What a summariser heard, two minutes at a time.
Google’s NotebookLM makes a two-minute brief from whatever sources it is handed. Each brief carries one argument, so a stack of them reads like a census: the lines it got right show what our sources say clearly, and the lines it got wrong show where our sources still compress badly.

The errors repeat. A brief that promises a cage read a source that names a boundary and stops before the record. A brief that sells 99.85 % as savings read a rung-2 number printed without its counterfactual. Each recurring class points back at a sentence in our sources to fix, and the next brief made from the fixed sources is the check.

Sufficient for: what Google NotebookLM said in each two-minute brief it made from our sources, verbatim, with its timestamp, the day it was made and the file it came from. Not sufficient for: what our sources say — a brief is a projection of the notebook, never the notebook. Percentages are of the transcript's lines: ✅ quoted as said, ✏️ quoted beside the sentence we would sign, ❌ corrected. Each address is the first eight hex of the audio file's md5. The same summariser's pictures, read the same way, are at /infographics.
