- **2026-06-08 (S50 P11-C Vehicle+Driver — HrmConfigs add-kind pattern VERIFIED on-disk, RAG down):** ⭐ **HrmConfigs KHÔNG có "kind enum/registry" backend** — 4 entity RIÊNG (LeaveType/Holiday/ShiftPattern/OtPolicy), NOT discriminated table. "kind" chỉ FE: `HrmConfigKind` union `fe-admin/src/types/hrm-config.ts:4` + route param. **Add 1 kind = mirror FULL entity stack 11 chỗ:** BE (1) Domain `Hrm/{X}.cs` AuditableEntity soft-delete (2) `Configurations/{X}Configuration.cs` `.ToTable+.HasIndex(Code).IsUnique()` (3) `ApplicationDbContext.cs:95-98` DbSet (4) `IApplicationDbContext.cs:102-105` DbSet (5) `HrmConfigFeatures.cs` +Region N (DTO+List/Create/Update/Delete handler+validator, mega 4-region :30/125/222/328) (6) `HrmConfigsController.cs` +4 route hardcode `[HttpGet/Post/Put/Delete("{kind}")]` (Post/Put/Del `[Authorize(Roles="Admin")]`, Get chỉ `[Authorize]`) (7) `DbInitializer.cs:2329 SeedHrmConfigsAsync` +if-block + skip-guard :2331 phải +`&& OtPoliciesNew.AnyAsync()` (8) `MenuKeys.cs:88-92` +const + `:149 All[]` (Admin auto-grant `SeedAdminPermissionsAsync` loop idempotent).

- **2026-06-07 (S50 wave `h2-verify` — B6 guardrail audit, read-only) [em main scribe from findings + H2 harvest]:** Verified B6 wave-isolation **3/3 PASS**. **B6 = TWO complementary rules:** (a) transient `wave-*/` + `agent-teams/` gitignored (`.gitignore:93-94`) → audit-noise=0; (b) canonical `agent-memory/**/MEMORY.md` TRACKED → rogue sub-write surfaces in `git status`. `git check-ignore -v` = ground-truth verifier BOTH directions (matched rule:line for ignored; empty for tracked). ⚠️ **Ordering gotcha:** wave/team patterns MUST sit AFTER `!.claude/**` (`.gitignore:82-83`) to win via last-match (`:91` documents intent) — else `!.claude/**` un-ignores everything. All 10 MEMORY.md tracked (roster 8→10). **Surprise (cross-cutting, both wave subs):** Bash tool = `/usr/bin/bash` NOT PowerShell despite env=PowerShell → `Get-ChildItem`/`Select-String`/`Test-Path` fail (exit 2/127); read-only Bash-only subs MUST use POSIX (`git ls-files`/`grep`/`ls`). Tag [wave-h2, b6-isolation, posix-not-pwsh].
