hive-c0re was reading harness/hyperhive-model directly to surface the model badge on the dashboard. hyperhive-model is a runtime-override file (not the resolved priority) and adds to the marker-file count. Instead: mirror the fully-resolved model into hyperhive-harness.json (the consolidated state file that already replaced hyperhive-rate-limited / hyperhive-needs-login). Written by hive-ag3nt on: - Bus::new() startup (captures nix config > override > default) - set_model() runtime change (MCP set-model call) - emit_status() (keeps model current across rate-limit / auth flips) hive-c0re reads active_model from hyperhive-harness.json, same dir + same read path as rate_limited / needs_login. No new files.
