From the alpha workflow.
State variables, sampling decisions, memory features, and what the evidence is showing. Each note names the sample, names the label, and reports the result — pass or fail.

01Locking the first three raw atoms
A 1,000,000-event evidence pass on four candidate raw microstructure atoms — what locked, what got dropped, and what survives into Stage 2.

02Four trade-aggression atoms — and three of them collapsed
A 1,000,000-event evidence pass on four new trade-aggression atoms. Three of them turned out to be the same axis as raw_trade_ofi. One survived as a WATCH.

04Why your backtest lies to you (and how to make it stop)

05Market microstructure, explained like you'll build something with it
A first-principles tour of order books, queues, price formation, and the execution reality hiding underneath every candlestick.
Every note names the sample, names the label, and reports the result. Pass or fail. The lab’s harness, study code, and diagnostics live on GitHub.
