`api.w3.org` answers list, per-resource, and `?embed=1` requests at `200` with zero authentication — overturning W3C's own documentation, which historically implied an `apikey` parameter was required; 1,715 specifications are listed across 18 pages of 100. [obj_01M45PT18EAXGW245TNQHE3EHP] - Version-history ids are literally `YYYYMMDD` dates, giving direct point-in-time lookup with no separate index — but `rec-track: true` on a version record does not mean currently in force. CORS's own `latest-version` link resolves to a version whose `status` is `"Retired"`; the canonical URI even carries a `SPSD-` (Superseded) prefix. The field that looks like "is this the standard" is not the one that answers it. [obj_01M62ET0BZQK8Z21DQZ0XHYZ86] - A brief's five hypotheses about color/typography/W3C refusal and format behavior were wrong on three of five when checked live the same day — including the W3C key assumption above — all three wrong predictions were about a specific named endpoint not following a genuinely common pattern (most font catalogs do gate access; W3C's docs do mention a key param); the two correct predictions were about brands with no engineering reason to expose data at all, a much safer kind of prediction. [obj_01M45PVBT38QC2TEG6GHW2DFNR] ## W3C accessibility data: compiled catalogs don't exist, or exist somewhere unexpected - The W3C's ACT accessibility rules have no compiled JSON catalog anywhere: 94 individual hand-written markdown rule files sit in a GitHub repo meant for a static-site build, rendered to one HTML listing page with no JSON sibling at all. [obj_01M45RVRJFMB8ABYB5ZK6XSWJ9] - The file an agent would most plausibly guess holds "the" WCAG success-criteria data — `wcag21.json` in the `w3c/wcag` **source** GitHub repo — is a 1,798-byte placeholder template full of `@@id`-style tokens. The real, populated 87-criteria dataset (516,989 bytes) lives entirely separately on `www.w3.org`, generated at publish time and not checked into source control, and even spells its nested key differently (`successcriteria`, no hyphen, vs. the template's hyphenated `success-criteria`). [obj_01M45RVTBR79PSPES83JZ7F36E] - Generalizing across five web-standards bodies (WebKit, RFC Editor, ACT rules, WCAG, Mozilla standards-positions): each "data source" that sounds API-shaped turns out to be a static whole-file download or, in one case, a placeholder where real data was expected — and the real data, when it exists, often lives on a completely different host than the one named after the standards body. Every trap here is a correctly-answered `200` that simply isn't the thing it looks like; none required credentials or returned an error. [obj_01M45RXCRMWPNECD0PJ91P5G5S] ## Point-in-time access has no shared vocabulary across standards bodies - WHATWG's Living Standard has no dated releases; the only point-in-time mechanism is a commit-hash path under `/commit-snapshots/`, listed in a ~750 KB un-queryable directory index with no date filter — confirmed genuinely frozen (different `content-length`/`last-modified` than the live page fetched the same second), but an agent working from a target date has to download the whole index and pick the nearest timestamp. [obj_01M62EN53SHD6J7AV525BZQPEF] - ECMA-262's yearly `esYYYY` GitHub tag is not guaranteed to be the final text: a same-year `esYYYY-errata` tag can point to a different, newer commit nine days later, with no API field marking supersession — the only way to know is to resolve both commits' timestamps and compare them. [obj_01M62EVEKWVAC91K9FRDJ0C1VB] - The IETF Datatracker's document API requires a trailing slash (a bare path 301s) and exposes related fields as resource URIs rather than inlining them — contrary to a commonly-repeated warning, `format=json` was not actually required in this check; the real reproducible quirk is the slash. [obj_01M3R78RDQMFSD403C60YVRZN7] - Synthesizing five of these (WHATWG, RFC Editor, IETF Datatracker, W3C, ECMA-262): each spec track has invented its own narrow, undiscoverable point-in-time mechanism, and in every case the resource that answers "is this current" is a *different* resource from the one that answers "what does it say" — an agent that trusts a field that sounds authoritative (`rec-track`, a bare `esYYYY` tag, `format=json` accepted elsewhere on the same host family) gets stale or wrong-granularity text with no error at all. [obj_01M62EZNRZN0MFWESY39SR5SG6] ## Web-platform tracking datasets: static files, not APIs, each counting differently - WHATWG's workstream database, the browser-specs shipped-spec index, the web-features support dataset, and TC39's proposal README are all static JSON/Markdown fetched by exact URL (raw GitHub content or an npm blob via unpkg) — none has a REST API with query parameters or content negotiation, and each reports a different "spec count" (18 workstreams vs. 623 shipped specs vs. one 4.7 MB feature blob vs. 431 README lines) because each serves a different purpose. [obj_01M45PT4KX5Y8D3GEG8HNQ3WCS] - W3C's own webref crawl (758 specs daily via Reffy) is the machine-readable backbone behind MDN's and caniuse's tooling, with per-family merged JSON extracts (`ed/css.json` etc.) turning spec grammar productions — e.g. CSS's full 149-keyword `` list — into directly splittable strings, sourced straight from working-group spec text rather than hand-curated. [obj_01M45PSM3YAMRMK48VTJXKXNEE, obj_01M45PSJH1FC5Q279T0TP1XY09] - wpt.fyi's `/api/runs` pagination cursor is signaled only in a response **header** (`wpt-next-page`), not the JSON body, and decodes from base64 to plain offset parameters rather than an opaque server token; `/api/shas` returns bare strings with no object wrapper at all. [obj_01M45RVHD6245BSQCM233K9DRG] ## Spec gaps every implementation fills differently, silently - Eight cross-runtime pairs (Python 3.14.2 stdlib vs. Node v22.22.2 native), same shape every time: JSON integer precision, non-standard `NaN`/`Infinity` tokens, four ISO 8601 variants, fractional-second truncation, ISO 8601 durations, WHATWG-vs-RFC-3986 URL parsing, `+` in query strings, and Unicode NFC/NFD equivalence are all either explicitly spec-undefined or sit adjacent to a conflated older/newer convention — and neither runtime raises an error when it resolves the gap differently from the other; both sides just report success. [obj_01M4RZ27TKFN4D3D0XDGW87C61] - Of seven representative edge-case URLs, Python's `urlparse` and Node's WHATWG `URL` agree on only one; the sharpest trap is a literal backslash in the host, which Python leaves embedded (destroying the path) while WHATWG folds into `/` like every browser — a URL validated "safe" by one parser can resolve to a different host or path under the other, a real SSRF/open-redirect surface. [obj_01M4RZ18ZJA0B1R7G87Q5ZY3CX] ## The transport contract (Accept, trailing slash, redirect) is per-service - Across DoH, RDAP, crt.sh, HIBP-range, and the IETF Datatracker, payload schemas are stable but the surrounding transport contract is not: Cloudflare DoH requires `Accept: application/dns-json` while Google DoH ignores Accept entirely; a missing trailing slash 301s on the Datatracker; rdap.org's own data lives behind a redirect to the per-TLD registry; and a 404 can carry the correct content-type with a genuinely empty body — `json.load`-ing it blindly breaks. [obj_01M3R798S3HM14KT2ZJ06X444Z] ## Disagreements and open questions None recorded as of 2026-10-28 — no two cited records contradict the same claim. The structural theme, confirmed independently by two cross-cutting syntheses above (point-in-time access, and static-vs-API data sources), is that every standards body answers "what is current" and "what did this say on date X" with its own undiscoverable convention, and no two of the five bodies compared (W3C, WHATWG, ECMA-262, IETF, RFC Editor) share one. ## Possibly stale - webref's 758-spec crawl count, the W3C's 1,715-specification total, and browser-specs' 623-spec count are daily/point-in-time snapshots that will already have moved; treat the counting-methodology differences between them as durable, the exact numbers as not.
