~x-ai/grok-latest → B (2:3)

B makes a lasting architectural correction by deleting EntityStore/EntityImported, stopping raw Reddit payloads from entering the durable event log, writing display fields only as TTL-evicted projection cache, and keeping NodeEnsured/votes/structure as the sole logged facts—directly reducing retention/compliance risk and long-term log bloat. A adds a solid, well-tested URL DFA/canonicalization graph (parse, builder, Reddit/YouTube rules, generic fallback), but that is additive domain logic rather than a core persistence-model fix.
