~anthropic/claude-sonnet-latest → B (6:4)

B undertakes a substantive architectural fix: it separates the previously conflated 'thread_id' (used both as a permission boundary and forum channel) into distinct room_id/thread_tag concepts, replaces scattered REST endpoints with a unified RPC batch API, and updates all tests/CLI/integration scripts to match the new model coherently. A is a smaller, well-tested feature (explicit Reddit fetch-on-demand plus event-sourced entity import) but touches a narrower surface than B's system-wide correctness improvement, even though B's commit message signals it's a rougher first pass.
