+
+This file provides guidance to Claude Code (claude.ai/code) when working with
+code in this repository.
+
+## Project Overview
+
+ClusterCockpit is a job-specific performance monitoring framework for HPC
+clusters. This is a Golang backend that provides REST and GraphQL APIs, serves a
+Svelte-based frontend, and manages job archives and metric data from various
+time-series databases.
+
+## Build and Development Commands
+
+### Building
+
+```bash
+# Build everything (frontend + backend)
+make
+
+# Build only the frontend
+make frontend
+
+# Build only the backend (requires frontend to be built first)
+go build -ldflags='-s -X main.date=$(date +"%Y-%m-%d:T%H:%M:%S") -X main.version=1.4.4 -X main.commit=$(git rev-parse --short HEAD)' ./cmd/cc-backend
+```
+
+### Testing
+
+```bash
+# Run all tests
+make test
+
+# Run tests with verbose output
+go test -v ./...
+
+# Run tests for a specific package
+go test ./internal/repository
+```
+
+### Code Generation
+
+```bash
+# Regenerate GraphQL schema and resolvers (after modifying api/*.graphqls)
+make graphql
+
+# Regenerate Swagger/OpenAPI docs (after modifying API comments)
+make swagger
+```
+
+### Frontend Development
+
+```bash
+cd web/frontend
+
+# Install dependencies
+npm install
+
+# Build for production
+npm run build
+
+# Development mode with watch
+npm run dev
+```
+
+### Running
+
+```bash
+# Initialize database and create admin user
+./cc-backend -init-db -add-user demo:admin:demo
+
+# Start server in development mode (enables GraphQL Playground and Swagger UI)
+./cc-backend -server -dev -loglevel info
+
+# Start demo with sample data
+./startDemo.sh
+```
+
+## Architecture
+
+### Backend Structure
+
+The backend follows a layered architecture with clear separation of concerns:
+
+- **cmd/cc-backend**: Entry point, orchestrates initialization of all subsystems
+- **internal/repository**: Data access layer using repository pattern
+  - Abstracts database operations (SQLite3 only)
+  - Implements LRU caching for performance
+  - Provides repositories for Job, User, Node, and Tag entities
+  - Transaction support for batch operations
+- **internal/api**: REST API endpoints (Swagger/OpenAPI documented)
+- **internal/graph**: GraphQL API (uses gqlgen)
+  - Schema in `api/*.graphqls`
+  - Generated code in `internal/graph/generated/`
+  - Resolvers in `internal/graph/schema.resolvers.go`
+- **internal/auth**: Authentication layer
+  - Supports local accounts, LDAP, OIDC, and JWT tokens
+  - Implements rate limiting for login attempts
+- **internal/metricdata**: Metric data repository abstraction
+  - Pluggable backends: cc-metric-store, Prometheus, InfluxDB
+  - Each cluster can have a different metric data backend
+- **internal/archiver**: Job archiving to file-based archive
+- **pkg/archive**: Job archive backend implementations
+  - File system backend (default)
+  - S3 backend
+  - SQLite backend (experimental)
+- **pkg/nats**: NATS integration for metric ingestion
+
+### Frontend Structure
+
+- **web/frontend**: Svelte 5 application
+  - Uses Rollup for building
+  - Components organized by feature (analysis, job, user, etc.)
+  - GraphQL client using @urql/svelte
+  - Bootstrap 5 + SvelteStrap for UI
+  - uPlot for time-series visualization
+- **web/templates**: Server-side Go templates
+
+### Key Concepts
+
+**Job Archive**: Completed jobs are stored in a file-based archive following the
+[ClusterCockpit job-archive
+specification](https://github.com/ClusterCockpit/cc-specifications/tree/master/job-archive).
+Each job has a `meta.json` file with metadata and metric data files.
+
+**Metric Data Repositories**: Time-series metric data is stored separately from
+job metadata. The system supports multiple backends (cc-metric-store is
+recommended). Configuration is per-cluster in `config.json`.
+
+**Authentication Flow**:
+
+1. Multiple authenticators can be configured (local, LDAP, OIDC, JWT)
+2. Each authenticator's `CanLogin` method is called to determine if it should handle the request
+3. The first authenticator that returns true performs the actual `Login`
+4. JWT tokens are used for API authentication
+
+**Database Migrations**: SQL migrations in `internal/repository/migrations/` are
+applied automatically on startup. Version tracking in `version` table.
+
+**Scopes**: Metrics can be collected at different scopes:
+
+- Node scope (always available)
+- Core scope (for jobs with ≤8 nodes)
+- Accelerator scope (for GPU/accelerator metrics)
+
+## Configuration
+
+- **config.json**: Main configuration (clusters, metric repositories, archive settings)
+- **.env**: Environment variables (secrets like JWT keys)
+  - Copy from `configs/env-template.txt`
+  - NEVER commit this file
+- **cluster.json**: Cluster topology and metric definitions (loaded from archive or config)
+
+## Database
+
+- Default: SQLite 3 (`./var/job.db`)
+- Connection managed by `internal/repository`
+- Schema version in `internal/repository/migration.go`
+
+## Code Generation
+
+**GraphQL** (gqlgen):
+
+- Schema: `api/*.graphqls`
+- Config: `gqlgen.yml`
+- Generated code: `internal/graph/generated/`
+- Custom resolvers: `internal/graph/schema.resolvers.go`
+- Run `make graphql` after schema changes
+
+**Swagger/OpenAPI**:
+
+- Annotations in `internal/api/*.go`
+- Generated docs: `api/docs.go`, `api/swagger.yaml`
+- Run `make swagger` after API changes
+
+## Testing Conventions
+
+- Test files use `_test.go` suffix
+- Test data in `testdata/` subdirectories
+- Repository tests use in-memory SQLite
+- API tests use httptest
+
+## Common Workflows
+
+### Adding a new GraphQL field
+
+1. Edit schema in `api/*.graphqls`
+2. Run `make graphql`
+3. Implement resolver in `internal/graph/schema.resolvers.go`
+
+### Adding a new REST endpoint
+
+1. Add handler in `internal/api/*.go`
+2. Add route in `internal/api/rest.go`
+3. Add Swagger annotations
+4. Run `make swagger`
+
+### Adding a new metric data backend
+
+1. Implement `MetricDataRepository` interface in `internal/metricdata/`
+2. Register in `metricdata.Init()` switch statement
+3. Update config.json schema documentation
+
+### Modifying database schema
+
+1. Create new migration in `internal/repository/migrations/`
+2. Increment `repository.Version`
+3. Test with fresh database and existing database
+
+## Dependencies
+
+- Go 1.24.0+ (check go.mod for exact version)
+- Node.js (for frontend builds)
+- SQLite 3 (only supported database)
+- Optional: NATS server for metric ingestion
