AKUNUR 3.1.0-alpha.8 UI TEST CHECKLIST

[ ] Header and feedback panel show v3.1.0-alpha.8.
[ ] Printable PDF opens. (It remains the older alpha.11 reference; use the in-app Rules for current 3.1 reserve/three-player changes.)
[ ] No corner action is offered before that player earns the Still Point marker.
[ ] The first two token claims by each player require an Echo Piece placement.
[ ] A third or later token claim does not request an Echo Piece placement.
[ ] Reaching the selected corner threshold shows Alignment but does not end the game.
[ ] Losing a corner clears the relevant Alignment status.
[ ] An aligned supported stone can move directly onto the Still Point.
[ ] The final move has no exit-selection step and the winning stone remains at centre.
[ ] Copy game log works on desktop and mobile and preserves one entry per line.
[ ] White, Black and Wood Echo Pieces remain owner-coloured and carry a clearly visible small red state marker.
[ ] Game summary labels show Corner claims and Corner takeovers.
[ ] Undo restores marker, Alignment, bonus placement and terminal state correctly.
[ ] 4-corner extended setting applies after reset and still requires a final Still Point claim.


ALPHA.4 MOBILE / PERSISTENCE CHECKS
[ ] On a phone-sized viewport, the reserve action is immediately below the board and above the log.
[ ] The lower Controls-panel reserve button is hidden on phone/tablet layouts.
[ ] The mobile action names the active player and shows that player's reserve count.
[ ] White, Black and Wood Echo Pieces remain predominantly owner-coloured with a small red state marker.
[ ] A corner capture increases the captured player's reserve rather than permanently removing the piece.
