Finishes the sweep of prose that said the publisher unit writes or carries the OIDC client secrets: rust docs, nix comments and option descriptions, test names and docs.
A client with a secret in the store or in a leftover file but no digest gets the digest of that secret instead of stopping the unit. The password reaches authelia's prompt through a pty, not argv. A lost mint race takes the winner's secret. Also name the mint, not the publisher, in the remaining rust docs.
A swarm-ci-metrics host unit on a 5-minute timer lists every forge
repo's Actions runs as the new read-only ci-metrics account and pushes
each finished run's duration and queue wait over OTLP, stamped at the
run's stop time. The first pass backfills from run 1. swarm-controller
mints the account's token into bao and keeps a ci-metrics team with
read on the Actions unit in every organisation.
