Adds OmniLinkMessage (0x10) outer-packet handling to the mock so the
v1 path no longer requires a real panel for testing. Exercised over
UDP because OmniClientV1 is UDP-only by design, but the dispatcher
itself is transport-agnostic and the TCP _handle_client routes
OmniLinkMessage packets through the same _dispatch_v1 method too.
Coverage today:
* RequestSystemInformation (17) -> SystemInformation (18)
* RequestSystemStatus (19) -> SystemStatus (20), 8 area mode bytes
* RequestZoneStatus (21) -> ZoneStatus (22), short + long form
* RequestUnitStatus (23) -> UnitStatus (24), short + long form
(long form auto-selected for indices > 255)
* RequestThermostatStatus (30) -> ThermostatStatus (31)
* RequestAuxiliaryStatus (25) -> AuxiliaryStatus (26) (zero records)
* UploadNames (12) -> NameData (11) streaming, lock-step
Ack-driven across Zone/Unit/Button/
Area/Thermostat, terminated by EOD (3)
* Command (15) -> Ack (5) / Nak (6), reuses v2 state
mutator so light-on/off, set-level,
bypass-zone, restore-zone all work
* ExecuteSecurityCommand (102) -> Ack (5) / ExecuteSecurityCommandResponse
(103) on bad code, with structured
status byte preserved
* MessageCrcError -> v1 Nak (opcode 6)
The dispatcher writes replies wrapped in OmniLinkMessage (16) outer
packets (vs OmniLink2Message (32) used by v2) so OmniClientV1 routes
them correctly. The 4-step handshake is shared with v2 -- it's
protocol-version-agnostic at the outer-packet layer.
UploadNames state is panel-instance scoped via _upload_names_cursor
(int | None) -- there is only one active session at a time on the
mock so a single cursor suffices.
tests/test_e2e_v1_mock.py: 13 cases driving OmniClientV1 through the
mock's UDP socket, covering the full read API + UploadNames streaming
+ write methods + structured-failure path on a wrong security code.
Full suite: 400 passed, 1 skipped (was 387 / 1).
