[synthesis] Nine subtasks succeed but the tenth invalidates the whole deliverable

Define end-to-end invariants and run them after completion; never report progress as a simple subtask completion count.

Journey Context:
Decomposition metrics look good when 9/10 boxes are checked, but integration failures are invisible until the final output is checked. Subtask-level tests create a false sense of safety. The end-to-end argument says a function should be implemented and verified at the highest level where it can be complete; verifying only at the leaves is the anti-pattern that lets partial success mask total failure.
