§2 — BR-4 Closure Summary

selected_rule: Candidate B — Derive from lifecycle_status mapping

mapping (ratified):
  draft_only → draft
  active     → enacted
  retired    → enacted

interpretation (ratified by GPT):
  authority represents source authority class;
  lifecycle_status represents operational lifecycle;
  therefore retired → enacted is acceptable because retired enacted units
  remain sourced from enacted authority while retirement is carried by lifecycle_status.

current_86_rows_expected_backfill_result: all → authority='draft' (because 100% are lifecycle_status='draft_only')

phase_alpha_column_policy:
  authority nullable in Phase α
  authority DEFAULT 'draft' for new writes
  NOT NULL constraint DEFERRED until Phase β write hook lands

sandbox_tac:
  mirror column in Phase α (same default)
  no sandbox backfill in Phase α (deferred to Phase β alongside production write hook)

§3 — BR-5 Closure Summary

ratified_version_string: canonical-address-v1
short_form_allowed: cav1
rejected_alternative: d38-v1

grammar (ratified):
  D{doc}-DIEU{N}-{S{seg}|ROOT}[-P{n}][-{n}]

storage_rules (ratified):
  - ASCII only
  - hyphen-separated
  - case-sensitive (upper-case canonical)
  - no whitespace

storage_display_decoupling (ratified):
  storage form remains D38-DIEU28-S2-P1 (ASCII)
  display renderer may later show human form such as Đ28 §2.1 (presentation-layer; out of v0.2 P0 scope)

non_law_artifact_format: DEFERRED to future Đ24 follow-up (NOT in v1)

phase_alpha_column_policy:
  add public.tac_logical_unit.canonical_address_format_version text NOT NULL DEFAULT 'canonical-address-v1'
  mirror on sandbox_tac.logical_unit with same default
  all 86 + 76 rows backfill automatically at column-add time via DEFAULT

§5 — Can Phase α Design Start?

phase_alpha_design_can_start_after_GPT_review_of_these_closures? YES

precondition_for_start:
  - explicit GPT or User prompt authorizing Phase α design authoring
  - prompt MUST reference one or more of:
    a) this closure report
    b) BR-4 closure record
    c) BR-5 closure record

phase_alpha_design_scope_when_authorized:
  add columns on public.tac_logical_unit:
    - authority text NULL (DEFAULT 'draft'; backfill rule per BR-4)
    - canonical_address_format_version text NOT NULL DEFAULT 'canonical-address-v1'
  add table:
    - canonical_address_alias (placement: tac OR cutter_governance schema — Phase α design decides)
  mirror on sandbox_tac.logical_unit:
    - same additive columns (per BR-7 Option II)
  do NOT extend to sister tables (per Option D scope restriction)
  do NOT alter existing canonical_address column on tac_logical_unit (preserve as SSOT per Option D)
  do NOT touch event_outbox / information_unit / unit_edit_draft / iu_notification_event / event_pending / birth_registry

after_design_authoring_(separate_subsequent_phases):
  - HB-equivalent dry-run authoring + execution
  - blocker closure pass
  - final readiness review
  - command-review package
  - explicit production execution prompt
  - production execution (separate session)
  - GPT ratification of v0.2 execution report

agent_self_advance_to_phase_alpha_design: PROHIBITED
each_phase_terminates_at_GPT_review_or_explicit_prompt: TRUE

§6 — Recommended Next Action

recommended_next_action: GPT reviews the BR-4 closure + BR-5 closure + this consolidated closure report; then issues explicit prompt authorizing Phase α design authoring

in_parallel_(non_blocking_for_phase_alpha_DDL):
  - author or read the BR-6 split/merge metadata propagation TD
    path: knowledge/dev/laws/dieu44-trien-khai/backlog/td-p1-split-merge-metadata-propagation-gap-2026-05-15.md
  - BR-6 closure can land on its own track; it gates P0-2 design which is downstream of Phase α
