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
ThesisWDC is extended far above any reasonable fair value with a cracking AI-storage narrative, high beta, and risk-off sentiment; near-term momentum keeps it elevated but value gravity and sentiment drag pull it materially lower over the six-month window, though nowhere near the $52 deterministic anchor.
Invalidated ifA break and hold above $480 on renewed AI-storage upgrades, or regime flipping decisively risk-on, would invalidate the fade 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
$287.40
(-34.9%)
— both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it.
