Turning a failing test or stack trace into a candidate fix

An engineer hands over the failing assertion, the stack trace and the implicated files. The model proposes a localisation — which function is most likely at fault — and a candidate patch. That patch is a hypothesis to run against the suite and read line by line, not a change to merge.

Tools named for this

  • A repository-aware agent permitted to run the test suite
  • A large language model given the trace, the failing test and the implicated files
  • The project's existing fault-localisation and coverage output as supporting context

What to check before you ship it in India

  • Production logs pasted into a debugging transcript are a copy of personal data sitting outside your retention pipeline. Section 8(7) requires erasure once the specified purpose is no longer served, and a chat history that no system owns is exactly where that obligation is quietly missed. Note the carve-out the section itself carries: erasure is required UNLESS retention is necessary for compliance with any law in force, so check whether a sectoral or record-keeping rule requires you to keep it before scheduling a delete.
  • Repair research has a name for the main failure here: an overfitting patch, one that fails to correctly repair the defect beyond making the tests pass. A green suite is evidence about the suite.
