## Summary
Replaces the single-screen partner-application modal with a **4-step
wizard** on the public form, and points the route's upstream at the new
`submit-partner-application` HTTP logic function in the twenty-partners
SDK app.
After design review, the Expertise step landed on the validated
**Category + Skills** model: a small set of *stable* macro categories
the partner operates in, plus a *free, semi-structured* Skills field for
the concrete things that differentiate them (React, SAP, Shopify, …).
Companion PR (partners-app side): #21040
## ⚠️ Deployment notes
Before this can ship to prod, the website worker needs a new env var:
- **Add `PARTNER_APPLICATION_SECRET`** to the deploy config at
https://github.com/twentyhq/twenty-infra/tree/main/cloudflare/website.
Without it the route returns `503` ("Partner application endpoint is not
configured.").
- The value must **match** the `PARTNER_APPLICATION_SECRET` workspace
variable set in the partners workspace UI (Settings → Apps → Twenty
Partners → Variables) — that's how the handler authenticates the
incoming `X-Application-Secret` header.
- `PARTNER_APPLICATION_WEBHOOK_URL` also needs repointing from the TFT
webhook to the logic-function URL
(`https://partner.twenty.com/s/partner-applications` or equivalent) at
the same time.
## Wizard
- 4 steps inside `Modal.Root`: **Identity → Profile → Expertise →
Commercials**. Step-dot indicator, per-step required-field gating, reset
on close. The big serif hero shows **only on step 1**; later steps use
the compact `STEP n OF 4 · NAME` strip to reclaim vertical space.
- **Profile** captures Type of team (Solo/Agency), LinkedIn, City,
Country, Languages. Country uses the searchable Select (placeholder-only
label).
- **Expertise = Category + Skills + Notes:**
- **Category** — multi-select cards over 5 macro categories (`ADVISORY`,
`SOLUTIONING`, `DEVELOPMENT`, `HOSTING`, `SUPPORT`), each with a
one-line description + examples. (Replaces the old draft `partnerScope`
enum; the backend keeps the field name — see #21040.)
- **Skills** — free tag input with a clickable suggestion row + keyboard
autocomplete (↑/↓/Enter/Esc) and "add your own". Empty by default.
- **Notes** — one free textarea (merges the former `workspaceUrl` +
`customerReferences`), reviewed manually.
- `deploymentExpertise` removed from the form (covered by the Hosting
category).
- **In-modal success view** on submit ("Thanks, / we'll be in touch!")
with a Close button — replaces the old silent close.
- Removes the partners-page "Which partner program is right for you?"
three-cards section.
## Design-system primitives
- **`Form.Select`** — searchable popup whose dropdown is **portaled to
`<body>`** (fixed, anchored to the trigger, flips up, height-capped) so
the modal's `overflow`/`transform` can't clip it; pointer events are
stopped so clicking inside it doesn't dismiss the dialog.
- **`Form.TagInput`** — optional `suggestions` prop adds the suggestion
row + autocomplete menu (used by Skills); behaviour unchanged when no
suggestions are passed.
- **`CategoryCardSelect`** — compact multi-select cards.
- `Form.MultiSelect`, `Form.Currency`.
## Validation & payload
- **Single validation source:** client and server share Zod field
schemas (`partner-application-field-schemas.ts`). The reducer validates
via those instead of hand-rolled regexes, so client and server agree by
construction (e.g. both reject non-TLD URLs).
- **Typed request body:** `buildPartnerApplicationRequestBody(state)`
returns a typed `PartnerApplicationRequest` (unit-tested);
`handleSubmit` just serializes it.
- Payload is camelCase matching the logic-function input;
`applicationNotes` replaces `workspaceUrl`/`customerReferences`.
- Auth: the upstream call carries an `X-Application-Secret` header
backed by `PARTNER_APPLICATION_SECRET` (handler-enforced — the SDK's
`isAuthRequired` only accepts user-session JWTs, not workspace API
keys). The webhook-URL env uses `z.url()` (not `z.httpUrl()`) so
`http://localhost:2020/...` dev destinations parse.

## Tests
- **62 passing** across reducer, Zod schema, route, the new
payload-builder suite, and Form helper suites. `npx tsc` clean, `nx
lint:diff-with-main` clean, Lingui catalogs regenerated (French slots
are a follow-up).
## Test plan
- [ ] `/partners` → "Become a partner" → wizard opens on Step 1 (full
hero)
- [ ] Identity: name / work email / company → Next
- [ ] Profile: pick **Type of team**; search country ("fra" → France);
pick languages → Next (compact header from here on)
- [ ] Expertise: select 1+ **Category** cards; add **Skills** (click a
suggestion, type one + Enter, drive the ↑/↓ autocomplete); optionally
fill **Notes**
- [ ] Country dropdown opens without being clipped by the modal, and
clicking inside it does **not** close the wizard
- [ ] Commercials → Submit → **in-modal "Thanks, we'll be in touch!"**;
Network shows POST `/api/partner-application` `200`
- [ ] Partner record lands with the chosen categories in `partnerScope`,
plus `skills`, `applicationNotes`, `slug` from company, `reviewed:
false`, `partnerTier: 'NEW'`
- [ ] Re-submit same email + different city → Partner updates;
`validationStage`/`reviewed`/`partnerTier` preserved
- [ ] Back/Next preserves entered values; Reset on close; mobile
single-column / chips wrap
