test / test (push) Has been cancelled
Verified the tree against docs/plans/code-review-2026-08.md and finished the tasks that were only partly done, plus two defects the pass introduced. - bcrypt: the setup account was still hashed at DefaultCost (10). The work factor now has one definition, auth.BcryptCost = 12, used everywhere. - rate limiter: protecting blocked buckets from eviction was unbounded — an attacker with many source addresses could grow the map by making each one fail its way to blocked. Blocked buckets are now evicted past maxBuckets * 4, nearest expiry first, logged once per window. Tests cover both halves. - postqueue: the 5s timeout left the output size unbounded; reads are now capped at 4 MiB and report truncation. - spec references: the ~76 `spec N` citations CHANGELOG [0.5.0] claimed were gone are removed from build/, deploy/, the first two migrations and the release workflow, with the affected comment paragraphs re-wrapped. Comments only; shell/YAML/SQL syntax re-checked. - schema-migrations.md: schema section was headed v9 with the chain at v10, and three links pointed at deleted plan files. - internal/configsafe: the shared empty/forbidden-character check behind the OpenDKIM and Postfix config writers; each writer keeps its own forbidden set. - dropped the parseDomainRateLimitForm/parseAppRateLimitForm pass-throughs left behind by the parser merge (only their own tests still called them). - plan doc now carries a status table: what shipped, what was already in place, what was declined (//go:build linux for the /proc reader) and the open CSRF-token question. Not done, each its own phase: typed template data structs, log/slog, DMARC service and handler tests, error-page/corrupted-backup tests, backup re-auth.

"""Supervisor event listener: bring the container down on unrecoverable failure.
|
|
|
|
If any managed program exhausts its restart retries and enters FATAL, this
|
|
listener signals supervisord (its parent) to terminate, so the whole container
|
|
exits and Docker's `restart` policy can recreate it cleanly — rather than
|
|
lingering "alive" with a dead Postfix/OpenDKIM/panel.
|
|
|
|
Communication with supervisord uses the event listener protocol over stdin and
|
|
stdout, so stdout must carry only protocol tokens.
