mhoennigandClaude Fable 5 2abde3aec9 Werkdock RFC 0001: implementation language evaluation, proposing Go
The full five-way evaluation (bash, Python 3, Kotlin Native, Rust, Go)
with the numeric scoring, the Kotlin Native deep-dive, and the
own-namespaces-instead-of-bwrap analysis, ending in a concrete proposal:
Go, stdlib-only, one static binary, sandbox engine behind an interface
so bwrap can later be swapped for native namespaces.

Status proposed — the decision outcome is recorded once made.

# Werkdock
A docker-like sandbox CLI over `bwrap` — filesystem isolation only.
A dock is the enclosed basin in which ships are built: the dock gate controls what passes, the water outside is shared with the whole harbor.
Accordingly, network, uid, `/proc`, `/dev`, and `/tmp` come from the host by contract; that is what makes Werkdock work without root on a Hostsharing Managed Webspace.
Semantics:
- An *image* is a rootfs archive.
- An *instance* is an unpacked, writable directory tree.
- `werkdock run <instance> -- <command>` executes in the sandbox with uid 0 mapped to the calling user.
- `werkdock doctor` checks the host: user-namespace capability, disk and quota headroom.
Status: bootstrap.
The implementation language is proposed in [RFC 0001](docs/rfcs/0001-implementation-language.md) (Go).
Werkdock grows in this subdirectory of the Werkator repository and moves to its own repository once it stands on its own.
It must stay self-contained: no imports from Werkator code, no Gradle coupling to the Werkator build.
The roadmap is session B of [docs/plan/21-werkdock-extraction-and-webspace-install.md](../docs/plan/21-werkdock-extraction-and-webspace-install.md).
