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.

flat-then-break
ThesisCM trades below composite fair value $138.90 with a risk-on tape and low-intensity but durable compounder narrative. Mild sentiment drag and stretched 6mo return of 25.6% cap near-term upside, but value gravity plus low beta pull the path toward the $130 baseline over 6 months.
Invalidated ifClose below $108 (attractive-value line) or regime flip to risk-off with break of 3m uptrend invalidates the drift-higher thesis.

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
$130.56
(+10.0%)
— both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it.
