http-cache-semantics <=4.2.0 has no patched release; astro (via starlight) depends on it. astro uses it only to cache remote images during `astro build`, and the site ships as static assets behind a worker that does not import astro, so the path never runs for a visitor. pnpm-workspace.yaml's auditConfig.ignoreGhsas sets that one advisory aside, with its reasoning and dates; a step in the audit job fails once the recheck date passes. The audit level is unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GHjaH1Vt2dVLWU68iz8tFq

Why
The
auditjob fails on GHSA-ch52-4w7c-c8xp (high, http-cache-semantics max-stale handling can disclose cross-user cached responses). Vulnerable<=4.2.0, no patched release; astro 7.3.x (latest stable 7.3.5) depends on^4.2.0. Path:site/nyuchi-docs-search->@astrojs/starlight->astro->http-cache-semantics.Exploitability here
astro imports the package only in
dist/assets/build/remote.js(fromcore/build/static-build->generate), to cache remote images whileastro buildruns. The site is static output served from Workers static assets behindsite/src/worker/gate.ts, which imports onlyjoseand local modules, not astro. The vulnerable path runs only in our own build, never for a visitor.Change
pnpm-workspace.yaml:auditConfig.ignoreGhsas: [GHSA-ch52-4w7c-c8xp], with the reasoning, the date it was added (2026-10-03) and the recheck date (2026-11-03) in comments. pnpm's own per-advisory ignore;--audit-level=highis unchanged, so any other high advisory still fails.build.yml: a step in the audit job fails once 2026-11-03 passes, so the exception cannot outlive its reasoning.Tested locally:
pnpm audit --audit-level=high-> "1 high (1 ignored)", exit 0;pnpm install --frozen-lockfileunaffected.Same treatment as nyuchi/learning#63.
