nic-6443 opened a new pull request, #14017:
URL: https://github.com/apache/apisix/pull/14017

   The `$rate_limiting_info` section added in #13996 says the delayed-sync 
snapshot is only refreshed after its window has ended. That's wrong. `sync_key` 
replaces it through `sync_to_shm` on every periodic synchronization, which runs 
within `sync_interval` after a request (since #14015 also when there is no 
local delta), and the snapshot is refreshed again when it expires at the end of 
its window.
   
   This corrects the sentence in en and zh. What it was explaining still holds: 
a request that arrives after a window boundary but before the next 
synchronization is still checked against the previous snapshot, so its 
`evaluated_at_ms` can briefly be later than `current_window.end_ms`.
