Iteration 20 — EXPIRY refill, native-guarantee bar 5 HARVESTED · 84 TOTAL S-07 → B-05 NEXT

In plain words: yesterday's massacre wrote the shopping list. After three stack-adjacent detectors died at the gate, this refill admitted only mechanisms that carry their own printed guarantees or work in ways nothing in the lab's stack does. Five entered: the adaptive-windowing detector whose false-alarm bounds are theorems in its 2007 paper (exactly the trust-anchor currency the gates demand — in a very active library, updated four days ago); the 1954 inspection-scheme classic that fathered the whole field, entering explicitly as the calibration baseline; a density-ratio detector that sidesteps density estimation and bounds its objective under fat tails by construction; a spectral-subspace method on trajectory matrices (carefully distinguished from the boneyarded eigenvalue thresholding); and the matrix-profile segmenter, domain-agnostic by design. One refusal on the record: the always-valid p-value line was NOT catalogued — it's the ancestor of the e-value machinery already in the catalog, and an ancestor row would be a duplicate wearing a older name. If four of the five pass next firing's screen, the EXPIRY boundary finally reaches its handoff batch.
