Sprint 123 Carry-Over Closure — i18n Component Completion + Sprint 118 P1 Security 3 Items + Oracle Infrastructure Stabilization + 2 Design ADRs

Sprint 124 — Sprint 123 Carry-Over Closure

Background

Sprint 123 completed only Phase A (component translation 48 files × 6 Waves), with Phase B~E carried over. Sprint 124 aims to close the 4 carry-over Phases (admin/studies page translations, Sprint 120 P1 security, i18n quality remaining, test infrastructure) while structurally resolving Oracle dispatch pipeline stability defects (Write blocking, unstable auto-critic chain, stale task loops).

Phase 0 — Housekeeping

  1. Branch rename: feature/sprint-123-phase-b-admin → feature/sprint-124-carryover
  2. Sprint 123 ADR commit (5500b06) — was 216 lines in untracked state
  3. audit-queue JSON path update: p1-024/p1-025 file fields updated to [locale] paths (reflecting Sprint 121 i18n refactoring)

Phase G — Oracle Infrastructure Improvements (~/.claude/oracle/, outside git)

Resolving Write blocking that recurred 6 times + 3 unstable auto-critic chain occurrences from Sprint 123.

#ChangeFile

G-3aGuarantee cd "${project_dir}" in cleanup trap + per-step log redirect (-critic.log, -reap.log, -dispatch.log)bin/oracle-spawn.sh

G-5[Additional fix] is_task_stale() — age > ORACLE_STALE_HOURS (default 2h) + no lock → auto-mark as cancelledbin/oracle-dispatch.sh

Phase B — i18n Component Completion (3 Waves, 18 commits)

B1 (5 commits, base 5500b06)

  • studies namespace newly created (15th)
  • studies/page (61) + studies/[id]/page (55) + studies/[id]/room/page (19) + studies/[id]/settings/page (111) translations
  • 154 new translation keys (ko/en)
  • Critic: merge-ready (L1 void useRouter, L2 Korean in tests — corrected in B2/Sprint 125 carry-over)

B2 (7 commits, base 5500b06)

  • admin / sharing / legal namespaces newly created (16th~18th)
  • guest under common.guest.* (avoid independent namespace)
  • admin/feedbacks (65) + shared/[token] (93) + privacy (54) + terms (51) + guest (16) translations
  • privacy/terms converted to async Server Component (SSR SEO optimization side effect)
  • B1 Critic Low (void useRouter) correction included
  • 151 new translation keys
  • Critic: ⚠️ Conditional → resolved via B2-fix

B2-fix (6 commits, base f6c7735)

  • 10 production toLocaleDateString/toLocaleTimeString('ko-KR') hardcodings migrated to useLocale()
    • Critic-identified 5 spots (admin/feedbacks 3, shared/[token] 2) + Oracle global grep 5 additional spots (studies/room AnalysisView/SubmissionView, submissions/analysis, submissions/status, analytics)
  • shared/[token] AI category safe lookup fallback (via t.has)
  • Critic: ✅ merge-ready

Phase C — Sprint 120 P1 Security 3 Items (2 Waves, 6 commits)

architect consultation (task-20260424-103725-44440)

  • Compared 4 options for p1-024 resolution (Middleware / Server Component / keep CSR / Hybrid cookie mirror)
  • Key finding: JWT is already stored as httpOnly Cookie (Sprint 120 migration complete) — corrected task premise
  • Recommendation: Option B (Server Component) — JWT_SECRET not exposed to frontend + SealedSecret unchanged + middleware.ts 100% compatible

C main dispatch (5 commits)

  • C-1 (p1-023): Add /shared, /privacy, /terms to middleware PUBLIC_PATHS
  • C-2a (infra): Add GATEWAY_INTERNAL_URL env (non-sensitive)
  • C-2b: New admin-guard.ts — requireAdmin(locale) Server util, cookies() + Gateway /auth/profile fetch + fail-secure redirect
  • C-2c (p1-024): admin/layout.tsx remove 'use client' → async Server Component migration → block non-admin bundle exposure
  • C-3 (p1-025): OAuth callback ALLOWED_ERRORS enum + 12 new translation keys

C-fix (1 commit)

  • Critic P2 finding: ALLOWED_ERRORS mismatches Gateway actual emit codes (access_denied/missing_params/auth_failed) — caused by Oracle consultation message error
  • Re-synced after measuring actual Gateway oauth.controller.ts:97-144
  • Removed 4 keys, added 3 keys

Phase D — i18n Quality + ADR Documentation (4 tasks, 6 commits)

Parallel Dispatch

  • palette D1+D2 (tier3, 7m) + scribe ADR (tier2, 1m) simultaneously spawned, separate panes
  • Phase G-4 is_agent_alive indicator working correctly in parallel confirmed

palette D1 (1 commit)

  • Zod schemas 4 (study/submission/problem/feedback) integrated with errorMap i18n
  • 12 new keys in errors.validation.* section
  • Applied tErrors() to 5 form usage sites + problem-form-utils + schemas.test.ts

palette D2a (1 commit)

  • lib/date.ts relativeTime(dateStr, locale='ko') parameter added
  • RELATIVE_LABELS map: ko + en support
  • useLocale() passed at 2 call sites

palette D2b (1 commit)

  • Removed hour12: true (shared/[token]:540, submissions/analysis:298)

scribe ADR 2 items

  • ADR-024 admin-server-guard.md (accepted) — Option B selection rationale + 4-option comparison table
  • ADR-025 gateway-oauth-error-normalization.md (proposed) — invalid_state dead code resolution proposal, Sprint 125+ implementation

D-hotfix (1 commit)

  • Critic P2 finding: problems/[id]/edit/page.tsx exposes raw validateProblemForm i18n keys
  • 5-line change (import 1 + declaration 1 + L540/591/623 tErrors wrapping)
  • Critic re-verification had API 529 Overloaded → Oracle spot approval (create/page.tsx pattern match confirmed)

Critic Chain Summary (7 rounds)

Sprint 118 Audit 25 Items Full Closure

  • Sprint 118 total findings: 25 (P0 17 + P1 8)
  • Sprint 119 (13 items) + Sprint 120 (4 items) + Sprint 124 Phase C (3 items) + existing false_positive (2 items) + other processing
  • At Sprint 124 close: completed 23 + false_positive 2 = 25 items 100% closed

Lessons Learned (Carry-Over to Sprint 125+)

Oracle Pipeline Follow-up Investigation

  • Short-task inbox Write permission issue (C-fix + D-hotfix + D-hotfix Critic): Even with --add-dir + bypassPermissions settings, agent self-log shows "Permission required to write result file." Normal for long tasks (7m+). Need to investigate specific claude -p runtime scenarios.
  • Critic API 529 Overloaded (D-hotfix): No auto-retry logic when Anthropic server overloaded during Critic auto-chain. Consider explicit flow for manual spot approval option on failure.

Sprint 125 Roadmap Additions

  • useRouter global locale-aware replacement (15+ files)
  • studies/[id]/room sub-component text translations (AnalysisView/SubmissionView/WeekSection)
  • problems/create/page.tsx, problems/[id]/edit/page.tsx self i18n unapplied Korean literals remaining
  • ADR-025 Gateway OAuth error code normalization implementation
  • 3 test files ko-KR hardcoding cleanup (NotificationBell/ReplyItem/CommentThread tests)
  • analytics namespace technical debt (dashboard → analytics)
  • admin-guard defaultLocale hardcoding removal (routing.defaultLocale reference)
  • FeedbackForm/FeedbackWidget useMemo (Sprint 123 Critic Wave A4 Low carry-over)
  • reviews.commentThread.replies EN plural ICU (Sprint 123 Critic Low carry-over)

False Positive Record (Sprint 124 Investigation)

  • B2-fix M-2 (submissions/analysis category fallback): CATEGORY_KEYS mapping-based fallback was already applied (line 498)

Final Namespace State: 18 (existing 14 + new 4)

account / analytics / auth / common / dashboard / difficulty / errors / feedback / landing / layout / problems / reviews / submissions / ui / studies / admin / sharing / legal
