Module registry 

daemon.json / daemon.lock / daemon.pid under registry_dir() (PLAN-phase2 §2.11). The flock on daemon.lock is THE liveness oracle (jcode socket.rs:89-139): a daemon is alive iff someone holds the lock. A socket file with no lock holder is stale and gets unlinked. Nobody unlinks on ECONNREFUSED alone.

Re-exports

pub use crate::events::registry::DaemonPaths;

Structs

DaemonInfo

daemon.json — pid + profile + paths only. Never credentials.

DaemonLock

Held for the daemon’s lifetime; dropping releases the flock.

SpawnLock

Held while a client spawns the daemon; dropping releases it.

Functions

is_alive

Liveness probe: try to take the lock; success means nobody holds it (dead or never started) — release immediately. Never unlinks anything.

read_daemon_json

reap_stale

Unlink sock/json/pid if — and only if — no daemon holds the lock. Returns true when something stale was removed.

write_daemon_json

Write daemon.json + daemon.pid atomically (tmp + rename), 0600.

write_private_atomic

0600 tmp + rename (reload-state).
