## Architecture
### Spec-Agnostic Design
The security system is **completely spec-agnostic** - it doesn't depend on any specific spec implementation. Instead, each spec (restheadspec, funcspec, resolvespec) implements its own security integration by adapting to the `SecurityContext` interface.
```
┌─────────────────────────────────────┐
│ Security Package (Generic) │
│ - SecurityContext interface │
│ - Security providers │
│ - Core security logic │
└─────────────────────────────────────┘
▲ ▲ ▲

│Adapts │ │ Adapts │ │ Adapts │
│to │ │ to │ │ to │
│Security│ │ Security │ │ Security │
│Context │ │ Context │ │ Context │
└────────┘ └──────────┘ └───────────┘
```
**Benefits:**
- ✅ No circular dependencies
- ✅ Each spec can customize security integration
- ✅ Easy to add new specs
- ✅ Security logic is reusable across all specs
### Core Interfaces
The security system is built on three main interfaces:
@ -113,6 +146,28 @@ type SecurityProvider interface {
}
```
#### 4. SecurityContext (Spec Integration Interface)
Each spec implements this interface to integrate with the security system:
```go
type SecurityContext interface {
GetContext() context.Context
GetUserID() (int, bool)
GetSchema() string
GetEntity() string
GetModel() interface{}
GetQuery() interface{}
SetQuery(interface{})
GetResult() interface{}
SetResult(interface{})
}
```
**Implementation Examples:**
- `restheadspec`: Adapts `restheadspec.HookContext``SecurityContext`
- `funcspec`: Adapts `funcspec.HookContext``SecurityContext`
- `resolvespec`: Adapts `resolvespec.HookContext``SecurityContext`

**Key Points:**
- Security package is spec-agnostic and provides core logic
- Each spec registers its own hooks that adapt to SecurityContext
- Security rules are loaded once and cached for the request
- Row security is applied to the query (database level)
- Column security is applied to results (application level)

The main changes:
1. Security package no longer knows about specific spec types
2. Each spec registers its own security hooks
3. More flexible - same security provider works with all specs
