Institutional execution cannot depend on a single valid thing. A valid signature is not enough, a valid proof is not enough, and a valid software artifact is not enough. immo.quick Serverless Edition is built around a layered security model in which cryptographic validity, contextual validity, relational validity, authoritative state validity and collective state coherence must close together before a critical execution path can become possible.
The result is a security architecture designed to prevent trust from concentrating in one algorithm, one signing root, one proof, one build artifact, one compute instance, one witness or one threshold participant. The architecture remains fully serverless and hardware-independent: hardware may execute cryptographic operations, but hardware does not create authority and no HSM, TEE or proprietary hardware root is required to define system trust.
Cryptographic validity is necessary. Contextual validity is necessary. Relational validity is necessary. Authoritative state validity is necessary. None is sufficient alone.
Post-quantum cryptography is already integrated into the execution and evidence architecture rather than being treated as a future migration note. Algorithm lifecycle and cryptographic policy transitions remain versioned so that cryptographic change can be introduced without rewriting historical evidence.
The public claim is deliberately precise: the system is designed to reduce dependence on any single cryptographic assumption and to preserve evidence continuity across cryptographic policy transitions. immo.quick does not claim that a complete software system is ‘unbreakable’ or that post-quantum primitives eliminate every implementation, execution-state, authority or supply-chain risk.
The current baseline has been subjected to compound adversarial regression scenarios covering proof and build substitution, distributed-state manipulation, threshold-context poisoning, authority-scope misuse, participant-set drift, witness split-brain and stale capability binding.
Security findings are not deleted from the architecture history. A discovered collective-state weakness in the MPC reconstruction path was retained as a permanent finding, remediated, converted into a broader system invariant and bound to regression verification. That policy is intentional: security maturity is better demonstrated by preserved findings, proven remediation and repeatable regression than by a claim that no weakness has ever existed.
The baseline binds the required cryptographic, proof, build, deployment, distributed-execution, threshold-computation, adversarial-test and remediation state into a versioned security reference. After sealing, a security-critical change is either identical to the baseline or must appear as a new authorized and provable state.
