- move self-hosted Convex infra and root placeholder into recycle - update architecture docs to remove active infra/convex deployment guidance - extend local-first Convex guard to block retired infra regressions
- replace default Convex control-plane wording with Rust SQLite control-plane across architecture, AGENTS, Reasonix, and design docs - retire root Convex functions source and deploy script into recycle while keeping explicit cloud/compat/sync-replica boundaries - add control-plane migration guard/docs and keep CodeGraph refreshed after the SQLite control-plane cutover
