The slice landed one commit too early: the vault links
tdesktop::lib_argon2 and the build recipe for it was written, but the
recipe was invisible — the bare "cmake" .gitignore pattern struck a
second time on lib_argon2.cmake — and ThirdParty/argon2 itself never
existed, so origin/dev stopped at configure with a missing include.
The reference implementation comes in as a submodule pinned to the
20190702 release, whose layout is exactly what the recipe lists.
The tail of the work rides along: a file-backed chunk store, and a
security floor for new vaults — creation now demands at least 64 MiB
and three passes from the Argon2id config instead of accepting
anything structurally valid, with the vault test pinning that
boundary.
