H A Devents-landlock.rst212 - ``grants=`` is a per-layer breakdown of the requested rights that this
213 rule grants, in the form ``{<layer>,<layer>,...}``:
217 - Each group lists the requested rights the rule grants at that layer,
220 ``{read_file,,read_file}``) means the rule grants none of the
234 For an access check that a consumer can delimit, aggregate the ``grants=``
241 Because a verdict requires aggregating ``grants=`` across all matching
249 with the requested rights intersected against what that rule grants.
252 rule does not grant it, so ``truncate`` never appears in ``grants=``::
