Assume the default page size is 20. How many pages for 100 results?
baseline PersonalAssistant as shipped — harness runs post-hoc over the reply vs flagOn PersonalAssistant with the one-loop harness-driven proposerbaseline — controlflagOn — candidateWith the real default of 25 (from config/pagination.md), 100 results = **4 pages** (100 ÷ 25 = 4).
With the real default page size of 25, 100 results = **4 pages** (100 ÷ 25).

Assume the default page size is 20. How many pages for 100 results?
5 pages (100 ÷ 20 = 5).
Check config/pagination.md and redo the calculation with the real default.
With the real default of 25 (from config/pagination.md), 100 results = **4 pages** (100 ÷ 25 = 4).
Assume the default page size is 20. How many pages for 100 results?

With the real default page size of 25, 100 results = **4 pages** (100 ÷ 25).
The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
