Concepts

These documents explain the technical model behind the user-facing commands.

• Cross-platform support — supported OS/shell mappings and platform mechanics
• Filesystem safety — isolated-root ownership, staging, cleanup, and recovery boundaries
• SDK discovery and release metadata — channel/version discovery and exact-version metadata responsibilities
• Bootstrap source preservation and reproducibility — how file-based bootstrap preserves source identity
• Supply-chain integrity and trust boundaries — remote artifacts, checksums, and residual trust

For operation semantics, start with Commands. For stricter implementation-independent behavior, see Behavioral contracts.
