[JFrusher]

This releases 0.5.0: everything on develop since 0.4.0.

• PR #5: the walkable Oberon-class control room. It brings crewed job stations with 2.5D instruments, crew orders and the order wheel, captions for every voice, H.P. air, the GIUK attack plot, and the coxswain's First Watch training.
• PR #6: the sonarman goes for the loudest trace when nothing is in his cone, and the version is bumped to 0.5.0.

Both PRs passed CI and CodeRabbit before merging into develop. Once this merges, I'll tag v0.5.0 on main and publish the GitHub release with notes.

📝 Summary

Summary by CodeRabbit

• New Features

  • Added an explorable 3D submarine control room, with walkable stations, interactive controls and a periscope.
  • Added crew orders, acknowledgements and reports, plus a radial order menu.
  • Added sound captions with speaker attribution and new klaxon alerts.
  • Added high-pressure air management: blowing ballast and firing torpedoes now consume air, which recharges while snorkelling.
  • Added First Watch training across six chapters, with later drills unlocked after completion.
  • Added station-focused console views and refreshed control-room and training guidance.

• Bug Fixes

  • Manual rudder control now cancels standing helm orders.

Walkthrough

The update adds a walkable 3D control room, station-specific controls, crew orders, captions and high-pressure air mechanics. It also revises training, adds a GLB model pipeline, updates packaging and headless checks, and changes the project version to 0.5.0.

Merge Risk

Merge Risk: 🟡 Moderate · up to 24080

Patrols now depend on OpenGL 3.3 and have no fallback. On machines without a usable OpenGL context, a patrol stops as soon as the control room opens. The on-foot attack plot also rebuilds an expensive texture twice per second, which can cause stutter. Handle context failure before release.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 24080

Most changed controls remain within the local game session. However, an installed third-party model can reference image files outside its directory, giving imported data broader filesystem access than its placement suggests. This requires adopting a replacement model; no remote attack endpoint or privilege escalation was established. Security coverage remains incomplete.

Retained concerns

• Low · security · observed: The new replacement-model loader passes model-controlled image URIs to pygame.image.load without restricting them to the model or asset directory. Absolute paths and parent traversal can therefore select user-readable images outside that directory. This is reachable through the documented third-party model replacement mechanism, not just arbitrary Python calls. Generated assets embed their textures, and no outbound disclosure or privilege escalation was established; exposure requires installing a replacement model.

Security review details

Security Blast Radius

• inferred — The established imported-model exposure is the adopting player's process and its user-readable image files. A model author controls texture references after the user installs a replacement. No remote game endpoint, elevated privilege, cross-tenant access, or outbound disclosure was established. Windows network-share behavior remains unverified.

Security Findings and Attack Paths

• observed — The newly introduced path is third-party GLB adoption, preservation by build_all, automatic renderer loading, and model-selected image decoding. Rejecting external binary buffers does not protect the separate image-URI path. Image lookup or decode errors can propagate out of renderer construction.

Trust Boundaries and Controls

• observed — Normal generated models embed textures and runtime model filenames come from application-defined mappings. These constrain ordinary assets but do not validate replacement-model provenance or confine image references. Crew-command authority remains local and passes through Console action checks.

Resilience and Maintainability Implications

• observed — Crew state is created with each Console, and retry creates a fresh session. Replay viewing uses a separate ReplayView rather than restoring pending crew commands. This bounds delayed-command state to a local session rather than a persistent authority transition.

Hardening Proposals

• proposed — For replacement models, require embedded textures or resolve external images beneath an explicitly allowed asset root, rejecting absolute and network-share paths. Consider bounded texture and mesh sizes, cycle detection, and per-model failure recovery so imported data cannot unnecessarily terminate the game.

Then bounce through the room with a proud little jig!}

Cache the tracing-paper surface by size.

OnFoot.draw refreshes plot_art every 0.5 seconds of simulation time. Each refresh calls art.texture for the 1040×720 paper. The paper depends only on size and its fixed texture parameters. Cache it to avoid repeating this expensive operation.

moderngl create_standalone_context require=330 macOS core profile default version

💡 Result:

`require=330` means **OpenGL 3.3 is the minimum**, not that ModernGL will create exactly version 3.3. Check `ctx.version_code` for the actual version returned. ([moderngl.readthedocs.io](https://moderngl.readthedocs.io/en/latest/topics/context.html?utm_source=openai))

```python
ctx = moderngl.create_standalone_context(require=330)
print(ctx.version_code)
```

On macOS, Apple’s native OpenGL profiles are core profiles; Apple documents 3.2 core and 4.1 core profile options. So 3.3 is within that range, but the exact version you get depends on the backend and machine. ([developer.apple.com](https://developer.apple.com/documentation/appkit/opengl-profiles?utm_source=openai))

If you mean “what is the default when I omit `require`?”: ModernGL’s documented minimum is **330 (OpenGL 3.3)**. That’s a minimum request, not a fixed default context version. ([moderngl.readthedocs.io](https://moderngl.readthedocs.io/en/latest/topics/context.html?utm_source=openai))

Handle OpenGL context failure at the patrol boundary.

OnFoot.draw can create a context through graphics.instruments._gl() while composing station screens. It then creates another context through App.room(). If either operation fails, the process-level handler only logs the traceback and re-raises, so the patrol terminates.

Catch the context-creation failure around the on-foot rendering path. Leave on-foot mode and use the full console only if that path does not use OpenGL. Do not use require=330 as the failure fix; ModernGL already documents OpenGL 3.3 as the minimum when the argument is omitted.

Isolate direct tutorial-test settings writes.

tests/test_tutorial.py completes FIRST WATCH and can call settings.save() through Tutorial.advance(). Direct execution can therefore write trained=True to the user's settings file. checks.py already uses a temporary HOME, so uv run checks.py is isolated. Patch settings.save in tests/test_tutorial.py, or set HOME and USERPROFILE to a temporary directory before importing settings.
