  • The lack of a controlled vocabulary for first-derivative behavior and second-derivative behavior. The need for a derivative and trajectory layer in the Accessibility Geometry framework.

    Accessibility Geometry Reference Stack: Reference B - Accessibility Derivative Register · 2026 · DOI

  • Reference B establishes a derivative vocabulary for Accessibility Geometry, but substantial work remains. Future work should proceed along six tracks. 14.1 Domain-Specific Proxy Development Each substrate requires its own proxy variables. For human observers, candidate proxies may include planning horizon, stress load, self-report, behavioral flexibility, memory reconstruction, and support availability. For organizations, candidate proxies may include reporting latency, decision-loop speed, corrective-action closure, role clarity, staff turnover, audit responsiveness, and procedural adaptability. For institutions, candidate proxies may include precedent integration, transparency, appeal pathways, record integrity, legitimacy signals, and correction capacity. For synthetic systems, candidate proxies may include context retention, memory utilization, tool- use stability, self-correction rate, hallucination persistence, recursive loop detection, and task- continuity integrity. 14.2 Derivative Threshold Calibration Reference B does not define universal thresholds. Future work should calibrate: A_crit RM_crit T_h_crit B_a_crit and related warning thresholds by substrate and context. Thresholds should not be imported across domains without justification. 14.3 Toybox Simulation Future Accessibility Geometry toybox investigations should simulate: • gradual accessibility contraction; rapid projection-horizon collapse; • false coherence; • recursive closure acceleration; • recovery reindexing; • • unbounded expansion; scalar fragmentation; • impedance spiral; • constraint collapse; • emergency descent. • These simulations should distinguish recoverable drift from collapse trajectory. 14.4 Genesis ODE Integration Future Genesis work may incorporate Accessibility Dynamics as a companion layer. This should be done without collapsing accessibility into coherence. Candidate integration pathways include: treating A(t) as a navigation variable coupled to but distinct from C_X(t); • • using Phi(t) as a loop-density warning variable; • using RM(t) as a maneuvering-space variable; • using T_h(t) and B_a(t) as self-governance capacity variables; • modeling stress as a driver of projection-horizon contraction; • modeling reorganization capacity as a recovery gate. The guiding rule should remain: Coherence is not accessibility. 14.5 Human TAWS Prototype A future Human TAWS prototype should define: 1. monitored variables; 2. observation windows; 3. derivative thresholds; 4. warning-level transitions; 5. substrate-specific response guidance; 6. false-positive handling; 7. false-negative review; 8. recovery-state detection; 9. hard-halt candidate logic; 10. limits of authority. The prototype should begin as a decision-support model, not as an automated command system. 14.6 Reference C and Relational Variables Reference C should address relational and coupling variables not fully developed in Reference A or Reference B. Candidate Reference C topics include: • Shared Geometry; • Trust; • Perceived Observer Value; • Geometric Cohesion; Information Acquisition Cost; • • observer-to-observer coupling; • multi-scale synchronization; • • • relational impedance; stewardship responsibility; cross-scale governance. Reference B should therefore be understood as the derivative layer, not the final relational layer.
