Summary

Introduce a fixtures system for providing cached data (e.g., headlines) to avoid network dependencies during development and testing.

Features

  • New engine/fixtures/headlines.json containing cached headline data
  • Support for source="fixture" in PipelinePreset
  • fetch.py cache path moved to engine/fixtures/headlines.json
  • Updated fixtures loading logic in both preset-based and direct CLI modes

Why

  • Faster development: no network fetch needed
  • Reliable testing: deterministic data without external dependencies
  • Offline capability: work without internet access

Files Changed

  • engine/fetch.py (cache path update)
  • engine/fixtures/headlines.json (new, sample headline dataset)
  • engine/pipeline/presets.py (add FIXTURE_PRESET)
  • engine/app.py (fixture source handling)

Status

Feature complete.

Related

  • Works with direct CLI mode validation (#29)
  • Supports pipeline introspection and development demos
