dot-iu-cutter v0.2 — P0-2 Manifest Design GPT Review

Date: 2026-05-16
Reviewer: GPT
Files reviewed: P0-2 manifest design master, envelope design, unit block design, BR-6 invariant integration, GOV register, risk/dry-run note, design report
Scope: Design review only. No DDL, no mutation, no dry-run, no production action.

1. Verdict

p0_2_manifest_design_status: PASS
agent_revision_needed: false
risk_class_estimate: STANDARD
GOV_1_status: ratified_with_notes
GOV_2_status: ratified_with_notes
GOV_3_status: ratified_with_notes
P0_2_DDL_authoring_allowed_after_explicit_prompt: true
P0_2_dry_run_allowed: false
production_migration_allowed: false

The P0-2 logical manifest design is accepted. GOV-1, GOV-2, and GOV-3 are ratified at design level, unblocking DDL authoring. DDL execution remains forbidden.

2. Accepted Design

manifest_envelope:
  operation_kind: [first_cut, split, merge]
  status_lifecycle: draft_to_under_review_to_accepted_to_enacted_plus_rejected_withdrawn_superseded
  escalation_ref: soft_reference_to_decision_backlog_entry
  cut_change_set_ref: soft_reference_to_cut_change_set
  superseded_by_envelope_id: soft_self_reference
  owner_reviewer_metadata: included

manifest_unit_block:
  primary_identity: [envelope_id, unit_local_id]
  in_schema_FK: envelope_id_to_manifest_envelope_only
  block_role: [origin, result]
  source_span: mandatory
  render_order: required
  target_unit_id: soft_uuid_reference_to_tac_logical_unit
  proposed_canonical_address: proposal_only_never_write_SSOT
  proposed_authority: proposal_only_never_write_SSOT
  candidate_edges: jsonb_intent_only
  payload_summary: jsonb
  report_summary: jsonb

3. Binding Constraints

cross_schema_refs: soft_uuid_only
pg_FKs: only_manifest_unit_block_envelope_id_to_manifest_envelope
pg_CHECK_trigger_DEFAULT: avoid_in_P0_2
manifest_alias_direct_coupling: none
edge_tables: none
empty_at_create: true
rollback_model: drop_empty_tables
split_merge_execution: P1_deferred

4. GOV Decisions Ratified

GOV-1 — address-coining rule

selected_option: O3_hybrid
split_rule: extend_original_address_tail
merge_rule: new_sequence_address
status: ratified_with_notes

Rationale: split preserves lineage; merge creates a synthesized result that should not pretend to be a direct continuation of one origin.

GOV-2 — authority inheritance

selected_option: O1_demote_to_draft
rule: all_split_merge_result_blocks_start_as_draft
status: ratified_with_notes

Rationale: topology-changing operations must not silently carry enacted authority. Re-enactment/review can restore authority later.

GOV-3 — manifest ↔ alias linkage

selected_option: O1_event_backed_no_coupling
rule: no_alias_ref_column_in_P0_2_manifest
status: ratified_with_notes

Rationale: alias emission is a P1 enactment behavior derived from operation_kind, block_role, target_unit_id, and proposed_canonical_address. P0-2 should not couple empty manifest tables to alias rows.

5. BR-6 Invariants Confirmed

INV_1: canonical_address_immutable_new_addresses_alias_trail_mandatory
INV_2: no_authority_escalation_without_re_enactment
INV_3: format_version_inherited_no_downgrade
INV_4: topology_change_emits_alias_rows_at_P1
INV_5: split_merge_review_gated
INV_6: metadata_mutation_through_cut_change_set_and_verify_result_only

6. Gate Effect

P0_2_DDL_authoring_can_start: true_after_explicit_prompt
P0_2_DDL_freeze_blockers: none_known_after_this_review
P0_2_dry_run_can_start: false
P0_2_production_execution_can_start: false

Agent may now author a P0-2 DDL package for review, but must not execute it.

7. Status

ddl_written_by_this_review: false
mutation_performed: false
dry_run_started: false
production_migration_allowed: false
