Limits
O’Neill names Cartridges in the panel. His separate account of forgetting under repeated model updates concerns unpublished team work; stale circumstances and forgetting during training are different problems.
Editorial test, not a stated concession
Change one important fact after an initial investigation. Check whether a returning assistant updates the affected advice, preserves useful earlier work and explains what changed.
supports
O’Neill contrasts durable technical discoveries with knowledge about changing workplaces, and discusses Cartridges as one possible way to specialize a model.
context
Cartridges studies reusing a compact representation of a corpus; its tested savings do not establish reliable updates to changing organizational knowledge.
