close_user_bundle_account

1. Load the GLAM state or program account required by the instruction and verify the signer.
2. Verify that the integration is enabled on the vault and that the caller has the required delegate permission or owner authority.
3. Validate the instruction-specific policy, then invoke the external protocol with the vault authority where required.
4. Close an empty Neutral user bundle account and remove it from GLAM external positions. - Permission requirement: CloseUserBundleAccount. - Policy: bundle_account must be present in NeutralPolicy::bundles_allowlist.

• The submitted accounts must match the declared account list, signer requirements, writable requirements, fixed program addresses, and account relationships shown below.
• The GLAM state account is the source of truth for owner, enabled integrations, delegate permissions, policies, assets, borrowable assets, timelock settings, mint linkage, and pricing records.
• The vault account must be the PDA controlled by the core protocol program and derived conceptually from the state account; instructions use it as the vault authority for SOL, token accounts, and external positions.
• The vault integration ACL must enable this integration before the instruction is accepted; that enablement is defined on the GLAM state account.
• If the signer is not the owner, the delegate ACL on the GLAM state must contain the exact protocol permission required by this instruction; registering a delegate alone is insufficient.
• Instruction-specific destination accounts must satisfy the external protocol's own account model; GLAM validates the accounts it needs for authorization and policy enforcement, then passes the remaining protocol accounts through CPI.
• The target account must be writable and controlled by the program or authority expected by the instruction.
• The rent refund destination or signer account must be writable because closing returns lamports to that account.
• Any protocol-specific empty-state requirement, such as zero balance, zero supply, no pending request, or no active position, must be satisfied before closure.
• The instruction metadata names CloseUserBundleAccount as the delegate permission for this instruction.
• Additional policy conditions documented for this instruction: Policy: bundle_account must be present in NeutralPolicy::bundles_allowlist.

Uses the standard Big Seven account pattern, plus the instruction-specific accounts below.

No arguments.

• Enable the Neutral integration program on the vault integration ACL before Neutral bundle actions.
• Delegate permission: CloseUserBundleAccount.

• The Neutral bundle depositor account must be initialized and the bundle must remain allowlisted.
