The CI node binary cache was rebuilt on Aug 14 against latest polkadot-sdk master, which broke two integration tests for every PR (both failures also reproduce on master's daily compatibility run):
decode_transaction_extensions_from_blocks: the kitchensink runtime gained a newAsScarcitytransaction extension (pallet-scarcity: coinage-style NFT ownership with feeless rest-time-prioritized transfers polkadot-sdk#12730), so 13 extensions are now advertised vs the 12 hardcoded in the test.storage_iter:System.Accountnow has 17 genesis entries rather than 19.Notably, the first failure is a live example of what #2265 / #2273 addresses: a runtime adding a transaction extension breaks a client with hardcoded knowledge of the extension set.
Also includes a
cargo fmtfix for two test asserts intransaction_extensions.rswhich landed unformatted on master and fail the fmt check for every PR.
