[0.4.0] - 2026-10-10

Changed (behaviour change)

  • The default is now the lean preset: a Sonnet ceiling and effort capped at medium. Chosen by a pre-registered rule on 100 more graded runs: 39/40 hard tasks done against 38/40 for always-Opus and always-Sonnet, at $0.064 per run against $0.163 (Opus) and $0.062 (Sonnet); 18/18 on the multi-step set at $0.061 per run. Opus is still used when Jev is at least 90% sure (ceilingBreak). To keep the old behaviour set preset: balanced (or /jev preset balanced).

Added

  • /jev preset lean|balanced|max and a preset option; /jev status shows the active preset.
  • Benchmark harness: > strategy filter, a lean strategy, and an opt-in Wilson interval for pass rates (CI=1). CI checks that the shipped defaults match the lean preset.
