+# ─────────────────────────────────────────────────────────────────────────────
+# ai.env.template — AUTHORITATIVE template for ai/ai.env (rendered by
+# deploy/provision-stack.py per secrets/secrets-map.yaml).
+#
+#   - This file IS the complete key list for ai.env. The whole file is
+#     rendered on every provisioning run — no line surgery, so a key can
+#     never silently go missing again (root cause of the 2026-09-03 outage).
+#   - Key names match EXACTLY what ai/ai.yaml references (AI_<SERVICE>_*
+#     naming adopted on main 2026-09-06).
+#   - Non-secret config lives here as LITERAL values (visible, reviewable).
+#   - Secret values are dollar-brace placeholders resolved from the CI env
+#     (Woodpecker from_secret vars) at provisioning time. provision-stack.py
+#     FAILS HARD if any placeholder is missing/empty.
+#   - The rendered ai/ai.env exists only on the host (gitignored).
+#   - Rendered by provision-stack.py, NOT Woodpecker's yaml preprocessor —
+#     single-dollar placeholders are safe here (deploy.yml's double-dollar
+#     rule does NOT apply to this file).
+#
+# Consumed by ai/ai.yaml. DOMAIN_NAME comes from deploy/global.env, not here.
