DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
Plugin cache version folders nest under marketplace and plugin
Under the hood

Plugins
Cached plugin versions now nest under marketplace and plugin folders.
What's wrong with this entry?
Anonymous. No account, no email.
What
Cached plugin versions now live at cache/<marketplace>/<plugin>/<version> because the directory and the sanitized version segment are computed separately. The per-stage error reasons for the path containment check moved from a switch into a lookup table of the same strings.
Evidence
plugin cache version parent not contained before relink
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
