AKUNUR 3.0.0-alpha.8 AUTOPLAY / AGENT CHECKLIST

[ ] Strategic is shown as the initial AI agent.
[ ] Change AI agent cycles Strategic -> Tactical v1 -> Legacy heuristic -> Random -> Strategic.
[ ] Strategic autoplay remains responsive and the Stop button works.
[ ] Strategic target/progress diagnostics identify a corner plan.
[ ] After a player claims a first corner, Strategic can build a supported route to the Still Point.
[ ] A Still Point passage resolves as one compound action: origin -> S -> empty non-corner destination.
[ ] No stone remains on the Still Point between decisions.
[ ] Completing a player's first Still Point passage earns and displays that player's permanent marker.
[ ] Before earning the marker, the agent cannot claim or capture a second corner adjacent to one it controls.
[ ] A non-adjacent second corner remains legal before qualification.
[ ] After earning the marker, an adjacent second-corner claim or capture becomes legal.
[ ] A genuine three-corner win ends normally and does not request a final Echo placement.
[ ] Exact repetition or a strategic plateau stops autoplay rather than running indefinitely.
[ ] Reversible Echo captures alone do not indefinitely postpone the strategic-plateau stop.
[ ] Reversible non-capturing Echo shuttles do not indefinitely postpone the strategic-plateau stop.
[ ] The warning and newest log entry state why autoplay stopped.
[ ] The board remains playable after an analytical autoplay stop; the game itself is not falsely declared won.
[ ] Restarting autoplay creates a fresh analysis window.
[ ] Tactical, Legacy and Random autoplay still run.
