isCustom deprecation for Objects and Fields (#21228)

## Context `isCustom` was a legacy denormalized boolean on `ObjectMetadataEntity` and `FieldMetadataEntity`. Now that every metadata row carries `applicationId` (via `SyncableEntity`), "is this custom" is fully derivable, and the stored boolean was a redundant second source of truth that could drift. The real meaning of `isCustom` is **"the owning application is not the twenty-standard application"** — i.e. `!belongsToTwentyStandardApp`. Note this is *not* "belongs to the workspace custom app" as I initially thought: third-party-application objects/fields are custom too. The standard application has a globally stable `universalIdentifier`, so the value derives with no per-workspace lookup. ## Changed ## `isCustom` checks — before → after `isCustom` is no longer a stored column. The table below lists every site that branched on it and how it resolves now. The unifying rule: `isCustom ≡ !isTwentyStandardApplicationUniversalIdentifier(applicationUniversalIdentifier)`. ### Server — behavioural checks | Location | Purpose | Before | Now | |---|---|---|---| | `utils/compute-object-target-table.util.ts` | Physical table name `_` prefix | `computeTableName(nameSingular, objectMetadata.isCustom)` | derives from `applicationUniversalIdentifier` (single source for all table-name callers) | | `twenty-orm/factories/entity-schema.factory.ts` + `…/entity-schema-metadata.type.ts` | ORM table name (hot path) | `object.isCustom` | `object.applicationId !== standardApplicationId` (computed in `buildEntitySchemaMetadataMaps`) | | `twenty-orm/repository/workspace-{delete,soft-delete,update}-query-builder.ts` | Table name for mutations | `computeTableName(nameSingular, objectMetadata.isCustom)` | `computeObjectTargetTable(objectMetadata)` | | `index-metadata/utils/generate-deterministic-index-name-v2.ts` | Index name hash (must stay bit-identical) | `flatObjectMetadata.isCustom` | derives from `applicationUniversalIdentifier` | | `object-metadata/object-record-count.service.ts` | Table name for record count | `computeTableName(nameSingular, isCustom)` | `computeObjectTargetTable(flatObjectMetadata)` | | `workspace-manager/dev-seeder/data/services/dev-seeder-data.service.ts` | Match seed config by table name | `computeTableName(item.nameSingular, item.isCustom)` | `computeObjectTargetTable(item)` | | `commands/workspace-export/workspace-export.service.ts` + `…/utils/generate-workspace-schema-ddl.util.ts` | Export table name (raw entity) | `objectMetadata.isCustom` | `!isTwentyStandard…(objectMetadata.application?.universalIdentifier)` | | `flat-field-metadata/services/flat-field-metadata-type-validator.service.ts` | Block users creating reserved field types | `args.flatEntityToValidate.isCustom` | `!args.flatEntityToValidate.isSystem` | | `api/common/.../common-create-many-query-runner.service.ts` | Don't let client overwrite system `createdBy` | `createdByFieldMetadata.isCustom === false` | `createdByFieldMetadata.isSystem === true` | | `field-metadata/utils/resolve-field-metadata-standard-override.util.ts` | Skip i18n/overrides for custom fields | `if (fieldMetadata.isCustom) return raw` | **removed** — falls through on `isDefined(standardOverrides)` | | `object-metadata/utils/resolve-object-metadata-standard-override.util.ts` | Skip i18n/overrides for custom objects | `if (objectMetadata.isCustom) return raw` | **removed** — same fall-through | | `command-menu-item/utils/build-navigation-interpolation-context.util.ts` | Override context for nav labels | passed `isCustom` into resolver | dropped (resolver no longer needs it) | | `api/common/.../data-arg-processor.service.ts` | `isCustom` for record-position table name | `flatObjectMetadata.isCustom` | derives from `applicationUniversalIdentifier` | | `metadata-modules/minimal-metadata/minimal-metadata.service.ts` | Minimal DTO + override context | `flatObjectMetadata.isCustom` | derives from `applicationUniversalIdentifier` | | `commands/upgrade-version-command/1-23/…backfill-record-page-layouts.command.ts` | Filter to custom objects | `objectMetadata.isCustom` | `!isTwentyStandard…(applicationUniversalIdentifier)` | ### Server — DTO / API population | Location | Before | Now | |---|---|---| | `flat-object-metadata/utils/from-flat-object-metadata-to-object-metadata-dto.util.ts` | passthrough `isCustom` | derives from `applicationUniversalIdentifier` | | `flat-field-metadata/utils/from-flat-field-metadata-to-field-metadata-dto.util.ts` | passthrough `isCustom` | derives from `applicationUniversalIdentifier` | | `object-metadata/utils/from-object-metadata-entity-to-object-metadata-dto.util.ts` (REST) | `entity.isCustom` | `entity.applicationId !== standardApplicationId` | | `field-metadata/utils/from-field-metadata-entity-to-field-metadata-dto.util.ts` (REST) | `entity.isCustom` | `entity.applicationId !== standardApplicationId` | | `dataloaders/dataloader.service.ts` | passed `flatFieldMetadata.isCustom` into override resolver | dropped (resolver no longer needs it) | > REST controllers (`object-metadata.controller.ts`, `field-metadata.controller.ts`) resolve `standardApplicationId` once per request from the cached `flatApplicationMaps`. ### Frontend | Location | Purpose | Before | Now | |---|---|---|---| | `settings/.../SettingsObjectFieldDisabledActionDropdown.tsx` | Whether an inactive field is deletable | `isDeletable = isCustomField` | `isDeletable = isCustomField && !isSystemField` | ### Unchanged (out of scope) `isCustom` on `IndexMetadata` / `View` / `Skill` / `Agent` and their guards still read the persisted column. Breaking change is on the isCustom filter on field and object APIs, this is never used in the FE and unlikely used by external consumers
