# Runtime Effect Kind-8 Tier2 Setup Core Note
|
||
|
|
|
||
|
|
This note records the current setup-payload-core comparison across 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`
|
||
|
|
|
||
|
|
The comparison uses the checked `compare-setup-payload-core` surface.
|
||
|
|
|
||
|
|
## Immediate result
|
||
|
|
|
||
|
|
The upstream setup payload already differs across the carrier set.
|
||
|
|
|
||
|
|
Observed differing fields:
|
||
|
|
|
||
|
|
- `payload_word_0x14`
|
||
|
|
- `payload_byte_0x20`
|
||
|
|
- `payload_word_0x3b2`
|
||
|
|
- `candidate_header_word_0_hex`
|
||
|
|
- `candidate_header_word_1_hex`
|
||
|
|
|
||
|
|
## Carrier-set shape
|
||
|
|
|
||
|
|
Current `payload_word_0x3b2` values:
|
||
|
|
|
||
|
|
- `Alternate USA.gmp = 1`
|
||
|
|
- `Chicago to New York.gmp = 2`
|
||
|
|
- `Louisiana.gmp = 2`
|
||
|
|
- `Pacific Coastal.gmp = 1`
|
||
|
|
- `Rhodes Unfinished.gmp = 1`
|
||
|
|
- `Texas Tea.gmp = 3`
|
||
|
|
|
||
|
|
That means `Louisiana.gmp` is **not** unique on `payload_word_0x3b2`.
|
||
|
|
|
||
|
|
Current candidate-header word pairs:
|
||
|
|
|
||
|
|
- `Alternate USA.gmp = 0x10000000 / 0x00009000`
|
||
|
|
- `Chicago to New York.gmp = 0x00000000 / 0x00000000`
|
||
|
|
- `Louisiana.gmp = 0xcdcdcdcd / 0xcdcdcdcd`
|
||
|
|
- `Pacific Coastal.gmp = 0x00000000 / 0x00000000`
|
||
|
|
- `Rhodes Unfinished.gmp = 0x00000000 / 0x00000000`
|
||
|
|
- `Texas Tea.gmp = 0x00000000 / 0x00000000`
|
||
|
|
|
||
|
|
So `Louisiana.gmp` is currently unique among the shipped carrier set on the candidate-header
|
||
|
|
sentinel pair, while `Alternate USA.gmp` stays separately unique on the recognized
|
||
|
|
`rt3-105-map-container-v1` header pair.
|
||
|
|
|
||
|
|
## Current implication
|
||
|
|
|
||
|
|
The upstream side of the Tier 2 strip is now bounded more tightly:
|
||
|
|
|
||
|
|
- the current `Louisiana.gmp` recipe/runtime outlier status is not explained by `payload_word_0x3b2`
|
||
|
|
alone, because `Chicago to New York.gmp` also carries `2`
|
||
|
|
- but `Louisiana.gmp` does stand out on the candidate-header sentinel pair
|
||
|
|
|
||
|
|
So the next Tier 2 upstream question is narrower:
|
||
|
|
|
||
|
|
- whether the unique `0xcdcdcdcd / 0xcdcdcdcd` candidate-header state in `Louisiana.gmp` is
|
||
|
|
relevant to the coupled
|
||
|
|
`0x00435630 / 0x00412d70 / 0x00412fb0 / 0x00412c10`
|
||
|
|
rebuild strip, or whether it is only another container-side artifact unrelated to the shipped
|
||
|
|
`Add Building Warehouse05` row.
