## Summary
Two intertwined streams of work:
### UI — discovery hero pattern, settings shell, AI/API redesign
- **Generalize `SettingsDiscoveryHeroCard`** and use it on Layout, Data
Model, Apps, AI, API/Webhooks, Members. Drops 4 per-page wrapper files
(`SettingsObjectCoverImage`, `SettingsLayoutCoverImage`,
`SettingsLayoutCustomizeVideoModal`,
`SettingsDataModelVisualizeVideoModal`). Each page now supplies cover
src, modal id, and tab list.
- **Modal**: swap `<video>` placeholder for the Vimeo iframe pattern
from `twenty-docs`, per-tab `vimeoId`. Drop the parallel border-bottom
on the header (TabList draws its own baseline) and the grey background
behind the video. Note: Vimeo's embed allowlist applies — the iframes
load with the correct URL on `localhost` but the player itself requires
the video owner to allow the dev/staging domains in Vimeo settings.
- **AI page** rebuilt into a Cockpit pattern (Overview / Models / Skills
/ Tools / Usage). New `SettingsAiOverviewTab` with default Smart/Fast
pickers, at-a-glance stats, and an MCP signpost that deep-links to
`/settings/api-webhooks#mcp`. System Prompt link moved under Models.
Advanced tab removed.
- **API & Webhooks** now has 4 tabs (Playground / MCP / API Keys /
Webhooks). Hero card above tabs. Playground tab inverted to "Core API" /
"Metadata API" sections, each containing REST + GraphQL cards — schema
is the meaningful axis, protocol is secondary. Hash deep-link sync
delegated to the shared `TabListFromUrlOptionalEffect`.
- **Settings shell**: unified drawer outer padding (kill `isSettings`
branch), extract `CollapsibleNavigationDrawerSection`, add `iconColor`
on settings nav items, fix Exit Settings button alignment, 880px content
cap.
### Backend — strategy C: ephemeral playground token
The legacy paste-your-API-key flow is replaced by an on-demand
short-lived token scoped to the calling user's permissions. No shared
"Playground" API key to manage or revoke.
- New `JwtTokenTypeEnum.PLAYGROUND`. `PlaygroundTokenJwtPayload =
Omit<AccessTokenJwtPayload, 'type' | impersonation fields>` so any
future ACCESS claim flows through automatically.
- `AccessTokenService.generatePlaygroundToken` signs an access-shaped
JWT with `type: PLAYGROUND` and a configurable short TTL. A shared
private `resolveTokenSubject` helper parallelizes the user / workspace /
userWorkspace lookups for both generators.
- `JwtAuthStrategy.validateAccessToken` widened to accept
`AccessTokenJwtPayload | PlaygroundTokenJwtPayload`; impersonation gated
on `payload.type === ACCESS` so the union narrows without `as unknown
as` casts. The two branches in `validate()` collapse into one.
- New `PLAYGROUND_TOKEN_EXPIRES_IN` config var (default `2h`).
- New `generatePlaygroundToken` mutation (`WorkspaceAuthGuard`, no args,
returns `AuthToken`).
- Frontend `useOpenPlayground` hook centralizes mint → atom write →
navigate, with Apollo `onError` snackbar and a "use cached PLAYGROUND
token if still fresh" short-circuit (decodes via `jwt-decode`, checks
both `type` AND `exp`). Old API_KEY tokens left in localStorage from the
prior paste-form flow are rejected on `type` alone and force a re-mint —
this is what was causing the "This API Key is revoked" symptom on stale
browsers.
### Drive-by cleanups
- `PlaygroundToken` DTO removed (identical shape to `AuthToken` already
in use).
- 5 `customize-sidebar.webm` imports and the dead placeholder pipeline
removed.
## Test plan
### Discovery hero
- [ ] `/settings/layout`, `/settings/data-model`,
`/settings/applications`, `/settings/ai`, `/settings/api-webhooks`,
`/settings/members` each render the discovery hero card with its
illustration + play button + tabbed modal
- [ ] Modal tabs show the correct Vimeo embed URL per tab; aspect ratio
stays at 1440/900; no parallel border-bottom jog at the tab baseline
- [ ] AI Overview tab shows Smart/Fast model pickers + stats grid + MCP
signpost card; the MCP card lands on `/settings/api-webhooks#mcp` with
the MCP tab active
### API playground (ephemeral token)
- [ ] With an empty `playgroundApiKeyState` in localStorage, clicking
REST or GraphQL playground card opens the playground and the cached
token has `type: "PLAYGROUND"` with ~2h exp
- [ ] Clicking the card again within the freshness window does **not**
re-mint (`iat` / fingerprint stable across visits)
- [ ] Planting a fake API_KEY-shaped JWT in localStorage and clicking
the card forces a fresh mint (old token rejected on `type`)
- [ ] `GET /rest/companies?limit=1` with the cached token returns 200 +
real data
- [ ] `POST /graphql { __typename }` returns 200
### Settings shell
- [ ] Settings nav matches main app drawer padding; sections collapse;
Exit Settings button aligns with the workspace links above
- [ ] Active nav items have a right-gap (cleaner active state)
- [ ] Content area capped at 880px
### Verify
- [ ] `npx nx typecheck twenty-front` passes
- [ ] `npx nx typecheck twenty-server` passes
- [ ] `npx nx lint:diff-with-main twenty-front` passes
- [ ] `npx nx lint:diff-with-main twenty-server` passes
Create the necessary tooling to listen to metadata events and plug it to
the front components. Now we have a hot reload like experience when we
edit a component in an app.
## Backend
- Split `EventWithQueryIds` into `ObjectRecordEventWithQueryIds` and
`MetadataEventWithQueryIds`
- Publish metadata event batches to active SSE streams in
`MetadataEventsToDbListener`
## Frontend
- Create a metadata event dispatching pipeline: SSE metadata events are
grouped by metadata name, transformed into
`MetadataOperationBrowserEventDetail` objects, and dispatched as browser
`CustomEvents`
- Add `useListenToMetadataOperationBrowserEvent` hook for consuming
metadata operation events filtered by metadata name and operation type
- Rename `useListenToObjectRecordEventsForQuery` to
`useListenToEventsForQuery`, now accepting both
`RecordGqlOperationSignature` and `MetadataGqlOperationSignature`
- Implement `useOnFrontComponentUpdated` which subscribes to front
component metadata events and updates the Apollo cache when the
component is modified
- Add `builtComponentChecksum` to the front component query and appends
it to the component URL for browser cache invalidation
This PR handles SSE event stream edge cases.
- When a pod restarts, the front clients have to reconnect to SSE
- When the dev server restarts or is hot reloaded, the front client has
to reconnect to SSE
- When redis server restarts or the redis key is cleared for any reason,
the server has to recreate the event stream in redis, this can happen
when navigating for example.
- Log in / log out flow
With this PR we avoid error messages in the front end due to TTL or pod
crash, we implement a resilient way of reconnecting silently.
To avoid DDoSing our servers if pods crash or a full restart of the
cluster is made, we evenly space retry attempts to reconnect from all
the clients, to avoid n clients reconnection at the same time, we use a
random wait time between 0 and a constant max wait time (set to 2 mins
for now). This is the cheapest and most effective solution, clients who
want to force reconnect have to refresh or navigate to another page.
Fixes https://github.com/twentyhq/core-team-issues/issues/2045
This PR update the redis subscription iterator wrapper with an heartbeat
system. Heartbeat interval are based on event stream TTL. Those refresh
the event stream TTL and active streams in redis.
I also cleaned a few functions that were not used anymore.

- new channel EVENT_STREAM_CHANNEL based on event stream id
- on event, perform the matching and publish only to the right streams
- store a list of active streams per workspace
- store the user id along with the queries for each stream
Bonus:
- remove onSubscriptionMatch
- moved a few gql types to twenty shared to re-use in server
- added a new endpoint, onEventSubscription that expect a streamId to
create a connection
- two new endpoints to store queries in Redis
- updated the existing batch channel to directly use object record type
