Tag along order

[mgretzke]

Introducing "Tag-Along" claims to the Tribunal protocol, enabling fillers to execute secondary claims derived from a successful primary fill.

Key Changes:

• New Functions:
  • fillTagAlong: Allows the filler of a source order to execute a linked tag-along claim. If the original order had price scaling applied, the tag-along claim amount is scaled proportionally.
  • fillAndDispatchTagAlong: Executes a tag-along fill and immediately triggers a dispatch callback (e.g., for cross-chain settlement) in a single transaction.
• Updated Dispatch Logic: Modified the dispatch function signature to accept a compactTypehash. This generalization allows the dispatch logic to verify and process both standard mandates and tag-along mandates.
• Access Control: Tag-along fills are restricted to the original filler of the source order to prevent front-running, except when the source order is cancelled (allowing state clearance/cancelled.

• Removed ERC7683Tribunal temporarily, because the contract exceeds the allowed size limit with the new additions.
