+# ── Workflow Design Notes ──────────────────────────────────────────────────────
+# 1. version-stamp computes a nightly version string for artifact naming and
+#    traceability (e.g. "0.8.0.dev20250716"). The actual wheel package version
+#    is determined by pyproject.toml inside the reusable _build-wheel.yaml.
+# 2. Build jobs use the reusable _build-wheel.yaml which does its own checkout
+#    and derives VERSION from GITHUB_REF_NAME / pyproject.toml.
+# 3. publish-testpypi uploads all nightly-* artifacts to TestPyPI.
+# 4. nightly-gate aggregates results; notify-failure files an issue on failure.
