Two findings from review:
1. callAI() previously accepted any model string from the client.
POST /api/hpi with { model: "openai/o1" } would call the reasoning
model regardless of whether the operator enabled it. Added
getAllowedModelIds() in src/utils/models.js (60s TTL DB-backed
cache) and a guard at the top of callAI() that rejects with
"model_not_permitted" when the requested ID isn't in the active
roster. No model supplied → silent fallback to DEFAULT_MODEL.
2. Middleware was updating user_sessions.last_activity on every
request, including GETs. Client-side polling (/api/auth/me
heartbeats, dashboard refreshes, log tail calls) kept sessions
alive indefinitely, defeating the 24h sliding idle policy. Now
only POST/PUT/DELETE/PATCH count as "user activity". GETs are
read-only and often automated — they no longer extend the
session. Idle enforcement still runs on every method, so a
24h-idle user still gets kicked on their next GET.
Middleware:
- Log to console.warn + audit_log when a session is killed for
inactivity. Shows up in Grafana/Loki so you can see how often
users actually get kicked. Audit action: 'session_idle_timeout'
- last_activity throttle bumped 5 min → 10 min — halves DB writes
per active user. Idle precision slop widens to 24h00-24h10;
still invisible in practice.
Per-user local-auth visibility:
- /api/auth/me now returns user.canLocalAuth: true when the stored
password is a real bcrypt / argon2 hash, false for the random
blob OIDC auto-creates for SSO-only users.
- Settings page hides "Change Password" and "Two-Factor
Authentication" sections when canLocalAuth is false — those UIs
are meaningless for users whose sign-in lives at the IdP.
- Password hash is not leaked in the /me payload.
Mobile (restating existing behaviour for clarity): no idle check,
365-day JWT in Keychain/Keystore, never auto-logs-out. Only logout
triggers are: manual logout, password change, admin revoke, JWT hit
365d, or app uninstall.
Session model:
Web — 24h sliding idle timeout enforced server-side via
user_sessions.last_activity. 30-day JWT + cookie are a
safety net; middleware is the real clock. Cookie is
re-set on active use so browsers match the sliding window.
Mobile — 365-day JWT, no idle timeout (stays persistent via Keychain
/ Keystore). Detected via User-Agent ("PedScribe" /
"Capacitor") or X-Client: mobile header.
2FA backup codes:
- 10 single-use codes generated when 2FA is first enabled
- Stored as bcrypt hashes in new users.totp_backup_codes column
- Consumed atomically on successful login fallback (when TOTP fails)
- Regenerate endpoint (POST /api/auth/2fa/backup-codes) requires
current password; invalidates prior codes
- Count endpoint (GET /api/auth/2fa/backup-codes/count) powers a
"N codes remaining" indicator on the 2FA settings card
- Modal shows codes exactly once with Copy + Download .txt actions
- Codes cleared when 2FA is disabled
New files:
src/utils/platform.js — isMobileClient() helper
Schema migration (idempotent):
ALTER TABLE users ADD COLUMN IF NOT EXISTS totp_backup_codes TEXT
- JWT_SECRET fails fast at startup in production
- CORS fails closed if APP_URL + CORS_ORIGINS are both missing
- Explicit HSTS (1y, includeSubDomains, preload)
- Rate limit sensitive auth endpoints (change-password, 2FA)
- /api/health now returns {ok:true}; details gated behind admin auth
- Login enumeration removed — generic 401 + dummy bcrypt on miss
- ReDoS guard: 20KB input cap on /suggest-codes
- showToast uses textContent, no innerHTML
- clearSession() clears service worker caches on logout
- OIDC state is now HMAC-signed and stateless (survives restart)
- SSRF guard on admin-set OIDC issuer (blocks private IPs, requires HTTPS)
Adds docs/mobile-build.md covering APK build, release, git push,
keystore, and troubleshooting for both PedScribe and PedsHub apps.
Security:

Audit logging:
- Add audit logging to all 24 PHI-handling endpoints across 13 route files
- Covers: generation, transcription, TTS, refine, encounters, documents, Nextcloud
- All fire-and-forget (no response delay)
AI improvements:
- Refine now includes original source material (transcript, notes, labs)
so AI can reference the full input when modifying output
- Add correction tracking (trackAIOutput) to sick visit and well visit tabs
- Fix sickvisit missing from encounter save noteIdMap
UI fixes:
- Non-blocking busy bar for transcription and AI generation (replaces full-screen overlay)

- Change domain to scribe.pedshub.com
- Fix PPTX export: add tables, bold/italic, numbered lists, code blocks, blockquotes
- Fix announcement banner close button (CSP was blocking inline onclick)
- Fix auth middleware: empty Bearer token now falls through to cookie auth
- Fix audio backups: only save on transcription failure, stop auto-deleting on success
- Soften AI correction injection to prevent model hallucination from correction history
- Fix LiteLLM TTS model name handling (no incorrect openai/ prefix)
- Expand AI instructions textarea in Learning Hub CMS
- Update README for v6 with all features and providers
- Add comprehensive docs/: architecture, API reference, database schema,
authentication, AI providers, speech, learning hub, configuration, deployment
REVERT: httpOnly cookie auth removed — reverts to JWT in localStorage.
The cookie implementation broke the login page (always-hidden auth screen).
localStorage token approach is restored fully:
- Login/register return token in JSON body
- getAuthHeaders() sends Authorization: Bearer header
- Session check reads localStorage token on load
- clearSession() removes localStorage token
Fix: slide preview padding — section elements now have 40px 48px padding
so text is not flush against the frame edges.
Kept from v3.14: AI panel context-aware options (word count, slide count,
quiz question toggle), delete confirmation wording per content type.
AI Generate panel:
- Content type synced from editor on open
- Article/Pearl: optional word count field
- Presentation: optional slide count field
- Questions row: checkbox toggle for article/pearl (optional), always on for quiz,
hidden for presentation; count input shown only when enabled
- Backend: passes wordCount/slideCount to prompt; questionCount=0 skips questions
Delete confirmation:
- Wording built dynamically from content type
- Presentation: no mention of questions
- Quiz: "All quiz questions will be permanently removed"
- Article/pearl: "Any quiz questions attached will also be removed"
Auth refactor — JWT → httpOnly cookie:
- Backend: setAuthCookie() sets ped_auth as httpOnly, Secure, SameSite=Lax, 7d
- Backend: clearAuthCookie() on POST /api/auth/logout (new endpoint)
- Backend: auth middleware reads ped_auth cookie first, falls back to Bearer header
- Login/register: no longer return token in JSON body; cookie is the session
- Frontend: getAuthHeaders() returns only Content-Type (no Authorization header)
- Frontend: session check uses /api/auth/me via cookie (no localStorage token)
- Frontend: clearSession() calls /api/auth/logout to clear cookie server-side
- Frontend: no token in localStorage; window.AUTH_TOKEN removed
- All FormData fetches use credentials:'same-origin' (cookie sent automatically)
- index.html: optimistic auth-screen hide (removed localStorage token check)
Tested: login, logout, /api/auth/me, admin routes, FormData uploads, cookie httpOnly
flag, 401 without cookie, cookie cleared on logout.
- New Learning Hub under Pediatric menu with content feed, category browsing,
search, content viewer, and interactive quizzes (MCQ, true/false)
- Quiz system with per-option wrong-answer explanations and general explanations
- Admin CMS for creating/editing categories, content (articles, pearls, quizzes),
and inline question builder with answer options
- 3-role system: admin (full access), moderator (can manage Learning Hub content),
user (all clinical features + learning hub read access)
- 5 new database tables: learning_categories, learning_content, learning_questions,
learning_options, learning_progress
- User progress tracking with score history per quiz
- Moderators see "Content Manager" tab instead of full Admin panel
