# C1619 — Preserve the meaning of the shared5436 junction

## Question

Which declaredinverse paths actually support the5436 node used by the4900 transport?

## Sources

```json
[
  "SP_MT_Shem_condition.json",
  "translation_cut_domain.json",
  "three_4900_placements.json"
]
```

## Results

```json
{
  "coordinate_BC": 5436,
  "valid_roles": [
    "SP completed primary inverse cumulative Flood",
    "ordinary MT cumulative Shem",
    "MT Conquest-held cumulative inverse Shem when Flood andShem cuts both retained"
  ],
  "different_partition_Shem_BC": 4446,
  "guard": "A coordinate equality preserves each path label; the whole Conquest–Shem inverse is a separate branch."
}
```

## Finding

5436 is the primary SP completed inverse Flood and ordinary MT cumulative Shem; MT also retains it when Flood andShem are separate inverse legs. The whole-Shem inverse branch is4446.

## Reassessment

These source-tagged junctions now support a compact dependency graph; use it to choose what belongs in the explanation.
