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.\n \n+- **`CopyGardenRank`:** Browser copy control on garden ranking headings. Returns **`text/javascript`** via **`JsBuilder::clipboard_write_text_and_label_btn`** (same **`fetch` → `eval`** loop as **`CopyThread`**). Payload includes **`room`**, **`parent_path`**, **`depth`**, **`copy_btn_id`**, and optional **`external_hosts`** (for **`/-/`** host-root indexes). Clipboard text is a concise markdown numbered list of display paths (plus unranked bullets).\n+\n - **`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. **Guests** on a shared pair see the compose UI with **`post vote`** as a link to **`/login?next=<pair path>`** (class **`vote-compare-login-cta`**); after OAuth / username selection they return to that matchup. An unauthenticated **`VoteComparePost`** (forged/stale form) still JS-redirects to the same **`/login?next=`** target.\n \n - **`ThreadGraduate` / `GraduateThread`:** Private-room forum threads with **Manage** can be published to the public site under the same tag. The writer replays non-redacted ingests into **`room: public`** (chronological order), then appends a durable **`ThreadGraduated`** marker. Graduated private threads show a banner linking to public **`/t/:tag`**, block further private posts, and cannot be graduated twice.
