The Rubric Bank — with all five levels

Managing breathing to support vocal performance without unintended interruption

Producing letters from their correct points of articulation, especially the similar ones

Building a gradient of vocal energy that leads the listener toward the climax

Using intentional silence (the pause) to build tension and meaning, not just to breathe.

Your writing line's deviation from true horizontal, in degrees, computed by a real geometric Hough transform on your own photo's pixels — never a visual estimate

How consistently your pen's stroke direction holds across several points in your panel, measured from the local ink orientation around each point you mark (a platform-declared measurement standard, not a historical figure) — an unstable pen angle signals inconsistent pen-grip control, not a letter-shape flaw

How steady the pen's stroke thickness stays along one letter you mark (measured by the coefficient of variation of several cross-section widths along that same stroke) — thickness varying WITHIN one stroke signals uncontrolled pen pressure, unlike the intentional thick/thin contrast between different strokes in the script itself

The balance of how letters and words are distributed across the whole panel's space, and how the larger gaps (between words and lines) relate proportionally to the smaller ones (between letters)

Choosing materials appropriate to product and ensuring their quality

Executing product with precision and attention to detail

Quality of product's final appearance and concealing manufacturing flaws

Adhering to planned dimensions and measurements

The product performing its intended function efficiently and comfortably

The product's ability to withstand use and time without damage

Quality of joining the product's parts and concealing or intentionally revealing joints

Tight joints and a piece that holds functionally: the joint bears load, the vessel doesn't leak, the structure doesn't loosen.

Discipline of axes, measurements, and repetition; intended symmetry or its intended breaking.

Centring the clay mass steadily on the axis before forming — the base of every balanced ceramic piece.

Even wall thickness from base to rim, a sign of control and material efficiency.

Tuning thread tension so it neither puckers the fabric nor leaves the stitch loose.

Tight wood joints (mortise-tenon, dovetail) without gaps, holding without relying on glue.

Clean, tight solder joints without gaps, excess, or burns.

Symmetry of the metal piece's axes and precision of its repeated measurements.

Precision of the Islamic ornament grid and the symmetry and closure of its repeat.
