From collection to evidence

Read. Redact. Record.

Discovery reads supported local evidence without running discovered AI tools. Sensitive values are removed before the evidence is built.

01

Collect

Read approved device and AI configuration signals.

02

Build evidence

Keep the source and relevant context. Remove sensitive values.

03

Save locally

Write evidence before attempting delivery.

04

Report

Send through an encrypted outbound route to the platform.

Collection boundaries

The fact, without the secret.

Discovery and request enforcement are separate capabilities. Supported enforcement may inspect a request locally; this directory describes discovery signals.

01

Credential presence

Report that a key exists and the relevant configuration context, without reporting its secret value.

02

Repository context

Identify supported project and repository metadata. Source-code contents are not required for this discovery.

03

Content off by default

Prompts, responses and transcripts require an explicit administrator-controlled collection choice.

Missing evidence stays unknown.

A failed check does not become a pass. A rule that is off stays ungraded; a control that does not apply remains distinct.
