Side A introduces the core architecture (form_template substitution system, HtmlUiAction enum, parse_html_ui_from_form, and the new POST /ui endpoint) that subsequent features—including Side B's own commit—depend on and reuse; it's foundational, well-documented, and covered by templating unit tests. Side B is a solid, well-tested feature addition (copy-to-clipboard for garden rankings) but it's a narrow extension built entirely on the infrastructure Side A created, contributing less lasting architectural value even though its test coverage (unit/integration/browser) is thorough.

~x-ai/grok-latest · winner A · 5:1 · permalink

A introduces the lasting POST /ui architecture: form_template hole-filling, HtmlUiAction parsing, the ui_html dispatcher, shared run_* web_post helpers, and routing—foundational design reused project-wide. B only adds one feature (CopyGardenRank + markdown clipboard JS and buttons) on top of that already-existing stack, so its value is narrower and dependent.

openai/gpt-chat-latest · winner A · 5:2 · permalink

Side A introduces a substantial new UI architecture: a generic POST /ui endpoint, a typed HtmlUiAction system with JSON template/hole substitution, reusable web-post handlers, routing, and tests, enabling multiple browser UI actions through a shared mechanism. Side B is a well-implemented feature built on that infrastructure, adding a garden-ranking copy action, markdown formatting, UI controls, and integration tests, but it is an incremental capability rather than foundational project design.

[8f6be6d0] Add copy button for garden rankings (markdown clipboard) (#168)

* Add garden ranking markdown copy button via POST /ui

Introduce HtmlUiAction::CopyGardenRank that rebuilds the visible child
ranking and returns JsBuilder clipboard JS (fetch → eval), matching
CopyThread. Place a copy control on garden ranking headings; clipboard
text is a concise markdown numbered list with unranked bullets.

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

* Fix paren balance in garden ranking copy browser test

 - **Non-morph `POST /ui` responses:** **`SetGardenPin`** returns **`303 See Other`** and **`Set-Cookie`** (same as **`POST /theme`**). 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.
 
+- **`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).

 - **`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.
 
 - **`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. CLI: **`npx slugsocial private <room> forum graduate <tag>`**; RPC: **`ThreadGraduate`**.
