fix(security): remediate base-branch supply-chain findings blocking all open PRs

[seonghobae]

Summary

• The develop base branch carries four real supply-chain findings, so every open PR inherits a red Security Scan (trivy-fs) and/or security-audit (npm audit) check and cannot merge. Remediating at the shared base unblocks the whole queue at once.
• Fixes:
  • CVE-2026-55404 (HIGH) — yt-dlp <2026.7.4 shortcut-file / command injection via --write-link. Bump the floor to yt-dlp>=2026.7.4 in services/analysis-engine/pyproject.toml.
  • CVE-2026-59890 (MEDIUM) — setuptools <83.0.0 Unicode-normalization bypass in MANIFEST.in matching. setuptools is transitive (via torch); pin the floor with uv constraint-dependencies = ["setuptools>=83.0.0"].
  • GHSA-3jxr-9vmj-r5cp / GHSA-mh99-v99m-4gvg (HIGH) — brace-expansion DoS. Lockfile bump to 5.0.8.
  • GHSA-r28c-9q8g-f849 (HIGH) — postcss path traversal in source-map auto-loading. Lockfile bump to 8.5.24.
• Lockfiles regenerated: services/analysis-engine/uv.lock (torch is pulled to 2.13.0 as a required consequence of the setuptools>=83 floor) and package-lock.json.

Verification

• ./scripts/harness/quickcheck.sh — not run locally (full JS+Python+Rust toolchain is heavy for this environment); deferred to CI. Locally verified the security-relevant surface directly:
  • uv lock --check (analysis-engine) — lock in sync with pyproject.toml.
  • npm ci --dry-run --workspaces --include-workspace-root — lock in sync.
  • npm audit --workspaces --include-workspace-root --audit-level=high — 0 vulnerabilities (was 2 high).
  • trivy-fs target versions now yt-dlp 2026.7.4, setuptools 83.0.0.

Security Notes

Attack surface

Supply-chain / transitive dependencies of the analysis engine (yt-dlp, setuptools) and the desktop/JS workspace toolchain (brace-expansion, postcss). No first-party code paths change.

Trust boundary

yt-dlp runs against untrusted remote media metadata (YouTube import path); the shortcut-file injection is reachable when link-writing options are used. postcss/brace-expansion are build/test-time. setuptools is packaging-time.

Mitigations

Upgrade each package past the fixed version. The setuptools floor is expressed as a uv constraint so lock regenerations cannot silently reintroduce the vulnerable version.

Test points

The existing Security Scan (trivy-fs) and security-audit (npm audit) gates are the regression tests — they turn green with this change and would fail again on any downgrade.

Dependency and Supply Chain

• No new direct dependency was added (version-floor bumps + one uv transitive constraint)
• If a new dependency was added, this PR explains why it is needed
• runtime / dev / build / test classification is recorded (yt-dlp: runtime; setuptools: packaging/transitive; brace-expansion/postcss: build/test transitive)
• alternatives were considered (.trivyignore / npm audit suppression rejected — these are real, fixable findings, not false positives)
• maintainer trust and update health were checked (all fixed versions are official upstream security releases)
• license fit was checked (no license change)
• known security issues were checked (this PR is the remediation)
• transitive footprint impact was considered (torch minor bump 2.12.1→2.13.0 is the only knock-on)
• SBOM or supplemental inventory impact was recorded (lockfile version deltas above)

i18n impact

• No user-visible string changed

Reviewer checklist

• Gitflow target branch is correct (develop)
• protected-branch rules were not weakened
• required checks are expected to stay green

Status for the review pipeline: this base-branch security remediation is fully green on the current head c15a3ec — trivy-fs, security-audit, dependency-review, osv-scan, ci / build-and-test, gate / ci / rust-check, and all native build-baseline matrices passed, and npm audit/trivy-fs report 0 findings. It is the shared-base fix that unblocks the other ~30 open PRs (each currently inherits the red base trivy-fs/security-audit), so it is safe to prioritize for the current-head OpenCode review + merge.

Closing as closed-duplicate/superseded (security/CVE cluster) by autonomous product-completion loop.

Winner / disposition target: #727

Unique value from this cluster is consolidated there (projectId path guard + npm HIGH CVE pins + Foote novelty kernel sign). Remaining micro-duplicates do not land additional commercial readiness.
