Fortress Baseline 1.0 is the sealed security reference state for the current immo.quick Serverless Edition architecture. It does not claim that the platform can never be attacked. Its purpose is more rigorous: it defines exactly which security conditions, evidence classes, regression tests and architectural invariants belong to the approved security state, and it requires future security-critical change to become a new authorized and provable state rather than silently replacing the old one.
The baseline was sealed after adversarial testing exposed not only expected failure paths but also a real collective-state weakness in threshold reconstruction. That finding was preserved, remediated, converted into permanent system rules and regression-verified. Fortress Baseline 1.0 therefore represents a security state that has been attacked, changed in response to evidence and then frozen as a new reference point.
A conventional security release often communicates a version number and a list of controls. Fortress Baseline 1.0 instead treats security itself as state. The approved state includes the relevant cryptographic policy, formal and deterministic assurance state, software supply-chain provenance, deployment-state evidence, distributed-execution policy, witness coherence rules, threshold-computation invariants, adversarial regression state and permanent security findings.
The internal proof contains detailed roots and bindings that are not published on the public website. Publicly, the important property is that the baseline is resolvable and versioned. Security-critical change is therefore not an informal edit to a running platform; it becomes a new state transition that must receive the appropriate authority, proof and regression evidence.
Fortress Baseline 1.0 is organized around a stricter execution condition than simple proof validation. Cryptographic validity is necessary. Contextual validity is necessary. Relational validity is necessary. Authoritative state validity is necessary. Collective state coherence is necessary. None is sufficient alone.
The rule applies across software proof, build provenance, distributed execution, witness attestations, capabilities and threshold computation. A technically authentic artifact remains unusable when its required relationship to the current state is invalid.
The baseline incorporates a permanent adversarial regression suite. The first compound class attacks source-to-execution continuity by combining implementation drift, stale proof material, deployment-state mismatch and distributed result manipulation. The second attacks threshold computation by mixing otherwise valid shares across sessions, share sets and authoritative states. The third combines valid credentials, witness signatures, participant-set mutation and stale capability binding to test whether individually authentic artifacts can be assembled into an invalid execution state.
These tests are not stored as historical notes. They are registered security artifacts with repeatable expected outcomes. A future platform state that reintroduces one of the tested failure classes is therefore not simply ‘a regression’; it fails a defined security baseline condition.
Fortress Baseline 1.0 retains identified security findings rather than removing them from the record after remediation. Each preserved finding can carry its affected version, observed behavior, root cause, remediation reference and regression-verification status. This establishes a security history that distinguishes between systems that merely claim maturity and systems that can demonstrate how weaknesses were discovered and closed.
The retained MPC collective-state finding is the first example of this policy. The initial reconstruction path allowed the state of one share to influence the collective reconstruction context. The corrected architecture requires explicit state coherence across all contributing artifacts before threshold closure. The broader lesson became a permanent meta-invariant: collective closure must never inherit state from a single member.
For institutional users, a sealed baseline creates a stable reference for technical due diligence and future change control. For auditors and regulators, it allows a security-critical execution path to be evaluated against a defined security state rather than against undocumented assumptions. For strategic partners and investors, it demonstrates that the platform’s moat is not a single cryptographic primitive but an interconnected architecture in which proof, context, build provenance, distributed state and historical evidence must remain coherent.
The baseline also establishes a clear disclosure boundary. Public materials explain the security properties and the existence of the sealed reference state. Detailed state-root composition, attack procedures, proof schemas, threshold topology and internal verification logic remain part of controlled technical disclosure.
Fortress Baseline 1.0 can be presented at different levels of technical depth. Public material explains the security model. Qualified institutional and regulatory reviewers can request a controlled architecture session, while the definitive baseline documentation and internal proof structure are reserved for NDA-governed review.
