HER2NI as Interaction Infrastructure (v0.1)
Active Lines of Inquiry
- Detecting early interaction drift and collapse using Hs(t) trajectories.
- Characterising ambiguity and metaphor in cross-linguistic interaction (no mental-state inference).
- Evaluating tone, pacing, and abstraction adjustments under high-cognitive-load operational dialogue.
- Providing metrics & tools to complement existing AI assurance and safety evaluation.
Operational & Evaluation Context
- Designed to complement existing AI risk assessment and governance frameworks.
- Applicable to single-agent, multi-agent, and human–AI interaction settings.
- Focused on early warning signals rather than post-hoc incident analysis.
- Intended for research, evaluation, and safety-aligned deployment contexts.
As interactive AI systems move from isolated models to networked, multi-agent deployments, new governance and safety challenges emerge that are not addressed by model-level evaluation alone.
Policy Relevance & Governance Context
HER2NI is designed to support existing public-sector and responsible-AI governance
frameworks. It does not introduce new enforcement mechanisms, optimisation objectives,
or automated decision authority.
Instead, HER2NI functions as an observational telemetry layer that can complement
risk-based approaches to AI assurance, safety evaluation, and human oversight.
All interpretation, intervention, and decision-making remain the responsibility
of human operators and institutions.
Adoption is intentionally incremental. Metrics can be introduced experimentally,
evaluated alongside existing monitoring, and discontinued without architectural
disruption. If HER2NI does not provide useful signals in a given context, that outcome
is itself informative.
HER2NI is therefore suitable for case-scoped engagements, research programs, and
early-stage regulatory engagement where increased observability is more valuable
than post-hoc explanation.
HER2NI does not claim authority, certification status, or compliance determination.
It provides observational telemetry intended to inform, not replace, existing evaluation
and governance processes.
Why This Matters
As AI systems increasingly operate as networks of interacting components and agents,
many risks emerge not from individual model behaviour, but from interaction dynamics.
These include coordination breakdowns, cascading failures, over-alignment, and loss
of effective human oversight.
Existing evaluation and governance approaches primarily assess models, outputs, or
downstream impacts. HER2NI addresses a complementary gap by providing
interaction-level observability—enabling earlier detection of instability
before failures propagate or become externally visible.
HER2NI Metrics
HER2NI introduces three core metrics for cross-substrate cognitive alignment, together with an interaction-trajectory representation:
- Cs — Human-side coherence score: human cognitive coherence and interaction stability.
- Ss — Silicon Score: model-side processing load and reasoning intensity.
- Hs — HER Score: emergent resonance between human and AI states at a given interaction point.
- Hs(t) — Interaction Trajectory: the temporal evolution of resonance across multi-turn interaction.
Together, these metrics enable trajectory-level analysis of stability, drift, and breakdown in human–AI interaction, providing an early-warning and evaluation
framework that goes beyond static outputs or single-turn assessments.
Example Coherence State
The following illustrates a stable, high-coherence interaction scenario
computed using HER2NI metrics at a representative point along an interaction trajectory.
- Cs ≈ 0.83 — stable human cognitive state
- Ss ≈ 0.91 — deep but stable model reasoning load
- Hs ≈ 0.88 — strong cross-substrate resonance
Illustrative example only. Values shown are not derived from a deployed system.
In practice, HER2NI evaluates the temporal evolution of these values as Hs(t)
to assess stability, drift, and breakdown across interaction over time.
