What fixing it unlocks

Step 9 of the fix order: once the earlier steps land, it unlocks 4 more tools: adder, cardano-node-api, dingo, txtop.

If only this were fixed

cardano-node-api · then raise gouroboros@0.202.7<v0.213.0
dingo
txtop

Also needed by adder (still waits on kupo), bursa (still waits on ledgerjs-hw-app-cardano), cardano-ibc-incubator (still waits on kupo, ogmios, blockfrost, cardano-multiplatform-lib-cml)

Expand packages to follow dependencies. Shared artifacts can appear along several paths; cycles stop at the repeated occurrence. Complete native resolution does not mean complete tool coverage.

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.

artifact

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

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