Lead decisions

• confirmed· koiosprotocol-parameters

  Live protocol parameters are taken from Koios /epoch_params as the source of truth.

  • src/api/liveProtocolParams.ts:4* Source of truth: Koios epoch_params (no project_id). Cached in protocol_params.

• not-reached· blockfrostera-identityprotocol-parameters

  Gerolamo serves its own Mini-Blockfrost API; the dashboard reads that, and only a verification script calls an external Blockfrost.

  • dashboard/src/lib/explorer.ts:2* Explorer client for the node's Mini-Blockfrost API (/api/v0). Types mirror

• not-reached· buildooorplutus-languagetransaction-encoding

  buildooor is declared in package.json but no shipped module imports it.

  • package.json:33"@harmoniclabs/buildooor": "^0.1.31",

• not-reached· cardano-db-syncblock-encodingera-identityprotocol-parametersstake-pool-registrationtransaction-encoding

  db-sync mentions explain reward accounting in a Koios comparison script. The script fetches Koios HTTP endpoints, not db-sync; the Koios link is assessed separately.

  • scripts/ledger-koios-check.ts:42const base = net === "mainnet" ? "https://api.koios.rest/api/v1" : `https://${net}.koios.rest/api/v1`;

• not-reached· cardano-serialization-lib-cslplutus-languageblock-encodingprotocol-parametersstake-pool-registrationtransaction-encoding

  CSL comes in through @blockfrost/blockfrost-js, which uses it for address derivation helpers.

  • bun.lock:62"@blockfrost/blockfrost-js": ["@blockfrost/blockfrost-js@

• not-reached· koiosera-identity

  Gerolamo reads no Koios era names.

  • src/api/liveProtocolParams.ts:4* Source of truth: Koios epoch_params (no project_id). Cached in protocol_params.

• not-reached· mithrilblock-encoding

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

  • flake.nix:42inputs.mithril.packages.${system}.mithril-client-cli

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

  These matches describe the Ogmios-compatible additionalUtxoSet input accepted by Gerolamo's own Blockfrost server. The code parses that input and evaluates locally; it does not call Ogmios.

  • src/api/blockfrost/routes/txs.ts:256const r = evaluatePhase2Sync(

• not-reached· ouroboros-miniprotocols-tsnode-to-client-protocol

  Gerolamo now explicitly offers node-to-client versions 16 through 23 in its own responder. The previous V16-V19-only finding is cleared by the refreshed source; this does not establish support for every V23 query.

  • src/network/n2c/HandshakeResponder.ts:17export const GEROLAMO_N2C_VERSIONS: readonly VersionNumber[] = [16, 17, 18, 19, 20, 21, 22, 23];

• not-reached· pallasblock-encodingera-identity

  Pallas is in the standalone reference evaluator under tools/uplc-ref. It explicitly decodes Conway transaction/input/output primitives; it does not follow blocks or infer multi-era identities on the shipped node path.

  • tools/uplc-ref/src/main.rs:8use pallas_primitives::conway::{
