Writing
The record.
Every piece ships with its receipts: fingerprinted, and linked to the ledger it came from. Nothing here asks to be taken on faith.
The Number Moved, the Model Didn't
A sleep-stage classifier, and six methodological decisions that each move the headline number while only one of them moves the model. Eleven points of accuracy from a single preprocessing flag, and none of it dishonest.
Fail-Closed by Construction
An operational record of a policy-constrained, provenance-first LLM agent runtime over 230 passes: an 82.8% pass success rate with a 25-group failure taxonomy, a strict evidence-admission funnel, one auditable epoch transition at the context ceiling, and an authority boundary that held for the entire run.
Six Ways an Eval Lies
Six structural defects that shipped past a preregistered evaluation process, and the domain-blind checks that catch them before a run is burned. The tests were correct at every line and still couldn't measure what they claimed.
