format & persistence, server authority + client +> prediction, content moderation & age verification, avatar component system +> **Godot version:** 4.6.2 stable + +## 1. Overview + +This document evaluates the two primary ways to build the **world/level +authoring tool** for **agp-game**: + +- **(a) Godot editor plugin** — extend the Godot editor itself with custom + panels, dock widgets, and tools that operate on the project's scenes and + resources. +- **(b) In-game editor** — a fully custom editor built as game UI (Godot + `Control` nodes) that runs inside the running game, editing the game's own + world data. + +The goal is to pick the approach that best fits the platform's constraints: +a **server-authoritative** multiplayer game where the **world is stored as +versioned chunks** (see `world.md`), content is **moderation-flagged** (see +`content_moderation.md`), and the client is a **shipped binary** that players +run (not a dev tool). + +This document is a **decision record**: it lays out the trade-offs, gives a +clear recommendation, and defines the resulting architecture boundaries. + +--- + +## 2. Context & Constraints + +Before comparing the two approaches, we must fix the constraints that drive the +decision. These come from the existing architecture docs. + +### 2.1 The World Is Data, Not Scenes + +`world.md` defines the world as **chunk data** (JSON for authoring, binary for +runtime/network), persisted in SQLite on the server. A chunk is the atomic unit +of load, save, and stream. The **server is the only writer** to the store; +clients submit **deltas** against a `base_revision` and the server validates and +applies them. + +**Implication:** The editor's output is **chunk payloads**, not `.tscn` scene +files. Whatever editor we build must serialize to the chunk contract, not to +Godot scene resources. + +### 2.2 Server-Authoritative & Moderation-Aware + +- The server validates every edit (schema, bounds, moderation) before + persisting (`world.md` §5.4). +- Content carries **content flags** aggregated from referenced assets/scripts + (`content_moderation.md` §3). Mature content is gated behind age verification. +- The client receives a **content manifest** and never loads content not in it. + +**Implication:** An editor that runs on a **player's machine** cannot be the +authority on what gets published. Editing must go through the server's +validation pipeline, and the editor must surface moderation flags. + +### 2.3 The Client Is a Shipped Binary + +The game is a multiplayer product. Players run a **release build**. The Godot +editor is a **development tool** that players do not have. + +**Implication:** If authoring is a first-class *player* feature (user-generated +content), the editor must ship inside the game binary. If authoring is a +*developer/platform* feature, it can live in the editor. + +### 2.4 Two Distinct Audiences + +The evaluation must separate two audiences, because they have opposite needs: + +| Audience | Who | Where they run | What they build | +|----------|-----|----------------|-----------------| +| **Platform/dev** | The team building the game | Godot editor (dev machines) | Base worlds, rooms, templates, test levels | +| **Players (UGC)** | End users | The shipped game | Their own rooms/worlds, published to the server | + +The two approaches map cleanly onto these audiences, and the right answer is +likely **both** — but with a clear primary recommendation. + +--- + +## 3. Approach (a): Godot Editor Plugin + +### 3.1 What It Is + +A Godot editor plugin is a set of scripts (and optionally scenes) that extend +the editor via the `EditorPlugin` API. It can add: + +- **Dock panels** (`add_control_to_dock`) — e.g., a chunk/tile palette panel. +- **Toolbar buttons** (`add_control_to_container`). +- **Inspector plugins** (`EditorInspectorPlugin`) — custom property editors. +- **Import plugins** (`EditorImportPlugin`) — custom asset importers. +- **Scene/Node plugins** (`EditorNode3DGizmoPlugin`) — custom gizmos. +- **Menu entries** (`add_tool_menu_item`). + +Plugins are enabled per-project via `project.godot` (`[editor_plugins]`). + +### 3.2 Pros + +- **Full editor power for free:** You get the scene tree, inspector, viewport + navigation, undo/redo, gizmos, and asset pipeline — all battle-tested. +- **Native Godot editing:** Editing `.tscn` scenes, materials, and nodes is + exactly what the editor is built for. Great for authoring **base content** + (rooms, templates, avatar base bodies). +- **Fast iteration for devs:** The platform team can build and test levels + directly in the tool they already use. +- **Undo/redo, selection, snapping** come from the editor's `EditorUndoRedoManager`. +- **No runtime footprint:** Editor-only code is stripped from export builds + (`@tool` scripts and editor plugins are not shipped to players). + +### 3.3 Cons + +- **Not available to players.** Players don't run the Godot editor. Any + player-facing UGC authoring cannot use this approach. +- **Tied to the editor's UX.** You inherit the editor's look and interaction + model; deep customization is limited by what the editor API exposes. +- **Editor API churn.** `EditorPlugin` APIs change between Godot versions; + plugins are more brittle across upgrades than game code. +- **Scene-centric, not data-centric.** The editor is optimized for scenes and + resources. Our world is **chunk data** (`world.md`). We'd have to build a + translation layer (scene ↔ chunk) and keep it in sync — a real source of + drift. +- **Single-user, local.** The editor edits local files. It does not natively + talk to our server-authoritative chunk store or the moderation pipeline. +- **Headless/CI friction.** Validating plugin behavior in CI requires running + the editor headless, which is heavier than testing game code. + +### 3.4 Fit for Our Constraints + +- **Platform/dev authoring:** Excellent. This is the natural home for building + base worlds, rooms, and templates. +- **Player UGC:** Not applicable. Players cannot run the editor. +- **Server-authoritative chunk store:** Poor fit natively. The editor edits + local scenes; we'd bolt on a chunk export/import and a server sync layer. + +--- + +## 4. Approach (b): In-Game Editor + +### 4.1 What It Is + +A fully custom editor built as **game UI** — Godot `Control` nodes (panels, +buttons, toolbars) that run inside the running game. It edits the game's own +world data model (chunks) and submits edits through the normal server pipeline. + +### 4.2 Pros + +- **Ships to players.** The editor is part of the game binary, so **player UGC + authoring is possible** — the core requirement for a user-generated-content + platform. +- **Data-native.** The editor operates directly on the **chunk model** + (`world.md`), so there is no scene↔chunk translation layer and no drift. +- **Server-authoritative by construction.** Edits go through the same + `request_chunk_edit` RPCs as gameplay, so validation, revisioning, and + moderation apply uniformly. The editor cannot bypass the server. +- **Moderation-aware.** Because edits flow through the server, content flags are + computed and enforced at the boundary (`content_moderation.md` §4). The editor + can surface flags and gate mature content. +- **One codebase, one UX.** The editor uses the same UI toolkit and art style as + the game; no separate editor theme to maintain. +- **Testable in CI.** The editor is ordinary game code; it can be exercised + headlessly and unit-tested like any other system. + +### 4.3 Cons + +- **We build everything.** No free scene tree, inspector, gizmos, or undo/redo. + We must implement selection, snapping, undo/redo, viewport navigation, and + property editing ourselves. +- **Runtime footprint.** Editor UI ships in the binary (though it can be gated + behind a feature flag / separate scene that is only instantiated on demand). +- **More upfront work.** A usable in-game editor is a large feature; it needs + its own architecture (tool modes, gizmos, palette, inspector). +- **Not ideal for deep asset authoring.** Modeling a mesh or authoring a + material is better done in the Godot editor / DCC tools. The in-game editor + should focus on **world composition** (placing tiles and objects), not asset + creation. + +### 4.4 Fit for Our Constraints + +- **Platform/dev authoring:** Workable but not ideal for deep asset work. +- **Player UGC:** The **only** viable approach. Players can only author through + the shipped game. +- **Server-authoritative chunk store:** Excellent fit. The editor is a client + that submits validated deltas. + +--- + +## 5. Comparison Matrix + +| Criterion | (a) Editor plugin | (b) In-game editor | +|-----------|-------------------|--------------------| +| Ships to players | ❌ No | ✅ Yes | +| Player UGC authoring | ❌ Impossible | ✅ Core capability | +| World data model fit | ⚠️ Scene-centric; needs translation layer | ✅ Chunk-native | +| Server-authoritative edits | ⚠️ Bolted on | ✅ Native (same RPCs) | +| Moderation enforcement | ⚠️ Manual | ✅ At the boundary | +| Free editor features (undo, gizmos, inspector) | ✅ Rich | ❌ Build ourselves | +| Runtime footprint | ✅ None (stripped from export) | ⚠️ Ships in binary (gated) | +| Dev iteration speed | ✅ Fast | ⚠️ Slower to build | +| Deep asset authoring (mesh/material) | ✅ Native | ❌ Out of scope | +| CI testability | ⚠️ Heavier (headless editor) | ✅ Ordinary game code | +| Editor API churn risk | ⚠️ Higher | ✅ None (game code) | + +--- + +## 6. Recommendation + +**Primary recommendation: build the in-game editor (b) as the platform's +authoring surface, and use a lightweight Godot editor plugin (a) only as an +internal dev convenience.** + +### 6.1 Rationale + +1. **Player UGC is the deciding factor.** The platform's value proposition is + user-generated content (rooms, worlds, avatars). Players cannot run the Godot + editor, so **only an in-game editor can deliver player authoring**. This is a + hard requirement that the editor-plugin approach cannot meet. + +2. **The world is data, and the in-game editor is data-native.** `world.md` + defines chunks as the atomic unit. An in-game editor edits chunks directly + and submits them through the server pipeline. An editor plugin would force a + scene↔chunk translation layer that is a constant source of drift and bugs. + +3. **Server authority and moderation fall out naturally.** Because in-game + edits use the same `request_chunk_edit` RPCs as gameplay, validation, + revisioning, optimistic concurrency, and content-flag enforcement + (`content_moderation.md`) apply uniformly. The editor cannot bypass the + server — which is exactly what a moderation-aware UGC platform needs. + +4. **The editor-plugin's strengths are not what we need.** Its free features + (scene tree, inspector, gizmos) are for editing Godot scenes and resources. + Our authoring is world composition against a chunk contract, not scene + editing. The plugin's main win — deep asset authoring — is better served by + DCC tools and the Godot editor for the *platform team*, not by a plugin we + must maintain. + +### 6.2 The Role of the Editor Plugin (Dev Convenience Only) + +We still recommend a **small, optional** editor plugin for the **platform team** +to author **base content** (base rooms, templates, avatar base bodies, test +levels) directly in the Godot editor. This is a dev-time convenience, not a +product feature: + +- It can export a scene/resource as a **chunk** (reusing the same encoder as the + in-game editor) so dev-authored content flows into the same pipeline. +- It is **not shipped** to players and is **not** the authoring surface for UGC. +- It should be kept thin to minimize editor-API churn risk. + +### 6.3 Scope Boundary + +To keep the in-game editor tractable, define its scope clearly: + +- **In scope (world composition):** placing tiles, placing static/dynamic + objects, setting transforms, editing object properties, saving/loading chunks, + submitting edits to the server, showing moderation flags. +- **Out of scope (asset creation):** modeling meshes, authoring materials, + rigging avatars. These are done in DCC tools / the Godot editor and imported + as catalog assets (see `avatar.md` §7). The in-game editor **references** + catalog assets by id; it does not create them. + +--- + +## 7. Resulting Architecture + +### 7.1 Shared Editor Core + +Both the in-game editor and the (optional) dev plugin should share a single +**editor core** that operates on the chunk model.

Removing that garbage and bringing over the real project from agent/997c429bc6b4 (the original PR's branch) with the review feedback addressed: - Play button no longer references the nonexistent scenes/game.tscn. - Wired PlayButton/QuitButton [connection] entries in main_menu.tscn. - Removed the invalid uid="uid://main_menu". - Added .gitignore for .godot/. - Removed the non-standard [export]/[export_options] sections from project.godot (Godot 4 uses export_presets.cfg, not this). --- .gitignore | 2 + addons/.gitkeep | 0 assets/.gitkeep | 0 .../app/__pycache__/__init__.cpython-312.pyc | Bin 161 -> 0 bytes .../app/__pycache__/config.cpython-312.pyc | Bin 2053 -> 0 bytes .../app/__pycache__/database.cpython-312.pyc | Bin 1602 -> 0 bytes .../__pycache__/dependencies.cpython-312.pyc | Bin 2357 -> 0 bytes backend/app/__pycache__/main.cpython-312.pyc | Bin 1934 -> 0 bytes .../__pycache__/__init__.cpython-312.pyc | Bin 404 -> 0 bytes .../models/__pycache__/asset.cpython-312.pyc | Bin 2259 -> 0 bytes .../__pycache__/session.cpython-312.pyc | Bin 1638 -> 0 bytes .../models/__pycache__/user.cpython-312.pyc | Bin 1482 -> 0 bytes .../models/__pycache__/world.cpython-312.pyc | Bin 1869 -> 0 bytes .../__pycache__/__init__.cpython-312.pyc | Bin 169 -> 0 bytes .../__pycache__/assets.cpython-312.pyc | Bin 8664 -> 0 bytes .../routers/__pycache__/auth.cpython-312.pyc | Bin 6650 -> 0 bytes .../routers/__pycache__/users.cpython-312.pyc | Bin 6194 -> 0 bytes .../__pycache__/worlds.cpython-312.pyc | Bin 7588 -> 0 bytes project.godot | 24 ++++++++++ scenes/.gitkeep | 0 scenes/main_menu.tscn | 43 ++++++++++++++++++ scripts/.gitkeep | 0 scripts/main_menu.gd | 14 ++++++ 23 files changed, 83 insertions(+) create mode 100644 .gitignore create mode 100644 addons/.gitkeep create mode 100644 assets/.gitkeep delete mode 100644 backend/app/__pycache__/__init__.cpython-312.pyc delete mode 100644 backend/app/__pycache__/config.cpython-312.pyc delete mode 100644 backend/app/__pycache__/database.cpython-312.pyc delete mode 100644 backend/app/__pycache__/dependencies.cpython-312.pyc delete mode 100644 backend/app/__pycache__/main.cpython-312.pyc delete mode 100644 backend/app/models/__pycache__/__init__.cpython-312.pyc delete mode 100644 backend/app/models/__pycache__/asset.cpython-312.pyc delete mode 100644 backend/app/models/__pycache__/session.cpython-312.pyc delete mode 100644 backend/app/models/__pycache__/user.cpython-312.pyc delete mode 100644 backend/app/models/__pycache__/world.cpython-312.pyc delete mode 100644 backend/app/routers/__pycache__/__init__.cpython-312.pyc delete mode 100644 backend/app/routers/__pycache__/assets.cpython-312.pyc delete mode 100644 backend/app/routers/__pycache__/auth.cpython-312.pyc delete mode 100644 backend/app/routers/__pycache__/users.cpython-312.pyc delete mode 100644 backend/app/routers/__pycache__/worlds.cpython-312.pyc create mode 100644 project.godot create mode 100644 scenes/.gitkeep create mode 100644 scenes/main_menu.tscn create mode 100644 scripts/.gitkeep create mode 100644 scripts/main_menu.gd diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..dd2198a --- /dev/null +++ b/.gitignore @@ -0,0 +1,2 @@ +# Godot 4 editor cache/import directory +.godot/ diff --git a/addons/.gitkeep b/addons/.gitkeep new file mode 100644 index 0000000..e69de29 diff --git a/assets/.gitkeep b/assets/.gitkeep new file mode 100644 index 0000000..e69de29 diff --git a/backend/app/__pycache__/__init__.cpython-312.pyc b/backend/app/__pycache__/__init__.cpython-312.pyc deleted file mode 100644 index b85585fd2c6b5543383cf26a2c5bdf4bf171f920..0000000000000000000000000000000000000000 GIT binary patch literal 0 HcmV?d00001 literal 161 zcmX@j%ge<81eXe%vq1D?5P=Rpvj9b=GgLBYGWxA#C}INgK7-W!a?sDn&rQ`&NlZzp z)K5$=&@ay~$}TQQOitBL&QD1#icdB%G&N67PSa0HOwLZtOVLj(DA13O&&nC&o diff --git a/backend/app/__pycache__/config.cpython-312.pyc b/backend/app/__pycache__/config.cpython-312.pyc deleted file mode 100644 index 9d3ececc84f0f5be6e00fe24657d911d793df2e7..0000000000000000000000000000000000000000 GIT binary patch literal 0 HcmV?d00001 literal 2053 zcmZWqO>7fK6rNqL{}Lx5e-0!xI7Mw`fq#G`gcL;BQ$=sB=&iS&dhaC=sibqFs;Y`xAi0!N-;C`L#7g_-eeb<_Gw;oN zGrzaBwIKMO-nzf`tAxM%zsp%!IE9Us-muvs7OPTibDzw6WZ0}rntYf zuDWVtS9~~(l>*#C1jz!#D=tHnvWG~-tBIFEqj_W>M-oR~*-rwX^Ks;tgIpKjC@8mZ z)WT7#+{#giqc%CjQ9DN+avNy}FUL6QlsmYti=%G&7)L!E^~#;xGRzQUu1o9Fj%(hZ zPaNjEoAhY?q?br1zyfkTa3t5^^^?)}XrP&iYHMnGF*2#BH;JLqKx%Oj=Th^Tsy7)w z7f;ewCioTOVpdrOfFAXuUMwz7H#6(DxFcBbwjm^jMQilLe1nB&?|1hl1)naXFD@NDK&>b+JtKQc;#sk!Ne ze0J&D{EI=z1|3LEO=SuNytFWz$>GfP#cV!<=d-!xrA(oEX4Q4Aw>C1C97~>kM|vTd zOw!QQLcV~(_jEQ_p#F+gG8N6CEz65@3#l|tXY(&KwqnN;)+3t1Ufo2*K4V%)BJ zEAC2cEb5^FKzKzj5!%`0Ffmk9V?nj6P{Y_EhNHXsZ9;uEaVxf=3gEo?vC3uLwqFIZ zh3=xYrsl}F*67D0BB<=g4L@o0wV;Ycq>7(+A#_i;E37s9;mCw$mwqFD)gyuJJ)r

Overview + +This document evaluates how to safely run **user-written scripts** as part of +UGC (user-generated content) in **agp-game**, and recommends an approach. + +**Bottom line: Godot 4 has no built-in security sandbox for GDScript, and +none of the three options named in the original task hold up under testing.** +A script running anywhere inside the Godot process — however it's loaded, +parented, or wrapped — runs with full engine privileges: arbitrary process +execution, full filesystem read/write, and raw network access. Sandboxing +has to happen *outside* the scripting language, not through an in-engine +restriction mechanism, because no such mechanism exists. + +This was verified directly against Godot 4.6.2 (`godot --headless`, evidence +in `sandbox_probe/` on this branch) rather than assumed from documentation, +some of which (see §2.1) describes APIs that don't actually exist in this +version. + +## 2. Options Evaluated + +### 2.1 Godot's built-in "ScriptServer" restrictions — does not exist + +There is no `ScriptServer` class in Godot 4.6.2: + +``` +ClassDB.class_exists("ScriptServer") → false +``` + +There's also no project setting to disable engine subsystems for scripts — +none of `application/run/disable_os`, `disable_file_access`, or +`disable_network` exist as settings, and `ProjectSettings.get_property_list()` +returns nothing matching "sandbox", "restrict", or "security". Any plan that +assumes a flag like this exists needs to be dropped; it was likely conflated +with sandboxing features from a different engine/scripting ecosystem, or +with **export template stripping** (which controls what ships in a build, +not what a script can call at runtime). + +Directly probed capabilities of an ordinary GDScript running as a normal +node script, no special setup: + +| Capability | Available to any script? | +|---|---| +| `OS.execute(...)` — run arbitrary processes | ✅ Yes | +| `FileAccess.open(...)` — read/write any path the OS user can reach | ✅ Yes (read `/etc/hostname`, write `/tmp/...` both succeeded) | +| `TCPServer` / `HTTPClient` / `HTTPRequest` / `PacketPeerUDP` / `WebSocketPeer` | ✅ All instantiate and work | +| `ClassDB.instantiate(...)` — construct any engine class by name | ✅ Yes | +| Loading and running a second script from source text at runtime (`GDScript.new()` + `.reload()`) | ✅ Yes | + +**Verdict: rejected.** There is nothing to configure here — the restriction +surface this option assumed doesn't exist in the engine. + +### 2.2 Isolated SubViewport with a limited API — doesn't isolate scripts + +`SubViewport` is a **rendering and input isolation** primitive (it gives a +scene subtree its own render target and can gate input propagation) — it is +not a security or scripting boundary. A script attached to any node inside a +`SubViewport` still runs in the same process, on the same GDScript VM, with +the exact same access to `OS`, `FileAccess`, networking classes, and +`ClassDB` as a script anywhere else in the tree. Nothing about being +"inside" a SubViewport changes what API calls are reachable from a script. + +**Verdict: rejected.** This solves a rendering/UI-composition problem, not +the security problem the task is asking about. Worth keeping in mind for +other purposes (e.g. isolated preview rendering of user avatars), but it +provides zero script sandboxing. + +### 2.3 Custom GDScript interpreter with an allowlist — right idea, wrong layer for "custom interpreter" + +Two ways to read this option, tested separately: + +**(a) Write/embed a separate GDScript parser+interpreter.** Not +practical — this means re-implementing (and then indefinitely maintaining, +in lockstep with every Godot release) a full language interpreter outside +the engine. Far more engineering than the problem justifies. + +**(b) Use Godot's built-in `Expression` class as a restricted subset.** +`Expression` *looks* like a natural allowlist mechanism — it only evaluates +a single expression, no control flow, no arbitrary statements. But it isn't +safe by default: it can still reach through to unsafe engine methods if you +aren't careful about what object you hand it as a base instance: + +```gdscript +var expr = Expression.new() +expr.parse("get_environment('HOME')", ["OS"]) +expr.execute([], OS) # → "/home/daddy" (successfully called OS.get_environment) +``` + +So `Expression` is a viable building block only if the host **never passes +a base instance (or arguments) that exposes anything sensitive** — i.e. the +allowlisting work still has to happen at the call site, `Expression` itself +enforces none of it. + +**Static text pattern-matching (blocklisting dangerous substrings like +`"OS.execute"` before parsing) was also probed and is not a real +defense** — it's trivially defeated by string concatenation, `call()`, +`Callable`, or any other indirection, and produces false confidence. + +**Verdict: partially viable, but only as a foundation, not a solution on +its own.** A hand-built, narrow, data-driven DSL (not full GDScript, not +raw `Expression`) with an explicit allowlist of safe operations and *no +ability to reference engine singletons or arbitrary objects* is the only +version of "custom interpreter" that's actually safe. This is real +engineering effort, not a config flag. + +## 3. Recommendation + +**Don't run untrusted GDScript in-process at all.** Given none of the three +in-engine options provide a real boundary, the two approaches actually worth +building are, in order of recommended priority: + +1. **Primary: a narrow, non-Turing-complete content DSL**, not general + scripting. Most UGC scripting needs in a game like this (custom + interactions, simple triggers, item behaviors) don't need a general + programming language — they need a small set of declarative + verbs/conditions (e.g. `on_interact: give_item("torch")`, + `on_enter: play_sound("chime")`). Expressed as data (JSON/Resource, not + code) and interpreted by trusted, hand-written GDScript on the engine + side. This has *zero* attack surface by construction — there's no + interpreter to escape because there's no general execution, just a + fixed, reviewed set of verbs. This is almost certainly sufficient for + the actual UGC use cases in this game and should be scoped against real + feature requirements before assuming more is needed. + +2. **If genuinely general scripting becomes a hard requirement**, isolate it + at the OS level, not the engine level: run untrusted scripts in a + **separate process** (a stripped-down Godot instance or a dedicated + interpreter) under OS sandboxing (a restricted user account, a + container, or `firejail`/`bwrap`/seccomp), communicating with the main + game over a narrow IPC/RPC boundary that only exposes intentionally-safe + operations. This is the only approach that provides a real security + boundary for arbitrary code, because it doesn't depend on the scripting + language cooperating — the OS enforces it. Substantially more + infrastructure than option 1; only worth it if option 1's DSL genuinely + can't express what's needed. + +**Do not** attempt in-process GDScript sandboxing via SubViewport, +ScriptServer, or ad hoc blocklisting — all three were directly tested and +none provide a real boundary (§2). + +## 4. Open Questions + +- What do actual planned UGC scripts need to *do*? (Trigger conditions, + simple item/state effects, dialogue branching?) This determines whether + the DSL in §3.1 is sufficient or whether §3.2's process isolation is + needed. Needs a concrete feature list before implementation starts. +- If §3.2 is needed later, does it run per-user-session or shared/pooled? + Affects resource cost and isolation guarantees. +- Interaction with the content moderation pipeline (`content_moderation.md`): + scripts as a moderated content type still need a moderation flag path + regardless of which execution model is chosen — a DSL makes static + analysis of *what a script can possibly do* far easier than it would be + for general code, which is an additional point in its favor. diff --git a/sandbox_probe/probe_scriptserver_check.gd b/sandbox_probe/probe_scriptserver_check.gd new file mode 100644 index 0000000..b5425c6 --- /dev/null +++ b/sandbox_probe/probe_scriptserver_check.gd @@ -0,0 +1,6 @@ +extends SceneTree +func _init(): + print("ScriptServer class exists: ", ClassDB.class_exists("ScriptServer")) + var sv = SubViewport.new() + print("SubViewport instantiated: ", sv != null) + quit() From 5d7c61029c950bae79d54edaa5d4a0bfc3b846c5 Mon Sep 17 00:00:00 2001 From: coder-bot Date: Tue, 18 Aug 2026 00:14:37 +0000 Subject: [PATCH 54/56] Fix remaining critical review issue: list_worlds visibility filter bypass MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Requesting an explicit ?visibility=PRIVATE (or FRIENDS_ONLY) skipped the ownership check entirely — any authenticated user could list every other user's private worlds just by passing the filter.
