## Summary
- Add `WORKSPACE_SCHEMA_DDL_LOCKED` env-only boolean config variable
that blocks all workspace schema DDL changes when set to `true`. This is
intended for hot upgrades where logical replication cannot handle DDL
changes. Enforced at two chokepoints:
- `WorkspaceMigrationRunnerService.run` — blocks all metadata-driven DDL
(object/field/index CRUD, app sync/uninstall, standard app sync, upgrade
commands)
- `WorkspaceDataSourceService.createWorkspaceDBSchema` /
`deleteWorkspaceDBSchema` — blocks workspace creation (sign-up) and hard
deletion. Uses a dedicated `WorkspaceDataSourceException` (not
ForbiddenException)
- Add maintenance mode feature with Admin Panel UI and user-facing
banner:
- **Backend**: `MaintenanceModeService` stores maintenance window
(startAt, endAt, optional link) in `core.keyValuePair` as
`CONFIG_VARIABLE`. Validates endAt > startAt. Uses `GraphQLISODateTime`
scalar for date fields. Exposed via `clientConfig` REST endpoint and
admin GraphQL mutations (`setMaintenanceMode`, `clearMaintenanceMode`)
- **Admin Panel**: New "Maintenance Mode" section in Health tab with UTC
datetime pickers and activate/deactivate controls
- **Banner**: `InformationBannerMaintenance` displayed at the top of
`DefaultLayout` for all users, using Temporal API for timezone-aware
formatting with an optional "Learn more" link
These two features are **independent** — the DDL lock is controlled via
env var for operational use, while maintenance mode is a UI notification
mechanism controlled from the admin panel.
- Deduplicate standard record command menu items by merging
single-record and multi-record delete, restore, destroy, and export
actions into shared record commands.
- Update frontend command registrations and engine component mappings to
use the new unified keys, while keeping deprecated engine keys
temporarily mapped for backward compatibility.
- Add a 1-21 upgrade command that removes legacy command menu items from
workspaces and creates the new unified standard items.
- `frontComponentHostCommunicationApi` gets a new object reference on
every render, causing the `useMemo`/`useEffect` in
`FrontComponentWorkerEffect` to tear down and re-create the web worker
each time.
- Decouple the host API lifecycle from the worker lifecycle by moving
thread.exports updates into a dedicated
`FrontComponentUpdateHostCommunicationApiEffect` that mutates the
thread's exports object in place via Object.assign.
- Rename `FrontComponentHostCommunicationApiEffect` to
`FrontComponentInitializeHostCommunicationApiEffect` for clarity.

## Summary
- **Queue messages while streaming**: Messages sent during active AI
streaming are queued server-side and auto-flushed when the current
stream completes. Frontend renders queued messages optimistically in a
dedicated queue UI.
- **Drop `@ai-sdk/react` + `resumable-stream`**: Replace the dual HTTP
SSE + AI SDK client architecture with a single GraphQL SSE subscription
per thread. All events (token chunks, message persistence, queue
updates, errors) flow through Redis PubSub → GraphQL subscription.
- **Server-driven architecture**: The server decides whether to queue or
stream (via `POST /:threadId/message`). The frontend mirrors this
decision for optimistic rendering but defers to the server response.
- **Reuse AI SDK accumulation logic**: `readUIMessageStream` from the
`ai` package handles chunk-to-message accumulation on the frontend,
avoiding a custom 780-line accumulator.
## Key files
**Backend:**
- `agent-chat-event-publisher.service.ts` — publishes events to Redis
PubSub
- `agent-chat-subscription.resolver.ts` — GraphQL subscription resolver
- `stream-agent-chat.job.ts` — publishes chunks via PubSub instead of
resumable-stream
- `agent-chat.controller.ts` — unified `POST /:threadId/message`
endpoint
**Frontend:**
- `useAgentChatSubscription.ts` — subscribes to `onAgentChatEvent`,
bridges to `readUIMessageStream`
- `useAgentChat.ts` — send/stop/optimistic rendering (no more AI SDK)
- `AgentChatStreamSubscriptionEffect.tsx` — replaces
`AgentChatAiSdkStreamEffect.tsx`
## Test plan
- [ ] Send message on new thread → optimistic render, streaming response
appears
- [ ] Send message while streaming → queued instantly (no flash in main
thread)
- [ ] Queued message auto-flushes after current stream completes
- [ ] Remove queued message via queue UI
- [ ] Stop streaming mid-response
- [ ] Leave chat idle for several minutes → streaming still works after
(SSE client recycling)
- [ ] Token refresh during session → requests succeed (authenticated
fetch)
- [ ] Switch threads while streaming → clean subscription handoff

Add a new "Manage" section in FIELDS widget side panel with a "Delete
widget" action
Next step: Deleting a non-custom fields widget should be reversible

- Adds a resolveObjectMetadataLabel utility that returns the singular or
plural label from object metadata based on the number of selected
records (e.g., "person" vs "people").
- Exposes a pre-computed objectMetadataLabel string on
CommandMenuContextApi, making it available for label interpolation
(e.g., Delete ${capitalize(objectMetadataLabel)}).

📄 Summary
This PR upgrades the nodemailer dependency to a secure version (≥ 8.0.4)
to fix a known SMTP command injection vulnerability
(GHSA-c7w3-x93f-qmm8).
🚨 Issue
The current version used in twenty-server (^7.0.11, resolved to 7.0.11 /
7.0.13) is vulnerable to SMTP command injection due to improper
sanitization of the envelope.size parameter.
This could allow CRLF injection, potentially enabling attackers to add
unauthorized recipients to outgoing emails.
🔍 Root Cause
The vulnerability originates from insufficient validation of
user-controlled input in the SMTP envelope, specifically the size field,
which can be exploited via crafted input containing CRLF sequences.
✅ Changes
Upgraded nodemailer to version ^8.0.4
Ensured compatibility with existing email sending logic
Verified that no breaking changes affect current usage
🔐 Security Impact
This update mitigates the risk of:
SMTP command injection
Unauthorized email recipient manipulation
Potential data leakage via crafted email payloads

## Summary
- Adds `search` and `searches` to the `RESERVED_METADATA_NAME_KEYWORDS`
list in `twenty-shared`
- Prevents users from creating custom objects named "search", which
collides with the core `search` GraphQL resolver
## Summary
- Adds a new `upgrade:1-21:backfill-datasource-to-workspace` command
that copies `dataSource.schema` into `workspace.databaseSchema` for all
active/suspended workspaces that haven't been migrated yet
- Registers the command in the 1-21 upgrade module and wires it into the
upgrade runner (runs before other 1-21 commands)
- Part of the ongoing deprecation of the `dataSource` table in favor of
storing `databaseSchema` directly on `WorkspaceEntity`
This PR completes the sections we need for the Homepage. Assets, such as
images, are still placeholder, and will be replaced as they become
available. We're still waiting on Lottie and 3d asset files from the
design team.
Database batch events (update / insert / soft-delete / hard-delete) were
building recordsBefore / recordsAfter after formatResult ran twice: once
inside WorkspaceSelectQueryBuilder.getMany() / getOne(), and again in
the CUD query builders. On the second pass, already-shaped composite
fields (e.g. emails) went through formatFieldMetadataValue and kept the
same object references as the live TypeORM row, so recordsBefore could
change when the entity was updated—breaking workflow triggers and diffs.
