Crovia records what AI providers disclose about training data, and the absence of it, as signed, Bitcoin-anchored facts. This repository is the public data plane of the Crovia substrate: hourly exports of observations and reports, weekly leaderboard snapshots, and the frozen experiments (CEPT, CRC-1, DSSE, Spider) from which the current registry grew.
It does not accuse, infer intent or judge compliance. It records what can be observed and verified.
| Path | Cadence | Source |
|---|---|---|
open/ (drift, forensic, reports, canon, signal, temporal) |
hourly | sync_from_server.sh on the production host |
snapshots/ (registry state, Merkle root, recent observations) |
hourly | same |
badges/, cep-capsules/ |
hourly when changed | same |
SYNC_STATUS.json |
hourly | same; last_sync is the timestamp to check |
leaderboard/<ISO week>/ |
weekly (Monday 02:13 UTC) | weekly_leaderboard.py; also mirrored at croviatrust.com/registry/data/leaderboard/ |
If last_sync in SYNC_STATUS.json is older than a few hours the sync has
stalled; the sync log on the host is /var/log/crovia/evidence_lab_sync.log.
(The sync was stalled from 2026-05-17 to 2026-09-19 by an orphaned
.git/index.lock; the backlog was pushed on 2026-09-19.)

curl -s https://croviatrust.com/api/registry/merkleHeadline figures (LACUNA records, days of documented silence, signed
observations, Bitcoin anchors) are defined in
CANON.md §4
and are recomputable from the public data files. Live silence figures come from
TACET (/registry/data/tacet/latest.json), not from this archive. Counts in this repository
(SYNC_STATUS.json, snapshots/registry_stats.json) are raw registry
counters, not the canonical headline figures.
