Adds operations/services.py: a fixed ManagedService allow-list (act-runner, act-runner-rust, vmware-host, ci-web) with find_service/service_states/control_service. control_service builds an argument list only (never shell=True), validates the action against ALLOWED_ACTIONS (ValueError->400), refuses stop on restart-only services (ci-web, allow_stop=False) without building a command, and defers ci-web's own restart via 'sudo -n systemd-run --on-active=2 systemctl restart ci-web.service' so the HTTP response returns first.
Route POST /services/{service_id}/{action} in web/routes.py mirrors vms_remove: require_user + require_csrf + two-step confirm gate + one audit entry per stage; unknown id / bad action / disallowed-stop short-circuit to 400 before any subprocess or audit; the vmware-host confirm step warns with the active-VM count. New /services read partial with state-aware Start/Stop/Restart buttons, polled every 15s.
deploy/sudoers.d/ci-web grants ci-runner exact-command NOPASSWD for exactly these nine systemctl lines plus the systemd-run deferral — no wildcards, no bare systemctl, no ci-web stop; setup-web-linux.sh installs it mode 0440 and validates with 'visudo -cf', rolling back on failure. Config gains [web].managed_services override; docs/WEB-UI.md documents the panel + security model.
Gates: 1044 tests pass (46 new security/unit tests), coverage 94.20%, ruff + mypy --strict clean. Not yet deployed: sudoers install + prod-venv reinstall + ci-web restart are a human privilege-boundary step.
Default on, because the cache is safe by construction rather than by
convention: it engages only where a Cargo.lock exists, and refuses to publish
anything the prune assertion cannot vouch for. Two independent off switches --
the flag for one job, `enabled = false` for the host.
The store root is resolved after the environment overrides are applied, so
CI_ROOT relocates it along with everything else, while an explicit root in the
config still wins. Both directions are covered by tests.
Also asserts that the Windows branch never receives the argument at all: the
cache is Linux-only and the two branches stay separate, per AGENTS.md.
Eliminates VMware-Tools IP-detect polling (observed: 39–177 s variance on
Linux host B7 benchmark). When [ip_pool] is configured the orchestrator:
1. Allocates a slot IP from a JSON-backed pool (fcntl-locked on Linux)
2. Injects guestinfo.ip-assignment / netmask / gateway into the cloned VMX
before vmrun start
3. Skips _wait_for_ip entirely — uses the pre-assigned IP immediately
4. Releases the slot in _destroy_clone (all paths: success/failure/interrupt)
