Retry advice across wall and monotonic clocks: Advice retain violates retry transition semantics · case 05

Advice retain violates retry transition semantics

Member previewVariant 5 · 3 implementations · 8 checks per implementation

Case contract

Controlled decoded Retry-After model. response(server Date or None,Age,received monotonic,local wall at receive) resets advice. delta(nonnegative seconds) or date(absolute seconds) records one advice; multiple advice values are rejected. For date, estimate server time as Date+Age, or local wall if Date absent. Project remaining server delay onto receive monotonic clock. advance moves monotonic time forward. schedule returns remaining wait or missing/ambiguous; no network requests or full header parsing.

Why this case matters

Offline deterministic model of HTTP request retries.

One recorded failure
