The direct write census is tighter in the same direction: the only grounded explicit write of value `8` into `[event+0x7ef]` is `0x004d91b3` inside that same shell helper, while the runtime-side grounded writers still only cover zero-init, copy, `2/3` follow-on seeds, and the later `5` / `2` retags.
Preserved checked control-lane detail now lives in [Periodic company control lane](rehost-queue/periodic-company-control-lane-2026-04-21.md).
- Keep the next static Tier-2 building pass focused on the earlier seed/projection seam into `0x00412d70`, not another broad `BuildingTypes` sweep.
The grounded owner strip is `0x004196c0 -> 0x00414490 -> 0x00416ce0 -> 0x00419230`, and the checked candidate-table exports now keep the concrete scenario-side families explicit too: among the `37` probe-bearing maps, `Port00/Warehouse00` stay at `35/43` on `30` maps and shift earlier to `10/18` on `7`, while `Port01..11` / `Warehouse01..11` stay fixed at `45..55` / `56..66` and the numbered trailer family splits independently at `0x00000001 -> 28 maps` versus `0x00000000 -> 9 maps`. The new crossover matrix stays mixed rather than collapsing to one side too: `35/43 :: 0x00000001 -> 25 maps`, `35/43 :: 0x00000000 -> 5 maps`, `10/18 :: 0x00000000 -> 4 maps`, and `10/18 :: 0x00000001 -> 3 maps`. The checked header-cluster export keeps the same root scan bounded to only `3` families: `0x00000000 / 0x00000000 -> 27 maps`, `0xcdcdcdcd / 0xcdcdcdcd -> 9 maps`, and `0x10000000 / 0x00009000 -> 1 map` (`Alternate USA.gmp`). The load-side handoff is narrower now too: `0x004120b0` explicitly reads `[candidate+0xba]` and `[candidate+0xbb]` as one-byte stream fields, and the very next projection owner `0x00412d70` immediately consumes those bytes in two passes, first `+0xba` and then `+0xbb`, to pick one seed row whose full `0x1f2`-dword body will be cloned or reused for each numbered runtime record. The stock decode side is narrower in the same direction: `0x00414490` does not just copy the `0xb8..0xbb` tail, it already derives the optional plane size from `[record+0xb8] * [record+0xb9] << 5` and uses the high nibble of `[record+0xba]` while materializing the four optional plane buffers at `[record+0xcf/+0xd3/+0xd7/+0xdb]`, before `0x00416ce0` remaps only the bare `port` / `warehouse` names and the later `0x00419230` rebank-or-clone pass consumes any bank-qualified owners. The stock `BuildingTypes` corpus is narrower too: across `77` checked `.bca` files only `MachineShop.bca` carries nonzero selector bytes at `0xb8..0xbb`, while the broader nonzero stock signal lives in the `22`-file `.bty` alias-root family with `dword_0xbb = 0x000001f4`, especially the `TextileMill` branch that already covers `Port.bty` and `Warehouse.bty`. The active open question is therefore which later seed or projection seam turns that already-decoded stock-side shape or selector state together with the fixed numbered cluster into nonzero live `[candidate+0xba/+0xbb]` before `0x00412d70` and `0x00419230` consume it.

The same static pass rules out one lingering false lead too: the earlier suspected `0x00414500..0x00414b14` replay strip is not a separate serializer or import family at all, just the interior plane-decode band of `0x00414490`. The stock `BuildingTypes` corpus is narrower too: across `77` checked `.bca` files only `MachineShop.bca` carries nonzero selector bytes at `0xb8..0xbb`, while the broader nonzero stock signal lives in the `22`-file `.bty` alias-root family with `dword_0xbb = 0x000001f4`, especially the `TextileMill` branch that already covers `Port.bty` and `Warehouse.bty`.
