Expand description
A minimal 65C816 disassembler for human-facing debug output.
Decode-only: disassemble_one takes a byte-peek closure (FnMut, so a caller may plug in
a real Bus::read24 when a side-effect-free peek accessor isn’t convenient) and does nothing
but decode the bytes it’s handed — it never touches CPU state and has no connection to
crate::exec, the real cycle-accurate interpreter, so a bug here can never affect emulation
correctness, only what a debugger prints. Prefer a genuinely read-only peek where one exists;
the closure type doesn’t enforce that, it only enables it. Built for the frontend’s debugger
overlay (docs/frontend.md §Debugger overlay) and for ad hoc instruction-level tracing (e.g.
docs/audit/’s boot investigations).
