+# OWNd is what every MyHOME installation runs. A change here is only as safe
+# as the integration that consumes it, so every push and pull request is
+# checked against MyHOME's development branch, with this checkout installed
+# in place of the pinned release:
+#
+#   corpus  - the 255-vector golden corpus (tests/golden) plus MyHOME's own
+#             smoke gates: the parser must produce the same objects for the
+#             same frames. Fast and required.
+#   suite   - MyHOME's full test suite. Catches the behavioural coupling
+#             a signature or state-machine change introduces. Required too:
+#             a failure here means the pin bump that follows a release
+#             would fail, so it is better learned now.
+#
+# Both run on Python 3.14 only: that is what Home Assistant 2026.3+ needs,
+# and the OWNd matrix already covers the older interpreters.
