Module config 

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

Structs

FileConfig

PostureDecl

What the failure posture is, and what is waiting (§12d, P16). A generation switched live can strengthen the posture or shorten the timeout at once; a weaker declaration takes effect when it is booted, because the posture follows the booted generation until then.

RuntimeOptionConfig

Constants

BOOTED_CONFIG

The configuration of the generation this machine booted (§12d, P16).

CONFIG

CORE_HASH_RECORD

The running generation’s record of its core files’ hashes (I2, §12d), the one planarian-recovery checks; PLANARIAN_CORE_HASH overrides it.

Functions

core_hash

SystemState.core_hash (P19): the hash of the recorded core-hash file’s bytes. Zero only when there is no record (a development build); any other read failure is an error, never a value (§18 rule 21). A damaged record is the watchdog’s integrity finding (I2), not this.

default_boot_ready_secs 🔒

default_health_secs 🔒

is_admin

Is uid root or a member of group (by /etc/group and /etc/passwd)?

load_canonical

Canonical probes from the core package: <prefix>/share/planarian/canonical.json next to the running binary, never from the generation (I10).
