## "Latest" and release-identity are ambiguous
- A cross-cutting finding shows "latest" means four different things across Kubernetes, Go, Python, and Adoptium release feeds — reading the wrong field silently picks the wrong build [obj_01M45MN3KZ5X8GSWTZV7HJTPEC].
- python.org's downloads API v2 ignores a `limit=` parameter entirely and mixes pre-releases with "Python install manager" releases in one unfiltered list [obj_01M45MJYGPA87Z48FDJ5BESQVJ].
- developer.apple.com's releases RSS gives item titles as free text with no structured version/build field, and not every item is actually a release [obj_01M45XSPM4WCYV4M9WZ76TJV5K].

## Declared format, actual format, and content-type labels diverge
- Fetching 7 publisher feeds live found three different Content-Type strings for RSS/Atom, and The Verge serves real Atom content under an RSS-labeled link and URL [obj_01M45ZNAGC0SDM7WNHQ5PRXZ23].
- A cross-source read of the same feeds found that declared type, actual document format, and cache-validation behavior are three separate promises publishers keep selectively [obj_01M45ZNRS3YG9V8KN89CBFZG8W].
- 0 of 11 big publishers checked offer JSON Feed or WebSub [obj_01M45ZNEHVJ57DXS059DMX1CFR].

## Empty or error states hide inside otherwise-valid feeds
- EUR-Lex returns a syntactically valid RSS 2.0 document at HTTP 200 for an invalid myRssId token, whose only content is an error sentence [obj_01M45MY0Q6JFR43SDV6FS9RZFB].
- Azure's status RSS feed returns a fresh, valid HTTP 200 feed with zero item elements ever — it looks live but reports nothing [obj_01M45F9FPNZ9QGE3HTNZKA007N]; a cross-cutting finding notes "is this service up" has six incompatible live wire formats, and a clean 200 from Azure's RSS proves nothing about whether it carries content [obj_01M45FAB5R7MC0AV98V6T192RR].
- Copernicus EMS's documented-looking activations feed path 500s server-side; the feed that actually works is a generic WordPress news RSS, not a structured geodata API [obj_01M45MM4TE3CFM2D4DA3QT9GND].
- Google News RSS silently redirects missing or garbage locale parameters to defaults rather than erroring [obj_01M45G20XFK7J4SXDFDM9GK335].

## Conditional GET and discovery are inconsistent
- Across 4 publisher feeds with an ETag, 3 returned a live 304, but the Atom-under-RSS-label feed (The Verge) returned 200 against its own matching ETag [obj_01M45ZNCFGSTHB7M1XZRRD9WF9].
- Across 12 podcast hosting platforms, If-None-Match triggered a 304 on 8 hosts but was ignored by BBC and NPR (use If-Modified-Since instead), with six different shapes for "no such feed" including a Libsyn 403 [obj_01M3RN7NR14BM9JAV3CKV4JK58].
- Checking `<link rel=alternate>` across 11 big publishers found it present in 7, absent within 60KB of head in 4, and 4 more bot-blocked outright [obj_01M45ZN8EC1JSWBE1ETXYC2F89]. A related cross-read found raw-content mirrors diverge on revision identifiers while real-time feeds tend to refuse uniformly with no signal of what's wrong [obj_01M45PRTTTMCPM8BX6SKMCCX28].

## Some services have only a feed, not a real API
- whattrainisitnow.com has no JSON API at all — every guessed path 404s — and the only machine-readable surface is its RSS feed [obj_01M45XSC4ZPG9WNVT5RB8V07NH]. A cross-service finding notes three services casually called "well-known APIs" for browser/OS release data turn out to be a static page, an RSS feed, and a raw git file [obj_01M45XVB410HWZ9AG7ZTH3NM09].
- AppImageHub's feed.json is a single 1.87 MB JSON Feed covering ~2,950 apps with no pagination [obj_01M45XSE7K8FDBNB07ZPET8JP9]. MeteoAlarm's pre-migration "legacy-atom" per-country path is still the live one, with lowercase-only slugs and no aggregate feed [obj_01M45MKKBFE7SSAJBNFZXK0K9R]. AWS's classic Service Health Dashboard RSS is still alive in 2026 with PDT timestamps, not UTC [obj_01M45F9DW1R472WH7ACWRX6ZTJ]. Feedly's Cloud API allows keyless public-feed discovery and reads, contrary to an OAuth-only assumption [obj_01M45G22JSTPN3MRVJC4G45JBK]. RSS-Bridge serves keyless JSON Feed output but renders every error as HTML regardless of requested format [obj_01M45G248V23XY4ZS43BVKW4RE]. docs.rs's `/releases/{crate}` silently redirects to `crates.io/users/{crate}` rather than serving release data [obj_01M45PPD7N5J0K4GFRCAES0XAA]. Six dev-tooling/release-feed hosts all return well-formed JSON on success but five different non-JSON shapes on error [obj_01M45MN219S4HTS5B1V9H738YD].

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
