limits
what this result does not prove
- This is one owner-finalized partial personal assessment of one run, not a universal ranking.
- Execution was interrupted. Saved outputs were assessed as delivered; the original execution and evidence remain incomplete.
- The score belongs to the full setup: model, harness, tools and settings.
- Pack 3.0.0 scores compare only with other pack 3.0.0 results, not with v1 or v2 results.
- The API-equivalent estimate covers 9 of 14 execution records. Tasks marked not recorded have no priced usage.
- Actual incremental spend is unknown because the run used existing subscriptions.
- The build window was four hours. Native live sessions were timed separately from the build window.
The owner rated the saved outputs of each of the ten v3 tasks, plus autonomy and proactivity, in a named single-model review. The saved scores were then finalized as a partial personal assessment and locked. Quality is the weighted task score. v1 to v3 use 70% quality, 20% autonomy and 10% proactivity.
