# validate-project - deterministic CLI over ProjectValidator (intent 190).
#
# Checks whether a registered project's spawn is structurally complete: the
# project directory exists, project.yml exists and parses, a root AGENTS.md
# exists, and the store/ and INDEX.md exist. plastic-project-creating runs
# this as a self-check before announcing a spawn as done; any agent or human
# can run it on one slug.
#
# Usage:
#   validate-project <slug> [--home <path>]
#
# Exit codes: 0 (structurally complete), 1 (incomplete; report on stderr), 2 (usage).
# --home <path> overrides the Plastic home (default: ~/.plastic).
