alro65 700756c16f sprint-0: foundations -- data model, seed library, tests, demo
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.

## [Unreleased]
## [0.1.0] — Sprint 0 — Foundations — 2026-05-17
### Added
- Repository structure following the layout defined in the project brief (section 11)
- Python package skeleton `arautopilot` with submodules:
- `core/` — data model (Pydantic v2): modes, alarms, actuator config, PID config,
vessel config, knob state, project config, IDs
- `library/` — curated seed: 2 actuator profiles (hydraulic reversible,
electric DC reversible) and 2 default tunings (yacht motor planeo 30 m, 40 m)
- `studio/` — empty stubs for Sprint 4
- `tests/` — pytest suite covering the core data model
- Firmware skeleton: `firmware/ar_autopilot_v1/src/hal/pinout.h` only —
21 I/O assignment for the AR-NMEA-IO v1.0 board, no functional code yet
- Build configuration:
- `pyproject.toml` with Pydantic v2, PyYAML, python-dateutil
- Dev dependencies: pytest, pytest-cov, ruff, mypy
- Ruff + mypy strict configuration
- `examples/sprint0_demo.py` — end-to-end project creation, save, and reload
- Documentation moved/created:
- `docs/AR_Autopilot_brief.md` — full project brief
- `docs/architecture.md` — one-page architecture overview
- `LICENSE.txt` — Proprietary, all rights reserved
- `.gitignore` covering Python, Flutter, PlatformIO, IDEs, Windows artifacts
### Notes
- **No functional firmware**, Studio GUI, or display in this sprint — those
start in Sprint 1, 4, and 4 respectively.
- The seed PID tunings are **conservative starting values** drawn from
classical marine control literature (Fossen, Perez). They are explicitly
**not** the integrator's affinated production values, which remain IP.
- Python ≥3.11 required.
