FLOOR (deterministic, pharn/floor/check-plan-lessons.mjs): /pharn-dev-grill is the FIRST stage that did NOT author the field to re-verify it — the PLAN's applied_lessons must still be present, well-formed (`none` | `[L<n>…]`), and every cited id must still resolve to a `## L<n> ` heading in canon, else the declaration is stale → a deterministic RED. Before this, the field was self-attested by the stage that wrote it. ADVISORY: the interrogation itself — surface gaps, unstated assumptions, missing guarantee-audit reductions, untested axes — emitted as an advisory grill-log (GRILL.md) of finding-shape findings + a verdict. The interrogation NEVER blocks; the lessons-declaration RED is the ONLY deterministic stop. '/pharn-dev-grill produced a GRILL.md' guarantees the declaration held — it NEVER means 'the plan is good', and NEVER means the lessons were genuinely APPLIED (P0)."
