15. Second-Order Dialect Evolution

15.1 Empirical Dialect Improvement

A dialect is not a fixed standard. It is a living observation apparatus that evolves from its own empirical results. RFC-035 §2.2 establishes second-order criterion evolution — the system generates new observation criteria from its own empirical history.

At the dialect level, this manifests as:

Signal Dialect Evolution Response
A variable produces no gaps across N evaluations The variable may not capture the construct it claims to. Investigate or remove (MAJOR).
A variable always produces gaps (100% MISMATCH) The threshold may be miscalibrated, or the variable measures something every system fails. Recalibrate (MINOR) or redefine (MAJOR).
A new concern pattern emerges not captured by existing variables A new variable is needed. Add (MINOR).
Observer disagreement is high on a specific variable The extraction method may be ambiguous. Refine (PATCH) or restructure (MINOR).
Cross-organizational comparison reveals systematic divergence The dialect may have insufficient specificity. Consider derived dialects for sub-populations.

15.2 Evolution Governance

Dialect evolution is not automatic. It is governed:

  1. Longitudinal verdict data is accumulated (RFC-032 behavioral baselines)
  2. Statistical signals are detected (variable-level gap distributions)
  3. Evolution proposals are submitted (structured change requests to the registry)
  4. Peer review evaluates the proposal against construct validity
  5. New version is published if review passes
  6. Subscribers are notified; migration path is documented

This mirrors the scientific cycle: accumulate evidence → propose theory revision → peer review → publish → community adoption.
