# Runtime Effect Kind-8 Tier2 Recipe Signature Note

This note records a direct fixed-layout scan over all 41 bundled `rt3_105/maps/*.gmp` files,
using the already-grounded recipe-book payload layout:

- recipe-book root `0x0fe7`
- book stride `0x4e1`
- line root `0x3f1`
- line stride `0x30`
- imported mode dword at `line+0x00`
- supplied token dword at `line+0x08`
- demanded token dword at `line+0x1c`

The goal is narrower than general recipe-book comparison:

- classify the imported nonzero-mode footprint that can actually feed `0x00435630`
- then check whether `Louisiana.gmp` is unique on that runtime-relevant surface

## Mode-signature groups

Across the 41-map corpus there are 23 distinct nonzero-mode path signatures.

Largest groups:

- 7 maps: no nonzero mode rows at all
  - `East of Mississippi.gmp`
  - `Greenland Growing.gmp`
  - `Mexico.gmp`
  - `Pacific Coastal.gmp`
  - `Russia.gmp`
  - `Southern Pacific.gmp`
  - `War Effort.gmp`
- 4 maps: `book00.line02`, `book01.line02`, `book02.line02`
  - `Argentina Opens Up.gmp`
  - `Central Pacific.gmp`
  - `Eastern Canada.gmp`
  - `Rhodes Unfinished.gmp`
- 3 maps: `book02.line02`
  - `Crossing the Alps.gmp`
  - `Germantown.gmp`
  - `Mississippi Valley.gmp`
- 3 maps: `book00.line02`, `book01.line02`, `book02.line02`, `book03.line02`
  - `East Coast, USA.gmp`
  - `Go West!.gmp`
  - `Ireland.gmp`
- 3 maps: `book00.line02`
  - `Britain.gmp`
  - `Louisiana.gmp`
  - `South East USA.gmp`

So `Louisiana.gmp` is not unique at the coarse nonzero-mode-path level. It belongs to a small
three-map family whose imported mode footprint is just one active line:

- `book00.line02`

## Exact imported signature

When the token lanes are included, `Louisiana.gmp` does become unique in the 41-map corpus.

Current exact imported signature:

- nonzero mode rows:
  - `book00.line02 = 0x00080000`
- nonzero supplied token rows:
  - `book00.line02 = 0x00004080`
- nonzero demanded token rows:
  - `book00.line00 = 0x00010000`
  - `book00.line01 = 0x6c430000`

Exact signature group size:

- `1`

Current exact group:

- `Louisiana.gmp`

## Current implication

This narrows the Tier 2 recipe/runtime question again:

- the decisive runtime-relevant surface is not the broad recipe-book family and not only the raw
  setup-core tuple
- `Louisiana.gmp` is rare but not singular on the imported nonzero-mode-path shape
- it becomes unique only when the token-bearing rows around that minimal imported shape are
  included

So the next concrete comparison question is:

- whether the two mode-shape peers `Britain.gmp` and `South East USA.gmp` diverge from
  `Louisiana.gmp` strongly enough on token lanes and later Tier 2/runtime-facing state to explain
  why only `Louisiana.gmp` currently lines up with the shipped `Add Building Warehouse05` path
