From 835f25d324cdc95e33d2461d80670862fa09c6ce Mon Sep 17 00:00:00 2001 From: Matt Jones <47545907+SoundMatt@users.noreply.github.com> Date: Sun, 26 Jul 2026 05:53:27 -0700 Subject: [PATCH 1/4] =?UTF-8?q?feat:=20v0.5.35=20=E2=80=94=20HLR/LLR,=20to?= =?UTF-8?q?ol=20qualification,=20MC/DC,=20V&V=20independence?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Feature 1 (REQ-HLR001–004): Add parent_id to req_t; compute_hlr_llr() detects orphaned LLRs and uncovered HLRs; --strict-hlr-llr CLI gate (exit 1 on violations); JSON hlrllrSummary + parentId in output; text/md HLR/LLR summary line. Tests: test_hlr_llr.c (8 tests). Feature 2 (REQ-QUAL003, REQ-QUAL006): --qualification-method/--qualifier/ --record-uri flags; qualification_badge() helper; badge shown in text and JSON output. Tests: test_qualify_vv.c (9 tests, covers F2+F4). Feature 3 (REQ-COV015): --mcdc-file (LLVM MC/DC JSON) and --mcdc-threshold flags; parse_mcdc_json() parser; condition covered iff covered_true_count>0 AND covered_false_count>0; gate on threshold; JSON mcdcReport field; MC/DC-file-only mode (no lcov needed). Tests: test_mcdc.c (8 tests). Feature 4 (REQ-VV001, REQ-VV004): --implementation-author/ --independent-reviewer/--independent-test-executor/--achievable-asil flags; independence_status() helper returns independent/self-reviewed/ unqualified; fields in JSON output. Also: macOS/BSD optreset=1 fix in cmd_coverage and cmd_qualify to ensure correct getopt state reset across multiple calls in same process. 9 new requirements in .fusa-reqs.json. 3 new test files (25 tests). Total: 37 tests, all passing. Closes #48, #49, #50, #51.

The next getopt_long call immediately dereferences that stale pointer => SEGFAULT on ubuntu-22.04 with both clang and gcc. Fix: add `#elif defined(__linux__) optind = 0` to the existing platform reset block in cmd_coverage.c, and add the full platform block to cmd_trace.c which had no guard at all. glibc resets nextchar (and all other internal state) when it sees optind==0 on entry.
