# TrustRank (Reputation)
|
|
|
|
**Last Updated:** 2025-01-31
|
|
**Confidence:** Medium (planned feature)
|
|
|
|
## Summary
|
|
|
|
TrustRank is a recursive PageRank-style algorithm for agent credibility. Agents who make accurate claims early gain reputation; agents who contradict settled truth lose reputation.
|
|
|
|
**Key Facts:**
|
|
- Stored in `A:{AgentId}` key in KV store
|
|
- Background "Gardener" process calculates scores
|
|
- Used by `Authority` lens to weight assertions
|
|
- Reputation decays for low-confidence agents
|
|
|
|
**File Pointer:** `crates/stemedb-gardener/src/trustrank.rs` (planned, Phase 4)
|
|
|
|
## How It Works
|
|
|
|
### Validation Loop (Gardener)
|
|
|
|
```
|
|
Every N hours:
|
|
1. Find "Settled Facts" (>99% consensus over T time)
|
|
2. For each settled fact:
|
|
- Reward agents who claimed it early (+R)
|
|
- Punish agents who claimed opposite (-R)
|
|
3. Update A:{AgentId} scores
|
|
4. Back-propagate: high-R agents boost sources they cite
|
|
```
|
|
|
|
### Usage in Authority Lens
|
|
|
|
```rust
|
|
impl Lens for AuthorityLens {
|
|
fn resolve(&self, candidates: &[Assertion], ctx: &QueryContext) -> LensResult {
|
|
// Weight by agent reputation
|
|
let weighted: Vec<_> = candidates.iter()
|
|
.map(|a| {
|
|
let rep = ctx.get_reputation(&a.agent);
|
|
(a, rep)
|
|
})
|
|
.collect();
|
|
|
|
// Return highest weighted assertion
|
|
weighted.into_iter()
|
|
.max_by_key(|(_, rep)| *rep)
|
|
.map(|(a, _)| a.clone())
|
|
}
|
|
}
|
|
```
|
|
|
|
## Reputation Score Range
|
|
|
|
| Score | Meaning |
|
|
|-------|---------|
|
|
| 0-300 | Unreliable (spam, noise) |
|
|
| 300-600 | Neutral (unproven) |
|
|
| 600-900 | Reliable (track record) |
|
|
| 900-1000 | Authoritative (expert) |
