…re-seal specs/numeric: added negative_control_refutes_* tests to 15 specs (tnf4-1024, tnf_threshold_gate, golden_sieve, ocp_mx, posit_ladder_control, lucas_accumulator, zphi_alu). Coverage: 212/375 -> 227/375 (+15). specs/t27os: added negative-control tests to 27 specs and re-sealed all. Coverage: 506/630 -> 535/635 (+29). Remaining gaps: - specs/numeric: 148 gaps (seal NO-MATCH on paper_claims + sha256 family, no-issue on ~67 specs, unmeasured on ~11 specs) - specs/t27os: 100 gaps (no-negative-control on ~20, no-issue on ~48) Closes #12913

…hree t27os specs (Refs #12972) (#13344) * specs(numeric,t27os): fix sha256 K table and micro5 oracle, restore three t27os specs, clearing five coverage reds (Refs #12972) The coverage job has been red on master since #13335 with five seals: - numeric_Sha256.json [tests-fail]: two round constants were off by two (K[58] 2227730450 -> 2227730452 = 0x84c87814, K[63] 3329325296 -> 3329325298 = 0xc67178f2), and the message schedule summed the wrong words. The FIPS abc, empty and long vectors now pass 3/3 under t27c test-report (vacuous 0) and t27b. - numeric_Sha256Micro5.json [tests-fail]: the oracle values were wrong; 4/4 pass now. - t27os KeysyncScopeProbe, T27osHdmiGrabMain, T27osHiveFeedAcceptance [stale]: #13335 added an `assert 1 == 1` placeholder test to each spec without re-sealing. The placeholder asserts nothing, so the specs go back to their sealed text instead of a re-seal. Both numeric seals were re-saved without --force; neither spec has a twin. Seven baselined seals that hold again are dropped from seal_baseline.txt (the CI NOTE names them). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * specs(tri/shootout): four shootout specs generate again, clearing emit-bitexact (Refs #11275) emit-bitexact on master reported "4 spec(s) newly do not generate with any backend". Each fix keeps the spec's meaning; gen-c now exits 0 on all four (t27c built from master, run in a T27 OS shell pane). - option1/2/3: `;` comment lines inside fn bodies are a parse error there ("Unexpected token in expression: Semicolon"); they are `//` now. A stray `};` after each fn and test is `}`. - improve.t27: `use tri::t27b::zig_like_optimization_plan` names no spec and nothing in the file used it; removed. - improve.t27, option3: `bench::measure_all_languages()` does not exist in bench.t27 and `bench` is a keyword in expressions. Both now read the one measured row bench.t27 exports, MEASURED_T27B_BASELINE, through the symbol-level `use` acceptance_matrix.t27 already uses. - Em dashes in three header comments are `--` (L3 ASCII). The four still do not pass test-report: they call an undeclared LOG, so the Zig build is BLOCKED, as it was before (they did not parse). The spec-guards affected-spec step measures both trees, so BLOCKED on head against BLOCKED on base is no regression. None of the four has a seal. dupe_scan: no new group. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * specs(tri/shootout): take master's improve and option3, superseded by #13305 (Refs #11275) Master's #13305 (Closes #13303) fixed the same emit-bitexact red in the four shootout specs with a local measure_all_languages stub. option1 and option2 already match master byte for byte; this sets improve.t27 and option3_competitor_analysis.t27 to master's text so the next commit can merge master without a conflict. The two commits are one merge of master. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
