Both flags were uint32 flags, which the flag library reads with Go's
base-0 rules, so `-n 010` derived key 8 and `0x10` or `1_0` were
accepted. They are now string flags read by options.Decimal, which
takes decimal digits only: a leading zero stays decimal, and a base
prefix, an underscore or a sign is refused with an error naming the
flag, before the mnemonic is looked for. --help shows both as a
number, and the README says the index is a decimal number.
Model: opus-5-5
The module path becomes sneak.berlin/go/keyfunc, as the repo policy sets for Go modules: go.mod, every import and the -X path in the Makefile. The old path gets no alias. The README gives a go install line for the new path, which resolves with @latest only once main carries the move, and its TODO list now names the open 1.0 issues.
Model: opus-5-5
The module, the script entrypoints and Makefile, Docker-only linting, the mnemonic sources in the specified order with their refusals, the BIP-85 derivation, and keyfunc ssh pub and priv with the README test vectors as tests. Two review rounds; the second passed with no findings.
