Four findings from security audit (internal/security/credential-token-backlog.md):
1. STDERR LEAK — molecule-git-token-helper.sh:146,153 logged ${response}
on platform errors. The response body MAY contain the token in some
failure modes (alternate JSON key shape on partial success). Now:
- capture curl's stderr to a tmp file (not $response) so we can log
the curl error message without ever interpolating the response body
- on empty-token branch, log only response size (bytes) for debug
2. CHMOD 600 — already in place at lines 116, 124, 223 (verified, no change)
3. RESPAWN SUPERVISION — entrypoint.sh wrapped daemon launch in a
while-true bash loop with 30s back-off. Without this, a daemon crash
silently leaves the workspace stuck on an expired token until the
container restarts. Logs to /home/agent/.gh-token-refresh.log
(agent-writable; /var/log is root-owned).
4. JITTER — molecule-gh-token-refresh.sh: added 0..120s random offset to
each sleep so 39 containers don't synchronize their refresh requests
against the platform endpoint.
Also:
- Daemon now sends helper output to /dev/null instead of merging stderr,
belt-and-suspenders against any future helper change that might write
the token to stdout.
- Daemon log lines include rc=$? on failure for actionable triage.
Inherent risks (org-wide token blast, prompt-injection theft, bearer
in volume, no audit log) tracked in internal/security/credential-token-backlog.md
as separate roadmap items.
