Félix Malfait d1a4e250cf fix(ai): converge every tab's transcript when a stream fails with partial output (#22494)
## Rationale

When a turn fails after emitting output, the partial assistant message
**is persisted** — but only the success path publishes the event
(`message-persisted`) that makes other tabs refetch. On failure, tabs
that weren't watching the live stream keep a stale transcript until
manual reload. (Error *visibility* itself already works — `stream-error`
reaches every subscribed tab — the gap is purely the
persisted-transcript sync. The original gap-analysis framing of this as
an error-visibility problem was wrong; this is the corrected scope.)

## Why this is the root cause, not a symptom patch

Turn settlement should converge subscribers regardless of *how* the turn
settled — success and failure both persist state that tabs need. The
failure path now publishes the same refetch-trigger event the rest of
the lifecycle uses, right after the terminal `stream-error`. No new
event type, no client changes: the existing guarded replay
(`firstLiveSeq === null`) already ensures tabs with a live view keep
their in-place error rendering while background tabs pick up the
persisted partial message and error state.

## User impact

Open the same thread in two tabs, have the turn die mid-answer in one:
the other tab currently shows the conversation frozen pre-turn until
reload. Now both converge to the persisted partial output plus the
failed-turn state within one refetch.

## Test plan

- [ ] CI green
- [ ] Manual: two tabs, kill the provider mid-stream in tab A → tab B
shows the partial message + error without reload

Installation

Cloud

The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.

Build an app

Scaffold a new app with the Twenty CLI:

npx create-twenty-app my-app

Define objects, fields, and views as code:

import { defineObject, FieldType } from 'twenty-sdk/define';

export default defineObject({
  nameSingular: 'deal',
  namePlural: 'deals',
  labelSingular: 'Deal',
  labelPlural: 'Deals',
  fields: [
    { name: 'name', label: 'Name', type: FieldType.TEXT },
    { name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
    { name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
  ],
});

Then ship it to your workspace:

npx twenty app:publish --private

See the app development guide for objects, views, agents, and logic functions.

Self-hosting

Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
