The STRK fee token address that is deployed when initializing the default initial state used
by the virtual-OS flow tests and the apollo proof-flow integration tests. The resulting
address depends on the nonce of the deploying account — if extra init transactions are added
before the STRK fee token is deployed, the address must be updated. Run any failing test with
UPDATE_EXPECT=1 to refresh, then regenerate the proof fixtures by running
cargo +nightly-2025-07-14 test -p starknet_os_flow_tests --features starknet_transaction_prover/stwo_proving --release generate_proof_fixtures -- --ignored.
