nanobot Spent Two Days Fixing Reconnect-Safe Mutation Replay in Its WebUI — the Unglamorous Half of Self-Hosted Agents
HKUDS/nanobot, the ultra-lightweight self-hosted personal agent framework at 47,091 stars, pushed a run of fixes on 2026-08-15 and 2026-08-16 making WebUI mutations reconnect-safe, snapshotting mutation replay frames, preserving mutation order after reconnect, and hardening replay test coverage. The same window added atomic model-preset renames with inline conflict detection, serialized gateway configuration updates, and preserved legacy OrcaRouter custom configs. Its last tagged release remains v0.3.0 from 2026-07-25, so this is unreleased mainline work — but it is the failure mode every long-running self-hosted agent UI hits, and worth reading before you write your own.
