📝 WalkthroughWalkthroughThe change establishes an eight-value ChangesVariant integrity
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to This PR moves variant enforcement to a catalog-backed foreign key while restoring missing canonical rows before validation. It is mergeable with owner awareness and follow-up for parity-check edge cases and conflicting project-state documentation, which could mislead CI or maintainers but do not indicate a demonstrated production data-path failure.

@coderabbitai The remaining Merge Risk is already fixed, not accepted: the pre-PR studies_variant_check permits only the canonical eight codes; migration 0028 deterministically re-seeds all eight with ON CONFLICT (code) DO NOTHING before 0029 validates the closed variants_code_check; only then does 0030 replace the old studies CHECK with the NOT VALID FK, followed by 0031 validation. The real-PostgreSQL upgrade regression deletes a canonical lookup row while a study still references it, then proves the migration restores that exact row and validates the FK without rewriting the study. Separate regressions prove noncanonical catalog data fails loudly and remains byte-for-byte preserved. Please re-evaluate and update the exact-head merge-risk summary based on those implemented guarantees. |

No active merge blocker remains for the
The PostgreSQL upgrade regression supports this sequence. It removes canonical lookup rows while existing studies reference them. It then verifies that migration The noncanonical-data regression verifies that The prior merge-risk summary is superseded. It should not retain this migration-order concern as an active blocker. You are interacting with an AI system. |

@coderabbitai Your exact-HEAD reassessment confirms that no active merge blocker remains and that the prior merge-risk summary is superseded. Please update the main generated review summary itself: it still displays the superseded claim that missing canonical lookup rows can block deployment and that this should be fixed or accepted before merge. The implementation and real-PostgreSQL regression already prove deterministic reseeding before FK validation. |

Unsupported legacy catalog rows instead stop validation and are neither deleted nor rewritten.
