Lab — UI glossary

When the docs mention "the inspector" or "the playhead," this page is the canonical definition.

Studio surfaces

Studio — the main app screen
Timeline — the bottom strip showing the day
Signal chart — the center time-series view
Right drawer — the right-side panel; tabbed between Inspector and Sim, collapsible
Inspector tab — the editing surface inside the right drawer; carries a count badge when interactions are firing on the selected item
Sim tab — the AI assistant chat surface inside the right drawer
Inspector panel / inspector — the body inside the Inspector tab when an item or signal is selected
Signal inspector — the inspector body shown when a chart signal is the selection target (rather than a timeline item)
Enzyme detail panel — replaces the inspector view when an enzyme chip is clicked; shows live activity, sparkline, composition, and active modulators
Scenario selector — the top-bar scenario picker

Playhead — the vertical time cursor on the chart
Signal toggle menu — the dropdown for picking which signals to chart
Meters strip / Meters panel — the half-circle gauge readouts for subjective states (Energy, Focus, Calm, Mood, Social, Overwhelm, Sleep Pressure); engine-computed, not raw weighted sums
Heatmap — the body-system color view
Arousal band — the sympathetic / parasympathetic strip
Group toggle — switch the chart grouping between Biological System, Goal, Kind, and None

Type — biological family of a signal (hormone, neurotransmitter, metabolic, etc.)
Kind — representation paradigm of a signal (analyte, drug-concentration, vital-sign, body-composition, flux, activity, pool, index, pro) — drives how it's rendered and grouped
Measurability — how a user can obtain a value (lab / CGM / wearable / self-report / anthropometric / modeled-only)
Timescale — dominant change rate of a signal (seconds, minutes, hours, days, weeks, months) — drives the default chart zoom
Subjective state / PRO — patient-reported felt experience; the seven meter dials are the engine-computed PRO outputs

Citation pill — small colored pill on every cited row in the inspector (green = literature, blue = calibration, red ⚠ = uncited). See Citation pills.
References section — the numbered source list at the bottom of every inspector view; collapsed by default, auto-expands when you click a pill.
Interactions section — the inspector section listing every interaction rule firing on the selected item, sorted by severity.
Interaction detail view — replaces the inspector when you click an interaction row; shows mechanism, remediation, items involved, affected signals, citations, derivation.
Severity — one of critical (red), warning (amber), benefit (green), or info (blue). Same color appears on the timeline item border, the inspector chip, the tab badge, and the chart pill.
Derivation chip — labels how an interaction rule was generated: Clinical look-up, Model-emergent, or Mechanistic inference.
PharmD review pending chip — surfaces on rules that haven't been reviewed by a contracted pharmacist yet.
