Triad Derivations — Computed Outputs from the Triangle

The Triad (VISION.md, SPEC.md, BUILDING.md) is a normalized data store. These commands are views — computed fresh from the three source documents every time. Nothing is cached. Nothing goes stale.

Core Principle

Every derived output is a function of deltas between the three documents:

VISION - SPEC           = gap (what doesn't exist yet)
SPEC - BUILDING         = undocumented work (exists but not journaled)
BUILDING -> VISION      = trajectory (converging or drifting?)
BUILDING velocity       = momentum (what ships fast vs. slow)

The three documents dictate priority, order, and urgency. No human maintains a separate roadmap or status page. The triangle produces them.
