# dfs:position-permission — Ammora SDK 0.3.8

dfs:position-permission -- <vault> <pool> <concentrated|compounding> <nftId> <fee|reward|revoke>. Exact fee/reward bits only. Concentrated uses Manager NFTs; raw NFT approval is a broader, separate operation.

## Context and execution

GIWA Sepolia 91342. Public SDK 0.3.8, Math 0.3.0. Source revision: `a9b3fd798fa51495e8defec99a25de59e4d70672`.
Install the SDK in your app, or prepare the example project using the local setup guide for its npm commands. Review the entry source and guide for required arguments, roles and deployment selection. `AMMORA_SEND=0` does not turn send-only commands into previews. Never put CLI keys in a browser or resend an uncertain transaction.

Command: `npm run dfs:position-permission -- <arguments from the source below>` (`tsx src/dfs/position-permission.ts`). Omit `--` and arguments when the source accepts none.

## Supporting files

Keep relative paths intact. Local imports are listed recursively; JSON templates are choices to review, not approved inputs. Runtime-selected files and wallet/environment setup still follow the detailed guide.

## AI implementation checklist

Use the actual SDK exports and parameter types in the linked files. Start with reads and unsigned plans where supported. Use a connected wallet for browser signing. Preserve raw integer units, exact approvals, caller authority, deadlines and receipt reconciliation. Report local checks separately from live-chain verification.
