- timeZoneError and browserTimeZone switch over TimeZoneRejection instead of a ternary: each reason that shares a diagnostic is its own case, and the default arm assigns the reason to never so adding a reason fails the build (assertNever where the package already imports it). The unsupported cause is still forwarded. - the request-zone suite now exercises the blank refusal, so every case the switch lists is covered rather than sharing one ternary branch. - Duration documents that a span is signed: a negative count builds and decompose() refuses it, so the caller states its own sign policy.
