keyfunc --version printed dev for any binary not built with make build. When no version was stamped at build time, the tool now reports the module version recorded in the binary's build info, which go install fills in. A stamped version still wins, and a local build with neither still prints dev.
Model: opus-4-8 (implementation); fable-5-1 (summary)
ssh install no longer runs a command on the host. It reads .ssh/authorized_keys over sftp, takes the empty reading only from sftp's own message about that path, appends the derived key locally when it is not already present, uploads the result beside the file with mode 0600 and renames it over the original. Any other failure prints what sftp said, writes nothing and exits 1. sftp batch mode disables password prompts, so a key or agent is required; a directory the owner cannot enter reads as a host with no file, which README.md states.

The README is the specification sneak approved on 2026-09-07, moved
here from the hacks repository: deterministic SSH keys, age identities
with encrypt and decrypt, and child mnemonics, all derived from one
BIP-39 mnemonic and stored nowhere.
