neoprint.lifecycle()

Create a lifecycle manager for fingerprint drift tracking and auto-linking.

Signature

function lifecycle(): LifecycleManager

LifecycleManager Methods

record(fp)

Record a fingerprint snapshot for drift tracking.

const lc = neoprint.lifecycle()
const fp = await neoprint.get()
lc.record(fp)

link(fp)

Attempt to link a new fingerprint to a previously recorded one.

const link = lc.link(newFp)

Returns:

interface LifecycleLink {
  linkedTo: string | null        // previous fingerprint ID
  probability: number            // 0–1
  driftedSignals: string[]       // what changed
  stableSignals: string[]        // what stayed
  predictedNextDrift: string[]   // likely to change next
  decayRate: number              // changes per day
}

getStabilityReport()

Per-signal stability analysis over time.

const report = lc.getStabilityReport()
// { canvas: { driftCount: 3, stability: 0.85 }, ... }

clear()

Delete all stored lifecycle data.
