+# xtask - Build Automation for Aspen
+
+This crate provides build automation tasks for the Aspen workspace using the [cargo-xtask pattern](https://github.com/matklad/cargo-xtask).
+
+## Usage
+
+All commands are run from the workspace root:
+
+```bash
+# Build for iOS Simulator (release mode)
+cargo xtask ios-build
+
+# Build for iOS Simulator (debug mode)
+cargo xtask ios-build --debug
+
+# Deploy to iOS Simulator
+cargo xtask ios-deploy
+
+# Deploy to a specific device
+cargo xtask ios-deploy --device "iPad Air (5th generation)"
+
+# Build, deploy, and stream logs (most common)
+cargo xtask ios-run
+
+# Build, deploy, and stream logs (debug mode)
+cargo xtask ios-run --debug
+
+# Build, deploy, and stream logs (specific device)
+cargo xtask ios-run --device "iPhone 15 Pro"
+```
+
+## Available Commands
+
+- **`ios-build`**: Builds the app for iOS Simulator (aarch64-apple-ios-sim)
+  - `--debug`: Build in debug mode (default is release)
+
+- **`ios-deploy`**: Deploys the app to iOS Simulator
+  - `--device`: Device name (default: "iPad Pro 12.9-inch M2")
+
+- **`ios-run`**: Builds, deploys, and streams logs (all-in-one)
+  - `--debug`: Build in debug mode
+  - `--device`: Device name (default: "iPad Pro 12.9-inch M2")
+
+## How It Works
+
+The xtask pattern creates a new binary target in your workspace that contains build automation code. This is better than shell scripts because:
+
+1. **Cross-platform**: Pure Rust, works everywhere Rust works
+2. **Type-safe**: Configuration and arguments are type-checked
+3. **Maintainable**: Can use the same error handling and libraries as your main code
+4. **Fast**: Compiled Rust is much faster than shell scripts
+5. **Integrated**: Can share code with your workspace
+
+## Adding New Tasks
+
+To add a new task:
+
+1. Add a new variant to the `Commands` enum in `src/main.rs`
+2. Implement the corresponding function
+3. Add the function call in the `match` statement in `main()`
+
+Example:
+
+```rust
+#[derive(Subcommand)]
+enum Commands {
+    // ... existing commands
+
+    /// Run tests on iOS Simulator
+    IosTest {
+        /// Device name
+        #[arg(long, default_value = "iPad Pro 12.9-inch M2")]
+        device: String,
+    },
+}
+
+fn ios_test(device_name: &str) -> Result<()> {
+    // Implementation here
+    Ok(())
+}
+
+fn main() -> Result<()> {
+    let cli = Cli::parse();
+    match cli.command {
+        // ... existing matches
+        Commands::IosTest { device } => ios_test(&device),
+    }
+}
+```
+
+## Dependencies
+
+- `anyhow`: Error handling
+- `clap`: Command-line argument parsing

+# Estimation and Prioritization
+
+This document defines how r3t Studios sizes, estimates, and prioritizes work. Our approach is grounded in **Lean Software Development** principles, adapted for indie game development.
+
+---
+
+## Lean Principles as Evaluation Questions
+
+Every sizing and prioritization decision should be evaluated through these questions:
+
+| Principle | Evaluation Questions |
+|-----------|---------------------|
+| **Eliminate Waste** | Does this reduce waste? Is this the simplest solution? Are we building something nobody needs? |
+| **Amplify Learning** | What will we learn from this? Does this reduce uncertainty? Should we prototype first? |
+| **Decide as Late as Possible** | Do we have enough information to commit? Can this decision be deferred responsibly? |
+| **Deliver as Fast as Possible** | What's the smallest increment that delivers value? What's blocking flow? |
+| **Empower the Team** | Do I have what I need to do this? Who else should be involved in this decision? |
+| **Build Integrity In** | Are we building quality in from the start? Will this create technical debt? |
+| **Optimize the Whole** | Does this improve the whole system or just one part? Are we sub-optimizing? |
+
+---
+
+## Sizing
+
+We use **powers of 2** for effort estimation: `1, 2, 4, 8, 16, 32`
+
+This scale is intentionally coarse. Precision in estimation is waste—we optimize for fast, good-enough decisions.
+
+| Size | Points | Description |
+|------|--------|-------------|
+| **XS** | 1 | Trivial change. A few lines, minimal risk. Less than 2 hours. |
+| **S** | 2 | Small task. Well-understood, limited scope. Half a day. |
+| **M** | 4 | Medium task. Some complexity or unknowns. About 1 day. |
+| **L** | 8 | Large task. Multiple components or significant complexity. 2-3 days. |
+| **XL** | 16 | Very large. Should probably be an epic. ~1 week. |
+| **XXL** | 32 | Epic-scale work. Multi-phase refactoring or major features. 2-4 weeks. |
+
+### Sizing Guidelines
+
+**Before assigning a size, ask:**
+
+- *Eliminate Waste*: Is this the smallest scope that delivers value?
+- *Deliver Fast*: Can we break this down further?
+- *Amplify Learning*: Is there uncertainty that inflates the estimate? Should we prototype/spike first?
+- *Optimize the Whole*: Does the estimate account for integration, testing, and platform testing (iOS + macOS)?
+
+**If the size is XL (16) or larger:**
+
+This is epic territory. Break it into phases or sub-tasks. An XL/XXL indicates the work is not well-understood or needs careful sequencing. Consider writing an RFC for XXL work.
+
+---
+
+## Priority
+
+Priority is based on **Cost of Delay**—the impact of not doing this work now.
+
+| Label | Priority | Cost of Delay Profile | Description |
+|-------|----------|----------------------|-------------|
+| **P0** | Critical | Expedite | Game-breaking bug, crash on launch, data loss, or blocks release. Drop everything. Every hour matters. |
+| **P1** | High | Fixed Date / High Value | Release blocker, community-visible bug, or deadline-driven (demo, event, content creator access). Do this sprint. |
+| **P2** | Medium | Standard | Normal feature work, engine improvements, content additions. Standard backlog work—prioritize by WSJF. |
+| **P3** | Low | Intangible | Nice-to-have, polish, research, experiments. Do when capacity allows or inspiration strikes. |
+
+### Priority Guidelines
+
+**Before assigning a priority, ask:**
+
+- *Eliminate Waste*: Should we do this at all? What happens if we never do it?
+- *Amplify Learning*: Does doing this first reduce uncertainty for other work?
+- *Decide Late*: Do we need to commit now, or can we learn more first? (Especially important for game design decisions)
+- *Optimize the Whole*: Does this unblock other high-value work? Does it improve both engine (Marathon) and game (Aspen)?
+
+---
+
+## WSJF (Weighted Shortest Job First)
+
+For backlog ordering within a priority tier, we use WSJF:
+
+```
+WSJF = Cost of Delay / Job Size
+```
+
+Where **Cost of Delay** considers:
+
+- **Player Value**: Does this improve player experience, immersion, or enjoyment?
+- **Time Criticality**: Content creator previews, demo deadlines, platform submission windows
+- **Risk Reduction**: Tech debt payoff, engine stability, enables future content/features
+
+Higher WSJF = do it first.
+
+### Example (Game Dev Context)
+
+| Item | Player Value | Time Criticality | Risk Reduction | CoD | Size | WSJF |
+|------|--------------|------------------|----------------|-----|------|------|
+| Spatial Audio | 8 | 6 | 4 | 18 | 8 | 2.25 |
+| Agent AI Polish | 6 | 2 | 2 | 10 | 16 | 0.63 |
+| Fix iOS Crash | 10 | 10 | 8 | 28 | 4 | 7.0 |
+| Low-Poly Tree Assets | 4 | 2 | 1 | 7 | 2 | 3.5 |
+
+**Order: iOS Crash (7.0), Tree Assets (3.5), Spatial Audio (2.25), AI Polish (0.63)**
+
+The crash gets fixed first (high value, small effort), then quick content wins, then larger features.
+
+---
+
+## Area Labels and Work Types
+
+Our `area/` labels map to different types of work:
+
+| Area | Typical Work | Considerations |
+|------|--------------|----------------|
+| **area/core** | Engine foundation | High risk—test thoroughly, affects everything |
+| **area/rendering** | Graphics, PBR, cameras | Test on iOS + macOS, check DPI scaling |
+| **area/audio** | Spatial audio, sound | Requires device testing, earbuds vs speakers |
+| **area/networking** | P2P, CRDT sync | Test with poor connections, edge cases |
+| **area/platform** | iOS/macOS specific | Platform-specific testing required |
+| **area/simulation** | Agent behaviors, AI | Needs playtesting, emergent behavior testing |
+| **area/content** | Art, audio assets, dialogue | Artistic review, asset pipeline testing |
+| **area/ui-ux** | Menus, HUD, accessibility | Needs user testing, various screen sizes |
+| **area/tooling** | Build, CI/CD, dev tools | Verify on fresh checkout |
+| **area/docs** | Technical specs, RFCs | Keep updated as code evolves |
+| **area/infrastructure** | Deployment, hosting | Test in staging before production |
+| **area/rfc** | Design proposals | Gather feedback before committing |
+
+---
+
+## Quick Reference
+
+### When Sizing
+
+1. Compare to recent similar work
+2. Use the Lean questions to validate scope
+3. If XL or larger, consider making it an epic with sub-tasks
+4. Bias toward smaller—deliver fast, learn, iterate
+5. Remember: estimates are for ordering work, not commitments
+
+### When Prioritizing
+
+1. Is it game-breaking (crash/data loss)? If yes, **P0**—do it now
+2. Is there a deadline (demo/release)? If yes, **P1**—this sprint
+3. Otherwise, score WSJF and order the backlog as **P2**
+4. Nice-to-haves and experiments go to **P3**
+5. Re-evaluate priorities weekly—inspiration and context change
+
+### For Solo Work
+
+- **Batching**: Group similar work (all rendering tasks, all iOS fixes) to minimize context switching
+- **Flow**: Protect deep work time—don't interrupt XL tasks with small P3 items
+- **Momentum**: Sometimes doing a quick XS/S task builds momentum for harder work
+- **Inspiration**: If you're excited about a P3 item, that's valuable—creative energy matters in game dev
