The other-applet batch: a test script can send the common event downloads
semantically instead of raw hex.
- events.py: server-side mirrors of the PWA's event forms for Location status
(0x03), Access technology change (0x0B), Network rejection (0x12 - the
LA/RA/TA object selected by the registration group, the extended EMM cause
and the extended information object) and Data connection status change
(0x1D - status/type/TI plus the optional cause, host-clock 8.39 date-time,
location information, access technology, APN and PDP/PDN/PDU type). Fields
are validated before the run (a bad value is a script error, not a step
failure); `src` overrides the device-identities source (default terminal,
matching the Phone forms).
- The engine gains the `event` action kind; the runner builds and sends it.
The PWA's action-kind list stays in sync (drift-guarded - the guard itself
caught its own regex bug on the first run).
- Byte parity: the vectors are generated from the PWA's own builders and
pinned in tests/test_events.py; the frontend suites assert the same values.
PLMN and SCTS helpers are mirrored too.
- The Phone tab's event form shows the built "Event data (hex)" (updated as
the fields change), so every event without a builder can be used through
the raw `envelope` action.
- The test-step editor offers the event select + a JSON fields textarea;
malformed JSON refuses the save with a clear message.
- docs/test-scripts.md (the semantic-event table, an event example, the
format stamp), docs/api.md and help EN/RU updated.
Tests: 812 frontend + 717 Python; sw cache simple-v381.
