# R3 warm-same-branch

Evidence for [#33263](https://git.cafe/pingdotgg/t3code/pull/33263). Control unchanged: A remote payload is byte-for-byte equal before/after the local edit; only localUpdated is published.

The only fetch is the initial warming full refresh; local-only refresh starts no remote read.

The recordings below preserve action/event order independently in each column. Rows align by event ordinal, not wall-clock synchronization. Full payloads, command traces, and server completion spans are in the linked logs. Bounded windows establish only the recorded absence of an update, not a full 30-second delay.
