Subject: [PATCH 01/16] chore: bump the SDK to 31.0.0-beta.7 and drop chain v7
 support

The SDK narrowed SUPPORTED_SPEC_VERSION_RANGE to 8.x in 31.0.0-beta.1 and
throws when connecting to a v7 node, so the suite is now v8 only and every
v7 branch in it is unreachable. These changes have to land together: the
bump does not compile until the removed APIs are gone, and the v7 gates
cannot be dropped before the bump makes them dead.

context.isV7 no longer exists, so isChainV7 silently returned undefined and
quietly disabled the code it guarded. Remove it along with the branches it
fed. withPendingInstructionBlock now shares getPendingInstructionEndBlock
rather than keeping a v7 escape hatch, and that helper always resolves a
block, so its return type loses the undefined.

The ChildIdentity entity and every child identity API were removed from the
SDK, so their example and (already skipped) suite go with them.

Two suites were gated to v7 only and now run on v8:

- The off chain settlement leg of tradeAssets. 30.1.1-beta.3 corrected the
  v8 receipt expiry and encoding, which is what kept it on v7.
- createSto. The on chain funded parts pass on v8. Its off chain funding
  section is extracted into enableOffChainFunding and
  investWithOffChainFunding, and the invest is pinned as a known SDK defect:
  the chain's FundraiserReceiptDetails carries an expiresAt that
  offChainFundingReceiptDetailsToMeshReceiptDetails never sets, so it
  encodes as 0 and every off chain funded investment is rejected with
  sto.ReceiptExpired. generateOffChainFundingReceipt has no parameter to
  supply one either. The equivalent fix landed for settlement receipts in
  30.1.1-beta.3 but not for STO funding receipts.

relayer.removePayingKey was the v7 spelling of relayer.removeSubsidy, so the
subsidy suite asserts the v8 tag directly.

 ## Notes
 
 - EVM tooling is only expected on chain v8+ presets.
+- The suite requires a **chain v8 preset** (`envs/8.0`, `envs/latest`). The Polymesh SDK dropped v7
+  support in v31 and throws on connecting to a v7 node, so `envs/7.2` can no longer be used here.

Subject: [PATCH 02/16] fix: align the staking tests with the v8 bonding model

BondPolyxParams.controller and SetStakingControllerParams were removed in
31.0.0-beta.1, and Staking.setController is now a no args procedure: a stash
can only make itself its own controller.

A stash is already bonded as its own controller on v8, so setController
rejects with staking.AlreadyPaired. Assert that rather than a success, since
the call only has an effect for legacy stashes that still have a separate
controller. The separate controller account the suite used to bond through
is gone; the stash signs bondExtra, unbond and withdraw itself.

The remaining tests were gated to v7 and never ran on v8. They pass once
they sign as the stash, so drop the gates.

Also cover two behaviours the bump changed:

- staking.getPayee returns null for an Account that has never bonded rather
  than throwing (31.0.0-beta.1).
- Bonded POLYX shows up in the new reserved field on the Account balance
  (30.1.1-beta.2).

Covers Assets.getTickerRegistrationConfig and the ticker length validation

maxTickerLength is now rejected by reserveTicker and createAsset before
submission, and one exactly at the limit is accepted.

Subject: [PATCH 07/16] test: add coverage for the rebuilt transaction groups

31.0.0-beta.1 and beta.2 rebuilt the transaction groups from the chain's own
permission model, which changes what a permission UI built from
TX_GROUP_TO_TAGS_MAP produces.

Pins the mapping so a regression in the constants is caught without a chain
round trip: RelayerManagement is gone, DidRegistration and
InstructionMediation are new, MultiSigManagement is down to the one
permission checked call, tags for extrinsics no longer on chain are absent,
and nft.CreateNftCollection is reachable through an agent grantable group.

Then grants the two new groups to a secondary key end to end, since they are
newly grantable rather than relocated and no existing grant covers them.

Subject: [PATCH 08/16] test: add coverage for portfolio level asset
 pre-approval

30.2.0-beta.4 added pre-approval at the Portfolio level alongside the
existing Identity level one, alongside Portfolio.preApprovedAssets.

Covers preApproveAsset, isAssetPreApproved, preApprovedAssets and
removeAssetPreApproval, and asserts the two levels stay independent:
removing the Identity approval leaves the Portfolio one in place.

Subject: [PATCH 09/16] test: add coverage for registrar gated DID registration

30.2.0-beta.5 added the registerDid procedure and 31.0.0-beta.1 renamed
Identity.isCddProvider to isDidRegistrar, deprecated registerIdentity and
reduced issuing a CDD claim to the DID Registrar role.

Covers the happy path signed by a registrar, the rejections for an Account
that already has an Identity and for a signer without the role, and both
sides of the CDD claim role check.

Subject: [PATCH 10/16] test: add coverage for the realigned transfer errors

31.0.0-beta.1 aligned TransferError with the errors the chain actually
reports, removed the TransferStatus enum, dropped the CDD and investor
uniqueness members, and added InvalidReceiverIdentity. canTransfer reports
failures in its breakdown rather than throwing.

Pins the enum membership and covers the breakdown for a valid transfer, an
insufficient balance and frozen transfers.

Two cases are asserted as they actually behave rather than as the names
suggest. A transfer within one Identity is not a SelfTransfer on v8, since
an Identity may move funds between its own holders. And a decimal amount for
an indivisible Asset never reaches the chain to produce InvalidGranularity,
because the SDK rejects it while encoding the call.

Subject: [PATCH 11/16] test: add coverage for the transferFunds instruction
 result

31.0.0-beta.5 changed Assets.transferFunds from void to
Instruction | undefined and allowed transfers between asset holders on
different Identities.

Covers all three outcomes the return type encodes: undefined when the
transfer settles immediately within one Identity, undefined when it settles
immediately because the receiver auto affirms or has pre-approved the asset,
and a resolved pending Instruction when the receiver has opted in to
mandatory affirmation and has yet to affirm.

Also covers the NFT leg, reworked in beta.5 and beta.7.

Subject: [PATCH 12/16] test: add coverage for the mediator lock and unlock
 cycle

30.2.0-beta.2 added unlockInstruction, completing the lock/relock cycle for
a SettleAfterLock instruction, and 30.2.0-beta.3 added getters for leg status
and venue signer count.

Walks the cycle as a mediator: lock for execution, read the lock info, read
each leg's status, unlock back to pending, and read the relock cooldown the
unlock starts. Then asserts a relock inside that cooldown is refused, which
happens while the transaction is prepared rather than on submission.

A receiver that has not opted in to mandatory affirmation is affirmed when
the instruction is created, so the helper only affirms the receiving side
when it is still pending.

Venue.getSignerCount is asserted against getAllowedSigners in createVenue,
where the off chain suites already exercise a venue with signers.

Subject: [PATCH 13/16] test: add coverage for the aggregated next checkpoint
 getter

Covers Checkpoints.Schedules.getNextCheckpoint, added in 31.0.0-beta.3. With
one active Schedule the aggregate should agree with that Schedule's own
details, so the example asserts the date, the pending total and the Schedule
attribution against it.

The documented null case is split in two because only one half holds. An
Asset that never had a Schedule reports null. An Asset whose Schedules have
all been removed throws, and is pinned as a known SDK defect: the chain keeps
cachedNextCheckpoints populated with a nextAt sentinel of u64::MAX, which
momentToDate cannot convert.

Subject: [PATCH 15/16] fix: bump the SDK to 31.0.0-beta.8 and flip the two
 pinned defects

31.0.0-beta.8 fixes both SDK defects that were pinned as known-broken while
the suite was on beta.7:

- getNextCheckpoint now returns null once every Schedule has been removed,
  instead of throwing on the chain's u64::MAX nextAt sentinel. The
  checkpoint test asserts the documented null behaviour directly.
- offChainFundingReceiptDetailsToMeshReceiptDetails now encodes expiresAt,
  so an off chain funded STO investment settles instead of being rejected
  as sto.ReceiptExpired. createSto asserts the investment succeeds instead
  of asserting it fails.

This release also makes expiresAt required (previously optional) on
generateOffChainAffirmationReceipt/generateOffChainFundingReceipt and their
receipt types, part of the same fix. Both call sites in this suite already
passed it, so no other change was needed.

Subject: [PATCH 16/16] chore: move off the beta tag to the stable SDK 31.0.0
 release

31.0.0 is now published to the latest dist-tag with the same content as
31.0.0-beta.8 (its changelog is the squashed history of every 31.0.0-beta.*
commit plus the beta.8 fix), so no other change is needed.
