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

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.

⚠️ Anti-patterns

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