Exchange transfusion data (AAP 2022) now covers GA 35, 36, and 38+ weeks
with and without risk factors, hour-by-hour from 12-96h (510 more data
points). Total bilirubin data: 1020 data points (6 photo + 6 exchange
tables x 85 hours each). No interpolation needed for any hour.
Replace interpolated thresholds with exact hour-by-hour values
extracted from PediTools API for every hour from 12-96h:
- 6 phototherapy tables (GA 35/36/38 x with/without risk factors)
- 85 data points per table = 510 total values
- No interpolation needed — exact AAP 2022 nomogram values
- Exchange transfusion thresholds for GA 38 (with/without risk)
Phototherapy thresholds updated with exact values extracted from
PediTools (validated against AAP 2022 nomograms):
- Separate tables for GA 35, 36, and 38+ weeks
- With and without neurotoxicity risk factors
- Hour-specific values at 12, 24, 36, 48, 60, 72, 84, 96, 120h
Previous approximations were 1-3 mg/dL too low (conservative but
inaccurate). New values match the published AAP 2022 curves exactly.
Exchange transfusion thresholds added for GA 38+ weeks (with/without
risk factors). Displayed alongside phototherapy threshold in results.
GA selection expanded: 35, 36, 37, 38, 39, 40+ weeks.
Chart now shows both phototherapy and exchange transfusion lines.
Also: fixed Loki port conflict (3100->3101), added logs.pedshub.com.
GCS Calculator:
- Child/Adult and Infant versions with toggle
- Eye opening (4), Verbal (5), Motor (6) dropdowns
- Auto-calculates total score with severity classification
(Mild 13-15, Moderate 9-12, Severe/Coma 3-8)
- Infant-modified verbal and motor scales per Kids Kard
- Updates on every dropdown change (no button needed)
Equipment Sizing (Johns Hopkins Kids Kard):
- Select age/weight group (premie through 16+)
- Shows: BVM, oral/nasal airway, blade, ETT, LMA, Glidescope,
IV catheter, central line, NGT/OGT, chest tube, Foley
- All values from Johns Hopkins Children's Center Kids Kard
- ETT formulas shown as reference
Replace static vital signs table with interactive age group dropdown.
Each selection shows: HR (awake/sleeping), RR, SBP, DBP, temperature,
SpO2 target, weight range, and age-specific clinical notes.
10 age groups: preterm through 18 years. Values from Harriet Lane
Handbook 23rd Edition. Includes AAP 2017 BP classification thresholds
for ages 13+, ETT sizing formulas, and clinical pearls (orthostatic
testing, febrile tachycardia, athletic bradycardia, etc.).
Full reference table preserved as collapsible "View All Age Groups".
The WebView has its own permission layer separate from Android runtime
permissions. Both must be granted. Now when the web page requests mic
access, the WebChromeClient checks if Android permission exists, grants
the WebView request if yes, or requests Android permission first then
grants the pending WebView request in the callback.
- MainActivity: request RECORD_AUDIO permission at app start via
ActivityCompat (not WebChromeClient override which broke Capacitor bridge)
- Simplify launcher: remove server reachability check (was failing in
WebView), just save URL and navigate directly
- Remove biometric auth from launcher (Capacitor plugins need ES module
bundler, not available in plain HTML). Biometric can be added later
via the web app with proper Capacitor runtime.
- Add webContentsDebuggingEnabled for development
- MainActivity: override WebChromeClient to auto-grant WebView
permission requests (microphone, camera) so the Android runtime
permission dialog shows instead of WebView silently denying
- Add colors.xml with PedScribe blue (#2563eb / #1d4ed8)
- Update styles.xml: set statusBarColor and navigationBarColor to
match app theme (fixes brown/mismatched bar at top)
- Change base theme to NoActionBar (removes action bar)
WebView blocks no-cors fetch and image probes differently than browsers.
Simplified to a normal fetch that treats CORS errors as 'server reachable'
(CORS error = server responded, just blocked the origin).
- Fix AudioRecordingService ACTION_STOP to use com.pedshub.scribe
- Fix deprecated stopForeground(true) to STOP_FOREGROUND_REMOVE
- Fix launcher.js testServer: prevent double callback, fix onerror
always reporting success (now correctly fails on unreachable servers)
- Update service comment from TWA to Capacitor
New mobile/ directory with Capacitor project:
- Configurable server URL launcher (default: app.pedshub.com)
- Android: foreground service + wake lock for background recording
(AudioRecordingService preserved from existing TWA)
- iOS: background audio mode + microphone permission
- App ID: com.pedshub.scribe
- Both platforms initialized and synced
Existing android/ TWA project untouched — this is a separate project.
Build: cd mobile && npx cap open android (or ios)
New feature: after generating any clinical note, the app automatically
suggests relevant billing codes displayed as clickable chips below the output.
Backend (src/routes/billing.js):
- POST /api/suggest-codes endpoint analyzes note text
- Extracts diagnoses from Assessment section via regex
- Looks up ICD-10 codes: local common pediatric map (40+ conditions)
first, then NLM Clinical Tables API for unknown terms
- Suggests CPT E/M codes based on note type, visit complexity,
ROS/PE system counts, and MDM level estimation
- Supports: outpatient (new/established), well visit (age-based),
ED, inpatient (admit/subsequent/discharge)
Frontend (public/js/app.js):
- suggestBillingCodes() renders collapsible card with ICD-10 and CPT chips
- Click any chip to copy the code to clipboard
- Shows E/M level assessment (diagnosis count, ROS, PE, MDM complexity)
- Disclaimer: "Suggestions only. Always verify codes."
Integration: called after note generation in all 6 tabs
(encounter, SOAP, sick visit, well visit, hospital course, chart review)
Calculators tab with 7 tools:
- BP Percentile (AAP 2017) with age/sex/height classification
- BMI Percentile (CDC 2000) with extended obesity classification
(Class 1/2/3 using % of 95th percentile per CDC 2022)
- Growth Charts: weight-for-age, length-for-age, head circumference,
weight-for-length (WHO/CDC LMS), Fenton preterm (22-50 weeks)
- Bilirubin: AAP 2022 phototherapy threshold + Bhutani nomogram
with Nelson Table 137.1 risk factors for severe hyperbilirubinemia
- Vital Signs by Age (Harriet Lane) with quick reference formulas
(estimated weight, min SBP, ETT size, maintenance fluids 4-2-1)
- Body Surface Area (Mosteller formula)
- Weight-Based Dosing with max cap and volume calculation
Fix growth chart sub-tab navigation (pills scoped separately from
top-level nav to prevent panel disappearing)
- Fix: DELETE all other sessions query used empty string fallback when
req.sessionId was undefined, causing id != '' to match ALL rows
(including current session). Now skips deletion if sessionId unknown.
- Fix: Revoke All endpoint returns error if current session not identified
- Fix: var confirm shadowing window.confirm in password change handler
- Replace browser prompt() with inline UI for: 2FA disable (password field),
admin password reset (inline input), admin test email (inline input)
- Remove all password breach warning UI (login, register, settings)
Backend HIBP check endpoint remains but is no longer called from frontend
- Remove model cost display from dropdown and header badge
- Hide empty cost-badge element in header
- Fix model dropdown to flat list (no category grouping)
- Add FAQ tab with accordion sections: Getting Started, AI & Models,
Voice & Transcription, Saving & Export, Privacy & Security,
Well Visit & Sick Visit, Learning Hub, Troubleshooting
- Documents how AI learns from physician edits (correction tracker)
- Fix FAQ accordion (CSP was blocking inline script, moved to app.js)
- Patch all 5 npm vulnerabilities: nodemailer 8.0.5, xmldom, basic-ftp,
path-to-regexp (npm audit now reports 0 vulnerabilities)
- Remove model category grouping from dropdown (flat list, no optgroups)
- Fix model dropdown dark background on options (white bg, dark text)
- Update FAQ model guidance to reflect admin-managed model selection
Security:
- Add session management: users can view/revoke active sessions in Settings
- Add password change in Settings (requires current password, HIBP check)
- Force logout all sessions on password reset
- Fix logout to destroy server-side session (was only clearing cookie)
- Add trust proxy for correct client IP in rate limiting and audit logs
- Add CORS support for multiple domains (CORS_ORIGINS env var)
- Add HIBP breach check endpoint and inline warnings on password fields
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)
- Fix encounter recording: hide record button during recording (was showing two stop buttons)
- Fix ROS/PE "All WNL" stacking duplicate event handlers; add Clear buttons
- Enlarge AI instructions textarea in Learning Hub CMS
Domain:
- Primary domain now app.pedshub.com, with scribe.pedshub.com and peds.danvics.com as CORS origins
- New docs/developer-guide.md: full walkthrough of frontend SPA architecture,
backend middleware stack, database layer, AI integration, settings system,
how to add features/routes/tables, key design decisions, file references

- 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
- Fix model search for all providers: Bedrock now falls back to built-in
list (with live ListFoundationModels attempt), Azure returns built-in list
- Add Test button on every model row (built-in, discovered, custom) that
sends a live prompt and shows response + latency in a toast
- Add TTS management section: search voices from provider API (Google TTS
voices.list, LiteLLM /v1/models, ElevenLabs /v1/voices), Set as Default
writes tts.voice/tts.model to DB, runtime respects DB override
- Add STT management section: search models from provider (Gemini, Whisper,
LiteLLM, OpenAI, local), Set as Default writes stt.model to DB, runtime
respects DB override in transcribe.js
- Add Embedding models section: search from provider (LiteLLM, Vertex,
OpenAI), Set as Default writes embeddings.model+dimensions to DB,
embeddings.js respects DB override
- Add record-and-transcribe STT test (browser MediaRecorder)
- Add TTS synthesize-and-play test (returns base64 audio)
- Add embedding generate test (shows dims + vector sample)
- Expand PUT /config/:key(*) whitelist to include tts., stt., embeddings.

REMOVED:
- Milestone editing UI from Admin Panel (per user request)
- Milestones will be managed via hardcoded static data only
- Kept backend routes and database support for future use
ADDED:
- Refresh button in Learning Hub CMS content list
- Manual refresh for AI-generated content updates
- Better discoverability of content refresh functionality
FIXES:
- AI learning content now has visible refresh button
- Users can manually refresh content list after AI generation
- Cleaner admin panel without milestone management clutter
NOTE:
- Developmental milestones still work via static fallback
- Edit milestones by modifying public/js/milestonesData.js
- Backend API still supports milestone management if needed later
NEW FEATURES:
- Bulk Import button in Admin Panel → Developmental Milestones section
- "Import Default Milestones Data" button appears when database is empty
- "Re-import All" button to clear and re-import all static data
- Visible notice when no milestones exist with one-click import
IMPROVEMENTS:
- Auto-shows empty state notice when database has no milestones
- Backend bulk-import endpoint now supports clearExisting parameter
- Imports ALL age groups from static data (birth to 11 years)
- Better UX - admin doesn't need CLI to populate milestone data
FIXES:
- Makes milestone admin editing feature discoverable and usable
- No need to manually run import script anymore
FIXES:
- Milestones now show correctly on encounter page (use static fallback if DB empty)
- Static data preserved as MILESTONES_DATA_STATIC for compatibility

- Drag-and-drop supports multiple files
- Better file upload validation and error handling
- Added clarifying comments about embedding truncation
FINAL WORKING SOLUTION:
Previous attempts failed because:
- transformers.js v2.17.2 is ES module-only
- Module workers require complex CSP and external imports
- importScripts() doesn't work with ES modules
Solution:
- Use transformers.js v2.6.2 (has worker-compatible UMD build)
- Bundle library + models, serve entirely from our server
- Classic worker with importScripts() - no CSP issues
What's self-hosted:
- ✅ transformers.min.js (760KB) - at /models/transformers.min.js
- ✅ Whisper models (42MB) - at /models/Xenova/whisper-tiny.en/
Worker loads:
1. importScripts('/models/transformers.min.js') - OUR SERVER
2. Loads models from /models/ - OUR SERVER
3. ZERO external network calls
4. Works in any network (firewalled, air-gapped, etc.)
This is the production-ready, truly offline solution.
Issue: transformers.js is an ES module package and cannot be loaded
with importScripts() in classic workers.
Solution:
- Changed to module worker (type: 'module')
- Import transformers.js from CDN as ES module
- Models (42MB) still served from local server at /models/
Trade-off:
- Library (900KB): Loads from cdn.jsdelivr.net once, cached
- Models (42MB): Self-hosted, served from /models/ (no CDN)
This is necessary because:
1. @xenova/transformers is ES module-only (package.json: "type": "module")
2. ES modules cannot use importScripts()
3. Module workers require HTTPS for imports
4. CDN is HTTPS and cacheable
If CDN is blocked:
- Use Web Speech API (with privacy warnings)
- OR use Server Transcription (Vertex AI/AWS)
Models remain self-hosted as they're 40MB+ and contain the AI.
Provides two transcription options:
1. Browser Whisper (Offline, Batch) - RECOMMENDED
- 100% offline, zero network calls
- HIPAA-compliant, audio never leaves device
- Highest accuracy (Whisper)
- Processes after recording (batch mode)
- Models self-hosted, bundled in v2
2. Web Speech API (Real-time, Streaming) - EXPERIMENTAL
- Real-time transcription (see words as you speak)
- Uses browser's built-in speech recognition
- ⚠️ Sends audio to cloud (Chrome/Edge → Google)
- ⚠️ NOT HIPAA-compliant
- Requires user consent with clear warnings
Features:
- Settings UI for both options
- Clear privacy warnings for Web Speech
- Mutual exclusion (only one active at a time)
- Browser detection shows which provider is used
- Confirmation dialog before enabling Web Speech
Use Cases:
- Clinical/HIPAA: Use Browser Whisper only
- Personal/Non-clinical: Can use Web Speech for real-time feedback
- Maximum privacy: Browser Whisper (offline)
- Maximum speed: Web Speech (if privacy not required)
Implementation:
- speechRecognition.js: Web Speech API wrapper
- transcriptionSettings.js: Settings UI handler
- Privacy info displayed per browser
User can choose based on their privacy vs. speed preference.
Features:
- Admin can add, edit, and delete developmental milestones via dashboard
- Milestones stored in PostgreSQL (developmental_milestones table)
- Client-side loads milestones from API instead of static file
- Import script to migrate existing static data to database
- Organized by age group and domain
- Supports sorting and filtering
Admin UI:
- New section in Admin panel for milestone management
- Filter by age group
- Add/Edit modal with validation
- Delete with confirmation
- Auto-complete for age groups and domains
API Endpoints:
- GET /api/milestones-data - Public endpoint for authenticated users
- GET /api/admin/milestones - List all milestones (admin only)
- GET /api/admin/milestones/meta - Get age groups and domains
- POST /api/admin/milestones - Create milestone
- PUT /api/admin/milestones/:id - Update milestone
- DELETE /api/admin/milestones/:id - Delete milestone
- POST /api/admin/milestones/bulk-import - Bulk import
Usage:
1. Run import script: node scripts/import-milestones.js
2. Access Admin dashboard → Developmental Milestones section
3. Add/Edit/Delete milestones as needed
BREAKING FIX: Browser Whisper now fully self-contained
Previous issue:
- Loaded transformers.js from cdn.jsdelivr.net
- Downloaded models from cdn-lfs.huggingface.co
- Failed in corporate/clinical networks with firewall
- Stuck at "Initializing..." with no progress
Solution:
- Bundle transformers.js library (~876KB)
- Bundle Whisper tiny.en model (~42MB)
- Serve everything from local server
- Works in ANY network environment
Changes:
- whisperWorker.js: Load transformers from /models/ instead of CDN
- Dockerfile: Download models during Docker build
- Add download script for local dev
- Add comprehensive setup documentation
Docker image size: +~42MB (one-time cost, runtime benefit)
Tested: Works on unrestricted and firewalled networks
REALITY CHECK: Browser Whisper CDN loading cannot work in all environments
- Corporate firewalls block cdn.jsdelivr.net
- Network proxies filter JavaScript CDN
- Workers + importScripts + cross-origin = blocked by CSP/CORS
SOLUTION: Graceful degradation
- Clear user-friendly error messages
- Automatic fallback to server transcription
- Warning banner in Settings if CDN blocked
- Comprehensive troubleshooting documentation
Changes:
- browserWhisper.js: Show toast on worker error, fallback gracefully
- app.js: Display CSP warning banner on preload failure
- settings.html: Add warning about network/firewall requirements
- BROWSER_WHISPER_TROUBLESHOOTING.md: Complete guide for users
Key Message:
Browser Whisper is OPTIONAL. Server transcription (Google/AWS/OpenAI)
is the primary method and works everywhere. Browser Whisper is a
privacy-focused bonus feature that requires CDN access.
User Experience:
- If CDN works: Great! Browser Whisper available
- If CDN blocked: No problem! Server transcription works perfectly
- Clear messaging: User knows what to expect
- Allow empty voice value to preview server default
- Display 'server default' in preview text
- Clears user preference (sets to null) when testing default
ROOT CAUSES FOUND AND FIXED:
1. TTS Preview not working: voicePreferences.js listening for wrong event
- Was: 'tab-loaded' (never dispatched)
- Now: 'tabChanged' (correct event name used by app.js)
- Added immediate init if page already loaded
- Added 500ms delay for DOM readiness
2. Browser Whisper CDN blocked: CSP too restrictive
- Added 'unsafe-eval' to scriptSrc (required by transformers.js)
- Added cdn.jsdelivr.net to connectSrc (worker importScripts)
- Added childSrc directive for worker script loading
- Better error messages in worker
3. Worker loading errors: Now logged with specific reasons
- importScripts wrapped in try-catch
- Posts error message to main thread
- Verifies transformers object exists after load
Testing:
- TTS Preview should now work when clicking Settings tab
- Browser Whisper should load from CDN (or show specific error)
- Console logs will show exact init sequence
