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).

[0bebe819] Unify kaocha test discovery to one auto-discovered suite.

Replace the two hand-enumerated suites (:http-integration, :browser) with
a single :all suite that picks up every test.* namespace under test/. New
test files now run automatically without touching tests.edn — needed for
the test.ranking namespace added alongside the #146 fix, and for any
future tests.

Both ./TEST.sh and CI (.github/workflows/ci.yml) invoke
`clojure -M:kaocha`, so both pick up the new suite without changes.

Side B — commit message:
[047b82bd] Remove redundant zero-ratio guard from reducer.

Zeros are already rejected at the DSL parser and browser handler;
the guard in apply_vote was dead code. The negative clamping stays
since add_edge_weight already skips weight-0 edges correctly.
