Deletes a stale message and ALL its translations across ALL locales.

This function removes the message completely from the system, including all singular and plural translations in every locale.

Arguments

• message_id - Integer ID of the message

Returns

• {:ok, stats} - Map containing deletion statistics:
  • :translations_deleted - Number of translations deleted across all locales
  • :message_deleted - Boolean indicating if message was deleted
• {:error, reason} - If deletion fails

Examples

iex> Kanta.Translations.Messages.delete_message(123)
{:ok, %{translations_deleted: 5, message_deleted: true}}

Merges two messages by moving all translations from one message to another.

This operation:

1. Deletes all existing translations from the target message
2. Moves all translations from the source message to the target message
3. Deletes the source message

This is useful when a stale message needs to be merged with its replacement (e.g., when msgid changes due to typo fixes or wording changes).

Arguments

• from_message_id - ID of the source message (will be deleted)
• to_message_id - ID of the target message (will receive translations)

Returns

• {:ok, target_message} - Target message with merged translations
• {:error, :not_found} - One or both messages not found
• {:error, reason} - Merge failed

Examples

iex> merge_messages(123, 456)
{:ok, %Message{id: 456, ...}}
