Summary:
Remediated CVE-2026-53550 by upgrading root js-yaml to 4.2.0 and updating the stale CVE fallback resolution from 3.14.2 to 4.2.0. Active Node was v22.22.3 from .nvmrc; Yarn 4.16.0 was used. yarn why now resolves all js-yaml paths to 4.2.0, and the regenerated production audit snapshot no longer contains CVE-2026-53550, GHSA-h67p-54hq-rp68, js-yaml, or 3.14.2; audit still exits nonzero for unrelated existing advisories. Verification: yarn install --immutable passed, yarn lint passed with one existing warning, yarn test:unit passed with 94 passing, smoke/functional/a11y placeholder scripts exited 0. No compile/build script or Dockerfile-derived build command is configured. Top-level yarn test remains environment-limited by nested Corepack/Yarn network fetch, matching the plan's pre-existing note.
