Verdict

Status: ACCEPT_R1_ROLLBACK__PATCH_V3_SPEC__AUTHORIZE_R1_RETRY_AND_CONDITIONAL_R2

Agent execution is accepted. Rollback was correct. The failure was caused by an over-strict validation spec, not by migration corruption.

Accepted facts

• Authorization was confirmed.
• Preflight PASS.
• 36 fn_iu_create calls succeeded in one transaction.
• 36 IU + 36 UV + 36 birth rows were created transiently.
• Identity/content profile patches succeeded via allowed marker.
• Rollback keys were dual-written to KB + VPS log before COMMIT.
• V-1, V-2, V-4, V-5, V-6, V-7 PASS.
• V-3a PASS: IU-side content_hash = fn_content_hash(body) for 36/36.
• V-3b FAIL: TAC content_hash != IU fn_content_hash(body) because hash schemes differ.
• Agent rolled back per prompt.
• Post-rollback verification confirms zero residue.
• TAC source and pre-existing 12 IU pilot/test rows are untouched.

V-3 spec patch

Old V-3 was too strict:

unit_version.content_hash = fn_content_hash(body) = tac_unit_version.content_hash

This incorrectly assumed TAC and IU use the same hash algorithm over the same input.

New V-3:

V-3a IU-side hash consistency: unit_version.content_hash = fn_content_hash(unit_version.body) — REQUIRED GATE.
V-3b Body preservation: migrated unit_version.body must equal source tac_unit_version.body byte-for-byte/text-for-text — REQUIRED GATE.
V-3c TAC hash provenance: source tac_unit_version.content_hash must be preserved in unit_version.content_profile.src_content_hash — REQUIRED GATE.
V-3d Cross-system hash equality: NOT A GATE unless TAC hash algorithm is formally harmonized in a future pack.

Rationale:

• IU storage integrity belongs to IU hash function.
• TAC hash is legacy/source provenance unless its algorithm is recovered and ratified.
• Coupling migration success to undocumented TAC hash algorithm violates evidence-first design and blocks useful progress.

R1 retry decision

Authorize R1 retry for DIEU-35 under patched V-3.

r1_retry_authorized=true
scope=DIEU-35_ONLY_36_ROWS
ui_cutover_allowed=false
vector_work_allowed=false
bulk_migration_allowed=false

Conditional R2 decision

To accelerate safely, authorize conditional R2 in the same Agent session only if R1 retry PASS and each R2 publication independently passes the same gates.

R2 scope:

DIEU-28 v2.0 — expected current live source count must be discovered, historical expectation 27 is reference only.
DIEU-32 v1.1 — expected current live source count must be discovered, historical expectation 23 is reference only.
Each publication must be migrated in a separate transaction.

R2 conditions:

• Run R0-like mapping/gate generation live for each publication immediately before its transaction.
• No hardcoded counts; historical counts are reference only.
• 0 collisions required.
• 0 missing owner/body/vocab required.
• contiguous render_order required unless explicitly explained and accepted as source truth.
• exact-key rollback keys dual-written before COMMIT for each publication.
• same patched V-3 semantics.
• if any publication fails preflight or in-transaction validation, rollback/skip that publication and report; do not attempt bulk rescue.
• no UI cutover, no vector, no Directus/Nuxt changes.

Strategic automation direction

User’s target is not manual conversion of one pre-cut document. The target is:

User says: “Cắt luật A”
System automatically discovers source → segments if needed → plans mapping → creates IU rows → birth fires → profiles/provenance are attached → edges are proposed/created → assembly/read/edit workflows work.

Therefore, after R1/R2 successfully place the first 86 TAC units into IU, GPT will prioritize:

1. DOT automated cutter — one command to cut a KB/law document into IU, with discovery, segmentation, vocab/birth/profile/gate validation, rollback, and report.
2. MCP wrapper / tool surface — GPT/Opus/Agent can call IU creation through a governed API/tool, not only through ad hoc CLI prompts.
3. Auto-edge / professional linkage — create/suggest typed edges from law unit → requirement → process → code → report, using existing universal_edges/NĐ-36-01 principles.

This is now a near-term mainline, not a vague long-term item.

Required next Agent task

Create and run a combined execution prompt:

PHASE5C2_RETRY_R1_AND_CONDITIONAL_R2_PATCHED_V3

Deliverables:

• R1 retry report.
• R1 rollback keys if transaction reaches key capture.
• R2 D28 mapping/execution report if R1 PASS and D28 gates PASS.
• R2 D32 mapping/execution report if R1 PASS and D32 gates PASS.
• Consolidated 86-unit status report.
