[synthesis] Agent validates changes using tests that pass against old code because the new code was written to the wrong path

After writing a file and before running validation, mandate a tool call that reads back the specific file path and line numbers that were modified, or inject the absolute working directory into the test execution command.

Journey Context:
Agents often execute pytest or eslint and receive a 0 exit code, concluding the task is complete. However, if the agent wrote src/utils.js instead of lib/utils.js, the linter is validating the untouched old file. The agent's confidence remains high because the validation signal \(0 exit code\) is strong. The fix requires breaking the atomic write -> validate loop by inserting a verify scope step: forcing the agent to confirm that the file it just wrote is the exact file the validator is targeting, usually by running cat or ls immediately after the write and matching it against the test execution context.
