+## Compact-family split inside the checked peers
+
+The current runtime-facing split is not just “dispatch rows present versus absent.” The checked
+peer maps also diverge inside the broader `nondirect-ge1e-h0001-0007` compact family:
+
+- `Louisiana.gmp` reaches the checked add-building strip on
+  - `nondirect-ge1e-h0001-0007-0000-5200-0200-p0000-0000-0000-ffff :: [7:0]`
+  - with decoded label `Add Building Warehouse05`
+- `Britain.gmp` keeps `nondirect-ge1e-h0001-0007-0000-4a00-0200-p0000-0000-0000-ffff`
+  but no add-building dispatch-strip rows
+- `South East USA.gmp` keeps several other `0007` mids
+  - `...-3100-...`
+  - `...-3500-...`
+  - `...-3800-...`
+  - `...-3b00-...`
+  - `...-4200-...`
+  and again no add-building dispatch-strip rows
+
+So the current checked peer split is now:
+
+- same coarse mode-shape family
+- different exact token-bearing `book00` signature
+- different `h0001-0007` mid-word family at runtime
+- only `Louisiana.gmp` currently reaches the `5200 :: [7:0]` add-building strip
+
+## Minimal imported-cluster split
+
+The next corpus pass sharpens that again.
+
+`Louisiana.gmp` is not the only map that reuses pieces of the apparent `lC / 0x00080000 /
+0x00004080` cluster:
+
+- `Ireland.gmp` carries
+  - `book02.line01 = demanded 0x6c430000`
+  - `book02.line02 = mode 0x00080000, supplied 0x00004080`
+  - plus additional active rows in `book00`, `book01`, and `book03`
+- `Eastern China.gmp` carries
+  - `book02.line00 = demanded 0x00010000`
+  - `book02.line01 = demanded 0x6c430000`
+  - `book02.line02 = mode 0x00080000, supplied 0x00004080`
+  - plus additional active rows in `book00` and `book01`
+
+But the exact three-row cluster as the *entire* nonzero imported recipe surface is unique to
+`Louisiana.gmp` in the 41-map corpus:
+
+- `book00.line00 = demanded 0x00010000`
+- `book00.line01 = demanded 0x6c430000`
+- `book00.line02 = mode 0x00080000, supplied 0x00004080`
+
+No other bundled map keeps exactly that three-line imported set and nothing else.
+
+That matters on the runtime side too:
+
+- `Ireland.gmp` still has no add-building dispatch-strip rows at all
+  - `add_building_dispatch_strip_records_missing_trigger_kind = 0`
+  - checked `0007` family stays on `...-6300-...`
+- `Eastern China.gmp` also has no add-building dispatch-strip rows at all
+  - `add_building_dispatch_strip_records_missing_trigger_kind = 0`
+  - checked `0007` mids stay on other families such as `...-a100-...`, `...-a600-...`,
+    `...-b100-...`, `...-b700-...`, `...-cf00-...`, and `...-d100-...`
+
+So the stronger current read is no longer just “the `0x00080000 / 0x00004080` triplet exists
+somewhere.” It is:
+
+- `Louisiana.gmp` is the only bundled map whose whole imported nonzero recipe surface collapses to
+  that exact three-row cluster
+- maps that merely reuse pieces of the cluster do not currently reach the same add-building strip
+
+That makes the next Tier 2 question smaller again:
+
+- whether the `5200 :: [7:0]` add-building strip is tied to that minimal imported-cluster shape
+  specifically, rather than to the presence of any one of its component token rows in a broader
+  recipe profile
