Public audit trail
A reproducible record of the prices observed by SaaS Sentinel. The public ledger keeps one daily baseline per offer plus every evidence or rate transition; exact pre-partition checks remain recoverable in the internal audit archive.
History by GPU
Each model page is generated from the same deterministic observation ledger and only exists for GPU routes that already pass the activated model contract. Snapshot ranges describe daily baselines and distinct transitions; they are not a matched-cohort index or a capacity guarantee.

Market movement
These cards isolate actual normalized-rate changes from evidence-only refreshes so a source update is not mistaken for a price move.

Verified change log
A changed evidence hash can indicate a provider-page or source-payload update even when the normalized rate is unchanged. This rendered view is bounded to the latest 12 changes for a fast, reliable page; the complete append-only ledger remains available through the changes API and history JSONL.

Use history with current evidence
A human review reconciles the observed history with current quotes, capacity evidence, commitments and the costs outside the published GPU-hour rate.
Interpretation
Observed, not guaranteed
Each timestamp records what an approved source returned. It does not guarantee capacity, future price or an all-in invoice.
No fake freshness
An unchanged price is not presented as a new price. Source checks and price changes remain separate concepts.
Comparable unit
Rates are normalized to USD per GPU-hour. A USD series can move because a provider changed its native price, because an official reference exchange rate changed, or both; conversion-backed observations disclose the native price and ECB receipt separately. Storage, egress, taxes and support can remain outside the comparison.
