AKUNUR 3.0.0-alpha.1 VALIDATION REPORT

Completed automated checks
- JavaScript syntax check passed for every .js file in both 2.10.5 and 3.0.0-alpha.1.
- Core smoke test passed under Node: 169 cells, 24 opening pieces and 26 initial legal moves.
- Browser-module linkage test passed: Core.Board, Core.Rules and LegacyHeuristicAgent bind correctly through browser-bindings.js.
- The preserved legacy heuristic selected an action contained in the authoritative legal-action set.
- Behavioural parity test compared 250 consecutive decisions between 2.10.5 and the extracted v3 core. Legal actions, action results and gameplay state matched throughout (excluding version strings, logs and history snapshots containing those strings).
- A 10-game Random-v-Random headless batch completed without engine stalls; all games reached the existing 400-move limit. This confirms runner operation but is not evidence of game balance or quality.

Still required before promotion
- Manual browser regression using web/UI_TEST_CHECKLIST.txt and the board-design checklist.
- Representative replay comparison, especially Echo Piece corner capture and bonus-placement sequences.
- Larger agent tournaments and stronger search agents.
- Physical-board human playability testing.

Status
- Suitable as an architectural alpha and starting point for further v3 work.
- Not a public release candidate.
