Commands that change the vault hold an exclusive lock on DIR/.lock and
readers hold a shared one, taken after the passphrase prompt. A blocked
process says it is waiting. Unix uses fcntl locks and Windows uses
LockFileEx, both released by the OS if the process dies. Plan 9 and
WebAssembly fall back to an exclusive lock file.
build.sh cross-compiles static binaries for every Go target that builds
without cgo (43 today, armv6 and armv7 for 32-bit ARM Linux) and writes
SHA256SUMS.
Strip Fury back to its vault functionality in one `vault` command:
genkey, init, add (file or directory, optional folder inside the vault),
list, get, mv and rm.
The hybrid FrodoKEM-640 + ML-KEM-768 encryption core is kept under
internal/pqcrypt. Signing, policies, profiles, backups, SSH remotes,
FIDO2, agents, provenance and compression are removed.
