When codex app-server fails outside the OAuth-classified path
(non-auth turn/start errors, plain TimeoutErrors, generic turn-ended
status, subprocess silently exits, hard deadline timeout), the user
got a bare 'Internal error' / 'turn/start failed: ...' with no
context. Diagnosing config/provider/auth-bridge issues forced a
re-run with verbose codex flags.
Add a _format_error_with_stderr helper that appends the last few
stderr lines via agent.redact.redact_sensitive_text(force=True),
and use it at every catch-all error site:
- ensure_started() failures (codex init / thread/start) now return
a TurnResult.error with should_retire=True instead of bubbling
- non-OAuth turn/start CodexAppServerError / TimeoutError
- subprocess-died branch (previously dumped raw stderr_blob[-300:]
with no redaction — a leak risk)
- turn ended with non-completed status
- hard turn-timeout deadline
OAuth-classified failures and the post-tool quiet watchdog already
produce clean hints and stay unchanged. The redactor catches sk-*,
gh*_*, Authorization: Bearer, query-string tokens, JWTs, private
keys, etc., so provider error payloads can't leak into chat output
or trajectories.
Inspired by openclaw#80718, adapted for our app-server transport.
