package keeper
// custody_state.go holds the custody asset records (assetID → custody entry
// + sig ref + key version) for the x/hub custody runtime (P4-02-01,
// REQ-036). data-engineer territory (P4 phase-specific — removed after P4
// per PERSONAS.md).
//
// D-054: in-memory test store ONLY — the SDK in-memory store (dbm NewMemDB)
// is the substrate; NO real database, NO migration (simtest grade). The
// custody state is the closest thing to a data store in v0.5; there is NO
// real database (the SDK store is the substrate). data-engineer's role is
// narrow: ensure the custody state shape (assetID → custody entry + sig ref
// + key version) is consistent with the CustodyKeyring interface and
// supports rotation (D-058).
//
// State shape (consistent with CustodyKeyring interface, D-058):
// - assetID → CustodyEntry (assetID, holder-reach-id, partner-id, sig-ref,
// key-version, custody-status)
// - sig-ref is the opaque reference to the signature produced by
// CustodyKeyring.Sign on the custody-receive payload (stored so a
// later CustodyReleaseAsset can verify the release is authorized by
// the same key version that received the asset — rotation safety).
// - key-version is the CustodyKeyring active key version at the time of
// custody-receive (recorded so a post-rotation release can detect the
// key has rotated — the handler may require re-attestation).
//
// The custody state is store-backed (wraps an sdk.KVStore via a storeKey on
// the Keeper). The custody entry is JSON-marshaled (same pattern as
// x/partner/keeper/keeper.go AnchorCredential store — simtest-grade, no
// protobuf codegen).
//
// Lexicon note (REQ-012, A-542): "custody", "asset", "holder", "reach-id",
// "sig-ref", "key-version", "receive", "release" are all lexicon-clean.
// The inbound/outbound custody names follow A-542 (the banned storage
// terms are NOT used; CustodyReceiveAsset / CustodyReleaseAsset are the
// safe vision vocabulary). "holder"/"reach-id" (NOT the banned holder

package keeper

// - the registered custody services (service-id → CustodyService);
// - the lending primitive records (loan-id → LendingPrimitive);
// - the compliance attestation records (partner-id → attestation-ref, the
// store the ComplianceKeeper shim's IsCompliant reads — A-544).
//
// The Keeper also holds the two expected-keeper shims (PartnerKeeper for
// IsAnchorOnboarded on RegisterCustodyService; ComplianceKeeper for
// IsCompliant on CustodyReleaseAsset — A-544 compliance-before-custody).
// The shims are interfaces (G-003 — no struct import of x/partner/types);
// the concrete partner keeper satisfies them structurally.
//
// The Keeper holds the CustodyKeyring (D-058) — the custody key-share
// abstraction. v0.5 ships the in-memory test-only memKeyring impl
// (keyring_mem.go); real MPC/HSM backing is deferred (Year 3+). The

// 1. x/partner (PartnerKeeper) — the RegisterCustodyService handler asserts
// the operator-partner-id references an Onboarded Anchor Partner BEFORE
// registering the custody service. This is the P3→P4 edge: P3 ships the

// registration. The handler consults IsAnchorOnboarded(partnerID) via
// the shim; a non-Onboarded Anchor REJECTS the registration.
//
// 2. x/partner compliance (ComplianceKeeper) — the CustodyReleaseAsset
// handler enforces COMPLIANCE-BEFORE-CUSTODY ordering (A-544): checks
// IsCompliant(partnerID) via the shim BEFORE the custody debit. The
// compliance status is derived from MsgRecordComplianceAttestation
// records (the attestation-ref against a partner). A non-compliant
// partner REJECTS the release (the asset stays in custody).
//
// Both dependencies are expressed as INTERFACES defined HERE (in
// x/hub/types), NOT as struct imports of x/partner/types. The concrete
