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.

File Mentions
Ordinary out-of-scope @-mentions no longer get logged as denials; only escape-looking paths do.
What's wrong with this entry?
Anonymous. No account, no email.
What
A refused @-mention is now recorded as denied only when the path is absolute-ish, starts with ~, or contains a .. segment. Ordinary out-of-scope mentions return quietly.
Evidence
input_file_at_mention
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
