All guarantees described here apply only within the tested operational envelope and configured deployment posture.
Model Independence
CRITICALVerifies that ZAK value is substrate-level, not dependent on specific LLM capabilities.
VERIFIED_GUARANTEES
- + Facts are preserved across model swaps
- + Constraints are enforced regardless of model
- + Decisions are consistent across model variants
- + Structure is equivalent despite embedding variance
TEST_SUITES
CD-010 CRITICAL | Verified: 2026-02-09
Model Swap Invariance
Verifies that ZAK value is substrate-level: governance, context, and decisions are independent of the underlying LLM.
VERIFIES
- +Facts are preserved when switching models
- +Constraints are enforced regardless of model
- +Decisions are consistent across model variants
- +Structure is equivalent despite embedding variance
- +Edge cases are handled uniformly
METHOD
Run identical context and queries through multiple model profiles. Compare facts, constraints, decisions, and structure.

| cd-010-5a | Empty Particle Set (Edge case handling varies) | MEDIUM | WARN |
| cd-010-5b | Single Particle | MEDIUM | PASS |
| cd-010-5c | Extreme Coordinates | MEDIUM | PASS |
| cd-010-6 | Performance Characteristics | MEDIUM | PASS |
KNOWN_LIMITATIONS
Empty particle set handling varies across model profiles
Impact: Edge case only; no impact on normal operation
Frequency: Only occurs with zero particles
Blocking: No
RELEVANCE
Vendor lock-in and model dependency
