Forecast
The masterbrain trajectory — 7 dated checkpoints. Short rungs (2w, 1m) show the typical range as the primary claim; point calls run from 2 months out. Every claim still gets graded.

ride-then-fade
ThesisROST trades well above every fair-value anchor but quality is pristine and momentum plus off-price narrative keep near-term downside gentle; over six months value gravity and a rich-multiple whisper pull the price modestly lower toward the deterministic baseline, with an earnings print in the window as the main bend.
Invalidated ifA decisive break above $250 on strong Q3 comps, or conversely a break below $205 on a guide-down, would falsify this gently declining path.

Convergence toward baseline as premium slowly bleeds
Why ranges on the short rungs?
A 102-prediction trial (2026-07-21) showed 2-week point calls carry no information here —
three prompt formulations all lost to simply predicting zero — while the stock's own
volatility scale (σ×√t) described those windows well. So the short rungs claim what's
actually knowable: the typical travel, with earnings timing flagged where the variance
will come from. The internal point calls keep being generated and graded to map where
real skill begins. Full evidence: stocks/predictions/V0.5-DESIGN.md §8.
Deterministic control (v0.3 value line) targets
$214.11
(-9.2%)
— both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it.
