Resolved in v0.4 (architecture and system design): - Reality grounding → §10.5 (Arbiter empirical checks) - Catastrophic forgetting → §11 (distributed architecture) - Cross-domain contradiction → §10.5 (Arbiter Agent) - Base model compatibility → §11 (independent submodel migration) - Adversarial confidence degradation → §10.5 (Arbiter gates all weight-affecting inputs) - Calibration pipeline scaling → §10.5 (Arbiter as first-stage sampler) - Evidence chain staleness → §10.5 (field-specific decay function, Class A–D) - Trust cold start → §7.1 (domain expertise from credentials on day one) - Sybil resistance → §7.2 (reputational accountability under attribution) - Router single point of failure → §10.9 (Raft-based HA cluster) - Arbiter bootstrapping → §10.5 (expert sampling calibration pipeline) - Personality-Arbiter feedback loop → §10.5 (adaptive sampling up to 15% detects over-correction before personality drift accumulates) - Curiosity gap bonus calibration → §10.5 (dual cap: per-gap ≤ K_natural_max; Case 3 collective ≤ 2/3 of exploration budget)

1. Subtle utility gaming
The 50% curiosity cap prevents overt gaming. A sufficiently capable agent might learn subtler strategies: slightly reframing familiar problems to appear novel, or selectively avoiding domains where its contradiction rate would rise. The curiosity gap bonus (§10.5, Case 3) partially mitigates this by directing exploration toward confirmed knowledge gaps — but the agent could still game gap detection by generating ambiguous outputs that trigger Case 3 without genuinely resolving the gap. Detecting subtle gaming requires an independent novelty measure, which reintroduces the circularity problem.
2. Multi-modal extension (partially resolved)
The framework assumes text throughout. Multi-modal extension decomposes differently for STEM vs. creative content.
STEM modalities — parse first, then run normal checks. Audio and video in STEM domains (a medical lecture recording, a documentary on how volcanoes erupt, a scientific journal audiobook) contains extractable factual claims. The strategy: transcribe and parse media into a structured claim set, then run the standard four-check Arbiter pipeline on those claims exactly as for text. Logical contradictions, mathematical errors, cross-session inconsistencies, and empirical verifiability all apply to factual statements regardless of medium. The hard problem is the parser, not the checker — once claims are extracted, existing infrastructure handles them.
Creative modalities — augmented by domain-specific aesthetic frameworks. For creative content, logical and mathematical checks do not apply, but the following mechanisms are available:
Music: Music theory provides a formal body of literature covering harmony, rhythm, counterpoint, voice leading, and genre conventions. A creative audio output can be checked against this literature — not as a correctness test but as a calibration signal for whether the work engages meaningfully with established structures. Platform engagement (Spotify, SoundCloud) provides the empirical check.
Visual art and photography: Aesthetic literature spanning thousands of years documents color science (complementary colors, perceptual color models), compositional frameworks (golden ratio, rule of thirds, visual balance), and cross-cultural aesthetic studies. These are data-grounded — extensive observation, cross-cultural replication, measurable perceptual response. Platform engagement (Behance, iStockPhoto purchase rates) provides empirical signal.
Cultural context: Aesthetic norms are not universal. A work conforming to Western conventions may violate Eastern ones. The field classifier identifies the intended cultural context, and aesthetic checks apply against the norms of that specific context — not a universal standard.
Overton window: The Arbiter assesses whether a creative work falls within the current Overton window for its field and cultural context — the range of expressions currently considered socially acceptable for public distribution. This is a social calibration signal, not a quality judgment. Content outside the window is not wrong, but its placement affects discoverability efficacy and platform viability.
What remains unresolved: The parser for extracting structured claims from non-text STEM media requires significant engineering. The assertions store schema for visual and audio content has no current design. The cultural context classifier is a hard classification problem with no clean training signal. The Overton window is dynamic and geographically variable — operationalizing it as a continuous check requires a regularly updated model of social acceptability per field per region.
3. Assertions store decay class assignment
The decay class system (Class A–D in §10.5) requires each assertion to be assigned a decay class at write time. The assignment logic — determining whether a given fact falls into "no decay" (mathematical proof) vs. "fast decay" (clinical guideline) — is itself a classification problem. Edge cases exist: is a well-replicated empirical finding in physics Class A or Class B? Is a long-standing medical consensus that has never been challenged Class B or Class C? The initial calibration is a heuristic; a systematic method for decay class assignment is needed.
The framework described here treats AI competence as a dynamic, measurable, self-improving property rather than a static artifact of training. By wrapping a frontier model with a utility layer grounded in contradiction detection, efficacy measurement, and field-specific societal standards — and connecting that utility layer to a three-tier continual learning architecture — we create an agent that knows what it knows, knows what it doesn't, actively corrects what it gets wrong, and does so between model releases rather than waiting for the next training cycle.
The key contribution is that the utility function is not a monitoring metric. It is the loss weighting mechanism for calibration, the trigger for behavioral correction, and the acceptance criterion for adapter deployment. It governs learning at every timescale.
The MVP simulation in code generation (Appendix A) validates this core claim: utility-weighted DPO calibration measurably reduces contradiction rate and improves efficacy across successive calibration cycles, with difficulty escalating as domain confidence rises and efficacy accumulating via EMA rather than resetting per interaction.
The game-theoretic treatment in §10.6 adds a formal incentive-structure foundation to the Arbiter Agent. The VCG mechanism does not change what the Arbiter does — it changes why the submodels can be trusted to report their utilities truthfully. Theorems S1–S3 prove that, under the VCG mechanism, dominant-strategy equilibrium coincides exactly with the social optimum, with no efficiency loss and no need for external calibration audits. This closes the gap between the engineering approximation currently deployed and the theoretical ideal toward which Phase 6 architecture converges.
This is a living document. Mathematical foundations for the utility function, confidence dynamics, and personality stability are formalised in Appendix B. Priorities 1, 3, and 5 from the mathematical theory roadmap — Price of Anarchy bounds, SPRT threshold optimality, and the 2/3 gap budget derivation — remain as future work.
