# Investigator-Codebase Agent — Persistent Memory

> **Persistent diary cross-session.** Auto-injected first ~200 lines at spawn (L1 HOT).
> Update BEFORE every stop. Tiered Memory v1: L1 HOT soft-cap ~30KB · L2 `archive/` on-demand · L3 RAG `search_memory` just-in-time. Keep entry ≤ 1.5K chars (gotcha #53).
> Full verbatim history pre-S40 → git `d2f52ba` + `archive/2026-05-q1..q4.md` + `archive/2026-06.md`. 🗺️ **Lookup map: `archive/_INDEX.md`** — 1 dòng/bản-ghi + con-trỏ substring (sha-keyed, Ctrl-F fallback); đọc verbatim + `2026-0{5,6}.gist.md` theo nhu cầu. **S80 curate: moved 15 recon entries S65→S76 + 2× 06-20 → archive.**
> **Renamed S39:** investigator → investigator-codebase (internal half; external → investigator-api).

## 🎯 Role baseline

Read-only INTERNAL audit SOLUTION_ERP codebase. Tools: Read, Grep, Glob, Bash + 5 RAG MCP. Output: concise findings <500 words + file:line refs. Skills: `contract-workflow` + `permission-matrix` + `ef-core-migration`.

## 🚫 Split boundary (S39)
- ✅ MINE: internal SQL/EF/grep/reference mirror, sqlcmd schema scan, controller audit, migration diff, count grounding
- ❌ NOT: external docs/CVE/lib → `investigator-api` · write → implementer · test → test-specialist · architecture decision → em main

---

## 📋 Patterns proven (apply confidently)

### Schema scan via sqlcmd
```bash
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Dev -Q "..."     # runtime API (primary)
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Design -Q "..."  # ef tooling
ssh vietreport-vps "sqlcmd -S .\SQLEXPRESS -d SolutionErp -U vrapp -P '...' -Q '...'"  # prod
```
Queries: `sys.columns`, `sys.triggers`, `__EFMigrationsHistory`, `COUNT(*)`, `sys.indexes`.
**Gotcha 2 LocalDB distinct** (`feedback_designtime_runtime_db`): `_Dev`=runtime (appsettings.Development), `_Design`=`dotnet ef` default. Prod password fallback `C:\inetpub\solution-erp\api\appsettings.Production.json` khi `$env:PROD_DB_PASSWORD` empty.

### Controller / wire-claim audit
- Grep `\[Route\("api/[a-z]+"\)\]` enumerate controllers · `\[Authorize(Policy = "..."` per-action policy (gotcha #44 silent 403 class-level quá strict)
- Grep `// Mock` / `alert(` / `setEditing(null) // close UI` — wire claim bugs · `IActionResult` vs `ActionResult<T>`

### Smoke verify catalog
Bearer từ `POST api.solutions.com.vn/api/auth/login` → status matrix expected vs actual + file:line evidence.

### Memory cross-reference
30 user-memory tại `C:\Users\pqhuy\.claude\projects\D--...\memory\MEMORY.md` (index). Key: per_chunk_commit · uat_skip_verify · designtime_runtime_db · per_nv_permission_scope · ef_migration_backfill_reorder · workflow_fanout_reliability · canonical_spec_over_broadcast (S79).

### External research → DEFER `investigator-api` (split S39)

## ⚠️ Anti-patterns
❌ Skip MEMORY update · ❌ Vague "seems like/probably" · ❌ Missing file:line · ❌ >500 words · ❌ Scope drift to architecture recommendation (em main decides)

## 🧠 SOLUTION_ERP context essentials (S80 verified — re-ground từ docs/STATUS.md canonical)

- **DB:** Dev `SolutionErp_Dev` · Design `SolutionErp_Design` (distinct) · Prod `.\SQLEXPRESS`/`SolutionErp`/`vrapp` via SSH `vietreport-vps`
- **Migration path:** `src/Backend/SolutionErp.Infrastructure/Persistence/Migrations/*.cs` (⚠️ NOT root `/Migrations/`). **57 mig**, last `AddPeSuggestedPriceNotes`.
- **Counts S80 (canonical docs/STATUS.md):** 57 mig · **88 SQL tables** (count `.ToTable()` ModelSnapshot NOT DbSet) · ~253 endpoints · 68 FE pages · **54 menu keys** (BE `MenuKeys` const) · **354 test** (45 Domain + 309 Infra) · **71 gotchas** (format `### N.`) · 30 user-memory · 6 skills · **11 sub-agents** (all-inherit H8)
- **Tech:** .NET 10 Clean Arch (Api→Application←Domain + Infra) + CQRS MediatR + EF Core 10 + 2 React 19 Vite 8 TS 6 (fe-admin :8082 + fe-user :8080) + SQL Server + Gitea CI + IIS
- **Prod:** api/admin/eoffice.solutions.com.vn · Gitea `git.baocaogiaoduc.vn/vietreport-admin/solution-erp` (Actions API `/api/v1/repos/.../actions/tasks` NOT `/runs` 404, cache stale ~2min gotcha #46 — cross-check VPS mtime). Bundle live admin `CsJetgZH`/user `BVS0ApIm` (Run #330).
- **Auth:** `admin@solutions.com.vn/Admin@123456` (full) / `nv.test@solutions.com.vn/TestUser@123456` (Drafter). Response `accessToken`+`refreshToken`+`user`. Password ≥12 chars.

## 🔄 Active workflow schemas (V1 + V2 coexist post-S17)

- **V1 Mig 21 flat** — `WorkflowDefinition` pin PE/Contract cũ. Match Dept+PositionLevel.
- **V2 Mig 22-31** — `ApprovalWorkflow` pin PE/Contract mới, match `ApproverUserId` 1-1 OR-of-N cùng Cấp. Steps (Phòng) > Levels (Cấp). PE + Contract đã wire V2 (Mig 32+33 S29). Proposal V2 (Mig 38). WorkflowApps skeleton (Mig 39).
  - Mig 25 IsUserSelectable · Mig 26 PE LevelOpinions UPSERT · Mig 29 Allow* per-NV · Mig 30 F4 AllowApproverEditBudget · Mig 31 SkipToFinal→ApproverLevel · Mig 53 cờ-gấp+CeoApprovalThreshold · Mig 54 giá-đề-xuất PRO/CCM+giá-chốt · Mig 56 ProInitial/ProAdjust · Mig 57 ghi-chú-giá.
- **State machine PE 5 trạng thái:** Nháp / Đã gửi duyệt / **Trả lại (TraLai=98)** / Từ chối (REMOVED-S60 hard-guard) / Đã duyệt
- **Mode Trả lại 4 option per-Level:** OneLevel (lùi 1 Cấp) / OneStep (lùi Bước trước) / Assignee (pick NV đã ký) / Drafter (Phase=TraLai). 3 mode đầu giữ ChoDuyet lùi pointer. Admin bypass `level.Allow*`.
