Listing is free. The verdict is free. The history is free and public, for every endpoint, forever. What costs money is the cadence we measure you at, and whether we tell you the moment a condition flips. Nothing you pay for changes the result.
One row in this table is the whole design. The verdict is identical in both columns, and it always will be. Free applies to every endpoint we watch, with no cap and no account.
| Free | Paid | |
|---|---|---|
| The verdict | identical | identical |
| Public history | yes | yes |
| Recomputable record | yes | yes |
| Listing in the directory | free | free |
| Re-measured | once a week | every day |
| Told when a condition flips | no, you go and look | webhook, within the hour |
The alert does not fire on a single unreachable check. A network blip is not a failure, and a monitor that cries wolf once is never trusted again. It takes three consecutive unreachable measurements before anything is sent, and the record says which condition flipped and why.回線が1回詰まっただけでは鳴らない。3回連続で初めて1度だけ鳴る。何がどう変わったかまで書く。
Up to three endpoints on one subscription, because most operators run one to three servers and paying three times for that is silly. No setup fee, no minimum term, cancel any time. Prices are in US dollars and carry no Japanese consumption tax, because a service supplied to a customer outside Japan is outside its scope.
Every line here is enforced in the machine readable disclosure, not only in this sentence.
The gate cannot reach itself. A Worker cannot fetch its own hostname, so the operator's own gate entry reads held with http 522 and the reason in plain words. We left it on the list rather than dropping the one that fails.
The operator's other endpoints read pending, not verified, because determinism is never measured without consent and we do not consent on our own behalf either. If we wanted a green page we could have had one on day one.運営自身も緑ではない。自分の物差しで自分を測っているから。
A fix repairs one casting. The mould that cast it sits untouched unless somebody goes looking. This ledger records four things about a fix and freezes them: the class of assumption behind it, where the author searched for that same assumption, what they found at each location, and at what volume each casting failed. Append only. Every record carries a SHA-256 you can recompute yourself.
A record with an empty search list is accepted and published as such. An instance fixed with no class search is the exact thing this ledger exists to make visible. It is not rejected and it is not hidden. Those records are marked below.
This ledger verifies nothing. Each record says so in its own body: it is the author's own account, this gate did not reproduce it, and what is frozen is the claim and its date, not its truth.
Record one yourself — it is free, open to anyone, and it rates nobody. Read the ledger directly at GET /mould. The category was named by Federico Blanco Sanchez-Llanos in "The Mould, Not the Letter", 2026-08-20. The first entries here are our own, because we are not going to ask anyone else to go first.
