## Summary - Remove 3 completed migration feature flags: `IS_ATTACHMENT_MIGRATED`, `IS_NOTE_TARGET_MIGRATED`, `IS_TASK_TARGET_MIGRATED` — these were already enabled by default for all new workspaces via `DEFAULT_FEATURE_FLAGS` - Delete all upgrade command directories for versions <= 1.18 (`1-16/`, `1-17/`, `1-18/`) along with their module registrations, removing ~6,600 lines of dead migration code - Simplify frontend utility functions (`getActivityTargetObjectFieldIdName`, `getActivityTargetsFilter`, `getActivityTargetFieldNameForObject`, `generateActivityTargetMorphFieldKeys`, `findActivitiesOperationSignatureFactory`) by removing the `isMorphRelation` parameter and always using the morph relation path - Remove feature flag checks from 7 frontend hooks/components that were gating attachment and activity target behavior behind the removed flags - Simplify `buildDefaultRelationFlatFieldMetadatasForCustomObject` server util to always treat attachment, noteTarget, and taskTarget as morph relations without checking feature flags

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
