# Probe the Topaz directory's Check API to verify the seeded manifest
# correctly resolves reader/steward/outsider permissions for the
# Markitect internal-document fixture. Exits 0 if all checks match
# expectations.
#
# This probe deliberately uses the directory Check API rather than the
# authorizer Is API. The manifest permissions are the substrate the
# Topaz adapter (FLEX-WP-0004 T01) and the standalone evaluator both
# consult; demonstrating it works end-to-end here is the spike's actual
# validation question. Bridging flex-auth's Rego input shape into
# Topaz's raw authorizer input is adapter work, intentionally out of
# this spike's scope (see docs/topaz-mapping-spike.md §"Implementation
# Notes").

# 3. Eve has no relation to the document, so read should be denied.
