Error Analysis Worksheet

A spreadsheet or notebook layout for one Error Analysis cycle. Copy it into a sheet or DataFrame.

Rules: annotate ≥ 30 yourself before any AI suggestions · note what went wrong, not why · include non-model problems (missing features, UX) · write the first upstream failure.

Stop when new batches stop producing new or changed modes (see Theoretical Saturation).

Pivot (optional)

Pivot failure_mode × (feature | persona | channel) to find where failures cluster. For agents, also fill a Transition Failure Matrix.
