# 📦 Tia — Storage Quota & Member Limits
> Free-tier guardrails before beta. Branch `feature/quota-and-member-limits` (NOT merged to main as of 2026-05-27).

## Limits
- **1 GiB** storage / family · **2 members** / family (free tier)

## Key files
- `src/lib/quota.ts` — enforcement (pure fns + queries)
- `api/upload`, `api/memories/[id]/confirm`, `api/invites`, `api/storage-usage`
- `components/StorageMeter.tsx` · `__tests__/quota.test.ts` (44 tests pass)
- `drizzle/0007_subscription_status.sql`

## Design calls
- Usage **derived** (SUM), never accumulated ([[Decision Log#TD-001]])
- `tier` is the plan indicator; `isPaidFamily(tier)` abstraction ([[Decision Log#TD-002]])
- Downgrade = **freeze** (keep members, block new invites)

## Status
- [ ] **Apply migration 0007 on staging before merge.** Do not push to main yet.
