Lead decisions

• not-reached· aikenplutus-languageplutus-script-context

  Aiken's uplc crate is only in the lockfile; phase-two evaluation and script decoding use Amaru's own amaru-uplc crate.

  • crates/amaru-ledger/src/rules/transaction/phase_two/mod.rs:30use amaru_uplc::{
  • crates/amaru-ledger/src/rules/transaction/phase_one/outputs.rs:19use amaru_uplc::{arena::Arena, arena_pool::ArenaPool, flat::decode_plutus_script};

• not-reached· koiosera-identityprotocol-parameters

  Snapshot creation asks Koios only for the tip and block hashes, which carry no era name or protocol parameters.

  • crates/amaru/src/bin/amaru/cmd/snapshot/create/koios.rs:38.get(format!("{}/tip", koios_api_base(network)?))

• not-reached· mithrilblock-encoding

  Uses Mithril only to download certified snapshots for bootstrap; block decoding afterwards is the tool's own.

  • Cargo.toml:68mithril-client = { version = "0.14.17", default-features = false, features = ["fs", "num-integer-backend", "rustls-tls"] }

• not-reached· ogmiosblock-encodingera-identityplutus-languageprotocol-parameterstransaction-encoding

  Ogmios appears only in doc comments showing how era-history fixtures were captured; Amaru speaks the node protocols itself.

  • crates/amaru-kernel/src/cardano/era_history.rs:65/// curl -X POST "https://mainnet.koios.rest/api/v1/ogmios"

• not-reached· pallasnode-to-client-protocol

  Amaru uses pallas-network 0.34.0 only for a node-to-node peer client during bootstrap.

  • Cargo.toml:76pallas-network = "0.34.0"
  • crates/amaru-bootstrap/src/bootstrap/mod.rs:295PeerClient::connect(peer_address, network.to_network_magic().as_u64()).await.inspect_err(|err| {

• not-reached· pallasblock-encodingera-identity

  Amaru decodes the headers it fetches during bootstrap with its own Header type; pallas-network 0.34.0 only carries them.

  • crates/amaru-bootstrap/src/bootstrap/mod.rs:336from_cbor(&content.cbor)
  • Cargo.toml:76pallas-network = "0.34.0"
