04 - DOT No-Overwrite / PG-Native Authority

Verdict

CHECK_D_DOT_NOOVERWRITE_HOLD_NEEDS_IDENTITY_AND_PHASE_FIX

The corrected principle is valid: DOT/source scans are diagnostic only; PG catalog ownership, ACL, dependency, sealed manifests, and hashes are final authority.

Two blueprint issues remain:

1. G-DOT-NOOVERWRITE refers to the QT001 writer gateway as owned by qt001_cp_owner, but the identity and ownership phase of the live writer/gateway are not unambiguous across S15 before S16 owner/ACL cutover. T1 must identify the exact gateway object(s), old/new owner at each phase, and phase-specific expected guard result.
2. The S00 name-pattern-derived set used as binding authority independently violates PG-native-driven discipline, even though DOT source scanning itself is diagnostic.

Required T1 fix: make every protected object identity and expected owner phase-explicit; no guard may assume the post-S16 owner state at S15.
