Summary

Root-causes item #164's 15h incident: an expired-auth dispatch failure had its real stderr error text silently dropped by diagnostic_suffix (stdout preferred over stderr), and with no auth-expiry classifier the failure fell through to the rate-limit cooldown-and-retry path — burning the entire retry budget against a credential that fails identically every time.

• agent_launch::diagnostic_suffix now includes a non-empty stderr tail alongside stdout instead of only falling back to it when stdout is empty.
• auth_runner::is_auth_expired + ExitKind::AuthExpired classify auth-expiry distinctly from rate limits, with a conservative starter phrase list (re-authenticate / session expired / invalid api key / 401 unauthorized, etc.). The interactive retry loop (auth_runner::run) now prompts for re-auth on this case instead of rotating to a differently-broken profile.
• cli::work::handle_auth_expired intercepts before classify_and_cooldown: fails the job immediately (fatal: true, skipping the job queue's retry budget via agentflare-jobs::queue's existing fatal short-circuit), applies an idempotent auth-expired label, logs the alert to both stderr and the job's own log file, and reuses notify_human_gate for immediate human alerting instead of 15h of silence.
• work_item_pipeline's two sdd_loop map_err sites short-circuit their own step-level RetryPolicy via StepResult::Failed instead of a generic Err, so a surfaced auth-expiry message isn't retried into a WorkflowError::StepFailed blob indistinguishable from a network blip.
• handle_auth_expired/ensure_auth_expired_label were split into src/cli/work_auth_expiry.rs (+ work_auth_expiry_tests.rs) to keep work.rs under its frozen LOC-gate limit, mirroring the existing work_duplicate_pr.rs/work_duplicate_pr_tests.rs split already in this file.
• build_finalize_step's only map_err (the item_done MCP call) was confirmed unrelated to agent-dispatch/auth failures and left untouched, per the item's explicit scope carve-out.

Test plan

• cargo check --tests --bin agentflare clean
• cargo clippy --bin agentflare --tests clean (only pre-existing unrelated unsafe-block warnings)
• cargo test --bin agentflare cli::work — 77 passed
• cargo test --bin agentflare work_item_pipeline — 90 passed, 2 ignored
• cargo test --bin agentflare agent_launch — 38 passed, 1 ignored
• cargo test --bin agentflare auth_runner — 8 passed (incl. new is_auth_expired/AuthExpired cases)
• bash scripts/loc-gate.sh clean

Closes item #173.

Summary by CodeRabbit

• Bug Fixes
  • Authentication-expiration failures are now detected separately from rate limits.
  • Expired sessions stop immediately instead of triggering unnecessary retries.
  • Affected work items receive an auth-expired label, a clear alert, and human notification.
  • Recoverable stale sessions can still refresh and retry as before.
  • Diagnostic messages now include both captured standard output and error output when available.

Changes

Process diagnostics

Layer / File(s)	Summary
Combined failure output src/agent_launch.rs, src/agent_launch_tests.rs	Failure diagnostics now include both non-empty stdout and stderr streams. Tests verify that stdout appears before stderr.

Authentication expiry handling

Layer / File(s)	Summary
Authentication expiry classification src/auth_runner.rs	Expired-session and unauthorized messages use the AuthExpired classification. The runner records the profile error, shows re-authentication instructions, and exits without retrying.
Work command expiry handling src/cli/work.rs, src/cli/work_auth_expiry.rs, src/cli/work_auth_expiry_tests.rs	The work command handles authentication-expiry failures before rate-limit classification. It labels the item, emits an alert, notifies a human, and returns a fatal outcome without retry delay.
Pipeline terminal failure propagation src/work_item_pipeline.rs	Role-agent and judge-agent authentication failures become non-retryable step failures. Other failures retain stale-session cleanup and retryable error handling.

Merge Risk: 🟡 Moderate · up to 60e14

Expired credentials can still trigger retries for mixed error messages, and simultaneous failures may miss the alert label on some items. Resolve both paths before merging.

Check authentication expiry before rate-limit matching.

When a nonzero-exit message contains both "401 unauthorized" and "try again", categorize_exit returns RateLimited first. run then retries instead of taking the terminal AuthExpired path. Reverse these checks and add an overlap test.

Proposed fix

-    if is_rate_limited(stderr) {
-        return ExitKind::RateLimited;
-    }
     if is_auth_expired(stderr) {
         return ExitKind::AuthExpired;
     }
+    if is_rate_limited(stderr) {
+        return ExitKind::RateLimited;
+    }

Handle the concurrent label-creation conflict.

labels has a unique active (name, project_id) index, so concurrent calls cannot create duplicate auth-expired labels. However, label::create uses a plain INSERT, and ensure_auth_expired_label converts a uniqueness error to None. The losing job therefore skips item_add_label and leaves its item unlabeled. Re-read the existing label after a creation conflict, and add a concurrent test.
