Audit trail — hash, log, inspect

A contract document gets a SHA-256 fingerprint for the audit trail, the event is logged at info level, and Inspect shows the full envelope mid-flow (open it while stepping a debug run).

What’s inside

5 nodes — every type links to its full reference page.

Step	Node	Type
Signed contract	Inject	`input.inject`
Fingerprint	Crypto	`utility.crypto`
Audit log	Log	`utility.log`
Inspect	Visualize	`utility.inspect`
Audit line	Console	`utility.console`

Import it

Studio → Import — paste the JSON below (or the URL /docs/templates/audit-trail-hash-log-inspect.json).

Or ask the AI Copilot with the JSON pasted after the phrase:

import this workflow json into a new workflow named "Audit trail — hash, log, inspect"

Any credentials the nodes need are ${credential.…} references — add them once in Admin → Credentials and the template picks them up. Nothing secret ships in a template.
