17//   - tokenPath: registry key/path of the token contract whose balance is queried
18//
19// Returns:
20//   - balance: token units held by the configured community-pool address, or 0 when validation fails
21//   - err: nil when tokenPath is valid and registered; non-nil for an invalid or unregistered tokenPath

32// TransferToken transfers token units from the community pool to an address.
33//
34// Parameters:
35//   - cur: current realm context; callers use cross(cur) when crossing into this realm
36//   - tokenPath: registry key/path of the registered token to transfer
37//   - to: recipient address for the token units
38//   - amount: number of token units to transfer; transfer failure panics through the safe wrapper
39//
40// Only callable by admin or governance while withdrawals are not halted.
41// Governance is the recommended normal route. While governance is not yet
42// mature, admin access is retained for emergency-only use as an operational
43// policy, not a contract-enforced condition. Admin calls do not require an
44// approved proposal; emergency status is not checked and admin access does
45// not expire automatically.
