Plan and limit changes
Every plan or limit change the coding-agent subscriptions made in 2026, newest first, with what the bench measured on the affected agents in the last weekly run before the change and the first one after it.
The measured line is each affected agent's share of its own plan's weekly limit for one full bench pass (every suite it graded that week, added up, the rule the Overall view uses), read from the published history. Grading started in W32 2026, so changes before August have no run on the near side. A change with no run after it yet says so. 24 of 29 entries link a source that was fetched and confirms the claim; the rest wear an unverified chip until they do. Announcement dates are the provider's; the runs are ours.
