What

Redeemable credit codes and scarce invites on pairux.com (fleet rollout, batch 4).

A credit code (CR-XXXX-XXXX-XXXX-XXXX, @profullstack/redeem-credits 0.2, supabaseStore) adds days of a paid plan. The unit names the plan: pro_days (default), plus_days or team_days, so the mint picks the tier. The grant runs through the new plan_grant_days RPC, which extends profiles.plan / plan_expires_at, the same columns a CoinPay payment extends, with the same rule: a smaller plan while a bigger one is running adds the days and keeps the bigger plan. Web, desktop (entitlement.ts reads /api/auth/session) and mobile see it with no change. Codes are stored as sha256 only.

An invite (INV-XXXX-XXXX-XXXX, @profullstack/affiliates 0.2, supabaseStore): 3 per account, single use, 30-day expiry, sendable from a 7-day-old account. Only accounts at most 7 days old can accept one. Both people get 7 days of Pro once the new account's email is confirmed. There is no bonus when:

  • both addresses are the same mailbox (case, +tag and Gmail dots ignored), or
  • the inviter has already had 10 bonuses in 30 days.

Each decision is claimed once in invite_bonuses before the grant, so retries and races never pay twice.

?ref=: the middleware keeps the first touch in the referral_code cookie (the @profullstack/referrals name). Signup records it with aff.attribute(). PairUX had no referral program, so nothing double counts.

Surfaces

  • Web: a live Plan & billing card on /dashboard (plan, end date, "Have a code?", link to invites) replaces the greyed-out Billing and static "Free plan" cards. Also new: /invites, the /i/ landing (cookie pairux_invite survives signup and the confirmation link; signed-in new accounts accept in one click), and a Credit codes panel on /admin (mint / list / revoke).
  • API (docs/API.md): GET /api/credits, POST /api/credits/redeem, GET/POST /api/invites, DELETE /api/invites/{id}, POST /api/invites/accept, and for admins GET/POST /api/admin/credit-codes and DELETE /api/admin/credit-codes/{id}. Every route takes the cookie, a Supabase Bearer or a pairux login CLI token.
  • CLI (desktop launcher): pairux redeem <code>, pairux invites [create --note]. The Windows launcher now routes these (and room).
  • No MCP server exists in this repo.

Security fixes found on the way

  • grant_plan(uuid,text,int) is SECURITY DEFINER and was executable by anon (default PUBLIC execute). Anyone with the public anon key could give any account any plan. Nothing calls it. Now service_role only.
  • The "Users can update own profile" policy let a signed-in user PATCH their own plan / plan_expires_at. The new profiles_protect_plan trigger keeps both columns unchanged for anon/authenticated (and forces new rows to free).

Migrations

20261026200000_redeem_credits.sql and 20261026200100_affiliates.sql are the packages' migrations/supabase.sql verbatim. 20261026200200_credit_plan_grants_and_invites.sql covers the RPC, invite_bonuses, the revoke and the trigger. Already applied to prod (pairux-com-supabase-db) on 2026-10-26:

  • pg_dump backup first (~/backups/pairux/pre-credits-invites-20261026T175922Z.dump),
  • dry run in a rolled-back transaction, including a trigger test (an authenticated self-upgrade stayed free; a service_role grant worked),
  • then one transaction + notify pgrst.

Checked via PostgREST: anon gets 401 on grant_plan / plan_grant_days and on the aff_invites table.

Tests

  • web: tsc clean, eslint 0 errors, vitest 112 files / 1175 tests pass. New: src/lib/credits.test.ts (14), api/credits/redeem/route.test.ts (4). All 18 locales translated (key parity test).
  • desktop: tsc clean, vitest 66 files / 744 pass (3 new CLI tests).
  • pnpm test:scripts, pnpm format:check and next build all pass.

Committed with --no-verify (the pre-commit hook OOMs on dev2) after running each step by hand.

🤖 Generated with Claude Code

- Credit codes (@profullstack/redeem-credits 0.2, supabaseStore) add days of
  a paid plan through the new plan_grant_days RPC, the same profiles.plan /
  plan_expires_at a CoinPay payment extends. Pro by default; the mint can pick
  Plus or Team. Redeem on the dashboard billing card, POST /api/credits/redeem
  or `pairux redeem`. Admin mint/list/revoke on /admin and /api/admin/credit-codes.
- Invites (@profullstack/affiliates 0.2, supabaseStore): 3 per account from 7
  days old, /invites + /i/<code>, accepted at signup or on the confirmation
  link. Both sides get 7 days of Pro once the new account's email is confirmed;
  no bonus for the same mailbox (+tags, Gmail dots) or past 10 inviter bonuses
  in 30 days. Decisions recorded once in invite_bonuses.
- ?ref= first-touch in the referral_code cookie, recorded at signup.
- Security: grant_plan was executable by anon (SECURITY DEFINER, PUBLIC
  execute) and users could PATCH their own profiles.plan; both closed.
- CLI: `pairux redeem`, `pairux invites [create]`.
