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 sits below composite fair value ($136) with a neutral regime and no near-term catalysts; low beta and mild negative sentiment cap upside early, but value gravity pulls the stock toward the high $120s to low $130s over six months.
Invalidated ifA break below $105 on rising volume or a Canadian bank credit-quality shock would falsify the upward drift.

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
$128.30
(+9.0%)
— both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it.
