Follow-up to the planner WS reconnect-loop incident. Proposes compactly encoding the computed route in the Yjs session doc (single-source geometry + delta/varint polyline + run-length-encoded road metadata, dual-format backward-compatible reads) to cut a ~305 KB / 77 km route to ~40–60 KB — WITHOUT changing the routing-host "compute once, share via Yjs" model or GPX export output. Artifacts: proposal, design, specs (new planner-route-encoding capability), tasks. Validates --strict. Ready for /opsx:apply. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |
