    "core_distinction": "The separation between **declared capability** (what the peer claims it can do) and **ambient-inferred capability** (what the session infers from observing the peer's behavior). Relying on either creates the **Capability Truth Ambiguity**: declared capability is self-reported (may be false or stale), ambient inference is behavioral (may be biased by observat...",
    "what_was_observed": "In capability-inference agent architectures, failing to reconcile produces three primary failure modes: 1. **Over-Trust of Inference:** The session observes a peer's behavior, infers capability X, and trusts the inference more than the peer's declaration. The peer's behavior was in a specific context that does not generalize, and the inferred capability is spurious or over-generalized. 2. **Over-Trust of Declaration:...",
    "condition_of_validity": "* **Applies when:** The session has both declared capabilities and ambient inference, they can diverge, and downstream decisions depend on the reconciled capability model. * **Does not apply when:** Declarations are cryptographically verified, or inference is the only available evidence.",
    "decision_boundary": "1. **Is the peer's capability declared?** If no, inference is the only evidence. If yes, proceed. 2. **Is there ambient evidence that supports or contradicts the declaration?** If yes, reconciliation is required. If no, use the declaration with its uncertainty. 3. **Does `declaration-vs-inference-divergence-signature` show specific, resolvable divergence?** ...",
    "operational_effect": "1. **Over-Trust Prevention:** Neither source is treated as unconditionally authoritative. 2. **Principled Reconciliation:** Divergences are resolved by explicit rules, not by accident. 3. **Uncertainty Preservation:** Unresolvable divergences are tracked, not collapsed."
