-# Project Philosophy
-
-This project prioritizes **clarity, correctness, and maintainability** over defensive boilerplate or unnecessary abstraction.
-
-AI-generated code should:
-
-* follow existing architecture
-* keep logic simple and explicit
-* avoid hiding bugs
-* avoid speculative abstractions
-
-If uncertain, prefer **simple direct code** over generalized frameworks.
-
-## Repository Guidelines
-
-### Project Structure & Module Organization
-- `Assets/` contains all Unity assets and code. Game-specific content lives under `Assets/GameMain/`.
-- `Assets/GameMain/Scripts/` holds gameplay code organized by domain (`Procedure/`, `Entity/`, `UI/`, `Scene/`, `Sound/`, `Utility/`).
-- `Assets/GameMain/Scenes/` stores Unity scenes (start from `Assets/Launcher.unity`).
-- `Assets/GameMain/Configs/` and `Assets/GameMain/DataTables/` store runtime configuration and data tables.
-- `StreamingAssets/` is for runtime-loaded files that must be preserved on build.
-- `docs/` contains design notes (see `docs/GameDesign.md`).
-- `数据表/` is a top-level data table workspace; keep it in sync with `Assets/GameMain/DataTables/` when exporting.
-
-### Build, Test, and Development Commands
-- Open the project with Unity Hub and load `GeometryTD` as a Unity project.
-- Play locally via the Unity Editor Play button (no custom CLI runner is defined in this repo).
-- Build via Unity: `File > Build Settings...` then choose target and build.
-- IDE support: open `GeometryTD.sln` or `Assembly-CSharp.csproj` for C# navigation and tooling.
-
-### Coding Style & Naming Conventions
-- C# uses 4-space indentation and Allman braces (see `Assets/GameMain/Scripts/Procedure/ProcedureLaunch.cs`).
-- Types, methods, and public members use `PascalCase`; locals and parameters use `camelCase`.
-- Namespaces follow `GeometryTD.*` by feature area (example: `GeometryTD.Procedure`).
-- Keep Unity `.meta` files with their assets; do not delete or regenerate them manually.

-## Code Design Principles
-
-### 1. Prefer explicit logic over abstraction
-
-Do not introduce abstractions unless they are clearly justified.
-
-Avoid creating layers such as:
-
-```
-Manager
-Service
-Provider
-Repository
-Coordinator
-Bridge
-```
-
-unless the architecture explicitly requires them.
-
-Simple gameplay logic should remain simple.
-
-Bad example:
-
-```
-EnemyService -> EnemyManager -> EnemyRepository
-```
-
-Good example:
-
-```
-EnemySpawner
-Enemy
-EnemyAI
-```
-
----
-
-### 2. Do not create abstractions for a single implementation
-
-Avoid introducing interfaces unless multiple implementations are expected.
-
-Bad:
-
-```
-IEnemyService
-EnemyService
-```
-
-Good:
-
-```
-EnemySystem
-```
-
-Interfaces are only appropriate when:
-
-* multiple implementations are required
-* plugin/mod systems are involved
-* testing requires mocking
-* architecture explicitly defines extension points
-
----
-
-### 3. Avoid speculative generalization
-
-Do not design systems for hypothetical future use.
-
-Implement only what the current feature requires.
-
-Avoid:
-
-* generic service layers
-* premature plugin systems
-* unnecessary configuration frameworks
-
----
-
-## Defensive Programming Policy
-
-### Boundary validation only
-
-Validation is appropriate only at **true system boundaries**, such as:
-
-* user input
-* network input
-* file/config loading
-* inspector/external data
-* public API boundaries
-
-Internal gameplay logic should assume that invariants are already satisfied.
-
-Do not add redundant validation inside internal code.
-
----
-
-### Do not hide errors
-
-Do not silently ignore invalid states.
-
-Avoid code such as:
-
-```
-if (enemy == null)
-    return;
-```
-
-or
-
-```
-if (config == null)
-    continue;
-```
-
-unless the behavior is intentionally designed.
-
-Unexpected states should be **visible**, not hidden.
-
----
-
-### Prefer fail-fast over silent failure
-
-If a condition should never happen in correct execution:
-
-Use assertions.
-
-Example:
-
-```
-Debug.Assert(config != null);
-```
-
-Do not convert invariant violations into no-op behavior.
-
-Bad:
-
-```
-if (config == null)
-    return;
-```
-
-Good:
-
-```
-Debug.Assert(config != null);
-```
-
----
-
-### Do not weaken required dependencies
-
-Required references must remain required.
-
-Do not turn required dependencies into optional ones by adding defensive checks.
-
-Bad:
-
-```
-if (enemy.Config == null)
-    return;
-```
-
-If a dependency is required by design, assume it exists.
-
----
-
-## Error Handling
-
-Do not introduce `try/catch` blocks unless there is a **clear recovery strategy**.
-
-Avoid:
-
-```
-try
-{
-    DoSomething();
-}
-catch (Exception e)
-{
-    Debug.LogError(e);
-}
-```
-
-Exceptions should generally propagate during development so bugs are visible.
-
----
-
-## Early Return Policy
-
-Early returns are acceptable for **normal control flow simplification**.
-
-However, do not use early returns to hide invariant violations or missing required state.
-
-Bad:
-
-```
-if (enemy == null)
-    return;
-```
-
-Good:
-
-```
-if (!enemy.IsAlive)
-    return;
-```
-
----
-
-## Logging
-
-Avoid excessive logging.
-
-Do not log inside per-frame loops unless necessary.
-
-Avoid logs like:
-
-```
-Debug.Log("Updating enemy");
-```
-
-Use logging only when it provides meaningful debugging value.
-
----
-
-## Utility Classes
-
-Avoid creating generic utility classes such as:
-
-```
-GameUtils
-CommonHelper
-MathHelper
-```
-
-Prefer placing behavior in the domain object responsible for it.
-
-Example:
-
-Bad:
-
-```
-DamageHelper.CalculateDamage(...)
-```
-
-Good:
-
-```
-enemy.CalculateDamage(...)
-```
-
----
-
-## Data Structures
-
-Avoid large context objects with many loosely related fields.
-
-Bad:
-
-```
-EffectContext
-{
-    int value;
-    int count;
-    float rate;
-    object source;
-    object target;
-}
-```
-
-Prefer explicit parameters or strongly typed structures.
-
----
-
-## Code Generation Rules for AI
-
-Before adding any of the following:
-
-* null check
-* range check
-* fallback default
-* try/catch
-* abstraction layer
-
-First determine:
-
-1. Is this a boundary input?
-2. Is the value optional by design?
-3. Is there a real recovery strategy?
-
-If the answer is **no**, do not add defensive code.
-
----
-
-## Preferred Coding Style
-
-Prefer:
-
-* simple classes
-* explicit logic
-* minimal indirection
-* clear ownership of behavior
-
-Avoid:
-
-* unnecessary patterns
-* speculative architecture
-* defensive boilerplate
-
----
-
-## Guiding Principle
-
-Prefer:
-
-**clear failure over hidden corruption**
-
-A bug should surface near its source rather than being silently ignored.
