## Summary - Closes [#34](#34) - Companion for [chat_web_app#75](ai_ml_operations/chat_web_app#75) (portal cancel/change local sync) - Soft-delete `DELETE /api/user/` for the authenticated user only: `deleted=True`, `is_active=False`, hide conversations, blacklist outstanding refresh tokens; staff self-delete rejected - Stripe `customer.subscription.updated` / `deleted` webhooks sync plan status, `cancel_at_period_end`, and `current_period_end`; checkout assigns plan from `metadata.plan_slug` - **UserAuthEvent audit**: `account_deleted`, `subscription_started` (first active plan), `subscription_updated` (plan/status/cancel changes) — visible on user admin - Document FE contract in README (endpoint, response, post-delete logout) ## Test plan - [ ] `uv run python manage.py test chat_backend.tests.test_views_users.CustomUserSelfDeleteTestCase finance.tests` - [ ] Authenticated `DELETE /api/user/` soft-deletes self, hides conversations, blocks re-login, writes `account_deleted` auth event - [ ] Checkout / Backer assign writes `subscription_started`; portal cancel/change writes `subscription_updated` - [ ] Anonymous / staff self-delete rejected; body cannot target another user - [ ] After portal cancel, webhook sets `cancel_at_period_end` / `canceled` on `GET /finance/subscription/`Reviewed-on: #39
