TESTED

The claim

a TypeScript verifier SDK re-checks the receipts without CAIN code and detects a tampered receipt

Level TESTED is how far the evidence goes: TESTED means a test suite exercised it, LIVE means it was observed on the hosted system. Nothing is claimed beyond its level.

Your browser downloads the bundle's SHA256SUMS manifest and the file(s) behind this page, hashes them with SHA-256 locally (WebCrypto), and compares. A match shows the record you are reading is the published one; it does not by itself prove who published it (see the signed claims registry and the bundle verifier for that).

Limitations of this bundle

• An integration library in one process; not hosted; not wired into the gateway, MCPGate or the clusters.
• Governance coverage outside the E25/E8 boundary is UNCONTROLLED or UNKNOWN (see COVERAGE_MAP.json); robots, vehicles, laboratories and physical actuators are UNENFORCED -- CAIN refuses to act there, it does not govern them.
• Perception VERIFIED means two independent registered sensor keys agreed; it says nothing about the physical truth of the reading.
• Injection detection in memory, perception and intent is a marker list; recall against real attacks is UNKNOWN.
• The self-improvement firewall governs the process; it cannot tell whether a promoted change is actually better or safe beyond the recorded stage evidence.
• Grid scenarios are distinct inputs over shared defences; the mutation self-test shows which defences they exercise.
• The TypeScript SDK is a verifier; agent-side TypeScript integration is not built.
• The research engine and frontier lab are registers only; no automated research feed runs.
• Scale rows are synthetic and in-process; the 100,000 row is a virtual model without signatures or E8.
• Hardware attestation UNKNOWN; zero-knowledge proofs NOT IMPLEMENTED; no external review.
