18.1.0

Adjudication API

Adds a public adjudication API for the two external game-ending events - flag-fall and resignation - that applies the FIDE "opponent cannot win" draw exception for you, and changes the fifty-move report to count in moves by each player rather than halfmoves. The release is additive: no public type changes shape.

Notable

• New io.github.dlbbld.ashlarchess.adjudication package. Adjudicator adjudicates a flag-fall (FIDE 6.9) or resignation (FIDE 5.1.2): the event is a loss unless the would-be winner cannot checkmate by any series of legal moves, in which case it is a draw. Each event has a quick variant (rules DRAW / LOSS from the fast analyzer - bounded latency, for live play) and a full variant (adds UNDETERMINED from the complete analyzer, for game-end and offline use). Verdicts are the new AdjudicationResult enum (DRAW, LOSS, UNDETERMINED).
• The README is now generated from README.template.md plus executed example source: every shown snippet provably compiles and every shown output is captured from running it, and a drift test fails the build if the committed README does not match a fresh render.

Behavioral

• The fifty-move report (Reporter) now expresses every no-progress run's counts as moves by each player, written (White/Black), instead of a single halfmove count - matching the FIDE "moves by each player" wording (claimable at 50/50, automatic draw at 75/75). Consumers that snapshot or parse the printed report text will see the new format.

Internal

• Compiler-warning cleanup: reduced the visibility of package-internal helpers (including two InsufficientMaterialUtility bishop predicates) and supplied an explicit charset to IoUtility's stream-to-string conversion.
