+## Context
+
+RTLSDR-Airband records CB transmissions as MP3 files into `/home/m/recordings/` on the Pi, organized by channel subdirectories with dated subdirectories inside. The recorder runs as a Docker container via `docker-compose.yml`.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Serve the recordings directory over HTTP with browsable directory listings
+- Allow MP3 playback via the browser's native audio handling
+- Deploy as a Docker container alongside the existing `sdr-recorder` service
+
+**Non-Goals:**
+- Custom web UI, styling, or JavaScript
+- Authentication (local network only)
+- Modifying, uploading, or deleting recordings
+- Live streaming or transcription
+
+## Decisions
+
+### Use Nginx with HTML autoindex, no custom frontend
+
+**Decision**: Use `nginx:alpine` with `autoindex on` to serve the recordings directory. No custom HTML, JS, or CSS.
+
+**Rationale**: Nginx's built-in directory listing is fully functional for browsing channel/date directories. Modern browsers play MP3 files natively when clicked. This requires only an Nginx config file and a docker-compose service — zero application code.
+
+**Alternatives considered**:
+- **Custom SPA frontend**: Adds complexity (build tools, JS code) for marginal UX improvement over native directory listing.
+- **Python http.server**: Simpler but less performant and no Alpine image parity.
+
+## Risks / Trade-offs
+
+- **[No search or filtering]** → Users browse by directory structure. Acceptable given the channel/date organization.
+- **[Plain directory listing]** → No styled UI. Acceptable for a local utility tool.
+- **[No auth]** → Anyone on the LAN can access. Acceptable per non-goals.

+## Why
+
+Recordings from the RTLSDR-Airband CB scanner are stored as MP3 files on the Pi's filesystem (`/home/m/recordings/`), organized by channel and date. There's currently no way to browse or listen to them without SSH access. A web server with directory listing would make recordings browsable and playable from any device on the local network.
+
+## What Changes
+
+- Add an Nginx container to `docker-compose.yml` that serves the recordings directory with autoindex enabled
+- Users browse directories and click MP3 files to play them natively in the browser
+
+## Capabilities
+
+### New Capabilities
+- `recording-browser`: Nginx autoindex serving the recordings directory over HTTP, with browser-native MP3 playback
+
+### Modified Capabilities
+
+_(none)_
+
+## Impact
+
+- **Docker deployment**: New Nginx service added to `docker-compose.yml`, sharing the `/home/m/recordings` volume (read-only)
+- **Pi resources**: Negligible — Nginx Alpine uses ~2MB RAM
+- **Network**: Exposes HTTP port on the Pi's local network

+## ADDED Requirements
+
+### Requirement: Serve recordings directory over HTTP
+The system SHALL serve the contents of the recordings directory via an Nginx web server with directory listing enabled.
+
+#### Scenario: Browse channel directories
+- **WHEN** a user navigates to the root URL of the web server
+- **THEN** the server displays a directory listing showing the channel subdirectories
+
+#### Scenario: Browse date directories within a channel
+- **WHEN** a user clicks a channel directory
+- **THEN** the server displays a directory listing of date subdirectories for that channel
+
+#### Scenario: Browse recording files within a date
+- **WHEN** a user clicks a date directory
+- **THEN** the server displays a listing of MP3 recording files
+
+### Requirement: Browser-native MP3 playback
+The system SHALL serve MP3 files with correct MIME type so browsers can play them natively.
+
+#### Scenario: Play a recording
+- **WHEN** a user clicks an MP3 file link in the directory listing
+- **THEN** the browser opens and plays the MP3 file using its native audio player
+
+### Requirement: Docker deployment
+The web server SHALL run as a Docker container defined in `docker-compose.yml`, mounting the recordings directory read-only.
+
+#### Scenario: Start alongside recorder
+- **WHEN** a user runs `docker compose up` on the Pi
+- **THEN** the Nginx service starts alongside the `sdr-recorder` service and is accessible via HTTP
+
+#### Scenario: Read-only access to recordings
+- **WHEN** the Nginx container accesses the recordings volume
+- **THEN** the volume is mounted read-only, preventing modification of recording files

+## 1. Nginx Configuration
+
+- [x] 1.1 Create `nginx.conf` with a server block that serves `/recordings` with `autoindex on` and correct MIME type for MP3 files
+
+## 2. Docker Integration
+
+- [x] 2.1 Add an `nginx` service to `docker-compose.yml` using `nginx:alpine`, mounting `/home/m/recordings` to `/recordings:ro` and `./nginx.conf` to the Nginx config path, exposing port 8080
+
+## 3. Deploy and Verify
+
+- [x] 3.1 Deploy to the Pi and verify directory browsing and MP3 playback work at `http://sdr-pi:8080`
