Caught live on the owner's X50 mid-cleanup with temporary logging: the
recorder saw every camera state change and rejected every one, because
server-side Tasshack keeps vacuum_position as a Point OBJECT — it only
becomes a dict when serialised to the frontend, which is why the card
adapter (and MCP inspection) always saw a dict and the stub test
faithfully reproduced the same wrong assumption. getattr fallback added,
regression test pinned, diagnostic logging removed (setup line kept at
INFO).
test_trail_recorder injected fake homeassistant modules into sys.modules
at import time; every pytest_homeassistant_custom_component fixture in
the same session then failed with 'module homeassistant has no attribute
util'. The stubs now live inside a snapshot that is restored in a finally
block.
Only TrailBook was covered; the HA-facing half — subscription callback,
attribute dialects, map-id resolution, run end on docking — had no test
at all. It does now, against a stubbed hass, which is also where the
missing behaviour showed up: recording started at the NEXT state change,
so an HA restart (or finishing calibration) mid-cleanup dropped the
opening seconds of the path. Sampling is factored out and runs once per
source on setup and on every refresh.
