     - Hardened local Gitea webhook matching for case-insensitive providers and normalised repository URLs/names.
     - Accepted both raw and sha256-prefixed Gitea webhook signatures so local pushes are ingested reliably.
     - Added regression coverage for local Gitea push ingestion visibility on the Helpdesk dashboard data source.

+- version: 1.10.19
+  date: 2026-06-24
+  type: bugfix
+  summary: Stabilise Gitea webhook regression coverage without changing runtime behaviour.
+  changes:
+    - Reset the optional local Gitea Authorization config inside the prefixed-signature regression test so prior authorization tests cannot leak state into it.
+    - Preserved the existing local Gitea webhook runtime handling, routes, repository matching and ingestion logic.
+    - Preserved append-only changelog history.
