## Rationale
When an SSE record-update event carries a field the tab's metadata cache
doesn't know (someone added a custom field after this tab loaded),
`computeOptimisticRecordFromInput` throws `Should never occur,
encountered unknown fields …`. The catch in
`useTriggerEventStreamCreation` swallows the throw, so the **entire
event is discarded** — the tab silently stops reflecting that update.
**Production evidence (Sentry):** the `Error while processing SSE
message` family — ~860 events / ~480 users in the last 30 days, ongoing
([TWENTY-FRONT-7PD](https://twenty-v7.sentry.io/issues/TWENTY-FRONT-7PD)
et al.), with the sampled stack landing exactly on this throw. Related:
[TWENTY-FRONT-633](https://twenty-v7.sentry.io/issues/TWENTY-FRONT-633)
(903 users).
## Why this is the root cause, not a symptom patch
The throw is an assertion that unknown fields "should never occur".
That's the correct contract for the 4 local-mutation callers
(`useUpdateOneRecord`, `useCreateOneRecord`, `useCreateManyRecords`,
`useRunWorkflowVersion`) — there, an unknown field is a programming bug.
But for the SSE caller the input comes from the **server**, which can
legitimately be ahead of the tab's metadata. Schema convergence is the
metadata-event pipeline's job (it flows over the same SSE channel); the
record pipeline's job is to tolerate the window. So the fix moves the
decision to the right caller instead of weakening the assertion for
everyone:
- `getUnknownRecordInputFields` — detection logic extracted, shared
- mutation callers: still throw (behavior unchanged)
- SSE update path: filters unknown fields and applies the rest of the
event
Dropping the *fields* loses nothing: the tab couldn't render them anyway
without the metadata, and the metadata event that follows triggers the
proper refresh.
## User impact
~480 users/month currently get silently stale tabs (list/kanban rows not
reflecting teammates' updates) whenever any custom field is added while
they have Twenty open. After this fix, updates keep flowing; only the
not-yet-known field is skipped until metadata converges.
## Test plan
- [x] Unit tests for `getUnknownRecordInputFields` (known fields,
`__typename`, unknown fields, relation join columns)
- [x] Existing `computeOptimisticRecordFromInput` tests cover the
unchanged throw path
- [ ] CI green

## Summary
- Fix intermittent failure where the Quick Lead workflow form step did
not auto-open
- Root cause: race conditions between SSE events, Apollo cache writes,
and the `runWorkflowVersion` mutation timing
- Add generic monotonicity guard in the SSE handler that drops stale
updates for all records (not just WorkflowRun)
## Changes
- **`useTriggerOptimisticEffectFromSseUpdateEvents.ts`**: Compare
incoming `updatedAt` with cached record before writing — skip if stale.
Moved `upsertRecordsInStore` after the guard so neither Apollo cache nor
Jotai store receive stale data.
- **`useRunWorkflowVersion.tsx`**: Await mutation before opening side
panel; register SSE listener eagerly before mutation
- **`useWorkflowRun.ts`**: Simplified back to plain `useFindOneRecord` +
schema parse (no extra state needed)
- **`generateWorkflowRunDiagram.ts`**: `shouldOpenStep` matches both
PENDING and RUNNING for form steps (backend RUNNING means "waiting for
user input")
- **`WorkflowRunVisualizerEffect.tsx`**: Pass `runStatus` directly
without status mapping
- **`WorkflowRunStepNodeDetail.tsx`**: Form is interactive when step is
PENDING or RUNNING
- **Deleted `latestWorkflowRunFamilyState.ts`**: No longer needed — the
generic SSE guard replaces it
## Test plan
- [x] Hard refresh, run Quick Lead workflow 10+ times — form should
always auto-open
- [x] Complete the form and verify all subsequent steps execute without
getting stuck
- [x] Verify the workflow diagram is always visible (never disappears)
- [x] Verify other record types still update correctly via SSE (e.g.
edit a person in another tab)
## Summary
- Renames `ObjectMetadataItem` to `EnrichedObjectMetadataItem` across
the entire frontend (~440 files) to clarify that this type includes
derived fields (`readableFields`, `updatableFields`, nested `fields[]`,
`indexMetadatas[]`) computed at read time from the metadata store
- Creates `splitObjectMetadataGqlResponse` that goes directly from a
GraphQL `ObjectMetadataItemsQuery` response to flat store items
(combining the old
`mapPaginatedObjectMetadataItemsToObjectMetadataItems` +
`splitObjectMetadataItemWithRelated` two-step flow into one call)
- Removes `ObjectMetadataItemWithRelated` type and all "WithRelated"
naming
- Renames `generatedMockObjectMetadataItems` to
`generateTestEnrichedObjectMetadataItemsMock` to make it clear this is
test-only enriched data
- Deletes `useLoadMockedObjectMetadataItems` hook (consolidated into
`useLoadMockedMinimalMetadata`)
- Ensures nothing destined for the metadata store computes
`readableFields`/`updatableFields` (preventing the localStorage bloat
from #18809)
## Type hierarchy (before → after)
**Before:**
```
ObjectMetadataItemsQuery → mapPaginated → ObjectMetadataItemWithRelated → enrich → ObjectMetadataItem
→ split → FlatObjectMetadataItem (store)
```
**After:**
```
ObjectMetadataItemsQuery → splitObjectMetadataGqlResponse → FlatObjectMetadataItem (store)
→ mapPaginated + enrich (tests only) → EnrichedObjectMetadataItem
```
## Test plan
- [x] `npx nx typecheck twenty-front` passes
- [x] `npx nx test twenty-front` passes (767 suites, 4505 tests)
- [x] `npx nx lint twenty-front` passes
- [ ] CI checks pass

## Reduce type leakage between GraphQL schemas
### Why
Twenty runs two separate GraphQL schemas: **core** and **metadata**.
NestJS's `@nestjs/graphql` uses a global `TypeMetadataStorage` that
accumulates all decorated types across all modules. When each schema is
built, every registered type leaks into both schemas regardless of which
module it belongs to.
This means the core schema's generated TypeScript
(`generated/graphql.ts`) contained ~2,700 lines of types that only
belong to the metadata schema (and vice versa). This creates confusion
about type ownership, inflates generated code, and makes it harder to
reason about which API surface each schema actually exposes.
### How
**1. Patch `@nestjs/graphql` to support schema-scoped type resolution**
- **(Already done)** Added a `resolverSchemaScope` option to
`GqlModuleOptions`, allowing each schema to declare a scope (e.g.
`'metadata'`)
- `ResolversExplorerService` now filters resolvers by a
`RESOLVER_SCHEMA_SCOPE` metadata key, so each schema only sees its own
resolvers
- `GraphQLSchemaFactory` now performs a **reachability walk**
(`computeReachableTypes`) starting from scoped resolver return types and
arguments, only including types that are transitively referenced —
handling unions, interfaces, and prototype chains
- Type definition storage and orphaned reference registry are cleared
between schema builds to prevent cross-contamination
**2. Register `ClientConfig` as orphaned type in metadata schema**
Since `ClientConfig` is needed in the metadata schema but not directly
returned by a resolver, it's explicitly declared via
`buildSchemaOptions.orphanedTypes`.
**3. Regenerate frontend types and fix imports**
- `generated/graphql.ts` shrank by ~2,700 lines (types moved to where
they belong)
- `generated-metadata/graphql.ts` gained types like `ClientConfig` that
were previously missing
- ~500 frontend files updated to import from the correct generated file
This PR implements SSE update events across the main components of the
application : tables, boards, calendars, show pages.
There is still work to do on other event type and on making sure
everything works fine, but this first implementation should be robust
enough to start with.
Some problems encountered along the way :
- Events are returning raw Postgres output, because they are not
normalized by the GraphQL layer, so we ended up with amountMicros as
string values, which the frontend does not like, so I implemented a
small util in our `formatResult` generic pipeline to turn amountMicros
to a number if it's a string value. We could implement other formatters
for composite fields if we see problems with events.
-`action` property was missing in SSE events, which is required by the
frontend to know what kind of event it is.
