Crovia — verifiable silence (TACET) and Crovia Seal

Live totals at this moment: epochs closed, epochs anchored in Bitcoin, models on the map, snapshot counts, signed silence proofs, and a pointer to the longest verifiable silence. No parameters. This is not a weekly Silence Report, not one model's record, and not a proof bundle. Reads published files only.

Which product is which. Crovia observes training-data disclosure. Causari is the code-provenance tool. No parameters. Use this, not explain and not crovia_status, when the question is the difference between the two. Reads no catalog.

The definition of one Crovia term. Allowed terms: tacet, silence, lacuna, seal, epoch, pnx, predicate, canon. Omit term, or pass an empty or blank string, to receive every definition. Any other value is an error listing those allowed terms, and it does not return the definitions. Use crovia_vs_causari, not explain, to tell the two products apart.

The published silence proof for one model: silence_days, observed window, epochs, seal id, URL, and how to verify it. model omitted or empty returns the proof index, not a bundle. include_bundle defaults to false; true attaches the crovia.seal.v1 bundle for that one model and does nothing on the index. This is not the live totals and not the weekly report. Reads published files only.

One model's observation: latest verdict, negative snapshots, anchored epochs, silence proof pointer, archive silence, badge and record URL. Required model is a Hugging Face id, org/name, for example Qwen/Qwen3-32B. An empty model is an error. An exact id is used; otherwise one case-insensitive substring match is accepted, and several matches return candidates instead of a verdict. This is not a catalog page, not the weekly report, and not the seal bytes. Reads published files only.

A page of observed model ids whose id contains query, compared case-insensitively, in catalog order, not a ranking. query omitted or empty matches the whole catalog and still returns at most limit rows. limit follows the historical rule: a missing, empty, zero or other falsy value is 25; any value int() accepts is then clamped into 1..100 (500 becomes 100, a negative becomes 1); a value int() cannot parse is an error and nothing is searched. returned and its compatibility alias count are the rows in this page. matched is how many ids match before the limit. catalog_total and its compatibility alias total_records are every record in the catalog, matching or not. limit is the limit actually applied. count is not the match count, and total_records is not the match count. This is not a verdict and not a proof. Reads published files only.

One published weekly Silence Report, or the latest report index. week is an ISO week YYYY-Www, for example 2026-W38. Omit week, or pass an empty string, to receive the latest index rather than one week's facts. A week that is not YYYY-Www is an error. A week with no published file is an error and names the index. This is not the live status and not one model's proof. Reads published files only.

Check a crovia.seal.v1 object or a wrapped TACET silence proof: signature, canonical bytes, bindings, and per-epoch non-inclusion paths. Pass seal as a JSON object or a JSON string, or url as an https://croviatrust.com/ address. With neither, the call is an error. Supplying url fetches that URL over the network. check_anchors defaults to false; true also checks the drand round bytes and the Bitcoin anchors over the network. A seal object with check_anchors false or omitted is checked from that object alone. This tool can reach the network, so it is not a closed-world call.
