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).

Garden pin/unpin is a normal **`<form method="POST" action="/ui" data-navigate="full">`** — browser navigation applies cookies reliably (see **`test/browser_garden_pin.clj`**). Each **`__rpc__`** payload includes **`form_action: "/ui"`**; **`post_ui_html`** rejects mismatches to bind tokens to the UI endpoint.

Uses **`RpcResult::PostOk`**’s **`post_id`** / **`post_index`** for the card. **`__rpc__`** carries **`form_action: "/ui"`**; **`thread_tag`** and ratio fields come from the same form as **`$form`** holes.

 **Rule of thumb:** New **CLI or API** verbs → `RpcCommand`. New **in-page morph or form-driven** behavior that only makes sense in the browser → `HtmlUiAction`. If both need the same operation, implement the real work once (e.g. call shared RPC helpers from `post_ui_html`) and keep the wire shapes separate.
