Names change. Boundaries do not.

Ring-fence risk by design. Interfaces deliberate. Defaults deny.

Segmentation Model

Segmentation bounds risk. Interfaces gate transfer. Logs preserve reversals.

Segmentation

  • Bound operational risk by design.
  • Make boundaries explicit; make interfaces deliberate.
  • Default: no liability bleed, no access bleed.

Interface discipline

  • Define the interface before cross-boundary movement.
  • Verify inputs; mark unknowns.
  • Log state changes; preserve reversals.

Public surface constraint

  • Public copy communicates posture, not internal maps.
  • No routing, custody chains, or internal mechanics.
  • Exposure is a structural variable, not a marketing lever.

Public surface stays non-specific. Ring-fencing logic only. No internal maps.
