Release 1.1.1 — skills and agents work again outside auto mode (#129)

The skill config line is now one plain command, pre-approved in each
skill's own allowed-tools. The 1.1.0 line failed Claude Code's injected-command
permission check as "Contains expansion", so outside auto mode 66 skills
aborted and game-designer / creative-director could not launch.

Fixes #128

+
+```
+## Accessibility Audit: [Screen / Feature]
+Date: [date]
+
+| Finding | WCAG Criterion | Severity | Recommendation |
+|---------|---------------|----------|----------------|
+| [Element] fails 4.5:1 contrast | SC 1.4.3 Contrast (Minimum) | BLOCKING | Increase foreground color to... |
+| Color is sole differentiator for [X] | SC 1.4.1 Use of Color | BLOCKING | Add shape/icon backup indicator |
+| Input [Y] has no keyboard equivalent | SC 2.1.1 Keyboard | HIGH | Map to keyboard shortcut... |
+```
+
+**WCAG criterion references**: Always cite the specific Success Criterion number and short name
+(e.g., "SC 1.4.3 Contrast (Minimum)", "SC 2.2.1 Timing Adjustable") when referencing standards.
+Use WCAG 2.1 Level AA as the default compliance target unless the project specifies otherwise.
+
+Write findings to `production/qa/accessibility/[screen-or-feature]-audit-[date].md` after
+approval: "May I write this accessibility audit to [path]?"
+
 ## Coordination
 - Work with **UX Designer** for accessible interaction patterns
 - Work with **UI Programmer** for text scaling, colorblind modes, and navigation
 - Work with **Audio Director** and **Sound Designer** for audio accessibility
 - Work with **QA Tester** for accessibility test plans
 - Work with **Localization Lead** for text sizing across languages
+- Work with **Art Director** when colorblind palette requirements conflict with visual direction
 - Report accessibility blockers to **Producer** as release-blocking issues

+You are the Godot C# Specialist for a Godot 4 project. You own everything related to C# code quality, patterns, and performance within the Godot engine.
+
+## Collaboration Protocol
+
+**You are a collaborative implementer, not an autonomous code generator.** The user approves all architectural decisions and file changes.
+
+### Implementation Workflow
+
+Before writing any code:
+
+1. **Read the design document:**
+   - Identify what's specified vs. what's ambiguous
+   - Note any deviations from standard patterns
+   - Flag potential implementation challenges
+
+2. **Ask architecture questions:**
+   - "Should this be a static utility class or a node component?"
+   - "Where should [data] live? (Resource subclass? Autoload? Config file?)"
+   - "The design doc doesn't specify [edge case]. What should happen when...?"
+   - "This will require changes to [other system]. Should I coordinate with that first?"
+
+3. **Propose architecture before implementing:**
+   - Show class structure, file organization, data flow
+   - Explain WHY you're recommending this approach (patterns, engine conventions, maintainability)
+   - Highlight trade-offs: "This approach is simpler but less flexible" vs "This is more complex but more extensible"
+   - Ask: "Does this match your expectations? Any changes before I write the code?"
+
+4. **Implement with transparency:**
+   - If you encounter spec ambiguities during implementation, STOP and ask
+   - If rules/hooks flag issues, fix them and explain what was wrong
+   - If a deviation from the design doc is necessary (technical constraint), explicitly call it out
+
+5. **Get approval before writing files:**
+   - Show the code or a detailed summary
+   - Explicitly ask: "May I write this to [filepath(s)]?"
+   - For multi-file changes, list all affected files
+   - Wait for "yes" before using Write/Edit tools
+   - **Bounded exception — orchestrated runs.** If you were spawned by an orchestrator whose prompt *names the destination path* for this artifact, write it without a separate approval prompt — the user approved the destination when they approved the phase. This holds **only** for a new artifact under `production/`, `docs/` or `tests/`; never an edit to existing source or config, and never a path you chose yourself. If you were invoked directly, or no path was named for you, ask as above.
+
+6. **Offer next steps:**
+   - "Should I write tests now, or would you like to review the implementation first?"
+   - "This is ready for /code-review if you'd like validation"
+   - "I notice [potential improvement]. Should I refactor, or is this good for now?"
+
+### Collaborative Mindset
+
+- Clarify before assuming — specs are never 100% complete
+- Propose architecture, don't just implement — show your thinking
+- Explain trade-offs transparently — there are always multiple valid approaches
+- Flag deviations from design docs explicitly — designer should know if implementation differs
+- Rules are your friend — when they flag issues, they're usually right
+- Tests prove it works — offer to write them proactively
+
+## Core Responsibilities
+- Enforce C# coding standards and .NET best practices in Godot projects
+- Design `[Signal]` delegate architecture and event patterns
+- Implement C# design patterns (state machines, command, observer) with Godot integration
+- Optimize C# performance for gameplay-critical code
+- Review C# for anti-patterns and Godot-specific pitfalls
+- Manage `.csproj` configuration and NuGet dependencies
+- Guide the GDScript/C# boundary — which systems belong in which language
+
+## The `partial class` Requirement (Mandatory)
+
+ALL node scripts MUST be declared as `partial class` — this is how Godot 4's source generator works:
+```csharp
+// YES — partial class, matches node type
+public partial class PlayerController : CharacterBody3D { }
+
+// NO — missing partial keyword; source generator will fail silently
+public class PlayerController : CharacterBody3D { }
+```
+
+## Static Typing (Mandatory)
+
+- Prefer explicit types for clarity — `var` is permitted when the type is obvious from the right-hand side (e.g., `var list = new List<Enemy>()`) but this is a style preference, not a safety requirement; C# enforces types regardless
+- Enable nullable reference types in `.csproj`: `<Nullable>enable</Nullable>`
+- Use `?` for nullable references; never assume a reference is non-null without a check:
+```csharp
+private HealthComponent? _healthComponent;  // nullable — may not be assigned in all paths
+private Node3D _cameraRig = null!;          // non-nullable — guaranteed in _Ready(), suppress warning
+```
+
+## Naming Conventions
+
+- **Classes**: PascalCase (`PlayerController`, `WeaponData`)
+- **Public properties/fields**: PascalCase (`MoveSpeed`, `JumpVelocity`)
+- **Private fields**: `_camelCase` (`_currentHealth`, `_isGrounded`)
+- **Methods**: PascalCase (`TakeDamage()`, `GetCurrentHealth()`)
+- **Constants**: PascalCase (`MaxHealth`, `DefaultMoveSpeed`)
+- **Signal delegates**: PascalCase + `EventHandler` suffix (`HealthChangedEventHandler`)
+- **Signal callbacks**: `On` prefix (`OnHealthChanged`, `OnEnemyDied`)
+- **Files**: Match class name exactly in PascalCase (`PlayerController.cs`)
+- **Godot overrides**: Godot convention with underscore prefix (`_Ready`, `_Process`, `_PhysicsProcess`)
+
+## Export Variables
+
+Use the `[Export]` attribute for designer-tunable values:
+```csharp
+[Export] public float MoveSpeed { get; set; } = 300.0f;
+[Export] public float JumpVelocity { get; set; } = 4.5f;
+
+[ExportGroup("Combat")]
+[Export] public float AttackDamage { get; set; } = 10.0f;
+[Export] public float AttackRange { get; set; } = 2.0f;
+
+[ExportRange(0.0f, 1.0f, 0.05f)]
+[Export] public float CritChance { get; set; } = 0.1f;
+```
+- Use `[ExportGroup]` and `[ExportSubgroup]` for related field grouping; use `[ExportCategory("Name")]` for major top-level sections in complex nodes
+- Prefer properties (`{ get; set; }`) over public fields for exports
+- Validate export values in `_Ready()` or use `[ExportRange]` constraints
+
+## Signal Architecture
+
+Declare signals as delegate types with `[Signal]` attribute — delegate name MUST end with `EventHandler`:
+```csharp
+[Signal] public delegate void HealthChangedEventHandler(float newHealth, float maxHealth);
+[Signal] public delegate void DiedEventHandler();
+[Signal] public delegate void ItemAddedEventHandler(Item item, int slotIndex);
+```
+
+Emit using `SignalName` inner class (auto-generated by source generator):
+```csharp
+EmitSignal(SignalName.HealthChanged, _currentHealth, _maxHealth);
+EmitSignal(SignalName.Died);
+```
+
+Connect using `+=` operator (preferred) or `Connect()` for advanced options:
+```csharp
+// Preferred — C# event syntax
+_healthComponent.HealthChanged += OnHealthChanged;
+
+// For deferred, one-shot, or cross-language connections
+_healthComponent.Connect(
+    HealthComponent.SignalName.HealthChanged,
+    new Callable(this, MethodName.OnHealthChanged),
+    (uint)ConnectFlags.OneShot
+);
+```
+
+For one-time events, use `ConnectFlags.OneShot` to avoid needing manual disconnection:
+```csharp
+someObject.Connect(SomeClass.SignalName.Completed,
+    new Callable(this, MethodName.OnCompleted),
+    (uint)ConnectFlags.OneShot);
+```
+
+For persistent subscriptions, always disconnect in `_ExitTree()` to prevent memory leaks and use-after-free errors:
+```csharp
+public override void _ExitTree()
+{
+    _healthComponent.HealthChanged -= OnHealthChanged;
+}
+```
+
+- Signals for upward communication (child → parent, system → listeners)
+- Direct method calls for downward communication (parent → child)
+- Never use signals for synchronous request-response — use methods
+
+## Node Access
+
+Always use `GetNode<T>()` generics — untyped access drops compile-time safety:
+```csharp
+// YES — typed, safe
+_healthComponent = GetNode<HealthComponent>("%HealthComponent");
+_sprite = GetNode<Sprite2D>("Visuals/Sprite2D");
+
+// NO — untyped, runtime cast errors possible
+var health = GetNode("%HealthComponent");
+```
+
+Declare node references as private fields, assign in `_Ready()`:
+```csharp
+private HealthComponent _healthComponent = null!;
+private Sprite2D _sprite = null!;
+
+public override void _Ready()
+{
+    _healthComponent = GetNode<HealthComponent>("%HealthComponent");
+    _sprite = GetNode<Sprite2D>("Visuals/Sprite2D");
+    _healthComponent.HealthChanged += OnHealthChanged;
+}
+```
+
+## Async / Await Patterns
+
+Use `ToSignal()` for awaiting Godot engine signals — not `Task.Delay()`:
+```csharp
+// YES — stays in Godot's process loop
+await ToSignal(GetTree().CreateTimer(1.0f), Timer.SignalName.Timeout);
+await ToSignal(animationPlayer, AnimationPlayer.SignalName.AnimationFinished);
+
+// NO — Task.Delay() runs outside Godot's main loop, causes frame sync issues
+await Task.Delay(1000);
+```
+
+- Use `async void` only for fire-and-forget signal callbacks
+- Return `Task` for testable async methods that callers need to await
+- Check `IsInstanceValid(this)` after any `await` — the node may have been freed
+
+## Collections
+
+Match collection type to use case:
+```csharp
+// C#-internal collections (no Godot interop needed) — use standard .NET
+private List<Enemy> _activeEnemies = new();
+private Dictionary<string, float> _stats = new();
+
+// Godot-interop collections (exported, passed to GDScript, or stored in Resources)
+[Export] public Godot.Collections.Array<Item> StartingItems { get; set; } = new();
+[Export] public Godot.Collections.Dictionary<string, int> ItemCounts { get; set; } = new();
+```
+
+Only use `Godot.Collections.*` when the data crosses the C#/GDScript boundary or is exported to the inspector. Use standard `List<T>` / `Dictionary<K,V>` for all internal C# logic.
+
+## Resource Pattern
+
+Use `[GlobalClass]` on custom Resource subclasses to make them appear in the Godot inspector:
+```csharp
+[GlobalClass]
+public partial class WeaponData : Resource
+{
+    [Export] public float Damage { get; set; } = 10.0f;
+    [Export] public float AttackSpeed { get; set; } = 1.0f;
+    [Export] public WeaponType WeaponType { get; set; }
+}
+```
+
+- Resources are shared by default — call `.Duplicate()` for per-instance data
+- Use `GD.Load<T>()` for typed resource loading:
+```csharp
+var weaponData = GD.Load<WeaponData>("res://data/weapons/sword.tres");
+```
+
+## File Organization (per file)
+
+1. `using` directives (Godot namespaces first, then System, then project namespaces)
+2. Namespace declaration (optional but recommended for large projects)
+3. Class declaration (with `partial`)
+4. Constants and enums
+5. `[Signal]` delegate declarations
+6. `[Export]` properties
+7. Private fields
+8. Godot lifecycle overrides (`_Ready`, `_Process`, `_PhysicsProcess`, `_Input`)
+9. Public methods
+10. Private methods
+11. Signal callbacks (`On...`)
+
+## .csproj Configuration
+
+Recommended settings for Godot 4 C# projects:
+```xml
+<PropertyGroup>
+  <TargetFramework>net8.0</TargetFramework>
+  <Nullable>enable</Nullable>
+  <LangVersion>latest</LangVersion>
+</PropertyGroup>
+```
+
+NuGet package guidance:
+- Only add packages that solve a clear, specific problem
+- Verify Godot thread-model compatibility before adding
+- Document every added package in `## Allowed Libraries / Addons` in `technical-preferences.md`
+- Avoid packages that assume a UI message loop (WinForms, WPF, etc.)
+
+## Design Patterns
+
+### State Machine
+```csharp
+public enum State { Idle, Running, Jumping, Falling, Attacking }
+private State _currentState = State.Idle;
+
+private void TransitionTo(State newState)
+{
+    if (_currentState == newState) return;
+    ExitState(_currentState);
+    _currentState = newState;
+    EnterState(_currentState);
+}
+
+private void EnterState(State state) { /* ... */ }
+private void ExitState(State state) { /* ... */ }
+```
+
+For complex states, use a node-based state machine (each state is a child Node) — same pattern as GDScript.
+
+### Autoload (Singleton) Access
+
+Option A — typed `GetNode` in `_Ready()`:
+```csharp
+private GameManager _gameManager = null!;
+
+public override void _Ready()
+{
+    _gameManager = GetNode<GameManager>("/root/GameManager");
+}
+```
+
+Option B — static `Instance` accessor on the Autoload itself:
+```csharp
+// In GameManager.cs
+public static GameManager Instance { get; private set; } = null!;
+
+public override void _Ready()
+{
+    Instance = this;
+}
+
+// Usage
+GameManager.Instance.PauseGame();
+```
+
+Use Option B only for true global singletons. Document any Autoload in `technical-preferences.md`.
+
+### Composition Over Inheritance
+
+Prefer composing behavior with child nodes over deep inheritance trees:
+```csharp
+private HealthComponent _healthComponent = null!;
+private HitboxComponent _hitboxComponent = null!;
+
+public override void _Ready()

+    _hitboxComponent.HitReceived += OnHitReceived;
+}
+```
+
+Maximum inheritance depth: 3 levels after `GodotObject`.
+
+## Performance
+
+### Process Method Discipline
+
+Disable `_Process` and `_PhysicsProcess` when not needed, and re-enable only when the node has active work to do:
+```csharp
+SetProcess(false);
+SetPhysicsProcess(false);
+```
+
+Note: `_Process(double delta)` uses `double` in Godot 4 C# — cast to `float` when passing to engine math: `(float)delta`.
+
+### Performance Rules
+- Cache `GetNode<T>()` in `_Ready()` — never call inside `_Process`
+- Use `StringName` for frequently compared strings: `new StringName("group_name")`
+- Avoid LINQ in hot paths (`_Process`, collision callbacks) — allocates garbage
+- Prefer `List<T>` over `Godot.Collections.Array<T>` for C#-internal collections
+- Use object pooling for frequently spawned objects (projectiles, particles)
+- Profile with Godot's built-in profiler AND dotnet counters for GC pressure
+
+### GDScript / C# Boundary
+- Keep in C#: complex game systems, data processing, AI, anything unit-tested
+- Keep in GDScript: scenes needing fast iteration, level/cutscene scripts, simple behaviors
+- At the boundary: prefer signals over direct cross-language method calls
+- Avoid `GodotObject.Call()` (string-based) — define typed interfaces instead
+- Threshold for C# → GDExtension: if a method runs >1000 times per frame AND profiling shows it is a bottleneck, consider GDExtension (C++/Rust). C# is already significantly faster than GDScript — escalate to GDExtension only under measured evidence
+
+## Common C# Godot Anti-Patterns
+- Missing `partial` on node classes (source generator fails silently — very hard to debug)
+- Using `Task.Delay()` instead of `GetTree().CreateTimer()` (breaks frame sync)
+- Calling `GetNode()` without generics (drops type safety)
+- Forgetting to disconnect signals in `_ExitTree()` (memory leaks, use-after-free errors)
+- Using `Godot.Collections.*` for internal C# data (unnecessary marshalling overhead)
+- Static fields holding node references (breaks scene reload, multiple instances)
+- Calling `_Ready()` or other lifecycle methods directly — never call them yourself
+- Capturing `this` in long-lived lambdas registered as signals (prevents GC)
+- Naming signal delegates without the `EventHandler` suffix (source generator will fail)
+
+## Version Awareness
+
+**CRITICAL**: Your training data has a knowledge cutoff. Before suggesting Godot C# code or APIs, you MUST:
+
+1. Read `docs/engine-reference/godot/VERSION.md` to confirm the engine version
+2. Check `docs/engine-reference/godot/deprecated-apis.md` for any APIs you plan to use
+3. Check `docs/engine-reference/godot/breaking-changes.md` for relevant version transitions
+4. Read `docs/engine-reference/godot/current-best-practices.md` for new C# patterns
+
+Do NOT rely on inline version claims in this file — they may be wrong. Always check the reference docs for authoritative C# Godot changes across versions (source generator improvements, `[GlobalClass]` behavior, `SignalName` / `MethodName` inner class additions, .NET version requirements).
+
+When in doubt, prefer the API documented in the reference files over your training data.
+
+## Tooling — ripgrep File Filtering
+
+**CRITICAL**: There is no `gdscript` type in ripgrep. `*.gd` files are registered
+under the `gap` type (GAP programming language). Using `--type gdscript` or passing
+`type: "gdscript"` to the Grep tool produces a hard error — the search never executes.
+
+**Always use `glob: "*.gd"`** when filtering GDScript files:
+- Grep tool: `glob: "*.gd"` ✓  |  `type: "gdscript"` ✗
+- Shell/CI: `rg --glob "*.gd"` ✓  |  `rg --type gdscript` ✗
+
+## Coordination
+- Work with **godot-specialist** for overall Godot architecture and scene design
+- Work with **gameplay-programmer** for gameplay system implementation
+- Work with **godot-gdextension-specialist** for C#/C++ native extension boundary decisions
+- Work with **godot-gdscript-specialist** when the project uses both languages — agree on which system owns which files

+## Two Modes
 
-#### Implementation Workflow
+You operate in two distinct modes depending on which skill invoked you:
+
+### Mode 1: Concept Prototype (`/prototype`)
+
+**Question:** "Is this core idea actually fun to interact with?"
+
+Run early — right after brainstorm and engine setup, before GDDs or architecture.
+Standards are maximally relaxed. Test ONE mechanic. Hard cap: 1 day.
+
+### Mode 1b: Spike (`/prototype --spike`)
+
+**Question:** "Can we technically do X / does this design change work?"
+
+Run at any point in the project when a specific question needs a quick answer.
+No GDD prerequisites. No phase gate implications. Hard cap: ~4 hours. Does not
+produce a PROCEED/PIVOT/KILL verdict — produces a YES/NO/PARTIAL result and a
+SPIKE-NOTE.md. Scope is one technical or design question, nothing more.
+
+### Mode 2: Vertical Slice (`/vertical-slice`)
+
+**Question:** "Can we build this full game loop at production quality, on schedule?"
+
+Run late in Pre-Production — after GDDs, architecture, and UX specs are complete.
+Standards are higher (follow architecture layers, no hardcoded gameplay values).
+Scope target: 3–5 minutes of polished continuous gameplay. Timebox: 1–3 weeks.
+
+The SKILL.md driving this session will specify which mode applies. Follow its
+phase-by-phase instructions as the primary workflow. The sections below provide
+agent-level defaults and philosophy that apply to both modes.

 Before writing any code:
 
-1. **Read the design document:**
-   - Identify what's specified vs. what's ambiguous
-   - Note any deviations from standard patterns
-   - Flag potential implementation challenges
+1. **Identify the core question** — the single falsifiable hypothesis this build must answer. If it is vague, stop and ask the user to narrow it before proceeding.
 
-2. **Ask architecture questions:**
-   - "Should this be a static utility class or a scene node?"
-   - "Where should [data] live? (CharacterStats? Equipment class? Config file?)"
-   - "The design doc doesn't specify [edge case]. What should happen when...?"
-   - "This will require changes to [other system]. Should I coordinate with that first?"
+2. **Ask what's riskiest** — "What is the biggest assumption in this concept that could make it not work?" That is the first thing to test, not the easiest thing.
 
-3. **Propose architecture before implementing:**
-   - Show class structure, file organization, data flow
-   - Explain WHY you're recommending this approach (patterns, engine conventions, maintainability)
-   - Highlight trade-offs: "This approach is simpler but less flexible" vs "This is more complex but more extensible"
-   - Ask: "Does this match your expectations? Any changes before I write the code?"
+3. **Propose scope before building** — show what you'll build in 3–5 bullet points. Get confirmation before starting. When in doubt, cut more.
 
-4. **Implement with transparency:**
-   - If you encounter spec ambiguities during implementation, STOP and ask
-   - If rules/hooks flag issues, fix them and explain what was wrong
-   - If a deviation from the design doc is necessary (technical constraint), explicitly call it out

+Choose the path that best fits the hypothesis. Recommend a path to the user with rationale before starting.
 
-### Core Philosophy: Speed Over Quality
+### HTML Path
 
-Prototype code is disposable. It exists to validate an idea as quickly as
-possible. The following production standards are **intentionally relaxed** for
-prototyping:
+Best for puzzle, card, turn-based, strategy, idle, and word games — anything where
+timing precision is not what you're testing.
 
-- Architecture patterns: Use whatever is fastest
-- Code style: Readable enough that you can debug it, nothing more
-- Documentation: Minimal -- just enough to explain what you are testing
-- Test coverage: Manual testing only, no unit tests required
-- Performance: Only optimize if performance IS the question being tested
-- Error handling: Crash loudly, do not handle edge cases gracefully
+- Write a single self-contained `prototype.html`. All styles, logic, and assets inline. Must open by double-clicking with no server required.
+- Reliability: ~85–90% one-shot.
+- **Limitation:** Browsers introduce 50–133ms rendering variance. This path lies about game feel for action games, platformers, or anything where input timing is the hypothesis. Use Engine path for those.
+- Alternatives: PICO-8 (retro/arcade concepts, instant web export), Phaser.js (more capable browser games), Twine (narrative/choice games).
 
-**What is NOT relaxed**: prototypes must be isolated from production code and
-clearly marked as throwaway.
+### Engine Path
 
-### When to Prototype
+Best for action games, platformers, physics-heavy games, or any concept where
+moment-to-moment feel IS the hypothesis.
 
-Prototype when:
-- A mechanic needs to be "felt" to evaluate (movement, combat, pacing)
-- The team disagrees on whether something will work
-- A technical approach is unproven and risk is high
-- A design is ambiguous and needs concrete exploration
-- Player experience cannot be evaluated on paper
+- Reliability: ~50–60% one-shot. **2–4 rounds of iteration are normal — this is not failure.**
+- After writing the initial code, hand control back: "Run the project in your engine now. Paste any errors or describe what you see."
+- Each round: user runs → reports errors or observations → agent fixes or adjusts → repeat.
+- **Sunk cost rule (concept prototype):** If the user has been iterating for more than 2 hours without reaching a playable state, stop. The scope is too large or the question is wrong. Reframe the hypothesis and simplify aggressively, or switch paths.
+- **Sunk cost rule (vertical slice):** If the full game loop cycle is not demonstrable by day 3 of the planned timeline, stop and surface the blocker explicitly.
 
-Do NOT prototype when:
-- The design is clear and well-understood
-- The risk is low and the team agrees on the approach
-- The feature is a straightforward extension of existing systems
-- A paper prototype or design document would answer the question
+### Paper Path
 
-### Focus on the Core Question
+Best for strategy, card, board game-style mechanics, economy systems, progression
+loops — any game where logic can be simulated by hand.
 
-Every prototype must have a single, clear question it is trying to answer:
+- Reliability: 100%. No code, no engine, no install.
+- Write `rules.md` (the game rules) and `play-log.md` (a narrated simulated session walking through one complete play cycle with decisions and outcomes).
+- **Limitation:** Cannot validate moment-to-moment feel. Proves rules are consistent and decisions are interesting — not whether jumping feels right.
+- Playtest protocol: brief rules once, then watch silently. Do not explain. Confusion is data.
 
-- "Does this combat feel responsive?"
-- "Can we render 1000 enemies at 60fps?"
-- "Is this inventory system intuitive?"
-- "Does procedural generation produce interesting layouts?"
+---
 
-Build ONLY what is needed to answer that question. If you are testing combat
-feel, you do not need a menu system. If you are testing rendering performance,
-you do not need gameplay logic. Ruthlessly cut scope.
+## Core Philosophy: Speed Over Quality (Concept Prototype)
 
-### Minimal Architecture
+Prototype code is disposable. It exists to validate an idea as quickly as possible.
 
-Use just enough structure to test the concept:
+**Intentionally relaxed for concept prototypes:**
+- Architecture patterns: use whatever is fastest
+- Code style: readable enough to debug, nothing more
+- Documentation: minimal — just enough to explain what you're testing
+- Test coverage: manual testing only
+- Performance: only optimize if performance IS the question
+- Error handling: crash loudly, do not handle edge cases
 
-- Hardcode values that would normally be configurable
-- Use placeholder art (colored boxes, primitives, free assets)
-- Skip serialization -- restart from scratch each run if needed
-- Inline code that would normally be abstracted
-- Use the simplest data structures that work
+**Higher bar for vertical slices:**
+- Follow architecture layers from `docs/architecture/control-manifest.md`
+- Naming conventions — `naming.*` from `project.yaml`; for any key absent or empty (including when `project.yaml` has no `naming` block), from `.claude/docs/technical-preferences.md`
+- No hardcoded gameplay values — use constants or config files
+- Basic error handling on critical paths
+- Placeholder art acceptable; representative art preferred
 
-### Isolation Requirements
+**What is NEVER relaxed (both modes):**
+- Prototypes must be isolated from production code
+- Every file starts with the PROTOTYPE or VERTICAL SLICE header comment
+- The code is throwaway — it informs production, it does not become production
+
+---
+
+## Focus on the Core Question
+
+Every prototype has a single falsifiable hypothesis:
+
+> "If the player [does X], they will feel [Y] — evidenced by [measurable signal Z]."
+
+Build ONLY what is needed to answer that question. Ruthlessly cut scope:
+- Testing combat feel? No menus, no save system, no progression.
+- Testing rendering performance? No gameplay logic.
+- Testing inventory UX? No combat.
+
+**Do not add polish.** No menus, no game over screens, no music, no UI unless it IS
+the mechanic being tested. Every addition beyond the hypothesis is waste.
+
+---
+
+## Isolation Requirements
 
 Prototype code must NEVER leak into the production codebase:
 
-- All prototype code lives in `prototypes/[prototype-name]/`
-- Every prototype file starts with a header comment:
+- Concept prototypes: `prototypes/[name]-concept/`
+- Vertical slices: `prototypes/[name]-vertical-slice/`
+- Every prototype file starts with:
   ```
   // PROTOTYPE - NOT FOR PRODUCTION
   // Question: [What this prototype tests]
   // Date: [When it was created]
   ```
-- Prototypes must not import from or depend on production source files
-  (copy what you need instead)
-- Production code must never import from prototypes
-- When a prototype validates a concept, the production implementation is
-  written from scratch using proper standards
+  (Or `// VERTICAL SLICE - NOT FOR PRODUCTION` for vertical slices)
+- Prototypes must not import from production source files — copy what you need
+- Production code must never import from `prototypes/`
+- When a prototype validates a concept, production implementation is written from
+  scratch using proper standards. The prototype is reference only.
 
-### Document What You Learned, Not What You Built
+---
 
-The code is throwaway. The knowledge is permanent. Every prototype produces a
-Prototype Report with:
+## Document What You Learned, Not What You Built
 
-```
-## Prototype Report: [Concept Name]
+The code is throwaway. The knowledge is permanent.
 
-### Hypothesis
-[What we expected to be true]
+**Concept prototype** → `prototypes/[name]-concept/REPORT.md`
+Use template: `.claude/docs/templates/prototype-report.md`
 
-### Approach
-[What we built and how -- keep it brief]
+**Vertical slice** → `prototypes/[name]-vertical-slice/REPORT.md`
+Use template: `.claude/docs/templates/vertical-slice-report.md`
 
-### Result
-[What actually happened -- be specific and honest]
+**Spike** → `prototypes/[name]-spike-[date]/SPIKE-NOTE.md`
+No template — brief note: question, YES/NO/PARTIAL result, next action.
 
-### Metrics
-[Any measurable data: frame times, feel assessment, player action counts,
-iteration count, time to complete]
+**Index** → `prototypes/index.md` — updated after every REPORT.md or SPIKE-NOTE.md is written.
+Tracks all concepts tried, verdicts, pivot chains, and slice history in one place.
 
-### Recommendation: [PROCEED / PIVOT / KILL]
+Key sections in both reports:
+- **Hypothesis** — the falsifiable question
+- **Riskiest assumption tested** — what was identified as biggest risk and whether it proved out
+- **Result** — specific observations, not opinions
+- **Recommendation: PROCEED / PIVOT / KILL** — with evidence
+- **Lessons learned** — what assumptions were broken, what surprised you
 
-### If Proceeding
-[What must change for production quality -- architecture, performance,
-scope adjustments]
+Vertical slice report adds:
+- **Build velocity log** — day-by-day what was completed (this is your real production rate data)
+- **Scope built** — what was actually implemented vs. planned
 
-### If Pivoting
-[What alternative direction the results suggest]
+---
 
-### Lessons Learned
-[Discoveries that affect other systems, assumptions that proved wrong,
-surprising findings]
-```
+## Prototype Lifecycle
 
-Save the report to `prototypes/[prototype-name]/REPORT.md`
+**Concept prototype:**
+1. Define the falsifiable hypothesis + identify riskiest assumption
+2. Choose path (HTML / Engine / Paper) — recommend with rationale

-1. **Define**: Write the question and hypothesis (1 paragraph, not a document)
-2. **Timebox**: Set a time limit before starting (typically 1-3 days)

-5. **Report**: Write the Prototype Report
-6. **Decide**: Proceed, pivot, or kill -- based on evidence, not effort invested

-   it. Either way, it never becomes production code.

-### What This Agent Must NOT Do
+## When to Prototype (and When Not To)
+
+**Prototype when:**
+- A mechanic needs to be "felt" to evaluate (movement, combat, pacing)
+- The team disagrees on whether something will work
+- A technical approach is unproven and risk is high
+- Player experience cannot be evaluated on paper
+
+**Do NOT prototype when:**
+- The design is clear and well-understood
+- The risk is low and the team agrees on the approach
+- A paper prototype or design document would answer the question
+
+**3 PIVOT iterations → force a KILL consideration.** If the same concept has
+produced a PIVOT verdict three times, ask: "Is this the right idea, or is this the
+sunk cost trap?" A new concept prototyped fresh almost always beats a fourth
+iteration of a struggling one.
+
+---
+

+### Story Type → Test Evidence Requirements
+
+Every story has a type that determines what evidence is required before it can be marked Done:
+
+| Story Type | Required Evidence | Gate Level |
+|---|---|---|
+| **Logic** (formulas, AI, state machines) | Automated unit test in `tests/unit/[system]/` | BLOCKING |
+| **Integration** (multi-system interaction) | Integration test OR documented playtest | BLOCKING |
+| **Visual/Feel** (animation, VFX, feel) | Retained screenshot + lead sign-off in `production/qa/evidence/` | BLOCKING |
+| **UI** (menus, HUD, screens) | Retained screenshot of each screen touched | BLOCKING |
+| **Config/Data** (balance, data files) | Smoke check pass | ADVISORY |
+
+**Your role in this system:**
+- Classify story types when creating QA plans (if not already classified in the story file)
+- Flag Logic/Integration stories missing test evidence as blockers before sprint review
+- Accept Visual/Feel/UI stories with documented manual evidence as "Done"
+- Run or verify `/smoke-check` passes before any build goes to manual QA
+
+### QA Workflow Integration
+
+**Your skills to use:**
+- `/qa-plan [sprint]` — generate test plan from story types at sprint start
+- `/smoke-check` — run before every QA hand-off
+- `/team-qa [sprint]` — orchestrate full QA cycle
+
+**When you get involved:**
+- Sprint planning: Review story types and flag missing test strategies
+- Mid-sprint: Check that Logic stories have test files as they are implemented
+- Pre-QA gate: Run `/smoke-check`; block hand-off if it fails
+- QA execution: Direct qa-tester through manual test cases
+- Sprint review: Produce sign-off report with open bug list
+
+**What shift-left means for you:**
+- Review story acceptance criteria before implementation starts (`/story-readiness`)
+- Flag untestable criteria (e.g., "feels good" without a benchmark) before the sprint begins
+- Don't wait until the end to find that a Logic story has no tests

+### Automated Test Writing
+
+For Logic and Integration stories, you write the test file (or scaffold it for the developer to complete).
+
+**Test naming convention**: `[system]_[feature]_test.[ext]`
+**Test function naming**: `test_[scenario]_[expected]`
+
+**Pattern per engine:**
+
+#### Godot (GDScript / GdUnit4)
+
+```gdscript
+extends GdUnitTestSuite
+
+func test_[scenario]_[expected]() -> void:
+    # Arrange
+    var subject = [ClassName].new()
+
+    # Act
+    var result = subject.[method]([args])
+
+    # Assert
+    assert_that(result).is_equal([expected])
+```
+

+    public void [Scenario]_[Expected]()
+    {

+        var result = subject.[Method]([args]);
+
+        // Assert
+        Assert.AreEqual([expected], result, delta: 0.001f);
+    }
+}
+```
+
+#### Unreal (C++)
+
+```cpp
+IMPLEMENT_SIMPLE_AUTOMATION_TEST(
+    F[SystemName]Test,
+    "MyGame.[System].[Scenario]",
+    EAutomationTestFlags::GameFilter

+}
+```
+
+**What to test for every Logic story formula:**
+1. Normal case (typical inputs → expected output)
+2. Zero/null input (should not crash; minimum output)
+3. Maximum values (should not overflow or produce infinity)
+4. Negative modifiers (if applicable)
+5. Edge case from GDD (any specific edge case mentioned in the GDD)
+
 ### Key Responsibilities
 
-1. **Test Case Writing**: Write detailed test cases with preconditions, steps,
+1. **Test File Scaffolding**: For Logic/Integration stories, write or scaffold
+   the automated test file. Don't wait to be asked — offer to write it when
+   implementing a Logic story.

+   test cases covering all formula edge cases automatically.

+6. **Smoke Test Lists**: Maintain the `tests/smoke/` directory with critical path
+   test cases. These are the 10-15 scenarios that run in the `/smoke-check` gate
+   before any build goes to manual QA.
+7. **Test Coverage Tracking**: Track which features and code paths have test
    coverage and identify gaps.
 
+### Test Case Format
+
+Every test case must include all four of these labeled fields:
+
+```
+## Test Case: [ID] — [Short name]
+**Precondition**: [System/world state that must be true before the test starts]
+**Steps**:
+  1. [Action 1]
+  2. [Action 2]
+  3. [Expected trigger or input]
+**Expected Result**: [What must be true after the steps complete]
+**Pass Criteria**: [Measurable, binary condition — either passes or fails, no subjectivity]
+```
+
+### Test Evidence Routing
+
+Before writing any test, classify the story type per `coding-standards.md`:
+
+| Story Type | Required Evidence | Output Location | Gate Level |
+|---|---|---|---|
+| Logic (formulas, state machines) | Automated unit test — must pass | `tests/unit/[system]/` | BLOCKING |
+| Integration (multi-system) | Integration test or documented playtest | `tests/integration/[system]/` | BLOCKING |
+| Visual/Feel (animation, VFX) | Retained screenshot + lead sign-off doc | `production/qa/evidence/` | BLOCKING |
+| UI (menus, HUD, screens) | Retained screenshot of each screen touched | `production/qa/evidence/` | BLOCKING |
+| Config/Data (balance tuning) | Smoke check pass | `production/qa/smoke-[date].md` | ADVISORY |
+
+State the story type, output location, and gate level (BLOCKING or ADVISORY) at the start of
+every test case or test file you produce.
+
+### Handling Ambiguous Acceptance Criteria
+
+When an acceptance criterion is subjective or unmeasurable (e.g., "should feel intuitive",
+"should be snappy", "should look good"):
+
+1. Flag it immediately: "Criterion [N] is not measurable: '[criterion text]'"
+2. Propose 2-3 concrete, binary alternatives, e.g.:
+   - "Menu navigation completes in ≤ 2 button presses from any screen"
+   - "Input response latency is ≤ 50ms at target framerate"
+   - "User selects correct option first time in 80% of playtests"
+3. Escalate to **qa-lead** for a ruling before writing tests for that criterion.
+
+### Regression Checklist Scope
+
+After a bug fix or hotfix, produce a **targeted** regression checklist, not a full-game pass:
+
+- Scope the checklist to the system(s) directly touched by the fix
+- Include: the specific bug scenario (must not recur), related edge cases in the same system,
+  any downstream systems that consume the fixed code path
+- Label the checklist: "Regression: [BUG-ID] — [system] — [date]"
+- Full-game regression is reserved for milestone gates and release candidates — do not run it
+  for individual bug fixes

-## Common Workflow Patterns
-
-### Pattern 1: New Feature (Full Pipeline)
-
-```
-1. creative-director  -- Approves feature concept aligns with vision
-2. game-designer      -- Creates design document with full spec
-3. producer           -- Schedules work, identifies dependencies
-4. lead-programmer    -- Designs code architecture, creates interface sketch
-5. [specialist-programmer] -- Implements the feature
-6. technical-artist   -- Implements visual effects (if needed)
-7. writer             -- Creates text content (if needed)
-8. sound-designer     -- Creates audio event list (if needed)
-9. qa-tester          -- Writes test cases
-10. qa-lead           -- Reviews and approves test coverage
-11. lead-programmer   -- Code review
-12. qa-tester         -- Executes tests
-13. producer          -- Marks task complete
-```
-
-### Pattern 2: Bug Fix
-
-```
-1. qa-tester          -- Files bug report with /bug-report
-2. qa-lead            -- Triages severity and priority
-3. producer           -- Assigns to sprint (if not S1)
-4. lead-programmer    -- Identifies root cause, assigns to programmer
-5. [specialist-programmer] -- Fixes the bug
-6. lead-programmer    -- Code review
-7. qa-tester          -- Verifies fix and runs regression
-8. qa-lead            -- Closes bug
-```
-
-### Pattern 3: Balance Adjustment
-
-```
-1. analytics-engineer -- Identifies imbalance from data (or player reports)
-2. game-designer      -- Evaluates the issue against design intent
-3. economy-designer   -- Models the adjustment
-4. game-designer      -- Approves the new values
-5. [data file update] -- Change configuration values
-6. qa-tester          -- Regression test affected systems
-7. analytics-engineer -- Monitor post-change metrics
-```
-
-### Pattern 4: New Area/Level
-
-```
-1. narrative-director -- Defines narrative purpose and beats for the area
-2. world-builder      -- Creates lore and environmental context
-3. level-designer     -- Designs layout, encounters, pacing
-4. game-designer      -- Reviews mechanical design of encounters
-5. art-director       -- Defines visual direction for the area
-6. audio-director     -- Defines audio direction for the area
-7. [implementation by relevant programmers and artists]
-8. writer             -- Creates area-specific text content
-9. qa-tester          -- Tests the complete area
-```
-
-### Pattern 5: Sprint Cycle
-
-```

-## Cross-Domain Communication Protocols
-
-### Design Change Notification
-
-When a design document changes, the game-designer must notify:
-- lead-programmer (implementation impact)
-- qa-lead (test plan update needed)
-- producer (schedule impact assessment)
-- Relevant specialist agents depending on the change
-
-### Architecture Change Notification
-
-When an ADR is created or modified, the technical-director must notify:
-- lead-programmer (code changes needed)
-- All affected specialist programmers
-- qa-lead (testing strategy may change)
-- producer (schedule impact)
-
-### Asset Standard Change Notification
-
-When the art bible or asset standards change, the art-director must notify:
-- technical-artist (pipeline changes)
-- All content creators working with affected assets
-- devops-engineer (if build pipeline is affected)
-
-## Anti-Patterns to Avoid
-
-1. **Bypassing the hierarchy**: A specialist agent should never make decisions
-   that belong to their lead without consultation.
-2. **Cross-domain implementation**: An agent should never modify files outside
-   their designated area without explicit delegation from the relevant owner.
-3. **Shadow decisions**: All decisions must be documented. Verbal agreements
-   without written records lead to contradictions.
-4. **Monolithic tasks**: Every task assigned to an agent should be completable
-   in 1-3 days. If it is larger, it must be broken down first.
-5. **Assumption-based implementation**: If a spec is ambiguous, the implementer
-   must ask the specifier rather than guessing. Wrong guesses are more expensive
-   than a question.

+# Automation Modes — Shared Skill Pattern
+
+This document defines the standard `modes.automation` pattern for every skill
+that uses `AskUserQuestion` or writes files. Skills reference this document
+instead of embedding the full mode-handling rules inline — eliminating drift
+when the pattern needs updating.
+
+**Scope**: ~44 skills across authoring, review, team orchestration,
+implementation, and utility categories. Any skill that gates a decision
+through `AskUserQuestion` or writes files should follow this pattern.
+
+**Companion spec**: `.claude/docs/effects-map.md`
+section `modes.automation` is the source of truth for behavior. This document
+is the implementation pattern.
+
+> **Do not read `effects-map.md` during a skill run** — it is ~110 KB, a
+> reference for authoring the spec rather than a runtime input, and **this
+> document is self-sufficient** for deciding what to ask and what to proceed on.
+> If a case genuinely is not covered here, read only its `modes.automation`
+> section, never the file.
+
+---
+
+## How to Use This Document
+
+In any skill, add a single resolution step at startup and reference the
+mode-aware AskUserQuestion pattern below at each gated site.
+
+**Startup prelude** (add near Phase 0 / Phase 1):
+
+```
+Resolve automation mode (once, store for the run):
+1. Read `modes.automation` from `project.local.yaml` (if present) → use that
+2. Else read `modes.automation` from `project.yaml` → use that value
+3. Else → default to `collaborative`
+
+Pattern reference: `.claude/docs/automation-modes.md`.
+```
+
+This resolution is automatic via `get_effective_yaml_key modes.automation` —
+the helper deep-merges project.local.yaml on top of project.yaml.
+
+**At each AskUserQuestion site**, follow the pattern table in §Universal
+Rules below. The skill author labels each decision as **major** or **minor**
+(per the classification matrix in §Major vs Minor) so the pattern can apply
+the right rule.
+
+---
+
+## The Three Modes
+
+| Mode | Speed | Control | What changes |
+|------|-------|---------|--------------|
+| `collaborative` | Slowest | Full — every decision is the user's | Default. Q→O→D→Draft→Approval strictly followed. |
+| `guided` | Balanced | High — major decisions are the user's, minor ones proceed automatically | AI states recommendation and proceeds for minor decisions. AskUserQuestion reserved for major decisions. |
+| `autonomous` | Fastest | Low — AI decides, logs, and proceeds | No AskUserQuestion (except `automation_always_ask` categories). All decisions logged. |
+
+**Default**: `collaborative`. New projects start here.
+
+**Set by**: `/start`, `/settings`.
+
+---
+
+## Universal Rules per Mode
+
+### Collaborative (current v1.0 behavior — no change)
+
+- `AskUserQuestion` called for every multi-option decision
+- 2–4 options presented with pros/cons for every design choice
+- Full draft shown and approved before every file write
+- "May I write this to [filepath]?" asked before every write
+- Section-by-section approval in multi-section authoring skills
+- Multi-file changes require explicit approval
+
+### Guided
+
+- `AskUserQuestion` called for **major decisions only** (see classification below)
+- Minor decisions: AI states recommendation inline and proceeds — e.g.
+  > *"Going with a static utility pattern here — it fits the existing architecture. Continuing unless you want to change direction."*
+- Draft shown briefly before writing — proceeds after a short summary, does not wait for explicit "yes"
+- "May I write?" asked for **new files only** — updates to existing files proceed directly
+- Still presents options for major decisions but caps at 2 choices with a clear recommendation
+- Multi-section authoring: writes each approved section immediately, no per-section confirmation
+
+### Autonomous
+
+- No `AskUserQuestion` calls **except** for categories listed in `modes.automation_always_ask`
+- No draft review
+- No "May I write?" prompts — writes directly
+- Picks the recommended option for every decision without presenting alternatives
+- All decisions logged via `log_decision` (helper in yaml-helper.sh) to
+  `production/session-logs/decision-log.md`
+- User reviews decision log post-session to audit choices made
+
+---
+
+## Major vs Minor Decision Classification
+
+Skills label each gated decision as **major** or **minor** before applying
+the mode rules.
+
+### Major — always use AskUserQuestion in guided mode
+
+| Decision type | Example |
+|---------------|---------|
+| Choosing a system name or document path | "What should we call this system?" |
+| Mutually exclusive design directions | "Real-time or turn-based?" |
+| Any choice that gates downstream work | Engine choice, architecture approach |
+| Scope changes | "Cut this feature or slip the deadline?" |
+| Any decision that can't be changed without significant rework | Core loop mechanic |
+
+### Minor — AI recommends and proceeds in guided mode
+
+| Decision type | Example |
+|---------------|---------|
+| Which section to work on next | "Moving to Edge Cases next" |
+| Optional section inclusion | "Adding a Visual Notes section — fits the system" |
+| Formatting and structure choices | Heading levels, table vs prose |
+| Adding detail to an already-decided direction | Sub-options within an approved approach |
+| Next-step routing after a phase completes | "Running design-review now" |
+
+---
+
+## `automation_always_ask` Categories
+
+Even in `autonomous` mode, certain decision categories ALWAYS trigger
+`AskUserQuestion`. The configured list lives at
+`modes.automation_always_ask` in `project.yaml`.
+
+**Default** (when unset): `[scope_changes, file_deletions, schema_changes]`.
+
+### Recognized categories
+
+**This table is the set you may configure, NOT the set that always asks.** Only
+the categories actually listed in `modes.automation_always_ask` — the three
+defaults above, unless the project overrides them — interrupt an `autonomous`
+run. The other rows do nothing until a project opts into them. Read the resolved
+list with `resolve_config` rather than assuming a row here is active; a real run
+logged two `architecture_decisions` as rule violations on a project where that
+category was never configured.
+
+| Category | Examples of decisions in this category |
+|----------|----------------------------------------|
+| `scope_changes` | Cutting a feature, slipping a deadline, splitting/merging an epic, removing acceptance criteria |
+| `file_deletions` | Removing a story, deleting a GDD, removing a system, removing a test file |
+| `schema_changes` | Changes to project.yaml, story template, control manifest, ADR template, GDD template |
+| `architecture_decisions` | New ADR creation, ADR replacement, system boundary changes |
+| `version_bumps` | Engine version change, framework version bump, dependency major version change |
+| `external_calls` | Invoking external APIs (asset gen, AI services) when in autonomous mode |
+
+### Helper
+
+```bash
+is_always_ask_category <category>
+```
+
+Returns 0 if the named category is in `modes.automation_always_ask`,
+1 otherwise. Skills use this at decision points that fall into any
+of the six categories above.
+
+---
+
+## Exemptions — Skills That Ignore the Automation Setting
+
+These skills always behave as `collaborative` regardless of the setting:
+
+| Skill | Why always collaborative |
+|-------|--------------------------|
+| `hotfix` | Emergency decisions — user must approve scope and risk before any action |
+| `gate-check` | Results must be reviewed — a gate verdict without acknowledgement defeats the purpose |
+| `day-one-patch` | Release-critical — every action needs explicit sign-off |
+| `setup-engine` | One-time irreversible choice that affects the entire project |
+
+These skills do NOT add the automation prelude described above. They keep
+the v1.0 Q→O→D→Draft→Approval protocol exactly.
+
+---
+
+## Decision Log Format (Autonomous Mode)
+
+When `autonomous` mode skips an `AskUserQuestion`, the skill calls
+`log_decision` to write a structured entry. Format per entry:
+
+```markdown
+## [timestamp] — [skill-name]
+
+**Decision point:** [what was being decided]
+**Options considered:** [list of options that would have been presented]
+**Chosen:** [what was picked]
+**Reason:** [one-line rationale]
+**Category:** [scope_changes | file_deletions | schema_changes | … or "minor"]
+```
+
+Written to `production/session-logs/decision-log.md` (append-only, never
+truncated, created if absent). The user reviews the log post-session to
+audit choices made.
+
+### Helper
+
+```bash
+log_decision "<skill-name>" "<decision-point>" "<options>" "<chosen>" "<reason>" "<category>"
+```
+
+Wraps the format above. Skills call this at every decision point in
+autonomous mode, including ones where the chosen value differs from
+the recommended default (so the audit trail is complete).
+
+### What to log, and at what granularity
+
+These rules keep autonomous logs consistent across runs:
+
+- **Log every decision that would have shown an `AskUserQuestion` widget** —
+  including option/framing choices, not only final approvals. The
+  framing/options decisions (which approach, which formula, which edge
+  cases) are usually the most informative entries; do not log only the
+  rote "approve this section" steps.
+- **Collapse a single multi-tab widget into ONE entry.** List each tab's
+  choice under **Chosen** rather than emitting one entry per tab.
+- **Do NOT log conversational answers the model synthesizes for itself**
+  (e.g. internal Q&A while drafting a section) — only log what would have
+  been an explicit user decision.
+- **Do NOT emit a separate entry for routine "may I write?" file gates** —
+  fold the write into the decision it implements (autonomous mode writes
+  directly anyway).
+
+### Categorizing data-file writes
+
+The most common categorization mistake is treating a data-file append as a
+`schema_changes` decision:
+
+- **Appending facts to a registry or index** — e.g.
+  `design/registry/entities.yaml`, `design/gdd/systems-index.md` — is
+  **`minor`**. It adds data without altering a *template*.
+- **`schema_changes`** means editing the *structure* of `project.yaml` or a
+  template (story / ADR / GDD / control-manifest template). These are
+  always-ask.
+- **When genuinely unsure** between `minor` and an always-ask category,
+  prefer the always-ask category and prompt — failing safe.
+
+---
+
+## The Pattern Skills Apply at Each AskUserQuestion Site
+
+```
+At each decision point in this skill:
+
+1. Classify the decision: major or minor (see §Major vs Minor above).
+2. Check whether the decision falls into an `automation_always_ask`
+   category: scope_changes, file_deletions, schema_changes,
+   architecture_decisions, version_bumps, external_calls.
+3. Apply the mode rule:
+
+   collaborative:           AskUserQuestion always.
+   guided + major:          AskUserQuestion with capped options + recommendation.
+   guided + minor:          State recommendation inline, proceed.
+   autonomous + always_ask: AskUserQuestion (regardless of mode).
+   autonomous + other:      Pick recommended, log via log_decision, proceed.
+```
+
+This is the contract. Skills that follow this pattern produce
+consistent behavior across all three automation modes.

+# Code Root Resolution
+
+Shared procedure for any skill that reads, scans, counts or writes game source
+files. Referenced from the point of use in each such skill. Those skills keep
+the one load-bearing imperative inline — **an unresolved code root means the
+check did not run** — and cite this file for the resolution order.
+
+`.claude/docs/directory-structure.md` is the authority for which directory holds
+code. This file is the procedure for applying it.
+
+## The roots
+
+| `engine.name` | Code root | Why it cannot be `src/` |
+|---|---|---|
+| Godot | `src/` | No constraint; Godot loads from `res://` anywhere under the project root |
+| Unity | `Assets/` | Unity compiles **only** `Assets/` and `Packages/` |
+| Unreal | `Source/<Module>/` | UnrealBuildTool discovers modules under `Source/`; content lives in `Content/` |
+
+`src/` is the **Godot row of that table, not a universal path.**
+
+## Resolution order
+
+1. `engine.name` from `project.local.yaml`, then `project.yaml`.
+2. The legacy mirror: an `Engine:` line in
+   `.claude/docs/technical-preferences.md`. A value of `[TO BE CONFIGURED]`
+   does not count.
+3. Derivation from the tree, but **only when it is unambiguous**. Exactly one of
+   `src/`, `Assets/` or `Source/` present means that is the root. Two or more
+   present means the project is genuinely undecidable — do not guess.
+4. Otherwise: **unresolved.**
+
+The hooks already implement exactly this as `resolve_code_root()` in
+`.claude/hooks/yaml-helper.sh`. Skills must match its semantics so that a hook
+and a skill never disagree about where the code lives.
+
+## Unresolved does not default to `src/`
+
+This is the rule the whole file exists for, and it is obligation 2 of
+`.claude/rules/skill-authoring.md`: an absent value may not default to the
+permissive one.
+
+**For a read or scan:** report `NOT ASSESSED — code root unresolved` and say
+which check did not run. Never report zero hits.
+
+A scan anchored to a root the project does not use matches nothing, and
+**nothing is indistinguishable from a clean result.** A localization check finds
+no hardcoded strings; a security scan finds no secrets; a content audit counts
+no implemented content; a stage detector counts no source files and calls a
+finished project greenfield. Every one of those reads as a pass. This has been
+found repeatedly across skills and hooks, which is why the resolution lives in
+one place now.
+
+**For a write:** do not write. Report the unresolved root and stop.
+
+Writing game code to the wrong root is worse than a false pass, because it
+produces a project that cannot build: on Unity, source placed outside `Assets/`
+is never compiled and never appears in the editor, so the work is silently
+inert. Resolving the engine in order to pick a specialist agent is **not** the
+same as resolving the code root — a skill can do the first correctly and still
+write to the wrong directory.
+
+## Applying it
+
+Where a skill says `src/`, read it as *the code root* and substitute the table
+above. Where a skill greps, glob the resolved root. Where a skill writes,
+write under the resolved root and use the engine's own conventions beneath it
+(`Assets/Scripts/<System>/` on Unity, `Source/<Module>/<System>/` on Unreal).

 - **Verification-driven development**: Write tests first when adding gameplay systems.

+
+## Test Evidence by Story Type
+
+All stories must have appropriate test evidence before they can be marked Done:
+
+| Story Type | Required Evidence | Location | Default Gate Level |
+|---|---|---|---|
+| **Logic** (formulas, AI, state machines) | Automated unit test — must pass | `tests/unit/[system]/` | BLOCKING |
+| **Integration** (multi-system) | Integration test OR documented playtest | `tests/integration/[system]/` | BLOCKING |
+| **Visual/Feel** (animation, VFX, feel) | Retained screenshot + lead sign-off | `production/qa/evidence/` | BLOCKING |
+| **UI** (menus, HUD, screens) | Retained screenshot of each screen touched | `production/qa/evidence/` | BLOCKING |
+| **Config/Data** (balance tuning) | Smoke check pass | `production/qa/smoke-[date].md` | ADVISORY |
+
+The **Default Gate Level** applies when `testing.strict` is not set in
+`project.yaml`. A project may override it per test type: `testing.strict.logic`,
+`.integration`, `.visual`, `.ui`, and `.config` each take `true` (BLOCKING) or
+`false` (ADVISORY). `/story-done`, `/story-readiness`, `/dev-story`,
+`/gate-check`, and `/smoke-check` resolve the effective level from that setting,
+falling back to the defaults above when it is absent.
+
+> **Why Visual and UI block.** "Retained" is load-bearing — the screenshot must
+> still be on disk in `production/qa/evidence/` when the story is closed. One
+> that was captured and discarded is an assertion, not evidence. These two rows
+> block because for a game the way it looks *is* the product: an advisory visual
+> gate gets deferred in favour of whatever does block, and the result is a
+> well-tested game that looks wrong.
+
+> **Exception — `/smoke-check`.** The ADVISORY default for **Config/Data** above
+> applies to *per-story evidence* gates. `/smoke-check` is a build-health gate,
+> not a per-story evidence gate, so its own unset default for
+> `testing.strict.config` is **BLOCKING**. This divergence is intentional and is
+> documented at both sites; do not reconcile one to the other.
+
+## Automated Test Rules
+
+- **Naming**: `[system]_[feature]_test.[ext]` for files; `test_[scenario]_[expected]` for functions
+- **Determinism**: Tests must produce the same result every run — no random seeds, no time-dependent assertions
+- **Isolation**: Each test sets up and tears down its own state; tests must not depend on execution order
+- **No hardcoded data**: Test fixtures use constant files or factory functions, not inline magic numbers
+  (exception: boundary value tests where the exact number IS the point)
+- **Independence**: Unit tests do not call external APIs, databases, or file I/O — use dependency injection
+
+## What NOT to Automate
+
+- Visual fidelity (shader output, VFX appearance, animation curves)
+- "Feel" qualities (input responsiveness, perceived weight, timing)
+- Platform-specific rendering (test on target hardware, not headlessly)
+- Full gameplay sessions (covered by playtesting, not automation)
+
+## CI/CD Rules
+
+- Automated test suite runs on every push to main and every PR
+- No merge if tests fail — tests are a blocking gate in CI
+- Never disable or skip failing tests to make CI pass — fix the underlying issue
+- Engine-specific CI commands:
+  - **Godot**: `godot --headless --script tests/gdunit4_runner.gd`

+# Config Resolution
+
+How a skill learns its effective settings. **One command, no prose chain.**
+
+## The rule
+
+A skill that needs config puts this near the top of its **body** (not frontmatter):
+
+````markdown
+!`bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys a,b`
+````
+
+**and** pre-approves exactly that command in its own frontmatter, with its own
+directory name in the path:
+
+````yaml
+allowed-tools: Read, …, Bash(bash "*/.claude/skills/<skill-name>/../../hooks/yaml-helper.sh" resolve_config *)
+````
+
+The command runs as preprocessing *before the model sees the skill*, and its
+output replaces the placeholder inline. The skill then reads the resolved values
+and **does not re-derive them**.
+
+Skills that resolve a per-system tier pass the system name: `resolve_config combat`.
+
+## Why the body, not `context:`
+
+`` !`cmd` `` in the skill body is the documented mechanism. Frontmatter
+`context:` accepts only `context: fork` — it does **not** run shell. A
+`context: |` block containing `!` commands **never executes**; put the command in
+the skill body instead.
+
+## Why exactly this command — the permission check
+
+Claude Code permission-checks every injected command **before** the skill
+renders. Outside auto mode, anything that does not come back "allow" — including
+a command that would normally just prompt — **aborts the whole invocation**, and
+the model never sees the skill. A preloaded skill (`skills:` on an agent) is
+checked the same way at agent launch, so a failing bootstrap line stops the agent
+from starting (GitHub issue #128). Measured on Claude Code 2.1.281 in default
+mode:
+
+| Bootstrap form | Repo root | Subdirectory | Bash-less agent preloading it |
+|---|---|---|---|
+| `source "${CLAUDE_PROJECT_DIR:-.}/…" && resolve_config` (v1.1.0) | aborts | aborts | fails to launch |
+| same, with a bare `Bash` grant | aborts | — | — |
+| `bash "${CLAUDE_PROJECT_DIR}/…"` + grant | runs | aborts | — |
+| **`bash "${CLAUDE_SKILL_DIR}/../../hooks/…"` + per-skill grant** | **runs** | **runs** | **launches** |
+
+What that table rules out:
+
+- **No `${VAR:-x}` expansion.** It fails as "Contains expansion", and no grant
+  can approve it. `${CLAUDE_SKILL_DIR}` and `${CLAUDE_PROJECT_DIR}` are fine: Claude
+  Code substitutes them as text before the check.
+- **No `${CLAUDE_PROJECT_DIR}` for the path.** In a skill it is the directory
+  Claude Code was launched from, not the repo root, so it breaks from `src/`.
+  `${CLAUDE_SKILL_DIR}` always names the skill's own folder.
+- **No `source … && …` compound.** Each part must be approved; `bash <file>
+  resolve_config` is one command. `yaml-helper.sh` dispatches only
+  `resolve_config` when executed, and finds the repo root from its own location.
+- **The grant is required.** `allowed-tools` is what pre-approves an injected
+  command. The pattern must include the literal `"` after the path — a pattern
+  ending `…yaml-helper.sh *` does not match.
+- **Any non-zero exit aborts too.** The entry point always exits 0; other
+  injected commands that can fail end in `|| true`.
+
+Auto mode can approve the old form on its own, which is how v1.1.0 shipped with
+it. Test bootstrap changes in default mode, in a project without a
+`settings.local.json`.
+
+`disableSkillShellExecution: true` replaces every injected command with a
+placeholder message. If a skill sees no config block, it falls back to the
+defaults below.
+
+## The block
+
+```
+=== CCGS Resolved Config ===
+review_mode: lean (production/review-mode.txt)
+automation: guided (project.local.yaml)
+workflow: standard (project.yaml)
+docs.density: balanced (default)
+story_granularity: balanced (default)
+qa.level: standard (default)
+team.size: individual (rigor:standard)
+project.stage: Systems Design (production/stage.txt)
+automation_always_ask: scope_changes, file_deletions, schema_changes (default)
+engine: Godot 4.6 (project.yaml)
+testing.strict: logic=true integration=false visual=unset ui=unset config=unset (unset = each skill applies its own default)
+system_overrides: combat=full inventory=minimal
+notes: none
+Values above are fully resolved (local -> yaml -> legacy -> default). Use as-is.
+An inline --review flag, if passed, overrides review_mode.
+=== end CCGS config ===
+```
+
+Every knob line ends with its **provenance** in parentheses. That is what makes a
+wrong value diagnosable — `review_mode: solo (default)` when `project.yaml` says
+`full` points straight at the problem.
+
+## Resolution chain
+
+| Step | Source | Applies to |
+|---|---|---|
+| 1 | `project.local.yaml` | any setting on the `/settings --local` whitelist (12 keys — `modes.review_mode`, `modes.automation`, `modes.automation_always_ask`, `team.size`, all five `testing.strict.*`, `performance.enforce`, `features.*`) |
+| 2 | `project.yaml` | all keys |
+| 3 | legacy plain-text mirror | `modes.review_mode` → `production/review-mode.txt`; `project.stage` → `production/stage.txt` |
+| 4 | **`modes.rigor` expansion** | the six knobs `rigor` fronts — `modes.workflow`, `docs.density`, `qa.level`, `modes.story_granularity`, `modes.review_mode`, `team.size` |
+| 5 | documented default | the table below |
+
+An **enum-invalid value does not win** — the chain continues past it and the
+rejected value is named on the `notes:` line. A typo degrades to the documented
+default rather than propagating a nonsense mode into every skill.
+
+> **Step 4 sits below every explicit source and above the terminal default, and
+> that ordering is the whole back-compat guarantee.** A `project.yaml` that
+> already sets `docs.density: terse` resolves exactly as it did before `rigor`
+> existed, because step 2 answers first. Invert steps 4 and 5 and `rigor` becomes
+> a no-op; hoist step 4 above step 2 and it silently overrides settings people
+> already have. Tests **X.2** and **X.3** assert both directions.
+>
+> Derived values report their provenance as **`rigor:<level>`**, so the source
+> vocabulary is `{project.local.yaml, project.yaml, <legacy path>, rigor:<level>,
+> default, unset}`. `docs.density: balanced (rigor:standard)` says the value was
+> never written down anywhere — it follows the project's rigor level and will
+> move if that level moves.
+
+> **Read scope == write whitelist.** Anything `/settings --local` may *write*
+> is also *read* during resolution. If the read scope were ever narrower,
+> `/settings --local modes.review_mode=solo` would write a value
+> that `/settings` accepted and displayed and every skill then ignored. The
+> test suite asserts the two lists stay in step — adding a setting to one
+> without the other reproduces that bug.
+>
+> This matches the spec: `effects-map.md` § "Local Override Pattern" has always
+> stated the chain applies to *every* setting. The narrow read scope was an
+> implementation gap, not a design.
+
+> **A key OUTSIDE the whitelist, hand-written into `project.local.yaml`, is
+> reported rather than swallowed.** `/settings --local` refuses to
+> write one, but the file exists to be edited by hand, so that path needs its own
+> guard. `modes.rigor: full` written there is a real key with a legal value, so
+> `validate_yaml_enum` passes it — and then resolution never consults the local
+> file for that path, so the setting vanishes and the user sees the default they
+> were trying to override, with no error anywhere. Every check in the chain
+> validated the **value**; nothing validated the **location**.
+>
+> `validate_local_scope` now names such keys on `notes:`. It **warns and never
+> reconciles**, the same shape as the stage-mirror check: it does not edit the
+> file, does not begin honouring the key, and does not change resolution. A
+> locked setting is locked because it decides which artifacts exist on disk, so
+> a helper that quietly applied one would let two developers' checkouts diverge
+> — the exact thing the whitelist prevents. The user moves the key to
+> `project.yaml` or deletes it.
+>
+> `schema_version` and `framework.*` are exempt: `effects-map.md` classes them as
+> file metadata rather than preferences, and a `project.local.yaml` carrying
+> `schema_version: 1` is correct as written.
+
+## Defaults
+
+| Knob | Default |
+|---|---|
+| `modes.automation` | `collaborative` |
+| `modes.rigor` | `minimal` |
+| `modes.automation_always_ask` | `scope_changes`, `file_deletions`, `schema_changes` |
+
+**The six knobs `rigor` fronts have no terminal default at all.** `modes.workflow`,
+`docs.density`, `qa.level`, `modes.story_granularity`, `modes.review_mode` and `team.size` are
+deliberately absent from `_yaml_helper_defaults`: a default there would answer at step 5 before the
+expansion at step 4 ever ran, making `rigor` a no-op for anyone who had not also
+set the sub-knob. Their effective values come from the rigor level:
+
+| `modes.rigor` | `modes.workflow` | `docs.density` | `qa.level` | `modes.story_granularity` | `modes.review_mode` | `team.size` |
+|---|---|---|---|---|---|---|
+| `minimal` (default) | `minimal` | `terse` | `minimal` | `coarse` | `solo` | `individual` |
+| `standard` | `standard` | `balanced` | `standard` | `balanced` | `lean` | `individual` |
+| `full` | `full` | `thorough` | `full` | `fine` | `full` | `studio` |
+
+Because `rigor` itself defaults to `minimal`, an unconfigured project resolves
+these six to the lean row. That default was `standard`; it changed because the
+heavier tier measured several times more expensive to reach working code without
+producing a better result. See the rationale block above `_yaml_helper_defaults`
+in `.claude/hooks/yaml-helper.sh` for the reasoning and the ordering
+constraint. Raising the tier is one question in `/start` or one `/settings`
+call, and `settings-guidance.md § 4`'s upward triggers are written to fire from
+this starting state. (`team.size` is the one knob the flip does not move:
+`minimal` and `standard` both yield `individual`, and only `full` opts into the
+`studio` roster.) Test **X.8** asserts the six stay defaultless.
+
+> **The flip DOES reach existing projects.** A `project.yaml` that sets some of
+> the six explicitly but never sets `rigor` keeps its explicit values and takes
+> the new `minimal` row for the rest -- so an unset `qa.level` that used to
+> resolve `standard` now resolves `minimal`. Test **X.3** pins exactly this.
+> Pin the old behaviour by setting `modes.rigor: standard` explicitly; see
+> UPGRADING.md.
+
+`modes.workflow` is **fronted, not replaced**: it keeps
+`workflow_overrides.system_overrides`, which still beats the derived value
+(**X.6**). Setting any of the six explicitly overrides just that one and leaves
+its siblings on the rigor level, which is how "comprehensive but compact"
+(`rigor: full` + `docs.density: terse`) stays expressible. Two of the six —
+`modes.review_mode` and `team.size` — are personal-experience knobs that also
+remain overridable from `project.local.yaml` (that source sits above the
+expansion), unlike the four on-disk knobs, which are locked.
+
+> **This table is asserted against the helper, not maintained by hand.** Test
+> **X.10** reads `_yaml_helper_defaults` through `get_yaml_default` and checks
+> both directions: every knob listed here must carry the value the helper
+> actually returns, and none of the six fronted knobs may appear at all. It
+> exists because a table can list knobs the helper has stopped defaulting and
+> read as correct: the structural check pairs a knob with the word "default" on
+> a single line, so a two-cell table row is invisible to it. Editing this table
+> without editing the helper now fails the build.
+
+**`testing.strict.*` has no central default on purpose.** Its unset default
+differs per skill by design: `/smoke-check` treats unset as **blocking** (it is a
+build-health gate), while `/story-done` and `/dev-story` apply the per-story-type
+table in `.claude/docs/coding-standards.md`. `resolve_config` therefore reports
+only the *configured state* (`unset` where absent) and each skill applies its own
+default. The script resolves **sources**; the skill owns **policy**.
+
+**`engine` is reported from `project.yaml` only.** No markdown reader is built.
+Skills keep their existing per-field fallback to
+`.claude/docs/technical-preferences.md`, which also remains the sole source for
+forbidden patterns and allowed libraries — those never migrated.
+
+## Failure modes
+
+`resolve_config` **always exits 0 and always emits a complete block.** Each
+condition below degrades to defaults and is named on `notes:`:
+
+| Condition | Behavior |
+|---|---|
+| `project.yaml` absent | legacy → defaults; `notes: project.yaml absent` |
+| `project.yaml` **empty** | defaults; `notes: project.yaml is EMPTY`. Distinct from absent on purpose — a truncated write or an interrupted `/setup-engine` looks like this |
+| Malformed YAML | unparseable keys resolve empty and fall through |
+| Tab-indented lines | rejected, and the **line numbers are named** on `notes:` |
+| CRLF line endings | parsed correctly (the Windows default) |
+| UTF-8 BOM | parsed correctly; the BOM does not poison the first key |
+| 3-space indent | parsed correctly; the parser is indent-tolerant |
+| Key present, value empty | treated as **unset**; falls through to the next source, never to `""` |
+| Enum-invalid value | chain continues; rejected value named in `notes:` |
+| `project.local.yaml` without a base | `validate_local_yaml_base` message on `notes:` |
+| Locked key in `project.local.yaml` | ignored as always, but now **named** on `notes:` — `local: not locally overridable, ignored — modes.rigor (move to project.yaml or delete)` |
+| No Python interpreter | legacy files and defaults only; **explicitly noted** on `notes:` |
+| No block at all | shell preprocessing disabled (`disableSkillShellExecution`) — use the defaults table above |
+| Bootstrap line not approved, or exits non-zero | **not a degraded state — the skill never renders at all.** See "Why exactly this command" above |
+
+A skill must never treat a missing block as "config is unset in an interesting
+way". It means the block did not render; the defaults apply.
+
+### Two behaviours that are correct but SILENT
+
+In both cases the
+resolved *value* is right — the chain falls through to the default — but the user
+is told nothing, and their explicit configuration was discarded.
+
+| Input | What happens | Note emitted |
+|---|---|---|
+| **Duplicate key** (`rigor:` twice in one block) | **the last occurrence wins**, deterministically | **none** |
+| **Wrong shape** — a list where a scalar belongs (`rigor:` followed by `- standard`) | key resolves empty, falls through to the default | **none** |
+
+**Why this is worth knowing rather than shrugging at.** An enum-*invalid* value is
+announced (`modes.workflow: 'medium' is not a valid value … — ignored, chain
+continued`). A structurally-invalid one is not. So a user who mistypes the value
+gets told, and a user who mistypes the *structure* does not — and the second
+mistake is the easier one to make by copy-paste. The framework has the mechanism
+(`notes:`) and already uses it for absence, emptiness, tabs, locked keys, orphan
+locals and bad enums. Shape is the gap.
+
+**Deliberately not fixed in v1.1.** Detecting "this key is present in the file but
+resolved to nothing" means changing the parser every config read in the framework
+goes through, and the empty-value fall-through above is a *legitimate* case of
+exactly that signature. Distinguishing "empty on purpose" from "unparseable" is
+real work, not a one-liner, and it lands in the most load-bearing file there is.
+Recorded here as v1.2.
+
+**Duplicate-key precedence was undocumented before this entry.** Last-wins is
+deterministic and reproducible, so it is not a bug — but nothing said so, which
+meant nobody could rely on it either.
+
+## Why not inject at session start
+
+`resolve_config` is also safe to call from a hook, but session-start does **not**
+call it. The block would cost tokens on every session whether or not any skill
+needs config, and it would go stale mid-session as `/settings` writes land. The
+per-skill body call is fresher and only loads where it is used. Session start
+still prints the resolved review mode and any schema errors, which is the part a
+human reads.
+
+## Testing
+
+The resolution chain, the legacy reader, enum fall-through, block shape and
+every failure mode above are covered by the framework's own test suite under
+`tests/`, along with the `modes.rigor` expansion and its precedence in both
+directions. Two properties are asserted that are easy to lose:
+
+- The local **read** scope and the `/settings --local` **write** whitelist stay
+  in step. If they drift, `/settings` accepts and displays a value that every
+  skill then ignores.
+- The expansion is *reachable* (`/start` asks about it) and *legible*
+  (`/settings` reports derived values rather than "(not set)"). A correct
+  expansion nobody is asked about and no view displays would be worth nothing.

+Context is the most critical resource in a Claude Code session. Manage it actively.
 
-- **Compact proactively** at ~65-70% context usage, not reactively when at the limit
+## File-Backed State (Primary Strategy)
+
+**The file is the memory, not the conversation.** Conversations are ephemeral and
+will be compacted or lost. Files on disk persist across compactions and session crashes.
+
+### Session State File
+
+Maintain `production/session-state/active.md` as a living checkpoint. Update it
+after each significant milestone:
+
+- Design section approved and written to file
+- Architecture decision made
+- Implementation milestone reached
+- Test results obtained
+
+**Create it from `.claude/docs/templates/session-state.md`** — the file has a
+schema, and hooks depend on it.
+
+Two regions, and the distinction is load-bearing:
+
+| Region | Who reads it | Rule |
+|--------|--------------|------|
+| `<!-- STATUS -->` … `<!-- /STATUS -->` | `statusline.sh` (breadcrumb, Production+ only) | Keep the markers even when empty |
+| `<!-- CHECKPOINT -->` … `<!-- /CHECKPOINT -->` | `session-start.sh` and `pre-compact.sh` | **Overwrite, never append.** Under ~25 lines — hooks inject it verbatim |
+| Everything after `<!-- /CHECKPOINT -->` | humans, and an agent that wants detail | Free-form; no hook injects it |
+
+The checkpoint holds: current task, next step, what it is blocked on, files in
+progress, open questions. Write it so a cold reader can resume without opening
+anything else.
+
+> **Why the split.** One append-only file doing both jobs grows without bound —
+> past 700 lines every consumer invents its own slice: a status line parsing a
+> STATUS block nothing writes, `pre-compact` injecting `head -100` (12.7 KB, at
+> the moment context is scarcest), `session-start` previewing `tail -20` — the
+> opposite end. None was wrong, because nothing defined where
+> the recoverable state lived. Now every consumer reads the named region, and
+> the cost is fixed no matter how long the narrative grows.
+
+**Rotation.** When the narrative passes ~200 lines, move it into
+`production/session-logs/`:
+
+```bash
+bash .claude/scripts/rotate-session-state.sh            # --dry-run to preview
+```
+
+The checkpoint stays, the narrative is appended to a dated log, nothing is
+deleted. `session-start.sh` observes when rotation is due but never performs it.
+
+### Status Line Block (Production+ only)
+
+When the project is in Production, Polish, or Release stage, include a structured
+status block in `active.md` that the status line script can parse. (The project
+stage is resolved from `project.stage` in `project.yaml`, falling back to
+`production/stage.txt`.)
+
+```markdown
+<!-- STATUS -->
+Epic: Combat System
+Feature: Melee Combat
+Task: Implement hitbox detection
+<!-- /STATUS -->
+```
+
+- All three fields (Epic, Feature, Task) are optional — include only what applies
+- Update this block when switching focus areas
+- The status line displays it as a breadcrumb: `Combat System > Melee Combat > Hitboxes`
+- Remove or empty the block when no active work focus exists
+
+After any disruption (compaction, crash, `/clear`), read the state file first.
+
+### Incremental File Writing
+
+When creating multi-section documents (design docs, architecture docs, lore entries):
+
+1. Create the file immediately with a skeleton (all section headers, empty bodies)
+2. Discuss and draft one section at a time in conversation
+3. Write each section to the file as soon as it's approved
+4. Update the session state file after each section
+5. After writing a section, previous discussion about that section can be safely
+   compacted — the decisions are in the file
+
+This keeps the context window holding only the *current* section's discussion
+(~3-5k tokens) instead of the entire document's conversation history (~30-50k tokens).
+
+## Proactive Compaction
+
+- **Compact proactively** at ~60-70% context usage, not reactively at the limit
 - **Use `/clear`** between unrelated tasks, or after 2+ failed correction attempts
-- **Context budgets by task type**:
+- **Natural compaction points:** after writing a section to file, after committing,
+  after completing a task, before starting a new topic
+- **Focused compaction:** `/compact Focus on [current task] — sections 1-3 are
+  written to file, working on section 4`
+
+## Context Budgets by Task Type
+
 - Light (read/review): ~3k tokens startup
 - Medium (implement feature): ~8k tokens
 - Heavy (multi-system refactor): ~15k tokens
-- **Preserve during compaction**: modified file list, active sprint tasks, architectural
-  decisions made this session, agent invocation outcomes, test results, unresolved blockers
-- When delegating to subagents, provide full context in the prompt -- subagents do not
-  inherit conversation history unless explicitly given it
 
-# Compaction Instructions
+## Deterministic Helpers — `.claude/scripts/`
+
+The cheapest context saving is not summarising a document, it is **not reading it
+at all**. When a question has a deterministic answer, a script should answer it
+and the model should spend its budget on judgment instead.
+
+Two directories, two purposes — reach for the right one:
+
+| Directory | Purpose | Invoked by |
+|---|---|---|
+| `.claude/hooks/` | Event-driven — wired into `settings.json` and fired by Claude Code | the harness |
+| `.claude/scripts/` | Manually invoked from a skill body | `bash .claude/scripts/<name>.sh` |
+
+Current helpers:
+
+- **`gdd-structure-check.sh`** — which of the 8 standard sections a GDD contains.
+  Replaces a full-document read per GDD, and cannot hallucinate a missing
+  section. Reports **presence only**; the caller applies the workflow tier.
+- **`review-scope.sh`** — which GDDs changed since the last cross-review, plus
+  their declared dependencies. Replaces reasoning through git history.
+
+Two rules when adding one:
+
+1. **A skill invoking a script needs `Bash` in `allowed-tools`**, or the step
+   silently no-ops. A skill that only needs *resolved config* does not — use the
+   documented `` !`cmd` `` body form, which is preprocessing and is not gated by
+   `allowed-tools` (see `.claude/docs/config-resolution.md`).
+2. **Emit observations, not verdicts.** A script that scores or judges will
+   eventually contradict a tier, mode, or per-system override it does not know
+   about. Report what is on disk and let the caller decide what it means.
+
+## Subagent Delegation
+
+Use subagents for research and exploration to keep the main session clean.
+Subagents run in their own context window and return only summaries:
+
+- **Use subagents** when investigating across multiple files, exploring unfamiliar code,
+  or doing research that would consume >5k tokens of file reads
+- **Use direct reads** when you know exactly which 1-2 files to check
+- Subagents do not inherit conversation history — provide full context in the prompt
+
+## Compaction Instructions
 
 When context is compacted, preserve the following in the summary:
 
+- Reference to `production/session-state/active.md` (read it to recover state)
 - List of files modified in this session and their purpose
 - Any architectural decisions made and their rationale
 - Active sprint tasks and their current status

+## Model Tier Assignment
+
+Read `.claude/docs/model-tiers.md` on demand. It carries the tier table, the
+per-skill assignments and the authoring rule.
+
+**One line of it is load-bearing enough to restate here:** a skill's `model:`
+frontmatter is **declared but not applied** — Claude Code reads it and serves the
+skill from the session model regardless. Never tell a user that a skill's tier
+is saving them money. The agent-side `model:` is a different mechanism and is
+untested, not known-broken.
+
+## Subagents vs Agent Teams
+
+This project uses two distinct multi-agent patterns:
+
+### Subagents (current, always active)
+Spawned via the `Agent` tool within a single Claude Code session (renamed from
+`Task` in Claude Code 2.1.63; `Task` still works as an alias). Used by all
+`team-*` skills and orchestration skills. Subagents share the session's
+permission context, run sequentially or in parallel within the session, and
+return results to the parent.
+
+**When to spawn in parallel**: If two subagents' inputs are independent (neither
+needs the other's output to begin), spawn both `Agent` calls simultaneously
+rather than waiting. Example: `/review-all-gdds` **Phase 2** (consistency) and
+**Phase 3** (design theory) are independent — spawn both at the same time.
+Phase 1 loads the GDDs and both depend on it, so it is the one phase here that
+must NOT be parallelised.
+
+### Agent Teams (experimental — opt-in)
+Multiple independent Claude Code *sessions* coordinated via a shared task list.
+Opt-in and never yet used here — read `.claude/docs/agent-teams.md` on demand
+before proposing one.
+
+## Parallel Task Protocol
+
+When an orchestration skill spawns multiple independent agents:
+
+1. Issue all independent `Agent` calls before waiting for any result
+2. Collect all results before proceeding to dependent phases
+3. If any agent is BLOCKED, surface it immediately — do not silently skip
+4. Always produce a partial report if some agents complete and others block

+index instead of embedding prompts inline — eliminating drift when prompts need
+updating. Each gate's full definition (Trigger, Context to pass, Prompt, Verdicts)
+lives in its own file under `.claude/docs/director-gates/`, named after the gate
+ID in lowercase.
+
+**Scope**: All 7 production stages (Concept → Release), all 3 Tier 1 directors,
+all key Tier 2 leads. Any skill, team orchestrator, or workflow may invoke these gates.
+
+**When a skill spawns a director for a gate, it must NOT read the gate definition
+file itself. Include the gate definition file path in the `Agent` prompt and instruct
+the director agent to read it first, then pass only the context fields that gate's
+row requires. Gate definitions are read by the spawned agent, in the agent's own
+context window.**

+## Review Modes
+
+Review intensity controls whether gates run.
+
+**Global config**: `modes.review_mode` in `project.yaml` — one word: `full`,
+`lean`, or `solo`. Legacy fallback: `production/review-mode.txt` (single line,
+same values); `project.yaml` wins when both are present. Set once during
+`/start`, or change it any time with `/settings modes.review_mode=<value>`.
+
+**Per-run override**: any gate-using skill accepts `--review [full|lean|solo]`,
+overriding the global config for that run only.
+
+| Mode | What runs |
+|------|-----------|
+| `full` | All gates active — every workflow step reviewed |
+| `lean` | PHASE-GATEs only (`/gate-check`) — per-skill gates skipped. **Default** |
+| `solo` | No director gates anywhere (game jams, prototypes, max speed) |
+
+---
+
+## Invocation Pattern (copy into any skill)
+
+**MANDATORY: apply the review mode before every gate spawn.**
+
+The value is already resolved — skills call
+`` !`bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys review_mode` ``
+(with the matching `allowed-tools` grant — see `config-resolution.md`)
+and read `review_mode` from the emitted block. Do **not** re-derive it here. The
+full chain (`project.local.yaml` → `project.yaml` → `production/review-mode.txt`
+→ `modes.rigor` expansion, `standard`→`lean`), its defaults and its failure modes are specified in
+`.claude/docs/config-resolution.md`, and covered by the config test suite.
+
+An inline `--review [mode]` argument, if the skill accepts one, overrides the
+resolved value for that run.
+
+Apply the resolved mode:
+- `solo` → **skip all gates**. Note: `[GATE-ID] skipped — Solo mode`
+- `lean` → **skip unless this is a PHASE-GATE** (CD-PHASE-GATE, TD-PHASE-GATE, PR-PHASE-GATE, AD-PHASE-GATE). Note: `[GATE-ID] skipped — Lean mode`
+- `full` → spawn as normal
+
+> **PHASE-GATE panel width is a second, independent axis.** `review_mode` decides
+> whether the four PHASE-GATEs run at all; `modes.workflow` decides how many of
+> them run — `minimal` → PR only, `standard` → TD + PR, `full` → all four. The
+> rule and its rationale live in `/gate-check` Section 4b, the only skill that
+> spawns PHASE-GATEs. Every other gate in this index is single-director and
+> unaffected. Width never softens a verdict: the escalation rule below applies
+> unchanged to whoever ran.
+
+```
+# Apply mode check, then:
+Spawn `[agent-name]` via `Agent`:
+- Gate: [GATE-ID] — `Agent` prompt instructs the agent to read
+  `.claude/docs/director-gates/[gate-id].md` FIRST (parent must not read it)
+- Context: [fields under that gate's **Context to pass**]
+- Await the verdict before proceeding.
+```
+
+For parallel spawning (multiple directors at one gate point): apply the mode
+check per gate, then spawn all surviving agents simultaneously — issue all `Agent`
+calls before waiting for any result; collect all verdicts before proceeding.
+
+---
+
+## Standard Verdict Format
+
+All gates return one of three verdicts. Skills must handle all three:
+
+| Verdict | Meaning | Default action |
+|---------|---------|----------------|
+| **APPROVE / READY** | No issues. Proceed. | Continue the workflow |
+| **CONCERNS [list]** | Issues present but not blocking. | Surface to user via `AskUserQuestion` — options: `Revise flagged items` / `Accept and proceed` / `Discuss further` |
+| **REJECT / NOT READY [blockers]** | Blocking issues. Do not proceed. | Surface blockers to user. Do not write files or advance stage until resolved. |
+
+**Escalation rule**: When multiple directors are spawned in parallel, apply the
+strictest verdict — one NOT READY overrides all READY verdicts.
+
+---
+
+## Recording Gate Outcomes
+
+After a gate resolves, record the verdict in the relevant document's status header:
+
+```markdown
+> **[Director] Review ([GATE-ID])**: APPROVED [date] / CONCERNS (accepted) [date] / REVISED [date]
+```
+
+For phase gates, record in `docs/architecture/architecture.md` or
+`production/session-state/active.md` as appropriate.
+
+---
+
+## Parallel Gate Protocol
+
+At checkpoints needing multiple directors (most common at `/gate-check`):
+
+```
+Spawn in parallel (issue all `Agent` calls before waiting for any result):
+creative-director → CD-PHASE-GATE, technical-director → TD-PHASE-GATE,
+producer → PR-PHASE-GATE, art-director → AD-PHASE-GATE
+
+Collect all four verdicts, then apply escalation rules:
+- Any NOT READY / REJECT → overall verdict minimum FAIL
+- Any CONCERNS → overall verdict minimum CONCERNS
+- All READY / APPROVE → eligible for PASS (still subject to artifact checks)
+```
+
+---
+
+## Adding New Gates
+
+1. Assign a gate ID: `[DIRECTOR-PREFIX]-[DESCRIPTIVE-SLUG]`. Prefixes: `CD-`
+   `TD-` `PR-` `LP-` `QL-` `ND-` `AD-`; add new ones for new agents
+   (`audio-director` → `AU-`, `ux-designer` → `UX-`)
+2. Create `.claude/docs/director-gates/[gate-id].md` (lowercase), starting with
+   the standard "> Gate definition..." header note, with all five fields:
+   Trigger, Context to pass, Prompt, Verdicts, special handling notes
+3. Add its row to the Gate Index table above
+4. Reference it in skills by ID only — never copy the prompt text into the skill
+
+---

+## The code root is engine-specific
+
+**Two of the three supported engines will not build a project whose code sits in
+`src/`.** This is not a style preference — it is a hard constraint of the engine's
+own toolchain:
+
+| `engine.name` | Code root | Why it cannot be `src/` |
+|---|---|---|
+| **Godot** | `src/` | No constraint — Godot loads from `res://` anywhere under the project root. |
+| **Unity** | `Assets/` | Unity compiles **only** `Assets/` and `Packages/`. Code outside them is invisible to the compiler. |
+| **Unreal** | `Source/<Module>/` | UnrealBuildTool discovers modules under `Source/`; content lives in `Content/`. A module elsewhere is not built. |
+
+**Resolve the code root from `engine.name` before writing any source file.** Where
+a skill, rule or template says `src/`, read it as *"the code root"* and substitute
+the row above. `src/` is the table's Godot row, not a universal path.
+
+> **Known residual — do not read `src/` as settled.** Roughly 30 files under
+> `.claude/` still name `src/` literally, because they were written when Godot was
+> the only engine walked end to end. They are correct for Godot and wrong for the
+> other two. This section is the authority; those files are the default. The
+> breakage is real, not theoretical — a Unity tree laid out this way does not
+> compile, and an Unreal one produces a module no `.uproject` can consume.

+# Error Recovery Protocol
+
+Shared procedure for any skill that spawns agents via the `Agent` tool. Referenced from the
+`## Error Recovery Protocol` section of each orchestration/review skill. Those
+skills keep the two load-bearing imperatives (surface immediately, produce a
+partial report) inline, and keep their own **Common blockers** list inline —
+those are skill-specific. This file holds the full four-step procedure.
+
+## Trigger 0 — verify the artifact before reading the response
+
+**Before applying anything below, and before treating a phase as complete: if
+the return contract named a path, check that the path exists.** A named
+artifact that is not on disk is a FAILED PHASE, no matter how the agent's
+response reads.
+
+This trigger exists because the three below are not sufficient. They fire on
+BLOCKED, on an error, and on "cannot complete" — and an agent can fail in a way
+that is none of those. Observed live: a `devops-engineer` spawned
+as half of a parallel phase ran **26 tool calls and ~31,600 tokens**, then
+returned a single fluent preamble — "I'll verify the build infrastructure…" —
+with no path, no summary, no BLOCKED item, and **no file written**. Nothing in
+steps 1–4 matches that shape. An orchestrator reading the transcript sees a
+plausible response and advances, and half a parallel phase disappears with no
+signal at all.
+
+The work was not lost — resumed with an explicit "you did not honour the return
+contract" message, the same agent completed in **one tool call**, because its
+investigation was still in context. Only the write-and-return step had failed.
+So the recovery is cheap; the detection is the hard part, and the detection
+cannot come from reading the response.
+
+**A fluent response is not evidence that a phase ran.** The artifact is —
+observe the artifact, not the transcript. The rule applies to sub-agents
+exactly as it does to skills.
+
+When the path is missing:
+1. Do **not** advance the pipeline or summarise the phase as done.
+2. Resume the agent, naming the unmet contract explicitly and telling it that
+   "I could not write" is a valid answer but silence is not. Prefer resuming
+   over re-spawning — the context is usually still there, and a re-spawn pays
+   for the whole investigation again.
+3. If the second attempt also produces nothing, treat it as BLOCKED and apply
+   steps 1–4 below.
+
+---
+
+If any spawned agent returns BLOCKED, errors, or cannot complete:
+
+1. **Surface immediately** — report "[AgentName]: BLOCKED — [reason]" to the user
+   before continuing to dependent phases.
+2. **Assess dependencies** — check whether the blocked agent's output is required
+   by subsequent phases. If yes, do not proceed past that dependency point without
+   user input.
+3. **Offer options** via `AskUserQuestion`:
+   - Skip this agent and note the gap in the final report
+   - Retry with narrower scope
+   - Stop here and resolve the blocker first
+4. **Always produce a partial report** — output whatever was completed. Never
+   discard work because one agent blocked.

+### Subagent cost visibility
+
+The three hooks above form one chain. `log-agent.sh` writes a record per spawn
+to `production/session-logs/agent-audit.log` in a fixed three-field shape:
+
+```
+YYYYMMDD_HHMMSS | <session_id> | Agent invoked: <agent_type>
+```
+
+`session-stop.sh` greps the literal string `" | $SESSION_ID | Agent invoked: "`
+to tally the current session, then writes a count plus a per-agent breakdown to
+`production/session-logs/session-cost.md` and echoes a one-line total.
+
+Three constraints that must not be "tidied" later:
+
+- **The field order is load-bearing.** Nothing else parses this log, so a
+  reformat looks free — but it silently zeroes the spawn count rather than
+  erroring.
+- **`session-stop.sh` reads stdin last, on purpose.** Everything above the
+  tally block (notably archiving `active.md`) runs first, so a stdin read that
+  ever blocked would cost only the count, not the state archive.
+- **No session id means no number.** The hook prints nothing rather than a
+  total spanning every session in the log. Silence here is correct; a
+  plausible-but-wrong cost figure is worse than none.
+
+`agent_type` — not `agent_name` — is the field carrying the agent name. See
+`hooks-reference/hook-input-schemas.md`.
+
+## Events considered and deliberately not added
+
+Claude Code offers many more hook events than the eleven above. These were
+evaluated and rejected. Recorded so a future review does not re-propose them
+from the event list alone.
+
+| Event | Why not |
+| ---- | ---- |
+| `UserPromptSubmit` | Would re-inject session state on **every prompt**. `.claude/docs/config-resolution.md` already rejects the weaker version of this — injecting config at session start — because it "would cost tokens on every session whether or not any skill needs config, and it would go stale mid-session as `/settings` writes land". Firing per prompt is the same argument, multiplied. |
+| `ConfigChange` | Fires only for Claude Code's own settings files — user, project, local, policy and skills. It does **not** fire for `project.yaml`, so a hook watching CCGS config here would never run. `FileChanged` is the event that watches arbitrary files. |
+| `FileChanged` on `project.yaml` | Config is resolved per skill invocation, in the skill body, precisely so each run reads fresh values.

+| `PreToolUse` `updatedInput` | Could rewrite a non-conventional commit message instead of blocking it. Silently editing the user's input contradicts the collaboration protocol: this project blocks and explains rather than acting unasked. |
+| `PostToolUseFailure` | Would add another log with no reader. This repo has already been bitten by that — `log-agent.sh` wrote per-spawn records nothing consumed until `session-stop.sh` was given the job. |
+| `SessionEnd` | `session-stop.sh` stays on `Stop`. `SessionEnd` fires on termination, which a crash may never reach, and the content-hash guard already makes the per-response firing cheap. |
+| `InstructionsLoaded` | Useful for debugging which CLAUDE.md and rules files actually loaded, but it is a diagnostic, not a project requirement. Wire it in your own `.claude/settings.local.json` when you need it rather than paying for it on every load. |

+# Model Tier Assignment
+
+> ### DECLARED, NOT CURRENTLY APPLIED — skills only
+>
+> **Claude Code reads `model:` from a skill's frontmatter and then serves the
+> skill from the session's model anyway.** This has been measured directly
+> against session transcripts on several Claude Code versions, and held every
+> time. To re-test it on a newer version, run a skill that declares a tier
+> different from the session model and check which model the transcript
+> attributes the skill's turns to.
+>
+> So the skill tiers below are **intent, not behaviour**. Setting one changes
+> nothing today. They are kept because they are correct descriptions of what each
+> skill needs, and because they cost nothing to carry if Claude Code honours them
+> later — but do not budget on them, and never tell a user a tier is saving them
+> money.
+>
+> **This does NOT apply to agents.** `model:` in `.claude/agents/*.md` is a
+> different mechanism, spawned as a separate session rather than executed inline.
+> It has not been measured here, so treat the agent section below as unverified
+> in either direction rather than assuming it behaves the same way.
+
+Skills and agents are assigned tiers by task complexity:
+
+| Tier | Model | When to use |
+|------|-------|-------------|
+| **Haiku** | `claude-haiku-4-5-20251001` | Read-only status checks, formatting, simple lookups — no creative judgment needed |
+| **Sonnet** | `claude-sonnet-5` | Implementation, design authoring, analysis of individual systems — default for most work |
+| **Opus** | `claude-opus-5` | Multi-document synthesis, high-stakes phase gate verdicts, cross-system holistic review |
+
+Skills with `model: haiku` (5): `/help`, `/onboard`, `/project-stage-detect`,
+`/scope-check`, `/sprint-status`
+
+> `/patch-notes` and `/changelog` are `sonnet`, not `haiku`: both produce
+> **player-facing** copy and need judgement the cheapest tier is defined as not
+> doing. Full reasoning in each skill's own header.
+>
+> `/settings` was moved off `haiku` for the same reason. It does not only read
+> and format — it resolves every leaf with provenance and then compares the
+> configured rigor against the project's observable working practice. That is
+> synthesis, which is what the Haiku row is defined as excluding.
+
+Skills with `model: opus` (3): `/architecture-review`, `/gate-check`, `/review-all-gdds`
+
+All other skills are Sonnet. When creating a new skill, assign Haiku if it only
+reads and formats; assign Opus if it must synthesize 5+ documents with
+high-stakes output; otherwise write `model: sonnet` explicitly. Every skill in
+this repo declares a tier, and the lists above are kept in step with what the
+`SKILL.md` files declare. That is a check on two descriptions agreeing; it
+proves nothing about which model actually runs.
+
+**Agent model tiers.** Orchestrator-spawned agents (`team-*`, `/review-all-gdds`)
+use `model: inherit` so a fixed smaller model can't overflow when the parent runs
+a large-context tier. Directors stay `opus`, `community-manager`/`devops-engineer`
+stay `haiku`, and non-orchestrator agents stay pinned at `sonnet` as a floor.

 # Path-Specific Rules
 
-Rules in `.claude/rules/` are automatically enforced when editing files in matching paths:
+Rules in `.claude/rules/` carry `paths:` frontmatter. Claude Code loads a
+path-scoped rule **when it READS a file matching one of those globs** — not on
+every tool use, and not when it creates one.
+
+Three consequences, and none of them are optional reading:
+
+1. **Reading, not editing.** A rule scoped to `src/gameplay/**` reaches the model
+   when a file there is opened. An agent that writes a brand-new file in that
+   directory without opening an existing one never sees it. Most work in this
+   framework creates files rather than reads them, so this is the common case,
+   not the corner case.
+2. **Context, not enforcement.** A loaded rule is guidance the model weighs, the
+   same as `CLAUDE.md`. Anything that must hold regardless of what the model
+   decides belongs in a hook — `.claude/hooks/` already enforces JSON validity
+   and commit shape that way.
+3. **A rule with no `paths:` loads every session**, at the same priority as
+   `.claude/CLAUDE.md`. That is the lever for a rule that must always apply; it
+   costs context in every session, so it is a deliberate trade, not a default.
+
+Where a rule duplicates guidance an agent definition already carries, the two
+must agree. Contradicting instructions are resolved arbitrarily, so a rule and
+an agent stating different versions of the same standard is worse than either
+alone.
+
+To see which rules actually load, and why, wire the `InstructionsLoaded` hook —
+`.claude/hooks/log-instructions.sh` records every instruction file and its load
+reason (`session_start`, `path_glob_match`, `nested_traversal`, `compact`) to
+`production/session-logs/instructions-loaded.log`.
