Plate VI — Precision

Structural intent

Show exactness through joinery, fit, alignment, and measured construction. Precision is evidenced by tight tolerances and repeatable geometry.

What must be observable

• Tight joints (stone blocks, tiles, metal seams) with minimal gaps.
• Straight edges and consistent angles.
• Evidence of measurement: uniform spacing, consistent module sizes.
• Clean intersections (corners, joints) that demonstrate controlled assembly.

Common failure modes

• “Clean-looking” surfaces without observable joints or alignment evidence.
• Decorative detail mistaken for precision (ornament ≠ tolerance).
• Lighting hides edges, making fit unverifiable.
• Perspective distortion that makes lines appear misaligned.

UI / system translation (non-symbolic)

• Use for settings, calibration, and verification screens.
• In UI: pixel-perfect alignment, baseline grids, consistent spacing scale.
• In system terms: validations, constraints, and schema-level enforcement.
• QA: require visible edges/joints; reject blurred/hidden tolerance cues.
