Sandbox filesystem.disabled description corrected on credential masks

Settings docs now explain that masked credential files survive a relaxed sandbox filesystem policy while denied ones do not.

What

The settings schema text for skipping filesystem isolation now separates two kinds of credentials.files entries that behave differently under a relaxed filesystem policy.

Details
  • Deny entries in credentials.files are dropped and pin the setting to managed settings.
  • Mask entries are implemented as sentinel binds, survive the relaxed filesystem policy, and do not pin the setting.
  • Env scrubbing is likewise independent of the filesystem policy.
Evidence

do not pin it — env scrubbing and sentinel binds are independent of the filesystem

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