{"what_this_is":"The mechanism of this store in one document: how a claim about somebody else's endpoint is made, signed, chained and published so a third party can check it without trusting us, and what happens to your money if you buy our labour on top of it.","what_you_can_use_it_for":"Deciding whether to rely on anything this store publishes, and on what terms. It is written for a caller who has never been here, needs to know what kind of thing an observation is before citing one, and wants the failure modes named before it spends. Nothing here narrows what you may do with the record: it is free, complete, and licensed for reuse, including by people building something that competes with us.","what_this_is_not":"Not a rating, a score, a ranking, or a certification, and not an escrow, a guarantor, or a dispute court. Those last three absorb the risk between payment and delivery and need a balance sheet; this store observes that gap, signs what it saw, and publishes it. A verdict here is one dated observation of one moment, which expires and is re-taken — never a standing judgement about an operator.","how_evidence_is_made":[{"step":1,"name":"The knock","what_happens":"Once a week the round walks the public x402 discovery feeds and sends one plain GET to every door they name. No authentication is bypassed, no rate limit is evaded, and nothing private is read.","what_you_can_check":"The feeds are public and so is the door list: /doors.json names every host ever seen, and every host page carries the weeks we did NOT reach it, with the reason."},{"step":2,"name":"The reading","what_happens":"The bytes that came back are run through a named battery of checks. Each check has a published name, so two instruments can mean the same thing by the same word, and a check that cannot run says so instead of passing.","what_you_can_check":"The vocabulary is at /defects.json and the desk that runs the battery is free at /api/conformance/v1 — point it at your own door, or at ours."},{"step":3,"name":"The signature","what_happens":"The reading is written as one dated observation and signed ed25519. The signature covers the observation, not a summary of it, so an artifact cannot be edited into agreeing with a later story.","what_you_can_check":"Verification is free and permanent at /api/verify/{id}, and it works offline: the public key is published and the artifact carries everything the check needs."},{"step":4,"name":"The chain","what_happens":"Observations are sealed into weekly snapshots linked by hash, so a row cannot be changed after the fact without breaking every snapshot after it.","what_you_can_check":"Every snapshot is listed at /corpus.json with its digest. Fetch two consecutive weeks and verify the link yourself."},{"step":5,"name":"The anchor","what_happens":"Snapshot digests are submitted to OpenTimestamps for Bitcoin anchoring, which puts the existence of a reading at a time beyond this store's reach to revise.","what_you_can_check":"The anchor proofs are public and verifiable with any OpenTimestamps client. We cannot forge them and cannot withdraw them."}],"how_money_works":{"order_of_operations":"The store delivers first and settles after. The work is done, then payment is presented at the last moment before the artifact is signed. A delivery that fails takes no money at all — which is why there is no refund queue to join and nobody to chase.","what_money_buys":"Our labour on the record. Never the record itself: the corpus, the battery, the vocabulary and every published observation are free forever and are not behind any payment. A purchase buys a fresh look, a longer look, a look aimed somewhere specific, or a signed artifact you can hand to a third party.","what_money_never_buys":"A verdict. Nothing on the shelf changes what an observation says, and a paid look that finds a defect reports the defect. If money could move a reading, every reading would be worth nothing.","rails":"USDC over x402, on Base, Polygon or Solana.","recurrence":"Nothing here charges again by itself, ever — there is no mechanism that could.

Every step names something you can check without us: the discovery feeds are public, verification is free and works offline, the snapshots carry digests you can relink, and the anchors are in Bitcoin. If a claim here has no walkable path, that is a defect and the corrections desk wants it."},{"q":"What happens if I pay and the thing fails?","a":"Nothing is taken. The work is produced before payment is presented, so a failed delivery settles nothing. That is a property of the order of operations, not a policy we could quietly change."},{"q":"Will buying something change what you say about my door?","a":"No, and the store is built so it cannot. A paid look that finds a defect reports the defect. The record is free either way, and a purchase never removes, softens, or delays an observation."},{"q":"Is anything here a subscription?","a":"No. Some items cover a term of days for a single payment, and the term simply ends. This store holds no card and no mandate, so there is no mechanism by which a second charge could happen without you deciding to make it."},{"q":"Can I use the record commercially, or to build a competitor?","a":"Yes. It is published free and licensed for reuse. We would rather the market had good evidence in it than that we were the only ones holding any."},{"q":"You observed my door and got it wrong.","a":"Two free paths: the corrections desk, which publishes dated corrections rather than quietly editing, and a standing note, which puts your own dated statement beside our observation on every surface that shows it."}],"security":{"what_this_surface_reads":"Its own shelf, at request time.

That is stated because it flatters us."}
