## Purpose

Canonical specification for news-aggregator requirements synced from OpenSpec change deltas.

## Requirements

### Requirement: News aggregation via Perplexity API
The system SHALL fetch AI news hourly from Perplexity API and store it with full attribution.

#### Scenario: Hourly news fetch
- **WHEN** the scheduled job runs every hour
- **THEN** the system calls Perplexity API with query "latest AI news"
- **AND** stores the response with headline, summary, source URL, and timestamp

#### Scenario: API error handling
- **WHEN** Perplexity API returns an error or timeout
- **THEN** the system logs the error with cost tracking
- **AND** retries with exponential backoff up to 3 times
- **AND** falls back to OpenRouter API if `OPENROUTER_API_KEY` is configured
- **AND** continues using cached content if all retries and fallback fail

### Requirement: Featured image generation
The system SHALL generate or fetch a relevant featured image for each news item.

#### Scenario: Image acquisition
- **WHEN** a new news item is fetched
- **THEN** the system SHALL request a relevant image URL from Perplexity
- **AND** download and optimize the image locally using Pillow
- **AND** apply quality compression based on `IMAGE_QUALITY` env var (1-100, default 85)
- **AND** store the optimized image path and original image credit/source information

#### Scenario: Image optimization configuration
- **WHEN** the system processes an image
- **THEN** it SHALL read `IMAGE_QUALITY` from environment (default: 85)
- **AND** apply JPEG compression at specified quality level
- **AND** resize images exceeding 1200px width while maintaining aspect ratio
- **AND** store optimized images in `/app/static/images/` directory

#### Scenario: Image fallback
- **WHEN** image generation fails or returns no result
- **THEN** the system SHALL use a default ClawFort branded placeholder image

### Requirement: News data persistence with retention
The system SHALL store news items for exactly 30 days with automatic archiving.

#### Scenario: News storage
- **WHEN** a news item is fetched from Perplexity
- **THEN** the system SHALL store it in SQLite with fields: id, headline, summary, source_url, image_url, image_credit, published_at, created_at
- **AND** set archived=false by default

#### Scenario: Automatic archiving
- **WHEN** a nightly cleanup job runs
- **THEN** the system SHALL mark all news items older than 30 days as archived=true
- **AND** delete archived items older than 60 days permanently

#### Scenario: Duplicate prevention
- **WHEN** fetching news that matches an existing headline (within 24 hours)
- **THEN** the system SHALL skip insertion to prevent duplicates
