FA-29507 / HTTP retries / Member archive

Nested client retry ownership: Retry admission spends beyond the owning scope cap · case 02

Retry admission spends beyond the owning scope cap

Member previewVariant 2 · 3 implementations · 7 checks per implementation

Case contract

enter(layer, allowance) pushes a retry scope. A child with any ancestor delegates retry to the oldest scope and never spends its local cap. fail returns retry/exhausted charged to oldest scope. leave pops the current scope; success clears every scope. Return decision pairs and remaining scope budgets.

Why this case matters

Offline deterministic model of HTTP request retries.

Sample boundary fixture

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