{"version":"1.0","status":"Public draft","published":"2026-09-30","principle":"An agent is sovereign when it is owned and controlled by the person it serves, not by the platform that hosts it. AOH certifies outcomes the owner can observe and demonstrate, never intent or architecture.","rules":["All six criteria are required. There is no partial certification: the criteria are individually necessary and jointly sufficient.","The criteria measure conditions for ownership and control. A failed test shows that a requirement is unmet, not that an agent or its maker has divided loyalties. A high score does not establish that an agent is trustworthy in every sense, or free of influence through its underlying model.","We evaluate what the owner can do with, see in and verify about the agent, not the quality of the model or what the agent is used for. Format and architecture are evidence, not criteria.","Each criterion carries a 'does not require' clause. The bar is effective ownership, not perfection.","Criteria describe outcomes, never mechanisms. Any design that achieves the outcome passes. Examples and 'how to pass' bullets show ways to meet a test; they are not requirements.","One outcome, one test. Each owner outcome and each fact is graded by exactly one test (G8), so equal criterion weights do not double-count anything.","Sovereignty covers both the exit and the stay. A vendor may offer only its own models and services while hosted, but it may not change, steer, mine or withhold the agent against the owner's will, and the owner must be able to leave at any time.","Substantial modifications of a certified format or runtime (anything that changes a test outcome) trigger re-certification, whatever the vendor calls the release.","Every assessment records the criteria version it was scored against. Scores are comparable only within the same version.","Definitions. Owner: the person or organisation that acquires and administers the agent. Evaluations take the view of a one-person business, where the owner is also the administrator and the only user. A member using an agent their organisation provisions is a delegate of the owner, not the owner. Provider: whoever makes, distributes or hosts the agent, other than the owner. Runtime: the program that executes the agent. Agent: everything that defines this owner's agent (configuration, instructions and logic, memory, action record, schedules, files, identity, credentials)."],"scoring":{"statuses":{"pass":{"value":1,"label":"Pass","meaning":"The test's pass definition is met, supported by public documentation, binding terms, source code, or reproducible observation."},"partial":{"value":0.5,"label":"Partial","meaning":"The test's partial definition is met, or a grading rule caps the test at partial."},"fail":{"value":0,"label":"Fail","meaning":"The test's fail definition is met, or the architecture structurally prevents the outcome."},"unknown":{"value":0,"label":"Unverified","meaning":"Insufficient public evidence. Scored as zero; treated as unmet until demonstrated."}},"gradingRules":["G1 Grade against the test's own pass / partial / fail definitions. Where a test lists shortfalls, none is a pass, one is a partial, two or more is a fail. Where a test has no shortfall list, meeting several partial conditions stays partial unless the fail definition is met.","G2 Basis. Tests marked basis 'default' are graded on the out-of-box configuration of the evaluated product. Tests marked 'achievable' are graded on what the owner can set up with first-party, documented means.","G3 Normal interface. An owner right must be exercisable through documented, supported means that need no programming. The product's UI, its documented CLI, and documented human-readable config or instruction files all count. A right exercisable only by editing source code, running database queries, using undocumented internals or installing a third-party extension scores at most partial.","G4 No gatekeeping. A right available only on some paid tiers or behind a licence key scores at most partial. A right that needs case-by-case provider approval, review or a support ticket fails.","G5 Provider-independence tests (P3, P4, A2, V1, V2) are graded assuming the provider is hostile, unreachable or defunct; a pass must hold in all three cases. P1 and P2 are graded with a cooperative provider; exit when the provider is hostile or gone is graded only in P5.","G6 Evidence. A pass needs source, configuration, reproducible observation, or a binding public commitment (terms, policy, contract) for hosted components that cannot be inspected. A commitment is binding only if the provider cannot change it without advance notice and the owner can exit under the old terms first; otherwise it supports at most partial. Marketing or blog statements support at most partial. Disclosure or consent that is less prominent than the practice it covers does not count. Where a technical capability contradicts a promise, the capability wins.","G7 Scope. Grade the whole agent as offered, including cloud components that are on by default or required. Local-only credit applies only when the cloud component is optional and off by default.","G8 One fact, one test. A fact is graded only in the test that owns it. Owners: usability of the exit route in P1; export completeness and re-linking of integrations in P2; right to run and kill paths with the provider blocked in P3; capability loss caused by the model in P4 (loss of a provider service is P3); exit after termination in P5; readability of agent state in T1; visibility of context and settings in T2; what the provider holds outside agent memory, and retention periods, in T3; self-benefiting influence in T4; action-record completeness in A1; source availability and the source-to-binary link in V1; attribution of state changes (including memory provenance and override records) in V3; memory the agent uses (including profiles) in M2; adding and removing tools in M3; provider-initiated changes to the agent, including remote flags and model retirement, in M5; every scope and limit, including the agent changing its own controls, in C1; data flows, secondary use, staff or legal access and changes to data terms in C4; credential visibility and revocation in C5; erasure of the whole agent in C6. Findings may mention a fact owned by another test but must not grade it.","G9 An owner's deliberate, recorded choice to switch off a protection (M4) never fails another test. Tests are graded on what the owner can have, not on what the owner chose to turn off.","G10 Evaluated offering. Each evaluation grades one declared offering (product, plan and deployment mode), recorded in versionNote. Choose an offering a one-person business can buy or install on its own; plans sold only to larger organisations are out of scope. Basis 'default' means what a new owner gets after install or signup. A mode counts toward 'achievable' only if it is documented and supported; a mode behind an 'experimental' or unsupported flag scores at most partial. When first-run setup asks the owner to choose (for example between a provider-hosted service and their own key), the default is the option the setup preselects or recommends; if none is preselected or recommended, it is the option listed first.","G11 Absent capabilities. A dimension of a test that the agent cannot act on at all (for example spend for an agent that cannot pay) counts as met, and the evaluation must record that it was treated so. There is no n/a status.","G12 Missing evidence. The burden of proof is on the provider. When a pass condition or a shortfall depends on something public evidence does not settle, treat it as not met: count the shortfall as present, or withhold the pass.
