ZoneFilePack reads and writes the editor's packed files: named entries whose data is sd0, one entry for a single file or the zone, terrain, scenes and triggers of a whole map. Every length is checked, data that is not sd0 or has a chunk over 256 KiB is refused, and only a name's base name is used. ZoneFilePush makes a set of what was sent (one file replaces that file in the zone's set), checks it and applies it like any other set. The override store links a set's files instead of moving them, so a file the zone already has can be carried into its next set, and one change at a time is made in an override folder whichever server makes it. The asset manager can read the client's own file past an override. Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>

/**
|
|
* Taking a zone's files as the game client's level editor sends them (ZoneFilePack) into the zone's set: unpacked,
|
|
* made into a whole set, checked like any other set (ZonePublish) and applied (ZoneOverrideStore), or refused with
|
|
* nothing written. A whole map is the zone's new set. One file replaces that file in the set the zone has and keeps
|
|
* the rest; a set always has the zone's .luz, the client's own when none was sent or kept.
|
|
*
|
|
* Only reads the bytes it is given and files under the override folder: no connection, database or setting, so it
|
|
* runs on a worker thread.
