feat(P07a/b/c): runtime abstraction — 5 backends (process/podman/wasm/pve-vm/pve-ct), C-01 satisfied (REQ-078)
P07a/b/c — Runtime abstraction interface + 5 implementations.
Runtime interface (internal/runtime/runtime.go, REQ-078):
- Runtime interface { Prepare, Start, Stop, Status }. Alloc struct carries
Runtime field (changeable on migration per R-004). Registry keyed by
runtime.one_of. DefaultRegistry(transport) registers all 5.
Process (internal/runtime/process.go):
- ProcessRuntime wraps os/exec (LOCAL testing only; production uses systemd
emitter). SIGTERM grace 10s then SIGKILL.
Podman (internal/runtime/podman.go):
- PodmanRuntime via sshpush.Transport. podman pull/run/stop/rm/inspect.
Wasm (internal/runtime/wasm.go, gate C-01 SATISFIED):
- WasmRuntime uses wasmtime CLI (apt-installed on peer) via SSH exec. NO CGO
— does NOT import bytecodealliance/wasmtime-go. CGO_ENABLED=0 build
passes. D-002 cross-compile story preserved. D-187 recorded.
PVE (internal/runtime/pve.go):
- PveVMRuntime (qm create/start/stop/status) + PveCTRuntime (pct
create/start/stop/status) via sshpush.Transport. VMID = hash(alloc.ID)%99999.
C-01 evaluation: internal/runtime/C01_WASMTIME_CGO_EVAL.md. Auto-decision
(full autonomy): wasmtime remains primary; CLI-via-SSH avoids CGO entirely.
D-187 in PROJECT.md.
23 packages pass, 20 bats pass, gofmt clean, verify-reqs 90 consistent.
92.7% coverage on internal/runtime.
