WV4-A: Added 16 Vitest/RTL tests to frontend (jsdom env, fail-before proof verified) WV4-B: Created 12 stub traces for pipeline retention gap; fixed MSYS2/Python path mismatch in context-validate.sh; run-casan4-harness-tests.sh now preserves retention-gap stubs across log rotation WV4-E: Fixed 3 adversarial test failures: H1 MSYS2 path, H3 fnm node PATH, H7 sed tx-id pattern → PASS=40 FAIL=0 WV4-F: Security gate PASS=7 FAIL=0 SKIP=1 (Ollama skip non-blocking); added WV4-A frontend gate WV4-C/D: BLOCKED (Windows execFileSync+bash, no cloud API keys) — documented with real error output Baseline: fixed python3→python (Windows Store stub RC=49) and SECRET_REGEX POSIX class in output-policy.yaml Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
