Cadence
Daily scheduled collection, packaging, and publication. Manual runs are possible, but the public stream is designed to grow one dated observation at a time.

What Cassandra observes
Cassandra collects public list-derived artifacts, normalizes them into comparable local records, and reports structural changes such as hash changes, service inventory shifts, or provider-service detail changes.
What EATF proves
The Evidence Attestation and Transparency Framework (EATF) binds the evidence package, payload, and declared hashes. It proves the observation package is intact, not that a provider is compliant or that a list has legal effect.
Why it matters
Governance systems often explain authority. Evidence systems explain what was seen, when it was seen, and exactly which bytes later readers can re-check.
Working lemma
Evidence is useful when it is bounded.
If E(t) = {S(t), D(t), R(t)} is a dated snapshot, diff, and receipt, Cassandra asks whether the receipt still binds the package bytes. It does not ask whether the public authority, court, auditor, or relying party should agree with the meaning of the change.

Plain-language reading guide
- Trusted list
- A public trust infrastructure artifact. Cassandra treats it as a source to observe, not as a verdict to issue.
- Structural diff
- A machine-readable description of what changed between saved observations.
- EATF receipt
- An Evidence Attestation and Transparency Framework receipt: a compact verification record for package integrity and declared hashes. See eatf.eu.
- Claim boundary
- The line between evidence integrity and legal, supervisory, or compliance interpretation.
