Explore preservation workflows
Follow a simulated workflow with exception branches, using no production data or backend calls.
A journey with exception paths
This synthetic simulation explains states; it creates no TSA tokens or ERS and calls no production service. Choose a scenario and advance step by step.
Each branch is a predefined explanatory sequence, not a backend test or real cryptographic evidence. These business-model labels do not introduce API enums.
READY
Sample package and independent checks
Reconcile a synthetic package with SHA-256 and distinguish integrity checking from ERS evidence.

Integration test plan
Success, duplicate, data-loss, TSA, webhook and handover tests with expected outcomes.
Read integration guide →Design a Trusted LTANS PoC
Prepare data, scope, acceptance criteria and a summary for your evaluation request.
View details →Check actual local bytes
Select a synthetic file and enter SHA-256 from a source you trust. The tool reads bytes locally without uploading; 10 MiB is this website tool’s limit, not an LTANS service limit.
