playhorizon.dev now deploys from the private ludovic111/horizon-site, which holds website/'s history. The files
its build still reads from here move out of website/:
- the design tokens to crates/horizon-theme/tokens.css (xtask tokens writes them, tokens_css_is_up_to_date checks them);
- the roadmap's JSON to roadmap/roadmap.json (tools/roadmap.py build);
- the benchmark fixtures to crates/horizon-telemetry-server/tests/fixtures/benchmarks/ (the site keeps a copy);
- the web icons to docs/media/brand/web/ (xtask icons).
pr_ready loses its website area and the tokens special case; rust_changes, the roadmap's links and every doc
that pointed into website/ follow.

What players send (opt-in, unchanged switches) now describes the whole machine:
CPU cores and base/boost clock, the GPU's maker, integrated or discrete and its
VRAM, the drive under the game folder (NVMe/SSD/HDD), the screen (size, refresh,
scale), on battery or mains, laptop or desktop. Perf, crash and bug items carry
them in `system`; benchmark reports in `hardware`. No serials, host or user
names, or paths. CONSENT_VERSION goes to 2, so players are asked again.
The server keeps the new fields in `systems.extra` (the table is rebuilt once
on old databases, ids kept). /v1/aggregate and /v1/benchmarks/summary add
breakdowns by RAM class, VRAM class, drive, OS and integrated/discrete GPU;
a class is published only with at least 3 different installs, never a raw value.
website/scripts/benchmarks.mjs mirrors the classes on the shared fixtures.
The summary's "not Horizon or plain vanilla" check returned None (accepted)
instead of the rejection; it now matches the site's script.
The launcher's "View what would be sent" and `data show` list every field.

- DEFAULT_ENDPOINT is https://telemetry.playhorizon.dev. The heartbeat, the launcher's live count and the
outbox upload all go there; HORIZON_TELEMETRY_URL still names another server, and HORIZON_TELEMETRY_URL=off
sends nothing at all. CI workflows and the harnesses that start the game or the launcher set off. Consent
is unchanged: the four switches stay opt-in, only the anonymous ping is always on.
- GET /v1/benchmarks/summary: players' benchmark uploads grouped by GPU, CPU, render distance and game, groups
of 3+ installs only, medians per install then across installs, no install ID, day, OS version, driver,
memory or screen. Cached 10 minutes, CORS for the website. Same rules as website/scripts/benchmarks.mjs,
tested on the same fixtures; a deleted install leaves its groups at once.
- /v1/aggregate no longer lists the newest 50 raw benchmark reports (hardware, driver, day, one install each):
uploads are published only through the summary.
- Behind Railway's proxy the rate limit counts X-Real-IP, else the last X-Forwarded-For entry (the one the
proxy adds; a client could choose the first). Still in memory only, never stored or logged.
- crates/horizon-telemetry-server/railway.json: Dockerfile build from the repository root, health check
/healthz, one replica in europe-west4 (one SQLite file on the /data volume).
- Docs: docs/telemetry.md, the server README (the summary's shape, Railway setup), the privacy page (the ping
is on, where the data lives, how benchmark uploads are shown).

The game sends an anonymous ping once a minute while it runs (a random
session ID kept only in memory, the version, the platform, whether a LAN
or friends world is open). The telemetry server counts sessions seen in
the last 2 minutes, in memory only, with its own per-address rate limit
and a session cap, and serves rounded counts at GET /v1/live. The
launcher shows "N playing now" on the Play page when the count is
reachable, and tells players what the ping holds on the first-run
question, in Settings, and once on the Play page for players who
answered before. docs/telemetry.md and the privacy page say the same.
Like the rest of telemetry, nothing is sent until HORIZON_TELEMETRY_URL
is set or DEFAULT_ENDPOINT gets a server.

crates/horizon-telemetry-server, its own workspace like the launcher's (the
game's workspace never builds a web server):
- POST /v1/batch (zstd, decoded and checked by horizon-telemetry), DELETE
/v1/installs/<id>, GET /v1/aggregate (cached 10 min, CORS for the website),
GET /healthz.
- SQLite: machine descriptions stored once, one row of columns per session
with 80-byte summary blobs, zstd bodies for crash/bug/benchmark, daily totals
rebuilt when a day changes and kept after raw rows expire (180 days). About
190 bytes per session on disk.
- Per-address token bucket (addresses in memory only), per-install daily cap,
groups under 5 install-days hidden from the totals.
- Tests: refusals, rate limit, daily cap, deletion (rows and totals), retention,
storage size, and end to end with the launcher's uploader.
- Dockerfile and a path-filtered CI workflow.

horizon-telemetry, shared by the launcher, the game and the ingest server:
- consent.json in the game folder: four switches, all off until the player
answers, a consent version that re-asks when what is collected changes, the
answer's time, and a random install ID made at the first yes.
- Payloads: perf summaries (percentiles + 14 frame-time buckets from a
fixed-size Timings recorder), crash and bug reports, and benchmark reports
carried as docs/benchmark-report.md defines them; size caps per kind.
- A scrubber for user folders, user names, e-mail and IP addresses, UUIDs and
caller-known private terms.
- The outbox: only allowed kinds get in, daily caps, 200 items / 2 MiB.
- zstd batches with bounded decoding; the uploader re-reads the consent and
drops withdrawn items before connecting, backs off and caps batches a day.
- tests/consent_gating.rs: a local mock server sees zero connections with the
consent missing, outdated or withdrawn.
No server is set (DEFAULT_ENDPOINT is None): nothing is sent yet.
