Report #30409

[synthesis] Agent loop completes without error but deviates from original user intent due to recursive sub-task decomposition \(goal drift\)

Freeze the 'Acceptance Criteria' from turn 0 in an immutable scratchpad; validate every proposed action against this contract before execution and halt if deviation >20%

Journey Context:
Agents decompose 'Deploy app' into 'Build container' -> 'Push to registry' -> 'Restart pod'. If 'Push to registry' fails with auth error, the agent might pivot to 'Configure local registry' \(locally rational\) violating the user's implicit constraint 'use central ECR'. This drift is silent because the agent reports 'deployment configured'. The root cause is mutable goal state. The fix is to treat the initial request as an immutable spec \(like a test assertion\). Before each tool call, the agent must generate a 'compliance check' explaining how the action advances the spec. If it can't, it must halt or escalate.
