REA lets an AI agent reverse-engineer your shipped JavaScript or Electron app with no source code. REAShield hardens your build so that automated attack comes back empty: secret logic moves off-device or ships sealed, and what a static agent reads is stripped. Measured against the real REA on a bundled sample app: 6 protected tokens recovered before, 0 after. Not unbreakable: it defeats the automated attack and raises a human analyst's cost.
