"Not a dashboard of green rings. A room where the pattern you could never hold in your head is finally sitting still enough to read."
The Surface Waystone Does Not Have
Stream, Modules, and Medical are shared with the Waystone shape. Analysis is the surface Forge added, and it is where the engine earns its keep. It is not a fitness tracker's wall of rings; the target experience is a sentence like: "this flare pattern shows up in the week after heavy lower-body sessions — and here are the three times it did not. What was different?" That is the product. Not a score that goes up, but the correlation no one can carry in their head across months, surfaced and legible.
One Store, Four Views
Analysis is not a separate database; like the other three tabs, it is a projection of the same crumb store. Stream reads the crumbs as a diary, Medical reads the document ones as a shelf, and Analysis reads the interpreted layer as aggregates. Nothing in Analysis is a second copy of the truth — it is a lens onto the crumbs and their readings. That is why improving interpretation (Track 4) instantly sharpens Analysis: they are the same data, read at a different altitude.
Why It Is the Payoff Track
Every earlier discipline was setup for this room. Free prose gave honest raw material; the typed layer made it comparable; the no-terminal-state loop kept the whole timeline in view. Analysis is where those pay off as a readable pattern — and where the three rules of the next lessons keep the reading trustworthy. Build the reading room badly and the engine becomes a guessing machine with a medical vocabulary; build it under the rules, and it becomes the thing that walks beside Dad into the exam room.
