Citation health
An externalcheck on the catalog’s “citable” claim: every published instrument’s primary-source URL, re-resolved. The other citation pins assert the citation strings are well-formed; this asks whether the source still resolves — catching link-rot, the decay threat to a citable resource.
Snapshot probed 2026-06-30. Published instrument primary sources (sourceUrl). Excludes the literature full-text corpus. Machine-readable: /wiki/citation-health.json.

Of 45 primary sources, 38 are live, 0 redirected, and 5 are reachable but bot-blocked (403/429 — many government legislature sites block non-interactive fetches; not a defect). 1 is dead (404) — confirmed link-rot, flagged below for re-citation. 1 did not respond to the automated probe — which can mean link-rot or a host that geo/bot-blocks non-interactive requests; see the note(s) below and re-verify manually before treating as broken.
