InvalidInstructionData (#15999) on Solana same-chain swaps via DFlow router
Started happening consistently around March 10. Was rare before that.
Solana same-chain swaps (memecoin → SOL) are failing during simulation with AnchorError #15999 InvalidInstructionData on DF1ow4tspfHX9JwWJsAb9epbkA8hmpSEAtxXy1V27QBH, instruction SwapWithDestination. Only happens when the quote routes through DFlow.
Forcing includedOriginSwapSources: ["jupiter"] avoids the error but breaks routing for most pump.fun tokens (NO_SWAP_ROUTES_FOUND), so not a real fix.

The instruction fails almost instantly (21k of 803k CU), so it looks like the instruction data is malformed rather than a liquidity/routing issue.
Was there a recent change to the DFlow integration or on-chain program around March 10? And is there any way the quote API could detect this and fall back to another router automatically?
