Spread Windows: The Public Log

Windows we detected, published after close. When our nightly detection finds a spread that shouldn't exist — vendor bids above retail asks after all real costs — it logs the window and the full math. Entries appear here only once the window has closed, as a verifiable record of what the detection caught and how long it lasted. Not tips; by the time you read this, it's over.
