Review fixes for COD-54:
- Generated hook curl commands now present X-Codeman-Hook-Secret, read from
the secret file AT EXECUTION TIME via $CODEMAN_HOOK_SECRET_FILE (exported
into every managed session's env by tmux buildEnvExports / the direct-PTY
env builders). Without this, every local hook 401'd the moment a managed
tunnel came up — the enforcement existed but nothing presented the secret.
Path-not-value keeps the secret off command lines and out of config files,
and running sessions pick up a newly generated secret with no respawn;
server.start() ensures the file exists up front.
- Hook-secret failures now count into a DEDICATED per-IP bucket
(hookSecretFailures) instead of the shared authFailures map. Legacy
(pre-secret) hook configs fire constantly from 127.0.0.1; counting their
401s against the shared bucket would 429 every cookie-less loopback
request — locking out the Basic-Auth login path (and, through a tunnel,
every client, since tunneled traffic also arrives as 127.0.0.1).
- docs/security-architecture.md: secret-gated hook exemption, dedicated
bucket, COD-55 refusal, and the residual caveat for EXTERNAL loopback
proxies (user-run cloudflared / tailscale serve), which the
managed-tunnel probe cannot see.
- test/cod54-hook-event-auth.test.ts: +3 tests — login path unaffected
after hook-bucket exhaustion; generated hooks reference the header +
$CODEMAN_HOOK_SECRET_FILE without embedding the value; env builders
export the path only.
