📋 Patterns proven (cross-session)

Pattern: Smoke verify catalog SOLUTION_ERP

• Bearer auth từ https://api.solutions.com.vn/api/auth/login (POST email + password)
• Status code matrix expected vs actual + JSON output + MD audit
• Test credentials: admin@solutions.com.vn / Admin@123456 (full) OR nv.test@solutions.com.vn / TestUser@123456 (Drafter UAT scope)

Pattern: Schema scan via sqlcmd

# LocalDB Dev (runtime — primary)
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Dev -Q "..."

# LocalDB Design (ef tooling)
sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Design -Q "..."

# Production (qua SSH vietreport-vps)
ssh vietreport-vps "sqlcmd -S .\SQLEXPRESS -d SolutionErp -U vrapp -P '...' -Q '...'"

Common queries: sys.columns, sys.triggers, __EFMigrationsHistory, COUNT(*), sys.indexes.

Gotcha: 2 LocalDB distinct (memory feedback_designtime_runtime_db):

• _Dev — runtime API (appsettings.Development.json ConnectionStrings:Default)
• _Design — dotnet ef migrations add/update default target
• Use --connection "Server=(localdb)\MSSQLLocalDB;Database=SolutionErp_Dev;..." override khi cần Dev specifically.

Pattern: Controller audit

• Grep \[Route\("api/[a-z]+"\)\] enumerate ~30+ controllers
• Grep \[Authorize(Policy = "..." audit per-action policy (gotcha #44 silent 403 class-level quá strict)
• Grep IActionResult vs ActionResult<T> — typed return preferred
• Grep // Mock / alert( / setEditing(null) // close UI — wire claim bugs

Pattern: Memory cross-reference

16 memory entries tại C:\Users\pqhuy\.claude\projects\D--Dropbox-CONG-VIEC-SOLUTION\memory\ (S20 +2 turn 11/12):

• MEMORY.md — index
• project_solution_erp.md — cumulative narrative S1-S17
• feedback_per_chunk_commit.md — 5-chunk A-E discipline
• feedback_uat_skip_verify.md — Phase 9 skip test rule
• feedback_drastic_refactor_scope.md — defer dedicated session
• feedback_audit_reuse_before_clone.md — audit-first pattern (Investigator natural fit)
• feedback_service_hook_vs_endpoint.md — derived state hook pattern
• feedback_n_stage_workflow_pattern.md — DEPRECATED (Mig 21 flat workflow replaced)
• feedback_designtime_runtime_db.md — 2 LocalDB distinct
• feedback_md_compact_narrative.md — §6.5 KEEP narrative rule
• feedback_unittest_timing.md — §7 test timing
• feedback_cron_monthly_limitation.md — Cron SDK 7-day expire
• feedback_user_manual_style.md — non-tech docs style
• feedback_node_cicd.md — Node 20.x pin
• feedback_responsive_laptop_breakpoint.md — 4-tầng responsive pattern (S20 t11)
• feedback_multi_agent_setup.md — 3 sub-agents setup discipline (S20 t12)
• reference_session_prompts.md — canonical session start template

Pattern: External research priority sources

• anthropic.com/engineering/ (official patterns)
• cognition.ai/blog/ (Devin lessons)
• philschmid.de + eugeneyan.com + hamel.dev (senior engineers)
• learn.microsoft.com/en-us/aspnet/core/ (.NET 10 official)
• tanstack.com/query/latest (TanStack Query)

⚠️ Anti-patterns observed

• ❌ Skip MEMORY.md update before stop — lose knowledge tài sản
• ❌ Vague conclusion "seems like" / "probably" — em main rejects
• ❌ Missing file:line refs — non-verifiable evidence
• ❌ Exceed 500 words — em main reads too slow
• ❌ Scope drift to architectural recommendations — em main decides, not me
