# ✅ SOLUCIÓN: Syntaxis como TaskService Integrado

**Fecha**: 2025-11-20
**Estado**: Arquitectura correcta basada en patrones existentes
**Referencia**: taskservs (databases), provctl (stage1-extended-definitions)

---

## 🎯 El Problema (Versión Final)

### ¿Por qué Dockerfile o docker-compose NO son suficientes?

```
Dockerfile/docker-compose definen:
  ✅ Cómo empacar (imagen + dependencias)
  ✅ Qué puertos exponer
  ✅ Qué variables de entorno
  ✅ Cómo iniciar el servicio

Pero NO definen:
  ❌ Cómo GESTIONAR el ciclo de vida (systemd, provctl)
  ❌ Cómo VALIDAR salud del servicio
  ❌ Cómo ORQUESTAR múltiples máquinas
  ❌ Cómo INTEGRAR con provisioning
  ❌ Cómo ESCALAR en diferentes contextos (local, dev, prod)
  ❌ Requisitos de INFRA (networking, storage, secrets)
```

### La Solución: Tres capas coherentes

│ Lenguaje: KCL o YAML (readable, maintainable)              │
│ Consumidor: syntaxis installer (para ofrecerpresets)       │
└─────────────────────────────────────────────────────────────┘

INTEGRACIÓN:
  Capa 1 → provisioning la ve como taskserv importable
  Capa 2 → provctl la puede gestionar localmente
  Capa 3 → installer ofrece presets (local/dev/prod)
```

## 🔧 CAPA 2: Gestión Local con provctl

### Cómo provctl lo consumiría

```bash
# Developer corre
provctl config apply --from-file /provctl/examples/syntaxis-local-dev.toml

# O desde taskserv (si se integra)
provctl config apply --from-taskserv syntaxis --mode dev

# Resultado:
# - Crea configuración local
# - Inicia servicios con systemd/launchd
# - Monitorea health
# - Proporciona CLI para control
```

all_presets = [

### Uso: syntaxis installer

```rust
// syntaxis/core/crates/cli/src/installer.rs

pub fn list_presets() -> Vec<DeploymentPreset> {
    // Load from configs/deployment-presets.kcl
    KCL::load("configs/deployment-presets.kcl")
        .all_presets
}

pub fn install(preset: &str) -> Result<()> {

    println!("📦 Installing preset: {}", preset_config.name);
    println!("   {}", preset_config.description);
    println!("   Services: {:?}", preset_config.services);
    println!("   Manager: {}", preset_config.manager);

    match preset_config.manager {
        "manual" => {
            println!("Manual setup. Follow these steps:");
            print_manual_guide(&preset_config);
        }
        "provctl" => {
            if detect_provctl()? {

        }
        "provisioning" => {
            println!("Provisioning required. Integrating...");
            integrate_with_provisioning(&preset_config)?;
        }
        _ => {}
    }

    Ok(())
}
```

### Resultado: Coherencia entre capas

```
syntaxis installer
  ↓
Lee: deployment-presets.kcl
  ├─ "local" → manual setup
  ├─ "dev" → provctl (if available)
  ├─ "staging" → provisioning
  └─ "production" → provisioning + monitoring
     ↓
  Para cada preset:
  ├─ Lee requisitos (surrealdb, nats, etc)
  ├─ Genera config provctl (si manager="provctl")
  ├─ O integra con provisioning (si manager="provisioning")
  └─ Ofrece comandos para cada paso
```

---

## 🔗 Cómo Se Conectan Las Tres Capas

### CAPA 1: Definición en provisioning

```kcl
# provisioning/extensions/taskservs/development/syntaxis/kcl/syntaxis.k

schema Syntaxis:
    version: str
    deployment_mode: str
    database: { type: str, ... }
    health_checks: { ... }
```

### CAPA 2: Configuración en provctl

```toml
# provctl/examples/syntaxis-local-dev.toml

[service]
name = "syntaxis-api"
binary = "/usr/local/bin/syntaxis-api"
args = ["--bind", "127.0.0.1:3000"]

[[health_checks]]
type = "http"
endpoint = "http://127.0.0.1:3000/health"
```

### CAPA 3: Presets en syntaxis

```kcl
# syntaxis/configs/deployment-presets.kcl

preset_dev: DeploymentPreset = {
    manager = "provctl"
    requirements = ["surrealdb"]
    services = { "api": True, "tui": True, ... }
}
```

### Flujo de integración

```
Developer usa syntaxis installer:
  ↓
installer lee deployment-presets.kcl
  ↓
Elige preset "dev":
  ├─ manager = "provctl" → installer llama provctl
  ├─ requirements = ["surrealdb"] → verificar disponible
  └─ services = { "api": True, ... } → generar config
     ↓
provctl aplica config (desde syntaxis-local-dev.toml)
  ├─ Genera config systemd/launchd
  ├─ Inicia servicios
  ├─ Monitorea health
  └─ Proporciona CLI para control
     ↓
Si necesita provisioning (preset "prod"):
  ├─ installer detecta provisioning
  ├─ syntaxis se importa como taskserv
  ├─ provisioning ve requisitos (postgres, nats, etc)
  ├─ provisioning orchestra todo
  └─ Resultado: Full stack en producción
```

## 📊 Comparación: Antes vs Después

| Aspecto | TOML Compilado | Solución (3 Capas) |
|---------|---|---|
| **Definición** | TOML → catalog.rs → ingestionable | KCL taskserv (como postgres) |
| **Gestión local** | ¿Cómo ejecutar? | provctl TOML config (como minimal-app) |
| **Presets** | No existen | KCL en syntaxis (deployment-presets.kcl) |
| **Cambios requieren** | Recompilación | Solo guardar archivo |
| **Consumible por** | provisioning tools | provisioning, provctl, installer |
| **Escalabilidad** | Acoplado a Rust | Modular, extensible |
| **Developer experience** | "¿Qué es este TOML?" | "Elige preset: local, dev, staging, prod" |

---

## ✅ Beneficios

### Para Developer
```
✅ Elige preset (local, dev, staging, prod)
✅ Instalador automático lo detecta todo
✅ Corre syntaxis: local manual, dev con provctl, prod con provisioning
✅ NO ve TOML compilado, ve presets legibles
```

### Para provisioning
```
✅ syntaxis es un taskserv como cualquier otro (postgres, kubernetes, etc)
✅ Lo importa como dependency externo
✅ Lo orquesta en contexto de infra
✅ Sabe requisitos (qué bases de datos, etc) del schema KCL
```

### Para provctl
```
✅ Lee config TOML como cualquier otro servicio
✅ Puede gestionar syntaxis localmente
✅ Puede gestionar sintaxis remotamente (SSH)
✅ Health checks automáticos
```

### Para installer
```
✅ Ofrece presets claros
✅ Detección inteligente (provisioning? provctl? manual?)
✅ Configura automáticamente
✅ Fallback gracioso con guía manual
```

---

## 🚀 Implementación (Roadmap Mínimo)

### Paso 1: Crear taskserv en provisioning
```
1. Crear estructura:
   provisioning/extensions/taskservs/development/syntaxis/

2. Definir KCL:
   - syntaxis.k (schema principal)
   - dependencies.k (requisitos)

3. Agregar ejemplos:
   - install-syntaxis.sh
   - env-syntaxis.j2
```

### Paso 2: Crear config provctl
```
1. Crear: provctl/examples/syntaxis-local-dev.toml

2. Define:
   - Service principal (syntaxis-api)
   - Health checks
   - Variables de entorno
   - Secretos
```

### Paso 3: Crear presets en syntaxis
```
1. Crear: syntaxis/configs/deployment-presets.kcl

2. Define:
   - preset_local
   - preset_dev
   - preset_staging
   - preset_production
```

### Paso 4: Integrar con installer
```
1. Extender syntaxis installer para:
   - Leer presets
   - Detectar provctl/provisioning
   - Aplicar configuración automática
```

## 📌 Resumen

**El problema**: TOML compilado es ingestionable, requiere recompilación, no es escalable.

**La solución**: Tres capas coherentes:
1. **CAPA 1 (provisioning)**: TaskService KCL (como postgres)
2. **CAPA 2 (provctl)**: Config TOML (como minimal-app)
3. **CAPA 3 (syntaxis)**: Presets KCL (local/dev/staging/prod)

**Resultado**:
- Developer elige preset
- Installer detecta contexto
- Se configura automáticamente
- Funciona sin Docker/compose requirements adicionales
- Integrable con provisioning y provctl

**Por qué funciona**:
- Sigue patrones EXISTENTES en provisioning y provctl
- No inventa nuevos formatos
- Reutiliza código/infraestructura existente
- Escalable a otros proyectos (como "taskservs externo")
