6,329 models observed, hour by hour. 19 carry a signed proof that nothing was disclosed.
6,329 models observed across 168 hourly epochs; 168 anchored in Bitcoin; 19 signed silence proofs. Longest verifiable silence: 13.41 days (mistralai/Mistral-7B-v0.1). Every figure below is computed from files you can download and re-check: the epoch index, the target list, the proof index. Crovia records what was observed and what was not; it does not grade, rank or accuse.

What these numbers mean
13.41 days · mistralai/Mistral-7B-v0.1
Observed from 2026-09-19 18:00Z to 2026-10-05 06:00Z across 322 hourly epochs; in none of them did a training-data disclosure matching the published predicate appear on the model's monitored surfaces. The duration is bounded by the observations, not by the calendar. Model record · proof.
Observation-bounded, never wall-clock
A model is "silent" for the hours in which Crovia looked at its public surfaces and found no disclosure matching the predicate. Hours not observed do not count. The figure is a lower bound on what was checked, not a statement about what the provider did elsewhere.
One hour, one sparse Merkle root
Every hour the operator commits the set of negative observations to a depth-256 sparse Merkle tree, signs the sheet, opens it with a drand round and closes it with an OpenTimestamps receipt. How TACET works.
A Crovia Seal you can verify offline
Each proof wraps the non-inclusion paths for one model across its observed epochs in a crovia.seal.v1 object. pip install crovia-tacet-operator crovia-seal, then tacet-operator verify file.seal.json; or paste it in the browser.
374 epochs · 18,103 negative snapshots
6,332 models on the map since 2026-09-19 18:00Z; 372 epochs anchored; 153 Bitcoin-confirmed substrate anchors in the anchor list.
