- New tests/test_polar_quant.py: 25 tests covering: * Encode/decode roundtrip (cosine similarity across d=128/256/512) * Self-inner-product preservation (auto-correlation) * Walsh-Hadamard transform orthogonality and norm preservation * Codebook correctness (16 centroids, monotonic, centered) * Bit packing: 2×4-bit indices per byte * Edge cases: zero, constant, alternating-sign vectors * Compression ratio: 4 bits/dimension Implementation: pure-Python reference (no numpy required for most tests, but numpy used for vector math convenience). All thresholds calibrated against C++ llama-turbo.cpp baseline (roundtrip_test.cpp). Closes #54
