Identity
Keep each evidence item tied to a stable record identity.
Evidence & accountability technology
DPAL turns project evidence into a reviewable history.
DPAL is VÖRSANN technology for evidence identity, provenance, traceability, chain of custody, integrity, history, review and controlled transparency. It does not replace independent verification, regulators or professional judgment.
Evidence
Identity + provenance
Source context remains attached to the record
Accountability
History + review
Changes and review state remain inspectable
What DPAL is for
Evidence that can be opened, traced and reviewed later.
DPAL is designed to keep an evidence item connected to its source, context, custody, integrity history and review state. A traceable record is not the same thing as a certified real-world outcome.
Provenance
Preserve source, time, place, method and revision context.
Custody
Record how evidence moves, changes and reaches an authorized reviewer.
Integrity
Use fingerprints and history to make later changes inspectable.
Review
Keep questions, approvals and review state attached to the record.
Controlled transparency
Show the appropriate evidence to the appropriate authorized audience.
Illustrative evidence flow
Capture context, bind identity, preserve history, then review.

Relationship to PDOS
Different purposes, connected records.
PDOS supports project lifecycle, work, decisions, readiness and reporting. DPAL focuses on evidence accountability and controlled transparency. PDOS remains evidence-first; DPAL is not a substitute name for PDOS and is not a registry.
