- Run all local engines in parallel using goroutines + sync.WaitGroup
- Individual engine failures are captured as unresponsive_engines entries
instead of aborting the entire search request
- Context cancellation is respected: cancelled engines report as unresponsive
- Upstream proxy failure is also gracefully handled (single unresponsive entry)
- Extract unresponsiveResponse() and emptyResponse() helpers for consistency
- Add comprehensive tests:
- ConcurrentEngines: verifies parallelism (2x100ms engines complete in ~100ms)
- GracefulDegradation: one engine fails, one succeeds, both represented
- AllEnginesFail: no error returned, all engines in unresponsive_engines
- ContextCancellation: engine respects context timeout, reports unresponsive
- Add internal/config package with TOML parsing (BurntSushi/toml)
- Create config.example.toml documenting all settings
- Update main.go to load config via -config flag (default: config.toml)
- Environment variables remain as fallback overrides for backward compat
- Config file values are used as defaults; env vars override when set
- Add comprehensive tests for file loading, defaults, and env overrides
- Add config.toml to .gitignore (secrets stay local)
Implement an API-first Go rewrite with local engine adapters, upstream fallback, and Nix-based tooling so searches can run without matching the original UI while preserving response compatibility.
