dot-iu-cutter v0.5 — Pre-Scale Index DDL Authoring GPT Review

Date: 2026-05-17 Reviewer: GPT Reviewed package: knowledge/dev/laws/dieu44-trien-khai/v0.5-pre-scale-index-ddl-authoring/

Verdict

v0_5_pre_scale_index_ddl_authoring: PASS
agent_behavior: PASS_CORRECT
authoring_only_boundary: respected
nothing_executed: true
index_execution_allowed_now: false
production_execution_allowed_now: false
bulk_cut_allowed_now: false
cat_hien_phap_allowed_now: false

The Agent completed the index-only DDL authoring phase correctly. The package contains the expected 5 documents, covers exactly the 7 GPT-approved hot paths, preserves the authoring-only boundary, and correctly defers dry-run / production execution to a separate sovereign cycle.

D-2 ruling — partial vs full indexes

D_2_partial_vs_full: APPROVED_PARTIAL_FOR_NULLABLE_REFS

Approved index strategy:

full_btree_indexes:
  - idx_dbe_status_emitted_keyset on decision_backlog_entry(status, emitted_at, entry_id)
  - idx_me_source_doc_ref on manifest_envelope(source_doc_ref)
  - idx_rd_manifest_id on review_decision(manifest_id)
  - idx_vr_change_set_id on verify_result(change_set_id)
partial_btree_indexes:
  - idx_ccs_dbe_id on cut_change_set(decision_backlog_entry_id) WHERE decision_backlog_entry_id IS NOT NULL
  - idx_dps_xref_cs on dot_pair_signature(cross_reference_change_set_id) WHERE cross_reference_change_set_id IS NOT NULL
  - idx_dps_xref_vr on dot_pair_signature(cross_reference_verify_result_id) WHERE cross_reference_verify_result_id IS NOT NULL

Reason: the expected runtime predicates are equality lookups with non-null bind values, so the partial predicates are semantically aligned and avoid indexing the large NULL fraction. Correctness is equivalent to full btree here; the partial form is preferred for size and write overhead.

D-5 ruling — production command model

D_5_production_command_model: DEFERRED_TO_SEPARATE_SOVEREIGN_CYCLE

No production index execution is authorized by this review. The next index step, if chosen, must be a separate phase with explicit dry-run, command review, sovereign approval, and post-run structural verification.

Assessment

The package satisfies the required boundaries:

index_only: true
additive_only: true
no_table_column_constraint_trigger_function_RLS_default_privilege_change: true
no_data_DML: true
no_label_registry: true
no_vector_NoSQL: true
no_code_change: true
no_git_commit: true
production_CIC_artifact: true
rollback_clean: true
structural_verification: true

The verification plan is especially important: it correctly avoids brittle pg_get_indexdef() string equality and uses catalog-level assertions instead. This preserves the lesson from prior false-negative verification issues.

Next routing decision

Two valid routes now exist:

Route A — continue accepted sequencing

Open:

next_phase: v0_5_pre_scale_index_ddl_dry_run_and_production_command_review
nature: dry_run_first_then_command_review

Purpose:

• execute the 7 indexes only in an isolated restored environment first;
• verify structural gates V-1…V-8 and A-1…A-5;
• prepare but do not self-execute production commands;
• if dry-run PASS, route to GPT/User for sovereign production approval.

Route B — broader user-directed architecture phase

Open:

next_phase: v0_5_constitution_hardtest_and_information_unit_factory_master_plan
nature: design_only

Purpose:

• design the full production information-unit factory around the Constitution hardtest;
• include ingestion, source registry, checksum/versioning, canonicalization grammar, label/metadata registry, SQL/NoSQL projection, volume harness, and staged rollout;
• keep all execution forbidden.

GPT recommendation

Given the user’s latest strategic directive, choose Route B first.

Reason: the index package is now ready, but the user’s larger goal is not only index readiness; it is making Cắt hiến pháp become a reliable end-to-end production operation. The master plan should sequence indexes as a prerequisite, but also prevent the team from optimizing one layer while leaving source authority, ingestion, canonical grammar, label registry, and projection strategy under-designed.

Forbidden until separately authorized

forbidden:
  - execute index DDL
  - run production CIC
  - run CUT_VERIFY
  - cat_hien_phap_execution
  - second_production_IU
  - bulk_cut
  - schema_migration
  - label_registry_creation
  - vector_NoSQL_integration
  - code_change
  - deploy_or_restart

Directive to Agent if user approves Route B

Open a design-only phase:

phase: v0_5_constitution_hardtest_and_information_unit_factory_master_plan
output_path: knowledge/dev/laws/dieu44-trien-khai/v0.5-constitution-hardtest-design/

The Agent must design only. It must not execute CUT/VERIFY, index DDL, schema migration, label registry creation, code changes, deploy/restart, or vector/NoSQL integration.
