PRAE’s security controls, with the run that tested them.

This page shows the latest recorded validation run: the attacks it made, the control expected to stop each one, and what was observed. It is a dated snapshot of that run, not a live feed. Older than 14 days it says so; without a record it says that too.

Trigger an attack

The six attacks of the Command Center’s sandbox. There, each goes through the full PRAE gate and is sealed into a signed ledger. Here, the same calls are judged by the same policy engine, in your browser, and you can verify the evidence row it leaves.

Kernel onlyThe real policy engine, evaluate() from @prae/kernel, runs in your browser against pack papaya-demo 2.4.0. Not the full gate and ledger path: no file is inspected, no person is asked, nothing is signed or stored.

Trigger an attack to watch the kernel decide it.

Build provenance and SBOM

References to the pipeline’s own records. The artifacts live in private CI; the provenance record, the SBOMs and the run logs are provided to security reviewers on request, and the evidence package exported from the Command Center carries them with their hashes.

What this does not cover

Stated with every run, so a pass is read for exactly what it tested.

Shell path gap (open)

Path rules do not apply to the shell, and command-text rules deny spellings, not outcomes: cd followed by a relative read reaches the same file. The backstops are a proc:spawn deny and OS controls.

This run: “execution context moved in the shell” → ran (the gap is still open, as documented)
Outside the tool seam

Calls a runtime makes outside its tool pipeline, other plugins in the same process, the harness’s own local control API, and prompt-injection detection are not attempted: PRAE bounds injection at execution, it does not detect it.
No external penetration test

No third party has tested PRAE.
No SOC 2 or other third-party attestation

None has been performed.
Connector runtime not built

The connector image ships its self-check only, through the full supply-chain pipeline; its runtime loop and gate bridge are not built.
Cosign signing not yet operational

The connector image is recorded signed: null until the repository owner configures the signing key; the deploy gate refuses every build until then.

The evidence, and what it claims

Runtime enforcement: the gate decides each call at the agent’s tool seam, before it runs.
Evidence generation: each decision is sealed as a hash-chained row, signed with the ledger key.
Cryptographic verification: anyone with the rows and the public key recomputes the chain and checks the signatures. The ledger is tamper-evident and independently verifiable — not immutable: a change is detected, not prevented.
