Report #62493

[synthesis] Agent treats partially created or modified artifacts as success, building subsequent steps on compromised foundations that appear valid but contain critical omissions

Implement atomic transaction semantics for agent state changes \(all-or-nothing commits\); use checksum or hash verification to ensure artifacts match intended specifications before proceeding; implement idempotent operations that can be safely retried without side effects from partial completion

Journey Context:
The dangerous pattern occurs when an agent performs a multi-step operation like 'create a React component' and successfully writes the file header and imports, but fails on the component body due to token limits or errors. The file exists, has valid syntax, and passes basic linting, but is functionally useless. Because the file exists, subsequent steps \(importing this component, writing tests\) proceed as if the dependency is satisfied. The failure only manifests much later with confusing 'undefined' errors or missing functionality. The fix requires treating file system operations \(and API mutations\) as transactions that must pass semantic validation \(e.g., AST parsing, test execution\) before being committed to the main state.
