- Multi-stage Docker build: Dockerfile compiles frontend (Node.js) and backend (Gradle) inside Docker; no local Java/Node.js required - Security hardening: replaced full host root mount with specific directory mounts (/proc, /sys, /etc, /var, /home, /opt, /tmp, /srv, /usr) - Host metrics consistency: LinuxMemoryService and CpuDetailsService now read from /host/proc instead of container OSHI - Concurrency: replaced synchronized with AtomicReference in 3 services - Global error handling: added @RestControllerAdvice for JSON error responses - Unit tests: added 32 tests for /proc parsers, CPU usage, process uptime - Docker security: non-root user, read-only FS, no-new-privileges, healthcheck - Debug logging: added log.debug() in silent catch blocks - Documentation: updated README, INSTALLATION, DEVELOPMENT, CONFIGURATION, ARCHITECTURE, CHANGELOG Co-authored-by: Junie <junie@jetbrains.com>

## Unreleased
|
|
|
|
- **Multi-stage Docker build** — the Dockerfile now compiles both the Angular frontend and Spring Boot backend inside Docker using three stages (Node.js → Gradle → JRE). Build the entire application with a single `docker build` command — no local Java or Node.js required.
|
|
- **Security hardening** — replaced full host root mount (`/:/host/root:ro`) with specific directory mounts (`/proc`, `/sys`, `/etc/hostname`, `/etc/os-release`, `/var`, `/home`, `/opt`, `/tmp`, `/srv`, `/usr`) to minimize the attack surface.
|
|
- **Host metrics consistency** — `LinuxMemoryService` and `CpuDetailsService` now read host metrics from `/host/proc` instead of container metrics from OSHI.
|
|
- **Concurrency improvements** — replaced `synchronized` methods with `AtomicReference` in `SystemMetricsService`, `SystemProcessesService`, and `CpuDetailsService` to eliminate lock contention.
|
|
- **Global error handling** — added `@RestControllerAdvice` for structured JSON error responses.
|
|
- **Unit tests** — added 32 tests covering `/proc` file parsers, CPU usage calculations, and process uptime logic.
|
|
- **Docker security** — added non-root user (`appuser`), read-only filesystem, `no-new-privileges`, and healthcheck to the container.
|
|
- **Debug logging** — added `log.debug()` calls in silent catch blocks across all services.
|
|
- **Documentation structure established.**
