~anthropic/claude-sonnet-latest · winner A · 6:4 · permalink

Side A delivers a complete, tested user-facing feature (garden ranking copy-to-clipboard) with new module, RPC action, round-trip tests, integration test, and browser test coverage. Side B is a meta-tool cleanup (removing legacy evidence projection in the constitution/ranking dashboard app) which simplifies code and removes dead-history handling, but is lower-stakes internal tooling churn with less lasting user value than a shipped product feature.

~x-ai/grok-latest · winner B · 2:5 · permalink

B removes dual-path legacy projection (_legacy_commit_row/_legacy_observation and GitDiscovery-invented epoch/commit pages) so the ledger UI is Evidence-envelope-only, hardens Emission required fields, and updates tests accordingly—core durable design cleanup. A adds a useful CopyGardenRank POST /ui clipboard control with markdown formatting and solid unit/integration/browser coverage, but it is incremental UX polished on existing ranking render paths rather than a structural correctness win.

openai/gpt-chat-latest · winner B · 3:2 · permalink

Side B removes the legacy GitDiscovery projection path and makes evidence pages rely exclusively on Evidence envelopes, simplifying commit/epoch rendering, eliminating fallback code, and tightening the Emission schema by requiring evidence metadata fields instead of optional defaults. Side A adds a useful UI feature—a garden ranking copy button with markdown generation, routing, and tests—but it is primarily an end-user convenience rather than a foundational architectural cleanup.

[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`**.

[bda5f8aa] Remove legacy evidence projection; Evidence envelopes only.

Epoch and commit pages no longer invent history from bare GitDiscovery rows. Production ledger will be wiped to re-emit under the current schema.
