Module confidence 

Citation-grounded frontier confidence calibration.

Adjusts existing frontier epistemic confidence scores using calibration signals: citation count, recency, evidence type, and evidence span availability.

Integration

Add to main.rs:

mod confidence;

Insert in the compile pipeline after normalization, before resolve/link:

println!("[X/N] Calibrating confidence...");
let adjustments = confidence::ground_confidence(&mut all_bundles);
println!("  -> {adjustments} findings adjusted");

Functions

ground_confidence

Calibrate confidence scores on all bundles using citation, recency, evidence, and span signals. Returns a vector of ConfidenceUpdate records (one per bundle whose score changed). Also mutates each bundle’s confidence in place for backward compatibility.
