One canonical store with derived selectors

Not:
• ad hoc local state in each panel
• copied arrays
• parallel models for timeline vs grid vs layouts

Instead:
• one canonical project store
• normalized entities
• selectors / derived view models per workspace

Example mental model

Canonical entities
• sounds
• events
• sources
• layouts
• constraints
• sections
• performance mappings

Derived selectors
• composeTimelineView
• optimizeGridView
• candidateLayoutCards
• practicePlaybackView
• soundsBrowserItems

That way:
• every surface is reading from the same truth
• different modes can still present different derived views
• renames and assignments propagate everywhere

Product rule I would enforce

Nothing should store duplicated display data if it can reference an entity ID

For example:

Bad:
• timeline row stores "Hat 1"
• grid pad stores "Hat 1"
• layout card stores "Hat 1"

Better:
• all of them store soundId: "snd_hat1"
• the display name comes from canonical sound state

That one discipline will save you a lot of pain.
