dig-chainsource-interface 0.3.1

The DIG Network canonical ChainSource provider interface: the single pure trait + query types every Chia chain-source provider implements and every consumer depends on. Reads-only, no I/O, no keys, no network — chia-* deps only.

# dig-chainsource-interface — the DIG Network canonical ChainSource provider interface.
#
# The SINGLE pure trait + query types every Chia chain-source provider implements and every
# consumer depends on. There is ONE ChainSource contract for the whole ecosystem — never a
# per-crate copy that could byte-drift. This crate is a pure LEAF: trait + query/result types +
# a typed error + KATs + docs. It performs NO I/O, holds NO keys, opens NO network, and ships NO
# concrete provider — those live in the provider crates and in chia-query (the registry +
# aggregating canonical source). See SPEC.md for the normative contract.

# --- `lineage-walk` only (see [features]) ------------------------------------------------------
# The canonical launcher -> tip singleton walk DERIVES each successor by running the parent's inner
# puzzle, so it needs a CLVM evaluator and the vetted singleton layer/puzzle types. Every version is
# pinned to the same coherent chia-* set the rest of the DIG on-chain line rides (chia-protocol
# 0.36 / chia-wallet-sdk 0.34); the SDK's own SingletonLayer is reused rather than re-implemented so
# the walk cannot byte-drift from the puzzle it authenticates against.

# The canonical singleton lineage walk (`walk_singleton_lineage`). NON-DEFAULT: it pulls in a CLVM
