+# Monthly SKU catalog refresh.
+#
+# Runs on the 1st of each month at 09:00 UTC and on manual dispatch.
+#
+# Does two things:
+#   1. `--refresh`: pulls latest PAYG prices from Oracle's public API,
+#      updates kb/pricing/oci-sku-catalog.yaml, and opens a PR if anything
+#      changed.
+#   2. `--discover`: reports SKUs present in the API but absent from the
+#      catalog (filtered to serviceCategory values already curated).
+#      If new SKUs are found, opens a Gitea issue listing them by category
+#      for manual review.
+#
+# Tokens:
+#   secrets.GITEA_TOKEN — must have repo:write + issues:write.
+#   If not set, the run logs the diff/discover output as an artifact and
+#   leaves the rest (branch push, PR, issue) as a no-op.
