State roots disagreeThis replay was checked against the effects the block published, and it reproduced 12 of 12 of them. It was NOT checked against the block's state-tree roots, and none of the 4 roots the capture recorded agree with the chain's: noteHashTree, nullifierTree, publicDataTree, l1ToL2MessageTree. Replay hydrates only the leaves this execution touched, so the trees it rebuilds are sparse and their roots cannot equal a full block's — the surprising outcome would be a match. What that costs is narrow and worth stating: this recording is evidence about the execution, and not a proof of the block's resulting state.
Narrow session: Code, Call Trace and Values only, read-only. The event log and stepping need a wider viewport.
  • CODE
The session is stopped at step 0 of 169

No source resolved for the code this transaction ran, so this recording is at instruction level: every step is a program counter into the contract's bytecode. A chain publishes the bytecode that ran and not the source it was built from, so source has to be obtained separately and proved against that bytecode — which has not happened for this contract. Stepping is complete either way.

169 recorded steps, 0–168 as the session counts them · program counter · opcode · L2 gas since the previous step — counters are offsets into /aztec/0x0843f42e2d1624f2b0566c73e16a88265e645a7957282ce228b91bd20b07f9cf.avm

2 recorded entries — every call this recording opened, in the order it opened them, and 0 storage writes. Each row's step is its coordinate in the recording. The replay's reproduced effects are published as a count rather than one record each, so they are in the transaction pane and not in this timeline.

The rows below are the AVM's own machine columns at this step, read from the recording. They are not program variables. This recording carries no variable names. Naming a local needs the debug symbols from the contract's compiled artifact, and none resolved for this contract.

BlockTracer holds no call data for this transaction, so there is nothing here for an ABI to decode. Whether none was published or the body was pruned before it was captured is not something this section can tell; where that is known, it is stated above.

An Aztec node serves neither: getContractClass returns ContractClassPublic, which is exactly { id, privateFunctionsRoot, version, artifactHash, packedBytecode } — no debug symbols, no file map, no function table, no source. Upstream's own doc comment on artifactHash says it is \"intended to be used by clients to verify that an OFFCHAIN FETCHED ARTIFACT matches a registered class\", i.e. the chain holds a commitment to the artifact and not the artifact. No method on AztecNode serves one either. THAT OFF-CHAIN RESOLUTION IS BUILT (replay/src/artifact_resolution.ts) AND IT WAS RUN FOR THIS CONTRACT AND PROVED NOTHING: no candidate artifact matched this class's artifactHash, its packedBytecode and its class id, so there is no debug map to position a program counter with and the rung is 3.
