Two bugs under one roof.
The visible one: a publisher uploading anything over 10 MB on the live
site got "Network error — Unexpected token '<'" in the browser console.
Cause: the Caddy block I wrote for prometheus.x had
`request_body { max_size 2GB }` nested inside the handle block, where it
is a syntax Caddy parses but does not apply, so Caddy's own 10 MB
default was still the gate. Any oversize POST got Caddy's HTML 413 page,
which the browser's JSON parser choked on at the leading `<`.
Fix: moved `request_body { max_size … }` to the top of the prometheus.x
site block (outside `handle`), where Caddy actually honours it. The live
Caddyfile on p2pexchange is already patched + reloaded; a 50 MB upload
verified through the end-to-end path (Caddy → service → clamd → signed
scan report).
The scope one: 2 GiB was more than Prometheus should offer to publishers
at launch. Mobile apps are usually ~100 MB and even most desktop
installers come in well under 200 MiB. Dropping to 200 MiB:
- Fits every Android APK and most desktop installers.
- Shrinks the operator's Sia storage bill (fewer accidental Steam-size
uploads).
- Keeps the "publishers of larger binaries self-host and submit a
manifest with the external URL + SHA" escape hatch — the scanner
still fetches the URL and checks the hash, so a 5 GB game isn't
locked out, Prometheus just doesn't eat its storage.
Changes:
service/uploads.js MAX_FILE_BYTES default: 2 GiB → 200 MiB
service/pages.js /submit step-1 subtitle: "any size up to
2 GiB" → "up to 200 MiB"
deploy/prometheus-x.conf (unused angie fallback) 2g → 200m
deploy/apps-silentmode-st.conf (unused angie fallback) 2g → 200m
PROMETHEUS_MAX_UPLOAD_BYTES env still overrides per-instance.
Everything the VPS needs to run Prometheus is in Prometheus/deploy/:
prometheus-service.service systemd unit, Node on 127.0.0.1:3700,
ReadWritePaths narrowed to the dirs the
service actually writes (db, uploads, keys,
build). Hardened with NoNewPrivileges,
PrivateTmp, ProtectSystem=strict,
ProtectHome. Reads /etc/default/prometheus
for instance env (admin name, VT key,
payment config) so the repo carries no
per-install secrets.
prometheus-x.conf angie vhost for the BNS name's apex.
TLS-terminated with a self-signed cert that
the on-chain `tls` record pins (no CA
involved). Reverse-proxies / to the Node
service, 2 GiB client_max_body_size for
POST /api/upload, proxy_request_buffering
off so large uploads do not spool to disk.
make-tls-cert.sh ECDSA P-256, 10-year expiry (the on-chain
pin is what actually expires, not the cert
metadata). Prints the DER sha256 that goes
in the `tls` record. Idempotent — rerun to
rotate.
README.md First-time install recipe (useradd →
rsync → npm install --omit=dev → make-tls
→ angie reload → systemctl enable --now),
the matching Argus register.js command for
the record change, update + rollback.
Execution — the deploy itself, the record change, enabling payments —
is the operator's call, not something a script here runs on its own.
