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.
Memory store descriptors gain visibility and prompt-index fields
Under the hood

Memory
Memory store records can now carry a visibility setting and a prompt index path.

What
The schema describing a memory store now carries a path, a read-write or read-only mode, a kind and a grouping id, plus optional visibility and prompt-index fields bounded to 64 and 512 characters. Both new fields fall back to undefined on bad input, so a malformed value degrades instead of failing the whole parse.
Evidence
grouping_id
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
