# Investigator-Codebase Agent — Persistent Memory
> **Persistent diary cross-session.** Auto-injected first ~200 lines at spawn (L1 HOT). Update BEFORE every stop; keep entries to 1 line (gotcha #53 truncation — index hit 28KB @S148, hard-cap 24.4KB). Detail → `archive/2026-07.md` + `archive/_INDEX.md` (sha-keyed substring, Ctrl-F) + git `d2f52ba` + `archive/2026-0{5,6}.md` + `runs/*/sub-*.md`. Renamed S39: investigator → investigator-codebase (internal; external → investigator-api).
## 🎯 Role baseline
Read-only INTERNAL audit SOLUTION_ERP. Tools: Read/Grep/Glob/Bash + 5 RAG MCP. Output: concise <500w + file:line. Skills: contract-workflow + permission-matrix + ef-core-migration.
- MINE: sqlcmd schema scan, EF/grep, controller/authz audit, migration diff, count grounding
- NOT: external docs/CVE/lib investigator-api · write implementer · test test-specialist · architecture decision em main

## 📋 Patterns proven
### Schema scan sqlcmd
```
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Dev -Q "..." # runtime API (primary)
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Design -Q "..." # ef tooling
```
Prod: `ssh vietreport-vps` powershell-wrapper `sqlcmd -S '.\SQLEXPRESS' -d SolutionErp -E …` **SSH session DIES whenever SQL-client loads** (S134/S148 re-confirm); prod-DB effectively UNVERIFIABLE this path, flag + give query for implementer. **2 LocalDB distinct**: `_Dev`=runtime · `_Design`=`dotnet ef` default. Queries: `sys.columns/indexes/tables`, `__EFMigrationsHistory`, dup-detector `REPLACE(Code,' ','')`.
### Controller / wire-claim audit
- Grep `\[Route\("api/[a-z]+"\)\]` controllers · `\[Authorize(Policy="…"` per-action (gotcha #44 silent-403; class-level `[Authorize]` trần = no phase-guard, S147)
- Grep `// Mock` / `alert(` / `setEditing(null) // close UI` wire bugs
### Memory cross-reference
30 user-memory `C:\Users\pqhuy\.claude\projects\D--…\memory\MEMORY.md`. Key: designtime_runtime_db · workflow_fanout_reliability · canonical_spec_over_broadcast · root_cause_over_symptom · cardinality_change_grep_consumers.
## ⚠️ Anti-patterns
Skip MEMORY update · Vague "seems/probably" · Missing file:line · >500 words · ❌ Scope drift to architecture rec (em main decides) · ❌ Multi-line MEMORY entries (index truncates >24.4KB)
## 🧠 SOLUTION_ERP context (numbers canonical → docs/STATUS.md; re-ground don't trust)
- **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). Last-schema Mig 67 `AddPeApprovedBudgetSnapshot` (S133); ~67 mig.
- **Counts (docs/STATUS.md canonical):** ~88 SQL tables (count `.ToTable()` snapshot NOT DbSet) · ~253 endpoints · 68 FE pages · 54 menu keys (`MenuKeys.cs`) · ~354 test · ~71+ gotchas · 14 sub-agents (worker-tier-pin S124)
- **Tech:** .NET 10 Clean Arch (Api→Application←Domain + Infra) + CQRS MediatR + EF Core 10 + 2 React Vite TS (fe-admin :8082 + fe-user :8080) + SQL Server + Gitea CI + IIS
- **Prod:** api/admin/eoffice.solutions.com.vn · Gitea `git.baocaogiaoduc.vn/…/solution-erp` (Actions API `/actions/tasks` NOT `/runs`, cache stale ~2min #46)
- **Auth:** `admin@solutions.com.vn/Admin@123456` (full) / `nv.test@solutions.com.vn/TestUser@123456` (Drafter). Password ≥12.
## 🔄 Active workflow schemas (V1 + V2 coexist post-S17)
- **V1 Mig 21 flat** — `WorkflowDefinition` pin cũ, match Dept+PositionLevel.
- **V2 Mig 22-31** — `ApprovalWorkflow` pin PE/Contract, match `ApproverUserId` 1-1 OR-of-N cùng Cấp. Steps(Phòng)>Levels(Cấp). Proposal V2 Mig38, WorkflowApps Mig39. (Mig25 IsUserSelectable · 26 LevelOpinions UPSERT · 30 AllowApproverEditBudget · 31 SkipToFinal→ApproverLevel · 53 cờ-gấp+CeoThreshold · 54 giá-đề-xuất · 58 IsWinner multi + AllowApproverFinalize · 65 Quote.IsSelected per-hạng-mục · 66 ApprovedPrice Min-Max · 67 budget-freeze snapshot).
- **State PE 5:** Nháp / Đã gửi duyệt / Trả lại (TraLai=98) / Từ chối (TuChoi, REMOVED-path S60) / Đã duyệt
- **Mode Trả lại 4:** OneLevel / OneStep / Assignee / Drafter (Phase=TraLai). 3 đầu giữ ChoDuyet lùi pointer. Admin bypass `level.Allow*`.
- **Seeds gating:** `SeedDemoMasterDataAsync` gated `DemoSeed:Disabled` (OFF prod) · `SeedRealMasterDataAsync` UNGATED (62 dự án + 71 hạng mục Excel, per-code idempotent, exact-Code key #75/#76 resurrect risk).
## 🔄 Curate log
- **S155 (07-27):** hook @19.5KB → compact 20.7→~17.1KB: gộp S122-S141 thành 1 dòng, trim 3 entry S155 (detail nguyên vẹn ở `runs/2026-07-27-S155-pe-delete-approver/sub-*.md`) + S153.
- **S148 (07-23):** hard-cap rewrite 28.2→~14KB — collapsed multi-line S133-S148 → 1-liner, dropped stale pointer-list (S87-S114 → grouped 1-line, verbatim in archive/git).
- **Prev:** S125 (23.9→~15KB) · S71/S70/S40. Verbatim byte-exact in `archive/`.
