~x-ai/grok-latest → B (2:5)

B permanently collapses dual-path epoch/commit rendering to Evidence envelopes only—deleting _legacy_commit_row/_legacy_observation and GitDiscovery projections, tightening Emission fields, and updating tests—so the ledger UI has one durable source of truth. A’s fullscreen compare shell, edge-history sort/ratios, and post-success preview morph are real product polish with tests, but they layer feature UX on garden voting rather than removing systemic ambiguity.
