S167G — Scanner Hardening + Automation Health Report

Date: 2026-03-26 | Agent: Claude CLI (claude-go) PR: #635 (MERGED at 2026-03-26T06:51:03Z) | Branch: fix/s167g-scanner-hardening Tiền nhiệm: S167F (Codex 11/21 + Gemini ~13/21)

STEP 0: Schema Integrity Check — PASS

Check	Result
Columns normal (8 tables)	152 columns, all expected
No suspicious directus_fields	Sequential IDs, no post-chaos additions
Duplicate meta_catalog for dot_tools	Only 1 row (CAT-006) — CLEAN
Chaos residue in entity_deps	0 — CLEAN
Duplicate active meta_catalog (all)	6 with NULL registry_collection (expected)

Không có cột lạ. Gemini chaos test KHÔNG ALTER TABLE.

PHẦN A: 7 Scanner Blind Spot Checks — DONE

Implementation: Extended pg-vs-nuxt-check.js with pg_query target_type + sync_drift/vector_parity comparison modes. 7 rows added to measurement_registry. Constraint updated for new comparison modes.

Check	ID	Type	Result	Detail
A1: _dot_origin NULL	MSR-D31-A1	pg_query	FAIL (WARNING)	2079 NULLs across 18 managed collections
A2: Broken entity_deps	MSR-D31-A2	pg_query	PASS	0 broken source_code references
A3: Broken universal_edges	MSR-D31-A3	pg_query	FAIL (WARNING)	2040 broken references
A4: Circular dependencies	MSR-D31-A4	pg_query	PASS	0 cycles (recursive CTE)
A5: Sync drift	MSR-D31-A5	nuxt_api/sync_drift	PASS	AD 585 >= Directus 371
A6: Vector parity	MSR-D31-A6	nuxt_api/vector_parity	PASS	ratio 1.47 < 2.0 threshold
A7: Duplicate meta_catalog	MSR-D31-A7	pg_query	PASS	0 duplicates

Ghi chú:

• A1 FAIL là finding thật: 2079 records thiếu _dot_origin. Cần backfill.
• A3 FAIL là finding thật: 2040 universal_edges có source/target_code trỏ đến entity không tồn tại.
• A2 fix: workflows dùng process_code thay vì code. Đã sửa.
• A4 fix: CTE cần explicit ::text cast cho varchar(50). Đã sửa.

PHẦN B: Automation Health — DONE

Fix	Before	After	Evidence
B1: Scanner cron	Daily 20:00 UTC	Every 6h (0 */6 * * *)	crontab -l
B2: Watchdog token	gcloud failed -> "No token — skipping"	Sources from /opt/incomex/docker/.env	WATCHDOG OK: Runner alive (last seen 9s ago)
B3: Runner DATABASE_URL	Wrong path /opt/incomex/deploys/docker/.env	Correct path /opt/incomex/docker/.env	PG connected successfully
B4: Watchdog curl	Missing -g flag -> URL bracket parse error	Added -g (globoff)	Watchdog reads issue correctly

PHẦN C: Duplicate meta_catalog — NO ACTION NEEDED

SELECT registry_collection, COUNT(*) FROM meta_catalog 
WHERE status='active' AND registry_collection IS NOT NULL 
GROUP BY registry_collection HAVING COUNT(*) > 1;
-- 0 rows

dot_tools chỉ có 1 row (CAT-006). Gemini chaos đã được Codex cleanup trong S167F.

PHẦN D: Chaos Residue — CLEAN

SELECT COUNT(*) FROM entity_dependencies 
WHERE source_code LIKE '%CHAOS%' OR target_code LIKE '%CHAOS%' 
   OR source_code LIKE '%FAKE%' OR target_code LIKE '%FAKE%'
   OR source_code LIKE '%GEM%' OR target_code LIKE '%GEM%';
-- 0

POST-DEPLOY VERIFICATION (run_id: s167g-post-deploy)

PASS: 6 | FAIL: 4 | ERROR: 0 | WATCHDOG: alive
Pass Rate: 60.0% (6/10)
Issues Created: 0 | Reopened: 4

FAILs gồm:

• MSR-AUTO-GEM_CHAOS_P1: pre-existing broken measurement (source_query returns null) — không thuộc S167G
• MSR-D31-101: L1 vs PG off-by-one (19090 vs 19091) — eventual consistency, không phải bug
• MSR-D31-A1: 2079 _dot_origin NULL — real finding, WARNING
• MSR-D31-A3: 2040 broken edges — real finding, WARNING
