Report #60752

[synthesis] High-level task shows progress metrics \(files changed, lines edited\) while functional correctness is violated

Gate step completion on functional validation \(tests pass, imports resolve, executable runs\) rather than file operation success; implement rollback on functional check failure.

Journey Context:
Traditional software engineering distinguishes 'build success' from 'test success,' but agent frameworks often conflate 'file edited successfully' with 'task completed successfully.' The synthesis reveals a 'compilation bias': agents assume edited code works if syntax is valid and file operations return success, ignoring semantic correctness. This creates 'green-light failures' where 80% file modification success masks 100% functional failure \(e.g., broken imports\). Single sources suggest 'add tests,' but miss the architectural requirement: agents need 'functional validation gates' between steps, not just at the end. Tradeoffs: running tests between steps is slow; not running them risks cascade failure. The synthesis shows that without 'semantic rollback' \(reverting when functional checks fail\), agents compound errors because they treat partial file success as a solid foundation for next steps.
