The goal of this refactor was simple: views, models, admin actions, commands, and services should each do one kind of work.

Main changes

1. Digest removed

• Removed Digest code, routes, admin entry points, scheduled tasks, and related documentation
• Kept cleanup logic for old Digest-generated data

2. Feed workflow unified

• Single-feed update workflow moved to core/services/feed/pipeline.py
• Post-update refresh logic moved to core/services/feed/refresh.py

3. Output and filtering unified

• Feed rendering moved to core/services/feed/rendering.py
• RSS/JSON response wrapping moved to core/services/feed/response.py
• Feed and tag filtering rules moved to core/services/feed/filters.py

4. Admin actions unified

• Force update and tag recombination moved to core/services/admin/actions.py
• Batch modification moved to core/services/admin/batch.py

5. Agent execution logic extracted

• OpenAI / DeepL / LibreTranslate / TestAgent execution logic moved to core/services/agent/
• core/models/agent.py now mainly keeps fields and thin wrappers

6. Prompt defaults extracted

• Default prompts moved to core/prompts.py
• config/settings.py now keeps configuration plus compatibility exports

Current maintenance entry points

If you need to change something later:

• Feed update flow: core/services/feed/pipeline.py
• Refresh and cache behavior: core/services/feed/refresh.py
• Output generation: core/services/feed/rendering.py and response.py
• Filtering rules: core/services/feed/filters.py
• Admin actions: core/services/admin/
• OPML: core/services/opml.py
• Agent behavior: core/services/agent/

Rules to keep

1. Views and commands stay as entry points only
2. Models keep data and minimal behavior; complex logic belongs in services
3. Rules of the same kind should live in one place only
4. New behavior should add tests first, then service-layer implementation
