═══════════════════════════════════════════════════════════════════════════════ ARCHITECTURE PRINCIPLES (ENFORCED) ═══════════════════════════════════════════════════════════════════════════════

The Kernel is the Single Authority For:

  1. Global state (position, velocity, attitude, power)
  2. Time stepping and loop control
  3. Module execution order and sequencing
  4. Error monitoring and recovery
  5. Data aggregation and coupling

No direct module-to-module communication allowed. All interaction flows through kernel only.

Enforcement Mechanisms: ✓ Frozen dataclasses (immutability at language level) ✓ Interface contracts (PhysicsModule.compute(input) → output) ✓ State snapshot mechanism (all modules see same state) ✓ Deterministic ordering (sorted module names) ✓ Single state mutation point (kernel only) ✓ Error isolation (one module failure doesn't cascade)

Results: ✓ Fully deterministic and reproducible ✓ Trivial to parallelize (modules are pure functions) ✓ Independent module testing (no kernel needed) ✓ Clear separation of concerns ✓ Production-grade error handling ✓ Mission-critical auditability

═══════════════════════════════════════════════════════════════════════════════ CAPABILITIES DELIVERED ═══════════════════════════════════════════════════════════════════════════════

  1. MISSION DEFINITION ✓ YAML-based configuration (human-readable) ✓ Programmatic API (Mission class) ✓ Fluent builder pattern (MissionBuilder) ✓ Type-safe enums (SolverType, EventType, PhysicsModuleType)

  2. PHYSICS SIMULATION ✓ Two-body gravitational acceleration ✓ Perturbation models (J2, atmospheric drag, third-body) ✓ Solar radiation pressure ✓ Thermal equilibrium ✓ Stochastic environment models (solar cycle, CME, radiation) ✓ Attitude dynamics (quaternion-based) ✓ Power system modeling

  3. NUMERICAL INTEGRATION ✓ RK4 symplectic integrator ✓ Adaptive timestep capability ✓ Energy monitoring (conservation checks) ✓ Convergence criteria ✓ Error handling (Inf/NaN detection)

  4. EVENT SYSTEM ✓ Discrete event detection ✓ Event callbacks (user-defined handlers) ✓ Event logging (stored in audit trail) ✓ Event metadata (type, time, description, data)

  5. DATA PERSISTENCE ✓ YAML configuration export/import ✓ HDF5 trajectory storage (gzip compression) ✓ SQLite audit logging (queryable) ✓ Metadata embedment (spacecraft, solver, mission params)

  6. REPRODUCIBILITY & AUDITABILITY ✓ Deterministic execution (same seed = identical trajectory) ✓ Seed tracking (stored in config + audit) ✓ Complete audit trail (every action logged) ✓ Configuration archival (YAML export) ✓ Bit-for-bit replay capability

  7. ERROR HANDLING ✓ Graceful degradation (one module failure ≠ simulation failure) ✓ Error isolation (module-level try/catch) ✓ Error logging (audit trail) ✓ Invalid state detection (finite value checks) ✓ User notifications (callbacks)

  8. EXTENSIBILITY ✓ Module registration at runtime ✓ Custom physics modules (implement PhysicsModule) ✓ Custom event handlers (user callbacks) ✓ Custom enums (add to core.py) ✓ Custom solvers (replace integrator)

═══════════════════════════════════════════════════════════════════════════════ EXAMPLE USAGE (Complete Workflow) ═══════════════════════════════════════════════════════════════════════════════

1. Load configuration from YAML

from io.config_loader import load_config config = load_config("missions/solar_sail_2body.yaml")

2. Create mission with physics modules

from api import Mission from models.wrappers import TwoBodyModule, SolarRadiationPressureModule

mission = Mission(config) mission.add_physics_module("orbital_mechanics", TwoBodyModule(mu=1.327e20)) mission.add_physics_module("sail_srp", SolarRadiationPressureModule(...))

3. Run simulation

result = mission.run()

4. Export all results

from io import export_all export_all(result, output_dir="outputs/run_001")

5. Analyze results (load trajectory from HDF5, query audit log)

from io.trajectory_export import load_trajectory_hdf5 from io.audit_export import AuditDatabase

data = load_trajectory_hdf5("outputs/run_001/solar_sail_2body.h5") db = AuditDatabase("outputs/run_001/solar_sail_2body_audit.db") db.connect()

Query events

events = db.query_events() print(f"Detected {len(events)} events")

Analyze trajectory

import matplotlib.pyplot as plt r = data["state"]["r"] plt.plot(r[:, 0] / 1e9, r[:, 1] / 1e9) plt.xlabel("x [Gm]") plt.ylabel("y [Gm]") plt.show()
