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.

decay
ThesisPRU trades well above every fair-value anchor with negative value and sentiment scores, but low beta (0.24) and defensive character mean mean-reversion will be gradual rather than violent. Expect a slow drift lower toward the deterministic baseline as the fallen-angel narrative persists absent an earnings catalyst.
Invalidated ifA close above $128 on positive guidance revision, or below $108 on credit/spread shock, would falsify this measured drift.

Gradual reversion begins as overvaluation reasserts
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
$112.38
(-6.3%)
— both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it.
