[s2d2-agent]

s2d2 dependabot evidence (run sa-2026-10-29-7e1f25f1)

Decision: SAFE. dev-only minor, CI green.
Packages: browserslist 4.21.5 to 4.29.4
Scope: dev only, minor bump, tier 1.
CI: 2 checks, 0 failing, 0 pending at classification.
Security update (alerts: high).
Local verification not required for this class of bump.

Awaiting merge approval from Guillaume in the Security Autopilot thread. This is an evidence note, not an approval.

[glebedel]

s2d2 verdict: SAFE. lockfile-only dev transitive; CI green, not imported.

• CI on 13388ad: green
• Breaking changes reaching our code: none (browserslist 4.21.5->4.29.4 is minor fixes; also moves caniuse-lite, node-releases, electron-to-chromium)
• Call sites: not imported (only via @babel/helper-compilation-targets ^4.21.3 and update-browserslist-db)
• Security: open Dependabot alert(s), max severity high

react-hub CI runs npm ci, lint, test (=lint) and a semantic-release dry run on the head only; rollup build is not run. Lockfile-only (+101/-56). Parents accept ^4.21.3 so the range holds; new transitive baseline-browser-mapping needs node>=6. Check "build (22.23.4)" passed on 13388ad.

Requested by guillaume@stackone.com, Security Autopilot run sa-2026-11-05-ae4daeb6. s2d2 never approves PRs.
