Retry advice across wall and monotonic clocks: Response reset violates retry transition semantics · case 04
Response reset violates retry transition semantics
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
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| 5 | ["ambiguous", "ambiguous"] | ["ambiguous", "missing"] | Failed |
