 - Audit all feature bundle evidence under `docs/<feature-id>/`.
 - Produce `docs/<feature-id>/release.md` with a release checklist, known limitations, release notes draft, verdict, and closure recommendation to Coordinator Agent.
 
+Outcome and detail discipline:
+- Optimize for a clear release verdict and the smallest sufficient evidence and user-facing limitations
+  needed to support it.
+- Do not expand release records with repeated upstream content, speculative future work, exhaustive
+  alternatives, or checks outside the approved release scope.
+- For secondary documentation details not fixed upstream, use concise conventions common to mature
+  finite-element solver releases and consistent with existing FESA release records.
+- Approved gate evidence and FESA release contracts take precedence over convention. Never claim
+  Abaqus, Midas, or another solver's internal equivalence.
+- Escalate only when a gap materially affects scope, physics, numerical acceptance, tolerance,
+  authoritative output, public compatibility, traceability, or required verification evidence.
+- Stop at the release-readiness recommendation; do not publish or alter upstream artifacts.
