The script author read por.sw as the envelope SW, so a por.sw expectation on an applet's own TAR failed with (none). - docs/test-scripts.md: a 'The three status words (envelope SW / PoR status / R-APDU SW)' table in the authoring section - where each one comes from, the script field and the report row - plus a cross-reference from the por check paragraph; help EN/RU 8.9 points at it. - a failed por.sw check on a response_type: 'raw' decode carries the check detail 'the response is application data - an applet's own TAR has no R-APDU SW; assert it with data' (the PWA renders check details). - the runner's log prints APP DATA=<hex> (no R-APDU SW) for application responses instead of the misleading R-APDU SW=(none) data=...; the compact/scripting lines are unchanged. - the step editor's custom-PoR block gets a one-line hint about the same.
