Port conflict validation:
- api/port_registry.py: detect_conflicts() checks all service sections for shared port values
- api/app.py: returns HTTP 409 on port conflict after existing range validation
- webui/src/pages/Settings.jsx: JS-side detectPortConflicts() with useMemo shows inline
conflict errors and blocks Save before the request is made; catch blocks surface server
error messages (including 409) instead of generic fallbacks
Config autosave on Apply:
- webui/src/contexts/DraftConfigContext.jsx: new context; Settings registers flush callbacks
per section; App calls flushAll() before applyPending() when any section is dirty
- webui/src/App.jsx: wraps tree with DraftConfigProvider, handleApply shows 'saving' banner
state and awaits flushAll()
- webui/src/pages/Settings.jsx: registers identity + per-service flushers; propagates dirty
state into context via setDirty; uses refs to avoid stale closures
Extended integration test coverage (114 new tests):
- tests/integration/test_config_api.py: GET/PUT config, export, import, backup lifecycle
- tests/integration/test_network_services.py: DNS records + DHCP reservations CRUD
- tests/integration/test_containers.py: list, restart, logs, stats; recovery polling
- tests/integration/test_negative_scenarios.py: error-path coverage for all endpoints
- tests/test_port_conflicts.py: 20 unit tests for port_registry.detect_conflicts()
Pre-commit hook updated to skip tests/integration/ (live-stack tests require a running
stack and must be run explicitly via `make test-integration`).
