ThesisBLDR trades well below composite fair value but sentiment is decisively negative amid a rolling-over housing narrative and high beta. Expect near-term drift lower or sideways as tape pressure dominates, then a partial mean-reversion toward the low-80s as value gravity reasserts over months, though not a full close of the gap.
Invalidated ifA break below $60 on housing-data deterioration, or conversely a decisive move above $88 negating the bearish sentiment overhang, invalidates this path.

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 $80.35 (+10.9%) — both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it. Brain: claude-opus-4-7.
