AKUNUR 3.0.0-alpha.4 VALIDATION REPORT

Automated checks completed:
- All JavaScript files pass Node syntax checking.
- Core smoke test passes.
- Full-history and lightweight execution remain equivalent over 150 deterministic decisions.
- Search previews do not mutate source state.
- Undo restoration passes.
- Decisive-corner and non-winning Echo-placement regressions pass.
- Canonical keys distinguish token availability and pending Echo placement.
- Threefold and no-progress tracker regressions pass.
- Browser-style core, analysis and legacy-agent bindings pass.

Representative headless validation:
- random vs legacy reached a genuine three-corner win in 104 decisions.
- legacy vs legacy ended as analysis-no-progress after 154 decisions, with 2 corners each and a compact replay written.
- Result accounting was valid and no consistency issues were reported.

Manual checks still required:
- Load web/index.html through a static server.
- Confirm board appearance and interactions match alpha.3/2.10.5.
- Start autoplay and confirm a cycling game stops visibly after the configured no-progress interval.
- Exercise corner claim, Echo placement, Echo Point use, capture and undo.
