3. R1 readiness classification

Class	Count
`READY_FOR_R1`	36
`BLOCKED_COLLISION`	0
`BLOCKED_MISSING_OWNER`	0
`BLOCKED_MISSING_BODY`	0
`BLOCKED_MISSING_VOCAB`	0
`BLOCKED_UNKNOWN`	0

rows_ready_for_r1=36, rows_blocked=0.

3.1 Soft-flag for human review (not a blocker)

Row at render_order=26 (D38-DIEU35-S8-P3) has src_body_char_count=1 (body present but only one character). Body is technically non-NULL so the row passes the body-missing check; flagged here for human review during the R1 decision because a 1-char body may be a placeholder.

4. 36-row mapping (compact view)

Full per-row planned_fn_iu_create_call_string, planned_identity_profile_patch, and planned_content_profile_patch are in the companion JSON artifact at knowledge/dev/laws/dieu44-trien-khai/artifacts/p3d-phase5c2-r0-dieu35-mapping-artifact.json (revision 1).

All 36 rows: unit_kind='law_unit', publication_type='law', publication_authority_ref='incomex_council', p_parent_ref=NULL (D3a hybrid).

5. Planned `fn_iu_create` call template (string only — NOT executed)

Identical shape for every row (per-row values from §4 and the JSON artifact):

-- STRING ARTIFACT ONLY. R0 DOES NOT EXECUTE. R1 will.
SELECT public.fn_iu_create(
  p_canonical_address := '<src_canonical_address>',
  p_title             := '<src_title>',
  p_body              := <body omitted in R0; source=tac_unit_version.id=<src_unit_version_id>>,
  p_actor             := 'agent:p3d-phase5c2-r1',
  p_unit_kind         := 'law_unit',
  p_section_type      := '<src_section_type>',
  p_owner_ref         := '<src_owner>',
  p_publication_type  := 'law',
  p_parent_ref        := NULL
);

Example for render_order=0 (root):

SELECT public.fn_iu_create(
  p_canonical_address := 'D38-DIEU35-ROOT',
  p_title             := 'ĐIỀU 35: LUẬT QUẢN TRỊ DOT — v5.2 FINAL',
  p_body              := <body omitted in R0; source=tac_unit_version.id=9ed7b93b-48b7-4abb-8c1c-a3e82ff47c71>,
  p_actor             := 'agent:p3d-phase5c2-r1',
  p_unit_kind         := 'law_unit',
  p_section_type      := 'article',
  p_owner_ref         := 'S178-FIX23',
  p_publication_type  := 'law',
  p_parent_ref        := NULL
);

6. Planned `identity_profile` JSON patch (10 logical keys)

R0 designs the patch shape per row; R1 will apply it post-fn_iu_create under SET LOCAL "app.canonical_writer" = 'fn_iu_apply_edit_draft'. Example (row 35, D38-DIEU35-S15):

{
  "tac_provenance": {
    "src_publication_id": "27e48995-d6a1-4a44-8559-cab6a07fdbe0",
    "src_publication_doc_code": "DIEU-35",
    "src_publication_version": "v5.2",
    "src_publication_type": "law",
    "src_logical_unit_id": "5d55777c-1922-4c19-9c42-4cd218ac641f",
    "src_unit_version_id": "50c06167-a40c-43f0-8932-a3a8861460f3",
    "src_version_number": 1,
    "src_render_order": 35,
    "src_sort_order": 35,
    "src_section_code": null,
    "src_review_state": "unreviewed",
    "src_lu_lifecycle": "draft_only",
    "src_uv_lifecycle": "draft"
  },
  "tac_hierarchy": {
    "src_parent_id": "7394552d-2cca-449c-b852-2d24c791b430",
    "src_parent_canonical_address": "D38-DIEU35-ROOT",
    "depth_from_root": 1
  },
  "publication_authority_ref": "incomex_council",
  "publication_authority_vocab_key": "vocab.publication_authority.incomex_council",
  "rendering": {
    "render_order": 35,
    "section_type": "checklist"
  }
}

Idempotent merge semantics for R1: UPDATE information_unit SET identity_profile = COALESCE(identity_profile,'{}'::jsonb) || $patch WHERE canonical_address = $src_canonical_address.

7. Planned `content_profile` JSON patch (per UV)

Example (row 0, root):

{
  "source_kind": "tac_unit_version",
  "src_unit_version_id": "9ed7b93b-48b7-4abb-8c1c-a3e82ff47c71",
  "src_version_number": 1,
  "src_content_hash": "f3f34402deb6853b6ab60d5c43a4766a36334d6cc14b456603f5a1db06422e02",
  "src_provenance": "PROV-AI",
  "migrated_by": "agent:p3d-phase5c2-r1",
  "migrated_at": "<utc-set-at-R1-execution>"
}

Applied to unit_version.content_profile for the v1 UV that fn_iu_create produced. Plain-text unit_version.provenance set to tac:DIEU-35:<src_unit_version_id>.

8. Exact-key rollback skeleton (placeholders only — NOT executed in R0)

-- ROLLBACK SKELETON. R0 EMITS PLACEHOLDERS. DO NOT EXECUTE.
-- Capture during R1: $captured_iu_ids (uuid[]), $captured_uv_ids (uuid[]),
--                    $captured_iu_entity_codes (text[] of 'information_unit::<uuid>')
BEGIN;
SET LOCAL "app.canonical_writer" = 'fn_iu_apply_edit_draft';
DELETE FROM birth_registry
  WHERE collection_name = 'information_unit'
    AND entity_code = ANY( $captured_iu_entity_codes );
DELETE FROM unit_version
  WHERE id = ANY( $captured_uv_ids );
DELETE FROM information_unit
  WHERE id = ANY( $captured_iu_ids );
COMMIT;

PATTERN-MATCHING DELETION REMAINS PROHIBITED. R1 must dual-write the captured-UUID bundle to both KB AND VPS log BEFORE COMMIT (per design §8).

9. Observations / non-blockers flagged for review

#	Item	Class
O-1	Row `render_order=26` (`D38-DIEU35-S8-P3`) has body_char_count=1	SOFT-FLAG (not a blocker; technically non-NULL body)
O-2	All 36 rows share single owner `S178-FIX23`	NORMAL (consistent ownership for this publication)
O-3	All `tac_logical_unit.section_code` values are NULL	NORMAL (section_code is nullable on source; not required by `fn_iu_create`)
O-4	TAC `lifecycle_status='proposed'` (publication) and `draft_only`/`draft` (LU/UV)	NORMAL (5C2 is parallel pilot; not a status transition)
O-5	Vector sync columns (`vector_sync_status`, `vector_synced_at`, `vector_chunk_count`) on source `tac_unit_version` are NOT carried into the planned `content_profile` patch	INTENTIONAL — vector work is OUT-OF-SCOPE for 5C2
O-6	`tac_logical_unit.parent_id` is preserved in `identity_profile.tac_hierarchy.src_parent_id` + `src_parent_canonical_address`	as designed (D3a hybrid; FK enrichment is a later pack)
O-7	`depth_from_root` max = 2 (3-level tree: ROOT → S0..S15 → S4-P1..P4, S6-P1..P7, S8-P1..P5)	normal for D35

None of O-1..O-7 block R0 or R1.
