Observe-only monitor for Axelar express-execution reimbursement via the Axelarscan GMP API. Two modes: scan recent express transfers per chain, or watch a single source tx through both phases (express-executed → executor reimbursed). Adds the CLI subcommand, the test_express module (gmp_api + types + orchestrator), a workflow-dispatch CI workflow, and AXE_STATE docs. v1 is monitor-only; originating a qualifying express transfer is a follow-up.
…med-out txs Before marking a non-Done tx failed at the inactivity timeout, query the Axelarscan GMP API once; if the message executed on-chain, reclassify it as successful and flag recovered_via_api. Best-effort and non-fatal (15s bound). Promote the searchGMP client + ExpressRecord to a shared crate::gmp_api module and reuse it from load_test and test_express.
… across finality tiers
Phase 2 now decodes the executor EOA's outbound ERC-20 Transfer in the express tx (fronted) and its inbound Transfer in the execute tx (reimbursed) from the GMP-API receipt logs, and asserts they are equal. Mismatch or missing inbound is surfaced as an error and fails the single-tx watch; fronted/reimbursed base-unit amounts are printed in both modes. Closes the MOU-26 manual-check gap (MOU-27).
The poll path's EVM gateway checks (isMessageApproved / isMessageExecuted / isCommandExecuted) called .call().await? directly. A single transient RPC blip (5xx / 429 / dropped connection) in any poll cycle propagated up through poll_pipeline and aborted the whole verification run, marking every in-flight tx failed. The cosmos LCD, Sui, Solana and XRPL paths already have fallback/retry; EVM (the dominant mainnet destination class) did not. Wrap all three read-only, idempotent view-calls in retry_all (3 attempts, geometric backoff) — the exact use case the retry module documents for alloy provider calls.
…rors The load-test verifier polls is_message_approved / is_message_executed on the Stellar gateway through simulate_view, which called simulate_transaction_envelope with no retry. A transient Stellar RPC hiccup (connection reset / 5xx) in any poll cycle aborted the whole verification run — observed live on a mainnet hyperliquid->stellar route that had already executed on-chain (the message was delivered, but the verifier crashed on a connection reset at rpc.rs:746). Wrap the read-only simulation in retry_all (3 attempts, geometric backoff), mirroring the EVM destination view-call retry and the existing XRPL account_info retry. Same bug class as the EVM fix, now closed for Stellar too.
