Map tile styles. The default /{z}/{x}/{y}.jpg route serves OpenStreetMap (the firmware default). An opt-in OpenTopoMap topographic style is served from /opentopo/{z}/{x}/{y}.jpg (explicit OSM alias at /osm/...); the device requests it only when the user enables Map → Options → Topographic map. Legal: OpenTopoMap map tiles are © OpenTopoMap (CC-BY-SA) over © OpenStreetMap contributors (ODbL) + SRTM — the touch UI shows that attribution when topo is active, and the 14-day disk cache keeps each tile hitting OpenTopoMap at most once per fortnight (their tile-usage policy asks for a contactable UA + caching, both of which the transcode service provides). Deploying the topo routes = update tiles.wadamesh.com.conf + tile-transcode.py, then systemctl restart wadamesh-tile-transcode && nginx -t && systemctl reload nginx and purge the Cloudflare cache for tiles.wadamesh.com/opentopo/*.

The firmware fetches tiles + the update-check over plain HTTP (on-device HTTPS isn't viable — mbedTLS needs ~30 KB heap, only ~5 KB is free post-Wi-Fi), so the tile + firmware hosts must stay reachable over HTTP. Cloudflare provides the edge cache, HTTPS for the flasher, and hides the origin IP (so no IP lives in this repo or the firmware).

1. VPS (origin)

sudo apt install nginx
sudo mkdir -p /srv/wadamesh/firmware/releases/TOUCH /var/cache/nginx/wadamesh-tiles
sudo cp deploy/nginx/tiles.wadamesh.com.conf    /etc/nginx/sites-available/
sudo cp deploy/nginx/firmware.wadamesh.com.conf /etc/nginx/sites-available/
sudo ln -s /etc/nginx/sites-available/tiles.wadamesh.com.conf    /etc/nginx/sites-enabled/
sudo ln -s /etc/nginx/sites-available/firmware.wadamesh.com.conf /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx

2. Cloudflare

DNS: A/AAAA records for tiles, firmware, flasher, @ → the VPS IP, all Proxied (orange cloud).
SSL/TLS: mode Flexible (CF↔origin HTTP) is enough since the origin is HTTP-only. Do NOT enable "Always Use HTTPS" on tiles. or firmware. — the firmware needs plain HTTP there.
Cache Rules:
- tiles.wadamesh.com/* → Eligible for cache, Edge TTL ~14d.
- firmware.wadamesh.com/releases/*/*.bin → cache, Edge TTL ~1d.
- firmware.wadamesh.com/releases/TOUCH (the listing) → short TTL (~60s) or Bypass, so new releases appear promptly.

3. Publishing a release

From a wadamesh checkout (builds both boards, refreshes the listing, rsyncs up):

WADAMESH_VPS=user@your-vps scripts/release.sh beta_2

The on-device check GETs http://firmware.wadamesh.com/releases/TOUCH, finds the highest beta_<N>, and (once OTA-over-Wi-Fi is re-enabled) pulls …/releases/TOUCH/beta_<N>/<board>.bin.

Done

Web flasher ✅ at flasher.wadamesh.com — deploy/flasher/ (esp-web-tools / Web Serial, board picker, manifests pointing at the rolling /latest/ merged bins; release.sh refreshes /latest/ each publish).
Apex wadamesh.com 301-redirects to the flasher — activate by pointing the wadamesh.com A record at the VPS in Cloudflare (it's still on the parking IP).

TODO before public launch

Re-enable OTA-over-Wi-Fi in the firmware (currently it version-checks then defers to manual flashing).
Flip wadamesh repo public = launch.
Decide tile-proxy sharing: dedicated tiles.wadamesh.com (this config) vs reusing the meshcomod proxy.

Never commit the VPS IP, SSH keys, or WADAMESH_VPS. Cloudflare fronts the origin; the deploy target is supplied via the environment at publish time.
