TR-CORE-GIN-INTERVAL / GIN interval arithmetic
IF
Temporal endpoints are submitted for arithmetic or comparison.
HOW
Validate interval shape, integer bounds and clock identity; compute only admitted interval operations and
preserve outward bounds.
THEN
Known zero duration stays known; unknown or incomparable values do not become a numeric latency saving.
CURRENT EVIDENCE
Fresh related language/paper/water checks are in the evidence ledger. The test count is suite evidence, not
proof of every branch in this requirement.
REMAINING REQUIREMENT
Use the source and recorded case evidence to close remaining per-branch, native-host and full-contract coverage gaps.
