- Lesson env: CCD harness cache agent frontmatter — restart CLI mới ăn (2 data-point 06-10/06-11).

+> **Architecture:** 11 sub-agents **two-tier model (Harness-4 2026-06-10)** + em main **Fable 5 (1M) Max** coordinator — **9 product/quality** (7 core + frontend-designer pink S47 + database-agent read-advisory S52) + **2 monitor INFORM-only** (`tooling-auditor` H1 + `harvest-curator` H2, 2026-06-07 Harness 1). Tier: **4 promote `model: inherit` = Fable 5 1M** (reviewer H4.3a · investigator-codebase H4.3b · database-agent H4.3b · harvest-curator H4.3c) · **7 demote pin `claude-opus-4-8`** (2 implementer · test-specialist · cicd-monitor · investigator-api · frontend-designer · tooling-auditor) · effort **Max cả 2 tier** (env machine-wide).
 > **Upgrade S52 (2026-06-08 — AI_INFRA broadcast `2026-06-08-Agent-database-codebase-agents`):** **+database-agent (read-advisory DB specialist, floor DB1–DB11)** — schema/query/migration-design-review/perf/concurrency (DB11 RowVersion vá lost-update S43). Tailor READ-tier (implementer-backend vẫn author) · color OMIT (8 standard hết) · `store_memory` strip. `codebase-agent` = **SKIP n-a** (investigator-codebase đã cover grep/audit + `csharp-lsp` Windows no-op). ✅ **verified-runtime** — spawned OK S53 (first real spawn, caught Mig 46 committed-but-unapplied-local drift) + S56 2× (pre-golive-verify schema-stream + golive-harden design+review). DB11 lost-update fix landed S56 (atomic ExecuteUpdate + Serializable tx, gotcha #58).
 > Pattern: Anthropic Building Effective Agents orchestrator-workers + Cognition "writes single-threaded" hybrid + post-deploy automated watchdog.
 > **Upgrade S39 (2026-05-29):** 4→7 agent (split investigator + implementer, +test-specialist) + budget +50% + 5 RAG MCP per agent. Reference BVAAU 7-agent config (adapted, NOT copied — SOLUTION_ERP 2-FE-app fit + 6 skill proven battle-test 38 session). Prior: S20t12 initial 3 + S21t1 +cicd-monitor.
 > **Upgrade S47 (2026-06-02):** **+frontend-designer (8th sub, pink)** — FD1–FD10 visual-verification design floor (forked AI_INFRA canonical, broadcast `Agent-frontend-designer-floor`). + **`store_memory` STRIPPED khỏi MỌI sub → lead = sole RAG-writer** (broadcast `Memory-store-memory-strip-global`); sub ghi finding → MEMORY.md (file). adap-reports: `docs/governance/adap-reports/`.
 > **Upgrade 2026-06-07 (Harness 1·2·3 adopt — AI_INFRA broadcast):** **+2 monitor sub INFORM-only** `tooling-auditor` (H1 tooling/docs-freshness 4-mặt) + `harvest-curator` (H2 harvest-integrity 5-trục) → roster 8→10, **TÁCH BIỆT** per anh-mandate (H1≠H2 "hay quên+nhầm"). + **wave-folder memory-isolation** (Harness 2 — `hmw.js` wave-mode + `.claude/workflows/wave-*/` gitignored, B1–B6). + **email channel** `broadcasts/` (Harness 3 — cross-project comms, self-id=`se`). KHÔNG copy-paste AI_INFRA — tailor SE roster/stack.
+> **Upgrade 2026-06-10 (Harness-4 two-tier model — AI_INFRA broadcast `harness-4-model-tier-promotion` + `model-fable-5-max`):** lead = **Fable 5 (1M) Max** (user-level machine-wide, SE không project-pin) · sub two-tier theo tiêu chí H4.3 (a gate≥writer · b verdict-nuôi-quyết-định · c chống-rubber-stamp · d 1M-thật): **promote 4 giữ `inherit`** (reviewer·investigator-codebase·database-agent·harvest-curator) + **demote 7 pin `claude-opus-4-8`** (full-id no-suffix — gotcha #37 cấm `[1m]`; runtime resolve `[1m]` 1M trên máy chung per AI_INFRA s20). `hmw.js` tier-map H4.5 (role-less → `'opus'` · per-task `tier:'fable'|'opus'` override).
