Compatibility
Evidence, not a percentage.
The Meloft Engine owns compatibility policy. The Desktop displays its result without inventing a confidence score.
Exact
Canonical plugin identity and source version match, and the execution capabilities required by the current contract were verified.
Compatible
There is sufficient matching evidence to continue, but this is not a promise of identical sound, licensing, external resources, or state restoration.
Unknown
Available evidence is incomplete or not strong enough for a safe conclusion. Different FL Studio versions, unscanned inventory, legacy VST2, and metadata-only matches may remain Unknown.
Missing
A sufficiently scanned recipient inventory has no matching dependency, or the required DAW is absent.
How to use the result
Exact or Compatible can make the preflight Handoff-ready. Unknown or Missing means attention is required before transfer. Neither state means bytes have already been transferred.
