+# Stash System
+
+Sistema de gestão de conflitos e backups para vibe-devtools, inspirado no `git stash`.
+
+## Overview
+
+O Stash System permite que você gerencie arquivos durante instalação/atualização de packages com controle total sobre o que sobrescrever, manter ou arquivar.
+
+### Features
+
+- ✅ Detecção automática de conflitos via SHA-256 hash
+- ✅ Backup seguro com full copy (não patch)
+- ✅ Comandos CLI familiares (inspirados no git stash)
+- ✅ FILO ordering com renumeração automática
+- ✅ Logging completo em JSONL
+- ✅ Dry-run support
+- ✅ Integration com install e update commands
+
+## Quick Start
+
+### Install com Detecção de Conflitos
+
+```bash
+npx vibe-devtools install @vibe-devtools/basic
+```
+
+Se houver conflitos, você verá:
+
+```
+⚠️  Conflicts detected (3 files)
+
+  1. vibes/configs/constitution.md
+     Local:   abc123...
+     Package: def456...
+
+How to resolve conflicts?
+  [1] Overwrite with package version
+  [2] Stash local and install package
+  [3] Cancel installation
+```
+
+Escolha opção 2 para criar backup automático.
+
+### Update com Stash
+
+```bash
+npx vibe-devtools update @vibe-devtools/basic --latest
+npx vibe-devtools update @vibe-devtools/basic --version 1.0.3
+npx vibe-devtools update @vibe-devtools/basic --dry-run
+```
+
+### Dry Run
+
+Preview mudanças sem instalar:
+
+```bash
+npx vibe-devtools install @vibe-devtools/basic --dry-run
+```
+
+## Comandos Stash
+
+### List
+
+Lista todos os stashes:
+
+```bash
+npx vibe-devtools stash list
+```
+
+Output:
+```
+stash{0} - @vibe-devtools/basic
+  install • 2025-10-23 14:30 • 3 files
+
+stash{1} - manual
+  manual • 2025-10-23 15:45 • 2 files
+
+Total: 2 stashes
+```
+
+### Show
+
+Mostra detalhes de um stash:
+
+```bash
+npx vibe-devtools stash show 0
+```
+
+### Apply
+
+Aplica stash (mantém no histórico):
+
+```bash
+npx vibe-devtools stash apply 0
+```
+
+### Pop
+
+Aplica stash e remove do histórico:
+
+```bash
+npx vibe-devtools stash pop 0
+```
+
+### Remove
+
+Remove um stash:
+
+```bash
+npx vibe-devtools stash remove 0
+```
+
+### Diff
+
+Mostra diferenças entre stash e arquivos atuais:
+
+```bash
+npx vibe-devtools stash diff 0
+npx vibe-devtools stash diff 0 --editor  # abre no IDE
+```
+
+### Save
+
+Cria stash manual:
+
+```bash
+npx vibe-devtools stash save file1.ts file2.ts
+npx vibe-devtools stash save  # prompt interativo
+```
+
+### Clear
+
+Remove todos os stashes:
+
+```bash
+npx vibe-devtools stash clear
+npx vibe-devtools stash clear --force  # sem confirmação
+```
+
+## Architecture
+
+### Components
+
+- **HashCalculator**: SHA-256 hash calculation
+- **StashLogger**: JSONL logging system
+- **StashManager**: Core lifecycle management
+- **ConflictDetector**: Hash-based conflict detection
+- **ConflictResolver**: CLI prompts & diff display
+
+### Storage
+
+```
+~/.vibes/stash/
+├── index.json          # Lista de stashes
+├── stash-0/
+│   ├── metadata.json   # Metadata do stash
+│   └── files/          # Full copy dos arquivos
+└── stash-1/
+    ├── metadata.json
+    └── files/
+```
+
+### Logging
+
+```
+~/.vibes/logs/stash.log
+```
+
+Format: JSONL (1 JSON per line)
+
+## Technical Details
+
+### Hash Algorithm
+
+SHA-256 via Node.js crypto (nativo)
+
+### Storage Strategy
+
+Full copy (não patch) para:
+- Simplicidade e confiabilidade
+- Suporte a qualquer tipo de arquivo
+- Sempre funciona (não corrompe)
+
+### Ordering
+
+FILO (First In Last Out) com renumeração:
+- `stash{0}` é sempre o mais recente
+- Após `pop` ou `remove`, IDs são renumerados
+- Igual ao `git stash`
+
+## Error Handling
+
+### Permission Denied
+
+Se erro de permissão em `~/.vibes/stash/`:
+
+```bash
+sudo chown -R $USER ~/.vibes
+```
+
+### Stash Corrupted
+
+Sistema valida integridade via hash antes de aplicar. Se corrompido:
+
+```bash
+npx vibe-devtools stash remove <stash-id>
+```
+
+### Disk Full
+
+Libere espaço ou:
+
+```bash
+npx vibe-devtools stash clear
+```
+
+## Performance
+
+- Hash calculation: < 100ms (arquivos < 1MB)
+- Stash creation: < 1s (< 100 arquivos)
+- Stash apply: < 1s (< 100 arquivos)
+
+## Dependencies
+
+- `inquirer@^9.2.0` - CLI prompts
+- `diff@^5.1.0` - Diff display
+
+## Compatibility
+
+- Node.js >= 18.0.0
+- Works on: macOS, Linux, Windows
