Registry notes

Subscription confirmed through the publisher's own signup flow (sender [address withheld]). Bulletins were observed in the project mailbox before registration; registered 2026-09-26 and ingested from the first poll after deploy — earlier bulletins are not backfilled. Gate-3 coverage evaluation (2026-09-28, from live delivery): 1 bulletin -> 1 item on 2026-09-28 (an announcement of two new audit reports). The bulletin carries no link to a web copy, so the item cites the archived message itself. DKIM-verified with the key archived; signed by service.govdelivery.com, the delivery platform's domain, not the agency's. The inbox rule labels and ingests such mail; the same message delivered to the junk folder would be refused (GUIDE §3, 2026-09-26). One bulletin is a thin sample, and the topic selection made at signup was not recorded, so this evaluation claims no coverage relationship to the agency's full output: the bulletin stream is the subscription's own measure of coverage, observed continuously by the collector and shown on the source page. Related entries that can publish the same news: oversight-gov, treasury-email, treasury-newsroom. A copy at the same URL merges as corroboration (GUIDE §3); the same event published at a different URL is listed separately, by rule.

How we ingest it

Channel

email bulletin

Method

Subscription bulletins to the project mailbox, ingested by the email adapter (src/fapd/email_sources.py; raw RFC-5322 capture, DKIM verify-and-archive).

Adapter

govdelivery

Poll cadence

the project mailbox is read about every 15 minutes

Requests

none — bulletins are delivered to the project mailbox by the agency's own subscription service

Authenticity

every message's DKIM signature is checked on arrival and the result is disclosed on each item; in the inbox a failing signature is labeled, never silently dropped; in the junk folder, which is read too, only a message whose signature verifies and matches the sender's domain is accepted, and the rest are refused and counted

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, delivered by email.

This label has held since 2026-09-28T15:30:51Z (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.
