The file `/home/node/.claude/projects/-home-node/3b1aded9-1aa8-4cfd-8b4f-f6fcbe625958/tool-results/mcp-claude_ai_mcp-server-forgejo_forgejo_get_file-1779506373972.txt` is JSON with schema `{result: string}` where `result` is the HTML/JS source of a Dragonflight recorders page (services/web-ui/public/recorders.html).

Probe the structure with jq, then extract the full content with `jq -r .result`. I need to understand:

1. Where the "Start Recording" / "Stop Recording" buttons are wired up - which JS function they call, and which API endpoint they hit.
2. Whether there's any field/input for naming a clip before starting a recording. (Currently clip names are auto-generated as `${recorderName}_YYYYMMDD_HHMMSS` — I want to know if the UI lets the user provide a name.)
3. Where the recorder cards/list are rendered. Quote the relevant JS code that handles starting a recording (the section that calls POST /recorders/:id/start).
4. Look for any references to "clipName", "clip_name", or "clip" in the file.
5. Total length of the result string, and rough breakdown of how the file is organized.

Quote relevant code verbatim with line/section context. Be thorough — I'll be modifying this file to add a clip-naming input.


I'll probe the file structure and extract the relevant content.

`startRecorder`/`stopRecorder` aren't defined in this file. Let me check imports/script tags.


619:<script src="js/api.js?v=6"></script>
620:<script src="js/topbar-strip.js?v=1"></script>
621:<script src="js/bmd-card.js?v=1"></script>
622:<script>
1517:<script src="js/auth-guard.js"></script>


`startRecorder`/`stopRecorder` are defined in `js/api.js`. Now let me read the relevant sections of the HTML.

## File overview

- **Path embedded in file**: `services/web-ui/public/recorders.html`
- **`result` string length**: **69,938 characters** (1,520 lines after `jq -r`).
- **JSON schema**: `{ result: string }` — single key, no extra metadata.

### Rough organization

| Lines       | Section                                                                                |

| 371-615     | Slide panel `#recorderPanel` (the create/edit form). All form inputs live here (recorder name, source type, master/proxy codec blocks, destination project/bin). |

- 769-797: `loadBmdDevices()` — fetches `/api/v1/cluster/devices/blackmagic`
- 799-972: `loadRecorders()` / `renderRecorders()` — main render loop (this is where the Stop/Record buttons are emitted)
- 974-1016: signal badge & duration helpers
- **1018-1036: `handleStart` / `handleStop` / `handleDeleteRecorder`** — controls
- 1038-1180: `openPanel()`, `openEditPanel()`, `closePanel()`
- 1182-1324: source-type fields + BMD/SDI picker
- 1326-1343: `loadProjects` / `handleProjectChange`
- 1345-1405: probe (`/api/v1/recorders/probe`)
- 1407-1502: `handleSaveRecorder` (POST/PATCH recorder config)
- 1504-1515: `toast()` + `esc()` helpers

## 1. Start/Stop button wiring

### Where the buttons are rendered (inside `renderRecorders`, lines 908-918)

```js
        <div class="recorder-footer">
          <span class="recorder-footer-meta">Last: ${lastRec}</span>
          <div class="recorder-controls">
            ${isRecording
              ? `<button class="wd-btn wd-btn--danger wd-btn--sm" onclick="handleStop('${rec.id}')">Stop</button>`
              : `<button class="btn btn-record btn-sm" onclick="handleStart('${rec.id}')">
                  <svg viewBox="0 0 14 14" fill="currentColor" width="10" height="10"><circle cx="7" cy="7" r="5"/></svg>
                  Record
                 </button>`
            }
          </div>
        </div>
```

(The button visually says "Record" / "Stop", not literally "Start Recording" / "Stop Recording" — that's why the case-insensitive grep for "Start Recording" returned nothing.)

### The handlers (lines 1018-1029)

```js
  // ── Controls ──────────────────────────────
  async function handleStart(id) {
    const r = await startRecorder(id);
    if (r.success) { toast('Recording started', '', 'success'); loadRecorders(); }
    else toast('Failed to start', r.error, 'error');
  }

  async function handleStop(id) {
    const r = await stopRecorder(id);
    if (r.success) { toast('Recording stopped', '', 'success'); loadRecorders(); }
    else toast('Failed to stop', r.error, 'error');
  }
```

### Endpoint location

**`startRecorder(id)` and `stopRecorder(id)` are NOT defined in `recorders.html`.** They are imported via `<script src="js/api.js?v=6">` (line 619). To see the literal `POST /api/v1/recorders/:id/start` call you'll need to read `services/web-ui/public/js/api.js`. The only direct `fetch()` calls hitting `/recorders/*` from this file are:

- Line 690: `GET /api/v1/recorders/${rec.id}/status` (signal polling)
- Line 772: `GET /api/v1/cluster/devices/blackmagic`
- Line 1360: `POST /api/v1/recorders/probe`

Everything else (`getRecorders`, `startRecorder`, `stopRecorder`, `createRecorder`, `patchRecorder`, `deleteRecorder`, `getProjects`, `getBins`) lives in `api.js`.

## 2. Clip-naming input — does it exist?

**No.** Grep results:

- `clip` (case-insensitive): **0 matches** in the entire 1520-line file.
- `clipName`, `clip_name`: 0 matches.

The slide panel (lines 380-609) only has inputs for: recorder name (`#recName`), source type, codec/resolution/bitrate/framerate/container (master + proxy), project, and bin. There is **no per-recording clip-name input anywhere** — neither in the recorder card UI nor in the panel. The `handleStart(id)` call takes only the recorder id and posts no body fields.

This confirms your assumption: clip names are entirely server-generated (`${recorderName}_YYYYMMDD_HHMMSS`) with no UI override path.

## 3. Recorder card rendering

`renderRecorders()` (lines 807-972) builds the entire grid via a single `grid.innerHTML = pState.recorders.map(rec => { ... }).join('')`. Highlights for your modification:

- Lines 819-823 implement a render-skip optimization keyed by `id:status:live_asset_id:started_at` — **if you add a per-recorder clip-name input you may need to either include the input in the signature or render the input outside this innerHTML rebuild path** (otherwise the 5-second `loadRecorders` interval will wipe whatever the user typed, unless the signature key remains stable).
- The card root is at line 871: `<div class="recorder-card ${statusClass}" data-id="${rec.id}">`
- The natural place to add a clip-name `<input>` is between the `recorder-source` block (line 901) and the `recorder-footer` (line 908), or as a sibling inside `.recorder-controls` (line 910) immediately to the left of the Record button.

### Card-emission template, with the Start button in context (lines 871-920)

```js
      return `<div class="recorder-card ${statusClass}" data-id="${rec.id}">
        <div class="recorder-header">
          <div class="recorder-id">
            <div class="recorder-name">${esc(rec.name)}</div>
            ...
          </div>
          <div class="recorder-actions"> ... </div>
        </div>

        <div class="recorder-status-row"> ... </div>
        ...

        <div class="recorder-source">
          <svg .../>
          <span>${esc(sourceDisplay)}</span>
        </div>

        ${connectBanner}

        <div class="recorder-footer">
          <span class="recorder-footer-meta">Last: ${lastRec}</span>
          <div class="recorder-controls">
            ${isRecording
              ? `<button class="wd-btn wd-btn--danger wd-btn--sm" onclick="handleStop('${rec.id}')">Stop</button>`
              : `<button class="btn btn-record btn-sm" onclick="handleStart('${rec.id}')">
                  <svg viewBox="0 0 14 14" fill="currentColor" width="10" height="10"><circle cx="7" cy="7" r="5"/></svg>
                  Record
                 </button>`
            }
          </div>
        </div>
      </div>`;
```

To pass the clip name to the backend, you'll likely want to:
1. Add an `<input id="clipName-${rec.id}" placeholder="Clip name (optional)">` near the Record button.
2. Change `handleStart(id)` to read that input: `const clipName = document.getElementById('clipName-' + id)?.value.trim() || null;` and pass it to `startRecorder(id, { clipName })`.
3. Extend `startRecorder` in `js/api.js` to send `POST /api/v1/recorders/:id/start` with a JSON body `{ clip_name }` (currently presumably called with no body).
4. Watch the rerender-signature optimization at line 819-823 — preserve the typed-but-unsubmitted value across the 5s polling refresh (either save into `pState` on `input` events, or restore from DOM in the next render).

## 4. References to "clip*"

Confirmed: **zero occurrences** of `clip`, `Clip`, `clip_name`, `clipName`, or any variant in the file. You are starting from a blank slate for clip-naming UI.
