Weekly token budget was fully exhausted within ~2 days on June 19-20, 2026

consumed immediately after reset.

What steps can reproduce the bug?

on June 19-20, vs. normal 81-198/day

• Up to 632 concurrent session_loop entries within a single second
• 248 sessions spawned in 2 days by a parallel review workflow

Weekly token budget should last ~7 days with normal usage.

Actual behavior

Budget exhausted in <2 days; even after voucher reset it was
consumed immediately by the ongoing parallel workflow.
