Source words

Words in the local study source for a variant; this is the local authoring burden.

Variable words

Words in a variant's explicit input payload, when a template or refinement uses one.

Output words

Words in the saved compiled final artifact.

Leverage

Output words divided by local source words; larger means more final artifact per local word, not quality by itself.

Fact units

Novelty-weighted semantic fact units extracted from the output by deterministic rules.

Density

Discounted fact units per 1,000 output words; higher means a more information-dense output.

Yield

Discounted fact units per 1,000 local source words; higher means more semantic material per local authoring word.

Contrastive gain/loss scores

Scores compare [T] Expanded WeaveMark treatment against [C2] Matched-prose no-expand control on the -3..+3 scale.

Primary scores are blind* using hybrid-derived-metrics-and-masked-review: anonymous absolute 1..7 scores were frozen before reveal, then converted to the -3..+3 treatment-control scale. Hybrid blind* scoring uses derived metrics for mechanical criteria and masked source/output review for criteria that require actual reading. The masked review is less blind because domain content, source syntax, or style can leak, but this is necessary to avoid replacing readability and integration judgments with weak length/density proxies.

Contrastive score

A -3..+3 judgment comparing [T] against the strongest listed control for each criterion.

Total score

The sum of the seven contrastive criterion scores for one study.

Gains and failures

Gains

  • [T] Expanded WeaveMark treatment wins source-only leverage: 16.36 versus 7.83 for [C2] Matched-prose no-expand control.
  • [T] Expanded WeaveMark treatment wins discounted fact units: 213.5 versus 95 for [C2] Matched-prose no-expand control.
  • [T] Expanded WeaveMark treatment wins information density: 73.7 versus 67.4 for [C2] Matched-prose no-expand control.
  • [T] Expanded WeaveMark treatment wins information yield: 1,206.2 versus 527.8 for [C2] Matched-prose no-expand control.
  • `@expand` makes compact concept labels readable and operational against the compact control.
  • The treatment clearly states the integrated mechanic that connects network drawing, city growth, and demand trails.
  • It now wins the matched-prose control on the deterministic leverage, fact-unit, density, and yield proxies.

Failures and caveats

  • The matched-prose control remains the fairness baseline because it spells out the same inspiration set without `@expand`.
  • The treatment is a longer generated artifact, so this is not an output-brevity claim.
  • This is saved-output semantic evidence; behavioral proof still requires downstream implementation/use.

Conclusion

A useful `@expand` study where compact named inspirations now produce stronger deterministic proxy metrics than matched prose, while still needing behavioral proof.
