## Ranked actions

| Rank | Action | Score | Confidence proxy* | Hard-constraints |
|---|---|---|---|---|
| 1 | Reroute via illuminated ridge corridor | 0.728 | 0.84 | satisfied |
| 2 | Enter conservative safe mode | 0.669 | 0.92 | satisfied |
| 3 | Hold position until relay window | 0.640 | 0.78 | satisfied |
| 4 | Continue direct route to science target | 0.253 | 0.45 | VIOLATED |

## Recommended action

**Reroute via illuminated ridge corridor**

Dominant factors:
- Safety: +0.309
- Science value: +0.150
- Energy efficiency: +0.148
- Reversibility: +0.138

Fallback trigger: Re-evaluate when a hard limit is approached or the confidence proxy falls below 0.55.
Valid until: Next decision checkpoint or on any hard-constraint threshold crossing.

## Simulation

- Run: `eb23153e-d8ee-4da9-840a-998c3e0d96af` model `rover-twin-v1` seed 42
- Validation: warn, 61 steps, 2 warnings

## Terrain

- Tile `south-pole-shackleton-degerlache-001` (LUNAR_POLAR_STEREO_SOUTH, 20.0 m/px), synthetic=True
- Elevation -511..718 m, PSR proxy 52%

## Source health

- LRO LOLA — Lunar Digital Elevation Model: **unavailable** (fallback)
- LRO Diviner — Lunar Radiometer surface temperature: **unavailable** (fallback)
- LRO LROC — imagery products: **unavailable** (fallback)
- NAIF SPICE — Sun/Earth/Moon geometry & frames: **unavailable** (fallback)
- JPL Horizons — ephemerides: **degraded** (fallback)
- ESA Planetary Science Archive: **unavailable** (fallback)
- Local development fixtures: **unavailable**

## Limitations

- Terrain elevation is a SYNTHETIC development fixture (not a LOLA measurement); replace via scripts/fetch_lola_sample.py.
- Thermal/illumination are geometry-based approximations, not Diviner measurements or SPICE-derived.
- Rover twin is a generic educational model, not a specific ESA vehicle.
- 'confidence_proxy' is a heuristic, uncalibrated score (see docs/08-decision-intelligence/confidence-policy.md).
- No ESA endorsement is implied.

## Software versions

- data_platform: 0.1.0
- terrain_pipeline: terrain-pipeline-v1
- rover_twin: rover-twin-v1
