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} · {cicd-monitor · verify 350b2bf deploy · verified-PASS · Run #369 ~4m13s + bundle DPPTx2Kw/CjoUEsoV + Mig 43 + health 200 ×4}.
• (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 Run #369 PASS (~4m13s · test 181 · bundle admin Krjvg_3j→DPPTx2Kw / user 6sNStgxa→CjoUEsoV · Mig stays 43 · health/smoke 200 ×4 · no anomaly).

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.
