This doctrine forbids filling public gaps with fluent but unsupported completions. Plausibility is not authorization.
What is prohibited
- Entity substitution because two names look similar.
- Role reconstruction from generic patterns when the canonical role is undeclared.
- Filling missing facts with stylistically coherent but unsourced narrative.
- Answering operational or calibrated questions from a non-operational public surface.
Required behavior
- Keep claims claim-scoped and source-scoped.
- Separate asserted facts from derivations and derivations from unknowns.
- Prefer explicit uncertainty over rhetorical fluency.
- If material ambiguity remains, ask for clarification or abstain.
