Chronostrand: Four Ages of the Cavern Playable Age Braid Foundation Sprint 01

Chronostrand: Four Ages of the Cavern completed its first playable Age Braid sprint with traceable Sinklight records, structured content, and deterministic Unity runtime code.

Chronostrand: Four Ages of the Cavern completed its first playable Age Braid foundation sprint.

The sprint turned the opening Sinklight Threshold slice into traceable production material: Rain Mouth, Blue Drip Shelf, Survey Camp One, First Anchor, Map Lantern, Nox Resonance, anchor-only age switching, safe invalid-switch denial, Survey Beacon recovery, Nox Charges, deterministic starter rewards, and no gameplay/failure/save ad pressure.

The VeritySpec records now cover Nox Resonance scanning, anchor-only age switching, safe switch denial feedback, Survey Beacon recovery, Sinklight foundation rewards, invalid switches that never damage the player, pre-scan suspicion requirements, non-color-only age cues, and commercial guardrails around traversal, failure, and saving.

Structured content now has stable IDs, localization keys, source references, unlock paths, economy posture, and QA expectations for the starter rooms, age states, Nox Charges, Survey Beacon, rewards, invalid-switch feedback, and slow age selector assist.

On the Unity side, the deterministic runtime model represents room age availability, scan targets, switch validation, denial reasons, Nox Charge damage and recovery, reward claiming, campaign-valid age selector modes, forced-ad suppression, and rewarded-ad offer gates.

This is still before scene implementation. The next Chronostrand step is to configure Unity EditMode coverage, build the first greybox Sinklight prototype scene, expand the starter route with authored safe overlaps and map review, then use headless Unity plus available Android device validation when the prototype has something meaningful to run.
