+# Publishes one @codat/* TypeScript SDK package to public npm.
+#
+# Written by sdk-codegen (npm_publish_pipeline.yml); do not edit by hand.
+# It runs from codatio/client-sdk-typescript at .azuredevops/npm-publish.yml,
+# because an Azure Pipelines CI trigger only fires for the repository the YAML
+# is committed to. codat-internal/sdk-codegen holds the source of truth and
+# delivers a copy into the SDK repo.
+#
+# It fires when a versioned release PR merges to main, which it recognises by a
+# change to <product>/RELEASES.md. The detect step works out which product that
+# was; a versioned PR only ever touches one product at a time, so two at once
+# will error. A manual run can override the product for testing.
+#
+# Build stage: builds and packs the package at the merged commit and runs
+# packaging checks. Publish stage: publishes the tarball under the
+# "next" dist-tag; if the version is already on npm it skips and stays green, so
+# a re-run is harmless. The npm credential lives in the
+# codat-npm-publish-packages service connection and never leaves Azure.
