Enum Provenance 

pub enum Provenance {
    Literal,
    Glob,
    Variable,
    ProcessSub,
    CommandSub,
}

How statically bounded a command argument’s value is.

Derived purely from the tree-sitter-bash AST node kind of the argument — no heuristics, no disk I/O. Controls whether path_scope is computable and feeds every_arg/any_arg quantifiers in the policy DSL (R295-F9).

Ordinal order is severity: CommandSub > ProcessSub > Variable > Glob

Literal. The Ord impl enables the fold in arg_provenance.

Variants

Literal

Fully static — value known at parse time (Word, RawString, Number, …).

Glob

Unquoted Word containing *, ?, or [ — expands to an unknown set of paths.

Variable

$VAR, ${…}, $((…)) — value unknown at gate time.

ProcessSub

<(cmd) process substitution — data flows from a subprocess file descriptor.

CommandSub

$(cmd) command substitution — injection point; result may contain arbitrary text.
