ThesisMPLX trades at a meaningful discount to composite fair value ($83) with attractive yield support, but negative sentiment and MLP stigma cap near-term upside. Expect gradual mean-reversion toward the low-$60s over six months, with the deterministic $69 endpoint likely too aggressive given sentiment drag.
Invalidated ifA break below $54 on distribution concerns or midstream sector selloff, or a surge above $65 on M&A/simplification news

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 $69.46 (+20.2%) — both lines get graded at every checkpoint, so the brain has to beat the formula, not just replace it. Brain: claude-opus-4-7.

Not Yet Modeled
What this v0.6.0 forecast deliberately ignores — the work ahead, in plain sight.- Scenario probabilities — one path, no bull/bear split (base_prob = 1.0).
- Intraday / sub-2-week behaviour — the first claim is at 14 days by design (EOD product).
- Position sizing / portfolio context — the path is a price claim only.
