title: P10B-2C-PF — D28 SQL Inspection Preflight Report date: 2026-04-29 phase: P10B-2C-PF spec_version: v0.2 mode: READ-ONLY (no SQL executed) verdict: PASS

P10B-2C-PF Preflight Inspection — Đ28 v2.0 Candidate Insert Package

Date: 2026-04-29 Spec: P10B-2C-PF v0.2 (P1 JSON SHA in T1, P2 body-strip before destructive scan, P3 sanitized INSERT, P4 3-point delimiter safety) Mode: Read-only file inspection. NO SQL executed against any database. NO EXPLAIN. NO BEGIN/ROLLBACK test. NO connection.

§1 — File existence + SHA verification (T1)

5/5 files present at /tmp/p10b-2b/. SHAs match P10B-2B report:

File SHA256 Match
insert-candidate.sql 767450fd…0627489b ✅
render.sql 839ac900…6b9e0f2f ✅
rollback.sql 9a2def1e…4f38b8af ✅
verify-counts.sql 3bdfd8f2…be217121 ✅
candidate-units-r2.json e47775e3…b165de8ad ✅

§1 verdict: PASS

§2 — Transaction structure (T2)

Line   5:  BEGIN;
Line 251:  -- ROLLBACK;  -- default safe stop for dry-run
Line 252:  -- COMMIT;    -- only when authorized by P10B-2C

Raw counts: BEGIN=2, COMMIT=1, ROLLBACK=1, DO $=0. The second BEGIN (line 115) is the keyword inside a PL/pgSQL function example that lives inside a $body$…$body$ literal (S3-P3 body, the fn_template_lifecycle_guard example) — not an outer SQL statement.

Outer-SQL state:

  1. Starts with BEGIN; ✅
  2. Ends with both -- ROLLBACK; and -- COMMIT; commented ✅
  3. No DO block ✅
  4. No bare (uncommented) COMMIT or ROLLBACK ✅
  5. Uncommenting -- COMMIT; → safe and unambiguous ✅

§2 verdict: PASS — COMMIT uncomment is SAFE.

§3 — INSERT count (sanitized) (T3)

Sanitization method: stripped block comments + line comments + dollar-quoted body literals before counting. Initial naive re.sub(r'\$body\$.*?\$body\$', …) yielded incorrect pairing (1 unmatched token leaked, mis-paired by 1). Replaced with a position-based check: an INSERT INTO occurrence is "outer SQL" iff the count of $body$ tokens before its position is even. This is robust against any body content.

Target Expected Actual Status
tac_publication 1 1 ✅
tac_logical_unit 27 27 ✅
tac_unit_version 27 27 ✅
tac_publication_member 27 27 ✅
Total 82 82 ✅

No unexpected targets. No real-table writes outside the four expected tables.

§3 verdict: PASS — 1 + 27 + 27 + 27 = 82.

§4 — Destructive command scan (sanitized) (T4)

Same position-based body detection used for T3. Scanned for ALTER, DROP, TRUNCATE, UPDATE, DELETE, and non-temp CREATE on the outer SQL only.

  • Real destructive (outside $body$): 0
  • Non-temp CREATE (outside $body$): 0
  • Temp / ON COMMIT DROP constructs: 0 (none used)

Note: an earlier non-greedy strip falsely flagged two UPDATE status='…' matches; both live inside the S6 body markdown describing template lifecycle steps. The position-based sanitizer correctly excludes them.

§4 verdict: PASS — no destructive commands on real tables (body literals excluded).

§5 — Dollar-quoting 3-point safety (T5)

Point Check Result
P1 No JSON body contains literal $body$ ✅ 27/27 units clean
P2 Generated SQL has even count of $body$ (paired) ✅ 930 occurrences = 465 pairs
P3 S3-P3 PL/pgSQL $$ does not conflict with $body$ wrapper ✅ S3-P3 body uses $$ … $$, inert inside $body$ outer wrapper (PostgreSQL nests dollar-quotes by tag)

Only two distinct dollar-quote tags appear in the file: $$ (PL/pgSQL example body, inside $body$) and $body$ (outer SQL string delimiter). No third tag, no collision.

§5 verdict: PASS — delimiter scheme is safe at all three points.

§6 — Sample mapping

§6.1 ROOT (D38-DIEU28-ROOT) — container, empty body

  • LU INSERT: line 16 — INSERT INTO tac_logical_unit (canonical_address, doc_code, parent_id, sort_order, section_type, owner, lifecycle_status) VALUES ($body$D38-DIEU28-ROOT$body$, $body$DIEU-28$body$, NULL, 0, $body$heading$body$, $body$editor$body$, $body$draft_only$body$);
  • UV INSERT: line 45 — body field is NULL (correct: ROOT has empty body), title = ĐIỀU 28: LUẬT KỸ THUẬT HIỂN THỊ — v2.0 BAN HÀNH.
  • PM INSERT: line 216 — render_order = 1.
  • parent_id resolution: explicit NULL (root anchor).
  • Body delimiter: $body$ for string literals; body column = NULL.

§6.2 S3-P3 (D38-DIEU28-S3-P3) — highest escaping risk

  • LU INSERT: line 30 — parent_id resolved by subquery against D38-DIEU28-S3 + doc_code=DIEU-28 (correct hierarchical resolution).
  • UV INSERT: lines 113–139 (multi-line body). Title = ★ PG TRIGGER enforce lifecycle (Tuyên ngôn ②). Body contains a fenced ```sql code block with a complete CREATE FUNCTION fn_template_lifecycle_guard() RETURNS TRIGGER AS $$ … $$ LANGUAGE plpgsql; definition followed by CREATE TRIGGER trg_template_lifecycle ….
  • PM INSERT: line 230 — render_order = 15.
  • Body escaping delimiter: outer $body$ … $body$ wraps the entire markdown body; the inner PL/pgSQL $$ … $$ is a different tag and is therefore inert w.r.t. the outer quote (PostgreSQL dollar-quote tags are tag-scoped).
  • Body integrity: code fences preserved (```sql / ```), $$ markers preserved, BEGIN/END;/RAISE EXCEPTION text preserved, narrative italic line → Agent KHÔNG THỂ active … preserved at line 139.
  • LU INSERT: line 42 — parent = ROOT, sort_order = 12, section_type = paragraph.
  • UV INSERT: line 213. Title = Footer. Body = single italic line wrapped in *…*: *Điều 28 v2.0 BAN HÀNH | 13/13 NT ✅ | 6/6 Q ✅ | Ref table status | PG trigger lifecycle+checklist guard | DOT paired rõ | instance_collection FK | Dùng chung dot_config*. Italic markers preserved.
  • PM INSERT: line 242 — render_order = 27 (last).
  • Body escaping delimiter: $body$.

§6 verdict: PASS — sample mapping verified across container, technical-spec, and footer.

§7 — render.sql + verify-counts.sql (T7)

render.sql

  • Self-scoped: WHERE lu.doc_code=$body$DIEU-28$body$ (recursive CTE) and WHERE p.doc_code=$body$DIEU-28$body$ AND p.version=$body$v2.0$body$ (final SELECT). ✅
  • No :pub_id parameter; uses doc_code+version literals. ✅
  • Output columns: depth, canonical_address, section_type, title, body. ✅
  • Algorithm: WITH RECURSIVE tree doing preorder DFS via materialized path array (sort_order chain), joined to UV (version_number=1) and PM/publication.

verify-counts.sql

  • Self-scoped via doc_code=DIEU-28 and version=v2.0. ✅
  • No :pub_id parameter. ✅
  • Output: 5 rows — pub, lu, uv, pm, total (expected 1 + 27 + 27 + 27 = 82).

§7 verdict: PASS.

§8 — Final verdict

ALL 7 TASKS PASS.

Criterion Status
1. 4 SQL + 1 JSON exist + SHA match P10B-2B ✅
2. Transaction structure clear; COMMIT uncomment safe ✅
3. INSERT count (sanitized) = 1+27+27+27 = 82 ✅
4. No destructive SQL on real tables (sanitized) ✅
5. Dollar-quoting 3-point safety verified ✅
6. Sample mapping verified (ROOT + S3-P3 + S11) ✅
7. render.sql + verify-counts.sql self-scoped ✅

Verdict: PASS — Đ28 v2.0 candidate insert package is structurally sound and safe to advance to P10B-2C upon GPT authorization.

STOPPED. No SQL executed. Awaiting Opus review + GPT authorize for P10B-2C.

§9 — Notes / followups

  • Spec note: T3's re.sub(r'\$body\$.*?\$body\$', …, flags=re.DOTALL) non-greedy strip in v0.2 produced mis-aligned pairing on this file (1 trailing $body$ left after sub; PM lines collapsed). A position-based sanitizer (count $body$ tokens before each match → outer iff even) was used and gave correct counts. Recommend updating future preflight specs to use the position-based form.
