# 06 Ticket Creation and Backlog

## Goal

Implement the first ticket creation flow and establish backlog as the default intake for all new work.

## Requirements

- Tickets must belong to exactly one project.
- A ticket stores at least:
    - immutable ticket key
    - title
    - description
    - acceptance criteria
    - type
    - priority
- New tickets always start in backlog.
- Ticket keys must follow the format `PROJECTKEY-INDEX`.
- The sequence index is project-local, increasing, and immutable.
- Ticket titles are not unique and must not be used as identifiers.
- Provide backlog listing for a project.

## Acceptance Criteria

- Creating a ticket in project `AUTH` produces keys like `AUTH-1`, `AUTH-2`, and so on.
- Newly created tickets appear in backlog, not in a board column.
- Duplicate titles are allowed.
- Ticket creation is guarded by the project's `create` permission.

## Out of Scope

- Bulk ticket creation
- Attachments
- Comments as a discussion system
