# Writing and symbol data
|
|
|
|
Milestone 4 stores what a player wrote without deciding what that writing does
|
|
to an Age. Milestone 5 owns grammar validation, symbol interaction, instability,
|
|
and translation into biome, noise, dimension-type, and other world-generation
|
|
configuration.
|
|
|
|
## Symbol catalog
|
|
|
|
The authoritative server catalog loads JSON resources from
|
|
`data/<namespace>/rivencraft/symbols/<path>.json`. The resource ID is the
|
|
symbol ID. For example, `data/rivencraft/rivencraft/symbols/terrain/standard.json`
|
|
defines `rivencraft:terrain/standard`.
|
|
|
|
Schema version 1 contains display metadata only:
|
|
|
|
```json
|
|
{
|
|
"schema_version": 1,
|
|
"name": "symbol.rivencraft.terrain.standard",
|
|
"description": "symbol.rivencraft.terrain.standard.description",
|
|
"category": "rivencraft:terrain"
|
|
}
|
|
```
|
|
|
|
`name` and `description` are translation keys, not arbitrary formatted text or
|
|
executable behavior. `category` is a namespaced organizational identifier.
|
|
Invalid definitions are logged and excluded by the server. Menus and future
|
|
page synchronization must obtain resolved display metadata from the server;
|
|
clients never make a symbol valid by naming it.
|
|
|
|
Rivencraft ships a small catalog covering terrain, biomes, lighting, weather,
|
|
celestial behavior, and features. It exists to exercise the complete writing
|
|
workflow before Milestone 5 implements the full legacy grammar.
|
|
|
|
## Persistent writing
|
|
|
|
`SymbolReference` stores only a namespaced symbol ID. `WritingEntry` is either
|
|
a symbol reference or a baseline link-panel marker. `OrderedWriting` retains up
|
|
to 256 entries in exact player-authored order. All three contracts have both
|
|
persistent codecs and bounded network codecs.
|
|
|
|
Removing a data pack never removes its IDs from saved writing. A missing ID is
|
|
resolved as client-safe **Unresolved Symbol** display metadata while retaining
|
|
the original namespaced ID for diagnostics and later restoration. This is
|
|
deliberately different from treating an unknown symbol as valid grammar.
