Why not just logs?

Logs tell operators what happened. Tenbri gives anyone, including someone who does not trust the operator, proof of what an agent decided and why.

	Application logs	Tenbri
Integrity	Editable, rotated, deleted	Hash-chained and signed; any change fails verification
Who acted	A shared service account	The specific agent, person or service, with its own key
What it saw	Free text, if anything	Inputs pinned by reference, version and content hash
Why it was allowed	Rarely recorded	The rule or grant that allowed or refused it
Human oversight	A Slack thread, if anything	The approval, as its own signed entry
Timing	After the fact	The intent before the action, the outcome after
Sharing with an auditor	Give them access to your systems	A receipt that verifies on its own, offline
Personal data	Copied into log lines	Only hashes in the chain; bodies encrypted and erasable

Tenbri does not replace logs, traces or observability tools: it records decisions and links to the trace that produced them (OpenTelemetry trace and span ids).
