Iteration 29 — Implemented-first works 3/3 CLEAN · 103 TOTAL STRATEGY VALIDATED IN ONE FIRING

In plain words: yesterday's finding became today's method, and the method worked on the first try. After the code-gap discovery (three of five paper-first entries had no implementations), this firing inverted the search: find the maintained library first, then verify its paper backward. Three entries, three clean catalogs, zero casualties. The haul: the refutation battery from the causal-inference ecosystem's flagship library (updated literally yesterday, 8,200 stars) — a structured suite of "try to break your own claim" probes including the one no gate in the lab's stack covers, sensitivity to unmeasured confounding; the E-value — a closed-form answer to "how strong would hidden confounding have to be to explain this away?" (with a note disambiguating it from the betting e-values elsewhere in the catalog — same name, entirely different object); and J-PCMCI+, which completes the catalog's causal-discovery quartet: one engine each for plain autocorrelated series, hidden confounders, named regimes, and pooled multi-regime datasets. The STABLE boundary is at 41 of 100 — the long pole is shortening.

 D1-01 (iter 28, paper-first):        5 harvested → 3 NO-IMPL casualties
 D2-01 (iter 29, implemented-first):  3 harvested → 0 casualties
 The code-gap finding paid for itself in one firing.
 PCMCI quartet now complete: PCMCI+ (base) · LPCMCI (latent) ·
 regime-MCI (named regimes) · J-PCMCI+ (pooled contexts)
