+- [x] 01-01: Nix flake, process-compose, setup script, .gitignore
-- [ ] 01-02-PLAN.md — Run setup, create plugin scaffold, verify end-to-end

 ### Phase 2: Plugin Scaffold + Data Layer
 **Goal**: Plugin is recognized by Kimai, shows a widget on the dashboard, and serves aggregated daily time data via API

+# Plan 01-01: Nix Flake and Dev Infrastructure Summary
+
+**Nix devshell with PHP 8.2, MariaDB 11.4, Node 22, process-compose orchestration, and Kimai bootstrap script**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-04-08T09:10:30Z
+- **Completed:** 2026-04-08T09:12:45Z
+- **Tasks:** 2
+- **Files modified:** 5
+
+## Accomplishments
+- Nix flake providing PHP 8.2.30, Composer 2.9.5, Node 22.22.2, MariaDB 11.4.9, symfony-cli 5.16.1, process-compose 1.94.0
+- process-compose config with MariaDB health checks and Kimai server dependency ordering
+- Idempotent setup script that clones Kimai 2.52.0, installs deps, seeds data, and symlinks the plugin
+
+## Task Commits
+
+1. **Task 1: Create Nix flake with devshell** - `cc5a25e` (feat)
+2. **Task 2: Create process-compose config and setup script** - `b20e61e` (feat)
+
+## Files Created/Modified
+- `flake.nix` - Nix devshell with all required packages and PHP extensions
+- `flake.lock` - Pinned nixpkgs input
+- `.envrc` - direnv integration (use flake)
+- `.gitignore` - Excludes dev artifacts, node_modules, vendor, .direnv
+- `dev/process-compose.yaml` - MariaDB + Kimai process definitions with health checks
+- `dev/setup.sh` - One-time Kimai bootstrap (clone, install, seed, symlink)
+
+## Decisions Made
+- Used x86_64-linux only instead of eachDefaultSystem -- this is a NixOS-only project
+- MariaDB binds to 127.0.0.1:3307 with skip-grant-tables for frictionless local dev
+- Kimai dev server on port 8010 to avoid conflicts
+- ServerVersion in DATABASE_URL set to 11.4.9-MariaDB matching actual installed version
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+None.
+
+## User Setup Required
+None - no external service configuration required.
+
+## Next Phase Readiness
+- Dev tooling is ready; Plan 01-02 can proceed to run setup.sh and verify plugin scaffold
+- All tools verified working via `nix develop`
