Lead decisions

• confirmed· blockfrostprotocol-parameters

  The transaction builder reads Blockfrost's latest epoch parameters.

  • src/modules/txbuilder/index.ts:28"/epochs/latest/parameters"

• confirmed· kupoblock-encodingera-identitytransaction-encoding

  The indexer tools query Kupo matches. Kupo cannot index Dijkstra blocks (R2 gap), so its matches stop at the fork.

  • src/lib/kupo.ts:24return kupoFetch<KupoMatch[]>(`/matches/${encodeURIComponent(pattern)}`);

• not-reached· blockfrostera-identity

  No shipped tool calls /network/eras.

  • src/modules/txbuilder/index.ts:28"/epochs/latest/parameters"

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

  Only the bundled demo app imports CSL; the MCP server does not.

  • demo-app/server.ts:972const csl = await import("@emurgo/cardano-serialization-lib-nodejs");

• not-reached· koiosera-identityprotocol-parameters

  Shipped tools read no Koios era fields or epoch parameters; parameters come from Blockfrost.

  • src/modules/txbuilder/index.ts:28"/epochs/latest/parameters"

• not-reached· meshjs-mesh-sdkplutus-languageprotocol-parametersstake-pool-registrationtransaction-encoding

  Builds and submits its own Conway-shaped transactions; nothing Dijkstra-only is decoded.

  • package.json:20"@meshsdk/core": "^1.7.0",

• not-reached· maestro (deprecated)era-identityprotocol-parameterstransaction-encoding

  Defines Maestro base URLs and a Maestro client, but no shipped module imports or calls the client.

  • src/lib/maestro.ts:39export async function maestro<T>(
