Scope and intent
----------------
* This dedication covers the OBSERVATION DATA only. The swelter source code is
  licensed separately under the Apache License, Version 2.0 (see LICENSE).
* The data is published open by default and exported through open standards so
  that anyone — a resident, a reporter, a researcher — can audit, reuse, or fork
  it, and so a community can leave with its data and stand the network up
  elsewhere with no lock-in.
* The observations are aggregate environmental measurements only. They contain
  no personal information and no field capable of locating a person. Node
  locations are published snapped to a coarse grid unless a host opts in to a
  precise location (see docs/governance.md).
* Attribution is not legally required, but is appreciated: "Environmental data
  from the swelter community sensing network."

No warranty
-----------
The data is provided "as is", without warranty of any kind. Low-cost sensor
readings carry uncertainty; each value travels with its calibration state and,
when calibrated, a published uncertainty. Consult docs/calibration.md before
relying on a value, and treat readings flagged provisional accordingly.
