Five reported issues, plus the action that makes an explicit drain possible: - on_fail is honoured by every step failure: an expectation with no pending command (or a FETCH that returns nothing) fails as a Command/Fetch check at the step's level instead of raising past it; the default still stops the run, on_fail "warning" continues (the tolerant consume-if-pending form). - the run cleanup answers ok (0x00) and keeps draining while the TR answers 91XX (bounded); a cancel is only sent when a script asks for it - it tells the card the user aborted the session and pushes assertive applets onto an error path. - new `proactive` action: STATUS rounds consume every announced command (respond/first TERMINAL RESPONSE results, attempts/interval_ms bound) until the card answers 9000; an optional require asserts at least one drained command (an empty drain fails it), the final SW is the step's SW check and a still-pending command is handed to the next step. PWA editor + summary + validation, EN/RU help, docs, action-kind drift test. - the PoR response form follows the command's TAR: _tar_is_rm (preset role entries + the TS 101 220 Annex D ISD/RFM allocations) decides; a non-RM TAR's reply is always raw (TS 102 226 4) - no fabricated status word even when the bytes happen to parse (01 00 0B 91 ... used to read as SW 000B). - a secured data too short for the compact structure (a 2-byte applet reply) is recovered by _por_header_parse (the decode minus the compact parse; a malformed packet or a failed RC/CC/DS check still yields no por) and reported raw, so short applet replies are assertable via por.data.
