Realm

🌌 A reproducible developer workstation and self-hosted runtime foundation for projects and organizations.

Realm describes environments as versioned capabilities and composable profiles. One resolved profile can feed several projections—Docker images, Dev Containers, Nix, or Linux workstation setup—without turning a Dockerfile into the source of truth.

Contract preview

• catalog/capabilities.json defines packages, artifacts, dependencies, platforms, projections, and safety constraints.
• catalog/tool-evaluations.json is the curated admission queue for tools before they become stable profile capabilities.
• profiles/ defines base, language variants, full, and an explicit services boundary.
• schemas/ publishes the v1 catalog, profile, resolved-profile, and tool-evaluation contracts.
• tools/realm_profiles.py validates and resolves the environment model without third-party dependencies.
• tools/realm_tool_registry.py validates tool inclusion decisions and renders the review queue.
• docs/profiles.md records profile semantics and release boundaries.
• docs/tool-registry.md documents tool evaluation, stable-inclusion gates, overlap decisions, and maintenance policy.
• docs/mantle-shell.md explains build-time SHELL versus an installed interactive Mantle shell.

Validate the contracts and resolve the full Docker projection:

python3 tools/realm_profiles.py validate-catalog
python3 tools/realm_profiles.py validate-profiles
python3 tools/realm_tool_registry.py validate
python3 tools/realm_profiles.py resolve \
  --profile "full" \
  --platform "linux/amd64" \
  --projection "docker" \
  --output "/tmp/realm-full.json"
python3 -m unittest discover --start-directory tests --verbose

Render the current tool review queue:

python3 tools/realm_tool_registry.py report

This contract intentionally precedes image generation. A tool must pass the curated inclusion gates before stable profile admission. Published images must be rendered from a resolved profile, built for supported platforms, tested, and then referenced by immutable digest.
