OrderAmendCancelManager

exec.order_amend_cancel_manager

Execution planned Spec ready frozen

Owns every amend and cancel operation against the CLOB for orders Polytraders has placed.

What it does

Owns every amend and cancel operation against the CLOB for orders Polytraders has placed. Strategies do not cancel directly — they emit an OrderAdjustment intent which this bot validates, sequences, and submits via the EIP-712 v2 envelope. Maintains a strict monotonic intent sequence per order so cancels can never race amends.

Why it matters

If this fails	Consequence
Race conditions on cancel/amend	Without a single sequencer, two strategies can race each other to amend the same order, producing inconsistent CLOB state.
Phantom cancels	A cancel that fails silently leaves an order resting that strategy code believes has been killed; mismatched state causes self-trades and over-positioning.
Amend bypasses risk	An 'amend size from 100 to 500' looks like a cancel-and-place but bypasses Risk if not routed through this bot.
