…emaining lift question (no κ claim) Package research/three-total-decoders (T = 3 exact decoders under #446 Theorem C; builds on #1590, cites #2031). PROVEN: Lemma SCC, Lemma Peel, minimal-counterexample structure, Theorems M1 and U, the F2S identity, tied_min cost = 12 (exchange proof, 217 optima, all lift), Lemma W', Theorem 9.3. CHECKED: certificate limits (all stop at 11 on tied_min), exact counterexamples (whole-matrix TU at v = 9; joint block-TU signing at v = 7 and 10, with (A) holding on each; non-regular minimisers; K22-free without TU signing; PP false), and 102 explicit same-support rational lifts for the minimisers tested on the no-joint instances. OPEN: (A) at T = 3; its core (Q <= F2) (min Q-cost over rational B' on incidences plus diagonal <= min F2 cost); same-support lifting (G1') is a witness form only. Hesse tests over Q(w): none found below v. No kappa claim. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Follow-up to the merged #1590 (
research/root-unit-decoder-lemmas). Its review recorded the D5 T = 3 UNSAT proof as "not shipped or replayed". This PR adds onlyresearch/root-unit-decoder-lemmas-drat/:d5-t3-drat-v1:f5e75d3b…7796;s VERIFIED;fetch_and_check.sh. Quick mode checks downloads, hashes and the CNF pin.FULL=1builds drat-trim at a pinned commit and checks the core proof (about 3–6 min).FULL=2also checks the original proof.SHA256SUMSand a README.Recorded check:
FULL=1, macOS arm64: all hashes PASS, CNF pin PASS, drat-trims VERIFIEDin 178 s.Scope: this certifies CNF unsatisfiability only. That the CNF encodes the decoder question remains the merged package's audited claim (
evidence/D5-AUDIT.md). No change to the merged package, and no new mathematical claim.Prepared by DreamingOfClouds with Claude Opus 5.5 (Anthropic), via Claude Code; Apache-2.0.
