Module unix 

Functions

next_signal 🔒

Await the next delivery of a Unix signal, or never resolve if the signal stream couldn’t be installed. Lets run_unix’s select! treat an absent handler as “this branch is dormant” rather than special-casing Option at every poll.

run_unix 🔒

Unix (macOS/Linux) main flow: resolve paths → bind launcher IPC socket (single-instance signal) → set up reducer / event log / saga coordinator / IPC server → spawn srv → spawn host with srv endpoints AND the launcher socket path in env → supervised wait → cleanup.
