Phase 0 workspace hygiene for the `project-system` cluster is pending. Phase 1A — a capability-ledger primitive prototype binding C2SP signed-note multi-signature checkpoints to capability invocation — is planned work. Phase 1B — the `moonshot-toolkit` Rust CLI for orchestrating seL4 builds with a reproducible-build harness — is planned foundational work. NetBSD compat-bottom prototype, TOPIC and GUIDE drafting, and the minimal moonshot-kernel capability subset are subsequent phases.
