Failed response disposal and pool eligibility: Poison first violates retry transition semantics · case 05

Poison first violates retry transition semantics

Member previewVariant 5 · 3 implementations · 8 checks per implementation

Case contract

headers(length) opens failed response with remaining bytes; read(count) drains bounded content. eof confirms framing only if no bytes remain, otherwise poisons connection. close marks response closed; release returns pooled only for closed, fully drained, EOF-confirmed unpoisoned response. abort permanently poisons current connection. new resets all connection state. Return drain amounts and release disposition.

Why this case matters

Offline deterministic model of HTTP request retries.
