What fixing it unlocks

Step 5 of the fix order: once the earlier steps land, it unlocks 8 more tools: apollo, cardano-mcp, cardano-web3-js, chrysalis, dandelion-apis, dexter, midgard, yaci-devkit.

If only this were fixed

No tool on its own: every tool that needs it also waits on something else.

Lead decisions

  • confirmed· ogmiosblock-encodingera-identitytransaction-encoding

    Kupo can follow the chain through Ogmios chain-sync instead of a node socket.

  • confirmed· ouroboros-consensusblock-encodingera-identity

    The consensus pin fixes an earlier ledger whose Dijkstra block body and header differ from the target (R2: cardano-ledger-dijkstra 0.2.0.1).

  • not-reached· ogmiosplutus-languageprotocol-parameters

    Through Ogmios Kupo only follows blocks and reads the genesis configuration; it submits, evaluates and queries no parameters.

  • not-reached· ouroboros-consensusnode-to-client-protocol

    ouroboros-consensus 3.0.1 (node 10.7.1/11.0.1) already offers node-to-client V23.

Dependency profiles

No native profile has been collected. Dependency coverage is unresolved, not empty.

Chain-facing capabilities

Findings describe behavior in a specific release and configuration. Suggestions need verification; historical findings do not establish behavior in the current source. None establishes hardfork compatibility.

No capability findings have been returned. Behavior remains unresolved; an empty list does not mean this tool has no chain-facing capabilities.

Unresolved frontiers and next actions

capability

Chain-facing capabilities have not been reviewed.

Next: Review production entry points and integration behavior.

integration

Runtime, bundled, and service dependencies have not been reviewed.

Next: Export a discovery review packet.

resolution

No native dependency resolution has been imported.

Next: Collect a native resolution for a declared release/profile.

artifact

Source release identified; published package/binary correspondence and supported profiles need verification.

Next: Confirm distribution artifacts and production configuration with release evidence.
