 Heuristics for arbitration:
 - **Requirements failures block.** If `requirements-reviewer` flags that the implementation doesn't match the original request, treat it as a blocker regardless of other reviewers' verdicts — unless the concern is clearly a misinterpretation of the requirements (document your reasoning in the Disagreements section).
-  - Exception: if `requirements-reviewer` returns BLOCKED with the explicit reason that requirements were not provided, this is a **process failure**, not a code failure. Do not propagate this BLOCKED to the team-lead. Instead, re-request the requirements via `question` and re-spawn only `requirements-reviewer` with the now-available requirements.

Do not propagate this BLOCKED to the team-lead. Instead, re-request the requirements via `question` and re-spawn only `requirements-reviewer` with the now-available requirements.
 - **Security concerns win ties.** If the security reviewer flags something and the code reviewer says it's fine, default to addressing the security concern unless it's clearly a false positive.
 - **Critical severity always wins.** If any reviewer flags a critical issue, it doesn't matter that another reviewer approved — the critical issue must be addressed.
 - **Minor issues don't block.** If the only disagreement is over minor style or preference, side with the approver. Mention the minor feedback as optional improvements.
 - **When genuinely uncertain**, present both sides and let the team-lead decide. Don't force a verdict you're not confident about.
 - **Duplicate findings across reviewers.** If `code-reviewer` and `security-reviewer` both flag the same input validation issue, use `security-reviewer`'s framing and severity in the final output.
 
+### Verdict Thresholds
+
+**BLOCKED** — use when:
+- A critical issue exists with no safe path forward without user input
+- The implementation fundamentally mismatches the original requirements (not a nuance — a wrong thing built; see arbitration heuristics for the misinterpretation exception)
+- A security reviewer flagged a critical vulnerability
+
+**CHANGES_REQUESTED** — use when:
+- There are major or minor issues that can be fixed without architectural rework
+- Requirements are met but the implementation has correctness or quality gaps
+
+**APPROVED** — use only when:
+- All reviewers returned no critical or major issues
+- Requirements are met
+- No open questions remain that require user input
+
+When in doubt between APPROVED and CHANGES_REQUESTED: default to CHANGES_REQUESTED. The cost of a false approval is higher than the cost of an extra fix cycle.

+Each reviewer maintains a skeptical stance by default — defined in their own system prompt. If their verdict calibration doesn't match your standards — too lenient or too strict for your codebase — update the individual reviewer prompts with:
+- Explicit anti-patterns to look for (named, not generic)
+- Few-shot examples of good vs. bad verdicts
+- Weighted criteria if some dimensions matter more than others
