v0.1.0

EchoSVM v0.1.0

EchoSVM v0.1.0 turns bytecode compatibility into an executable, versioned
contract and adds a deliberately bounded Solana syscall surface for standalone
program inspection.

Included

• echosvm conformance runs 106 deterministic vectors across ALU32/64,
  JMP32/64, memory operations, verifier rejection, runtime faults, and sBPF
  version gates. JSON output follows echosvm.conformance.v1.
• echosvm compare <reference> <candidate> checks semantic execution fields
  and classifies results as match, known-difference, or regression using
  echosvm.compat.v1.
• --runtime solana-minimal exposes five explicit syscall families:
  sol_log_64_, memcpy, memmove, memcmp, and memset.
• Standalone results record their runtime profile, syscall arguments/results,
  and emitted logs.
• Transaction fixtures accept either one instruction or a non-empty
  instructions array for multi-instruction failures.
• Transaction bytecode traces carry invocation ordinals, improving evidence
  mapping when the same program executes more than once.

Honest boundary

solana-minimal is not the Agave runtime and does not provide CPI, PDA,
cryptographic, sysvar, allocator, or account-serialization syscalls. Programs
requiring full transaction semantics should use explain-run, which remains
LiteSVM/Agave-backed. The 106-vector report proves only its named instruction
families and version gates. V4 remains experimental; validator equivalence and
historical Mainnet replay are not claimed.
