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.

ThesisCB is a high-quality compounder trading modestly above fair value in a risk-on tape with negative beta, so near-term drift is mildly positive on momentum and quality bid, but value gravity toward the low-$300s reasserts over the medium term as the priced-for-perfection overhang caps upside.
Invalidated ifA break above $370 on sustained volume or below $325 would invalidate the mean-reverting drift 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
$347.16
(-1.5%)
— both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it.
