feat(phase5): full model assembly + e2e parity
...
Wire GreenFormer (backbone + decoders + refiner), add image I/O,
inference pipeline, CLI entry point, and 3 test files (23 new tests).
E2e parity vs PyTorch: max abs err < 1.5e-4 across all outputs.

feat(phase3): PyTorch→MLX weight converter ( #1 )
...
* feat(phase3): PyTorch→MLX weight converter + safetensors output
365 keys mapped (367 source - 2 num_batches_tracked skipped).
Conv weights transposed (O,I,H,W→O,H,W,I), refiner stem remapped,
4ch patch embed preserved. 12 conversion tests + diagnostic report.

* fix(phase3): conv allowlist, unused var, test fixture
- Replace _is_conv_weight heuristic with explicit CONV_WEIGHT_KEYS frozenset (15 keys)
- Remove unused `skipped` list from convert_state_dict
- Module-scoped pytest fixture eliminates 11 redundant checkpoint loads

feat(phase2): MLX decoder + refiner with parity tests
...
- MLP, DecoderHead (SegFormer-style), RefinerBlock, CNNRefinerModule
- All NHWC native, GroupNorm with pytorch_compatible=True
- Layout utils: NCHW<->NHWC, conv weight transpose (OIHW->OHWI)
- Dump script extended to export decoder/refiner weights
- Parity: decoder max_abs ~5e-6, refiner max_abs ~1e-5

feat(phase1): PyTorch reference harness + fixture tests
...
Dump script loads CorridorKey checkpoint, runs deterministic forward
pass (seed=42, 512x512), saves 14 intermediate tensors to golden.npz.
Includes pos_embed bicubic interpolation for resolution mismatch.
32 shape/dtype/range validation tests all passing.
