Read-only integration audit: no reproduced automatic-equipment/PMN4 resupply race in installed catalogs.

Production boundaries:
- ERR_AutomaticEquipmentCatalog.Supported excludes EXPLOSIVES, ROCKET_LAUNCHER, attachment/ammo modes. All bits must belong to allowed set; EXPLOSIVES combined with an allowed category still fails.
- Installed vanilla USSR InventoryItems catalog lines777-780 and FIA lines484-487 classify exact PMN4 B05A816C0BF50802 as EXPLOSIVES. Both loaded from installed vanilla PAK, not protected original Escapists overrides.
- Read-only PAK scan of installed RHS StatusQuo+contentpacks, WCS Armaments+Core and BMP: no exact PMN4 catalog override found. Found RHS TM62M/M15AT entries all EXPLOSIVES. Mine marking flags are EQUIPMENT but are not explosive mines. Results retained in catalog-audit.log and mine-catalog-audit.log.
- MineSupplyReady does not wait for Automatic, but that alone is not a demonstrated mine race: installed eligible automatic categories cannot issue PMN4. Other automatic inventory items can consume capacity; finite mine leaf rechecks native storage/CanMove and preserves one-shot submission quarantine, so capacity refusal is ordinary bounded failure rather than additional mine.
- ERR_EnemyEquipment.RegisterGroup deduplicates exact groups; Known(actor) retains original actor identity. Tick suspends existing entry during unconsciousness without resetting grants. Player/captured ownership permanently stops entry; released entries remain known, so later loss of player ownership cannot reroll same original actor. New physical replacement actors are separate identities, not reconnect rerolls.
- Grant m_Rolled and retained m_Operation prevent retry/reroll after completion, rejection, timeout or late callback.

Focused actual-method tests PASS: test_automatic_equipment.py, test_enemy_equipment.py, test_infantry_mine_transfer.py. Logs retained alongside this review. These are extracted methods with native doubles, not native multiplayer qualification. No source patch proposed, no target/reference source edits, no engine/UI actions.

Limit: unsupported future addon catalog misclassification (e.g. PMN4 intentionally marked EQUIPMENT) was not reproduced or defended by speculative extra gate. Active runtime catalog selection can differ from static inspected installed entries; no live catalog query launched.
