Evidence handling controls
Immutable source policy
Source evidence is retained as original material and not mutated in-place.
Deterministic processing
Processing stages are deterministic and verifiable from known inputs.
Hash verification
SHA-256 hashes are used to verify source and derivative integrity.
Audit and oversight posture
Append-only event logs
Access, transform, and export activity is retained as durable audit events.
Role-aware access boundaries
Workspace capabilities are restricted by authenticated role and subscription scope.
Export reproducibility
Export bundles include manifest artifacts required for independent checks.
Federal Rules of Evidence alignment
Evident ICU produces the technical artifacts commonly required when evidence is offered in court. Admissibility is determined by the court; the platform supplies the foundation.
- FRE 901 — Authentication: SHA-256 hashes at intake, derivative hashes at each pipeline stage, and a signed, append-only custody ledger give the proponent the record needed to show the item is what it is claimed to be.
- FRE 902(13)–(14) — Self-authenticating electronic records: Exports include hash manifests and a certificate-of-process summary suitable for a qualified-person declaration under the 2017 amendments.
- FRE 1001–1002 — Originals and duplicates: Originals are retained immutably; exported duplicates are byte-for-byte or documented derivatives with hash provenance back to the original.
- Rule 26 / 34 — Discovery production: Export bundles carry a load file, Bates ranges, family grouping, and a manifest suitable for opposing-counsel production.
