Investigator-Codebase Agent — Persistent Memory

Persistent diary cross-session. Auto-injected first 200 lines / 25KB at spawn. Update BEFORE every stop. Curate when > 25KB. Keep entry ≤ 1.5K chars (gotcha #53). Full verbatim history pre-S40 → git d2f52ba + archive/2026-05-q1..q4.md. 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

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>

⚠️ Anti-patterns

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