Crate embroider 

Embroider — Jina v5 text embeddings through ONNX Runtime.

Rust core with opt-in PyO3 bindings (the bobine pattern). The crate layering: providers/probe/policy/acquire/error/diag are the shared ONNX plumbing (session building, provider fallback, CUDA probing, HF acquisition); jina is the frozen text-embedding contract.

Provenance: a clean move out of OKFgraph’s rust/okf-embed (itself an exact port of EmbeddingEngine._encode, pinned by that repo’s parity harness at ≤1e-5). Session/threading choices follow EmbedAnything’s ort_jina.rs; device fallback semantics mirror bobine: CUDA is opportunistic, never fatal.

Module layout

• error — anyhow-based error plumbing (oe stringification)
• providers — provider-name matrix + clone-and-fallback application
• probe — corrected CUDA availability check (OnceLock-cached)
• policy — DeviceReq + explicit SessionPolicy (text vs defaults)
• acquire — validated HF hub acquisition (blocking, cached)
• diag — OrtReport observation for logs and diagnostics
• jina — JinaV5 + TokenizerHandle (the frozen contract)
• vision — JinaV5Vision (the dynamic-grid image contract)
