Primes¶
- Setup–Resolution Pair
- Programs that work externalize the bearer rather than trusting memory: a machine-readable sunset header on every response, a warning logged on each call, a dashboard of remaining callers, and a removal announcement that quotes the original notice so the two elements are visibly linked at the moment of closure.

RFC 8594 defines the machine-readable Sunset response header, which covers one of the four listed practices.
“This specification defines the Sunset HTTP response header field, which indicates that a URI is likely to become unresponsive at a specified point in the future.”

Mechanisms¶
- API Reuse Boundary Header
- On every response the API returns `Deprecation: true` and a `Sunset` header giving the retirement date (a real, standardized HTTP header),
- Adopting a standardized field — the `Sunset` HTTP header rather than a bespoke JSON blob — lets generic tooling read it without custom code.
This sourceDefines and registers the standardized, machine-readable Sunset HTTP response header for communicating a resource retirement date.
- Deprecation and Forwarding Notice
- Its failure modes are the two halves left undone — deprecating without a live forwarding target (a dead end that just breaks things) or without enforcement (a notice everyone ignores while they keep using `v1` forever).
This sourceDefines a Sunset signal for the date after which a URI is expected to become unresponsive, exposing a dead-end risk for clients that do not migrate.

- Deprecation Notice Feed
- … against it is to target and rate-limit notices, prefer in-band channels the consumer can't route around, and measure acknowledgement — did dependents actually act — rather than mere emission. The `Sunset` header exists precisely to make end-of-life a signal machines can act on, not a paragraph humans overlook.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 5 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Was it audited? Yes. A second, independent pass read the citation against the article text and recorded a verdict.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
