HRIS concept / TFS
Core vocabulary
Trajectory Fitness Score
TFS
Regime quality should be measured by fidelity under change, not by stylistic resemblance.
What it means
TFS is a proposed evaluation framework for scoring how faithfully an interactional trajectory persists across tasks, contexts, perturbations, and model changes. It separates superficial voice matching from deeper continuity in reasoning and correction.
What it does
TFS converts the qualitative claim of regime persistence into a testable measurement program. Candidate dimensions include constraint fidelity, epistemic discipline, transfer, recoverability, and resistance to false cues.
What would test it
Which observable dimensions best distinguish genuine regime recovery from generic instruction following or human projection?
