The AIRIS MCP Gateway installer downloads a docker-compose.yml from a raw GitHub URL and immediately executes it via docker compose up with no integrity verification. If the upstream repo is compromised, arbitrary containers run on the user's machine with host filesystem access. This change: - Adds SHA-256 hash verification after downloading docker-compose.dist.yml - Aborts installation and deletes the file if the hash doesn't match - Prints expected vs actual hash for debugging The hash must be updated when the upstream docker-compose.dist.yml is intentionally changed. Fixes #537 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Adds SHA-256 hash verification for the docker-compose.dist.yml file downloaded during AIRIS MCP Gateway installation, preventing execution of tampered compose files.
Fixes #537
Problem
The installer downloads
docker-compose.dist.ymlfrom a raw GitHub URL and immediately runsdocker compose up -d— with no checksum, no signature, and no pinned commit. If the upstream repo is compromised, arbitrary containers execute on the user's machine with host filesystem access (via${PWD}read-write mounts).Changes
