Bước 0.5: Directus Insights

Kết quả: KHÔNG ĐỦ — Directus Insights hỗ trợ aggregation charts 1D (count/sum/avg). KHÔNG có cross-tab/pivot matrix config-driven. → Cần PG function.

Bước 0: Xác minh hiện trạng

Item	Kết quả
pivot_results	TỒN TẠI. 92 rows → nay có thêm 19 matrix rows. Thêm field needs_refresh (boolean)
pivot_definitions	TỒN TẠI. 18 cols → thêm matrix_spec (json). Có 2 matrix configs mới
birth_registry	25,301 entities. 4 composition_level, 3 governance_role
collection_registry	birth_registry = COL-140 ✅
Cron	*/10 refresh + 4AM health đã có. Thêm */10 refresh_matrix_results() + 4:05AM dot-matrix-health
identity_class	KHÔNG TỒN TẠI → dùng governance_role. TD ghi nhận

V1: pivot_matrix() → JSONB

[
  {"row": "atom",     "total": 24574, "columns": {"excluded": 5563, "governed": 1806, "observed": 17205}},
  {"row": "compound", "total": 35,    "columns": {"governed": 32, "observed": 3}},
  {"row": "meta",     "total": 35,    "columns": {"governed": 35}},
  {"row": "molecule", "total": 657,   "columns": {"excluded": 113, "governed": 276, "observed": 268}}
]

V2: EXPLAIN ANALYZE → 34ms ✅

Scale assessment: OK (34ms trên 25,301 rows). Dưới 1s. TD: cần materialized view khi data >1M.

V3: Matrix Configs ✅

Code	Name	Spec
MTX-L1-OVERVIEW	Ma trận L1: Lớp cấu tạo × Lớp quản lý	row=composition_level, col=governance_role
MTX-L2-ATOM	Ma trận L2 Atom: Loài	row=species_code, filter=atom

V4: Independent Cross-check ✅

• Matrix SUM (MTX-L1-OVERVIEW): 25,301
• Raw COUNT(*) FROM birth_registry: 25,301
• KHỚP ✅

V5: dot-matrix-health → ALL PASS ✅

MTX-L1-OVERVIEW: Check A ✅ Check B ✅ (25301=25301) Check C ✅
MTX-L2-ATOM:     Check A ✅ Check B ✅ (24574=24574) Check C ✅
Summary: 2 PASS, 0 FAIL

V6: Trigger → ✅

• PG trigger trg_matrix_config_changed on pivot_definitions → sets needs_refresh=true ✅
• PG trigger trg_birth_change_flag_matrix on birth_registry (STATEMENT level) → flags all active matrix ✅
• refresh_matrix_results() resets needs_refresh=false after refresh ✅
• Cron */10 min picks up and refreshes ✅

V7: DOT Lifecycle → ✅

• DOT-matrix-declare: MTX-TEST created → 4 rows ✅
• DOT-matrix-retire: MTX-TEST → is_active=false, superseded_by='deprecated' ✅

V8: DOT Registration ✅

4 DOTs registered in dot_tools:

Code	Name	Tier	Trigger
DOT-312	dot-matrix-declare	A	manual
DOT-313	dot-matrix-update	A	manual
DOT-314	dot-matrix-retire	A	manual
DOT-315	dot-matrix-health	B	cron

Birth records: birth trigger trên dot_tools tự tạo.

V9: Directus Permissions ✅

matrix_spec field readable via API: present trên cả MTX-L1-OVERVIEW và MTX-L2-ATOM.

V10: 5 Tầng Sync

Tầng	Kết quả
1 (PG)	✅ matrix_spec có data
2 (Directus)	✅ API trả matrix_spec
3 (Nuxt)	S150-P2 (chưa làm)
4 (Agent Data)	✅ Agent Data biết MTX-L1-OVERVIEW
5 (Qdrant)	Theo tầng 4

PG Objects Created

Type	Name	Description
FUNCTION	pivot_matrix(source, row, col, agg, filter)	Dynamic 2D matrix, JSONB output
FUNCTION	refresh_matrix_results()	Refresh all active matrix → pivot_results
FUNCTION	fn_matrix_config_changed()	Trigger fn: config change → needs_refresh
FUNCTION	fn_birth_change_flag_matrix()	Trigger fn: data change → flag all matrix
TRIGGER	trg_matrix_config_changed	ON pivot_definitions AFTER INSERT/UPDATE
TRIGGER	trg_birth_change_flag_matrix	ON birth_registry AFTER INSERT/UPDATE/DELETE (STATEMENT)
FIELD	pivot_definitions.matrix_spec	JSON — matrix config
FIELD	pivot_results.needs_refresh	BOOLEAN — refresh flag

Files Changed

File	Action
dot/bin/dot-matrix-declare	NEW — DOT-312
dot/bin/dot-matrix-update	NEW — DOT-313
dot/bin/dot-matrix-retire	NEW — DOT-314
dot/bin/dot-matrix-health	NEW — DOT-315
dot/bin/dot-cron-matrix-setup	NEW — cron setup script

TD (Technical Debt)

1. Scale >1M: pivot_matrix() = 34ms/25K rows. Cần materialized view hoặc partition khi >1M.
2. td-matrix-dimensions: Trục #3 ghi sai field — identity_class không tồn tại trên birth_registry, cần update → governance_role.
3. Nuxt TPL-002 DirectusMatrix: S150-P2 — render component chưa có.

PRODUCTION VERIFICATION (2026-04-01 02:43 UTC)

PR #659: MERGED. Deploy: AUTO SUCCESS. V1: pivot_matrix() 4x3 JSONB OK. V2: 2 configs. V3: SUM=RAW=25303 MATCH. V4: 4 DOTs. V5: 2 triggers active. V6: 2 cron entries. V7: API matrix_spec present. V8: needs_refresh cycle OK. Post-merge fix: pg_trigger_depth() anti-loop in fn_birth_change_flag_matrix.
