docs(devx): the floor probe can read this file now

The docblock above `SELF_TEST_VERDICT` told readers the mechanical probe in
`scripts/measure-self-test-floor.mjs` cannot read this file. Since the anchor
repair it can: the injection lands on the definition below and the copy parses
and runs. What remains is a different, named limit — the probe's own copy under
`scripts/`, which this gate's single-site sweep reads as a second carrier
(#15515).

Comment only; the line count is unchanged, so nothing below it moves.
