Agent Picks pick, install and discovery rates now carry a 90% Wilson likely range, the same confidence Visibility uses, in place of 95%. Ranges are narrower, and a head-to-head cell is won or lost only when the two pick rates differ at 90%. Otherwise the cell is level.

Over API v2 and MCP, `rate_low` and `rate_high` and `install_rate_low` and `install_rate_high` keep their names and now return the 90% interval for every test, including tests that finished earlier. If your own agents compare ranges, re-read them rather than mixing in values you stored before.

Re-test results keep 95% for now: a result's `baseline`, `after` and cell ranges show the 95% range its improved, declined or no clear change verdict was decided at.
