…misconfig Templates/examples now deny both subagent-spawning tools; new policy.CheckSubagentMisconfig warns at MCP+hook startup (AFLOCK_STRICT=1 refuses) when Task/Agent is permitted without sublayouts. Re #100.
Stamp predicate.trustBoundaryCrossing for subagent spawns; verify warns when a session delegated work outside aflock's enforcement plane. Re #100.
Cover Task vs Agent, deny precedence + glob matching, MCP-vs-hook enforcement limits, and safe delegation patterns; correct the stale sublayouts status. Re #100.

Closes #100.
Subagents spawned via
Task/Agentuse Claude Code's native tools, which bypass aflock. Real-time enforcement of those inner calls is an upstream gap (claude-code#27661 / #34692, both closed-not-planned), so this PR hardens the boundary aflock can control:TaskandAgent(distinct tool names; deny one ≠ deny the other).policy.CheckSubagentMisconfiglogs a WARNING at MCP + hook startup when a policy permitsTask/Agentwithout declaring sublayouts;AFLOCK_STRICT=1refuses to start.Task/Agentattestations are taggedtrustBoundaryCrossing;aflock verifyflags sessions that delegated work out of the enforcement plane.Out of scope (noted in code/docs): real-time enforcement of a subagent's inner native calls (upstream), and protected-file tamper detection (follow-up). Tests: CheckSubagentMisconfig matrix + attestation-tag tests; suite green.
