alro65 e4812e9b44 sprint-4: Project Editor + .appack compiler + IRudderActuator HAL + dual sensor config 
Cherry-pick of ab28cb7 onto main (was missing from main branch history).

Python:
- arautopilot/core/sensor_config.py: RudderSensorConfig + DualRudderSensorConfig
  (AS5048A SPI / potentiometer, dual with cross-validation thresholds)
- arautopilot/core/vessel_config.py: add sensors: DualRudderSensorConfig field
- arautopilot/studio/compiler/appack.py: .appack compiler (ZIP with
  manifest.json + project.yaml + firmware_config.h + install_notes.txt)
- arautopilot/studio/editors/project_editor.py: full project config editor
  (vessel / actuator / sensors / PID, RBAC-gated fields, save/load .yaml/.json)
- arautopilot/studio/main_window.py: wire ProjectEditorWidget into Project tab
- tests: test_sensor_config.py (11 tests) + test_appack_compiler.py (10 tests)

Firmware:
- hal/rudder_actuator_iface.h: IRudderActuator abstract interface
- hal/rudder_actuator_hydraulic.h: reversible hydraulic pump (LEDC PWM)
- hal/rudder_actuator_electric.h: reversible DC motor + deadband compensation
- hal/rudder_actuator_factory.h: build-time type selection via AR_ACTUATOR_TYPE

Tests: 483 passed (was 462, +21 Sprint 4)

alro65 5f9b445572 sprint-7: Commissioning wizard + relay ZN auto-tuner + NVS config + knob encoder 
Python:
- autotuner.py: RelayAutoTuner (Astrom-Hagglund relay method) → TunerResult
  with Ku/Tu; TunerResult.to_pid_gains() applies ZN formulas
- commissioning_wizard.py: 4-phase state machine (RUDDER_LIMITS → SENSOR_CAL
  → AUTO_TUNE → DONE); transport-injected for testability; abort on invalid cal
- test_autotuner.py: 17 tests covering relay convergence, ZN formulas,
  wizard full-run, abort, ADC swap, identical-ADC guard

Firmware:
- nvs_config.h/cpp: NVS-backed CalibrationData store (adc limits, rudder angles,
  outer Kp/Ki/Kd, commissioned flag); float stored as uint32 via memcpy
- knob_encoder.h/cpp: quadrature rotary encoder on GPIO 16/17 with ISR Gray-code
  decode; knob_arm coil arms for 5 s window; updates heading setpoint ±1 deg/detent
- modbus_slave.cpp: COIL_CMD_KNOB_ARM now calls knob_encoder_set_armed()
- main.cpp: nvs_config_init/load at boot; apply commissioned calibration to
  rudder sensor and outer loop gains; start knob encoder task

Tests: 326 passed | Flash: 28.5%

alro65 42ee63b776 sprint-3: PID outer + Heading Hold + ROT feed-forward + gain scheduling 
End-to-end implementation per docs/sprint-3-plan.md.

Closes the cascade: outer loop (heading control, 10 Hz on Core 1) drives
the inner loop (rudder position control, 50 Hz from Sprint 2). First real
mode other than STANDBY is now activable: HEADING_HOLD.

Builds: pio run -e esp32-dev SUCCESS, RAM 6.8%, Flash 27.1% (355 KB).
Tests: pytest 258/258 green (231 Sprint 2.5 + 27 Sprint 3 new).

Python (arautopilot/studio/simulator/):

- vessel_heading.py: first-order yaw model. ROT responds to
  rudder*speed; damping returns ROT to zero when rudder is centred.
  Defaults tuned so 5 deg rudder @ 10 kn -> ~3 dps steady-state ROT.
  Includes heading_error_deg() shortest-arc helper.
- pid_outer.py: pure-Python outer heading PID. Anti-windup via back-
  calculation, gain scheduling by SOG, deadband, derivative LPF,
  output saturation, ROT feed-forward (brief sec. 6 -- the term that
  distinguishes a premium autopilot from a basic one), rate limit on
  produced rudder setpoint, shortest-arc heading wrap-around.

Firmware (firmware/ar_autopilot_v1/src/pid/):

- pid_outer.h: header-only C++17 port. Same algorithm, same variables,
  same numerics. Fixed-capacity gain schedule (up to 8 points).
- pid_outer_task.{h,cpp}: 10 Hz FreeRTOS task on Core 1. Subscribes to
  TWDT. Reads heading + ROT from the NMEA 2000 snapshot. Uses
  operator-configurable SOG (default 15 kn until PGN 129026 wiring in
  Sprint 5). Pushes rudder setpoint into the inner loop only when
  current_mode == HEADING_HOLD.

Modes (firmware/ar_autopilot_v1/src/modes/standby.cpp):

- HEADING_HOLD activable via request_mode(). Pre-conditions:
    * NMEA 2000 heading sensor valid (fresh PGN 127250)
    * Rudder sensor valid (median filter filled)
  On success, captures current heading as initial setpoint so the
  operator doesn't get a sudden swing toward an old setpoint.

Modbus (regenerated from YAML):

- 7 new INPUTs (50-56): outer heading setpoint, produced rudder
  setpoint, error, current SOG, live kp/ki/kd.
- 5 new HOLDINGs (24-28): writable heading setpoint, SOG override,
  outer base gains. Writing any of kp/ki/kd disables the built-in
  3-point gain schedule (operator override).

Tests:

- test_vessel_heading_simulator.py: 6 dynamics tests + 9 parameterised
  heading_error_deg edge cases (wrap-around).
- test_pid_outer_python.py: 12 tests covering gain interpolation,
  per-tick PID behaviour (deadband, sign, ROT feed-forward,
  saturation, rate limit, allowed=false), and three end-to-end cascade
  tests (positive step, negative step, wrap-around 360->10).

Cascade verification: outer + inner + rudder dynamics + vessel-heading
simulator settles a 30 deg step within +-2 deg in 60 s.

NOT in Sprint 3 (intentional):
  - True Course / Track Keeping / Dodge -- Sprint 5
  - Off-course alarms + auto-disengage on sensor loss -- Sprint 6
  - COG / SOG / Position via N2K PGN 129025/9/6 -- Sprint 5

alro65 13a2867ef6 sprint-2.5: RBAC 4 roles + Studio bootable + Flash Console 
End-to-end implementation per docs/sprint-2.5-plan.md.

New requirement added by user mid-sprint: 4-role RBAC (Super Admin /
Engineer / Owner / User) with dual-auth for Engineer flashing firmware,
plus a "mini Arduino IDE" inside the Studio.

Tests: pytest 231/231 green (129 Sprint 2 + 102 Sprint 2.5 new).

RBAC core (arautopilot/core/):

- rbac.py: 4 roles, 12 capabilities, immutable capability matrix,
  has() / capabilities_of() / require() / requires_dual_auth() helpers.
  Engineer flashing firmware needs SA approval; everything else is
  single-factor.
- user.py: User model with PBKDF2-HMAC-SHA256 PIN hashing (200k iters,
  16-byte salt, self-describing hash format for future migrations).
  4-8 digit numeric PINs enforced.
- user_store.py: JSON-backed user database. seed_demo_users() for
  first-run UX.
- audit.py: append-only JSONL audit log. AuditEvent with timestamp,
  user_id, role, action, target, outcome, reason, secondary_user_id
  for dual-auth, optional extra payload. Crypto signing of lines
  deferred to Sprint 8.

Studio GUI (arautopilot/studio/):

- app.py: real entry point (replaces Sprint 0 stub). --seed-demo
  populates demo users without launching GUI; --data-dir overrides the
  ~/.ar-autopilot/studio/ default.
- session.py: Session + SessionHolder. check() always audits the
  decision; verify_super_admin_pin() + log_dual_auth_grant() for
  dual-auth flows.
- login_window.py: modal login dialog with user picker + PIN field.
  Audits login attempts (success and bad-PIN denials).
- main_window.py: top-level window with sidebar (user + role + caps)
  and tab area (Overview, Flash Console, Project placeholder,
  Telemetry placeholder).
- flash_console.py: the "mini Arduino IDE". Lists serial ports via
  pyserial; picks firmware variant (esp32-dev / esp32-debug); compiles
  via 'pio run'; flashes via 'pio run -t upload --upload-port <port>';
  streams pio output to a dark-themed read-only console; supports
  cancel. For Engineer flashes, asks the Super Admin for their PIN
  inline before invoking pio. Records dual-auth grant + pio exit code
  in the audit log.

Dependencies:

- New [project.optional-dependencies] group 'studio': PySide6>=6.6,
  pyserial>=3.5, platformio>=6.1. Kept optional so the core can be
  installed in lean / CI environments.

Tests (arautopilot/tests/):

- test_rbac.py: 32 tests for capability matrix, dual-auth policy,
  no-privilege-escalation invariants, partial overlap between roles.
- test_user.py: 11 tests for PIN hashing, verification, salting,
  serialisation, field validators.
- test_audit.py: 9 tests for JSONL append, immutability, round-trip,
  corrupt-line detection, dual-auth event shape, blank-line tolerance.
- test_user_store.py: 10 tests for CRUD, persistence, role filtering,
  demo seed idempotency.
- test_session.py: 9 tests for capability checks + audit side effects,
  SA PIN verification, dual-auth recording, SessionHolder lifecycle.
- test_studio_smoke.py: 5 headless tests verifying Studio modules
  import without a display server, --seed-demo works, helpers safe to
  call without hardware.

NOT in Sprint 2.5 (intentional):
  - Crypto signing of audit log lines (hash-chain) -- Sprint 8
  - HWID binding of the user store -- Sprint 8
  - Project configurator + .appack compiler -- Sprint 4
  - Flutter bridge display -- Sprint 4
  - Telemetry dashboard tab -- Sprint 4
  - Serial monitor as a separate tab -- future enhancement

alro65 295efa2d83 sprint-2: PID inner loop + Python rudder simulator 
End-to-end implementation per docs/sprint-2-plan.md.

Builds: pio run -e esp32-dev SUCCESS, RAM 6.8%, Flash 26.8% (351 KB).
Tests: pytest 129/129 green (110 Sprint 1 + 19 Sprint 2).

Python (arautopilot/studio/simulator/):

- rudder_dynamics.py: marine-realistic physical model of a hydraulic
  rudder actuator. Defaults tuned so 100 % PWM produces steady-state
  v_max ~5 deg/s, matching the brief's "typical 3-6 dps" for a 30 m
  yacht. Includes deadband, min-useful PWM snap, port/stbd asymmetry,
  end-stops, optional external torque, RunRecorder helper.
- pid_inner.py: pure-Python reference PID. Anti-windup via back-
  calculation, setpoint rate limit, setpoint deadband, derivative LPF,
  actuator non-linearity compensation. This module is the algorithmic
  source of truth; C++ firmware is a line-by-line port.

Firmware (firmware/ar_autopilot_v1/src/pid/):

- pid_inner.h: header-only C++17 controller, byte-equivalent port of
  pid_inner.py. Compiles on ESP32 toolchain AND on host g++/clang/MSVC
  (no Arduino dependencies) -- ready for native Unity cross-validation
  once a host compiler is installed.
- pid_inner_task.{h,cpp}: FreeRTOS task wrapper. 50 Hz on Core 1
  (real-time core). Subscribes to TWDT, bleeds integrator during
  STANDBY, surfaces telemetry + tunables via the Modbus slave.

Modbus map (regenerated from YAML):

- 6 new INPUT registers (40-45): setpoint, output, error, kp/ki/kd live
- 4 new HOLDING registers (16-19): writable setpoint + kp/ki/kd req
  (writes propagate atomically; zero kp rejected as ILLEGAL_DATA_VALUE)

Tests:

- test_rudder_simulator.py: 9 tests (zero-input rest, full deflection,
  end-stop saturation, deadband, min-useful snap, asymmetry, recorder
  API, invalid dt, end-stop velocity zeroing).
- test_pid_inner_python.py: 10 tests (positive/negative step response,
  setpoint deadband holds, anti-windup bounds under saturation,
  allowed=false bleeds integrator, actuator deadband + asymmetry
  compensation, output saturation, rate limit, disturbance rejection).

NOT in Sprint 2 (intentional per brief sec. 12):
  - Outer heading PID, gain scheduling by SOG, ROT feed-forward
    (those land in Sprint 3)
  - Cross-validation tests via ctypes (need host C++ compiler that
    this Windows machine lacks; algorithmic parity enforced by review)

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.
