WattsProtect™ A²SC — The Proof Engine for AI Integrity

When an airplane crashes, investigators look for the black box.
WattsProtect™ A²SC is that — but alive.
It captures, verifies, and preserves every AI or machine action as verifiable truth — transforming black boxes into a proof engine.

🔹 The A²SC Chain of Custody

Trigger Detected — Events are captured in real time (calibration, model decision, policy change).
Policy Gate — Rules‑as‑code (OPA/Rego) verify compliance before execution.
Attestation Layer — Hardware and environment sign their integrity (TPM/TEE).
Hash‑Linked Logs — Each event connects cryptographically to the last.
Evidence Bundle — Data, policy, approvals, and signatures sealed as one record.
Immutable Vault — Write‑once storage ensures forensic permanence.

A²SC transforms uncertainty into evidence — a new covenant between intelligence and integrity.

🔧 Inside the A²SC Stack

Layer 1 — Event Capture: Sensor streams and system triggers ingested in real time. 🔹 First capture point of the Proof Fabric.

Layer 2 — Policy‑as‑Code: OPA/Rego enforces training, drift limits, and SoD at execution time. 🔹 Adds the first digital signature.

Layer 3 — Attestation: TPM/TEE verifies device & environment integrity; issues permit tokens. 🔹 Extends trust with hardware‑backed proof.

Layer 4 — Hash‑Chained Bundles: Events, policies, and signatures sealed into a linked evidence bundle. 🔹 Chain integrity: no silent edits.

Layer 5 — Immutable Vault: Write‑once encrypted retention; regulator‑ready retrieval. 🔹 Forensic permanence & exchange.

Each layer adds a signature; together they form the WattsProtect™ Proof Fabric.

🧭 Use‑Case Navigator

🔮 Predictive Calibration
Forecast drift, verify outcomes, and record both predicted & actual states — anticipatory compliance.

🏭 Manufacturing
Line‑level checks attested in real time; reduced scrap and downtime; instant audit artifacts.

🧪 Labs & Pharma
ISO / 21 CFR Part 11 traceability from live policy enforcement and signed evidence bundles.

🧠 AI Governance
Lineage for every inference; policy outcomes and attested runtime state, unified as evidence.

🛡️ Critical Infrastructure
Attested control changes only; hash‑chained telemetry; immutable vaults across sites.

🏥 Healthcare Devices
Clinical adjustments require verified training and MFA approvals; audit evidence on demand.
