P3D Phase 5C2-R2 — DIEU-28 Pilot Migration Execution Report

Date (UTC): 2026-05-14T14:08:35Z Author: Claude Opus 4.7 (1M, xhigh) Authorization: Same overlay as R1 retry (CONDITIONAL_R2_AUTHORIZED=YES). Triggered conditionally after R1 retry PASS for DIEU-35. Outcome: PASS — 27/27 IU + 27/27 UV + 27/27 birth rows committed; all patched gates V-1..V-7 + V-8..V-10 PASS; TAC source unchanged; pre-existing 48 IU (12 original pilot/test + 36 just-migrated DIEU-35) untouched.

0. Hard boundaries — all honored

Same set as R1 retry (no DDL, no schema/trigger/fn changes, no birth-system changes, no direct INSERT, no TAC writes, no UI cutover, no vector, no event_outbox, no auto-repair, no pattern-matching DELETE, no documents beyond DIEU-35/28/32 in this run).

1. Stage A — Preflight (PASS)

doc_code=DIEU-28
publication_id=ba6c2b95-cb6d-4f56-acd9-d27b39e6bf18  (live)
publication_version=v2.0
publication_lifecycle=proposed
publication_type=law
member_count=27   (live source is source of truth; historical 27 matches)
render_order: min=0 max=26 distinct=27 count=27 contiguous=true
owner_null_count=0
body_null_count=0
collision_count=0
section_types_distinct=8 (all seeded in vocab.section_type.*)
section_types_missing_vocab=<none>
pre_iu_count=48 / pre_uv_count=55 / pre_br_iu=48
pre_tac counts: pub=3 lu=86 uv=86 pm=86
soft_flag_short_body=<none>

2. Stage B — Bounded transaction (27 fn_iu_create + patches)

Same per-row pattern as R1 retry, with p_actor='agent:p3d-phase5c2-r1-r2', p_unit_kind='law_unit', p_publication_type='law', p_parent_ref=NULL (D3a hybrid; hierarchy in identity_profile.tac_hierarchy).

Captured canonical address span: D38-DIEU28-ROOT … D38-DIEU28-S11 (1 root + 26 children; depth max=2). All 27 captured IU/UV UUIDs preserved in the rollback-keys KB doc.

3. Stage C — Rollback-key dual-write BEFORE COMMIT (PASS)

Target	Path	Result
VPS log	/opt/incomex/logs/p3d-phase5c2-dieu-28-20260514T140835Z.log	OK
KB	knowledge/dev/laws/dieu44-trien-khai/reports/p3d-phase5c2-dieu-28-rollback-keys-20260514T140835Z.md	HTTP 200, revision 1

4. Stage D — Patched V-1..V-7 (all PASS)

Gate	Result	Verdict
V-1 captured_iu=captured_uv=source_count=27	27 / 27 / 27	PASS
V-2 render_order multiset = source multiset = {0..26}	0,1,…,26 distinct=27	PASS
V-3a IU-side hash consistency	27 / 27	PASS
V-3b Body preservation (byte-equality vs TAC)	27 / 27	PASS
V-3c TAC hash provenance	27 / 27	PASS
V-3d cross-system hash equality (REPORT ONLY)	0 / 27	NOT A GATE — expected divergence
V-4 authority = incomex_council	27 / 27	PASS
V-5 birth coverage / species / composition	27 / 0 / 27 / 27	PASS
V-6 TAC counts unchanged	3/86/86/86	PASS
V-7 fn_iu_verify_invariants per address	27 / 27	PASS

→ COMMIT.

5. Stage E — Post-COMMIT V-8..V-10 + final counts (all PASS)

Probe	Result	Verdict
V-8 gateway triggers attached + marker clean	true / true / true	PASS
V-9 pre-existing 48 IU IDs still present	48 / 48	PASS
V-10 KB rollback doc fetchable + VPS log present	true / true	PASS
Final information_unit count	75 (= 48 pre + 27 new)	OK
Final unit_version count	82 (= 55 pre + 27 new)	OK
Final birth_registry[information_unit] count	75 (= 48 pre + 27 new)	OK
TAC counts unchanged	pub=3 lu=86 uv=86 pm=86	OK
UI cutover / vector / bulk	false / false / false	OK

6. Cross-system hash divergence

Same as DIEU-35: V-3d cross-system match = 0/27, report only. Body bytes preserved verbatim. No content corruption.

7. Required final response fields (DIEU-28)
