Struct ContextAccountDescriptor 

pub struct ContextAccountDescriptor {

    pub name: &'static str,
    pub kind: &'static str,
    pub writable: bool,
    pub signer: bool,
    pub layout_ref: &'static str,

    pub expected_owner: &'static str,
}

Schema descriptor for a single account field within a context.

Richer than the basic AccountEntry – captures the full Account DSL surface including kind, layout, policy, seeds, optionality, and the Anchor-grade lifecycle flags (init/close/realloc/has_one) that the Hopper Safety Audit’s ST2 closure requires client generators to consume.

Fields

name: &'static str

Field name in the struct (e.g. “vault”, “authority”).

kind: &'static str

Account wrapper kind (e.g. “HopperAccount”, “Signer”, “ProgramRef”).

writable: bool

Whether the account is writable.

signer: bool

Whether the account must be a signer.

layout_ref: &'static str

Layout name bound via layout = T, if any (empty string if none).

policy_ref: &'static str

Policy pack name bound via policy = P, if any (empty string if none).

seeds: &'static [&'static str]

PDA seed expressions as string representations.

optional: bool

Whether the account is optional (may be omitted by the caller).

lifecycle: AccountLifecycle

Lifecycle role the account plays in this instruction. Clients use this to synthesize appropriate builder helpers (findPda, initAccount, closeTo, etc.).

payer: &'static str

Name of the field whose key pays CPI fees / rent top-up for init or realloc. Empty if not applicable.

init_space: u32

Byte count required for init. None (represented as 0) if not applicable.

has_one: &'static [&'static str]

Fields listed in has_one = ..., required to equal the corresponding layout field by public key.

expected_address: &'static str

Address the caller must provide, if pinned via address = EXPR (base58 form for pubkey literals; empty string if not pinned).

expected_owner: &'static str

Program owner the account must be owned by, if pinned via owner = EXPR. Empty string means “owned by the current program”.
