End-of-week model audit. G-Prophet signal review, unfiltered.
Strong: momentum continuation calls on mid-cap tech held up well Mon-Wed. Confidence intervals were tight, outcomes landed inside them.
Weak: Thursday volatility spike. Our vol-adjusted signals lagged by ~40 minutes. Not a bug, a structural gap in how we weight intraday regime shifts.

The more interesting finding: Friday close behavior.
We identified a consistent directional bias in our signals after 3:30pm ET.
