Four instruments recorded silence as success, so a void run scored as a clean
one:
- readTerminalImeBoundaryTrace returned an empty trace when the probe never
installed, making every "nothing leaked" negative pass vacuously
- summarizeLatencies([]) returned a perfect zero distribution that passed all
three latency thresholds
- the macOS Vietnamese spec pinned an input-source ID that does not exist, and
failed as though the operator had chosen the wrong source
- the expectedLineCount=1 prefix property was undocumented and one edit from
silently downgrading a PTY assertion
Input sources now resolve by enumeration and name the near-matches on failure.
