Never a ranking. ## Title Feeds ## Summary Four Atom feeds, each derived when it is fetched from the same record the page it mirrors reads: the week's doors, the corpus chain, the corrections and the disagreements — and one per host, at /feeds/host/{host}.xml, that moves only when that door's record does. Every entry links the page it came from, so a reader who arrives through a feed lands on the derivation and the denominator. Nothing here is a ranking, and no feed carries anything the pages do not. ## Feeds ### The Week's Doors #### Path /feeds/brief.xml #### What One entry per signed week: doors named, probed, payable and not, defects by name, the gaps counted against the observer. Each entry links the week's stable page. #### Cadence weekly, after the Sunday round #### Representativequeries - subscribe to weekly x402 endpoint census summaries - follow weekly counts of x402 doors probed and payment challenges observed #### URL ### The corpus chain #### Path /feeds/corpus.xml #### What One entry per signed snapshot appended to the corpus, with its sequence, week and digest. Each entry links the snapshot's JSON, the bytes a signature covers. #### Cadence weekly, after the Sunday round #### Representativequeries - subscribe to new signed x402 corpus snapshots - follow additions to the x402 observation chain with snapshot digests #### URL ### Corrections #### Path /feeds/corrections.xml #### What One entry per correction this store has published against itself: what was wrong, how long, who found it, what changed. #### Cadence when we get something wrong #### Representativequeries - subscribe to corrections SCVD publishes about its own work - get an Atom update when SCVD fixes a reported mistake #### URL ### Disagreements #### Path /feeds/disagreements.xml #### What One entry per divergence between this store's reading and another instrument's, with its state; both readings live on the page the entry links. #### Cadence from a named trigger, never on a timer #### Representativequeries - follow disagreements between SCVD and other verification instruments - subscribe to published differences between x402 endpoint observations #### URL ## Per host ### Path /feeds/host/{host}.xml ### Name One host's changes ### What One entry per change in what the signed chain recorded about one host: the first probe, every verdict change, every change in the set of addresses the door asks to be paid at (as digests). Each entry links the host's history page, where every round we missed carries its reason. ### Cadence weekly at most, after the Sunday round; silent while nothing changed ### Representativequeries - subscribe to changes in one x402 endpoint's readiness verdict - be notified when an x402 door I depend on changes its receiving address ### URL template ## Corrections Things this store said that later proved wrong live at /corrections — dated, with what changed so each cannot recur quietly. If a claim on this surface was ever corrected, that is where the correction stands.
