Files reviewed: Combined P0-6 + P0-5 remainder design package
Scope: Design review only. No DDL, no mutation, no dry-run, no production action.

3. Open Decisions Ratified

Review decision family

RD_1_manifest_id_reference: in_schema_FK_to_manifest_envelope
RD_2_unit_level_reference: nullable_composite_FK_to_manifest_unit_block
RD_3_re_review_chain: in_schema_self_FK
RD_4_verdict_enum: cutter_local_text_v0_2_D24_alignment_note_only
RD_5_findings_completeness: all_10_required_for_PASS_as_application_rule_v0_2
RD_6_reviewer_independence: application_layer_v0_2_no_PG_trigger

Decision backlog remainder

DBH_1_history_granularity: status_version_plus_critical_fields
DBH_2_change_kind_enum: cutter_local_text_v0_2
DBD_1_dependency_cycle_detection: application_layer_v0_2_no_PG_trigger
DBD_2_dependency_kind_enum: cutter_local_text_v0_2
DBS_1_sweep_trigger_kind_enum: cutter_local_text_v0_2

Batch-level enum implementation

BATCH_1_enum_implementation: text_columns_with_documented_allowed_values_for_v0_2
not_selected_for_v0_2:
  - PG_enum
  - D24_lookup_FK
reason: avoid_extra_tables_or_cross_family_FKs_in_final_empty_table_batch
future_path: D24_lookup_alignment_can_be_revisited_after_v0_2_live

Note: This intentionally overrides the Agent lean for BATCH-1. The DDL authoring package must not create Đ24 lookup tables or lookup FKs.

4. Binding DDL Authoring Constraints

schema: cutter_governance
new_tables: 4
empty_tables: true
allowed_FKs:
  - in_schema_family_FKs_only
allowed_soft_refs:
  - cross_family_uuid_or_text_refs
forbidden:
  - cross_schema_FK
  - PG_trigger
  - PG_enum
  - new_lookup_table
  - D24_lookup_FK
  - seed_INSERT
  - backfill
  - production_CUT_VERIFY

CHECK constraints should be avoided unless the DDL authoring package proves they are purely structural and do not encode policy. Default posture: no CHECK constraints.
