Phase A NNUE: feature-indexing spec, annotation/training pipeline, dump nnuefeatures

2026-10-15T20:11:22Z

Builds out the NNUE Phase A prototype per docs/NNUE.md: - src/nnuefeatures.c: standalone HalfKAv2_hm feature-index reference implementation (new `dump nnuefeatures` command), sourced from Stockfish's half_ka_v2_hm.{h,cpp} (sf_16 tag), including the 0x88->64 square conversion typhoon's own board representation needs. - annotate_pgns/: sharded TWIC/self-play annotation harness (annotate.py), position extraction, quiet-position filtering (flat and game-shaped, plus an upstream --prefilter-quiet option), train/holdout game-level stratified split, WDL-sigmoid K fitting, the Python HalfKAv2_hm reference encoder (nnue_feature_spec.py) and its bit-for-bit cross-checker against the C side (cross_check_features.py), and a first PyTorch training pipeline (nnue_model.py, nnue_train.py, build_training_tensors.py) -- a 256x2-32-32-1-ish net trained locally on CPU against ~1.85M quiet TWIC positions as a pipeline/framework validation pass. - Finish an in-progress InitMagic/InitLMRTable/InitEval -> InitializeBitboardMagic/InitializeLMRTable/InitializeEval rename: chess.h's prototypes hadn't been updated to match the already-renamed definitions/call sites, leaving 4 implicit-function-declaration warnings. - tests/arasan.epd: new curated EPD suite. - docs/: add the project's design docs (previously untracked).

Delete these, I have a newer one.

Add search self-tests (hash consistency, QSearch sanity) and a native EPD parser (`epd` command + ParseEpdRecord), fixing a silent-corruption bug in convert_epd.pl that broke every Black-to-move EPD conversion.

testsearch.c: TestSearchHashConsistency exercises the hash table through real search (repeat-with-warm-table and shallow-then-deep agreement) rather than synthetic store/probe calls. TestQSearchSanity checks termination and a node-count ceiling; its own header documents that the TEST=1 self-test build doesn't define PERF_COUNTERS, so it checks whole-search node count rather than the qsearch-only counter. A planned null-move zugzwang test was dropped in favor of tests/zugzwang.epd (best-move outcome, not an internal counter) after the three classic literature positions turned out not to structurally reach this engine's verification-search code path on this build. fen.c/script.c/command.c: new `epd ` command reads raw EPD directly via ParseEpdRecord, reusing ScriptCommand's existing suite-reporting machinery (factored into _ProcessSuiteLine/_PrintSuiteReport). Replaces the need for tests/convert_epd.pl, which had a real bug: its bm/am regex's [^b]+ filler breaks on any Black-to-move record (side-to-move field is literally "b"), and unscoped $fen/$id/$solution globals meant a failed match silently duplicated the previous record instead of erroring. tests/ep_to_epd.pl converts the existing setboard/solution/avoid/id/go suites back to real EPD; cross-checked ecm_ringers.ep_ via `script` against ecm_ringers.epd via `epd` -- byte-identical node counts and solve stats. Added .epd siblings for every genuine tactical suite in tests/. Added src/TESTING_PLAN.md: full audit of test*.c coverage gaps (dead SEE oracle, unwired eval/recognizer tests, zero hash-table correctness coverage, thin search self-tests) with a prioritized plan for closing them.
