Crate planarian_daemon 

planariad’s core, independent of the real backends: the tick loop and the request handler. The planariad binary instantiates it with the systemd, udev and nixos-rebuild backends; the gym, with the fake machine.

Modules

approval

§16 Approvals show the change (owner decision, Nov 2): the configuration a generation transition that asks would apply. The core builds it from the derived facts, which come from the evaluated generations (§11), never from the proposal. planarian approve, the console and the notice show it; approve --json and IPC Pending.diff carry the same data. A diff that differs when the facts are re-derived at approval changes the token’s bound_to (the binding hashes the facts), so the approval does not apply and the change asks again.

config

/etc/planarian/config.json, written by the NixOS module, and the canonical probes shipped in the core package (I10).

core

The daemon loop (SPEC §10, §13) and request handling (§14, §16).

hold

§12d Network security fails closed, the daemon’s half (#35 part 1).

hooks

The two Phase A hooks (§9, §10): a signed external desired-state source, verified and cached with no producer and no network, and a signed health report emitted locally with the minimal disclosure profile.

render

Plain-language rendering of transitions, records and results.

renew

Lease renewal (§12): while this daemon is busy in a long backend call, a thread renews the leases it holds, so the watchdog does not take over from a live daemon. It keeps one journal handle and catches up on what others appended (sync_ledger), rather than opening the journal again each time: opening reads the checkpoint and the whole log, and after a compaction the rest of the store, so renewing would cost the journal’s size every 20 s and be slowest when the journal is fullest.

snapshot

Read-only answers while the core is busy.

Constants

STARTUP_GRACE

The default startup grace (services.planarian.startupGrace).
