# R8 cold-subscribe-zero

Evidence for [#33263](https://git.cafe/pingdotgg/t3code/pull/33263). Before: null snapshot and no populated remote event in 6.5 seconds. After: the first subscription loads A upstream/ahead 1/behind 0/default-ahead 1. Neither side executes git fetch.

Tracking refs are preseeded; the settings RPC successfully sets the interval to zero. This is the initial-read scheduler path, not a periodic repair.

AI-assisted; verified with the tests and tools listed above.

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.
