Quoted whole from the 2017 thread, since the article author asked to merge it
and never did. Verified line by line against the thread cache. Covers sample
size from a cumulative-mean plot, KLD/Dice on unbalanced data, augmentation
bounded by feature std, dummy metrics, jumpy validation loss, testing the
framework itself, activation swaps, and loss-curve shapes.
An /abs/ link is a stub: it costs a second lookup before anyone can check the
quote, and it is what let abstract-only caches look sourced. 77 links across
the skill files and 4 cache headers. Verbatim source bodies untouched, their
reference lists are the authors' text.
