 ### Added
+- Ranked diagnosis causes carry a plain-language summary.
 - `maping-server --version` prints the version and commit linked into the binary.
 - `make cover` enforces a single coverage floor (`COVER_MIN`), and `make audit` depends on it.
 - `make preflight` gates `make up`, refusing to start production when `.env` is missing or still carries `env.sample` defaults.
 
+### Changed
+- The client accepts a key-embedded origin only under the hosted `mapi-ng.com` domain, and otherwise falls back to the default endpoint. Self-hosted deployments whose keys embed a private domain must set `MAPING_TRUST_KEY_ORIGIN=1`.
+- The runtime container image runs as unprivileged uid 1001 instead of root. Volumes written by an earlier image may need their ownership adjusted.
+
 ### Fixed
-- The runtime container image runs as an unprivileged user instead of root.
-- The client no longer falls back to an unreachable default ingest endpoint, and accepts a key-embedded origin only under the hosted domain unless `MAPING_TRUST_KEY_ORIGIN` is set.
+- The client default endpoint pointed at an unreachable host. It is now `https://www.mapi-ng.com`.
