It turned out to be a positioning decision rather than a feature -- it decides the
store category, the screenshots and who finds the app, and cyclists are a much
larger audience than motorcyclists. Far cheaper to settle before a store listing
exists.
Specified the schema (a text enum on Trip), and flagged that this is the first
real migration the port will ship: the destructive fallback is gone, so it needs
addColumn with a motorcycle default, schemaVersion 2, and a test that opens a v1
database and asserts the rides survive. Getting that path right matters more than
the feature.
The value is in driving per-activity defaults rather than labels: the 1.5 km/h
noise floor is wrong for walking, 10 km/h histogram buckets are useless for
running, and the elevation smoothing window was tuned for 2 Hz road speed.
Also recorded a UI constraint: no picker in front of Start. The founding premise
is press-and-go with gloves, so default to the last activity used and make it
editable on trip detail afterwards.
