Topaz v0.2.4 20a FORMAT-2 checkpoint

This is a Scitomo FORMAT-2 conversion of the official Topaz v0.2.4 pretrained 3-D 20a denoiser.

Upstream source: tbepler/topaz, revision c6dde54398875dcc6a210f83de019c9165fb474c, tree 25396d246daab8de75fb1adce57f7ad5cc883bf4.

The authoritative PyPI source distribution SHA-256 is e59200127fda2c23f5357c86e2c5f3e4ddfd5c103cf0b7138e700cac5b1fc516. The matching vendor checkpoint SHA-256 is aa1df1163417f78ad88aa59f7b86856b2f43be7ae910b188de3fa4f9f9ec1ab2.

The package has 34 canonical tensors / 2,916,337 parameters. Dense native parity was bitwise exact before export and after ordinary generic FORMAT-2 reload in the frozen conversion environment.

Whole-volume population z-score and output mean/std restoration are Topaz inference-profile semantics. Exact local valid-core support is 160 samples each side with modulo-32 core/origin/evaluation requirements, while the dense Network itself requires only spatial axes >=32 and no modulo-32 divisibility.

The historical vendor tiled patch_size=96, padding=48 path is distinct evidence and is not exact execution of the dense operator.

The upstream Topaz GPLv3 license text is retained at resources/TOPAZ_LICENSE.txt.

Redistribution of the bundled v0.2.4 checkpoint is approved under that upstream GPLv3 package license. This FORMAT-2 package revision 2 supersedes the initial immutable publication 75277be1d638bd499c3f597acd710d8105958b70, whose manifest conservatively recorded redistribution as unknown. The learned weights, Network construction, inference profile, and scientific validation are unchanged.

No retraining or new scientific-quality claim is made by this conversion.
