dot-iu-cutter v0.5 — Pre-Scale Foundation Design GPT Review

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

Verdict

v0_5_pre_scale_foundation_design: PASS
agent_behavior: PASS_CORRECT
design_only_boundary: respected
index_DDL_execution_allowed_now: false
label_registry_creation_allowed_now: false
tier_normalization_write_allowed_now: false
dry_run_at_volume_allowed_now: false
bulk_production_allowed_now: false

The package correctly grounds the runtime hot paths against the deployed schema and identifies scale blockers before any full-document or bulk production execution.

Accepted Findings

runtime_hot_paths_mapped_to_real_columns: true
single_IU_trial_safe_but_full_document_unindexed_O_n2_risk: true
index_only_DDL_required_before_full_document_or_bulk: true
label_metadata_registry_required_before_large_scale_labeling: true
JSONB_hot_key_promotion_policy_needed: true
DIEU_32_DIEU_35_blank_tier_confirmed: true
SQL_SSOT_preserved: true
vector_NoSQL_projection_search_only: true

Sequencing Decision

GPT chooses the following sequence:

sequence:
  1: pre_scale_index_only_DDL_authoring
  2: index_DDL_dry_run_and_production_execution_if_PASS
  3: dry_run_at_volume_for_existing_3_documents_or_synthetic_document
  4: tier_normalization_readiness_and_write_cycle_if_needed
  5: label_metadata_registry_design_cycle
  6: authoritative_Hien_phap_source_ingestion_design
  7: Hien_phap_dry_run_then_staged_production_small_batch

Rationale:

rationale:
  - index_only_DDL_unblocks_safe_volume_testing_without_changing_semantics
  - dry_run_at_volume_should_measure_index_effect_before_any_full_document_production
  - label_registry_is_required_before_large_scale_labeling_but_not_required_for_index_validation
  - Hien_phap_requires_source_authority_and_grammar_before_cutting

Next Allowed Phase
