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 — commit message:
[23c8134e] Fix /-/ external garden index; resolvers/ + GitHub import cards (#150)

* Fix external garden root listing; add resolvers/ with GitHub cards

The public and room external index pages queried children of a bogus
https://./ parent, so /-/ always looked empty. Collect host-only https
roots from all Web items and item_children edges so ghost parents from
add_child_edge appear.

Move GitHub resolver into server/src/resolvers/ with default_external.rs
and a try_render_resolver_item_body hook. Resolver ingests now store
slug-github-card fenced JSON; render_item_body_in_scope shows a small
GitHub article card (with legacy support for schema-less json fences on
github.com URLs). Styling in theme_default.css; agents.md updated.

Co-authored-by: tommy <thmorriss@gmail.com>

* Vote compare: GitHub cards in columns, layout CSS, tests

Pass item_bodies into vote_compare_item_card for linkified tooltips on
non-card bodies; clone item_bodies before dropping reducer read guard.

Add layout rules so rich cards sit in the grid corners (default + retro).

Unit test on vote_compare_item_card; integration GET /vote/compare with
ingested slug-github-card bodies. agents.md clarifies compare columns.

 - **`VoteComparePost`:** On success returns **`text/javascript`** that **morphs** **`#vote-edge-history-region`** (recomputed **`<ul>`** — ratios match **`left`/`right`** query order, bullets, sorted by strength toward **`left`** then newer) and **`.vote-compare-nav`** (fresh next-pair link). The compare **`GET`** page uses **`layout_full_bleed_chromeless`** (no breadcrumbs, no **`#controls`**, no **`slug-pin-hud`**; **`view-vote-compare-fullscreen`** full-width **`body`**). **`__rpc__`** carries **`form_action: "/ui"`**; **`thread_tag`** and ratio fields come from the same form as **`$form`** holes.

Resolver results are durable system ingests, while cooldown state is RAM-only.
+- **`ResolveExternal`:** GitHub resolver buttons are browser actions through **`POST /ui`**. Success responses morph **`#external-resolver-status`** then redirect to the sanitized shareable **`GET`** page so imported children render through the normal page path; errors morph the same status region. Resolver results are durable system ingests, while cooldown state is RAM-only. Implementation lives under **`server/src/resolvers/`** (GitHub resolver + import card JSON); ontology item pages and the **`GET /vote/compare`** left/right columns use **`render_item_body_in_scope`** in **`server/src/html/mod.rs`**, which calls **`server/src/resolvers/mod.rs::try_render_resolver_item_body`** before falling back to the usual **`<pre>`** linkified view.
 
 - **Garden pin / compare voting:** Cookie **`slug_garden_pin`** via **`set_garden_pin`**. Pairwise UI: **`GET /vote/compare?…`** / **`GET /r/:room_key/vote/compare?…`** (fullscreen **`GET`** page: no HUD; other garden pages). HUD (**`#slug-pin-hud`**): only when **`layout`** passes garden metadata on **`body`**; the label is **`POST /ui`** **`set_garden_pin`** **`clear:true`** (**`slug_ui.js`**), not a permalink to the item.
