01 / THE QUESTION

Source passage

The project goal is now frozen: determine the game-theoretic value of the normal chess initial position and emit a machine-verifiable strategy certificate.

02 / WHAT THE RECORD SAYS

Source passage

Exact strong-bisimulation refinement was computed on KRK and KQK. It preserves every certified WDL/DTM value, but compresses very little beyond the eight board symmetries.

03 / LIMITS & OPEN POINTS

Source passage

Using the completed tables as an oracle, C2 measured the maximum pruning opportunity. These measurements do not constitute a pre-solution classifier.

04 / THE NEXT QUESTION

Source passage

The missing variable is narrower than before: a cheap relational signature and refinement rule that produces strong enough $D^-/D^+$ bounds to certify most move deletions before the underlying states are solved.

05 / CHECKS IN THE RECORD

Source passage

C1's state/transition/canonicalization/fixed-point pipeline was independently reimplemented for White king and queen versus Black king on the standard board. The declared abstraction treats checkmate as a win and stalemate, queen capture, or infinite non-mating play as a draw; history-dependent FIDE draws are outside this small material universe.
