Status "%s" is marked as the status for closing tasks as dup

Error message

Status "%s" is marked as the status for closing tasks as duplicates, but it is not a closed status. It should be a closed status.

What it means

A status marked "special": "duplicate" is the status applied when a task is closed as a duplicate, and it must be a closed status. The validator's SPECIAL_DUPLICATE case throws when that entry lacks "closed": true, since merge/duplicate handling assumes the target status closes the task.

Solutions

1. Set "closed": true on the status that carries "special": "duplicate".
2. Model your duplicate status on the shipped one: {"duplicate": {"name": "Duplicate", "closed": true, "special": "duplicate", ...}}.
3. After any status edit, verify the three special statuses (default/closed/duplicate) all satisfy their open/closed requirements.

Example fix

// before
'duplicate' => array('name' => 'Duplicate', 'special' => 'duplicate'),

// after
'duplicate' => array('name' => 'Duplicate', 'closed' => true, 'special' => 'duplicate'),

foreach ($statuses as $constant => $spec) {
  if (idx($spec, 'special') === 'duplicate' && empty($spec['closed'])) {
    throw new InvalidArgumentException("Duplicate status '$constant' must set closed: true");
  }
}

When it happens

Trigger: maniphest.statuses entry like {"duplicate": {"name": "Duplicate", "special": "duplicate"}} without "closed": true — typically after renaming or hand-rebuilding the status list.

Common situations: Customizing statuses and rewriting the duplicate entry from an open-status template. Removing 'closed' from several statuses in a batch edit and accidentally including the duplicate one.
