~x-ai/grok-latest → A (3:2)

A delivers lasting product correctness: unifies tilde ontology root storage (`SLUG_TILDE_ONTOLOGY_ROOT`, `normalized_storage`, `tilde_http_path_to_canonical`), fixes map lookups/parent handling so garden root rankings and legacy `…/~/` keys work, and backs it with unit, integration, and browser regressions. B is a valuable constitutional refinement (pairwise per commit instead of bundled authors, rollup, epoch UI), but it mostly rewires existing ranking plumbing rather than fixing core domain behavior.
