Anatomy of an evidence bundle
Not a clip. A file that can prove what it is.
An evidence bundle is the sealed package a property owner hands to your agency. A sealed package reaches an authority one of three ways: a secure link the business sends, behind a one-time code; an upload into the law enforcement agency's own evidence portal, such as Axon Evidence.com; or a release through the FusionTrace agency portal after the business approves the request. Every route is locked: encrypted, to the recipient the business chose, every look on the record. And on every route the package arrives sealed: each file carries a SHA-256 fingerprint and the whole package is digitally signed, so change one byte and the check fails. The recipient, and the prosecutor, defense and court the case brings in, verify it themselves, with no key from us.

Sealed at the source
The record is sealed the moment it is made, at the property, before anyone has a reason to want it changed. The seal is math, not a promise: a SHA-256 fingerprint on every file, and a digital signature on the whole package.
Provenance in the file
Who documented it, when, from which device, on which timeline. The answer to "where did this come from?" travels with the evidence instead of living in someone's memory.
Custody you can read
Every access is logged from the first view to the handoff to your agency. Shared links expire. The log is append-only, and it is in the bundle.
Verified with no key from us
You do not have to trust BlueWave, the property or the software. Recompute each file's SHA-256 fingerprint and compare it to the manifest, then check the digital signature. Change one byte and the check fails. The prosecutor, defense and court the case brings in can run the same check.
Built to be questioned
Admissibility is decided by the court. Provenance is decided by the record. A bundle is designed so that the second question has a clean answer before the first is ever asked.
The Standard
The FusionTrace Evidence Standard
The FusionTrace Evidence Standard is a public set of rules, free to read. It says how a business keeps, seals and shares its own incident record. The business that saw it, the officer who needs it and the court that weighs it all read the same file.
BlueWave wrote the Standard, and a foundation is being formed to steward it.
CaseTrace is the first product sealed to the FusionTrace Evidence Standard.
Law enforcement, counsel and the courts can check the seal independently on the Verify page at fusiontrace.io. The check runs in your browser against the published key of whoever sealed the package. Nothing is uploaded. The system never decides. Every determination is made by a person, 100% of the time.
The Standard's seal line reads: Sealed to the FusionTrace Evidence Standard.
