Its registry row and test rows are already in f7f02abb; this is the probe they call. Each KV_<module>_<name> and LOG_<module>_<name> stream is said filling at three quarters of its max_bytes, and kept while a finding is written until under seven tenths. One read of every stream, so the bus module not answering is the probe failing to run, which clears nothing; bucket-or-log-unread is not raised.
mesh-self-check
Holds the seat mesh-self-check (novox/hq ADR 0564 §6): the mesh's self-check, moved out of the controller. Go, one
binary (cmd/mesh-self-check), served by a runtime of its own on its own bus account (runs-as), so that its account
alone writes its buckets.
What it does
Every five minutes (the first run a minute after it starts) it runs its registry of probes, each within thirty
seconds. A probe is one live invariant of a design, with its assertion as the controller had it, reading its facts on
the bus (the bus module's tools for the bus's own state). A probe whose facts have no home on the bus yet answers
deferred, naming them: never a pass. A probe that cannot run is said in the verdict at once, and written as a finding
of its own (probe.<id>.failed) when the next run cannot run it either.
What a probe finds is written as a finding, one key <scope>.<id>.<kind> per fault, only when what it says changes, and
deleted when a run no longer sees it. The condition keeper (mesh-conditions) raises and clears conditions from them.
A finding one look can be wrong about (a consumer behind after a burst) is written when two runs in a row see it.
Every run ends with the event checked, the body of the controller's doctor-heartbeat, which the watchman (S10) and
mesh-watcher on another machine hear: a self-check that stops checking is said through a path that does not pass
through it.
What it keeps
mesh-self-check_findings: what it finds wrong now.mesh-self-check_verdict: the keylast, the last run whole.mesh-self-check_verdicts: every run (each probe's findings at most twenty), kept a week by the bucket's age.
Its verbs and tools
mesh-self-check.doctor: the last verdict;run=trueruns now;probe=<id>one probe whole.mesh-self-check.probes: the registry, with what each deferred probe lacks.self_check_findings,self_check_verdicts: the reads of its buckets.
