The GGUF-crate engines (Gemma and Falcon-H1) reported no `weights_digest` and no `precision`. A receipt from a real model therefore bound it by recipe name alone, and #294's routing gave a grant's `ModelIn` caveat nothing to match. A grant that named the model it permitted refused every real backend. The engine itself recorded the intended fix: address the weights once, at load, over every byte, and report nothing rather than a partial digest. - `mesh_engine::weights_digest(dir, files)` is the shared rule (SPEC §3.6). It is BLAKE3 over the canonical list of the files the forward pass reads. Each file is named by its path relative to the model directory and addressed by the streamed BLAKE3 of all its bytes, in path order. File names are part of the address, and listing order is not. - `GgufEngine` addresses `config.json` plus `model.safetensors`, or the index plus every shard it names. A shard the index names but the directory lacks is an error. It reports `fp32`: the loader widens every tensor to f32. - `FalconEngine` addresses `config.json` plus `model.safetensors`. The tokenizer is not addressed, because it maps text to the ids a caller sends and does not reach the forward pass. It reports `bf16`, the only dtype it binds. - Both report the digest before serving (`ServingEngine::weights_digest`) and the same digest after, which is what mesh-core's model check requires. - SPEC §3.6 states the rule. Checked on the build host: - mesh-rs: 79 tests pass. mesh-engine-gguf's synthetic-directory test runs under the gguf feature, as CI's mesh-rs leg builds it. - On real weights, a sharded 12B Gemma directory (config, index and three shards) addresses exactly the files on disk. It took 8.5 minutes from the host's external disk; at load the loader has just read the same bytes, so they normally come from the page cache. - Every Cargo.lock is current, including joulehook-rs, which locks mesh-engine. Clippy is clean. - Mutations each fail tests: names left out of the manifest, hashing only a file's head, and skipping the index's shards. Co-Authored-By: Claude Opus 5.5 <[email protected]>
