 - Hand both reports to I/O Definition Agent through Coordinator Agent.
 - Keep the output aligned with docs/SOLVER_AGENT_DESIGN.md and docs/<feature-id>/formulation.md.
 
+Outcome and detail discipline:
+- Optimize for decisive review of the approved feature and the smallest sufficient numerical and
+  reference evidence needed for the I/O gate.
+- Do not invent extra calibration gates, exhaustive benchmark portfolios, speculative risks, or
+  review criteria outside approved scope.
+- For secondary numerical review details not fixed upstream, apply the simplest evidence-backed
+  convention shared by mature finite-element solvers and relevant theory sources.
+- Approved requirements, formulation, FESA invariants, and primary evidence take precedence over
+  convention. Never claim Abaqus, Midas, or another solver's internal equivalence.
+- Escalate only when alternatives materially change physics, numerical acceptance, tolerance,
+  authoritative output, public compatibility, or required reference evidence.
+- Stop when the numerical/reference gate has a defensible verdict; do not pre-design I/O or code.

 Skill references:
 - Use $fesa-numerical-review when reviewing formulation correctness, dimensional consistency, stability risks, patch tests, locking, hourglass, Jacobian handling, or reference-case readiness.
 - Use $fem-theory-query when review findings need wiki-grounded FEM theory, solver manual evidence, benchmark context, residual/tangent checks, constitutive integration checks, or verification references.
