BREAKING CHANGES

• expiresAt is now required on
  Instruction.generateOffChainAffirmationReceipt and
  Offering.generateOffChainFundingReceipt, and on
  OffChainAffirmationReceipt and OffChainFundingReceipt.
• 🧨 Assets.transferFunds return type changed from
  void to Instruction | undefined. It resolves to the pending
  Instruction when a cross-DID transfer is left awaiting the
  receiver's affirmation, and undefined when the transfer settles
  immediately (same-DID, or the receiver auto-affirmed).
• 🧨 The following exported types are removed, along with the
  modifyCorporateActionsAgent procedure:

• ScopeClaimProof and AddInvestorUniquenessClaimParams — described
  identity.add_investor_uniqueness_claim, which does not exist on chain v8
• ModifyPrimaryIssuanceAgentParams — the Primary Issuance Agent concept was
  superseded by External Agents
• ModifyCorporateActionsAgentParams — its procedure's only caller,
  CorporateActions.setAgent, was removed in v22.0.0 in favour of
  Permissions.inviteAgent, but the procedure was left behind

None had any reference in the SDK and no procedure accepted or returned them.
There is no replacement because there is no longer an operation to describe.

testUtils Asset entity mocks no longer default a primaryIssuanceAgents
field, which AssetDetails has not had since v22.0.0.

• 🧨 - Removed the TransferStatus enum and its sole
  producer u8ToTransferStatus. TransferError — the enum actually
  populated, by Settlements.canTransfer — keeps its role, and its members'
  doc comments no longer refer to TransferStatus equivalents.

• Removed TransferError.InvalidReceiverPortfolio. Its sole producer was
  the granularCanTransferResultToTransferBreakdown cascade deleted with v7
  support, and it cannot be re-mapped: the portfolio pallet has a single
  PortfolioDoesNotExist variant, already mapped to InvalidSenderPortfolio.
• Added TransferError.InvalidReceiverIdentity for a receiving Identity
  that is not active. Both transfer-validation paths report this condition
  (nft.InvalidNFTTransferInvalidReceiverDID and
  asset.InvalidTransferInvalidReceiverDID) and neither was mapped, so it
  previously surfaced as a raw chain error name.
• Removed the transfersCanTransfer mock option in testUtils, typed
  against a return type canTransfer no longer has.
• See changelogs/v30.2.0-next.md for full
  migration guidance.

• 🧨 - Removed TransferError.InvalidReceiverCdd,
  TransferError.InvalidSenderCdd and TransferError.ScopeClaimMissing.
  The first two cannot be produced because transfers are no longer CDD
  gated; ScopeClaimMissing relates to Investor Uniqueness, removed from
  the chain some time ago.

• See changelogs/v30.2.0-next.md for full
  migration guidance.

• 🧨 - Removed TxGroup.RelayerManagement and
  RELAYER_MANAGEMENT_TX_TAGS. Every call in the relayer pallet is
  ensure_signed only, so the group never gated anything and no replacement
  grant is needed.

• TxGroup.MultiSigManagement / MULTISIG_MANAGEMENT_TX_TAGS reduced to
  multiSig.CreateMultisig, the only permission-checked call in the pallet.
  The rest are executed under the MultiSig's own origin via a proposal, are
  ensure_signed only, or are primary-key only. What a MultiSig may do via
  proposal is constrained by the permissions held by the MultiSig Account
  itself, not by its signers'.
• Added TxGroup.InstructionMediation / INSTRUCTION_MEDIATION_TX_TAGS
  (AffirmInstructionAsMediator, RejectInstructionAsMediator,
  LockInstruction, UnlockInstruction). These are newly grantable, not
  relocated — no group previously covered them, so existing
  SettlementManagement grantees do not already have them.
• Added TxGroup.DidRegistration / DID_REGISTRATION_TX_TAGS
  (identity.RegisterDid); TxGroup.CddRegistration is deprecated but
  retained.
• Removed tags for extrinsics no longer on chain:
  settlement.AddInstructionWithMemo, settlement.AddAndAffirmInstructionWithMemo,
  portfolio.MovePortfolioFundsV2.
• Added tags for permission-checked v8 extrinsics no group previously
  covered, across SettlementManagement, PortfolioManagement,
  StoManagement and CorporateActionsManagement.
• Consumers building permission UIs from TX_GROUP_TO_TAGS_MAP,
  AGENT_TX_GROUP_VALUES or the individual *_TX_TAGS constants should
  re-check their output.
• See changelogs/v30.2.0-next.md for full
  migration guidance.

• 🧨 - SDK now only supports chain v8 — connecting to a v7 chain throws on
  initialization (SUPPORTED_SPEC_VERSION_RANGE narrowed to '8.0').

• Removed: ChildIdentity entity and all child-identity APIs (Identities.createChild/
  createChildren/getChildIdentity, Identity.* equivalents), Claims.getCddClaims,
  Identity.hasValidCdd, RoleType.CddProvider/isCddProviderRole/CddProviderRole,
  AccountManagement.subsidizeAccount, consumeAddRelayerPayingKeyAuthorization/
  AuthorizationType.AddRelayerPayingKey, Instruction.withdraw/withdrawAsMediator/
  InstructionAffirmationOperation.Withdraw/WithdrawAsMediator, Nft.controllerTransfer's
  destinationPortfolio param, AcceptPrimaryKeyRotationParams.cddAuth,
  SetStakingControllerParams/BondPolyxParams.controller.
• Renamed: Identity.isCddProvider() → Identity.isDidRegistrar().
• Deprecated: Identities.registerIdentity (createCdd/expiry are now no-ops) —
  use registerDid/selfRegisterDid.
• Error message changes (update any string-matching code):
  'Beneficiary/Subsidizer Account does not have a valid CDD Claim' →
  '...does not have an associated Identity';
  'Issuing Identity does not have a valid CDD claim' → 'Issuing Identity does not exist';
  'Issuer must be a CDD provider' → 'Issuer must be a DID Registrar';
  'MultiSig signers must be accounts as of v7' → 'MultiSig signers must be accounts'.
