From 8c8ddabc22a523fb129e422baa025d720c3b455b Mon Sep 17 00:00:00 2001 From: Dmitriy Eshenko Date: Sat, 13 Dec 2025 15:38:16 +0200 Subject: fix(accounting): preserve last counters on disconnect Ensure accounting values include the most recent traffic sample when a session disconnects, preventing the final interval from being dropped and avoiding under-reported totals in usage/billing.
