The smallest non-inferior representation was ordinary causal prose: say who can prove what, who owns the meaning, what changed in reality, and what the evidence does not prove.

The problem was not missing terminology

Imagine explaining a failed deployment to a new Agent. You could hand it a typed graph containing every relation between source, execution, receipt, Task, provider, and external effect. Or you could say:

The command ran locally. That proves local execution. It does not prove the external service changed. Check the external owner before treating the deployment as current.

Both descriptions can be correct. The research question was whether the richer representation actually helps the Agent make the right next decision.

This mattered because Ordivon had accumulated many useful distinctions—authority, persistence, currentness, capability, consequence, selection, recovery. A project can become difficult to understand when every distinction is promoted into a mandatory schema or vocabulary.

We froze the test before asking the model

EX3–EX7 preregistered seventeen owner-native responsibility families and five independent test surfaces before the live Provider calls. Later stages were not allowed to rewrite the correct actions to fit earlier results.

The program compared several representations:

  • compact causal prose — the minimum owner-native explanation;
  • causal cards — a more explicit structured summary;
  • typed relations — formal relations such as proof, persistence, and non-implication;
  • seven-question grammar — an explicit diagnostic checklist;
  • four-question grammar — a shorter checklist tested on the final untouched surface.

The primary outcome was not whether the prose sounded elegant. It was whether the Agent selected the exact frozen action.

Every representation hit the same ceiling

Across EX3–EX7, the accepted semantic decisions totaled 1,326 / 1,326 exact actions. That creates an important limitation—the task was easy enough for all retained treatments to reach the ceiling—but it also makes the cost comparison clean.

Four questions102 / 10277,536+12.90%

The preregistered rule was to choose the smallest representation that was not worse on the action outcome. Compact prose won mechanically.

What compact prose actually means

Compact does not mean vague. A useful explanation still names the distinctions that change the next action.

For Ordivon, that usually means answering only the relevant subset of these questions:

  1. What happened?
  2. Who can prove it?
  3. Who decides what it means?
  4. What state must survive interruption?
  5. Who merely carried or executed the work?
  6. What does the evidence not prove?
  7. What would break if this distinction were removed?

The experiment did not support injecting this checklist into every Agent turn. The checklist remains a debugging method. Once the boundary is understood, it should be compressed back into normal language.

Negative statements did most of the work

Many of the most transferable explanations were simple non-implications:

execution ≠ consequencepersistence ≠ ownershipRun completion ≠ Task completionhistory ≠ currentnesscapability ≠ authorityexposure ≠ understanding

These statements are valuable because they stop one layer from claiming more than its evidence can support. They also translate well across Finance, Security, Game, Studio, World, Host, Harness, and Runtime without requiring every project to share one object model.

What this changes on the public site

Ordivon Web now treats formal vocabulary as the third layer of explanation, not the first:

concrete situation
→ one-sentence causal distinction
→ smallest mechanism
→ exact evidence
→ formal term when useful
→ what the result does not imply

This is also consistent with Studio R4–R6. More features did not automatically produce more understanding; evidence-addressed propositions were more stable than fine labels; and the real encounter mattered more than source structure alone.

What this does not prove

The experiment does not show that diagrams, schemas, relation types, or checklists are useless. They remain valuable for implementation, evidence design, debugging, and hard cases. It shows something narrower: on these bounded Agent decision surfaces, making the explanation structurally richer did not improve the action.

It also says nothing direct about human readers. A person may benefit from a diagram, progressive disclosure, animation, or a different reveal order. Those are human-facing expression questions and need their own evidence.

A good explanation is not the one that contains the whole system. It is the one that leaves the reader with exactly the distinctions required to make the next correct judgment.
