…reshold Self-review fixes folded in: - Token-aware fail-closed read: const mainQuota = quotaManager.getMain(auth.access) so a previous main account's cached quota can't satisfy the fail-closed check or feed the killswitch eval after a main-account switch. - Removed a stray inner 'let sessionRequestCount = 0' + unconditional increment that shadowed the process-scoped counter, which had left the active-route fallback every-N refresh reading a never-incremented counter.
