Dot Whorl: Number Trails Playable Trail Check Foundation Sprint 01

Dot Whorl: Number Trails completed its first playable trail-check foundation sprint with traceable Journey records, structured starter content, and deterministic Unity runtime code.

Dot Whorl: Number Trails completed its first playable trail-check foundation sprint.

The sprint turned the redesign package into traceable production material: Journey Chapter 1 starter puzzles, start-at-1 trail arming, orthogonal trail extension, ordered numbered dots, exact board coverage, rewind, Undo, Restart confirmation, free Check Path, neutral error feedback, tap-to-move, High Contrast, Reduced Motion, and no active-solving commercial interruption.

The VeritySpec records now cover trail arming, legal orthogonal moves, checkpoint order validation, free recovery, Check Path, exact-coverage completion, board readability, campaign-valid accessibility settings, and the rule that Dot Whorl helps reasoning without monetizing confusion.

Structured content now has stable IDs, localization keys, source references, unlock paths, economy posture, and QA expectations for Journey Chapter 1, five starter puzzles, drag-to-draw, tap-to-move, Check Path, Undo/Restart, Nudge, endpoint and error states, High Contrast, and Reduced Motion.

On the Unity side, the deterministic runtime model represents puzzle definitions, playable cells, checkpoints, trail state, start validation, legal move validation, rewind, Undo, Restart, Check Path results, completion validation, commercial-surface gating, accessibility mode validity, and competitive validity around paid assist.

This is still before full scene implementation. The next Dot Whorl step is to build the first portrait Unity greybox scene for Journey Puzzle 1, add EditMode coverage around the runtime model, and use headless Unity plus the available Android device path once the live trail interaction has meaningful board input and feedback.
