Root cause of a downloaded/streaming video buffering repeatedly: every /files Range request
(a playing video fires dozens) re-ran the full attachment authorization, which scans the
messages table by attachment_id (un-indexed) — a per-chunk table scan = stutter. Now the
auth decision is cached per user+attachment for 60s (module-level, bounded), so range
requests after the first are ~free.
Also: preload='none' (nothing about a video downloads until the user taps play — only the
small poster loads), per 'no auto-download'. And the buffering spinner no longer hides on
canplay/loadeddata (they fire mid-buffer), so it reliably spins whenever it's buffering.

- Dockerfile: add ffmpeg (Alpine).
- static.js: new /thumbs/<id> — ffmpeg extracts the first frame (0.5s), caches it next to
the file, serves as the video poster (cosmetic; 404s gracefully if ffmpeg unavailable).
- static.js: /files now supports HTTP Range (206 Partial Content) + Accept-Ranges, which
iOS requires to stream/seek video reliably (fixes the buffer-before-play / multi-tap);
media (image/video/audio) now served inline, other files still download. Shared
attachment auth refactored into one helper used by /files and /thumbs.
- home.html: video poster points at /thumbs/<id>. build batch157.

- Message action pill gains a Forward button; tapping it enters selection mode
(tap bubbles to multi-select, footer bar shows count + Forward/Cancel, Esc exits).
- Forward picker lists EXISTING conversations only (DMs + groups from the sidebar),
searchable, multi-target. POST /api/messages/forward copies body+attachment into
each target (authorized as participant/member), live-pushed like a normal send.
- /files auth now accepts ANY message carrying an attachment (allByAttachment), so
forwarded images stay viewable for the new recipients.

Downloads/updates:
- config: DOWNLOADS_DIR (override to a mounted volume in prod).
- static.js: serves /downloads/* (installer, latest.yml, .blockmap) with range support for
resumable + differential auto-updates; /download/windows redirects to the current .exe
(stable link). Landing page gets a "Download the Windows desktop app" button (hidden in-app).
Install tracking (who installed the app):
- db app_installs + repos.appInstalls (upsert by install_id, fills in the user on sign-in).
- POST /api/v1/telemetry/install (records install + user once authenticated);
GET /api/v1/admin/installs (admin: list installs with user/version/os/last-seen).
- desktop main.js: stable per-install id in userData, exposed via preload
(bizConnectNative.installId/version/os); home.html reportInstall() posts it after login.
- e2e: +2 checks (telemetry recorded, admin sees it). 119/119. build batch20.

- manifest.json (standalone display, theme color, maskable icons 192/512).
- generated square icons + apple-touch-icon (180) from the logo.
- apple-mobile-web-app + theme-color meta in home.html.
- sw.js gets a no-op fetch handler so it meets installability criteria (still
no caching). static.js serves .json/.webmanifest with correct MIME.
- Installing as a PWA also unlocks Web Push on iOS (Apple requires Add to Home Screen).
Build marker -> pwa1.

Browsers were serving a cached old home.html on normal reloads (only incognito/
hard-refresh got the new one). HTML now sends Cache-Control: no-store; versioned
assets keep ETag revalidation. Bumps build marker to push4.

User-facing
- New post-login home (/home): chat rail + Share/Connect (embedded) + Meeting; login lives here when logged out
- Landing: "Log in with BizGaze" + no-login screen share
- Console replaced by a role-scoped Dashboard (/dashboard): admins see all team sessions, others see only their own; stats + CSV/PDF export
- Recordings saved as MP4 (H.264/AAC) with WebM fallback; old .webm still downloadable
- Fix: duplicate "Sign in" on the login card
Auth / integration
- BizGaze as identity provider: /api/login validates against BIZGAZE_LOGIN_URL (env-gated) and provisions a local user
- Phase 2 start: /api/v1 alias for all /api routes; Authorization: Bearer accepted across HTTP + WS; login returns a token (for native desktop/mobile clients)
Backend refactor (Phase 1, behavior-preserving)
- Split server.js into config/lib/session/presence/routes/static/signaling + repos (data-access) + bizgaze (service)
- All SQL behind repos.js, tenant-scoped (tenantId == team_id for now)
- e2e updated to current flow (21/21 pass before and after)
Docs: ARCHITECTURE.md (target architecture + phased plan), CLAUDE.md repo layout, .env.example BIZGAZE_LOGIN_URL
