## Compatibility Audit

### Hard compatibility checks
1. Node 24 vs Vite 8: compatible (Vite requires Node 20.19+ or 22.12+).
2. React 19.2.x vs MUI 9: compatible (MUI supports React ^17 || ^18 || ^19).
3. React 19.2.x vs react-dom 19.2.5: compatible (same major/minor line).
4. TypeScript 6 vs MUI 9: compatible (MUI requires TS >=4.9).
5. Node 24 vs Express 5.2.1: compatible (Express requires Node >=18).
6. Apple container vs Dockerfile workflow: compatible (container build supports Dockerfile and Containerfile).

### Environment-specific incompatibilities / risks
1. Docker command compatibility: incompatible by environment constraint.
   - Any script that assumes docker build/run must be translated to container build/run.
2. Apple container stability: medium risk.
   - Project is pre-1.0 and may introduce breaking changes in minor releases.
   - Mitigation: pin CLI release during execution and document upgrade policy.
3. Slim Debian runtime package availability: low-to-medium operational risk.
   - trixie-slim is smaller than full images and may omit convenience packages.
   - Mitigation: install only required OS packages explicitly and validate build/runtime dependencies.
4. @mui/mcp@latest floating version: reproducibility risk.
   - Mitigation: pin exact MCP package version for CI/repeatable local behavior once selected.

### Migration-policy compatibility with user constraints
1. Latest stable React only: satisfied by React 19.2.x.
2. No legacy/migration support tracks: satisfied; no React 18 fallback assumptions included.
3. MUI usage policy: satisfied with plain Material UI v9.x.x and mui-mcp-first guidance.
