[synthesis] Agent operates on wrong target but gets success signals that hide the original misrouting

After every file write or tool execution, inject a verification step that checks target identity \(not just operation success\). For file operations: verify the path matches the original intent. For API calls: verify the resource ID. Make target-identity verification a separate mandatory step.

Journey Context:
When an agent uses a slightly wrong file path \(e.g., /src/utils/helpers.py instead of /src/core/helpers.py\), subsequent operations all succeed—the file is read, modified, written, and even tests may pass against the wrong file. Each success signal actively masks the original error. The synthesis: the compounding isn't linear—it's exponential, because each success makes the agent less likely to question its trajectory. By the time the error is discovered, the agent has built an entire consistent-but-wrong world model. This is distinct from simple wrong-path bugs because the success signals are the real problem—they're actively misleading. The agent's confidence monotonically increases while correctness has already diverged.
