1. Verdict

phase_alpha_ddl_authoring_r2_status: PASS
agent_revision_needed: false
DDL_execution_allowed_now: false
dry_run_lane_allowed_after_explicit_prompt: true
production_migration_allowed: false
reason: r2_fixes_authority_default_backfill_semantics

The r2 DDL package is accepted. The r1 blocking issue is resolved.

2. Confirmed r2 Fix

The authority column sequence is now correct:

public_tac_logical_unit_authority:
  step_1: ADD COLUMN authority text  # no default
  step_2: UPDATE from lifecycle_status mapping
  step_3: ALTER COLUMN authority SET DEFAULT 'draft'

sandbox_tac_logical_unit_authority:
  step_1: ADD COLUMN authority text  # no default
  step_2: no backfill
  step_3: ALTER COLUMN authority SET DEFAULT 'draft'

Expected dry-run verification remains:

public.tac_logical_unit.authority:
  draft: 86
  enacted: 0
  runtime: 0
  null: 0
sandbox_tac.logical_unit.authority:
  null: 76

3. Accepted Remaining Posture

single_transaction: accepted
idempotency_guards: accepted
fn_tac_birth_gate_lu_updated_at_side_effect: accepted_for_dry_run
canonical_address_format_version_NOT_NULL_DEFAULT: accepted
alias_table: cutter_governance.canonical_address_alias
cross_schema_FK: none
CHECK_constraint: none
sandbox_alias_table: none
identity_profile_cleanup: deferred

The updated_at bump on 86 public rows must be measured and explicitly verified in dry-run. It remains acceptable only if all other verification checks pass.

4. Next Gate

Open the Phase α dry-run lane with a separate explicit prompt. The dry-run package must first extract the executable r2 SQL body from §2 of the .sql.md file and freeze its SHA256 before execution.

next_step: phase_alpha_dry_run_lane
required_first_action: extract_r2_sql_body_and_capture_sha256
production_execution_allowed: false

5. Status

ready_for_dry_run_prompt: true
ready_for_production_prompt: false
