Rejected design alternatives

These are intentionally rejected to prevent future regressions.

• VDB-style CRUD APIs: rejected; bijux-vex is an execution engine, not storage. Silent persistence semantics would dilute contracts.
• Implicit retries on invariants: rejected; invariants are terminal programmer/system faults. Retrying hides bugs and corrupts provenance.
• Silent ND fallback to deterministic: rejected; violates declared contracts. ND without ANN must fail explicitly.
• Hidden randomness: rejected; all randomness must be declared via RandomnessProfile and audited.
• Adaptive schema drift: rejected; OpenAPI/ABI changes require additive evolution or version bumps, never silent drift.
