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).

[075d4d37] Fix OAuth test mocks so Clojure E2E auth flows work again.

HttpServer handlers were crashing on query parsing and token POSTs, which broke Playwright login; also read alias/history via real CSS selectors.

[bda5f8aa] Remove legacy evidence projection; Evidence envelopes only.

Epoch and commit pages no longer invent history from bare GitDiscovery rows. Production ledger will be wiped to re-emit under the current schema.
