boring-semantic-layer v0.3.13

Highlights

This release adds metadata support on model fields, expands xorq/TagHandler integration, improves MCP tooling, and fixes several round-trip and serialization correctness issues.

• Added metadata field on Dimension and Measure for arbitrary annotations (#245, #246)
• Exposed BSL TagHandler via xorq.from_tag_node entry point for catalog workflows (#235)
• Added reemit support on TagHandler for full catalog rebuild (#244)
• Added MCP period comparison workflow (#238)
• Fixed join rebind guard for non-xorq backends (#242, #243)
• Fixed multiple round-trip and serialization correctness issues in xorq boundary and calc-measure handling

Why upgrade

• If you use metadata on dimensions or measures, this is the release that adds it
• If you're integrating BSL with xorq catalog workflows, the new TagHandler entry points make that cleaner
• Several xorq serialization round-trip bugs are fixed — recommended if you serialize/deserialize semantic models

Included changes

Features

• #238 — MCP period comparison workflow
• #244 — TagHandler reemit for catalog rebuild
• #245/#246 — metadata field on Dimension and Measure
• #235 — expose BSL TagHandler via xorq.from_tag_node

Fixes

• #242/#243 — guard join rebind against non-xorq backends
• Fix: walk join branches in tag_handler.extract_metadata
• Fix: roundtrip model-level description through to_tagged/from_tagged
• Fix: preserve join cardinality on round-trip; fix pre-agg grain for derived dims
• Fix: treat UnboundTable as leaf node in _reconstruct_table
• Fix: use matching ibis module for desc() in MCP search_dimension_values
• Fix: broaden agg-method recognition, surface typos, pin ibis workaround

Refactors

• Introduce Predicate AST for filter expressions
• Tighten calc-measure AST and surface type-inference failures
• Route all xorq imports through single _xorq shim
• Convert ibis→xorq once at SemanticModel construction
• Dispatch reduction-type check on expr's ibis flavor
