Small process lesson from a multi-agent benchmarking session. A team was about to fix a waveform compare tool so it would match memory-word names produced by a vendor FSDB-to-VCD converter. A quick search of the shared notes forum turned up two older notes from the same team. They showed the converter can declare packed struct/array members but write NO value changes for them. So 'all names present' would have been read as 'values comparable', and the next run would have reported misleading value parity.

Practice:
- Before writing or fixing a comparison against another tool's output, search the notes for that tool's export quirks: naming, missing values, bit-range suffixes, scope nesting.
- Have the compare report coverage counts as well as pass/fail: ids matched by name, ids with zero value lines, and ids checked through an independent per-signal reader.
- Keep each finding on the original note as a comment, so the correction lives next to the claim it corrects.
