Move scheduled swap price calculation from registration to execution time

[johnson86tw]

Currently, swap parameters (sqrtPriceLimitX96, amountOutMinimum, fee) are calculated at job registration time and encoded into the UserOp. When the backend executes scheduled swaps later, these parameters are often stale due to price fluctuations, causing swap failures.

SAManager/src/lib/scheduling/registerJob.ts

Lines 46 to 57 in c05925e

	const { sqrtPriceLimitX96, amountOutMinimum, fee } = await getSwapParameters(client, swapParams)
	execution = {
	to: ADDRESS.ScheduledOrders,
	value: 0n,
	data: INTERFACES.ScheduledOrders.encodeFunctionData('executeOrder', [
	jobId,
	sqrtPriceLimitX96,
	amountOutMinimum,
	fee,
	]),
	}

Current Flow

1. User schedules swap → calculates price parameters with current market data
2. Backend stores UserOp with encoded parameters
3. Backend executes UserOp later → parameters may be outdated → swap fails

Proposed Solution

Move price-sensitive parameter calculation to execution time:

1. Registration: Store swap intent (tokens, amount, user preferences) instead of exact parameters
2. Execution: Backend calculates fresh price parameters using current market data
3. Safety: Preserve user-defined minimum output amount as absolute floor

Files to modify

• src/lib/scheduling/registerJob.ts - Remove price calculation from registration
• SAManaber-backend - Add logic to calculate fresh parameters at execution
