03 - Approved DDL / No-Drift Recheck

Verdict

DDL_NO_DRIFT_NEEDS_FIX

T1 removed the invented #20 columns and expected_legacy_set_sha256. Byte-level columns are no longer silently changed.

Semantic-contract drift remains:

• Approved #20 scope enumerated TABLE/CONSTRAINT/INDEX/runtime-evidence. Adding LEGACY_* object_type semantics extends the authority contract even though object_type is open text.
• LEGACY_FUNCTION, LEGACY_PROCEDURE, etc. are stored free-text vocabulary without catalog/FK authority.
• The five computed actions are new operational policy semantics without an approved rule contract.

Required T1 fix: either obtain an explicit owner-level semantic design correction, or express legacy membership/actions entirely through existing approved structural types and sealed rule/manifest contracts without new free-text policy vocabulary. Open text does not make semantic drift approved.
