Shared result + provenance contract for the sleap-roots <-> Bloom pipeline.

sleap-roots-contracts

Shared result + provenance contract for the sleap-roots ↔ Bloom pipeline.

This is a small, dependency-light, Bloom-agnostic library that defines the shape of a per-scan pipeline result and its provenance (Pydantic v2 models), emits a versioned JSON Schema artifact, and ships a trait-definitions registry. The Python producers (sleap-roots-predict, sleap-roots-traits) import it; Bloom consumes the emitted schema.

It also defines the analysis-input contract — the canonical shape of the wide trait table that crosses the sleap-roots-analyze ↔ Bloom boundary. validate_analysis_input(df, *, strict=False) structurally validates that table against fixed canonical role names (genotype + optional sample_id / replicate / image_path) plus an open set of opaque numeric trait columns, returning a structured ValidationResult. It operates on a pandas DataFrame, so pandas is an optional install extra — pip install sleap-roots-contracts[pandas] — while the runtime core stays pydantic + pyyaml. Canonical example tables ship in the package (sleap_roots_contracts.examples.load_analysis_input_example(...)) so consumers can load a validating frame straight from the released wheel.

It is sub-project #1 of the sleap-roots ↔ Bloom integration program. Design and plan: docs/01-contract-library-design.md and docs/02-contract-library-plan.md.

Key ideas

• Pydantic is canonical; schema/*.json is generated and drift-guarded in CI.
• Trait values are long-format rows (no jsonb); provenance is a jsonb blob on the source.
• Hashes (param_hash, idempotency_key) are producer-side only; Bloom treats them as opaque strings.
• Distributed via PyPI (no Docker image — this is a library).
