The 2026 development
Google previewed an Antigravity swarm feature with parallel workspaces, specialised responsibilities and checking agents.
The governance gap
A planner that can spawn workers and checkers can also spawn a worker with more authority than the planner holds, or let a checker approve its own sibling. Parallelism multiplies the places where scope can drift.
Where CAIN-42 fits: Moat 2 — Security-Context Continuity
Core question: Does authority survive every boundary? Identity, scope and delegation are carried across tools, agents, memories and systems.
Make delegation attenuation structural: a child capability can only narrow the parent's scope, lifetime and resources. CAIN's execution-chain capability type refuses a handoff that widens scope or extends life, regardless of what the planner says.
How the wiring works
- Issue the planner a capability with explicit scope, destination and expiry.
- Derive each worker capability from the parent, allowing only narrowing.
- Require the checker to be a different identity from the worker it checks.
- Record the delegation tree and verify it after the run.
What is real today
LIVE A public route in this deployment exercises this mechanism today, within its stated scope.
The hosted demo proves attenuation and collusion checks on fixed presets. It does not operate Antigravity or any Google product.
