Methods

METHOD match(String input) RETURNS boolean

METHOD replace(String input, String replacement) RETURNS String

METHOD captureGroup(String input, int32 groupIndex) RETURNS | String

Capture group groupIndex of the first match in input (group 0 is the whole match). Pipe-XOR: SUCCESS yields the captured substring; FAILURE when the pattern does not match or the group index is out of range.

The native returns nullptr on no-match / bad-index, which now marshals to the PRESENT empty string (a String is never EMPTY — I.D.vii.b, so the old IS VALID test is E6068). Absent a companion presence FFI (as System.getenv uses ev_env_has), no-match is read as an empty result. KNOWN LIMITATION: a group that legitimately matches the empty string is therefore reported as FAILURE — acceptable for the current surface; distinguishing the two would need an ev_regex_* presence native (module rule: needs sign-off).
