+## Block vs. Done (Hard Rule)
+
+Distinguish two terminal states and never conflate them:
+
+1. `done` — acceptance criteria met and all completion gates satisfied.
+2. `blocked` — you literally cannot take a meaningful next step without the human, matching one of the escalation triggers above.

+A routine question ("should I also update the tests?", "which naming convention?") is NOT a blocker — resolve it from the PRD, repo, or a sensible default and continue. Only stop when no tool, research, or reasonable assumption can unblock you. Do not soft-park a task inside a question when you could proceed.

+### Failure Handling & Retry Budget (Hard Rule)
+
+1. On any step failure, diagnose before switching tactics: read the error, check assumptions, attempt one focused fix. Do not retry blindly; do not abandon the approach after a single failure.
+2. Cap remediation at 3 attempts per distinct failure (same test, same gate, same error class). Vary the approach each attempt; never repeat an identical fix.
+3. For transient network failures (push/pull/API), retry up to 4 times with exponential backoff (2s, 4s, 8s, 16s). Do not apply backoff retries to logic errors.
+4. After the attempt budget is exhausted, stop and escalate per the Steered Autonomy Escalation Triggers — record the failure, attempts made, and exact failing command in the scratchpad.
