FA-18295 / Time representation / Member archive

Atomic offset step applies one tick late or before its effective instant · case 05

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

Case contract

A stipulated offset table has initial atomic-minus-civil offset and a single step effective at atomic transition T. Translate atomic to civil label using active offset, retaining a fold tag for repeated labels on positive steps. Report label, offset, previous-label delta, discontinuity direction, repeated-label window membership and invertible pair. Offsets need not correspond to any real-world table.

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 2	`[90, 10, 1, true, false, 1, 100, [90, 1]]`	`[89, 11, 0, true, false, 1, 100, [89, 1]]`	Failed
