Moving civilian traffic discovers ordinary S105/V2101 variants once, with 80% car / 20% existing S1203 van selection. The native catalog contained 19 moving-car entries. Rally cars and tractors remain outside moving traffic.
T601 stays in the parked pool. Two native road locations left its original AI driver seated without starting the engine; the diagnostic recorded engine off, handbrake on and negligible movement. V2101 drove on those tests. No speculative engine or vanilla prefab override was added.
Optional Rally Z7211 civilian tractors can appear beside supported barns and cowsheds. Farm selection is capped at 15%, shares the existing parked fleet limit, and uses wider ground/collision and taller visibility checks. Existing claim and distant cleanup rules remain in use. No new DLC dependency.
The admin panel shrinks only when necessary to fit the viewport, without changing the user's saved UI scale. Baseline 150% scale clipped vertically; final native measurements fit at 75%, 100%, 125% and 150%.

Checks without changes

Installed ACE Magazine Repack 1.4.3 already handles inventory drag/drop through its SCR_InventoryMenuUI.MoveItemToStorageSlot override and server-side ammo transfer. It checks matching magazine wells and available capacity. This is a source inspection, not a new multiplayer ACE/RHS interoperability test. No duplicate repacking implementation was added.

Site squads, patrols and related groups already request queued native spawning. Town garrisons instead create one actor per background callback, with mission placement and exclusion checks. Convoys and aircraft have explicit AI activity requirements. The isolated native world reported partial fill and dormancy enabled with an active AI limit of 128; its zero active count is not a production load measurement. No priority or global dormancy change was made. Native group despawn/recreation can reset inventory and health, so further optimization needs to preserve the mission's finite ammunition, casualties and crew continuity.

Evidence and limits

final.log records both original S105/V2101 drivers travelling over 100 metres, native tractor placement through production Plan/Pending ground, visibility and collision checks, and UI geometry. The fixture supplies a stationary observer and a spawned native barn; it forces that barn's selection to exercise placement. It does not test random farm frequency or multiplayer observers. UI measurements use the 501x225 Workbench game viewport, not manual controller/TV usability.

runner.json reports smoke-completed, unchanged source/external inputs and confirmed cleanup. production-source-comparison.json verifies all changed production scripts/layout match the tested snapshot. The test-only probe and launch manifests are included. Tests used hidden, muted Gamescope and a disposable Proton prefix; the normal mission startup was suppressed in the fixture.

The strict runner still exits nonzero because the complete log contains resource errors: external localization references, legacy vehicle prefab fields, a DLC ownership request failure, and fixture path-only resource lookups. There are no Game script compilation errors or VM exceptions in the final run. Tractor resource and seat checks passed, but live client DLC entitlement/driver access is unqualified. This is not a clean-all-engine-logs or dedicated multiplayer certification.

repository-check.log records the full passing repository validator. After the final T601 exclusion, catalog rules, traffic, garage lifecycle, panel fit and menu source tests passed again. ui-baseline.log and t601-diagnostic.log preserve the earlier failures that informed the changes. Other exploratory runs included a test-only API typo and observer-fixture failure; neither changed production logic.

Workbench subsequently confirmed successful upload of 0.0.143 at 12:35:36 on 2026-11-06. See publication.json; the changelog version was recorded with tools/workshop_changelog.py --published before committing this release.
