How the Validation Engine Operates

Wobbly Blocks processes your course tape through a deterministic rule engine that measures every stretcher, header, closer, and bat against the geometric laws of eighteen authentic brick bonds. The interactive Lay Bench renders units on a gauge grid at true brick proportions, tracking lap fraction, perpend offset, and running-joint count in real-time as you place each unit.

When you seat the course, the engine evaluates it immediately: Sound passes without reservation, Marginal stands but invites scrutiny, Unsound fails validation outright. Seven fault classes ranging from running joints to out-of-plumb bulges are identified by type, graded by severity, and explained in plain masonry terminology that apprentices and journeymen actually use on the bench.

The validation logic is repeatable and transparent. The same course tape run through the same strictness level produces identical results every single time, eliminating guesswork and reinforcing pattern recognition through consistent feedback loops reinforced by haptic confirmation for clean courses and warning pulses before errors solidify.

Core Masonry Features

Interactive Lay Bench

True-proportion gauge grid displays stretchers, headers, closers, and bats in real spatial relationships. Live rule tracking updates lap fraction and perpend alignment with every unit placement before the course is seated.

Eighteen Bond Atlas

Comprehensive reference covering Stretcher, English, Flemish, Garden-Wall, Monk, Quetta, Herringbone, and eleven additional patterns. Each entry documents historical era, regional usage, required lap measurements, and quoin-setter protocols.

Camera Wall Dossier

Point your device at existing brickwork to transcribe courses automatically. The engine identifies the bond pattern with confidence percentages, reads the four-course gauge rod, and generates a complete fault report for field analysis.

Haptic Validation Feedback

Receive tactile confirmation when laying sound courses through subtle haptic ticks. Warning buzzes alert you to marginal or unsound placements before mortar application, reinforcing muscle memory through sensory channels.

Statistics Dashboard

Track your soundness score progression across sessions. Visualize fault distributions by class type, map which bonds you practice by day, and monitor improvement curves from apprentice tolerance through master-level precision.

Twelve Structured Drills

Progressive training sequences from Half Lap basics through advanced Pockets and Bars in reinforced Quetta bond at difficulty level five. Each drill isolates specific techniques with incrementally tighter tolerances as your skills develop.

Validation Mechanics & Fault Classification

Rule Engine Logic

Deterministic validation produces identical results for repeated course tapes under constant strictness settings
Lap fraction calculated to quarter-brick precision for all eighteen bond patterns simultaneously
Perpend offset tracking identifies vertical joint misalignment before running-joint faults develop
Running-joint counters accumulate across courses to flag broken bond conditions early
Quoin closer requirements enforced at wall ends based on specific bond type constraints
Snap-header misuse detected when half-bats appear in header positions contrary to bond rules

Graded Fault Classes

Running joint severity graded by vertical stack height accumulation across successive courses
Broken bond evaluated against lap requirements specific to the eighteen supported patterns
Wrong lap faults reported with actual measurement versus required lap for the identified bond
Missing quoin closer detected at wall terminations where closer placement is geometrically mandatory
Weeping perpend warnings issued when joint widths exceed acceptable masonry tolerances
Out-of-plumb bulge analysis flags lateral displacement beyond the selected strictness threshold

Educational Methodology

Wobbly Blocks translates centuries of bricklaying craft knowledge into interactive validation rules that apprentices can test repeatedly without wasting materials. The three strictness levels mirror real trade progression: Apprentice mode allows exploration with forgiving tolerances, Journeyman enforces professional standards, and Master demands precision that meets historic guild requirements.
