provides: [shared-variables]

# WV-20: both env vars are set by THIS harness layer (not the entrypoint, not
# the container backend). WORKFLOW_VARIABLES_ROOT is static; WORKFLOW_VARIABLES_SELF
# is templated by the composer at harness-composition time on the dispatcher,
# substituting the node's resolved step_path (the SAME value WV-15 derives at mint
# time). A task with no shared-variables/v1 layer (unstamped) has neither env var
# set, and /variables does not exist for it at all.
env:
  WORKFLOW_VARIABLES_ROOT: /variables
  WORKFLOW_VARIABLES_SELF: "{{ step_path }}"
