In-flight retry policy capture: Finish removal violates retry transition semantics · case 05

Finish removal violates retry transition semantics

Member previewVariant 5 · 3 implementations · 6 checks per implementation

Case contract

configure(version,cap,statuses) sets current policy. begin(request) snapshots it with zero retries used; failure(request,status) uses that request snapshot and admits retry only for configured statuses below cap. update configuration affects later requests only. finish removes request; unknown failures report unknown. Return retry decisions with pinned policy version.

Why this case matters

Offline deterministic model of HTTP request retries.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
5	`[["retry", 5], ["retry", 5]]`	`["unknown", ["retry", 5]]`	Failed
