## Note for agents

Some agent-wallet APIs block transactions that move tokens out of the wallet (seed burns in plant(), $HARVEST payment in buySeedHarvest()) at the provider's risk engine. Value-in calls (freeMint, claimDailySeeds, harvest) pass. If blocked, the same actions work on the website via wallet connect in the wallet app's browser.
