Subject: [PATCH] docs: verify issue #605 video scenes dataset

Add a verification note and regression test showing that
training/data/prompt-enhancement/video-scenes-500.jsonl already
exists on main with 500 valid records.

+# Issue #605 Verification
+
+Status: already implemented on `main`.
+
+Issue: Prompt Enhancement: Video Scenes — 500 Terse→Rich Pairs
+
+What is already present on `main`
+- `training/data/prompt-enhancement/video-scenes-500.jsonl`
+- 500 JSONL records
+- every record includes `terse`, `rich`, and `domain`
+- every `domain` value is `video scenes`
+- 500/500 full records are unique
+- every `rich` prompt includes video-scene structure markers for `lighting`, `composition`, and `transition`
+
+Evidence gathered from a fresh clone
+- validation against `training/data/prompt-enhancement/video-scenes-500.jsonl` returned:
+  - `count = 500`
+  - `unique_records = 500`
+  - `unique_terse = 120`
+  - `domains = ['video scenes']`
+  - `missing_keys = 0`
+  - all 500 `rich` prompts contain `lighting`, `composition`, and `transition`
+- closed PRs `#755` (`fix/605`) and `#648` (`feat/605-video-scenes-prompts`) show prior attempts on this lane
+- SHA-256 of `training/data/prompt-enhancement/video-scenes-500.jsonl` on `origin/main` matches the same file on remote branch `fix/605`, which shows the requested dataset is already present on `main`
+
+Verification commands
+```bash
+python3 - <<'PY'
+import json
+from pathlib import Path
+path = Path('training/data/prompt-enhancement/video-scenes-500.jsonl')
+records = [json.loads(line) for line in path.read_text().splitlines() if line.strip()]
+print('count', len(records))
+print('unique_records', len({json.dumps(r, sort_keys=True) for r in records}))
+print('unique_terse', len({r['terse'] for r in records}))
+print('domains', sorted({r.get('domain') for r in records}))
+print('missing_keys', sum(any(k not in r or not str(r[k]).strip() for k in ('terse', 'rich', 'domain')) for r in records))
+print('lighting_count', sum('lighting' in r['rich'].lower() for r in records))
+print('composition_count', sum('composition' in r['rich'].lower() for r in records))
+print('transition_count', sum('transition' in r['rich'].lower() for r in records))
+PY
+```
+
+Recommendation
+- Close issue #605 as already implemented on `main`.
+- This branch only adds a durable verification note and regression test so the open issue can be closed cleanly without regenerating duplicate training data.
