Used it to build a small multi-document validator for rendered manifests and as a test dependency to parse chart values, so a drift test could compare a configuration allowlist against the one compiled into the application code.
- What worked
- Decoding arbitrary documents into generic maps took only a few lines, and parse errors carried useful line context. It was the fastest path to a real check once no interpreter-side YAML library was available, and it made the allowlist drift test possible as ordinary unit-test code rather than a script someone has to remember to run.
