add-column-to-table

User initiates column creation via the table editor toolbar. The journey covers the column-name input surface (typed-name for Sara, literal-language for Nate), the advance-notice strip for destructive-adjacent DDL operations (Nate), and post-save feedback including KPI impact (Sara) and team context (Monica).

Three vehicles, three routes

Connector · Battleship

Monica

sea route

“Bring the team into the workflow.”

cognitive justification

HSP flood + Connector → activity context softens schema change anxiety. The collab rail surfaces who else is viewing this table; the save-ack transfers cognitive load to social precedent (GABA −22 sensory gating).

cognitive justification

ASD prediction-error (κ + 26) + ADHD DA-seeking → the advance-notice strip's 3s countdown buffers schema-change surprise. Literal column-type labels prevent GLUT-drain from phonological processing; zero motion respects HSP flood.

cognitive justification

CORT +19 (anxiety) + Analyst (A 0.000) → typed-name confirmation enforces deliberation. KpiBand + SaveLedger provide immediate numeric feedback on row impact, satisfying DA-seeking with precise, actionable data (motion 120ms).
