pub async fn write_bridge_pointer(
dir: &str,
pointer: &BridgePointer,
) -> Result<(), String>Expand description
Write the pointer. Also used to refresh mtime during long sessions — calling with the same IDs is a cheap no-content-change write that bumps the staleness clock. Best-effort — a crash-recovery file must never itself cause a crash. Logs and swallows on error.
