Report #42509

[frontier] Original user intent is corrupted after 5\+ handoffs between specialized agents \(planner → coder → reviewer → tester\) in multi-agent swarms

Implement Intent Provenance Headers \(IPH\): attach immutable metadata to all artifacts containing the original constraint hash and decision rationale; agents must read and 'sign' headers before execution, ensuring intent survives chain length

Journey Context:
The standard pub/sub or message-passing between agents assumes lossless transmission. In practice, each agent 'reinterprets' the task through its own fine-tuning, dropping nuances \(the 'telephone game' effect\). The Task Context Object \(TCO\) pattern treats the task as a smart contract: it contains the objective, the constraints \(hashed\), and the acceptance criteria. Agents don't 'receive' a task; they 'sign' the TCO, verifying they can meet the constraints. This borrows from the Model Context Protocol's concept of resource provenance but applies it to inter-agent communication. The critical insight is that intent must be externalized from the agent's KV cache \(which gets wiped on handoff\) into the artifact itself.
