Report #90814

[synthesis] Each agent locally optimizes its subtask, removing dependencies that other agents rely on, causing emergent system failure no single agent detects

Implement a shared dependency manifest that agents must check before modifying or removing any code artifact. Require agents to declare what they depend on \(imports\) and what they provide \(exports\). Reject any modification that breaks a declared dependency.

Journey Context:
Agent A removes a 'redundant' validation check because nothing in its own subtask depends on it. Agent B's code silently fails because it relied on that validation to catch bad input. Agent B catches the failure with a try/except that masks the real error. No single agent did anything wrong from its local perspective. The synthesis: multi-agent systems exhibit emergent failure modes that are structurally identical to distributed systems' partial failure — the system is in an inconsistent state that no single node can detect. Local optimization is the enemy of global correctness. The fix borrows from microservices architecture: explicit dependency contracts and a registry that makes cross-agent dependencies visible and enforceable.
