App manifests could point the logo and screenshots at either external
URLs or public folder paths, and that was handled inconsistently across
install, sync and the marketplace.
This makes assets always bundled files:
- Manifests now use `logo` and `galleryImages` (a `string[]` of public
folder paths) instead of `logoUrl` and `screenshots`. The old fields
still work but are deprecated. Gallery order comes from the array index.
Normalization (deprecated-field migration, and warning about + ignoring
external URLs) happens in `defineApplication`, so the warnings surface
at define time.
- Logo is stored as a File record (`logoFileId`).
- The registration gallery is configured via a `settings` jsonb column
on `applicationRegistration` (`{ galleryImages: string[] }`) — populated
from the manifest, read by the marketplace detail (falling back to the
legacy `screenshots` column, then the manifest). No dedicated gallery
table.
- The marketplace detail DTO and front now use `galleryImages`.
Verified against a local Postgres: the fast instance commands run with
no pending-migration diff, the schema is correct, and the server boots.
Typecheck, lint, codegen and the application unit tests pass.
Not included yet: rehosting assets into storage for npm catalog and
tarball registrations, versioned cache busting on the serving route, and
a backfill for existing installs.

## What & why
This adds a **guided tutorial** that teaches the Twenty SDK by building
one real, useful app end to end — plus the finished app itself, ready
for the marketplace.
The app, **Document Generator**, turns reusable templates into
personalized documents using CRM data: write a template once with
`{{placeholders}}`, then generate a filled-in document for any Person or
Company from the command menu, an AI agent, or a workflow.
## Two parts
**1. The app — `packages/twenty-apps/public/document-generator`**
Each capability maps to one tutorial chapter:
- **Data:** `documentTemplate` + `document` objects, fields, and a
bidirectional relation
- **Logic:** a single `generate-document` handler exposed as an **AI
tool**, a **workflow action**, and an **HTTP POST route**; plus a public
**HTML view route**
- **UI:** two views + sidebar navigation, a **command-menu item** (on
Person selection) that opens a **React front component**
- **AI:** an agent + skill; a default application role; marketplace
metadata + logo
- **Tests:** unit tests for the template renderer + an install
integration test
**2. The tutorial —
`packages/twenty-docs/.../apps/tutorials/document-generator/`**
A six-chapter series under **Developers › Apps › Tutorial** (Overview →
Data model → Generating documents → HTTP routes → Building the UI → AI
agent → Publishing). Minimal prose, paste-ready code, inline links to
the matching reference pages, and real screenshots. Registers a new
"Tutorial" nav group and regenerates `docs.json` + the navigation
template.
## Verification
Validated against a running Twenty instance (`twenty-app-dev` on
`:2020`):
- `twenty dev --once` installs cleanly (28 metadata objects created)
- Generated a real document from a Person — placeholders resolved (name,
job title, `company.name`, email), zero missing tokens
- Command menu → front component → generate flow works in the UI
- Public HTML view route renders the document
- App gates green: `yarn lint` (0/0), `yarn typecheck`, `yarn test:unit`
(7/7)
All screenshots in the tutorial are captured from this run.
## Notes
- Left out per-app CI workflows (`.github/workflows`) to keep scope
tight — happy to add them if wanted.
