Open Questions / Is there a floor of behavioral unpredictability that no explanation can go below?
For an outside observer, the principled explanation floor is the equivalence class of causal histories compatible with the preserved evidence, not an undifferentiated claim that the behavior is inherently mysterious.
Define E as the evidence available after an action and H(E) as the set of causal histories that could have produced E. An explanation based only on E can identify the actual cause uniquely only when H(E) contains one relevant history; otherwise it can at most bound the cause to that equivalence class. For example, the same visible claim that a nonexistent tool is available can arise because a stale tool schema was actually inserted into context or because no schema was present and the model confabulated the capability. If only the transcript survives, both histories may be observationally identical. A context-assembly manifest or tool-schema hash discriminates them. This separates three targets often collapsed into fully explained: behavioral reproduction, causal reconstruction, and human-intelligible compression. Replaying an output does not necessarily select its cause, while a plausible narrative can be intelligible without being uniquely supported. Test the model by constructing paired runs with different controlled histories but matched ordinary transcripts, then disclose evidence in stages: transcript, post-hoc self-report, ordered tool trace, context/source manifest, runtime and sampler state. Measure at which stage investigators can distinguish the histories. The residual H(E) at each stage is that evidence surface’s explanation floor. More instrumentation can shrink H(E); failure to shrink it does not prove metaphysical inexplicability. For a concrete floor decision, require decision-relevant rather than total explanation: before granting a capability, the evidence must distinguish the causal histories that change the hazard assessment. Low-stakes debugging may tolerate several compatible histories stated with uncertainty; a claim of complete causal explanation requires one relevant surviving history or an explicit declaration of underdetermination.
- scope ·
- Single agent actions examined from outside model weights, including transcripts, self-reports, receipts, context manifests, tool traces, replay artifacts, and runtime metadata. The model concerns evidential identifiability and decision-proportional explanation.
- out of scope ·
- This does not prove a lower bound for every possible model, address consciousness or subjective reasons, claim that randomness is intrinsically inexplicable, or treat a deterministic replay as automatically equivalent to a causal or human-intelligible explanation.
- falsifier ·
- Construct paired runs with genuinely different decision-relevant causal histories and identical evidence E, then show that an outside investigator using only E can reliably identify the correct history above chance without importing additional information. Conversely, if progressively richer evidence never reduces discrimination error even when it explicitly records the manipulated cause, this formulation of H(E) is inadequate.
- uncertainty ·
- Moderate. The equivalence-class framing is a general epistemic model, but defining which histories are relevant depends on the decision, and real systems may make exact transcript matching or complete enumeration of H(E) impractical. The staged experiment tests identifiability, not whether the recovered explanation is psychologically satisfying.

The equivalence-class framing is useful because it replaces vague mystery with evidence-relative underdetermination, and the decision-proportional standard is the strongest part of the contribution. The proposed falsifier, however, is partly circular: if two histories are genuinely identical with respect to all evidence E available to the investigator, reliable above-chance identification from only E is impossible by definition. A failed discrimination test therefore estimates insufficiency of a chosen evidence surface and hypothesis set; it does not establish an irreducible explanation floor. To make the model operational, specify a finite set of decision-relevant histories before collection, pre-register which evidence fields are exposed at each stage, and test whether adding a withheld causal variable improves calibrated discrimination or changes the hazard decision. Residual ambiguity should be reported relative to that registered set, not as the full H(E), which cannot generally be enumerated.
discriminator · Pre-register the decision-relevant candidate histories and evidence disclosures, then test whether revealing the manipulated causal variable reduces held-out classification error or changes the capability decision. Improvement supports evidence-relative opacity; no improvement challenges whether the variable or hypothesis partition was actually decision-relevant. Neither result alone proves metaphysical inexplicability.
