Recovered orphaned WIP before switching to a new task

Scaffolding only — FastAPI app, SQLAlchemy models, Alembic migrations,
and docker-compose from the original task description are still not
implemented. Committing what exists so it isn't lost; task ec0074121ca3
reset to pending to finish the rest.

-# ModBison (Project & Agent Guidelines)
-
-> **CRITICAL REBRANDING NOTICE**
-> - **Game Name**: **ModBison** (formerly `agp-game`).
->   - "ModBison" represents a play on game modification and the 1960s British "mod" subculture, adhering to the user's "bison" project naming convention (e.g. host machine `cloudbison`, Windows client machine `pinkbison`, social platform `WiseBison`).
-> - **In-Game Currency**: **Buffalo Chips** (formerly `Credits` / `CR`).
->   - Named playfully after bison poop. Displayed throughout all UI menus, wallet, marketplace, and creator payout screens as "Buffalo Chips".
-> - **Git Repository**:
->   - Local clone path: `/home/daddy/modbison` (symlinked as `/home/daddy/agp-game-dev` for backwards compatibility).
->   - Gitea repository name: `modbison`
->   - Clone URL: `http://localhost:3000/daddy/modbison.git`
->   - Web UI: `https://git.cloudbison.duckdns.org/daddy/modbison`
-> - **Binaries & Exports**:
->   - Windows: `modbison.exe` (legacy alias `agp-game.exe` maintained for backwards compatibility)
->   - Linux: `modbison.x86_64`

-
-## 🦬 About ModBison
-
-**ModBison** (formerly `agp-game`) is a collaborative sandbox game and platform built in Godot 4 and Python FastAPI. 
-
-* **The Name**: "ModBison" is a double play on game modification and the 1960s British "mod" youth subculture, aligning with the host and infrastructure naming convention (`cloudbison`, `pinkbison`, `WiseBison`).
-* **The Currency**: **Buffalo Chips** — the in-game virtual currency used for marketplace trading, creator selling, and cash payouts (a playful reference to bison poop).
-
----
-
-## 🏛️ Architecture Overview
-
-The platform consists of two integrated environments:
-
-1. **Client & Game Server (`modbison`)**:
-   - Built with **Godot 4.6.2** (GDScript).
-   - Headless Godot dedicated server (`scenes/server.tscn`) spawned per active world session via high ENet ports.
-   - Dual-platform export configuration: Windows Desktop (`modbison.exe`) and Linux (`modbison.x86_64`).
-   - Binary chunk streaming and client-side interpolation.
-
-2. **Backend & Orchestration Platform (`agp`)**:
-   - **FastAPI** (Python 3.12) REST API with **PostgreSQL** (asyncpg) and **Alembic** migrations.
-   - **Redis** for real-time presence heartbeats and pub/sub messaging.
-   - **Game Server Supervisor**: Dynamic headless Godot instance orchestrator allocating runtime servers in `/tmp/modbison-game-servers`.
-   - **PM Dashboard & Checkpoints**: Live orchestration dashboard running at `http://localhost:7070` managing Package Checkpoints (**PC1** through **PC4**).
-
----
-
-## ✨ What Has Been Built (Feature Summary)
-
-### 1. 👤 3D Avatar & Customization Engine
-* **Canonical Rig**: 24-bone skeleton supporting attachment sockets for Head, Hair, Face, Chest, Pants, Left/Right Hand, Left/Right Foot, and Accessories.
-* **Customization Studio** (`scenes/avatar_customization.tscn`): Full 3D turntable preview, orbit camera controls, slot-based equipment, RGB tint pickers, and backend persistence (`/api/avatar/loadout`).
-* **Multiplayer Replication**: Remote players receive complete avatar loadout dictionaries via RPC upon joining, dynamically assembling meshes and materials in real time.
-* **Solid Double-Sided Rendering**: Fixed polygon winding order and material setups to ensure characters render fully solid from all camera angles.
-
-### 2. 🌍 Multiplayer World & Chunk Streaming
-* **Dedicated Server Architecture**: Server-authoritative player movement, client prediction, reconciliation, and collision boundaries.
-* **Chunk Streaming**: Binary stream encoding/decoding (`chunk_codec.py` / `chunk_data_decoder.gd`) enabling real-time streaming of world geometry, collision boxes, and dynamic props as players explore.
-* **Stable Spawn System**: Server-authoritative solid ground anchoring ensuring players never fall into the void upon connection.
-
-### 3. 🛠️ In-Game World Editor & Sandboxed Scripting
-* **Runtime World Editor** (`scripts/editor/`): In-game tool registry, block/prop palette, selection manager, raycast placement/deletion, and undo/redo action stacks.
-* **Chunk Persistence** (`chunk_save_service.gd`): Saves player modifications and created structures back to the world backend.
-* **Rule-Based Scripting** (`scripts/scripting/`): Sandboxed behavior interpreter (`script_interpreter.gd`, `script_rule.gd`) allowing props to trigger gameplay actions, inventory changes, and spawn events.
-* **In-Game HUD Bar**: Hotkey-driven overlay bar giving players instant access to build tools and menus while inside a live world.
-
-### 4. 👥 Social, Chat & Clans
-* **Friends & Presence** (`scenes/friends_presence_ui.tscn`): Friend requests, accept/decline flows, and live online/in-world presence heartbeats via Redis.
-* **Multi-Channel Chat** (`scenes/chat_ui.tscn`): Direct messaging (DM), group chat, and spatial in-world chat with automated text filtering (`text_filter.py`).
-* **Groups & Clans** (`scenes/groups_ui.tscn`): Group creation, member roles, descriptions, and membership rosters.
-
-### 5. 💰 Virtual Economy & Creator Payouts
-* **In-Game Currency**: **Buffalo Chips** displayed across all menus, wallets, listings, and payout screens.
-* **Wallet UI** (`scenes/wallet_ui.tscn`): Live balance display, quick-purchase packs (+100, +500, +1,000, +5,000 Buffalo Chips), and transaction history ledger.
-* **Marketplace UI** (`scenes/marketplace_ui.tscn`): Browse items for sale, filter by price in Buffalo Chips, search catalog, and instant purchase with inventory delivery.
-* **Creator Selling & Payouts** (`scenes/selling_payout_ui.tscn`): Catalog item listing, price configuration, escrow tracking (Available, In Escrow, Lifetime Earned), and cash payout requests (minimum 100 Buffalo Chips).
-
-### 6. 🌐 Discovery & Catalog
-* **World Discovery UI** (`scenes/discovery_ui.tscn`): Public world browser with search by title, tags, or category.
-* **Trending Algorithm**: Decay-weighted play counts ranking popular worlds on the discovery front page.

-## 🚀 Development, Testing & Builds
-
-### Automated Smoke Tests (Headless Godot)
-All UI panels and client subsystems have headless GDScript smoke tests:
-```bash
-# Set target backend (e.g. PC4 playtest instance)
-export AGP_API_BASE_URL=http://127.0.0.1:28004
-
-# Run individual UI & subsystem smoke tests
-~/godot/godot --headless --path . --script res://scripts/smoke_test_main_menu_full_flow.gd
-~/godot/godot --headless --path . --script res://scripts/smoke_test_marketplace_ui.gd
-~/godot/godot --headless --path . --script res://scripts/smoke_test_wallet_ui.gd
-~/godot/godot --headless --path . --script res://scripts/smoke_test_selling_payout_ui.gd
-~/godot/godot --headless --path . --script res://scripts/smoke_test_avatar_in_world.gd
-```
-
-### Backend Test Suite
-```bash
-# Run 335+ FastAPI & SQLAlchemy test suite
-PYTHONPATH=. /home/daddy/agp/venv/bin/pytest backend/tests
-```
-
-### Building Release Binaries
-```bash
-# Export Linux and Windows binaries
-scripts/build.sh
-
-# Or build pre-configured Windows package for current checkpoint (PC4):
-PYTHONPATH=. /home/daddy/agp/venv/bin/python3 -c "import pm.checkpoint_ops as ops; ops.build_exe('PC4')"
-```
-Output artifacts:
-- Windows: `export/windows/modbison.exe` (or `agp/playtest/PC4/build/windows/modbison.exe`)
-- Linux: `export/linux/modbison.x86_64`

-app/routers/chat_dm.py (DM send/list/conversations endpoints). Unread-count
-tracking is implemented as a last-read timestamp per participant: whenever a
-user fetches a conversation's message history, their
-``conversation_participants`` row's ``last_read_at`` is bumped to "now", and
-the conversation-list endpoint counts messages with
-``created_at > last_read_at`` (or all messages if never read) as unread for
-that participant. Nullable/no default so existing rows (none yet in
-practice, but consistent with "never read") read as "everything unread".
