Readiness Forecasting

Status: Stable · Horizon: NEXT (promoted v0.5.0) · Priority: P1

Predict future readiness scores from current evaluation, local history, and time-based degradation heuristics.

CLI

spanda readiness forecast rover.sd
spanda readiness forecast rover.sd --target RoverV1
spanda readiness forecast rover.sd --horizon 14d --json
spanda readiness forecast rover.sd --all
spanda readiness forecast rover.sd --history .spanda/readiness-history.json

Types

• ReadinessPrediction — projected score at a horizon with risks
• ReadinessForecastReport — current score, degradation rate, and predictions
• ReadinessHistory / ReadinessForecast — from readiness-trends.md

Evaluates

• Current readiness (evaluate_readiness with simulation)
• Historical slope when .spanda/readiness-history.json has samples
• Heuristic degradation from readiness issues, safety coverage gaps, and factor weakness

Output

Per horizon: current → predicted score, degradation rate, projected risks, policy warnings (exit 1 when below minimum).

Integration

Extends spanda-readiness trends module; feeds scorecard and deployment gate signals. ML backends ship as spanda-readiness-ml package.
