Owner

Phase 2 of design/guix-container-runtime.md (§11). DX for the Guix runtime.

What

up --scaffold-guix — writes a starter .wraptool/container.scm (harness runtime: node/bash/coreutils/nss-certs, no git) when none exists, then continues bring-up. Non-clobbering: an existing/edited manifest is left as-is. Fresh repo → scaffold → up, no manual step.
Prints the chosen runtime (container runtime: guix|devcontainer) so the auto fallback is never invisible.
.mcp.json backup-on-overwrite already shipped in phase 1.

Verified (e2e on Guix host)

Fresh workspace + manifest.scm, up --scaffold-guix --shell=never:

scaffolded .../.wraptool/container.scm (harness runtime; edit to add tools)
container runtime: guix
wrote .../.mcp.json (wraptool @ http://127.0.0.1:8719)
realizing container profile ...

Re-run → container manifest already exists (leaving as-is). Unit test covers write + idempotency + the no-git invariant. build/vet/test/golangci-lint clean.

Deferred

Phase 3 (parity tests/docs polish), phase 4 strict-net (pasta).

Non-clobbering: an existing/edited manifest is left as-is.

Details

e8a4a4474c

Phase 2 of design/guix-container-runtime.md. `wraptool up --scaffold-guix`
writes a starter .wraptool/container.scm (harness runtime: node/bash/coreutils/
nss-certs, no git) when none exists, non-clobbering, then continues bring-up —
so a fresh repo goes scaffold -> up with no manual step. runUp now also prints
the selected container runtime so the auto fallback is never invisible.

(.mcp.json backup-on-overwrite already landed in phase 1.) Verified e2e: fresh
workspace + manifest.scm, `up --scaffold-guix` scaffolds the manifest, reports
`container runtime: guix`, writes .mcp.json, realizes the profile; a re-run
leaves an existing/edited container.scm untouched. Unit test covers write +
idempotency + the no-git invariant.
