What

Hackathons are now unlocked by a NaN plan (Community, Inference or Premium). cloud-api (fix/open-signup-feedback) gates hackathon register, submission PUT, reassign and vote with a live check and answers an account without a plan with:

403 {"error":"entitlement_required","capability":"hackathons","unlockedBy":["community","inference","premium"]}

The website mapped that badly: RegisterForm showed "not eligible" for any 403, and VoteButton, SubmissionForm and ReassignForm showed a generic error.

All four now show a membership notice with a CTA:

• EN: "Hackathons are for NaN members. Join the community (from 14.99€/month) to take part." → Join the community
• ES: "Los hackathons son para miembros de NaN. Únete a la comunidad (desde 14,99 €/mes) para participar." → Únete a la comunidad

The CTA goes to https://cloud.nan.builders/signup?plan=community. These forms are only reachable with a session, and the platform's /signup already redirects a signed-in account to /welcome?plan=community, which goes straight to checkout. So one link covers both cases. not_eligible and every other code keep their current messages.

How

• src/lib/eventEntitlement.ts: isEntitlementRequired(), the CTA URL and the strings type.
• src/components/events/MembershipRequired.tsx: a shared notice, with a compact variant for the vote button.
• RegisterForm and VoteButton move their error mapping into pure exported functions (registerErrorKey, voteOutcome), so it can be tested. SubmissionForm and ReassignForm check entitlement_required before the not_eligible and generic fallbacks.
• New events.membership strings in i18n/en.json and i18n/es.json, passed in by the four event pages.

Tests

Written first, in src/tests/pages/eventsEntitlement.test.ts:

• error detection, and that other codes are not swallowed;

• the CTA URL;

• EN/ES copy;

• SSR render of the notice;

• the register and vote mapping tables, including the unchanged codes;

• source-order guards for the submission and reassign handlers;

• every page passes the strings.

• npm run build: passes

• npx astro check: 0 errors

• npx vitest run: 87 files, 2554 tests, all passing

• Visual check with agent-browser against a mock cloud-api returning the 403: register form error state in EN and ES, at 1440px and 390px. The notice and link render, with no horizontal scroll.

Deploy note

Merge and deploy this AFTER the cloud-api fix (fix/open-signup-feedback), because this site deploys to prod on merge. It is harmless either way: until cloud-api returns entitlement_required, the new branch is never hit and the forms behave exactly as today.
