Provenance semirings

Core idea

Provenance semirings represent lineage algebraically so derived results preserve exactly which source facts or branches contributed to them.

Harness takeaway

Branch merges, cherry-picks, evidence bundles, and derived artifacts in the studio should preserve explicit lineage expressions rather than flattening their ancestry.
