+# Session 48 — 2026-06-02 — adap-* verification closure post-restart + FD2 proof + Gov-v2 error-ledger
+
+> **User:** "làm xong hết đi rồi session-end luôn" (after `/session-start` + `/adap-apply all-pending` + `/adap-report all-applied`).
+> **Type:** governance/infra + 1 a11y fix (FE code). **No BE/DB/migration/test change.** Test 181 unchanged.
+> **Span:** 2026-06-02 (crossed into 06-03 at session-end).
+
+## Context
+
+S47 installed the AI_INFRA adap-* federated channel + adopted 3 broadcasts, all left at nấc **"executed → verified-pending"** (awaiting CLI restart — agent/command `.md` no hot-reload). S48 = the **post-restart verification session**: `/session-start` confirmed the restart already happened (this session's agent-registry contains `frontend-designer` + `adap-*` commands + 8 subs without `store_memory`), so the verified-pending items became provable.
+
+## `/session-start` bootstrap (S48)
+
+- Read CLAUDE.md + STATUS + HANDOFF + PROJECT-MAP + migration-todos(active) + workflow-contract + agents/README. RAG `list_projects` = **2413 chunks** (baseline ~2406, +0.3% drift OK), last-index 2026-05-29 (S41; S42-S47 = store_memory stopgap), rerank alive (top 0.89).
+- **Memory hygiene audit (S46 lesson):** 8 agent-mem files ≤16KB (cicd-monitor 15.8KB closest), 0 zero-byte; user-memory 16 .md, 0 zero-byte.
+- **Test gate ran live: 181 PASS** (58 Domain + 123 Infra, 0 fail/skip).
+- **Key finding:** S47 "restart pending" already DONE → registry has all S47 changes.
+
+## `/adap-apply all-pending` → `/adap-report all-applied`
+
+Outbox = 3 broadcasts, all 3 already had S47 adap-reports + committed (`72bbfa5`) → **0 new to apply**. Re-assessed + updated 3 reports honest (§C5 no-fake / G-015 no-overclaim):
+
+### #1 `Memory-store-memory-strip-global` → VERIFIED-runtime
+- SELF-CHECK: `grep store_memory` in agents `tools:` lines = **0** (only body/doc-notes). Loaded agent-registry grants **0 `store_memory` to all 8 subs** (incl. 8th frontend-designer, forked already-stripped).
+- **Honest caveat held:** NOT "subs read-only" — subs keep `Bash` (+ `Write/Edit` for write-roles). Real containment = defense-in-depth (git-diff + Qdrant chunk-count), not allowlist alone.
+
+### #2 `Agent-frontend-designer-floor` → agent-load VERIFIED + FD2 loop VERIFIED-RAN
+- Agent resolves in registry → frontmatter valid (`model: inherit` not `[1m]` gotcha #37 · `color: pink` · block-scalar desc · `effort: max` accepted).
+- **FD2 spawn-test (🩷 first real frontend-designer spawn, background):** full visual-verification loop on fe-user `/login` — read DS → `npm run dev` (Vite) → Playwright screenshot 375+1440 → **Read/viewed PNGs** → FD4 adversarial rubric (all PASS) → bounded fix → re-screenshot confirmed → `npm run build` PASS 0 TS error. 4 screenshot artifacts. Loop **genuinely ran**, not fake-verified.
+- **Fix:** `fe-user/src/pages/LoginPage.tsx:55` subtitle `text-slate-500`→`text-slate-600` (contrast ~4.6→~7.5:1 over translucent card, FD5 floor; on-scale, no magic number).
+- **em main mirrored** `fe-admin/src/pages/LoginPage.tsx:56` (identical subtitle) for 2-app parity (trivial 1-line → em solo per decision tree).
+- **Rig lessons (in FD MEMORY, reusable):** (1) Vite-dev `wait_until=networkidle` never fires (HMR ws) → use `domcontentloaded` + `wait_for_selector('form')`; (2) cold Vite first-goto triggers dep-optimize >15s → warm-up `goto` 60s before viewport loop. `webapp-testing` = Python Playwright (Chromium-for-Testing already installed). Bash tool = POSIX bash despite "PowerShell" env note.
+- **Project fact corrected:** SE = **Tailwind v4 CSS-first** — tokens in `fe-*/src/index.css` `@theme{}` (`--color-brand-600 = #1f7dc1`), **NO `tailwind.config.js`**. UI primitives = hand-rolled `cva` (`components/ui/{Button,Input,Label}`), not vanilla shadcn copy.
+- **Un-wired (quality-ADD, deferred):** FD4-rubric design-review gate via existing `reviewer`.
+
+### #3 `Governance-gov-v2-session-cmd-framework` → delta CLOSED (executed-file)
+- Core Gov-v2 5-axis + session-cmd 4-feature already VERIFIED-2way S44 (`ae30f8f`, AI_INFRA RT3); #6 echo-body + #7 plan-tree re-demonstrated this session.
+- **Open delta was:** no formal dedicated error-ledger + no explicit §L.b deterministic checklist. **CLOSED:**
+  - NEW `docs/governance/error-ledger.md` — blameless RCA (E-001 S46 0-byte · E-002 gotcha #57 Holiday UNIQUE · E-003 gotcha #44 silent-403 · E-004 gotcha #53 truncation) + **Active-Guards index** (2-strike promote + net-effect retire) + **§L.a deterministic-detect table AS-1..AS-9** (action-signatures, not AI-self-judgment) + **3-ledger triad mapping** (error-ledger=NEW · comms-ledger=`governance/README.md` adoption-ledger · summary-index=STATUS+session-logs).
+  - `.claude/commands/session-end.md` **Phase 1.5** = §L.a detect + §L.b 6-step (a→f) auto-maintain. Ran live this session (demo); auto from next session-end (command no hot-reload).
+
+## §L.b run this session (demo of the new keystone)
+- **(a) summary-index:** this STATUS Recently-Done + this session log.
+- **(b) Active-Guards:** "heavy-spawn→background" held (FD bg) · "lead=sole-RAG-writer" verified-runtime S48 · "session-end byte>0" wired+checked.
+- **(c) chore-flag:** 0 bloat (FD MEMORY ~4KB post-flush) · 0 zero-byte.
+- **(d) flush agent-memory — spawn-record:** `{frontend-designer · FD2 spawn-test fe-user/login · verified-RAN · 4 screenshots + build PASS + LoginPage.tsx:55 fix}`.
+- **(e) pending-request audit:** none placeholder.
+- **(f) harvest double-check:** FD = only spawn; MEMORY flushed + spawn-record captured ✓.
+- **§L.a detect:** 0 AS-hits this session (no `git add -A`, no `--no-verify`, no unfiltered-UNIQUE Mig, FD spawned background, no model-downgrade). Clean.
+
+## Verify
+- Build × 2: **fe-admin ✓ 8.92s · fe-user ✓ 559ms · 0 TS error** (chunk-size warnings pre-existing).
+- Tests: **181 PASS** (ran at bootstrap; FE-only change, no `.cs` touched → unaffected).
+
+## Commits
+- **C1 (docs/.claude, CI-skip):** 3 adap-reports + NEW error-ledger.md + session-end.md §L.b + FD MEMORY + STATUS/HANDOFF/session-log.
+- **C2 (code, CI-deploy):** `fe-{admin,user}/src/pages/LoginPage.tsx` contrast a11y → 🟩 cicd-monitor verify (bundle rotate + smoke).
+
+## Next
+- Confirm cicd deploy of login fix + new bundle hash (next session).
+- Product (anh pick): P11-C Vehicle+Driver (Mig 44) · gotcha #57 LeaveType/Shift filtered-unique (test-before) · P11-D/E/F · Phase 9 Ops.
+- RAG re-index S42-S48 (AI_INFRA op).
+- Note: FD agent self-labeled MEMORY "S47" (its creation-session); FD2 run was S48 — dates (2026-06-02) correct, session-number cosmetic.
