## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:

- [Roadmap]: TDD approach -- tests written alongside features, not in a separate phase
- [Roadmap]: Nix dev environment is Phase 1 prerequisite; everything else depends on it
- [Research]: Use Vitest + jsdom for JS tests (d3 v7 is ESM-only, Jest struggles)
- [Research]: Ship prebuilt JS in Resources/public/, do not hook into Kimai's Webpack Encore
- [Phase 1]: x86_64-linux only for Nix flake (NixOS-only project)
- [Phase 1]: MariaDB 11.4.9 on port 3307, Kimai on port 8010
- [Phase 1]: Plugin needs DI extension + services.yaml to register as tagged PluginInterface service
- [Phase 1]: Kimai's autoloader needs exclude-from-classmap for recursive plugin symlink
- [Phase 1]: PHP memory_limit=1G required for Kimai cache warmup
- [Phase 1]: process-compose API server disabled (-p 0) to avoid port 8080 conflict
- [Phase 2]: Removed final from HeatmapService to allow PHPUnit mocking
- [Phase 03]: IIFE format with KimaiHeatmap global for browser compat
- [Phase 03]: kimai.initialized event for deferred widget init, javascriptRequest fallback for AJAX
- [Phase 04]: Render project filter only when user has tracked projects

### Pending Todos

None yet.

### Blockers/Concerns

- [Research]: Kimai widget API (WidgetInterface, DI tags) needs verification against target Kimai version
