# Pinned UE4SS capability evidence

This Companion has inspected the read-only reference repository at commit
`bae91527355f14faa63c1df65f742cc48594ba1b` (`scum_simple_rcon_ue4ss` v0.1.0,
verified build target RE-UE4SS 3.0.1).

## Verified capability

The source implements a game-thread `SendChat <type 0-7> "message"
[SteamID64]` path. A targeted send accepts only a 17-digit SteamID64 that
resolves to a real, currently online `ConZPlayerController` with a live
`UNetConnection`; it fails closed when the reflected
`MiscStatics:SendChatLineToPlayer` schema differs. This can support a
version-bound, typed `player.notify` adapter when the deployed Companion is
given a platform-authorized typed transport. `VersionedAdapter` implements
that contract only for this exact source revision and UE4SS 3.0.1, with fixed
chat type `4`; it cannot accept arbitrary RCON text. Its generated command
text is private transport/audit data and never appears in a command result.

## Explicitly unavailable

The reference contains no versioned server-side producer or documented API for:

- successful player login/logout records;
- raw network identity/fingerprint values suitable for correlation;
- player or vehicle position, or player/vehicle transitions;
- item/reward delivery; or
- skill/attribute read, safe-window checking, or mutation.

Therefore the Companion must not parse invented `LOGIN`/`LOGOUT` lines, upload
semantic events, correlate network identifiers, or claim trajectory, reward,
or game-state-patch support from this reference. The missing contract is a
version-pinned UE4SS extension/API that defines the event or operation schema,
identity binding, acknowledgement/result semantics, and non-production
integration fixture for each capability.
