Remote Control

The remote-control bridge now re-registers sessions it was running when it restarted.

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

What

When the headless remote-control bridge shuts down it now records which sessions were active, and on restart it re-registers and re-queues them instead of losing them.

Details
  • The saved list and its timestamp are read back from the bridge's pointer file, and only reused if the timestamp is inside a fixed freshness window.
  • Startup logs re-queuing N session(s) interrupted by the previous shutdown, and each resume reports success or env_reuse_declined.
  • Persisting the list on shutdown is controlled by tengu_daemon_upgrade_defer_busy, which falls back to on, so absent remote config the daemon does persist.
  • Pointer-file writes moved from a bare hourly timer onto a write queue.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
