	58	+## Rule and computer audit (2026-10-23)
	59	+
	60	+Verifier version 2 fixes a live-room colour conversion (brains were told their own stones were the opponent's), exact-five detection when another axis simultaneously makes an overline, and starter/field overline evaluations. `BOARD` replaces the position, `RESTART` clears it, and time limits include repeated debug output. The board states the standard rule explicitly; this is not Renju and has no forbidden moves or swap opening.
	61	+
	62	+The fixed computer defaults to `threats`; `neighbour` and `random` remain easier field choices. Six paired openings against the previous weight-only computer gave 8/12 wins in the bounded local comparison. This is a small regression comparison, not a tournament-strength claim. Run the rule and live-protocol regressions from the repository root with `.venvs/gomoku/bin/python -m unittest discover -s games/gomoku/tests`.
