Signals (NormalizedSignals)

Raw data from providers (like Farcaster, Ethos, Talent Protocol) is normalized into a standard format before reaching the engine. The engine only understands these normalized signals.

Signal Providers

Provider	Primary Authority
Ethos	Long-term trust & credibility
Talent Protocol	Ability & skill (builder/creator)
Neynar	Social behavior & spam risk

These systems remain the source of truth for their respective domains. BaseCred does not generate a unified or proprietary score; scores are treated as raw inputs, normalized only for semantic comparison.

Normalized Signals

Normalized signals exist only at decision time and are not persisted.

interface NormalizedSignals {
  trust: Tier;           // from Ethos
  socialTrust: Tier;      // from Neynar
  builder: Capability;    // from Talent Protocol
  creator: Capability;    // from Talent Protocol
  recencyDays: number;   // freshness
  spamRisk: Tier;        // from Neynar
  signalCoverage: number; // 0–1, data completeness
}

Normalization Logic & Thresholds

Determined by src/engine/normalizers/.

Signal	Source	Logic / Thresholds
trust	Ethos	Based on credibility_score: • VERY_HIGH ≥ 1800 • HIGH ≥ 1250 • NEUTRAL ≥ 900 • LOW ≥ 550 • Else VERY_LOW
socialTrust	Neynar	Based on farcaster_user_score (0-1): • VERY_HIGH ≥ 0.85 • HIGH ≥ 0.6 • NEUTRAL ≥ 0.3 • LOW ≥ 0.15 • Else VERY_LOW
spamRisk	Neynar	Inverse of farcaster_user_score: • VERY_LOW (Safe) ≥ 0.7 • LOW ≥ 0.5 • NEUTRAL ≥ 0.3 • HIGH ≥ 0.15 • Else VERY_HIGH (Risky)
builder	Talent Protocol	Based on builder.score: • ELITE ≥ 220 • EXPERT ≥ 140 • BUILDER ≥ 60 • Else EXPLORER
creator	Talent Protocol	Based on creator.score: • ELITE ≥ 220 • EXPERT ≥ 140 • BUILDER ≥ 60 • Else EXPLORER

recencyDays is derived from last-activity timestamps. signalCoverage is the share of signals successfully fetched (0–1).
