Two scanner test nits from review 3: meter_test.go:196 pins the separator-run cap with a true account position (C:\Users followed by 65 backslashes), which passes with or without the cap, so the over-report direction for a rootless run is not itself pinned; and the meter fixtures scale with maxSeparatorRun, so inflating the constant to probe the no-cap case allocates gigabyte strings (remove the loop bound instead).

Grounds

• pursued: removing the separator-run bound from endsWithPathFold now fails TestBoundedContextHelpersKeepTheFinding; that mutation passing, or a fixture again derived from maxSeparatorRun, would show it wrong
