+# Repository Guidelines
+
+## Project Structure & Module Organization
+- Core modules live under `python_app/`: `config.py` centralizes settings, `transcript_collector.py` gathers transcripts, `ingest.py` handles Elasticsearch bulk loads, and `search_app.py` exposes the Flask UI.
+- Static assets belong in `static/` (`index.html`, `frequency.html`, companion JS/CSS). Keep HTML here and wire it up through Flask routes.
+- Runtime artifacts land in `data/` (`raw/` for downloads, `video_metadata/` for cleaned payloads). Preserve the JSON schema emitted by the collector.
+- When adding utilities, place them in `python_app/` and use package-relative imports so scripts continue to run via `python -m`.
+
+## Build, Test, and Development Commands
+- `python -m venv .venv && source .venv/bin/activate`: bootstrap the virtualenv used by all scripts.
+- `pip install -r requirements.txt`: install Flask, Elasticsearch tooling, Google API clients, and dotenv support.
+- `python -m python_app.transcript_collector --channel UC... --output data/raw`: fetch transcript JSON for a channel; rerun to refresh cached data.
+- `python -m python_app.ingest --source data/video_metadata --index this_little_corner_py`: index prepared metadata and auto-create mappings when needed.
+- `python -m python_app.search_app`: launch the Flask server on port 8080 for UI smoke tests.
+
+## Coding Style & Naming Conventions
+- Follow PEP 8 with 4-space indentation, `snake_case` for functions/modules, and `CamelCase` for classes; reserve UPPER_SNAKE_CASE for configuration constants.
+- Keep Elasticsearch payload keys lower-case with underscores, and centralize shared values in `config.py` rather than scattering literals.
+
+## Testing Guidelines
+- No automated suite is committed yet; when adding coverage, create `tests/` modules using `pytest` with files named `test_*.py`.
+- Focus tests on collector pagination, ingest transformations, and Flask route helpers, and run `python -m pytest` locally before opening a PR.
+- Manually verify by ingesting a small sample into a local Elasticsearch node and checking facets, highlights, and transcript retrieval via the UI.
+
+## Commit & Pull Request Guidelines
+- Mirror the existing history: short, imperative commit subjects (e.g. “Fix results overflow”, “Add video reference tracking”).
+- PRs should describe scope, list environment variables or indices touched, link issues, and attach before/after screenshots whenever UI output changes. Highlight Elasticsearch mapping or data migration impacts for both search and frontend reviewers.
+
+## Configuration & Security Tips
+- Load credentials through environment variables (`ELASTIC_URL`, `ELASTIC_USERNAME`, `ELASTIC_PASSWORD`, `ELASTIC_API_KEY`, `YOUTUBE_API_KEY`) or a `.env` file, and keep secrets out of version control.
+- Adjust `ELASTIC_VERIFY_CERTS`, `ELASTIC_CA_CERT`, and `ELASTIC_DEBUG` only while debugging, and prefer branch-specific indices (`this_little_corner_py_<initials>`) to avoid clobbering shared data.

+# TLC Search + Feed Master Integration
+
+This directory contains an integrated setup combining:
+- **TLC Search**: Flask app for searching YouTube transcripts (Elasticsearch/Qdrant)
+- **Feed Master**: RSS aggregator for YouTube channels
+- **RSS Bridge**: Converts YouTube channels to RSS feeds
+
+All services share the same source of truth for YouTube channels from `channels.yml` and the adjacent
+`urls.txt` in this repository.
+
+## Architecture
+
+```

+```
+
+## Services
+
+### 1. TLC Search (Port 8080)
+- Indexes and searches YouTube transcripts
+- Uses Elasticsearch for metadata and Qdrant for vector search
+- Connects to remote Elasticsearch/Qdrant instances
+
+### 2. RSS Bridge (Port 3001)
+- Converts YouTube channels to RSS feeds
+- Supports both channel IDs and @handles
+- Used by Feed Master to aggregate feeds
+
+### 3. Feed Master (Port 8097)
+- Aggregates all YouTube channel RSS feeds into one unified feed
+- Updates every 5 minutes
+- Keeps the most recent 200 items from all channels
+
+## Setup
+
+### Prerequisites
+- Docker and Docker Compose
+- Python 3.x
+
+### Configuration
+
+1. **Environment Variables**: Create `.env` file with:
+```bash
+# Elasticsearch
+ELASTIC_URL=https://your-elasticsearch-url
+ELASTIC_INDEX=this_little_corner_py
+ELASTIC_USERNAME=your_username
+ELASTIC_PASSWORD=your_password
+
+# Qdrant
+QDRANT_URL=https://your-qdrant-url
+QDRANT_COLLECTION=tlc-captions-full
+
+# Optional UI links
+RSS_FEED_URL=/rss/youtube-unified
+CHANNELS_PATH=/app/python_app/channels.yml
+RSS_FEED_UPSTREAM=http://feed-master:8080
+```
+
+2. **Generate Feed Configuration**:
+```bash
+# Regenerate feed-master config from the channels list
+python3 -m python_app.generate_feed_config_simple
+```
+
+This reads `channels.yml` and generates `feed-master-config/fm.yml`.
+
+### Starting Services
+
+```bash
+# Start all services
+docker compose up -d
+
+# View logs
+docker compose logs -f
+
+# View specific service logs
+docker compose logs -f feed-master
+docker compose logs -f rss-bridge
+docker compose logs -f app
+```
+
+### Stopping Services
+
+```bash
+# Stop all services
+docker compose down
+
+# Stop specific service
+docker compose stop feed-master
+```
+
+## Usage
+
+### Unified RSS Feed
+Access the aggregated feed through the TLC app (recommended):
+- **URL**: http://localhost:8080/rss
+- **Format**: RSS/Atom XML
+- **Behavior**: Filters RSS-Bridge error items and prefixes titles with channel name
+- **Updates**: Every 5 minutes (feed-master schedule)
+- **Items**: Most recent 200 items across all channels
+
+Direct feed-master access still works:
+- **URL**: http://localhost:8097/rss/youtube-unified
+
+### TLC Search
+Access the search interface at:
+- **URL**: http://localhost:8080
+
+### Channel List Endpoints
+- **Plain text list**: http://localhost:8080/channels.txt
+- **JSON metadata**: http://localhost:8080/api/channel-list
+
+### RSS Bridge
+Access individual channel feeds or the web interface at:
+- **URL**: http://localhost:3001
+
+## Updating Channel List
+
+When channels are added/removed from `channels.yml`:
+
+```bash
+# 1. Regenerate feed configuration
+cd /var/core/this-little-corner/src/python_app
+    python3 -m python_app.generate_feed_config_simple
+
+# 2. Restart feed-master to pick up changes
+docker compose restart feed-master
+```
+
+## File Structure
+
+```
+python_app/
+├── docker-compose.yml              # All services configuration
+├── channels.yml                    # Canonical YouTube channel list
+├── urls.txt                        # URL list kept in sync with channels.yml

+└── README-FEED-MASTER.md          # This file
+```
+
+## Troubleshooting
+
+### Feed Master not updating
+```bash
+# Check if RSS Bridge is accessible
+curl http://localhost:3001
+
+# Restart both services in order
+docker compose restart rss-bridge
+sleep 10
+docker compose restart feed-master
+```
+
+### Configuration issues
+```bash
+# Regenerate configuration
+python -m python_app.generate_feed_config_simple
+
+# Validate the YAML
+cat feed-master-config/fm.yml
+
+# Restart feed-master
+docker compose restart feed-master
+```
+
+### View feed-master logs
+```bash
+docker compose logs -f feed-master | grep -E "(ERROR|WARN|youtube)"
+```
+
+## Integration Notes
+
+- **Single Source of Truth**: All channel URLs come from `channels.yml` and `urls.txt` in this repo
+- **Automatic Regeneration**: Run `python3 -m python_app.generate_feed_config_simple` when `channels.yml` changes
+- **No Manual Editing**: Don't edit `fm.yml` directly - regenerate it from the script
+- **Handle Support**: Supports both `/channel/ID` and `/@handle` URL formats
+- **Shared Channels**: Same channels used for transcript indexing (TLC Search) and RSS aggregation (Feed Master)
+- **Skip Broken RSS**: Set `rss: false` in `channels.yml` to exclude a channel from RSS aggregation
+
+## Future Enhancements
+
+- [ ] Automated config regeneration on git pull
+- [ ] Channel name lookup from YouTube API
+- [ ] Integration with TLC Search for unified UI
+- [ ] Webhook notifications for new videos
+- [ ] OPML export for other RSS readers

@@ -85,3 +85,34 @@ Visit <http://localhost:8080/> and you’ll see a barebones UI that:

 Feel free to expand on this scaffold—add proper logging, schedule transcript
 updates, or flesh out the UI—once you’re happy with the baseline behaviour.
+
+## Run with Docker Compose (App Only; Remote ES/Qdrant)
+
+The provided compose file builds/runs only the Flask app and expects **remote** Elasticsearch/Qdrant endpoints. Supply them via environment variables (directly or a `.env` alongside `docker-compose.yml`):
+
+```bash
+ELASTIC_URL=https://your-es-host:9200 \
+QDRANT_URL=https://your-qdrant-host:6333 \
+docker compose up --build
+```
+
+Other tunables (defaults shown in compose):
+- `ELASTIC_INDEX` (default `this_little_corner_py`)
+- `ELASTIC_USERNAME` / `ELASTIC_PASSWORD` or `ELASTIC_API_KEY`
+- `ELASTIC_VERIFY_CERTS` (set to `1` for real TLS verification)
+- `QDRANT_COLLECTION` (default `tlc-captions-full`)
+- `QDRANT_VECTOR_NAME` / `QDRANT_VECTOR_SIZE` / `QDRANT_EMBED_MODEL`
+- `RATE_LIMIT_ENABLED` (default `1`)
+- `RATE_LIMIT_REQUESTS` (default `60`)
+- `RATE_LIMIT_WINDOW_SECONDS` (default `60`)
+
+Port 8080 on the host is forwarded to the app. Mount `./data` (read-only) if you want local fallbacks for metrics (`LOCAL_DATA_DIR=/app/data/video_metadata`); otherwise the app will rely purely on the remote backends. Stop the container with `docker compose down`.
+
+## CI (Docker build)
+
+A Gitea Actions workflow (`.gitea/workflows/docker-build.yml`) builds and pushes the Docker image on every push to `master`. Configure the following repository secrets in Gitea:
+
+- `DOCKER_USERNAME`
+- `DOCKER_PASSWORD`
+
+The image is tagged as `gitea.ghost.tel/knight/tlc-search:latest` and with the commit SHA. Adjust `IMAGE_NAME` in the workflow if you need a different registry/repo.

knight	2846e13a81	Fix timestamp parsing for string format timestamps Both primary and secondary transcripts use 'timestamp' field with string format "HH:MM:SS.mmm" instead of numeric seconds. Changes: - Add parseTimestampToSeconds() to handle string timestamps - Parse "HH:MM:SS.mmm" format (e.g., "00:00:39.480") - Also handle "MM:SS" format - Still support numeric timestamps (seconds or milliseconds) - Check 'timestamp' field first (primary format in data) This fixes the NaN issue and displays correct timestamps for both primary and secondary transcripts. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-05 01:16:26 -05:00
knight	e241d206c5	Fix NaN timestamps with proper type checking Previous \|\| chain could pass through invalid values causing NaN. Now explicitly checks each possible timestamp field with: - null check (field != null) - NaN check (!isNaN(parseFloat(field))) - Takes first valid numeric value found This ensures timestamps always have a valid number, defaulting to 0 if no valid timestamp field is found. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-11-05 01:09:21 -05:00
