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drops withdrawn items before connecting, backs off and caps batches a day.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consent missing, outdated or withdrawn.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.
