event-rally — agent notes

Rally is a single-event RSVP page on the Hanzo stack, forked from the canonical hanzo-starter. Vite + React 19 + @hanzo/gui (UI) + @hanzo/iam (auth) + @hanzo/base (data). Keep it minimal and REAL — every surface must build and run, no fabricated UI.

The app

One event, one page. Guests see a color-flooded hero (date · title · place) with a cream ticket-stub RSVP card; hosts sign in to manage it.

• Event page (views/event.tsx) — public landing: the flooded hero + the ticket stub. Signed out, the stub's CTA is a PKCE sign-in; signed in, it is the live RSVP form.
• RSVP (views/rsvp.tsx) — going / can't-make-it, a guest headcount, and a note → a row in the rsvps collection.
• Attendees (views/attendees.tsx) — host guest list with live counts (heads coming · replied yes · spots left).
• Edit (views/edit.tsx) — host creates/updates the single event row.
• Host shell (views/host.tsx) — the signed-in nav over those three.

One way, decomplected

• Providers (src/providers.tsx) mount in the canonical order every Hanzo surface ships: GuiProvider → IamProvider → BaseProvider. BaseProvider gets a BaseClient carrying the IAM access token; it is rebuilt when the token changes (src/lib/base.ts baseAs). That single seam makes every useQuery/useMutation org-scoped to the signed-in user.
• Env is one place (src/env.ts), read from import.meta.env.VITE_*. The IAM client id is VITE_IAM_CLIENT_ID (a per-app client provisioned at deploy; falls back to the shared hanzo-app).
• Look is one place (src/theme.ts) — a single striking accent over ink, with a cream ticket. Raw hex is used on gui color props deliberately.
• UI is one system — @hanzo/gui primitives only (no second kit, no Tailwind).

Gotchas (do not regress)

• @hanzo/gui under Vite needs three things in vite.config.ts (it is the Tamagui line; the in-browser builder runtime can't do this, which is the whole reason this ships as a real repo): (1) alias react-native → react-native-web, (2) define process.env.TAMAGUI_TARGET / NODE_ENV / __DEV__, (3) dedupe react/react-dom/react-native-web. No Tamagui compiler, no one, no Expo — the optimizer is a perf pass, not a correctness one.
• @hanzo/gui props are Tamagui LONGHAND with this v5 config: alignItems/justifyContent/backgroundColor/padding/borderRadius/ textAlign — NOT the items/justify/bg/p/rounded/text shorthands. Shorthands pass at runtime but FAIL tsc.
• A Button's frame is a Stack. It takes stack style props (backgroundColor, border*, height, flex, pressStyle) but NOT text props. Style the label on Button.Text (color/fontSize/fontWeight) — the Cta helper in views/ui.tsx wraps this once. onPress (not onClick); Input uses value/onChangeText and inputMode (not RN keyboardType); multiline text is TextArea, not <Input multiline>; placeholderTextColor takes a color token / CSS name, not raw hex.
• PKCE storage is localStorage (not sessionStorage) so the verifier/state survive the round-trip to hanzo.id.
• schema.sql is the data contract. It is the databaseSchema DDL the deploy translates into Base collections (provisionBaseFromDDL). Base manages id/created/updated/owner/org and enforces the org rule @request.auth.org_id = org; never re-declare those. Keep it in lockstep with src/lib/event.ts + src/lib/rsvp.ts.

Deploy contract (Hanzo Cloud)

• Static SPA: npm run build → dist/, served at <slug>.hanzo.app from object storage (the *.hanzo.app published-sites edge). No server process.
• On publish, schema.sql → provisionBaseFromDDL creates the collections (org-scoped, IAM-native). Runtime read/write is browser → VITE_HANZO_BASE_URL with the IAM token.
• IAM redirect registration is the one external requirement: the IAM client (VITE_IAM_CLIENT_ID, default hanzo-app) must allow this origin's /auth/callback. Production needs a https://*.hanzo.app/auth/callback wildcard on the shared client (or a per-app event-rally client).

Proven

tsc --noEmit clean · vite build → dist/ · login() performs a real PKCE S256 redirect to hanzo.id.

Build

CI (.github/workflows/ci.yml) runs npm ci && npm run typecheck && npm run build — build-verification only, NEVER a container image (Hanzo Cloud owns deploys; do not build images locally).
