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 A — contributor: tommy-mor
Side A — 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
- Rename route /vote/compare → /vote

Side B — commit message:
[6b6eb0c3] Auth form: poem JS morphs form innerHTML on response; no redirect

- post_choose_username returns HTML fragments instead of redirects:
  success → auth_signed_in_fragment ("you're signed in — return to your agent")
  error   → choose_username_error_fragment (form re-rendered with error inline)
- Poem JS now reads response body; if non-empty, morphs form innerHTML with it
  (existing ingest forms return empty body, so they're unaffected)
- auth.rs: keep full layout() with poem JS — revert to single layout
- auth-success CSS class added to both themes
