## Summary
The email-change confirmation toast rendered a trailing `&sb=` ("...sent
to the other email&sb="). The dashboard parsed the auth-redirect URL
fragment with a naive `split('#message=')` that grabbed everything after
the key, including the empty `sb` origin marker the auth service appends
to every redirect fragment (an intentional, server-side Supabase-Auth
identifier so clients can tell a Supabase redirect from a third-party
OAuth one). The marker is working as designed; the bug is that the
dashboard wasn't parsing the fragment as URL params, so I fixed the
parse rather than the marker.
## Changes
- Parse the redirect fragment with `URLSearchParams` via a new
`parseRedirectMessage` helper, reading only the `message` key. Any other
trailing fragment param (the `sb` marker, or future ones) is now ignored
instead of being concatenated into the toast.
- Drop the manual `+`-to-space replacement. `URLSearchParams.get()`
already decodes form-encoded values, and the old `.replaceAll('+', ' ')`
would have clobbered a legitimately encoded `+`.
- Add unit tests for the helper: marker stripped, no hash, no `message`
key, `message` not first, and percent-encoded `+` preserved.
## Testing (Vercel preview)
The toast only reads the URL fragment, so the redirect can be simulated
directly. Do not use the real email round-trip on the preview: a real
confirm-link click is redirected to prod (the backend sets
`redirect_to`), not the preview build.
- [x] On the preview, log in and open the account preferences page with
this fragment appended:
`/account/me#message=Confirmation+link+accepted.+Please+proceed+to+confirm+link+sent+to+the+other+email&sb=`
— toast shows the clean sentence with no `&sb=`.
- [x] Open the same page with no fragment — no toast fires.

## Summary by CodeRabbit
* **Bug Fixes**
* Improved how success messages are read after redirect in account
identity preferences, so notifications now display the correct text more
reliably.
* Supported messages with spaces and special characters, including cases
where the message appears later in the URL fragment.

How it works
Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.
Architecture
Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.
- Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
- Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
- PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
- GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
- Storage a RESTful API for managing files in S3, with Postgres handling permissions.
- pg_graphql a PostgreSQL extension that exposes a GraphQL API.
- postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
- Kong is a cloud-native API gateway.
Client libraries
Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
