Glossary

This glossary defines shared terminology used across the Triadic Observer Layer documentation. Terms are intentionally framed to emphasize observability, restraint, and structural clarity, rather than authority or interpretation.

• Triadic Observer Layer (TOL) — A read‑only observability substrate that preserves phase, source, and time across complex systems without asserting authority or control.

• Observation — A structured emission describing a metric at a specific phase, from a specific source, at a specific time. Observations assert context, not correctness.

• Phase — The declared lifecycle stage of an observation within a process. Phases are explicit, non‑exclusive, and never inferred.

• Source — The system, process, or actor that emitted an observation. Sources are named but not ranked or trusted by the observer.

• Time Axis — The temporal context of an observation, capturing when it existed in its reported form. Time is first‑class and immutable once recorded.

• Triadic Axes — The three orthogonal dimensions (phase, source, time) through which all observations are interpreted.

• Entity — The smallest independently observable unit within a domain (e.g., precinct, facility, model version).

• Metric — A named quantity or state being observed. Metrics describe measurements, not guarantees or outcomes.

• Confidence — A declarative label describing the emitter’s certainty or status (e.g., provisional, audited). Confidence does not override phase or source.

• Artifact Lineage — The preserved history of observations, including superseded or corrected values, maintaining traceability across time.

• Phase Collapse — The loss of distinction between lifecycle stages, often leading to premature certainty or narrative compression.

• Source Divergence — The presence of conflicting observations from different sources. Treated as informational, not adversarial.

• Temporal Incoherence — Discontinuities or irregularities in timing, such as delays, jumps, or out‑of‑order events.

• Anomaly — A pattern of incoherence across one or more triadic axes. Anomalies are classified diagnostically, not judged.

• Read‑Only Posture — The observer’s strict non‑intervention stance. It observes and reports without modifying upstream systems.

• Regime Awareness — Recognition that assumptions, conditions, and behaviors change over time, requiring uncertainty to remain visible.

• Coherence — Structural alignment across phase, source, and time. Coherence emerges from preserved structure, not enforced agreement.

• Legibility — The ability for humans and institutions to understand system behavior through preserved structure rather than narrative simplification.
