CFCR STAGE-1 TECHNICAL SUMMARY

What CFCR is
------------
The Continuum Fuel Cell Regulator (CFCR) is a deterministic supervisory control,
diagnostics, and evidence architecture for hydrogen electrochemical systems, including
PEM fuel cells and electrolyzers.

CFCR is designed to run as an overlay supervisory layer alongside an existing controller
architecture. It can begin in passive observer mode with zero actuator authority before
any advisory-envelope or full-authority deployment is considered.

What CFCR is not
----------------
CFCR is not a hydrogen-production method, chemistry, catalyst, reformer, energy-source
breakthrough, or excess-energy claim.

Core architecture
-----------------
CFCR unifies four functions that are often separate in industrial systems:

  1. Bounded interval supervisory control.
  2. Sensorless state estimation from standard stack signals.
  3. Closed operating outcomes: ACCEPT / DERATE / REFUSE.
  4. Cryptographic interval receipts tied to control decisions.

The differentiator is not merely "control plus logging." The same interval that evaluates
state and constraints also produces the tamper-evident evidence of the decision.

Commercial relevance
--------------------
CFCR is intended to support:
  - stack-protection and transient envelope governance;
  - hidden-state visibility for hydration, flooding risk, and degradation;
  - warranty and insurance review;
  - fleet analytics;
  - electrolyzer production-record integrity;
  - compliance/MRV-style evidence workflows.
