That took out 60 of 72 tests on 2026-07-25. GET cannot round-trip it either: it resolves the stored row overlaid with REDIS_* env and never reads YAML, so on a fresh deploy it cannot see YAML ssl to echo back. A safe test needs an isolated proxy, or LIT-4816 fixed so a partial write cannot downgrade transport. Do not re-add a read-then-write-back test against a shared proxy."}

+Cache settings and the Vault config override are deliberately not covered here.
+Both routes reconfigure the whole proxy: /cache/settings persists what it receives
+into a row that outranks the YAML cache_params and is re-applied on a timer, and
+/config_overrides/hashicorp_vault swaps the process-wide secret manager. Neither can

+isolated proxy before a test lands. Do not add a read-then-write-back test for
