+# Runtime Effect Kind-8 Title Overlap Note
+
+This note tightens the current `0x00442c30` title-fixup hypothesis for the shipped add-building
+carrier maps.
+
+## Grounded title-hint scan
+
+The checked report
+`artifacts/exports/rt3-1.05/add-building-map-title-hints.json`
+scans the six bundled add-building carrier maps:
+
+- `Alternate USA.gmp`
+- `Chicago to New York.gmp`
+- `Louisiana.gmp`
+- `Pacific Coastal.gmp`
+- `Rhodes Unfinished.gmp`
+- `Texas Tea.gmp`
+
+against the currently grounded `0x00442c30` title set:
+
+- `Go West!`
+- `Germany`
+- `France`
+- `State of Germany`
+- `New Beginnings`
+- `Dutchlantis`
+- `Britain`
+- `New Zealand`
+- `South East Australia`
+- `Tex-Mex`
+- `Germantown`
+- `The American`
+- `Central Pacific`
+- `Orient Express`
+
+Observed result:
+
+- `5 / 6` carrier maps show at least one grounded title hit.
+- `1 / 6` carrier maps show an adjacent embedded `.gmp` reference plus grounded title.
+- `1 / 6` carrier maps show a same-stem pair.
+
+The only strong same-stem overlap is:
+
+- `Louisiana.gmp`
+  - embedded map reference: `Dutchlantis.gmp` at `0x73d0`
+  - grounded title hit: `Dutchlantis` at `0x73d0`
+  - byte distance: `0`
+
+All other current carrier-map overlaps are weaker late-string hits:
+
+- `Alternate USA.gmp`: `Germany`, `France`, `Britain`
+- `Chicago to New York.gmp`: `Germany`, `France`
+- `Pacific Coastal.gmp`: `Central Pacific`
+- `Texas Tea.gmp`: `Germany`
+- `Rhodes Unfinished.gmp`: no current grounded hit
+
+## Louisiana versus Dutchlantis runtime-event comparison
+
+Direct `inspect-smp` comparison shows the strong same-stem title overlap does **not** carry over
+to the actual add-building dispatch strip.
+
+`Louisiana.gmp`:
+
+- `nondirect_compact_record_count = 14`
+- add-building dispatch record index: `5`
+- add-building label: `Add Building Warehouse05`
+- add-building signature family:
+  `nondirect-ge1e-h0001-0007-0000-5200-0200-p0000-0000-0000-ffff`
+- add-building condition tuple family: `[7:0]`
+- add-building cluster:
+  `nondirect-ge1e-h0001-0007-0000-5200-0200-p0000-0000-0000-ffff :: [7:0]`
+
+`Dutchlantis.gmp`:
+
+- `nondirect_compact_record_count = 15`
+- no add-building dispatch rows
+- current dispatch-strip grouped descriptor labels:
+  `Company Variable 1`, `Company Variable 2`, `Company Variable 3`
+
+## Current implication
+
+The title-fixup branch remains possible for narrow scenario-specific retagging, but the strongest
+current filename/title overlap (`Louisiana -> Dutchlantis`) does not reproduce the actual
+add-building dispatch cluster. That weakens `0x00442c30` as the primary explanation for the
+shipped add-building carrier strip and keeps the stronger bias on the non-title-specific late
+bringup owners between ordinary reload `0x00433130` and final kind-`8` service `0x00432f40`.
