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

⚠️ 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)
