• fail txtop and cardano-node-api before and after the gouroboros upgrade · 86a013e pinned (gouroboros 0.208.5)
• pass txtop and cardano-node-api before and after the gouroboros upgrade · 86a013e with gouroboros v0.213.0 · Connects and shows mempool sizes; mempool decoding is the tx-era-detection check.

Lead decisions

• confirmed· gouroborosera-identity

  Decodes every mempool transaction through gouroboros ledger types that predate the Dijkstra transaction format.

  • main.go:1262ltx, err := ledger.NewTransactionFromCbor(txType, raw)

• not-reached· gouroborosblock-encoding

  txtop imports only the gouroboros root, ledger and ledger/common packages and uses LocalTxMonitor; it reads no blocks or protocol parameters and applies no ledger or consensus rules.
