Motivation

The orchestrator contract address was stored as a single scalar ([orchestrator].address) shared across all networks. As the system expands to multiple chains (Base, Ethereum, HyperEVM), each chain carries its own orchestrator deployment at its own address. A single address cannot serve multiple networks, and silently routing all chains to one address would be a correctness error.

Solution

The [orchestrator].address scalar is replaced by an [orchestrator.addresses] map keyed by network wire name (base, ethereum, hyperevm). The old key is rejected at parse time via deny_unknown_fields, so a config that still carries address = "0x…" fails loudly rather than silently dropping the address.

VaultModeConfig is restructured to separate the mode kind (symbol-keyed, network-agnostic) from the orchestrator address (network-keyed). VaultModeKind replaces the address-carrying VaultMode variants in the per-asset and default maps; mode_for now takes a Network argument and joins the kind with the network's address at query time, returning a typed MissingOrchestratorAddress error rather than silently falling back to vault-direct. A new kind_for method handles the cases (status surfaces, vault-mode tag) where only the kind is needed and no network is available.

At startup, Env::into_config enforces that when any asset resolves to orchestrator kind, every configured chain has an [orchestrator.addresses] entry — a missing entry is a deploy error, not a runtime surprise at mint or redemption initiation time. Unknown network keys and zero or malformed addresses remain startup errors.

All call sites that previously passed a VaultMode now pass a VaultModeKind plus a separate address map, and the two mint/burn anchoring points (initiate_mint, detect_transfer) resolve the full VaultMode (kind + network address) at anchor time, preserving the existing guarantee that a mid-flight mode change does not affect in-progress operations.

A new integration test (tests/multichain_orchestrator.rs) runs two Anvil chains with orchestrators at deliberately different addresses, executes one orchestrator-mode mint per chain, and asserts that each mint's Minted log appears on exactly its own chain's orchestrator and nowhere else.

Closes RAI-1749

Review Change Stack

Walkthrough

The configuration changes replace one global orchestrator address with validated per-network addresses. Runtime mode resolution, minting, redemption, health checks, CLI workflows, onboarding documentation, and multichain integration tests now use the selected network.

Changes

Multichain orchestrator routing

Layer / File(s) Summary
Network address configuration and validation
src/config.rs, config.example.toml, config.prod.toml, config.staging.toml
VaultModeConfig stores mode kinds separately from network addresses. TOML parsing validates known networks, non-zero addresses, complete chain coverage, and removal of the retired single-address format.
Network-aware runtime mode resolution
src/admin.rs, src/mint/..., src/redemption/transfer.rs, src/tokenized_asset/api.rs, src/lib.rs, tests/harness/mod.rs
Runtime paths resolve concrete vault modes with an asset network. Missing orchestrator addresses propagate through mint and transfer errors. Status responses expose only the network-independent mode kind.
Network-specific CLI and onboarding flows
src/tokenized_asset/cli.rs, docs/runbooks/orchestrator-onboarding.md, SPEC.md
Preflight, approval, signing verification, receipt migration, and onboarding commands resolve addresses from the selected network. Explicit receipt-migration destinations remain available for wallet rotation.
Multichain routing integration coverage
tests/multichain_orchestrator.rs
The integration test uses separate Base and Ethereum orchestrators and verifies network-specific authorization, mint completion, redemption, credited shares, and chain-specific events.

12-14: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Make the runbook network-parameterized.

The opening states that every step runs on Base mainnet. The same document later requires a cutover on every listed chain. The fixed --network base --chain-id 8453 examples can make an Ethereum or HyperEVM operator run a valid command against the wrong configured orchestrator.

Use <network> and its canonical <chain-id> in the generic procedure. Mark Base values as RKLB pilot examples only.

Based on the PR objective, this cohort adds “Network-specific CLI and onboarding flows.”

Use enum-based, query-oriented states for views; do not wrap view data in confusing nested Options when GenericQuery::load already returns Option.

Use structured tracing fields such as info!(key = %value, "message"), not interpolated values in log messages.

Learning: In Rust recovery loops or similar retry patterns,INFO/WARN log statements that are immediately followed by return; or break; inside the loop body are acceptable because the loop runs at most once for the exit path and won't flood logs. The existing guideline about DEBUG/TRACE logs per iteration applies to repeated logging inside loops; use INFO or WARN for exit paths and avoid per-iteration DEBUG/TRACE logs in retry loops. When reviewing code, flag cases where a log level dominates per-iteration noise and suggest moving exit-logs outside the hot loop or gating by a condition, ensuring the log appears at non-repetitive times.

Learning: In Rust code, within loops that spawn long-running background tasks (e.g., tokio::spawn) such as detectors, monitors, or services, INFO logs inside the loop body are acceptable if the loop is bounded and each iteration launches a persistent background worker. This acknowledges a significant operational event per iteration without causing excessive log noise. Apply this guidance when the loop has a clear exit condition and the spawned task persists beyond the iteration. If the loop is unbounded or spawns short-lived tasks, prefer lower log levels or structured tracing to avoid log flooding.

Learning: In Rust error enums, follow the AGENTS.md constraint that variant names “must be generic when using #[from]” only for enum variants annotated with #[from] (i.e., variants that derive the `From` conversion for the wrapped error type). For variants populated via manual error construction/handling (e.g., created in code paths using `.map_err(...)`), the naming constraint does not apply—use descriptive or categorical variant names to group related failure reasons (e.g., `HttpClient(Box<dyn Error + Send + Sync>)`).

Learning: In test files under tests/**/*.rs, crate-level lint suppression #![allow(clippy::unwrap_used)] is acceptable only when explicitly permitted by the user. E2E tests may benefit from using .unwrap() for immediate panic-on-failure feedback showing the actual value. Apply this guideline only to tests and ensure suppression is clearly documented and restricted to cases approved by the user, avoiding blanket suppression in non-test code.

Learning: In the ST0x-Technology/st0x.issuance repository, markdown files should not be linted for formatting issues. Do not suggest or enforce Markdown linting rules (e.g., MD040) or cosmetic markdown fixes in docs/*.md files; treat Markdown formatting as outside the review scope for this repo.

Learning: Applies to src/**/*.rs : Public APIs must use /// documentation comments; ordinary comments should explain rationale, complex logic, external behavior, constraints, or workarounds rather than restating code.

Learning: In `src/lib.rs` and `src/config.rs` for `st0x.issuance`, treat `Config::receipt_poll_interval` as hardcoded from the `RECEIPT_POLL_INTERVAL` constant (60s) set in `Env::into_config`, with no env/CLI override. As long as it remains hardcoded (so `0` is unreachable on production paths), do not flag `tokio::time::interval(config.receipt_poll_interval)` in `spawn_periodic_receipt_backfills` as a potential panic risk. It’s acceptable for tests or external callers to construct `Config` with `receipt_poll_interval = 0` and trigger a panic (use that panic as test feedback). Also, do not introduce a runtime `Config::validate()` method; follow the project rule in `AGENTS.md` (“Parse, Don't Validate”).
