NNUE search integration: FH% tables, NODE_TYPE refinement, TREEDUMP rewrite

2026-10-23T20:19:17Z

- data.c/chess.h: widen the joint FH% table's late axis 16->17, dedicating the new bucket 0 to a whole-node ("will something here fail high at all") sample rather than sharing it with the first-leftover-move curve. Add an NNUE-eval counterpart table (g_uJointFHThousandths_NNUE) and an NNUE counterpart of the beta-side table, selected at runtime based on whether NNUE eval is active. - search.c/searchsup.c: add _RefineNodeTypeGuess, which uses the FH% tables (via g_NodeTypeGuessTable) to refine a node's NODE_TYPE guess instead of the old heuristic; thread uParentMoveFHEstimate through PLY_INFO so a node can see its parent's prediction for the move that led to it. - generate.c: initialize sKillers[2]/[3].uBonus unconditionally (an uninitialized-stack read caught by valgrind under LTO; harmless today but a real bug). - dumptree.c/chess.h/GNUmakefile: replace the long-dead DUMP_TREE XML tree dump (written for a GUI this project no longer has) with TREEDUMP, a flat, path-keyed move/result trace meant to diff against an identically-instrumented Stockfish build -- see docs/TREEDUMP_FORMAT.md. - docs/DEEPER_PRUNING.md: notes on closing the search-efficiency gap vs Stockfish. - crafty_egtb/stockfish_xboard/typhoon_nnue: wrapper scripts so match_play.py's Engine class can drive Crafty, Stockfish (via PolyGlot), and an NNUE-enabled typhoon the same way it drives HCE typhoon. - tests/lop: rename lop.txt -> lop.ep_; update compare_lop.cpp. - annotate_pgns: add aggregate_marginsafety.py, dedup_pgn.py, fit_lazy_probe.py; update annotate.py/run_nnue_pipeline.py for the NNUE training pipeline. - .gitignore: ignore compile_commands.json (clangd build DB) and eval.nnue (a symlink into the untracked head_reference/ comparison baseline), neither of which belongs in the repo.

Track match_play.py's real dependencies (tune_eval_dna.py, filter_pgn.py) and Scott's overnight-SPRT shortcut (test_vs_head.sh); gitignore generated caches/PGN output.

tune_eval_dna.py isn't Texel-tuning-specific tooling anymore -- it's a load-bearing dependency (match_play.py does `from tune_eval_dna import Engine`), so it needs to be tracked for match_play.py to run at all on a fresh checkout, independent of whatever happens to the rest of the auto-tuning pipeline. filter_pgn.py (builds twic_filtered.pgn, the pool match_play.py's --pgn points at) is similarly not tuning-specific. test_vs_head.sh is Scott's shortcut for the overnight SPRT run discussed this session (head_reference/typhoon vs. current build, --games 20000 --workers 20 --st 1 --sprt --elo0 0 --elo1 5). Left untracked, Texel-pipeline-specific and matching this session's move away from auto-tuning: bake_dna.py, dna_diff.py, dna_trend.py, cycle.sh, run_ecm.sh, compare_ecm_*.py, tuned.dna. .gitignore: eval_tune/__pycache__/ and eval_tune/opening_cache/ (pure regeneratable caches) and src/{match_games,self_play_games}.pgn (match_play.py's --pgn-out game logs, generated output not source) -- the dna/first.dna / dna/original_baseline.dna accidental-commit from earlier tonight was exactly this class of mistake, catching the obvious repeat cases now.

Stop tracking pgn data files, ignore pgn/ going forward

2026-08-25T02:08:30Z

These are large generated/downloaded data files (twic.pgn alone is 3.5GB) that don't belong in version control.

Minor

2026-02-20T01:15:16Z

Add ignore files.
