Walkthrough

The change adds MxbaiEdgeColbert for mixedbread-ai/mxbai-edge-colbert-v0-17m to the late-interaction model registry. The model uses 48 dimensions, lowercase tokenizer normalization, and a single-threaded embedding worker. Tests add canonical document and query embedding fixtures and check the reported embedding size.

Priority: Normal

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: Low · up to 7cda8

Surrounding whitespace can produce embeddings that differ from the reference. Callers can trim inputs until preprocessing is corrected.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 3 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Review comments at @fastembed/late_interaction/mxbai_edge_colbert.py:
- Line 46: Update the document and query preprocessing around the Lowercase
normalizer so both inputs receive strip-then-lowercase normalization before
encoding and token counting; ensure raw [MASK] is lowercased rather than
exempted from normalization.
