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 v2.1.246

Disabled settings files no longer feed rules into the sandbox

You'll notice

Sandbox

Rules from settings files you disabled no longer sneak into the sandbox policy.

sandbox.filesystemsandbox.credentials
What

When building the sandbox policy, Claude Code now checks whether each settings source is enabled. Permission rules and sandbox.filesystem entries from a disabled source are skipped and logged; disabled project and local sources also have their sandbox.credentials entries dropped. Previously those entries were applied anyway.

Details
  • Applies on every sandbox policy build, with no flag to restore the old behaviour.
  • The skip is recorded at info level, naming the disabled source.
Evidence

Sandbox: ignoring permission rules and sandbox.filesystem entries from disabled setting source

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