Verdict

Status: ACCEPT_R0_MAPPING_ARTIFACT__AUTHORIZE_R1_PROMPT_DRAFT_ONLY

The R0 mapping artifact is accepted as sufficient to draft the R1 execution prompt. This does not authorize R1 execution.

Gate assessment

R0 passed the required mapping gates:

• 23/23 G0 gates PASS.
• DIEU-35 live source has 36 rows.
• Render order is contiguous 0..35.
• 12/12 distinct section types have vocab keys.
• Existing IU collision count is 0.
• All 36 rows mapped and classified READY_FOR_R1.
• No live functions were executed.
• No PG writes were performed.

Soft-flag to carry into R1

R0 flagged one non-blocking source-content anomaly:

render_order=26
canonical_address=D38-DIEU35-S8-P3
section_type=governance_process
body_char_count=1
status=READY_FOR_R1 with soft-flag

Decision:

• This is not a migration blocker because R1's purpose is to mirror TAC live state exactly and preserve 0-drift.
• R1 must not auto-fix, infer, expand, or patch this body.
• R1 execution report must highlight this row again under source_soft_flags and confirm it was migrated exactly as source if R1 proceeds.
• If User later wants semantic repair, it must be handled as a separate TAC/IU content correction workflow after migration or before migration under a separate approval.

Authorization boundary

Authorized now:

Draft R1 execution prompt for DIEU-35 pilot migration.
R1 prompt may be prepared for review.

Still forbidden:

r1_execution_allowed=false_until_user_go_and_gpt_final_review
bulk_migration_allowed=false
ui_cutover_allowed=false
vector_work_allowed=false
schema_mutation_allowed=false
trigger_change_allowed=false
birth_system_change_allowed=false
pattern_delete_allowed=false

R1 prompt requirements

The R1 prompt must implement a bounded 36-row DIEU-35 pilot migration using the accepted R0 artifact as the plan of record.

It must include:

1. Preflight read-only checks identical to R0 gates.
2. Explicit User/GPT approval checkpoint before BEGIN.
3. Single bounded transaction for 36 rows only.
4. fn_iu_create canonical writer only; no direct INSERT into IU/UV.
5. Post-create profile patch under allowed gateway marker only.
6. Capture exact IU IDs, UV IDs, and birth entity_codes.
7. Dual-write rollback keys to KB and VPS log before COMMIT.
8. In-transaction validation V-1..V-7 before COMMIT.
9. Post-COMMIT validation V-8..V-10.
10. Exact-key rollback plan only; pattern deletion prohibited.
11. TAC source untouched verification.
12. UI cutover forbidden.
13. Vector work forbidden.
14. Existing 12 pilot/test IU rows must remain untouched.
15. Soft-flag row D38-DIEU35-S8-P3 must be reported, not fixed.

Next artifact to create

Create:

knowledge/dev/laws/dieu44-trien-khai/prompts/agent-phase5c2-r1-dieu35-pilot-migration-execution-prompt-DRAFT.md

Status should be DRAFT / NOT DISPATCHED until explicit User GO and GPT final review.
