The event list tables carried labels like "12 Reserved for 3GPP - Network rejection (TS 31.111 7.5.2)". The phrase is an ETSI-to-3GPP document pointer, not a usage restriction, and it is not what a user needs - the event name is. - EVENT_NAMES (PWA + server mirror): the 3GPP-assigned codings carry their plain TS 31.111 7.5 name ((I-)WLAN access status, Network rejection, CSG cell selection, IMS registration, Incoming IMS data, Data connection status change, CAG cell selection, Slices status change). - 0x20-0x22: "Reserved (future usage)" (no attribution). - 0x0B/0x14: the spec's full "(single access technology)" / "(multiple access technologies)" wording instead of the cryptic "(single)/(multiple)". - tests pin the exact names and that no name contains the cross-reference. 652 frontend / 500 Python green; version 3.6.22; sw simple-v295.
