Follow-up on review feedback. The previous commit consolidated four of the six Live benchmark parsers and left these two on their own hand-rolled `arg()`, which was the inconsistency the first pass was meant to remove. - benchmark-live-control.mjs and benchmark-live-init.mjs parsed --iterations with Number(), so a non-numeric value became NaN and `index < NaN` ran the benchmark zero times before failing on the metrics file. They also accepted only the space-separated form, so --iterations=20 silently measured the default. Both now use parseArgs + positiveIntFlag, which throws on a value that was clearly meant as a number. - benchmark-live-control.mjs read the metrics file with no handling for the case where the run produced nothing: a missing file surfaced as a raw ENOENT stack and a malformed line as a bare SyntaxError. Report both with a diagnostic naming the file and the env var that populates it. - summarize() now reports a `samples` count and nulls instead of letting percentile() read past an empty array, where the NaN serialized to null and a report of nothing measured looked like a real measurement. Prepared with AI assistance under maintainer direction. Co-Authored-By: Claude <noreply@anthropic.com>
