Missing tipstream-multisig contract causes 3 test failures

[Mosas2000]

Problem

The test suite references a tipstream-multisig contract that does not exist in the project.

Affected Tests

• multisig signers can pause contract through governance
• multisig signers can change fee through governance
• execution fails without sufficient signatures

Error

Contract 'ST1PQHQKV0RJXZFY1DGX8MNSNYVE3VGZJSRTPGZGM.tipstream-multisig' does not exist

Solution Options

1. Create the missing tipstream-multisig contract
2. Skip/remove the tests if multisig feature is not ready
3. Add the contract to Clarinet.toml if it exists but isn't registered
