Geano's Secret Rolls is a Foundry VTT module that adds a true "Secret Roll" option to the roll mode menu.

Unlike the standard "Blind GM Roll" (which hides results from everyone but uses a placeholder card) or "Private GM Roll" (which shows a gray box to players), a Secret Roll is completely invisible to all other players. It appears only to the person who rolled it and the Game Masters.

• New Roll Mode: Adds "Secret Roll" to the chat roll mode dropdown.
• True Invisibility:
  • Roller: Sees the full roll result (dice, banners, cards).
  • GM: Sees the full roll result.
  • Others: See NOTHING. No "Unknown Roll" card, no "Something happened" notification, no sound. It is as if the roll never happened.
• System Compatibility: Works by intercepting the roll and converting it into a private "Ghost Message", ensuring that even complex systems like D&D 5e or Pathfinder do not accidentally leak information via "Unknown Roll" cards.

1. Select Secret Roll from the roll mode dropdown at the bottom of the chat log.
2. Make your roll (attack, ability check, or /r 1d20).
3. The result will be whispered to you and all GMs.

This module uses a "Ghost Roll" technique:

1. It intercepts the preCreateChatMessage hook.
2. If the mode is "Secret", it cancels the original system message.
3. It manually renders the system's chat card and dice HTML.
4. It creates a new, purely cosmetic WHISPER message containing that HTML.

This ensures that the Game System (e.g., dnd5e) cannot interfere or try to "sanitize" the roll for other players, guaranteeing total privacy.
