Knowledge Proficiency

A reified, leveled depth-of-knowledge of an agent toward a subject — the gufo:Relator binding {agent} × {subject} × {level on a scale} × {interval}, mirroring expertise's gmeow:SkillProficiency. Founded on the gmeow:CognitiveState mode (documentation, not an axiom — Principle 12); the mode and this relator are DIFFERENT individuals, never double-typed. Flat-first: the four-level knowledge spectrum (gmeow:isAwareOf … gmeow:hasMastered) is the cheap surface; promote to a KnowledgeProficiency when level, scale, temporal scope, or standpoint matters. Suppression not deletion (Principle 10): lapsed knowledge is recorded as a closed interval / gmeow:displayable false, never deleted. Boundaries, documented WITHOUT axiom bridges (Principle 9): cognition (knowing, objectual) ⊥ epistemics (believing, propositional); cognition ⊥ expertise (knowing ⊥ can-do — gmeow:hasSkill ⊑ gmeow:knowsAbout touches the axes at one rung only).

Structure

Subclass of: gufo:Relator

Practical Pattern

Use gmeow:KnowledgeProficiency as a specialized kind of gufo:Relator. Add statement metadata or a standpoint when the assertion needs provenance, confidence, or vantage.

# Worked example: the Dunning–Kruger case, modelled as COEXISTING standpoint-indexed
# claims (Principle 9), never a global verdict. Sam self-assesses MASTERY of
# quantum computing; an external assessor rates the same knowledge merely as KNOWS-ABOUT.
# Two gmeow:KnowledgeProficiency relators over the same (agent, subject), at
# divergent gmeow:KnowledgeLevel values, each indexed by gmeow:accordingTo to a
# different vantage. GMEOW records the disagreement; it does not adjudicate it.

# Worked example: the reified knowledge tier. The flat spectrum (gmeow:hasMastered
# &c.) says HOW DEEP; the reified gmeow:KnowledgeProficiency adds the SCALE it is
# read against, a temporal interval, and a standpoint — the promotion path when
# level, scale, time, or vantage matters (Principle 4). Suppression, not deletion:
# lapsed knowledge is a CLOSED interval with gmeow:displayable false, never removed
# (Principle 10). The mode (gmeow:CognitiveState) and the relator
# (gmeow:KnowledgeProficiency) are DIFFERENT individuals — never double-typed.

# --- Promote to a reified proficiency: depth read on an explicit named SCALE,
#     over a temporal interval. The flat hasMastered above and this relator
#     coexist; gmeow:pairsWith links the two forms.
