Controller record (CIR)
A live controller identification record: who is accountable, the declared purposes, and the legal basis, resolvable as a did:web controller ID.
0PN Lab Sandbox · Digital Transparency Infrastructure
Stand up a Transparency-by-Default baseline, trigger a notice receipt, and verify it against our reference implementation. Real artefacts, no intake form, no obligation. Controller-ID-first, standards-grounded, hash-verifiable.
Access is gated to start. Every request is acknowledged with a notice receipt, the on-ramp practices what it sells.
Not assertions. Running, hash-verifiable artefacts you can open, exercise, and check.
A live controller identification record: who is accountable, the declared purposes, and the legal basis, resolvable as a did:web controller ID.
Trigger a notice and receive a standards-conformant receipt with an ID tied to the notice version. Evidence the notice happened, not a claim that it did.
Inspect the notice event log: hash-linked entries where each record commits to the one before it. Confirm for yourself the sequence cannot be silently altered.
A Transparency Performance Indicator reading with per-criterion findings, not one opaque grade. Re-runnable, so it can be benchmarked over time.
A sanitised reference example: a consent record flowing to an inference-disclosure event, the evidence that even the processor cannot read the principal's data.
Once you have access, run a read-only TPI-R capture against a domain you control and read the findings against the same criteria.
Tell us who you are and a domain you care about. We acknowledge the request with a notice receipt for the email you share, the gate itself demonstrates the product.
Open the controller record, trigger a notice, read the receipt, and verify the NEL chain is tamper-evident. See the actual outputs.
Run a read-only measurement against a domain you control and get per-criterion TPI-R findings.
If it is useful, we send a scoping outline within five working days for the package that matches what you need. No obligation.
Gated to start. Free. No obligation. We acknowledge every request with a notice receipt.
Provisional receipt:
Your email client will open with the request prefilled, send it and we will respond within five working days. If nothing opened, email hello@0pnlab.com directly.
