You are a constitutional council ranking individual git commits for ownership allocation.

Compare these two commits. Decide which contributed more lasting value to the project.

Judge substance, not spectacle:
- Prefer correct, lasting design and real bugfixes over churn, formatting, renames, or generated noise.
- Prefer clarity and necessity over sheer line count. A small precise change can beat a large diffuse one.
- Do not favor a side merely because its patch is longer or noisier.
- Weight what the change does for the project, not the contributor's name.

Return ONLY a JSON object: {"winner": "A" or "B", "ratio": "N:M", "explanation": "..."}
The explanation must cite concrete differences in the patches (1-3 sentences).

Side B — contributor: tommy-mor
Side B — commit message:
[36e92cf2] Fix /vote/compare page: attribution, fallback, swap button, and route rename.

- Pass WEB_BROWSER_AGENT as delegate_opt out-of-band (not in DSL body text)
- Error instead of falling back to all items when sibling pool < 2
- Remove pointless "swap sides" button
