Lead decisions

  • confirmed· blockfrostprotocol-parameters

    The Blockfrost chain context reads latest epoch parameters.

  • confirmed· kupoblock-encodingera-identitytransaction-encoding

    The Kupo-wrapped chain context reads UTxOs, datums and scripts from Kupo. Kupo cannot index Dijkstra blocks (R2 gap), so its matches stop at the fork.

  • confirmed· ogmiosprotocol-parameterstransaction-encodingera-identityplutus-language

    The Ogmios v5 and v6 chain contexts read parameters, submit and evaluate through Ogmios.

  • not-reached· blockfrostera-identity

    Network timing comes from /genesis, not /network/eras.

  • not-reached· ogmiosblock-encoding

    The chain contexts follow no chain.

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

artifact

PyCardano tag v0.19.2 and root manifest 0.19.2 agree; native Poetry verifies the root lock content hash. All 95 lock entries and their main/dev/docs groups, extras, markers and candidate distribution hashes remain retained. Package occurrences are separated by locked group. This does not verify a published wheel/sdist or installed Python environment; example/full-stack and Haskell integration-test projects are outside this production root.

Next: Verify the published Python distribution provenance and collect an installed inventory for an explicitly selected Python/platform/extra configuration.

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

Poetry captures library dependency selections, not the build-backend closure or installed native cryptography/serialization libraries. Candidate wheel/sdist hashes do not identify the installed artifact; marker and optional activation remain conditional.

Next: Capture build-backend and native library dependencies plus the selected wheel/sdist artifacts without treating all lock candidates as simultaneously installed.

profile:pycardano:bb6954c174a05503413c3078

resolution

Poetry lock retains all packages, groups, markers, extras and candidate distribution hashes. Target Python/platform and extra activation are not evaluated; installed wheel/sdist selection, build-backend dependencies, native libraries and published artifact correspondence remain unverified.

Next: Recollect a complete native build plan for this profile.

profile:pycardano:bb6954c174a05503413c3078

artifact

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

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

integration

PyCardano source exposes Blockfrost, cardano-cli, Ogmios and Kupo backends. Its CBOR module defaults to cbor2pure and switches to cbor2 when CBOR_C_EXTENSION=1. The chosen backend, endpoint/network, node or service version and CBOR environment are unverified consumer configuration, not capability or hardfork findings.

Next: Capture the production chain context and CBOR environment, identify service/native versions, then manually review transaction/serialization/query/submission behavior.
