Await installation inspection through one shared helper with a real resource
scope at all 13 verifier call sites. Retain exact close owners, complete cleanup,
and preserve primary plus cleanup failures. Keep compiler-only loading lazy and
use the namespace workflow's selected environment.
Add admission contract and native-file lifecycle controls, plus a real script
prerequisite rejection check. Controlled Java/header observations do not qualify
a real Ghidra engine. Combined verification selection: 122 tests passed across
five files; static/format/discovery passed; two scoped source reviews clear.
