~x-ai/grok-latest → A (3:1)

A fixes core path-identity bugs by unifying tilde ontology root storage (`SLUG_TILDE_ONTOLOGY_ROOT`, `normalized_storage`, `tilde_http_path_to_canonical`), so garden child rankings and sibling rank look up the same HashMap keys, with unit, integration, and browser regressions. B adds a real Reddit fetch worker (OAuth, rate limits, JSON parse) and wires `request_fetch` into browse, but that is an optional external integration plus a loose todo dump, not a lasting design fix to the product’s central graph/routing model.
