agent_revision_needed: false
verification: 16_of_16_PASS
rollback_test: PASS

2. Confirmed Evidence

dry_run_env: pg-dry-run-v0.2-phase-alpha-2026-05-16
r2_sql_sha256: 65533e0564ee45625b43bff383252ec03f20e284a5cc506d78e1079d6f893fe3
pre_backfill_checks: 3_of_3_PASS
post_ddl_verification: 16_of_16_PASS
rollback_test: PASS
production_untouched: true

Critical r2 proof:

public.tac_logical_unit.authority:
  draft: 86
  enacted: 0
  runtime: 0
  null: 0
sandbox_tac.logical_unit.authority:
  null: 76
updated_at_bump:
  changed_rows: 86_of_86
  interpretation: expected_backfill_trigger_effect

The updated_at bump confirms the Step 3 backfill actually ran. This is the decisive evidence separating r2 from the rejected r1 pattern.

3. Notes Accepted

N_1_updated_at_bump: accepted_expected_side_effect
N_2_pg_dump_restrict_nonce_noise: accepted_not_schema_delta
N_3_pg_dump_inlined_columns: accepted_verified_by_column_checks

None of the notes are blockers.

4. Decision on Next Gate

Do not skip command review. Even though Phase α is smaller than v0.1, it updates 86 production rows and bumps updated_at; therefore the production command package must be reviewed separately.

command_review_required: true
production_execution_prompt_allowed_before_command_review: false

5. Status

ready_for_phase_alpha_command_review_package: true
production_migration_allowed: false
