RSS Feed
- /feed.xml proxies the Anchor feed under the site's canonical domain
- Rewrites channel <link> and atom:link self-ref to the site URL
- Served with 30-min Cache-Control, reuses the existing episode cache
PWA
- vite-plugin-pwa installed; Workbox service worker auto-generated on build
- manifest.json inlined in vite.config.ts (name, icons, theme, standalone)
- pwa-192.png and pwa-512.png generated from existing book_icon.png
- StaleWhileRevalidate for /api/episodes and /api/questions; CacheFirst for images
- API, feed.xml, and uploads routes excluded from navigate fallback
Lesson Comments
- Import and wire StudySectionComments into ColossiansStudySectionPage
- Replaces the CommunityBoard in the Lesson Discussion section
- All routes and moderation already existed; only the render was missing
Progress Tracking + Streaks
- Mark-complete handler now records lastStudiedDate, currentStreak, longestStreak on the user record
- Streak increments on consecutive calendar days, resets on a gap
- /api/study-account/overview now returns streak fields
- Account page: 4-stat summary row (notes, streak 🔥, longest streak, member since)
- Per-study progress bars showing completedLessons/totalLessons with gold → green fill at 100%

Newsletter nudge — was calling /api/study-account/profile (wrong endpoint, ignored subscription). Now correctly calls /api/study-account/preferences with PATCH.
Security:
Email regex — replaced the permissive [^\s@]+@[^\s@]+ pattern with a proper RFC-compliant regex in contact.js and downloads.js
Avatar magic bytes — server now checks actual PNG/JPEG/GIF/WEBP header bytes, not just the data URL prefix
Certificate rate limit — public /api/public/certificate/:token now has a 30 req/15min limiter
Session absolute TTL — admin sessions now have a 30-day hard cap; a stolen token can no longer be kept alive indefinitely by passive reads
Account lockout — 5 failed logins locks a study account for 1 hour
CSP headers — Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy headers added globally
Data integrity:
Cascade delete — deleting a study account now also removes their certificates, community posts, comments, and progress file
UX / reliability:
Escape key on modals — all 3 modal groups (study index, notes, account) now close on Escape
Display name min-length — empty spaces-only names rejected; if provided, must be ≥2 chars
Note save rate limit — 30 saves/minute per user max
Analytics fetch timeout — 5s AbortController so a hanging server doesn't block the browser indefinitely
Email validation on signup — frontend catches bad email formats before hitting the server
Cleanup:
Deduplicated download forms — StudyDownloadForm and ResourceDownloadForm now share a single DownloadForm base; both are now thin wrappers
Phase 1 — Quick wins:
- Image lazy-loading on series/resource cards
- Newsletter signup added to Episodes page (before highlights)
- Per-route meta tags via usePageMeta hook (title, og:title, og:description)
- Breadcrumbs on study index, section, and notes pages
- SVG completion checkmark badges on study section list
- Analytics time-range filter (7d / 30d / 90d) in admin panel
Phase 2 — Medium features:
- Related episodes on archived series detail pages
- Resource library two-tier filter (type + tag chips)
- Global search (Fuse.js) moved below sticky header as full-width bar
- Q&A anonymous upvoting with localStorage dedup + admin pin/unpin
- Study enrollment funnel tracking (firstVisitAt, firstCompletionAt) with funnel chart in analytics
Phase 3 — Larger features:
- Study section comments (auto-approve for enrolled users, admin moderation panel)
- Study completion certificate (canvas render, PNG download, shareable public URL)
- Episode script full-text search (mammoth docx extraction, server-side search, admin upload UI)
- Reflection questions renamed from Discussion Questions; quiz answers can be shared to section discussion
- Public certificate route at /certificate/:token with og meta tags
- Comment moderation panel added to admin under Manage > Study Comments
