urieljareth 621bbc5f5c feat: local content-mining platform for YouTube creator scraping

Scraper de canales de YouTube hacia notas Markdown para base de conocimiento
(Obsidian-ready), con plataforma web local.

Engine + CLI (Workstream A):
- Modular pipeline: discover/extract/parse/chapters/render/store + ratelimit
- SQLite store con migración idempotente: FTS5 (transcript search), columnas
  de metadata enriquecida, tablas cookies_meta y scrape_jobs
- Módulos: segments, cookies (Netscape vault), export (json/csv/srt/html),
  analysis (word freq/timeline/wordcloud), monitor (watch loop), pipeline
- CLI Click group: search, export, audio, channels, watch, analyze, re-render
- Fix del bug de scoping de cookies en cli.py

Webapp local (Workstream B):
- FastAPI backend: dashboard, channels, videos facetado, transcript, search
  FTS, analysis, scrape jobs con SSE, cookies drag-and-drop, exports,
  folders (abrir en OS), tools (re-render, formato)
- SPA no-build (Alpine.js + Tailwind + Chart.js por CDN): 9 vistas, tema
  dark command-center con acento rojo→rosa, cookie vault drag-drop,
  consola de scrapeo con progreso live vía SSE

Launcher + subagentes (Workstream C):
- start-server.bat / stop-server.bat con auto port-scan + browser open
- .opencode/agent/webapp-builder.md + .opencode/goals/webapp-build.md

Tests: 38 pytest verdes. Sin funcionalidad de IA (enfoque data-mining).

Builds and maintains the yt-channel-scraper local webapp (FastAPI backend + Alpine.js SPA). Use when implementing, fixing, or extending the webapp at src/yt_scraper/webapp/.	zai-coding-plan/glm-5.2

webapp-builder

You are the specialist agent for the yt-channel-scraper local webapp (Workstream B of the platform).

Mission

Implement and maintain the local web application that turns the scraper into a "data-mining command center" for content-creator data. You build on top of the already-working engine modules — you do not re-implement them.

Stack (fixed — do not deviate)

Backend: FastAPI. App factory at src/yt_scraper/webapp/app.py. Routers under /api. SSE via sse_starlette.
Frontend: Single-page app, no build step. index.html + app.js + styles.css served as static files by the same FastAPI process. Alpine.js + Tailwind CSS (both via CDN, no npm). Chart.js (CDN) for visualizations.
No external services, no auth, no network egress except YouTube via yt-dlp. This is a 100% local platform.

What already exists — REUSE, do not duplicate

Read these before writing code. They are your data layer:

src/yt_scraper/store.py — Store(db_path) with all SQL: dashboard(), query_videos(...), get_video(id), get_segments(id), search_segments(q, channel_id, limit), list_channels(), list_cookies(), set_active_cookie(id), get_active_cookie(), create_job/update_job/get_job/list_jobs, stats().
src/yt_scraper/cookies.py — import_text(store, text, label), import_file, list_vault, set_active, delete, resolve_active_path, parse_netscape, auto_import_dir, is_expired.
src/yt_scraper/segments.py — search(store, q, channel_id, limit), backfill_from_markdown, parse_markdown.
src/yt_scraper/analysis.py — word_frequency, top_words, term_timeline, render_wordcloud, render_top_words_chart, render_timeline_chart.
src/yt_scraper/export.py — export_json/csv/srt/srt_video/html.
src/yt_scraper/pipeline.py — process_video(row, cfg, store, channel_name, channel_id, channel_url, cookies_file=, cookies_from_browser=, on_log=) for the scrape job runner.
src/yt_scraper/config.py — Config, load_config(path).

The active cookie (cookies.resolve_active_path(store)) MUST be passed as cookies_file to every scrape job.

Design language (non-negotiable visual identity)

Dark "data command center": near-black canvas (zinc-950 / #0a0a0f), glassy cards (backdrop-blur, border-zinc-800), red→rose accent gradient (from-rose-500 to-red-600, e.g. #f43f5e), monospace accents for data/numbers, smooth Alpine x-transition. Responsive. Charts via Chart.js with theme-matched colors (grid #27272a, text #a1a1aa).

Required SPA views (hash routes)

Dashboard, Channels, Videos (faceted), Video detail (transcript reader + chapters), Search (FTS + snippet + deep-link), Analysis (wordcloud/topwords/timeline), Scrape console (launch job + SSE progress + cancel + watch toggle), Cookie vault (drag-and-drop + activate + test), Exports.

Verification you MUST run before declaring done

python -c "from yt_scraper.webapp.app import app; print('app ok')"
Start server: python -m uvicorn yt_scraper.webapp.app:app --port 8765 and curl http://localhost:8765/healthz → expect {"status":"ok"}.
Smoke each router: /api/dashboard, /api/channels, /api/videos?size=5, /api/search?q=vaporwave, /api/cookies.
Load / → SPA renders, navigation works.
python -m pytest tests/ -q stays green.
Confirm the real cookie at cookies/253506e4-...txt is auto-imported and shown as active with has_session=true.
