Feature: ramsey_rothman_bicovariance_gamma21_lag1_midlogret
Stage: commit โ€” One atomic commit on the batch branch (no AI attribution; PITSLARP one-liner).
What happened this firing
Feature 3/8 (bar_ramsey_rothman_bicov_lag1 โ€” time-irreversibility: whether recent returns look different played backwards) COMPLETE โ€” all 16 stages in a single fire. This is the FIRST continuous (non-bit-exact) feature: gamma_{2,1}/sigma^3 uses ln + std + cubing, so it matches the numpy oracle to <=1e-9 rather than bit-for-bit โ€” measured residual 9.5e-14 (BTC) / 1.1e-13 (ETH), ~4 orders under the gate. Built+committed: oracle SSoT + BTC/ETH fixtures, the Rust kernel (libm, de-mean, ddof=0, sigma^3) with a property battery proving time-reversal antisymmetry and scale-freedom, the 7-tuple wiring, the forward-only schema across all 4 sources, the <=1e-9 parity gate (shared helper), an in-Rust brute-force formula guard + the numpy cross-language independent leg, the ADR, the rrbicov:* mise tasks + slash commands, rrbicov:check-full GREEN, and a per-feature Attacker+Defender challenge (13 findings all refuted; documented the summation Wilkinson bound). Batch PR #544 updated to 3 implemented / 0 deferred. Next: feature 4/8 โ€” bar_ehlers_increment_asymmetry (skewness of bar-to-bar price changes; closed-form power sums).
