Sonic
After picture lock — score beds, foley hits, diegetic space, and mix hierarchy without reopening the cut.
Educational module for Grok Imagine Cinematic Studio. Teaches picture-lock-first audio, mix hierarchy, sparse hero foley, native audio path, and Delivery handoff — pairs with the Sound craft page.

Role Card v4.5 — load after picture lock
PICTURE_LOCK_FIRST
Do not commit final score, stem masters, or loudness pass until Stitch picture lock is true.
Audio on a moving EDL wastes mix time and freezes the wrong cut.
SILENT_VALID
A intentional silent or music-only montage is a valid deliverable — not a failure mode.
Quota and stills-first often ship without full native audio. Intention beats noise.
MIX_HIERARCHY
Protect story intelligibility: VO/dialogue > hero foley/SFX > score > atmos. Duck lower layers under higher.
Everything at full level is not cinematic — it is soup.
SYNC_TO_BOUNDARY
Land hard hits on cut points, motion peaks, or button frames — not arbitrary mid-clip spam.
Picture already defines rhythm; fight it and the cut feels broken.
LEAVE_POCKETS
Score and atmos need quiet pockets for button moments and breathing room.
Wall-to-wall beds flatten emotion and bury picture beats.
DIEGETIC_LABEL
Label every element diegetic / non-diegetic / hybrid in the sonic brief.
Unlabeled layers get mixed as score when they should live in the room.
HERO_FOLEY_ONLY
Foley only hero contacts that sell weight or story — not every footstep.
Over-foley makes AI motion look more artificial, not less.
PLATFORM_LOUDNESS
Target platform loudness early (web / social / trailer) and leave headroom for peaks.
Hot masters clip and get crushed by platform normalization.
RIGHTS_CLEAR
Only use clearable / original / licensed beds. Note provenance on the handoff packet.
Pretty illegal stems kill delivery faster than a soft mix.
SONIC_HANDOFF
Export mix brief + stem list + picture-lock stamp into Delivery before client export.
Downstream polish and delivery need audio state, not vibes.

Lesson 01
Why sonic is a gate
Audio after picture lock sells weight and emotion — or exposes a draft cut.
- Score cannot fix a broken EDL; it can only polish a locked one.
- Silent-with-intent beats random bed spam.
- Activate Sonic Architect when the sequence has a locked spine.
Drill
Name one teaser that ships intentionally silent vs one that needs score.
