## ADDED Requirements

### Requirement: Process discovery

WhiteMagic SHALL attach to a target process discovered by process name, window title, or window handle, and SHALL enumerate candidate processes. An ambiguous match MUST fail deterministically rather than attaching to an arbitrary candidate.

#### Scenario: open by process name
- **WHEN** a target is opened by a unique process name
- **THEN** it MUST attach to that process

#### Scenario: open by window title
- **WHEN** a target is opened by a window title
- **THEN** it MUST attach to the process owning the window with that title

#### Scenario: open by window handle
- **WHEN** a target is opened by a window handle
- **THEN** it MUST attach to the process that owns that window

#### Scenario: ambiguous match is rejected
- **WHEN** more than one process matches the given name or title
- **THEN** the open MUST fail and surface the set of candidate processes rather than picking one

#### Scenario: enumerate candidates
- **WHEN** candidate processes are enumerated
- **THEN** the result MUST list the processes eligible to be opened
