#16. Lab Note: We Built a Cycle Map for the S&P 500
Been quietly building a proprietary time-cycle framework, backtested against 25+ years of SPX data.
But two things just lined up: a sharp breadth breakdown, and our framework flagging a transition.

#15. Lab Note: Six Weeks In
Six weeks, fourteen posts in — time to take stock.
No dramatic new finding. Just enough on the table now to show how it fits together, and be honest about what's still missing.

#10. Framework III: The Center Post Low
Every T has a hinge point. Get it right, and the time symmetry that follows is remarkably accurate.
Get it wrong, and the error propagates twice.

#9. Framework II: The Cash Build Up
Everyone who finds T-Theory fixates on the projection — the target date, the symmetry.
But the projection only exists because of something that happens first, and it gets ignored: the Cash Build Up.

#8. Framework I: What is T-Theory
Markets spend roughly half their time going up, half going down — but compound higher over any long stretch.
Most call that noise. Terry Laundry spent 40 years treating it as a clue.
