Pre-unlock wave U3 (highest-ROI). Task 7 from CONVERGENCE-PLAN — consolidate 2 provision-*.sh scripts into Rust via Backend trait. Old shells (provision-hetzner.sh, provision-vultr.sh) had identical 6-subcommand surface (create|status|destroy|list), log/die/check_deps helpers, idempotency contract. Sole delta: hcloud vs vultr-cli. RULE 0.2 says Rust-first when >50 LOC + growth expected. New crate _primitives/_rust/kei-provision/: - src/backend.rs (58 LOC) — Backend trait: create/status/destroy/list; CreateOpts and ServerInfo structs - src/backends/hetzner.rs (143 LOC) — shells to `hcloud server ...` --output=json, parses JSON response, honors HCLOUD_TOKEN env (RULE 0.8) - src/backends/vultr.rs (189 LOC) — same pattern, `vultr-cli instance`, honors VULTR_API_KEY env - src/exec.rs (100 LOC) — Command runner + PATH-aware env preservation - src/b64.rs (49 LOC) — minimal user-data base64 encoder; zero transitive deps - src/main.rs (141 LOC) — clap CLI `kei-provision <backend> <cmd>` - tests/backend_smoke.rs (184 LOC) — tempdir PATH-inject fake hcloud + fake vultr-cli, no real cloud. Mutex-serialized (Rust test parallelism). Tests: 11/11 (3 b64 unit + 8 backend_smoke integration). Coverage: hetzner status present/absent/list, vultr status found/absent/destroy idempotent, unknown-backend error, CreateOpts default. Old shells kept with superseded-v0.17 header — install.sh still copies them, legacy scripts still work. New users get kei-provision binary. harden-base.sh untouched (different lifecycle — runs on target VPS). Backend trait factored to accept aws/doctl/linode follow-ups without re-architecture. Workspace Cargo.toml: +kei-provision member (1 line). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
