description: "Internal composite for the flag-on kind: script path (typed-workflows WF-COMP-31 / workflow-variables WV-19). Brings the shared-variables filesystem context AND the AU-51 CP write credential (cp-service-token/v1 sets CP_SERVICE_TOKEN_FILE in the entrypoint process env before shell_runner runs). NOT a model-bearing composite — the kind: script compiled shape is cli=\"shell\", params.cmd=<cmd>; this composite provides the harness layers that path needs and nothing else."

# Order matters only for HC-6 env last-writer-wins / HC-8 git identity. The two
# layers here have disjoint env vars (shared-variables sets WORKFLOW_VARIABLES_*
# paths, cp-service-token sets CP_SERVICE_TOKEN_FILE) and no overlapping git
# identity, so the listed order has no observable merge effect — both layers
# reach the script-node container either way.
layers:
  # spec/workflow-variables.md WV-19 / spec/harness.md HD-14 — agent-facing
  # /variables/ context (CLAUDE.md mounted at /opt/harness/context/shared-variables/CLAUDE.md)
  # plus WORKFLOW_VARIABLES_ROOT=/variables and templated WORKFLOW_VARIABLES_SELF=<step_path>.
  # Provides the [shared-variables] tag used by the dispatcher's extra_layers injection.
  - context: shared-variables/v1
  # spec/typed-workflows.md WF-COMP-31 "AU-51 credential env seam" — this layer's
  # init.sh restages the ESO-mounted CP-service-token secret (root-owned mode 0400)
  # to an agent-owned 0600 copy at /run/agent/cp-service-token/token and exports
  # CP_SERVICE_TOKEN_FILE pointing at it. Verified: env.CP_SERVICE_TOKEN_FILE is set
  # on the entrypoint process environment before shell_runner runs (entrypoint reads
  # os.environ via env=os.environ.copy() in subprocess.run at entrypoint/runners/shell.py:73,
  # so the same credential channel an agent node gets reaches a script node unchanged).

  # spec/typed-workflows.md WF-COMP-34 (bug 3bee78fa, 2026-10-02) — read-only
  # project-repo clone for harness-path kind: script nodes. Layered LAST so
  # its clone runs after the two AU-51 wiring layers and before the script
  # starts (init.sh order: shared-variables -> cp-service-token -> repo-readonly).
  # When AGENT_REPO_URL is unset (the pre-fix runtime, or any template that
  # does not declare agent_repo) this layer is a no-op; the V2 guard
  # (entrypoint/entrypoint.py:901-906) does NOT trip because the unset case
  # is a no-op there too. Layered-in instead of layering agent-repo/v1
  # because that context's fork management and push side effects are wrong
  # for a read-only script node (see bug item body).
