Oiled Up

Where the project is

Milestone	State
M0 Grey box · M2 Verdict loop · M3 Contamination · M5 Day cycle	Complete
M1 Chemistry + tests	Complete bar debug tooling and CI (#3, #18)
M4 Co-op	Complete; not yet played in a real two-instance session
D1 Heat-treatment domain · D2 Deliveries and customers	Complete
F1 Frontend, options, accessibility	Complete
M6 Art · M7 Content and balance · M8 Weird layer	Not started

A single player can play a full contract end to end: samples arrive by truck, are unboxed, reconciled against a delivery note, prepped, run, filed, and resolved — with the run surviving a quit. It remains pre-alpha.

Project

Oiled Up is a 1–4 player first-person co-op game about running a heat-treatment oil laboratory. Receive customer samples, choose and operate tests, interpret the results, and file a verdict before a bad quench bath ruins parts or starts a fire. Unnecessary shutdowns are costly too, so there is no safe default answer.

The project is built with Unity 6 and URP. It currently includes the playable lab workflow, deterministic chemistry, contamination and calibration systems, customer deliveries and note reconciliation, host-authoritative multiplayer, proximity voice, run save and continue, and a full front end.

See docs/DESIGN.md for the full design and technical rules.

Still missing

Verification debt

• Co-op has never been played. Cartons, notes and slips all replicate as of #80, and the host-only boundary is enforced by the reflection sweep in NetworkViewTests — but no two-instance session has actually been run. Build a player, join the Editor, and watch a guest carry a carton in and open it.

• The EditMode suite is not routinely run. #76 fixed the deadlock that made it unrunnable, but that fix is itself unvalidated, and roughly sixty tests added since have never been executed. Run Residue > Build > Run EditMode Tests and read Temp/oiledup-editmode.txt.

• #18 CI is deliberately off while this is a single-developer project — the local path works, it is just operated by hand. Revisit if a second person commits, or if main goes red unnoticed again.

• .meta files are outstanding for the scripts added in the audio, credits and sample-dump commits. Unity was not running when they landed, so it has not imported them yet. Open the Editor and commit the generated .meta files before pushing to another machine.

Polish and accessibility (F1)

• #46 Audio is in but unheard — room tone, per-instrument run-finished chimes, machine loops and interaction feedback all ship, and the volume sliders route. Nobody has actually listened to it yet.
• No language ships but English. #55 made translation possible, not done: ~500 strings now carry ids and named arguments, and a test fails any new literal reaching a draw call. Actually translating is a separate job, and so is the font — the in-world screens raster a pixel font with no glyph coverage past Latin, and a 32-column CRT is its own problem.

Not started

• Art pass (M6), content and balance pass (M7), and the optional weird layer (M8).
• #34 Assemblies and namespaces are still Residue.* from the working title.

Track the details in GitHub Issues.

Requirements

• Git LFS
• Unity Hub
• Unity Editor 6000.5.9f1

Setup

git lfs install
git clone git@github.com:miopowered/OiledUp.git
cd OiledUp
git lfs pull

Add the project in Unity Hub and open it with Unity 6000.5.9f1. After package restore, use these menu commands:

1. Residue > Content > Rebuild Definitions
2. Residue > Content > Validate
3. Residue > Art > Rebuild Palette
4. Residue > Build > Rebuild Greybox Lab

Open Assets/Scenes/Boot.unity and press Play. That is the scene a build starts in, and the menu, the save slot and the lobby all wake up there — opening Lab.unity directly skips them and starts a run with no way back to a menu.

Tests

Residue > Build > Run EditMode Tests, then read Temp/oiledup-editmode.txt. It appends a line per test as the run goes, so a run that dies partway still says how far it got. The Test Runner window works too.

Do not drive TestRunnerApi from the Unity MCP tool — see the trap documented in CLAUDE.md, which deadlocks the Editor after every test has passed.

When changing balance data, edit Assets/Editor/Content/ContentTables.cs, rebuild and validate the definitions, then run the full EditMode suite. Do not edit generated .asset files by hand.

The host owns samples, measurements, machines, economy, and consequences. Clients request interactions and never receive sample ground truth.

• Use one issue per branch and one branch per pull request.
• Commit Unity assets with their .meta files.
• Keep generated content and scene files out of manual YAML edits.
• Preserve the host-only SampleGroundTruth boundary.
• Keep chemistry deterministic and scientifically consistent.
