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.
When policy limits are fetched and no restrictions apply, Claude Code now preserves an explicit cached empty result instead of treating it like a deleted cache file. This should reduce noisy policy-limit cache churn in environments with no active restrictions.
Evidence
Policy limit cache message (search for "Policy limits: No restrictions (cached empty)")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
