How far back this chain can be debugged

Stepping a transaction means re-executing it, and that needs the state the chain was in just before it ran. On this chain it is kept for a moving window and was obtainable at block 69336 and above when this generation was captured. THAT IS A LIMIT ON WHAT CAN BE RECORDED, not on what is published here. A transaction already recorded carries its own execution and steps from it for good; the boundary says that a transaction below it cannot be recorded NOW by the pipeline that records this chain. Why it cannot is that pipeline's finding and not this page's: the sentence below is its own record of what it measured. And the boundary MOVES UP as the chain advances, so what can be recorded shrinks from below while what is already published does not.

This chain's published data carries no count of debug tiers, so this page states none. Each transaction's own page states whether it steps at source level or instruction by instruction.

How that boundary was established, in the pipeline's own words: “prestate was obtainable from 69336 upward when this generation was captured, and not below it”

Recordings on this chain are executed from the aztec-avm format. Each transaction's page states the granularity its steps are reported at: source lines where the contract's source was resolved, otherwise the format's own units.
