Coverage is not a venue count. What makes cross-venue inference possible is that the same instruments are recorded across venues at the same time — so a model trained on one venue can be tested on another that shares none of its infrastructure. Below is what is recorded, and where each question stops being answerable.
Coverage
Grouped by asset class, because the first thing anyone checks is whether their own world is here. Resolution is the column that separates this from transaction-cost analysis: a full depth ladder says what was available, where a trade tape only says what happened.

On provenance.Data we recorded ourselves carries no redistribution constraint and cannot be bought by anyone else. Where a feed is licensed from a vendor, the history is deeper but the tape is not exclusive — and what may be shown back to you is governed by that licence. Both are stated per venue so neither is mistaken for the other.
Depth of history
The table above is what is recorded now, at current resolution. Behind it sits an earlier tape on three venues, kept because a model fitted on one regime and never tested outside it is not a model. It was captured at a different resolution, so it is reported separately rather than folded into the day counts above — the span and what was captured over it sit in adjacent columns, because those two are what vendors usually trade against each other quietly.
Recorded days are counted, not inferred from the span. Where the two differ, the recorder was not running on the days in between, and that is stated rather than smoothed into a range.

Where the answers stop
Every check has venues it cannot speak about. Those are reported as unknown and excluded from any total — never counted as passing. Book fragility is the check with gaps, and they are of two different kinds, which are kept apart below because only one of them can ever be closed.
Cannot be measured there
Not a hole in the recording. Ask a pool for its resting ladder and the question has no referent — so the honest answer is unknown, and it will still be unknown with a perfect recorder.
Venue
Why
xchain
Recorded here: pool screener, executions, Solana book, Solana quote. Price comes off a curve, so there is no queue to stand in and none to leave.
xstocks
Recorded here: pool screener, on-chain pool state, issuer NAV, Solana book. Price comes off a curve, so there is no queue to stand in and none to leave.
Not recorded there yet
The book exists; we capture a thinner slice of it. This is a recorder change rather than a limit, and it is listed so it can be asked for.
Venue
Why
helix
Recorded here: mark price, executions. What executed is captured; what was resting is not.
options
Recorded here: options quotes. Quotes are captured; the size resting behind them is not.
Why this page exists.A coverage page that lists only strengths tells you nothing, because every vendor has one. The useful half is this last section: it is the same principle the product applies to your fills, where a gap is named rather than passed, and where the difference between cannot and not yet is stated instead of being left for you to discover.
