If-else branches cannot be recreated once deleted. Only else-if branches
can. On if-else branches removal, we now remplace the node by an empty
node instead of only deleting
Also fixing nested if-else.
## Summary
- **Model pricing overhaul**: All model constants updated with accurate
pricing in dollars per 1M tokens, including cached input rates, cache
creation rates, and tiered >200k context pricing
- **New providers**: Added Google (Gemini 3.x), Mistral, and AWS Bedrock
as inference providers. Bedrock serves Claude Opus 4.6 and Sonnet 4.6
via AWS, with proper credential handling following the existing S3/SES
pattern
- **InferenceProvider/ModelFamily split**: Refactored `ModelProvider`
into two orthogonal enums — `InferenceProvider` (who serves the model:
auth, SDK, metadata format) and `ModelFamily` (who created it: token
counting semantics). This eliminates growing `||` chains for token
normalization checks like `excludesCachedTokens`
- **Billing improvements**: Reasoning tokens charged at output rate,
cache token discounts applied accurately, real errors thrown to Sentry
on billing failures
## Test plan
- [x] All existing unit tests updated and passing (23 tests across 3
test files)
- [x] Lint passes for both twenty-server and twenty-front
- [ ] CI checks pass

## Summary
- **Consolidate logic function services**: Remove
`LogicFunctionMetadataService` and consolidate all logic function CRUD
operations into `LogicFunctionFromSourceService`, with a new
`LogicFunctionFromSourceHelperService` for shared validation/migration
logic
- **Introduce typed conversion utils following the skill pattern**: Add
`fromCreateLogicFunctionFromSourceInputToUniversalFlatLogicFunctionToCreate`
and `fromUpdateLogicFunctionFromSourceInputToFlatLogicFunctionToUpdate`
that convert DTO inputs directly to flat entities
(`UniversalFlatLogicFunction` / `FlatLogicFunction`), replacing the
previous intermediate `UpdateLogicFunctionMetadataParams` indirection
- **Simplify `CodeStepBuildService`**: Remove ~100 lines of manual
duplication logic by delegating to
`LogicFunctionFromSourceService.duplicateOneWithSource`
- **Remove completed 1-17 migration**: Delete
`MigrateWorkflowCodeStepsCommand` and associated utils that migrated
workflow code steps from serverless functions to logic functions
# Introduction
## Centralize system field definitions
- Extract a single `PARTIAL_SYSTEM_FLAT_FIELD_METADATAS` constant as the
source of truth for all 8 system fields (`id`, `createdAt`, `updatedAt`,
`deletedAt`, `createdBy`, `updatedBy`, `position`, `searchVector`),
eliminating duplication across custom object and standard app field
builders
- Refactor `buildDefaultFlatFieldMetadatasForCustomObject` to use the
shared constant via a new `buildObjectSystemFlatFieldMetadatas` helper
## Mark system fields as `isSystem: true`
- Fields `id`, `createdAt`, `updatedAt`, `deletedAt`, `createdBy`,
`updatedBy`, `position`, `searchVector` are now properly flagged as
system fields across all standard objects and custom object creation
- Standard app field builders for all ~30 standard objects updated to
set `isSystem: true` on `createdAt`, `updatedAt`, `deletedAt`,
`createdBy`, `updatedBy`
- System-only standard objects (blocklist, calendar channels, message
threads, etc.) now also include `createdBy`, `updatedBy`, `position`,
`searchVector` field definitions that were previously missing
## Validate system fields on object creation
- New transversal validation (`crossEntityTransversalValidation`) runs
after all atomic entity validations in the build orchestrator, ensuring
all 8 system fields are present with correct `type` and `isSystem: true`
when an object is created
- New `buildUniversalFlatObjectFieldByNameAndJoinColumnMaps` utility to
resolve field names to universal identifiers for a given object
- New exception codes: `MISSING_SYSTEM_FIELD` and `INVALID_SYSTEM_FIELD`
on `ObjectMetadataExceptionCode`
## Protect system fields and objects from mutation
- Field validators now block update/delete of `isSystem` fields by
non-system callers (`FIELD_MUTATION_NOT_ALLOWED`)
- Object validators now block update/delete of `isSystem` objects by
non-system callers
- `POSITION` and `TS_VECTOR` field type validators replaced: instead of
rejecting creation outright, they now validate that the field is named
correctly (`position` / `searchVector`) and has `isSystem: true`
## Distinguish `isSystemBuild` from `isCallerTwentyStandardApp`
- New `isCallerTwentyStandardApp` utility checks whether the caller's
`applicationUniversalIdentifier` matches the twenty standard app
- Name-sync logic (`isFlatFieldMetadataNameSyncedWithLabel`,
`areFlatObjectMetadataNamesSyncedWithLabels`) refactored to use
`isCallerTwentyStandardApp` for custom suffix decisions, keeping
`isSystemBuild` for mutation permission checks
- `WorkspaceMigrationBuilderOptions` type updated to include
`applicationUniversalIdentifier`
## Adapt frontend filtering
- New `HIDDEN_SYSTEM_FIELD_NAMES` constant (`id`, `position`,
`searchVector`) and `isHiddenSystemField` utility to only hide truly
internal fields while keeping user-facing system fields (`createdAt`,
`updatedAt`, `deletedAt`, `createdBy`, `updatedBy`) visible in the UI
- ~20 frontend files updated to replace `!field.isSystem` checks with
`!isHiddenSystemField(field)` across record index, settings, data model,
charts, workflows, spreadsheet import, aggregations, and role
permissions
## Add 1.19 upgrade commands
- **`backfill-system-fields-is-system`**: Raw SQL command to set
`isSystem = true` on existing workspace fields matching system field
names, and fix `position` field type from `NUMBER` to `POSITION` for
`favorite`/`favoriteFolder` objects. Includes proper cache invalidation.
- **`add-missing-system-fields-to-standard-objects`**: Codegen'd
workspace migration to create missing `position`, `searchVector`,
`createdBy`, `updatedBy` fields on standard objects that didn't
previously have them. Runs via `WorkspaceMigrationRunnerService` in a
single transaction with idempotency check. **Known limitation**: assumes
all standard objects exist and are valid in the target workspace.
## Add `universalIdentifier` for system fields in standard object
constants
- `standard-object.constant.ts` updated to include `universalIdentifier`
for `createdBy`, `updatedBy`, `position`, and `searchVector` across all
standard objects
- `fieldManifestType.ts` updated to support the new field manifest shape
## System relation
Completely removed and backfilled all `isSystem` relation to be false
false
As we won't require an object to have any relation system fields
## Add integration tests
- New test suite `failing-sync-application-object-system-fields`
covering: missing system fields, wrong field types (`id` as TEXT,
`createdAt` as TEXT, `position` as TEXT), system field deletion
attempts, and system field update attempts
- New test utilities: `buildDefaultObjectManifest` (builds an object
manifest with all 8 system fields) and `setupApplicationForSync`
(centralizes application setup)
- Existing successful sync test updated to verify system fields are
created with correct properties
## Next step
Make the builder scope the compared entity to be the currently built app
+ nor twenty standard app
This PR adds Message folder association for message channel messages,
Currently under testing phase, not ready yet.

## Refactor page layout widget types into shared package and expose from
SDK
### Why
Widget configuration types were defined only on the server, forcing SDK
consumer apps to import from deep internal `twenty-shared/dist` paths —
fragile and breaks on structural changes. Server DTOs also had no
compile-time guarantee they matched the canonical types.
### What changed
- **`twenty-shared`**: Migrated `ChartFilter`, `GridPosition`,
`RatioAggregateConfig` and all 20 widget configuration variants into
`twenty-shared/types`. `PageLayoutWidgetConfiguration` (base, with
`SerializedRelation`) and `PageLayoutWidgetUniversalConfiguration`
(derived via `FormatRecordSerializedRelationProperties`) are now the
single source of truth.
- **`twenty-sdk`**: Re-exported `AggregateOperations`,
`ObjectRecordGroupByDateGranularity`, `PageLayoutTabLayoutMode`, and
`PageLayoutWidgetUniversalConfiguration` so consumer apps import from
`twenty-sdk` directly.
- **`twenty-server`**: All widget DTOs now `implements` their shared
type for compile-time enforcement. Added helpers to convert nested
`fieldMetadataId` ↔ `fieldMetadataUniversalIdentifier` inside chart
filters. Removed redundant local type re-exports.
## Summary
- Replace all generic `"Unknown error"` fallback messages across the
server codebase with messages that include the actual error details
- The most impactful change is in `guard-redirect.service.ts`, which
handles OAuth redirect errors — non-`AuthException` errors (e.g.,
passport state verification failures) now show `"Authentication error:
<actual message>"` instead of the opaque `"Unknown error"`
- Gmail/Google error handler services now include the error message in
the thrown exception instead of discarding it
- Other catch blocks (workflow delay resume, migration runner rollback,
code interpreter, marketplace) now use `String(error)` for non-Error
objects instead of a static fallback
Fixes the class of issues reported in
https://github.com/twentyhq/twenty/issues/17812, where a user saw
"Unknown error" during Google OAuth and had no way to diagnose the root
cause (which turned out to be a session cookie / SSL configuration
issue).
## Test plan
- [ ] Verify OAuth error flows (e.g., Google Auth with misconfigured
callback URL) now display the actual error message on the `/verify` page
instead of "Unknown error"
- [ ] Verify Gmail sync error handling still correctly classifies and
re-throws errors with descriptive messages
- [ ] Verify workflow delay resume failures include the error details in
the workflow run status

This fixes two edge cases for Gmail
- When policy was set to `SELECTED_FOLDERS` excluding root INBOX, it
missed label changes, so messages with newly applied labels weren't
imported until a full resync.
- Gmail thread replies by default by default do no inherit parent
message's label properties so thread context was also lost because only
individually labeled messages were returned, dropping earlier parts of
the conversation.
Fixed by subscribing to `labelAdded`/`labelRemoved` history events and
fetching full thread context when at least one message in a thread
carries a synced label. `ALL_FOLDERS` path is untouched.
- Create a common file-by-id download controller
- Create core picture module with resolver and logic to handle
workspaceLogo and workspaceMemberProfilePicture update
- Create workflow file module (same)
- Data migration
Gmail 429/403 rate-limit responses include an explicit retry-after
timestamp, usually ~15 minutes out.
The exponential backoff starts at 1 minute, so the channel burns through
all 5 retry attempts before the window actually closes and gets marked
as permanently failed.
Adds throttleRetryAfter to the message channel and uses max(backoff,
retryAfter) in isThrottled().
## Summary
- **Fix token renewal endpoint**: Use `/metadata` instead of `/graphql`
for token renewal in agent chat, fixing auth issues
- **Improve tool display**: Add `load_skills` support, show formatted
tool names (underscores → spaces) with finish/loading states, display
tool icons during loading, and support custom loading messages from tool
input
- **Refactor workflow agent management**: Replace direct
`AgentRepository` access with `AgentService` for create/delete/find
operations in workflow steps, improving encapsulation and consistency
- **Simplify Apollo client usage**: Remove explicit Apollo client
override in `useGetToolIndex`, add `AgentChatProvider` to
`AppRouterProviders`
- **Fix load-skill tool**: Change parameter type from `string` to `json`
for proper schema parsing
- **Update agent-chat-streaming**: Use `AgentService` for agent
resolution and tool registration instead of direct repository queries
## Test plan
- [ ] Verify AI agent chat works end-to-end (send message, receive
response)
- [ ] Verify tool steps display correctly with icons and proper messages
during loading and after completion
- [ ] Verify workflow AI agent step creation and deletion works
correctly
- [ ] Verify workflow version cloning preserves agent configuration
- [ ] Verify token renewal works when tokens expire during agent chat

## Fix resolver schema leaking between `/metadata` and `/graphql`
endpoints
### Summary
- Patch `@nestjs/graphql` to support a `resolverSchemaScope` option that
filters resolvers at both schema generation and runtime, preventing
cross-endpoint leaking
- Introduce `@CoreResolver()` and `@MetadataResolver()` decorators to
explicitly scope each resolver to its endpoint
- Move most resolvers (auth, billing, workspace, user, etc.) to the
metadata schema where the frontend expects them; only workflow and
timeline calendar/messaging resolvers remain on `/graphql`
- Fix frontend `SSEQuerySubscribeEffect` to use the default (metadata)
Apollo client instead of the core client
### Problem
NestJS GraphQL's module-based resolver discovery traverses transitive
imports, causing resolvers from `/metadata` modules to leak into the
`/graphql` schema and vice versa. This made the schemas unpredictable
and tightly coupled to module import order.
### Approach
- Added `resolverSchemaScope` to `GqlModuleOptions` via a patch on
`@nestjs/graphql`, filtering in both `filterResolvers()` (runtime
binding) and `getAllCtors()` (schema generation)
- Each resolver is explicitly decorated with `@CoreResolver()` or
`@MetadataResolver()`
- Organized decorator, constant, and type files under `graphql-config/`
following project conventions
Core GQL Schema: (see: no more fields!)

## Summary
- **Extract `SecureHttpClientService`** from `tool` module into a
dedicated `core-modules/secure-http-client/` module with proper NestJS
module encapsulation
- **Fix module hygiene**: 12 modules that incorrectly listed
`SecureHttpClientService` as a direct provider now properly import
`SecureHttpClientModule`
- **Add structured logging** for outbound HTTP requests with
workspace/user context (for GuardDuty alert correlation)
- **Rename type files** to follow one-export-per-file convention
(`get-secure-axios-adapter.types.ts` ->
`secure-adapter-dependencies.type.ts`, new
`outbound-request-context.type.ts` / `outbound-request-source.type.ts`)
### Why
`SecureHttpClientService` is a cross-cutting concern (used by auth,
captcha, file upload, geo-map, telemetry, admin-panel, REST API, contact
creation, webhooks, and workflow tools) but was bundled inside the
`tool` module. Most consumers worked around this by listing it as a
direct provider instead of importing a module, which is fragile and not
idiomatic NestJS.
## Test plan
- [x] All 60 unit tests pass (`secure-http-client.service.spec.ts`,
`get-secure-axios-adapter.util.spec.ts`, `is-private-ip.util.spec.ts`)
- [x] Related module tests pass (admin-panel, contact-creation, tool)
- [x] `npx nx typecheck twenty-server` passes
- [x] `npx nx lint:diff-with-main twenty-server` passes
- [x] Server compiles and bootstraps successfully

## Changes
### System prompt improvements
- Explicit skill-before-tools workflow to prevent the model from calling
tools without loading the matching skill first
- Data efficiency guidance (default small limits, use filters)
- Pluralized `load_skill` → `load_skills` for consistency with
`load_tools`
### Token usage reduction
- Output serialization layer: strips null/undefined/empty values from
tool results
- Lowered default `find_*` limit from 100 → 10, max from 1000 → 100
### System object tool generation
- System objects (calendar events, messages, etc.) now generate AI tools
- Only workflow-related and favorite-related objects are excluded
### Context window display fix
- **Bug**: UI compared cumulative tokens (sum of all turns) against
single-request context window → showed 100% after a few turns
- **Fix**: Track `conversationSize` (last step's `inputTokens`) which
represents the actual conversation history size sent to the model
- New `conversationSize` column on thread entity with migration
### Workspace AI instructions
- Support for custom workspace-level AI instructions

# Introduction
Requiring the spreaded `__universal` record that aggregates all the
universal identifier ( relations fk and aggregators ) of an entity to
its root
It's blockin for https://github.com/twentyhq/twenty/pull/17687 to be
finalized because if we don't we would have to migrated all related
entities at once in order for them to always have the universal
properties
## `resolveEntityRelationUniversalIdentifiers`
Introduced `resolveEntityRelationUniversalIdentifiers` a centralized
utility that resolves foreign key IDs to universal identifiers using
ALL_METADATA_RELATIONS metadata. It provides strict typing for both
input (foreign keys) and output (universal identifiers), with
nullability dynamically inferred from entity relation types.
Strictly and dynamically typed for both output and input
To do so added a new type and const/runtime grain to
ALL_METADATA_RELATIONS `isNullable`to many-to-one entries, derived from
the entity relation property types. And fixed incorrectly typed typeorm
entities
### Usage
```ts
const {
availabilityObjectMetadataUniversalIdentifier,
frontComponentUniversalIdentifier,
} = resolveEntityRelationUniversalIdentifiers({
metadataName: 'commandMenuItem',
foreignKeyValues: {
availabilityObjectMetadataId:
createCommandMenuItemInput.availabilityObjectMetadataId,
frontComponentId: createCommandMenuItemInput.frontComponentId,
},
flatEntityMaps: { flatObjectMetadataMaps, flatFrontComponentMaps },
});
```
- Add FILES field on attachment
- Adapt Attachment logic in front to use new resolver/controller
- Update files-field logic to infer applicationId from fieldMetadataId +
ask for fieldMetadataId in upload resolver
- Design update
To do in next PR :
- Adapt activity files logic
Issue 1: no info to debug cron trigger. Stop catching exception + using
logs instead of throwing for now
Issue 2: sentry often send timeouts errors for workflow crons. Probably
not real ones, it sends it if the job takes more than 5 minutes to run.
To fix, on each workflow cron we do:
- loop over active workspaces
- perform a query check that workspace is relevant, using count for
performances
- send a job if relevant
# Refactor workflow–logic function interaction
## Why
Workflow code steps and standalone logic functions shared the same build
layer and DB layer, which blurred two use cases: code steps belong to a
workflow version; standalone functions are deployable units. That made
workflow code steps harder to own and evolve.
## Goal
Treat code steps as **workflow-owned**: build and run them in workflow
context, and expose workflow-scoped APIs so the editor can load, test,
and save code step source without going through the generic
logic-function layer.
Previous code in `MESSAGING_GMAIL_DEFAULT_NOT_SYNCED_LABELS` was
problematic as we grouped `category` labels along with `system folders`
labels together.
This fixes partially missing emails issue by splitting it and not
applying category exclusion when querying for a singular custom label.
Also removes old approach of getting message label_id's association from
additional network call overhead to local utility
`filterGmailMessagesByFolderPolicy`
## Remove logic function layer
Package.json and yarn.lock are now on the application entity, so the
logic function layer is no longer used except as a legacy source for the
1.17 backfill. This PR removes all layer usage outside of that migration
and keeps only the entity for backfill.
### Summary
- **Kept:** `LogicFunctionLayerEntity` and its table, only used by the
1.17 backfill command to read legacy layer data and backfill application
package files.
- **Removed:** All other layer logic: CRUD, cache, resolvers, services,
DTOs, and frontend types. Logic functions now depend only on the
application for package/dependency context.
### Why Dependencies instead of Source for package files
Package.json and yarn.lock are the application’s dependency set and are
stored under the application in **FileFolder.Dependencies**. The build
service and drivers now read them only from Dependencies; nothing is
written to Source for these files.
This PR migrates `noteTarget` and `taskTarget` to morph relations behind
separate feature flags, following the Attachment/TimelineActivity
pattern.
It introduces the `IS_NOTE_TARGET_MIGRATED` and
`IS_TASK_TARGET_MIGRATED` flags, updates standard field metadata and
indexes to use morph relations, and adds two **1.17 workspace
migrations** that:
- rename `noteTarget.*Id` / `taskTarget.*Id` columns to `target*Id`
- convert the corresponding field metadata to `MORPH_RELATION` with a
shared `morphId`
On the frontend, note/task target read and write paths switch to
`target*Id` when the respective flag is enabled. Deleted targets are
filtered on reload to prevent reappearing relations.
Replace manual HTTP batch implementation with
`@jrmdayn/googleapis-batcher` library (we already use this for fetching
message list)
Initial real testing works fine but do not merge yet needs more
extensive real test runs
PR #17492 fixed `markAsMessagesListFetchOngoing` to set
`syncStageStartedAt`, but also changed `isSyncStale` to return `false`
for null values. This prevented the stale recovery job from recovering
channels that were already stuck before the fix was deployed.
Changing `isSyncStale` to return `true` for null/undefined allows the
stale job to properly reset stuck channels back to PENDING state.
# Introduction
In preparation of the workspace agnostic builder, we're migrating
`FlatEntityMaps` to be universal identifier oriented and based
As in the builder context there're won't be any ids at all
Please also note that the FlatEntity is a UniversalFlatEntity superset
From
```ts
import { type SyncableFlatEntity } from 'src/engine/metadata-modules/flat-entity/types/flat-entity-from.type';
export type FlatEntityMaps<T extends SyncableFlatEntity> = {
byId: Partial<Record<string, T>>;
idByUniversalIdentifier: Partial<Record<string, string>>;
universalIdentifiersByApplicationId: Partial<Record<string, string[]>>;
};
```
To
```ts
export type FlatEntityMaps<
T extends SyncableFlatEntity | UniversalSyncableFlatEntity,
> = {
byUniversalIdentifier: Partial<Record<string, T>>;
universalIdentifierById: Partial<Record<string, string>>;
universalIdentifiersByApplicationId: Partial<Record<string, string[]>>; // this might make more sense to be migrated to universalIdentifiersByApplicationUniversalIdentifier but it's the main topic of this PR
};
```
## Low level maps tools
Had to refactor find | create | delete | replace | find-many | get-sub
tools ( through mutations and or throw equivalent )
# Introduction
Following https://github.com/twentyhq/twenty/pull/17632 and
https://github.com/twentyhq/twenty/pull/17572
This PR deprecates the agent, skill, field metadata and role
`standardId` in favor of the `universalIdentifier` usage
## Note
- Removed previous standard ids declaration modules
- Twenty-sdk now re-exports the `STANDARD_OBJECTS` universalIdentifier
hashmap constant
- deleted some sync-metadata deadcode too ( mainly types )
# Introduction
In this PR we're deprecating the object metadata standard id and
replacing it to the universalIdentifier usage
As we've totally removed its insertion for both new field and object in
https://github.com/twentyhq/twenty/pull/17572
## Note
- Removed upgrade commands before `1.17`
# Introduction
Important note: This PR officially deprecates the `standardId`, about to
drop col and entity property after this has been merged
Important note2: Haven't updated the optimistic tool to also update the
universal identifier aggregators only the ids one, they should not be
consumed in the runner context -> need to improve typing or either the
optimistic tooling
In this PR we're introducing all the devxp allowing future metadata
incremental universal migration -> this has an impact on all existing
metadata actions handler ( explaining its size )
This PR also introduce workspace agnostic create update actions runner
for both field and object metadata in order to battle test the described
above devxp
Noting that these two metadata are the most complex to handle
Notes:
- A workspace migration is now highly bind to a
`applicationUniversalIdentifier`. Though we don't strictly validate
application scope for the moment
## Next
Migrate both object and field builder to universal comparison
## Universal Actions vs Flat Actions Architecture
### Concept
The migration system uses a two-phase action model:
1. **Universal Actions** - Actions defined using `universalIdentifier`
(stable, portable identifiers like `standardId` + `applicationId`)
2. **Flat Actions** - Actions defined using database `entityId` (UUIDs
specific to a workspace)
### Why This Separation?
- **Universal actions are portable**: They can be serialized, stored,
and replayed across different workspaces
- **Flat actions are executable**: They contain the actual database IDs
needed to perform operations
- **Decoupling**: The builder produces universal actions; the runner
transpiles them to flat actions at execution time
### Transpiler Pattern
Each action handler must implement
`transpileUniversalActionToFlatAction()`:
```typescript
@Injectable()
export class CreateFieldActionHandlerService extends WorkspaceMigrationRunnerActionHandler(
'create',
'fieldMetadata',
) {
override async transpileUniversalActionToFlatAction(
context: WorkspaceMigrationActionRunnerArgs<UniversalCreateFieldAction>,
): Promise<FlatCreateFieldAction> {
// Resolve universal identifiers to database IDs
const flatObjectMetadata = findFlatEntityByUniversalIdentifierOrThrow({
flatEntityMaps: allFlatEntityMaps.flatObjectMetadataMaps,
universalIdentifier: action.objectMetadataUniversalIdentifier,
});
return {
type: action.type,
metadataName: action.metadataName,
objectMetadataId: flatObjectMetadata.id, // Resolved ID
flatFieldMetadatas: /* ... transpiled entities ... */,
};
}
}
```
### Action Handler Base Class
`BaseWorkspaceMigrationRunnerActionHandlerService<TActionType,
TMetadataName>` provides:
- **`transpileUniversalActionToFlatAction()`** - Abstract method each
handler must implement
- **`transpileUniversalDeleteActionToFlatDeleteAction()`** - Shared
helper for delete actions
## FlatEntityMaps custom properties
Introduced a `TWithCustomMapsProperties` generic parameter to control
whether custom indexing structures are included:
- **`false` (default)**: Returns `FlatEntityMaps<MetadataFlatEntity<T>>`
- used in builder/runner contexts
- **`true`**: Returns the full maps type with custom properties (e.g.,
`byUserWorkspaceIdAndFolderId`) - used in cache contexts
## Create Field Actions Refactor
Refactored create-field actions to support relation field pairs
bundling.
**Problem:** Relation fields (e.g., `Attachment.targetTask` ↔
`Task.attachments`) couldn't resolve each other's IDs during
transpilation because they were in separate actions with independent
`fieldIdByUniversalIdentifier` maps.
**Solution:**
- Removed `objectMetadataUniversalIdentifier` from
`UniversalCreateFieldAction` and `objectMetadataId` from
`FlatCreateFieldAction` - each field now carries its own
- Runner groups fields by object internally and processes each table
separately
- Split aggregator into two focused utilities:
- `aggregateNonRelationFieldsIntoObjectActions` - merges non-relation
fields into object actions
- `aggregateRelationFieldPairs` - bundles relation pairs with shared
`fieldIdByUniversalIdentifier`
