Migrate existing TIBCMT class traces before changing the store key.
SendMtTransfer resolves existing tibc-<hash> classes with ClassPathFromHash. That method reads the class trace from the keeper store and returns ErrTraceNotFound when the record is absent. Existing traces remain under tibcnfttypes.StoreKey, but the new keeper reads tibcmttypes.StoreKey. Therefore, sending an existing voucher whose trace predates this change can fail.
Add a migration that copies the class-trace records, or retain the old key until the migration runs.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick winReset capability state with the reset IBC channel state.
The recovery genesis replaces IBC with default state, which starts channel allocation at
channel-0, but it retains exported capability entries. DuringChanOpenInit, IBC creates the capability forports/<port>/channels/channel-0. If that path existed before recovery,NewCapabilityreturnsErrCapabilityTaken, and the handshake fails.Add
capabilityto both module-exclusion lists. The retained TIBC keeper does not consume the capability scope, so this reset is independent of the transfer/NFT asset-state correction.Suggested fix

Swap the staking and distribution validator state of a target genesis (e.g. a mainnet export whose validator keys are unavailable) with the validators from a source genesis under the operator's own control, keeping the remaining target data intact so exported states can be exercised locally. Supports exported and collected-gentx source genesis, rejects targets with live tokenize-share records, and adapts pool/balances/supply so the merged genesis passes InitGenesis.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Import slashing signing infos for exported source validators. Without them, the merged chain stops after genesis.
When the source has exported validators, the code sets sourceStaking.Exported = true. It then keeps the target slashing module state unchanged (Lines 215-221). This combination breaks slashing:
- With
Exported = true, x/stakingInitGenesisloads the validator set fromlast_validator_powers. It does not call theAfterValidatorCreatedorAfterValidatorBondedhooks. - The x/slashing
AfterValidatorBondedhook is the code that creates a validator'sValidatorSigningInfo. So the source validators get no signing info. - The target slashing state only has signing infos for the removed target validators.
- In SDK v0.50,
HandleValidatorSignaturereturns an error whenGetValidatorSigningInfofinds no record. - The slashing
BeginBlockerpasses that error up, soFinalizeBlockfails.
The failure happens at the first block whose DecidedLastCommit has votes, which is the second block. The simulated chain then halts. TestGenesisReplaceValidatorsExportedSource only runs InitChain, so it does not catch this.
Gentx sources are not affected. Their validators go through the non-exported bond path, which runs the hooks.
Fix for exported sources:
- Require the source
slashingstate. - Replace
signing_infosandmissed_blocksin the merged state with the source values. - Keep the target slashing
params. - Update the
Longhelp text, which currently says slashing is kept from the target. - Extend the exported-source test to run
FinalizeBlockfor a block with a vote from the source validator.
