FA-18814 / Time representation / Member archive

Clock-table coverage assigns effective interval boundaries incorrectly · case 04

The decoded time state disagrees with the explicit regression oracle for covered.

Case contract

A timescale offset certificate declares coverage [start,end), publication instant, expiry instant, version and source identity. A query may use offset only inside coverage with a currently valid certificate and minimum accepted version. Query time and validation wall time are independent. Return status precedence identity/version/publication/expiry/coverage, admitted shifted coordinate, remaining validity and coverage margin.

Why this case matters

Clock transfer and timestamp consumers require preserved coordinate, phase, validity and elapsed-time semantics.

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
fixture 9	`["ok", 207, 5, [100, 0]]`	`["uncovered", null, 5, null]`	Failed
