-layer-design.md- Why the runtime layer exists and which boundaries it owns.
orca-cli-bundled-distribution.md- How the bundled desktop-app distribution and PATH registration model works.
Why The Folder Is Small
Earlier design and implementation work produced several planning and evaluation docs. Those were useful while the feature was taking shape, but they were intentionally removed once the implementation converged so future readers are not forced to choose between multiple overlapping sources of truth.
