Data-source register

Know the evidence boundary.

CarGlitch should identify the source category behind a result without implying that a source observes more than it does. This page describes the consumer-facing standard; it does not claim that production feeds are connected.

Demonstration status: The example record on this page uses synthetic demonstration data only, fixed as of 2026-08-15. No manufacturer imagery or proprietary manufacturer assets are used.

Source map

What each category can tell us

Category description · no live feed claimed

Marketplace listings

Describe asking prices, vehicle configuration, mileage, location, and listing timing when supplied.

Observed
Advertised offers during a stated observation window.
Not observed
Final transaction price, undisclosed fees, negotiation, or vehicle condition beyond supplied fields.
Category description · no live feed claimed

Transaction records

Can describe completed sales where lawful, licensed, and sufficiently documented.

Observed
Only the transaction fields and coverage explicitly cited for a result.
Not observed
A complete census of private sales or every component of out-the-door cost.
Category description · no live feed claimed

Repair and reliability records

Can surface fleet-level patterns within the reporting system that produced the records.

Observed
Reported repair events for covered vehicles and participating channels.
Not observed
Unreported repairs, causal failure mechanisms, or the future of one vehicle.
Category description · no live feed claimed

Vehicle configuration references

Support consistent make, model, model-year, trim, drivetrain, and powertrain labels.

Observed
The attributes present in a cited reference and matched with sufficient specificity.
Not observed
Installed options, modifications, condition, or history that the source does not encode.

What accompanies an estimate

  1. IdentityNamed citation and publisher, with verification status.
  2. TimeObservation window and as-of date, kept distinct.
  3. PopulationSample count and unit, never a count without context.
  4. MethodModel name and version when a model shaped the result.
  5. UncertaintyConfidence rationale and interval where supportable.
  6. LimitsProminent flags for coverage, inference, and missingness.

Inspectable example

A source record should open up.

This fixture demonstrates placement and failure language. Every automotive number inside is fabricated and labeled synthetic.

Synthetic demonstration confidence — not a market finding.

Confidence: Moderate184 synthetic fabricated listings · fixed as of 2026-08-15

Demonstrates a middle grade where configuration coverage and sample breadth constrain precision.

Synthetic demonstration count; not collected listings.

Confidence describes support in the available observations. It is not the probability that a specific vehicle or price is “correct.”

Missingness policy

No source means no verified claim.

Unavailable fields remain unavailable. Absence is not converted to zero, average, “no issues,” verified, or current. If a future production source has licensing or redistribution constraints, the interface should cite it to the extent permitted and plainly describe those constraints without republishing restricted material.
