Auto Warz — Data Dictionary¶

Document Type: Reference Version: 0.11 Status: In Progress Last Updated: 2026-09-13 Vault destination: 05_Reference Related: [00_Canonical Design Facts](<../04_Project Management/00_Canonical Design Facts.md>) · AGENTS.md (repo root, outside the site) · [06_Design Session Decision Log](<../04_Project Management/06_Design Session Decision Log.md>)

Purpose¶

One term, one meaning, everywhere. This document exists because the same thing has repeatedly been given several names across the vault and the code, and the drift was only ever caught by accident.

Real examples that motivated it: a storage building called both Storage Chest and Buffer Chest in two documents while being one building; Solar Panel and Solar Collector for one building across two documents; Wood first named as the Biomass Burner's fuel, then wrongly deleted as a duplicate, then restored as a substance once biomass was recognised as a category; and tier, form, medium and phase used interchangeably for four different ideas.

Rules for this document:

If a term is here, use exactly this word. Do not introduce a synonym.
If a term is not here and you need one, add it here first, then use it.
Deprecated words are listed with their replacement. Do not reintroduce them, including in code identifiers, UI labels and asset filenames.
Where a term's meaning is not yet decided, it says so and names the open item. Do not resolve it by usage.
This document defines vocabulary and schema. It does not make design decisions. Where it disagrees with 00_Canonical Design Facts, the canonical page wins.

0. Scope Vocabulary¶

The most fundamental section, numbered zero because everything else assumes it.

The word session was overloaded: 01_Master GDD and 08_Research Tree Design used it to mean the whole playthrough, other documents used it to mean one sitting. These four terms replace that.

Term	Meaning
World	The persistent universe. One galaxy seed plus all changed state: factories, planets, ownership, credits, wreckage. This is the save file. Identified by an ID, never by its name — two players can both name a world "Tarn". Worlds are private and parallel; nothing passes between them except the account.
Session	One continuous run of a world, from load to quit. A sitting. No game state belongs to a session. It is a window of time, nothing more.
Account	The player across all worlds. Level, cosmetics, Engineering Research, saved designs, faction reputation, motherships.
Planet	A player's own territory inside a world. Where their factory lives.
War	A separate shared instance, hosted by a player or a dedicated server. The only shared place. Many private worlds plug into one war through their gates.

A world is the data. A session is the world in motion.

Consequence for research: Factory Research is world-scoped, not session-scoped. It resets in a new world and survives a logout. See [35_Economy Design](<../01_Design Documents/Systems/35_Economy Design.md>).

0a. Phase Vocabulary¶

The word phase is doing two unrelated jobs, on two unrelated axes. Both are legitimate. Neither may be written bare.

Term	Meaning	Owned by
Release phase	What players get, and when. Two of them: Phase 1 (everything except war) and Phase 2 (war). The seam is war, not the planet surface	`[02_Scope & MVP Document](<../01_Design Documents/02_Scope & MVP Document.md>)`
Release	A shipped build inside a phase. Three across the two phases: the Launch release and the Space Update (both Phase 1, both Early Access), then the War Update (1.0)	`[02_Scope & MVP Document](<../01_Design Documents/02_Scope & MVP Document.md>)`
Development phase	The build order. Phase 0 Foundation, Phase 1 Prototype, Phase 2 Core Factory, Phase 3 Factory Depth, Phase 4 Multiplayer, each holding milestones M`<phase>`.`<n>`	`[ROADMAP](<../04_Project Management/ROADMAP.md>)`

They do not line up, and they never did. Development Phase 2 (Core Factory) is work inside release Phase 1. Development Phase 4 (Multiplayer) is co-op, which ships in the Launch release, still Phase 1. A sentence that says "Phase 2" without saying which axis is ambiguous, and several documents were read wrongly because of it.

Every design document carries a Phase field¶

Convention, applied 2026-09-05 across all 47 documents in 01_Design Documents/ and 06_Outpost/.

> **Phase:** Phase 1 — Launch release

Permitted values: Phase 1 — Launch release, Phase 1 — Space Update, Phase 2 — War Update, Outpost Mode — separate track. A document whose contents span more than one says so in the same line, naming which part goes where.

Note the phase numbers on the first two. Both the Launch release and the Space Update are Phase 1, because space is the planet layer reaching further rather than a different game. Only war is Phase 2.

This exists because for six months exactly one document stated its phase, and the only assignment anywhere was a hand-written feature list in [02_Scope & MVP Document](<../01_Design Documents/02_Scope & MVP Document.md>) that was written before most of the documents it was meant to cover existed. A system now cannot be designed without someone deciding when it ships, and the scope document names systems and points at owners rather than duplicating their contents.

Milestone IDs M2.4, M3.1 and so on are an interface, referenced across the vault and read by tooling. Development phases are never renumbered. If the build order changes, milestones are added or marked skipped, never renumbered.

0b. Multiplayer Vocabulary¶

Multiplayer is the umbrella. It has two forms, and they ship at different times, which is why the bare word caused 02_Risk Register and 02_Scope & MVP Document to contradict each other for six months (OI-355).

Term	Meaning	Ships in
Multiplayer	The umbrella. Never write it bare when the distinction matters	—
Co-op	More than one account in the same world, building the same factory. Guests join the owner's world. Authoritative host, state sync, join and leave	Phase 1, Early Access
War multiplayer	Many separate private worlds plugged into one shared war instance through their gates. Needs gates, war hosting, contribution accounting, factions, matchmaking	Phase 2, the War Update

Co-op does not need a gate, a war, or a shared instance. It needs one world and more than one pair of hands. That is the whole difference, and it is why one can ship years before the other.

The world is still owned by the account that created it. Guests are guests: they build in the owner's world, and nothing about ownership, saving or the world's identity changes because someone else is present.

1. Resource Vocabulary¶

Term	Meaning
Resource	Anything the factory produces, consumes or moves. Identified by a stable `id`.
Category	The family a substance belongs to — biomass, metal, mineral, chemical. Load-bearing: a recipe may accept any substance in a category. Decided, not yet implemented.
Substance	What a thing is specifically — wood, algae, iron, water, coal. The identity. Never changes. Decided, not yet implemented.
Type	Processing state: `RAW` / `REFINED` / `COMPONENT`. What `tier` was reaching for. Decided, not yet implemented.
Wood	A substance in category `biomass`. Not deprecated — an earlier pass wrongly collapsed it into the category name.
Algae	A substance in category `biomass`. Not a fuel — it feeds biofuel, which is.
`unit_size`	How much Silo capacity one of this substance consumes. A Silo of capacity 10 holds two things of `unit_size` 5. Makes storage spatial rather than a count. Decided, not yet implemented.
`fuel_value`	Energy per unit, on the substance. There is no `fuel_type`; burners carry their own accepted-fuel list.
Phase	`SOLID` / `LIQUID` / `GAS`. The state a substance is in. Changed by heat and chemistry. Determines transport. Decided, not yet implemented.
Item	A resource in `SOLID` phase. Discrete, ordered, countable. Rides belts.
Fluid	A resource in `LIQUID` or `GAS` phase. Rides pipes. Fungible — see pool below.
Gas	A fluid whose phase is `GAS`. Mechanically a fluid; the distinction matters only at the Router.
Barrel	A steel container holding a liquid. A filled barrel is an ordinary `SOLID` item, so it rides belts like any other solid. Barrelling and debarrelling are ordinary recipes. There is no "form" axis.
Cylinder	A pressure vessel holding a gas. Rated for how hard it holds, where a barrel is rated for what it holds. The tiering family: its rungs widen the temperature range, which is how more gas fits in. Named rungs, never "Mk" — Mk is a building concept (Canonical §4) and a cylinder is an item.
Block	A version of a ship design. Revising a blueprint makes a new Block; a ship remembers the Block it was built from and keeps it until refitted. ⚠️ Never "Mk" — Mk is a building concept (Canonical §4: two tracks, applied in place by upgrade kits) and ships stand beside buildings that have real Mk levels. Shipyard Mk and mothership frame Mk are unaffected: those are buildings.
Refit	Bringing one ship up to a newer Block, at a Shipyard, per ship, at a cost. Priced by the salvage rule: the new parts, plus the continuous material cut through to reach them. Never changes the hull.
Decommission	Breaking a ship up at a Shipyard. Not a refund — the salvageable parts land in the yard's store as ordinary items and must be dealt with.
Salvage rule	Discrete parts survive being unbolted; continuous material — wiring, piping, plating, structure — is destroyed being cut through. One rule prices refit and decommission in both directions. ⚠️ A refit must always destroy less than a decommission, or scrap-and-rebuild undercuts upgrading.
Wreck (ship)	What a destroyed ship leaves. Unlike a building wreck, which is restored in place, a ship wreck must be recovered — yields a lossy subset of its salvageable parts, with no per-part condition tracking.
Ambient rule	What state a substance is in at ambient decides how it travels, because that is the moment it is encased: solid rides as an ordinary item, liquid in a barrel, gas in a cylinder. Makes the container unique by construction rather than by judgement. `[41_Fluid Packaging & Carriage Design](<../01_Design Documents/Logistics/41_Fluid Packaging & Carriage Design.md>)` §1.1.
Queue	How belts behave. Items keep identity, order and position, so they can be filtered and counted individually.
Lossy loop	Any recovery, capture, reprocessing or recycling mechanic. Recovers most, never all — a loop that closes completely removes the decision it was meant to create. Canonical §12b.
Pool	How pipes behave. `PipeNetwork` pair-equalises, so fluid has no position and no order and a connected network drifts toward one level. This is why belts can filter per item and pipes cannot.

⚠️ tier is deprecated. See §5.

2. Building Vocabulary¶

Term	Meaning
Building	A placed structure that sits on a base, has ports, a base ring and at least one module slot.
Base	The universal donut base every building sits on. Footprint identical to the building. Carries the port band, the base ring and the Mk accent tabs.
Port	A cell on the base's top face, configurable `DISABLED` / `INPUT` / `OUTPUT` with an optional resource filter. Carries `ITEM` and `FLUID` only; power never uses ports.
Base ring	The perimeter band carrying fault status. Unlit when healthy.
Head	The building half of a head-plus-extension pair. Ordinary building in every respect. Examples: Station Head, Control Hut, Pond Head.
Extension	A piece attached to a head that is not a building: no ports, no module slots, no base ring. Examples: Freight Platform, Fuel Platform, Greenhouse Bay, Pond Bay.
Bay	An extension belonging to a farm head. Specific case of extension.
Module	A crafted item installed into a fixed roof slot. Adds capability.
Module slot	A fixed roof position. Count derives from footprint size class plus Machine Mk, range 1 to 6. Never researched.
Base Mk	Upgrade track governing port throughput and filtering. Shown by the outer tab row.
Machine Mk	Upgrade track governing processing speed, recipe capability and module slots. Shown by the inner tab row.
Upgrade kit	One of four crafted items that raise a building's Base or Machine Mk in place. An upgrade changes level and nothing else.

3. Transport Vocabulary¶

Term	Meaning
Belt	Carries `SOLID` resources. Passive: no power draw, a one-time material cost that runs free forever.
Pipe	Carries `LIQUID` and `GAS` resources. Pressure-based, pair-equalising.
Router	1×1 building, four configurable ports. Replaces Splitter, Merger and Filter Splitter. Configured `ITEM`, `LIQUID` or `GAS` at placement; a gas Router cannot route liquid.
Underground Belt	A belt variant, not a routing decision.
Rail / track	Passive like a belt: a one-time material cost that runs free. The locomotive burns fuel, not the track.
Station Head	The building half of a station. Holds schedule and name.
Freight Platform	An extension, one per wagon.
Item Lift	Vertical structure carrying items between levels. Paired: same grid cell on both levels.
Fluid Riser	Vertical structure carrying fluids and gases between levels. Paired.
Power Conduit	Vertical structure carrying power between levels. All ports `DISABLED`. A rated link between two grids, not a merge.
Drone	Flying carrier. Battery-limited, recharges by hooking onto power poles. Cannot fly underground; changes level via a vertical shaft.
Cache box	The container a drone carries. Payload capacity is a property of the box, not the drone.
Quantum travel	Late-game player-to-player async trade channel. Never to yourself.

Transport is derived from phase, never stored on a resource. Solids ride belts; liquids and gases ride pipes.

4. Storage Vocabulary¶

Term	Meaning
Silo	Solid storage. Vertical column with a physical fill window. Holds one substance, never mixed — a fill window cannot display a mixture. Capacity is a number of units, so what it holds depends on each substance's `unit_size`.
Tank	Fluid and gas storage. Single-fluid, by the same rule the pipe no-mixing rule already implies.
Packing station	A building that packs loose substance into cache boxes for drones. The centralised route: belt or pipe in, drones collect.
Packing module	A roof-slot module that packs on the building itself. The local route: no belt run, costs a slot.
Buffer	What a building holds — its recipe inputs and outputs, per substance, in a small amount. Machines buffer; Silos store. Different rules, deliberately.
StorageRole	`UNASSIGNED` / `DEPOSIT` / `CONSTRUCTION`. Named for what Genesis does with the building. `UNASSIGNED` = both, the default.

4a. Power Vocabulary¶

Term	Meaning
PU	Power Units. A rate. Generator output, building draw, conduit capacity and transformer ratings are all PU.
PU·s	Energy. A rate held for a time. Accumulator capacity and the energy content of a fuel item are PU·s. A Smelter drawing 30 PU for ten seconds spends 300 PU·s.
Grid	A set of buildings sharing supply. Regions joined only by distribution stay separate grids until linked by transmission or a Power Conduit. Conduits link grids; they never merge them.
Connection	Whether a building is on a grid at all. A fixed radius, topological.
Reach	Whether usable power actually arrives. Electrical, and it contracts as circuit load rises. A building can be connected and still receive nothing.
Shed	A building switched off by the power system to protect the grid. Not a fault in the building. Two independent causes: grid deficit and local under-voltage.
Brownout	The condition, not the mechanism. Covers both shed causes; say which one is meant.
CER	Core Energy Rating. Seeded per planet, 200–2800 PU, and the only generation figure unknown until the planet exists.

Authority for all of these is [25_Power System Design](<../01_Design Documents/Systems/25_Power System Design.md>). Storage is measured in PU·s and not in PU, which is the one unit error already made once in the vault.

4b. War Vocabulary¶

Term	Meaning
Gate	The building in a world that links it to a war. Has throughput, latency and a continuous power draw. One gate, one concurrent war, maximum three. Powered down between wars.
Forward Depot	A faction's shared warehouse at a war, and the destination of every friendly gate. Holds only what was delivered and can run dry. Free draw for faction members.
Supply umbrella	The area within which a mothership or depot delivers supply. Equal to drone round-trip range from the pit — a battery, not an arbitrary circle. Area-based, matching power is area-based on the planet.
Command range	Maximum operating distance of a ship from its mothership, beyond which it is out of contact and must return. Per class.
Contribution	Goods delivered through a gate to a Forward Depot. A permanent, account-scoped record, not a currency. Also literally the depot's stock.
Credits	A combat reward, earned by destroying enemy ships. War-scoped. Splits between faction upgrades and a personal settlement share.
Engineering Points	Granted by player levels. Buys Engineering Research, which is capacity and efficiency only. Account-scoped.
Adrift	A ship disabled by critical module loss.
Derelict	An abandoned adrift ship. Salvage for anyone.
Recovery	Bringing a stranded or crippled mothership home. Exists for motherships only; escorts are left where they fall.
Stranded	A mothership that cannot withdraw, usually for want of fuel or a closed gate. Not destroyed.

4c. Measurement Vocabulary¶

Three kinds of number. They are never combined.

Kind	Test	Example
Efficiency	Has a denominator: output per unit spent	fuel efficiency, ammunition efficiency
Power	Has units over time	offensive power, in kills per minute
Coverage / capacity	A fact, spatial or counted	armour coverage per face, storage capacity

Efficiency needs a denominator. Power needs units. Coverage is a fact.

A single aggregate is rankable, and anything rankable gets optimised until every player builds the same thing. See [34_Ship & Mothership Editor Design](<../01_Design Documents/Systems/34_Ship & Mothership Editor Design.md>) → What the Editor Shows.

5. Deprecated Words¶

Do not use these, anywhere — prose, code identifiers, UI labels or asset filenames.

Deprecated	Use instead	Why
Multiplayer (bare, where the form matters)	Co-op or war multiplayer	Two systems, two release dates. See §0b
Phase 1 / Phase 2 / Phase 3 (bare, no axis)	Release phase N or development phase N	Two unrelated axes share the word. See §0a. There is no release Phase 3
Milestone (meaning a progression beat)	Beat	`36_Progression Arc Design` calls them beats. Milestone means an `M<phase>.<n>` entry in `ROADMAP`
Chest, Storage Chest, Buffer Chest	Silo (solids), Tank (fluids and gases)	Canonical §7 deprecates the word entirely
ChestMode	StorageRole	Same rename
`STORE` (StorageRole value)	`DEPOSIT`	`GENERAL` and `STORE` both read as the broad role, which is what `UNASSIGNED` means
`GENERAL` (StorageRole value)	`DEPOSIT`	Superseded before implementation
Organic carbon, bio-polymer crops	`wood` or `algae`	Both duplicated a substance that already existed
Fast-growth timber	`wood`	Same duplication
`raw_biomass`	`raw_wood`	✅ Applied 2026-08-30 (OI-286). It was named at the category level rather than the substance level. `biomass` is the family; `wood` is the substance. Whether algae joins that family is OI-262
Solar Collector	Solar Panel	One building, two names. Solar Panel wins: 13 documents to 6, and `solar_panel.tres` ships
Shaft, generic Shaft, `PLACE_SHAFT`	Item Lift, Fluid Riser, Power Conduit	Container-plus-contents is replaced by three specific structures
Splitter, Merger, Filter Splitter	Router	Collapsed into one building
IoConnector, PipeConnector	Port	Replaced by configurable ports on the base
Tier, `ResourceTier`	`substance` and `phase`	Conflated production depth with transport medium, so some resources could not be described
Form (as a stored field)	`phase`	A stored form would be a denormalised copy of phase — the same mistake tier made
Medium (as a resource property)	`phase`	Medium describes the mechanism, not the resource
Module Expansion (research node)	Module Technology	Slots are not researched
Module stacking, stack order	(nothing — removed)	Modules sit in fixed roof slots and do not stack
Cel-shader, outline pass	(nothing — removed)	Style is PBR plus emission mask
Category accent colour	(nothing — removed)	Buildings are distinguished by silhouette
Factory Overview (`F`)	Right flap tabs	Removed in `09_UI-UX` v0.6
Session (meaning the whole playthrough)	World	The word was doing two jobs. A session is one sitting; a world is the save. See §0
Control tether	Command range	Did not say what range it referred to
Dead in the water, adrift-as-idiom	Adrift	Nautical. There is no water.
Towed	Recovered	Nautical
Armour efficiency, design efficiency, overall rating	(nothing — forbidden)	Armour has no output, so no denominator exists. A single design score is rankable and destroys creative variety. See §4c
APR as a probability input	APR as a rate	The win-probability formula is removed; APR is ships destroyed per tick and supply consumed per tick

Words that are still fine but often confused: tier remains correct for research tiers and alien tiers. It is only deprecated as a resource field.

6. Schema — as it exists today¶

Recorded so the gap between current code and the decided model is visible. This is the current state, not the target.

`ResourceDefinition`¶

Field	Type	Notes
`id`	`String`	Stable handle. Referenced by recipes and save files.
`display_name`	`String`
`category`	`StringName`	The family. Optional — populated only where substances are interchangeable in recipes. Empty on all five components.
`substance`	`StringName`	What it is specifically.
`type`	`Type`	`RAW` / `REFINED` / `COMPONENT`.
`phase`	`Phase`	`SOLID` / `LIQUID` / `GAS`. Determines transport.

`FluidDefinition`¶

Separate class from ResourceDefinition, joined only by a shared id. Nothing enforces that a fluid resource has one — this is how Chemical Gas ended up with no fluid properties (OI-277).

Field	Type	Notes
`id`	`String`
`display_name`	`String`
`viscosity`	`float`	0.1 thin to 1.0 thick. Currently unread (OI-283).
`density`	`float`	Currently unread (OI-283).
`flammable`	`bool`
`min_temp` / `max_temp` / `base_temp`	`float`
`colour`	`Color`

`BuildingDefinition`¶

Field	Type	Notes
`id`, `display_name`	`String`
`category`	`BuildingCategory`	No Environmental or Waste value exists (OI-017).
`grid_size`	`Vector2i`	Footprint. Determines port count per face and module slot count. Some values disagree with the docs (OI-256).
`model_scene`	`PackedScene`
`base_color`	`Color`	⚠️ Category colour-coding is removed from design.
`power_draw`, `power_output`	`float`	Read by nothing; power is unsimulated.
`max_input_slots`, `max_output_slots`	`int`	⚠️ To be deleted (OI-301). Ports replace them: any port can be `INPUT` or `OUTPUT` and port count derives from footprint.
`inventory_capacity`	`int`
`accepted_recipe_ids`	`Array[String]`	Resolved against `RecipeRegistry` at runtime.
`output_resource_id`	`String`	For non-recipe producers.
`production_ticks`	`int`
`fluid_output_id`	`String`
`fluid_output_pressure`	`float`
`behaviour_script`	`Script`
`base_module_slots`	`int`	⚠️ Design derives slots from footprint + Machine Mk. Relationship to this field undecided.

`RecipeDefinition`¶

Field	Type	Notes
`id`	`String`
`inputs`	`Dictionary`	`resource_id → count`. ⚠️ Item-only. No building can consume a fluid as a production input (OI-001).
`output_resource_id`	`String`	Single output.
`output_amount`	`int`
`production_ticks`	`int`

8. Revision History¶

Version	Date	Changes
0.11	2026-09-13	Ship economy vocabulary defined: Block (a design version — ⚠️ never "Mk", which is a building concept per Canonical §4), refit, decommission, the salvage rule that prices both, and wreck (ship) as distinct from a building wreck, since a building is restored in place and a ship must be gone and got.
0.10	2026-09-11	Cylinder and the ambient rule defined, following `41_Fluid Packaging & Carriage Design` v0.2. The container family is picked by state at ambient (solid rides as an item, liquid in a barrel, gas in a cylinder), which makes the answer unique by construction; the cylinder is the family that tiers, its rungs widening temperature range. ⚠️ Cylinder rungs are named, never "Mk" — Mk is a building concept per Canonical §4 and a container is an item, which would have been the fourth word in this vault doing two jobs. Two stale OI-272 rows in §7 replaced, that item having closed.
0.9	2026-09-05	Phase values corrected. The seam is war, not the planet surface: Phase 1 is everything except war, Phase 2 is war. Three releases across two phases, and both the Launch release and the Space Update are Phase 1. `Phase:` field values updated accordingly.
0.8	2026-09-05	The `Phase:` field convention recorded in §0a, applied across all 47 design documents. Four permitted values; a document spanning more than one says which part goes where.
0.7	2026-09-05	§0b Multiplayer Vocabulary added, closing OI-355. Multiplayer is the umbrella; co-op (more than one account in one world) ships in Phase 1, war multiplayer (many worlds into one war instance) ships in the War Update. Bare multiplayer deprecated where the form matters.
0.6	2026-09-05	§0a Phase Vocabulary added. The word phase runs on two unrelated axes: release phase (two, owned by `02_Scope`) and development phase (the build order, owned by `ROADMAP`, whose `M<phase>.<n>` IDs are an interface and are never renumbered). Bare Phase N deprecated, along with milestone meaning a progression beat, which is now beat.
\1 §0 Scope Vocabulary added — world, session, account, planet, war — resolving the overloaded word session, which had meant both a sitting and a whole playthrough. §4b War Vocabulary and §4c Measurement Vocabulary added. Six deprecations recorded, including control tether, the nautical idioms, and armour efficiency.
0.4	2026-08-29	Lossy loop added, pointing at the new Canonical §12b.
0.3	2026-08-29	Storage vocabulary: Silo holds one substance, capacity in units, Tank mirrors it, packing station and packing module added, and buffer distinguished from storage. `unit_size` added. §6 schema updated now `ResourceTier` is actually gone.
0.2	2026-08-28	`category`, `substance`, `type` and `fuel_value` added. Wood and Algae un-deprecated — they are substances in category `biomass`; `raw_biomass` is deprecated instead, being named at the category level.
0.1	2026-08-28	Initial draft. Resource, building, transport and storage vocabulary; deprecated word list with replacements; current schema for the four definition classes; undefined terms listed against their open items.
0.3	2026-08-29	Added §4a Power Vocabulary: PU against PU·s, grid, connection against reach, shed, brownout, CER. The PU/PU·s split is recorded because the vault had already made that error once, describing accumulator storage as a rate.
