+# Composite action: real LLM call (OpenAI-compatible, no mock)
+# -----------------------------------------------------------------------------
+# Every agentic workflow calls the model through THIS action so the policy
+# "ALWAYS use real LLM/AI calling" is enforced in exactly one place.
+#
+# The action performs a real HTTPS POST to ${{ secrets.LLM_BASE_URL }}/chat/completions
+# using ${{ secrets.LLM_API_KEY }}. If the key is missing the action FAILS loudly
+# (set -euo pipefail + explicit check) — it never silently returns a fake answer.
+#
+# Used by: sdlc-*.yml, aria-*.yml, livingcode-*.yml, hermes-*.yml, and every
+#           md-derived agentic workflow in this repo.
