# 03 Ticket Branch Discovery by Ticket Key

## Goal

Show branches related to a ticket by matching configured repository branches against the ticket key prefix.

## Requirements

- Add a branches section to the ticket detail view.
- For each configured project repository connection, identify branches whose names start with the ticket key.
- A matching branch must be shown on the ticket when its name starts with the exact ticket key, for example `AUTH-42-...`.
- Present matches in a way that makes the repository source clear.
- The first implementation may use direct fetches or a simple cache, but it must not require a large background sync system.

## Acceptance Criteria

- A ticket with key `AUTH-42` shows branches such as `AUTH-42-login-form`.
- Branches that do not start with the ticket key are not shown.
- If multiple connected repositories contain matching branches, the ticket shows matches from each relevant repository.

## Out of Scope

- Commit listing
- Branch creation from inside KanbanGit
- Cross-ticket branch disambiguation beyond exact ticket-key prefix matching
