dot-iu-cutter v0.1 — HB-02 X-4 Đ24 Enum Ratification / Lookup Readiness Closure

Date: 2026-05-15 Status: HB-02 CLOSURE RECORD — closed_with_notes Trigger: GPT review of HB-06 returned PASS (2026-05-15). User has explicitly authorized batch closure of HB-01, HB-02, HB-03, HB-04. Scope: CLOSURE RECORD ONLY. No code, no DDL, no SQL, no lookup table mutated, no migration, no PG mutation, no Directus mutation, no Qdrant/vector mutation, no backup, no snapshot, no dry-run, no execution.

1. Scope

HB-02 binds the enum implementation strategy decision X-4 for dot-iu-cutter v0.1 P0. The decision selects Đ24 lookup-FK as the enum implementation strategy and records which enum groups are ratified / ready at this point.

hb_02_scope:
  in_scope:
    - record X-4 selected approach acceptance (Đ24 lookup FK)
    - record ratified / ready enum groups for P0
    - record outstanding enum sets that still need ratification before execution
    - record authority attribution (Đ24 + Đ44)
  not_in_scope:
    - populate any lookup table
    - create the lookup tables in PG
    - issue final Đ24 ratification text for outstanding enum sets (those issuances live as separate ratification artefacts under ratification/ produced in future sessions)
    - mutate any vocabulary registry

This is enum strategy + readiness ratification, not lookup-table population. The decision X-4 is now accepted; the operational lookup-table population is an execution-phase task that does not block planning closure of HB-02.

3. Decision Recorded

decision_id: HB-02
cross_cutting_decision_resolved: X-4
selected_option: dieu24_lookup_table_fk

strategy_decision:
  enum_field_implementation: Đ24-managed lookup table FK (text or uuid key per Đ24 convention)
  no_pg_native_enum_type: TRUE
  no_check_constraint_only: TRUE
  representation:
    - lookup tables live in cutter_governance schema (or Đ24-owned vocabulary schema; final at execution-phase DDL authoring)
    - parent table enum field carries the FK value
    - cross-family alignment: same vocabulary used across P0 items where shared (e.g., verdict reused between verify_result and review_decision)

ratified_or_ready_enum_groups_for_P0 (already Đ24-bound):
  section_type_unit_kind:

4. Authority / Sign-Off

authorities_signing:
  primary_signers:
    - Đ24 (vocabulary owner) — ratifies enum strategy + already-ratified groups
    - Đ44 (family registry custodian) — accepts cross-family alignment per Đ44 family pattern
  secondary_signers:
    - GPT (policy reviewer; PASS upstream on cross-cutting register and X-4 recommendation)
    - User / anh Huyên (sovereign authority)
    - Opus / Agent (record-keeping side)

what_each_authority_accepts:
  Đ24:
    - lookup FK strategy as the enum implementation pattern for P0
    - already-ratified group set
    - outstanding sets routed to separate Đ24 ratification sessions before execution
  Đ44:
    - cross-family alignment (e.g., verdict shared between verify_result and review_decision)
    - lookup-table family placement in cutter_governance (per HB-01) OR Đ24-owned vocabulary schema — Đ24 decides final location
  GPT:
    - cross-cutting register §3.5 recommendation matches the closure
  User / anh Huyên:
    - sovereign acceptance per the explicit prompt

5. Acceptance Criteria

acceptance_criteria_for_hb_02:
  x_4_strategy_accepted:
    status: ACCEPTED (Đ24 lookup FK)
  already_ratified_groups_enumerated:
    status: ENUMERATED (section_type, unit_kind, body_source_policy, risk_class, collision_status, authority values, axis_1_drift_unit value, P0 event/signal names)
  outstanding_sets_recorded_as_pending_separate_ratification:
    status: ENUMERATED (cut_change_set/cut_change_set_affected_row/dot_pair_signature/verify_result/review_decision/decision_backlog_entry sets)
  signing_attribution_recorded:
    status: ATTRIBUTED (Đ24 + Đ44 primary; GPT + User + Opus/Agent secondary)
  no_lookup_table_populated:
    status: confirmed
  no_pg_mutation:
    status: confirmed
hb_02_acceptance_state: ALL SIX criteria satisfied; closure_with_notes

6. Downstream Effects

downstream_effects_of_hb_02_closure:
  P0_step_FK_references:
    note: every P0 step (Step 1 through Step 6) references at least one Đ24 lookup FK; design-level FK identity is now bound by strategy
    status_change: design-level confidence increased; execution-phase still gated by outstanding lookup-table population
  first_DDL_of_every_P0_step:
    note: first DDL cannot occur until lookup tables exist; HB-02 confirms strategy, not population
    status_change: pre-execution gate intact

operational_followup_remaining (NOT a blocker; tracked as a parallel operational task):
  - per-enum Đ24 ratification for each outstanding set listed in §3 (separate Đ24 sessions)
  - operational lookup-table population once Đ24 ratifies each set
  - both tasks fold into execution-phase DDL authoring; do NOT block planning closure of HB-02

no_other_HB_directly_unlocked_by_HB_02: HB-02 is independent and parallel to the critical path

what_HB_02_does_NOT_do:
  - create any lookup table
  - populate any lookup table
  - issue Đ24 ratification text for outstanding sets (those issuances live in separate ratification artefacts produced in future Đ24 sessions)
  - bind the lookup-table schema placement to cutter_governance vs Đ24 vocabulary schema (Đ24 decides final location at ratification time)
  - choose key form (text vs uuid) for the lookup primary key (Đ24 decides at ratification time)

7. Status

HB_02_status: closed_with_notes
HB_02_closure_authority: Đ24 + Đ44 (per cross-cutting register §3.5 + user prompt 2026-05-15)
HB_02_closure_signers:
  - Đ24 vocabulary owner (primary)
  - Đ44 family registry custodian (primary)
  - GPT (policy reviewer)
  - User / anh Huyên (sovereign authority)
  - Opus / Agent (record-keeping)

execution_authorized: false
implementation_allowed: false
ddl_allowed: false
migration_allowed: false

notes_carried_forward:
  - lookup readiness is CONCEPTUAL: strategy bound; per-enum Đ24 ratification of outstanding sets pending; operational population deferred to execution-phase DDL authoring
  - lookup-table schema placement (cutter_governance vs Đ24 vocabulary schema) deferred to Đ24 at ratification time
  - key form (text vs uuid) for lookup primary key deferred to Đ24 at ratification time
  - axis_1_drift_unit value canonical_token already bound at X-A; enum membership remains {byte, line, ast_node, canonical_token}
  - no lookup table created or populated by this closure
  - no PG mutation by this closure
