## Evidence Tiers
|
|
|
|
### Tier 1 — Verified
|
|
Direct observation, owner-confirmed, or instrument-backed.
|
|
|
|
Sources include:
|
|
- Business owner confirmation
|
|
- Direct observation (photograph, instrument reading)
|
|
- Owner-provided documentation
|
|
|
|
### Tier 2 — Corroborated
|
|
Confirmed by independent sources.
|
|
|
|
Sources must be independent. Multiple extractions from the same website are `same_origin`, not independent.
|
|
|
|
Independent examples:
|
|
- Website schema + Google Maps listing (different data pipelines)
|
|
- Owner confirmation + website schema
|
|
|
|
### Tier 3 — Indicative
|
|
Single source, probabilistic, or directional.
|
|
|
|
Includes:
|
|
- Single website scrape
|
|
- Third-party listing (Yelp, Foursquare)
|
|
- AI model inference without citation
|
|

## Source Independence
|
|
|
|
Two sources count as independent only if:
|
|
- They originate from different data pipelines, or
|
|
- One is owner-confirmed
|
|
|
|
Sources deriving from the same business input (e.g., website footer, schema, booking page) are `same_origin`.

## Freshness Windows
|
|
|
|
| Domain | Window | Auto-stale trigger |
|
|
|---|---|---|
|
|
| Regular fields | 30 days | Not rechecked within window |
|
|
| Hours | 7 days | Holiday periods, seasonal changes |
|
|
| Pricing/Services | 14 days | Owner notification or observed change |
|
|
| Booking | 7 days | Link broken or provider changed |
|
|
|
|
A field transitions to `stale` when its freshness window expires without re-verification. A field transitions to `disputed` when two independent sources contradict.

## Liability and Action Risk
|
|
|
|
| action_risk | Agent behavior |
|
|
|---|---|
|
|
| low | Informational display |
|
|
| medium | Provide with timestamp and recheck notice |
|
|
| high | Display only; do not support transaction |
|
|
|
|
GeoLocal and downstream systems are not liable for actions taken based on stale data. Transactional guarantee requires real-time re-check.
