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.

Claude Code v2.1.247

Files provided to a session are stat-able even when not served by storage

You'll notice
Useful2 Signal2
Elsewhere

Files handed to a session can now be inspected directly on disk when storage can't serve them.

What

When a file that was placed into a session cannot be inspected through the storage layer, Claude Code now re-resolves it as a system, workspace or home path and inspects it directly on the host, rather than failing. Only a file that is genuinely unreadable still raises an error.

Details
  • The storage lookup returns an explicit "not served" result instead of throwing, which is what enables the fallback.
  • Modification times read this way feed the checks that detect a file changing under you.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
