Nix/devenv Compatibility Report

basectl devenv-report [project] reads a Base project manifest and reports how its fields map to a possible Nix/devenv setup. It does not generate Nix files, invoke Nix, install packages, or execute project commands.

basectl devenv-report demo
basectl devenv-report demo --format json

The report classifies each present manifest field into one of four categories:

• supported: information Base can carry into Nix/devenv planning directly
• unsupported: host-specific or out-of-scope data that Base should not translate automatically
• lossy: information that might inform Nix/devenv, but needs explicit mapping policy before generation would be safe
• project-owned: commands, checks, demos, or shell behavior that should remain owned by the project manifest or project tools

JSON output is deterministic and includes per-classification counts:

basectl devenv-report demo --format json

Use this command when evaluating whether a Base-managed project is a good candidate for Nix/devenv support. Treat it as a compatibility report, not as a generator.

Explicit external Python venv state such as python.venv_location: external is reported as unsupported because it points to host-local Base state rather than project-owned configuration.
