Governing question / How does information remain connected to the call it changes?

Decision grammar

Spatial contract

Concept	Role	Expression
Governing decision	Fixed datum	Largest open square; every branch can be traced back to it.
Objective	North constraint	Single line above the datum; never competes with the question.
Context	Field edge	Cropped annotation at the perimeter; available without entering the core.
Hypothesis	Branch	An angled claim line leaving the decision; weight reflects current support.
Option	Parallel path	Comparable paths share a baseline but may diverge in length and pressure.
Criterion	Measure cut	A short perpendicular mark crossing every option it evaluates.
Evidence	Attachment	A solid pin joins a source to one precise claim.
Assumption	Interrupted join	A visible gap weakens the connection it qualifies.
Unknown	Open end	A branch stops before resolution and carries a due point when owned.
Trade-off	Opposing pressure	Two inward cuts show the tension accepted between criteria.
Recommendation	Convergence	Supported paths narrow into a solid terminal block.
Risk	Cross-pressure	A diagonal cut challenges the path without replacing it.
Test	Return loop	A line returns from the recommendation to the claim being tested.
Next action	Exit vector	An owned line leaves the field with a verb and date.

Cobalt sharpens the current question; position and weight carry the same meaning in greyscale.

Teal uses a solid attachment. Assumptions use ochre and a broken join. Risk uses red and a crossing cut.

Ink, convergence and a filled terminal block. No accent colour is required.
