# Original galaxy-map system connectors

This is an offline analysis of the pinned original executable with SHA-256
`6891f70a021fa9f3a0e00458c284f48d1226e68ae7fc02ad48081aed47857e93`.
The matching image is `artifacts/ship-model-reference/client-copy/EliteDangerous64.exe`.
All function and data addresses below are RVAs in that image. The Steam image
was subsequently updated; these addresses are not a compatibility claim for
the updated executable.

## Setting and renderer

The original string `ShowSystemConnectors` is at `52A1408`. Its entry in the
settings name table is `529A638`, index **49 / 0x31** relative to table start
`529A4B0`. UI builder `3A819C0` obtains setting `0x31` through settings vfunc
`+1F0` and creates its checkbox with that same setting index.

Line renderer **3AF2E60** obtains exactly this setting and applies it to line
categories **0 and 1**. Categories **2 and 3** bypass this switch. There are
also original mode exclusions: raw `RealisticView == 2` with raw
`PoliticsMode == 1` disables categories 0/1; raw `RealisticView == 4` with
visualisation mode 4 also disables them. These raw values must retain their
separately verified current-version meanings.

The renderer resolves component ID global `5F05DD0` through the local-player
component container. Its type getter is `2600870`, interface vtable `529E328`.
Vfunc `+130` / **2600D50** returns:

```text
interface + 0x280 + mode * 0x2E8
```

There are seven vector headers, stride `0x18`, and each line has two float4
endpoints, stride `0x20`. This is the original NavRoute component already used
by `Navigation.Fsd.cs`, rather than a separate grid projection component.

## Actual endpoint geometry

NavRoute producer **25FED60** establishes the geometry directly. It selects a
mode block at:

```text
block = objectBase + 0x168 + mode * 0x2E8
```

At its final append block (`1425FF694` in the decompiler output), the first
header offset is `block + 0x170`, or category 0. It instead selects
`block + 0x188`, category 1, if the edge's float at graph-node offset `+0x3C`
exceeds the threshold returned by **2604810(objectBase, mode)**. The first
header therefore equals `interface(+0x58) + 0x280`, matching the renderer.

The appended record copies:

```text
endpoint 0 XYZ = graph node A + 0x20 (three original floats)
endpoint 1 XYZ = graph node B + 0x20 (three original floats)
endpoint 0 W = 0
endpoint 1 W = 0
```

The surrounding loop resolves two graph nodes using their system IDs and
adjacency lookup, skipping duplicate edge pairs. Both endpoints retain their
full original XYZ. It does not substitute zero, focus height, or grid height
for either Y coordinate.

Consequently, **ShowSystemConnectors controls connections between star
systems**, with categories split by the original distance threshold. It does
not describe the vertical line from a star down to a map plane. Separately
drawn route categories 2/3 remain visible independently of this option. This
analysis does not establish the original setting for any grid stalks.

## Implementation consequence and evidence files

Importing `ShowSystemConnectors` into the tool's jump-connection option is
consistent with the original geometry. Reusing that option as an additional
gate for grid stalks conflates two distinct geometries; stalk visibility needs
its own verified setting or an explicitly tool-specific option.
