+## [0.1.1] - 2026-09-26
+
 ### Added
 - `downshift report` shows the one-time analysis cost (eval model calls plus estimated judge
   calls, at config prices) and the payback time. New `--audit-cost USD` option for an
   assistant audit. `downshift export` adds the same numbers to `summary.json`.
+  SupportDesk: $0.65 one-time, pays back in 51 minutes.
 - Web Overview shows the analysis cost and payback time.
+- mem0 case study: 51 eval cases for 3 features and a local reranker run (no safe downgrade;
+  best candidates keep 76% of baseline quality).
+
+### Fixed
+- The judge estimate note only appears when there are judge calls.
+- Clear "No payback" sentence when nothing was downgraded; "1 minute" is singular.
