The Briefing: Top-tier music supervisors in 2026 are no longer just auditing your Master. They are auditing your stems for "Ghost Files" hidden unrendered plugins or unsynced MIDI that can break a project in the final dub.
The Reality: In a high-stakes film suite, time is the most expensive commodity. If your stems don't lock to the sample clock on the first try because of a side-chain dependency or an unrendered VST, the editor won't fix it. They will move to the next track on the shortlist.
The Move: Implement a Hard-Render policy today. Every stem must be a consolidated, continuous audio file from Bar 1. No active plugins. No MIDI. No dependencies.
