Registry notes

Probed 2026-07-26: index reachable (HTTP 200), no RSS/Atom feed found or autodiscovered — HTML index diffing required. Probed 2026-07-31 (from the operator machine, outside the server's daily budget): reachable, HTTP 200, robots allows, but no machine-readable feed is advertised — ingestion waits on an html-index adapter, not on the publisher. Phase 5, 2026-07-31: the html-index adapter now exists and was run against this source's captured index bytes. Against the 2026-07-31 capture it reads listing has 19 article link(s); 1 dated inside the 7-day lookback, 6 dated outside it, 12 skipped for no readable date, and the entries it lists carry the publisher's own dates. Activation awaits the operator's polling-cadence decision (the agency class holds 500 requests a day). Probed 2026-08-06: https://www.cdc.gov/rss is an HTML feed-directory page, not a feed (verdict html-only). Same shape as nsf-news. Probed live 2026-09-28 from the operator machine as a brief test, outside the server's budget (identified client, robots allows). ACTIVATED 2026-09-28 with the html-index adapter. Gate 3: 1 entry dated inside the 7-day lookback (2026-09-22), a CDC media release; a low-rate source. Under-coverage: the listing's first page only, so more new entries between two hourly polls than the page holds would not be seen; entries the parser cannot date are dropped, never observation-dated.

How we ingest it

Channel

HTML index

Method

html-index adapter via AgencyClient — one listing fetch per poll, no article fetches (mode feed-only).

Adapter

html-index

Poll cadence

about every 60 minutes while the collector runs

Request budget

the agency class: at most 3,000 requests per day shared across every agency web source, counted from the fetch log (failed requests count too)

Politeness

robots.txt is honored as observed — including each host's crawl-delay, exactly — and every request identifies itself as fapd/0.1 (Free Agentic Publication Digester; +https://fapd.info/bot.html; contact: hustleyourcity@gmail.com); a refusal is recorded, never evaded

Capture and hash

captured raw content is hashed (SHA-256) into the day's committed provenance manifest, hash-chained day to day (PROVENANCE.md)

Ingestion health

●Ingestion health: delivering 1 item(s) in the last 14 days; most recent 2026-09-28; 0 of 18 request(s) to www.cdc.gov returned no content.

This label has held since 2026-09-28T18:49:43Z (UTC) and was last re-checked 2026-09-29T09:47:01Z (UTC).

Counts are of our own requests, retries included. A 4xx or 5xx is the server declining to return content — that may be load, maintenance, on-demand generation, or a limit the publisher sets, and we cannot tell which from outside. Nothing here is a measurement of the publisher.

Ingestion statistics

These figures describe this project's ingestion of this source — items we recorded and requests we made — and nothing else. They are not a measurement of the publisher.
