Verdict

Phase 5A post-disambiguation dry-run PASS is accepted.

Agent execution was correct. No additional read-only rerun is required.

Accepted evidence

• no_mutation_performed=true
• gate0_all_passed=true
• resolved_field_map_complete=true
• g1_to_g11_attempted=true
• old_concept_references_present=false
• publication_metrics_available=true
• provenance_projection_available=true
• rollback_sizing_available=true
• nesting_evidence_available=true
• nesting_max_depth=2
• address_collision_count=0
• scale_brittleness_self_audit_passed=true

Key evidence:

• TAC source: 86 logical units, 86 versions, 3 publications.
• Per publication: DIEU-28 = 27, DIEU-32 = 23, DIEU-35 = 36.
• Per-publication render order: contiguous, no duplicates.
• Nesting: 3 roots, 83 children, max depth 2.
• Parent column: parent_id resolved through semantic registry.
• Target parent column: parent_or_container_ref resolved.
• fn_iu_create supports p_parent_ref.
• Collision count: 0.
• Hash divergence confirmed: TAC hash differs from IU fn_content_hash(body); IU must recompute and preserve TAC hash as provenance.
• Structured provenance carrier: unit_version.content_profile jsonb exists and is empty on current rows.
• Birth gate fields: satisfied at column level.
• Species/composition evidence: atom and molecule candidates exist, but no species decision locked.

GPT strategic recommendation

For the next design step, use the following working recommendation:

Nesting strategy: D3 HYBRID
IU rows remain atomic units; TAC parent-child structure is preserved as relationship metadata/edges, not as parent IU containment at migration time.

Reason:

1. D3 preserves structure better than pure flattening.
2. D3 avoids forcing parent IU rows into mixed compound/molecule species before the species system is fully governed.
3. D3 keeps one logical information piece = one IU = one vector boundary clean.
4. D3 aligns with future typed-edge/impact-analysis packs.
5. D3 has lower species/composition complexity than D1 and less information loss than D2.

This is still a design recommendation, not an executed migration decision.

Recommended pilot

Use DIEU-35 as the pilot candidate for design planning because it has the highest live diversity count and exercises more section types.

Pilot candidate: DIEU-35
Reason: 36 members, 12 section types, nesting depth 2, render_order valid.

This is a recommended pilot for the next design/executable prompt, not yet a migration execution approval.

Next phase

Open:

P3D_PACK1_PHASE5B_HYBRID_NESTING_SPECIES_AND_PILOT_MIGRATION_DESIGN

Mode:

DESIGN + EXECUTION-PROMPT-DRAFT ONLY

Phase 5B must not run migration yet. It should create the design and the implementation prompt draft for GPT/User review.

Phase 5B scope

Phase 5B should design:

1. D3 hybrid nesting strategy.
2. Species/composition strategy after D3.
3. Whether a new law-unit species is needed under QT-005.
4. QT-001 backfill strategy for current IU rows only if mapping is approved.
5. Pilot migration plan for DIEU-35.
6. Exact-key rollback model.
7. Post-implementation design requirement.

Hard boundaries

• No DB write by Opus.
• No agent dispatch by Opus.
• No migration.
• No seed.
• No backfill.
• No DDL.
• No function/trigger patch.
• No species creation without QT-005 design.
• No hardcoded row counts as gates.
• All future executable prompts must keep semantic registry discipline.
