Congress Mission source

# Congress MissionYour team's mission control at a medical congress. Plan who covers which sessions, share insights and flash alerts the minute they happen, message the team, and leave each day with the debrief already written. Phones link **directly to each other** over the same WiFi or a phone hotspot: no server, no accounts, nothing stored outside the team's devices.Live at [mafflab.xyz/apps/congress-mission/](https://mafflab.xyz/apps/congress-mission/). Installable, works offline, no cookies, no tracking, no generative AI.## What it does- **Control:** today's mission at a glance: your next session with a countdown, sessions running now and next with who is on them, coverage of priority sessions with one-tap "I'll cover", the latest flashes, the crew's status and location, and a live map of which phones are linked.- **Plan:** import the congress agenda (.ics from the congress app, or CSV), set priorities (P1 must cover, P2 should, P3 if possible), assign yourself, spot clashes and sessions nobody is covering, mark sessions covered.- **Intel:** capture an insight in seconds (data, expert view, competitor, unmet need, question for Medical Information), tied to the session, with a "so what". Mark it **Flash** and every linked phone sounds, vibrates and shows it. Teammates mark insights as seen.- **Comms:** team chat plus one-tap pings ("Need backup here", "Save me a seat"). A "Need backup" status alerts everyone.- **Debrief:** generated for any day or the whole congress: flashes, insights by theme, questions for Medical Information, sessions reported and missed. Copy as text, download Markdown or CSV, or print to PDF.- **Demo:** a fictional congress (AURORA 2026) with a simulated crew and fictional medicines, so anyone can try it alone.## How the phones link```  Laura's phone                         Javier's phone  1. shows an invite QR      ───────►   scans it (camera app or in the app)                                        2. shows a reply QR     scans the reply         ◄───────  3. WebRTC data channel, encrypted end to end (DTLS), over the local network  Priya pairs with Javier the same way. Laura and Priya then link by themselves:  their connection offers travel through Javier's phone, so nobody scans twice.```- **Pairing codes** (`mesh.js`) carry a compact form of the WebRTC session description: ICE username and password, the DTLS certificate fingerprint and the local candidates, plus the mission name and who is inviting. About 200 characters, so the QR code stays small enough for a phone to read from another phone's screen (version 10, 57 modules). Anything the compact form cannot hold is sent compressed instead. Codes work once, for 10 minutes.- **Mesh:** once linked to one teammate, a phone links to the rest automatically, with offers and answers relayed through linked phones. Every change is gossiped to all linked phones; if a direct link cannot form, data still flows through the others.- **Sync** (`store.js`): every record is a set of fields, and every field carries the hybrid logical clock of its last write. Copies merge field by field, newest clock wins (a last-writer-wins map, a simple CRDT), so phones that meet in any order end up identical. When two phones link they compare per-record digests and send each other whatever the other is missing, so a phone that was away catches up on relinking.- **No server.** By default nothing outside the team's phones is contacted, not even mafflab.xyz after the app has loaded. A setting, **Link across networks**, adds a public STUN server (Google) so phones on mobile data or different networks can try to link; messages still go phone to phone, but that server sees each phone's IP address.- **Relinking.** Phones send each other a heartbeat every 4 seconds and watch the connection state, so a dead link is dropped within about 15 seconds, and at once when the phone comes back from sleep or changes network. A link made by scanning codes always replaces any older link to the same teammate on both phones, so relinking works even while an old, dead link is still held. Messages that arrive before a link's handshake are kept, and each side confirms the handshake with a digest of its data so anything missing is sent again.- **Removing a teammate** marks them as removed: phones refuse their links and ignore changes they make afterwards.### What to expect at a real congress- Phones must be able to see each other on the network. Many congress and hotel WiFi networks isolate devices from each other; the reliable fallback is a **hotspot on one phone** that the others join.- A link lasts while the app is open and both phones are on the network. A short drop (a few seconds) heals by itself. After a longer one, both phones notice within about 15 seconds and show **Relink** (on Control, in Crew next to the teammate, and on the link indicator in the header): one of you shows a code, the other scans it with **Scan their code**. Either phone can show the code, and linking with any one teammate is enough, because the rest link through them. Everything written while apart is saved on each phone and syncs on relinking. "Keep the screen on" in Crew helps keep links up, at a battery cost.- Notifications while the app is in the background depend on the phone: Android keeps the app running for a while, iPhone suspends it quickly.- Each phone keeps the mission in the browser's storage. Export a backup now and then: it also moves a mission to a new phone, or syncs two phones that cannot link.- On iPhone, an invite scanned with the Camera app opens in Safari, which keeps its data separately from an installed home-screen app. If you installed the app, scan from inside it (Link, Scan their code).## Files```congress-mission/├── index.html, app.js, style.css, mafflab-theme.css├── store.js           records, clocks, merge, digests, calendar import (also runs in Node)├── mesh.js            pairing codes, WebRTC links, mesh relay, gossip sync (codec also runs in Node)├── demo.js            the fictional AURORA 2026 crew├── scan-worker.js     reads QR codes from camera frames with jsQR, off the main thread├── vendor/            qrcode-generator (MIT) and jsQR (Apache 2.0), unmodified├── manifest.webmanifest, sw.js, .htaccess, icons/, fonts/└── tests/    ├── store.test.js    convergence of 4 devices under random concurrent edits, clocks, removal, ICS and CSV    ├── signal.test.js   pairing codes for Chrome, Firefox and Safari style SDP, IPv6, fallbacks    ├── e2e.js           three phones pair by camera, form a mesh, sync, alert and catch up    ├── relink.e2e.js    WiFi drops (all packets cut with iptables), self-healing, relinking, dead old links    ├── phones.js        shared helpers for the two browser tests    └── fixtures/        SDP samples```## Tests```node tests/store.test.jsnode tests/signal.test.jsnode tests/e2e.js          # needs Playwright with Chromium, and ffmpegsudo node tests/relink.e2e.js   # also needs root, to cut the network with iptables```The relink test cuts every packet between two phones while both apps keep running, as when a phone leaves the WiFi, then restores it. It checks that 5- and 9-second drops heal by themselves; that after a long drop both phones notice, offer Relink and relink by scanning, three times in a row with either phone showing the code; and that relinking at once over a dead old link works, with the new link the one that stays.The end-to-end test runs three separate Chromium browsers, each with its own storage and its own fake camera. To scan, it screenshots the QR code on one "phone" and plays it to the other phone's camera as a video (ffmpeg), so the real scanner, the real codes and real WebRTC links are exercised. It covers pairing by camera, the automatic mesh link, flash alerts, a phone going away while the others keep talking, relinking and catching up, and identical data on all three phones at the end.Not tested here: real phones on real WiFi, Safari and Firefox (only their SDP formats are tested), and background behaviour on iOS and Android.## Limits- Phone-to-phone only: a teammate who never links with anyone never syncs (except by backup file).- Same network by default. Congress WiFi often blocks device-to-device traffic; use a hotspot.- Last writer wins per field: if two people edit the same session title at the same moment, one edit is kept.- Not a CRM or a regulatory record. Do not enter patient data, or names of healthcare professionals unless they spoke publicly on stage. Follow your company's insight-capture SOP.## LicenceMIT. © 2026 Aitor Martínez Rosell.

/* Congress Mission: the mission's data, kept on each device and merged when devices meet.   Every record is a set of fields, and every field carries the hybrid logical clock (HLC) of the   write that set it. Two copies of a record merge field by field: the newer clock wins. Merging is   commutative, associative and idempotent, so devices that exchange changes in any order, any number   of times, through any path, end up with the same data (a last-writer-wins map, a simple CRDT).

/* Congress Mission: devices talk to each other directly, with no server.   Pairing. Two phones exchange WebRTC connection details face to face: the inviter shows a QR code,   the new teammate scans it and shows a reply code, and the inviter scans that. Each code carries a   compact form of the SDP (ICE credentials, the DTLS certificate fingerprint and local candidates),   so it fits a QR code a phone can read from another phone's screen.   Mesh. Once a device is linked to one teammate, it links to the rest by itself: the connection   offers and answers travel through devices that are already linked. Every change is gossiped to all   linked devices, and on every (re)connection the two devices compare digests and send each other   whatever the other is missing (see store.js), so the team converges even with partial links.   Privacy. WebRTC data channels are encrypted end to end (DTLS). Codes are exchanged in person. No   server sees the data; by default no server is contacted at all, and devices find each other only   on the same network (WiFi or a phone hotspot). An optional setting adds a public STUN server,   which tells each device its public address so links can also form across networks. */(function (root) {  'use strict';  const S = root.CMStore || (typeof require === 'function' ? require('./store.js') : null);  const te = new TextEncoder(), td = new TextDecoder();  /* ======================================================== compact signal codec */  const TYPES = ['host', 'srflx', 'prflx', 'relay'];  const SETUPS = ['actpass', 'active', 'passive'];  const UUID = /^([0-9a-f]{8})-([0-9a-f]{4})-([0-9a-f]{4})-([0-9a-f]{4})-([0-9a-f]{12})\.local$/i;  function parseSdp(sdp) {    const L = String(sdp).split(/\r?\n/).filter(Boolean);    const m = L.filter(l => l.startsWith('m='));    if (m.length !== 1 || !/^m=application \d+ UDP\/DTLS\/SCTP webrtc-datachannel/.test(m[0])) return null;    const a = name => { const l = L.find(x => x.startsWith('a=' + name + ':')); return l ? l.slice(name.length + 3).trim() : null; };    const ufrag = a('ice-ufrag'), pwd = a('ice-pwd'), fpl = a('fingerprint'), setup = a('setup'), mid = a('mid'), port = a('sctp-port');    if (!ufrag || !pwd || !fpl || !mid || SETUPS.indexOf(setup) < 0 || (port && port !== '5000')) return null;    const [alg, hex] = fpl.split(/\s+/);    if (!alg || alg.toLowerCase() !== 'sha-256' || !hex) return null;    const fp = hex.split(':').map(h => parseInt(h, 16));    if (fp.length !== 32 || fp.some(x => !(x >= 0 && x < 256))) return null;    const cands = [];    for (const l of L) {      if (!l.startsWith('a=candidate:')) continue;      const p = l.slice(12).split(/\s+/);      if (p[1] !== '1' || p[2].toLowerCase() !== 'udp') continue;        // RTP component only, UDP only      const ti = TYPES.indexOf(p[7]);      if (p[6] !== 'typ' || ti < 0) continue;      const port = parseInt(p[5], 10);      if (!(port > 0 && port < 65536)) continue;      cands.push({ type: TYPES[ti], addr: p[4], port });    }    if (!cands.length) return null;    return { ufrag, pwd, fp, setup, mid, cands };  }  function fpHex(fp) { return Array.from(fp, b => b.toString(16).toUpperCase().padStart(2, '0')).join(':'); }  function buildSdp(o) {    const id = String(Math.floor(Math.random() * 9e15) + 1e15);    const out = ['v=0', 'o=- ' + id + ' 2 IN IP4 127.0.0.1', 's=-', 't=0 0', 'a=group:BUNDLE ' + o.mid, 'a=msid-semantic: WMS',      'm=application 9 UDP/DTLS/SCTP webrtc-datachannel', 'c=IN IP4 0.0.0.0'];    o.cands.forEach((c, i) => {      const tp = { host: 126, prflx: 110, srflx: 100, relay: 0 }[c.type];      const prio = tp * 16777216 + (65535 - i) * 256 + 255;      out.push('a=candidate:' + (i + 1) + ' 1 udp ' + prio + ' ' + c.addr + ' ' + c.port + ' typ ' + c.type + (c.type !== 'host' ?
