Initial commit. Delivers what the brief calls 'Sprint 0 - Foundations'
(see docs/AR_Autopilot_brief.md section 12):
- Complete repository structure (arautopilot package + firmware, display,
installer, tools placeholders + docs).
- Core data model (Pydantic v2): modes, alarms, actuator config, PID
config + gain scheduling, vessel config, knob state machine, project
config with YAML/JSON serialisation.
- Seed library: 2 actuator profiles (hydraulic & electric DC reversible)
and 2 default tunings (yacht motor planeo 30 m and 40 m). Conservative
literature values, NOT the integrator's production tuning IP.
- Firmware skeleton: only src/hal/pinout.h with the 21 I/O contract for
the AR-NMEA-IO v1.0 board. No drivers, no main loop.
- Studio stubs (real PySide6 app starts in Sprint 4).
- pytest suite (80 tests, all green): modes, alarms, actuator, PID
(incl. gain interpolation and the +/-50% adaptive bound from brief
section 6), vessel, knob state, project config, library loader,
end-to-end roundtrip.
- examples/sprint0_demo.py - the acceptance demo from the brief.
Acceptance criteria met:
- pytest green (80/80)
- demo creates, saves (YAML + JSON), reloads, and verifies a full
ProjectConfig using the seed library
- repository ready for tag `sprint-0-approved`
See CHANGELOG.md for the detailed scope.
