The scheduled dependency gate fails because Chordsmith Web and Pocket DAW lock the affected development dependency Vite 6.4.3. Raise both existing Vite requirements from ^6.3.5 to ^6.4.5 and lock 6.4.5. The only changed lockfile package is Vite; all other package versions and security gates are preserved.

Vite 6.4.5 includes the fixes for the advisories affecting <=6.4.3, including Windows launch-editor GHSA-587h-7wmj-h5pm / CVE-2026-112942. It also avoids the 6.4.4-only fs.deny regression, GHSA-8g5g-mxqh-grgj. This is development-tool exposure; the audit is not evidence of a shipped app compromise.

Raw npm audit --json --package-lock-only was captured before and after for each app. Each full audit changes from 1 high + 2 moderate vulnerable packages to 0 high/critical + 2 moderate packages. Both --omit=dev audits report zero vulnerabilities. The unchanged repository five-root dependency gate passes. The remaining findings concern development-only Vitest/@vitest/mocker: GHSA-qxg6-89mg-rqv8 and GHSA-xp26-3454-mjgp, with upstream 4.1.12 fixes; those packages are unchanged in this focused Vite repair.

Validation on Windows, Node 24.16.0 / npm 11.13.0:

• Security wrapper tests (6), tracked secret scan, security governance, five-root dependency audit and generated family governance pass.
• Chordsmith: 34 deterministic composer fixtures, 4 unit tests, lint, typecheck, formatting, size/single-file checks, Firefox/WebKit smoke (8), browser audio-quality checks (5), and build pass.
• DAW: full deterministic scope passes (108 files / 1,291 tests), including all 32 Windows-contract files; tooling tests (7), test inventory, version truth, release-candidate truth, native sound recipes, CI contracts and build pass.
• Chordsmith Chromium desktop + mobile emulation: 176 passed. DAW Chromium browser suite: 78 passed, 2 initially skipped because they require production workers. A separate run against the freshly built dist executes both production-worker checks: 2 passed (including five-minute decoded analysis and prompt cancellation).

The first browser-dependent attempts lacked the browser revisions required by the existing locked Playwright 1.63. Those attempts are retained separately in local evidence, then rerun after installing the required binaries. All browser servers bind to loopback. No installed-app, physical-device or microphone evidence is claimed. No application versions, runtime audio code, installers or releases are changed.

Exact-head hosted verification: CI run 40245011827 passed, including dependency/security, Chordsmith web, DAW frontend/release contracts, Windows contracts/Cargo fmt/tests/Clippy and the family gate. Five unrelated jobs were skipped by the unchanged scope planner (DAW browser E2E was covered locally as above). Both CodeQL scans also passed. Verified head: 2b3ff1f.
