+# FE-RB-003 — Backend API degradation
+
+Trigger when terminal network/timeout/5xx failures exceed the rolling
+five-minute threshold or on one `SCHEMA_MISMATCH`. Do not expand client retry
+caps, do not retry schema mismatches, and never retry an unkeyed mutation.
+Escalate from the API client owner to backend operations and then release
+compatibility; the planned first-classification target is ten minutes.
+
+Close only after the failure rate returns to baseline, retry amplification is
+absent, critical read/write smoke passes, and schema fixtures pass.
