Abstract:
The Apple-Siri interoperability debate under the EU Digital Markets
Act exposes a difficult technical question: how can third-party AI
assistants gain meaningful access to device functions without forcing
the platform to surrender privacy, security, or control over
consequential actions?
The DMA can require AI interoperability, but interoperability alone
does not determine when a third-party AI is authorized to cause a
real-world effect. The architecture described in this document
addresses that missing execution-finality boundary.
This document proposes an execution-finality architecture in which an
AI assistant may request an action, but the request itself has no
power to make that action effective. Each consequential operation
remains in a Non-Effective State until protected infrastructure
validates the requester, resource, destination, user intent where
required, freshness, revocation state, and policy conditions.
Only then is narrowly scoped, non-bearer execution authority created.
At the Finality Sink—the first boundary where the action can become
externally effective—the system independently verifies that the real
operation still matches what was authorized. Any mismatch, replay,
substitution, expiry, or revocation causes fail-closed denial.
The key principle is simple: interoperability should grant
participation, not uncontrolled execution authority.
This offers a possible technical approach to the interoperability-
security problem: third-party assistants could participate
meaningfully without requiring broad reusable permissions, while
platforms retain privacy, security, revocation, anti-replay, and
final-effect controls.
Execution-Finality Governance therefore reframes the problem from
closed versus open to open participation with bounded, verifiable
authority.
