# Installation System Overview & Summary

**Quick Answer to:** "How we install targets with configs and wrappers?"

---

## TL;DR (Too Long; Didn't Read)

**Your Question:** "How we install targets with configs and wrappers?"

**Answer:**
Currently, syntaxis binaries install without their configurations. We need to:
1. Deploy configuration templates during installation
2. Create wrapper scripts to manage environment setup
3. Track installations in a manifest

This enables a seamless experience: **One command to install, binaries just work.**

---

## What This Is About

### Problem
```
Current state:
  $ just scripts-install
  ✅ Binaries installed

  $ syntaxis-api
  ❌ Error: Config not found

User must manually:
  1. Find config templates
  2. Copy them to correct location
  3. Edit configurations
  4. Set environment variables
  5. Run binary
```

### Solution
```
After implementation:
  $ just scripts-install
  ✅ Binaries installed
  ✅ Configs deployed
  ✅ Wrappers created
  ✅ Manifest tracked

  $ syntaxis-api
  ✅ Config found automatically
  ✅ Environment setup automatically
  ✅ Server running

Result: One command. Everything works.
```

## Key Components

### 1. Configuration Templates
```
syntaxis/
├── syntaxis-api-config.template.toml          ✅ Main config
└── configs/features/
    ├── auth.toml.template                      ✅ Existing
    ├── database.toml.template                  ✅ Existing
    ├── cache.toml.template                     ✅ Existing
    ├── health.toml.template                    ✅ Existing
    ├── metrics.toml.template                   ✅ Existing
    ├── multi_tenant.toml.template              ✅ Existing
    ├── rate_limit.toml.template                ✅ Existing
    ├── projects.toml.template                  ✨ NEW (Phase 1)
    ├── tasks.toml.template                     ✨ NEW (Phase 1)
    ├── phases.toml.template                    ✨ NEW (Phase 1)
    └── audit.toml.template                     ✨ NEW (Phase 1)
```

### 2. Installation Infrastructure
```
scripts/
├── install-cli.nu              ✅ Existing (needs config deployment)
├── manifest.nu                 ✅ Existing (tracks installations)
└── common/find-config.nu       ✅ Existing (discovers configs)
```

### 3. Configuration Locations
```
~/.config/core/  ← Where configs end up after install
├── syntaxis-api.toml
└── features/
    ├── auth.toml
    ├── database.toml
    ├── projects.toml           ← NEW
    ├── tasks.toml              ← NEW
    ├── phases.toml             ← NEW
    └── audit.toml              ← NEW

.syntaxis/           ← Where manifest lives
└── manifest.toml               ← Tracks what's installed
```

### 4. Wrapper Scripts (Phase 2+)
```
~/.cargo/bin/
├── workspace              ← Wrapper script (finds config, sets env)
├── workspace.real         ← Actual binary
├── syntaxis-tui          ← Wrapper script
├── syntaxis-tui.real     ← Actual binary
├── syntaxis-api          ← Wrapper script
└── syntaxis-api.real     ← Actual binary
```

## Installation Flow

### Before (Current)
```
User: just scripts-install
  → Compiles workspace
  → Installs binaries to ~/.cargo/bin/
  → That's it!

Result: Binaries installed, configs nowhere, doesn't work
```

### After Phase 1 (Configuration Deployment)
```
User: just scripts-install
  → Compiles workspace
  → Installs binaries to ~/.cargo/bin/
  → Copies config templates to ~/.config/core/
  → Creates manifest tracking

Result: Binaries + configs installed, still doesn't run (needs wrapper)
```

### After Phase 2 (Wrapper Scripts)
```
User: just scripts-install
  → Compiles workspace
  → Installs binaries to ~/.cargo/bin/
  → Copies config templates to ~/.config/core/
  → Creates wrapper scripts
  → Creates manifest tracking

Result: One command. Binaries work. Configs found automatically.
```

## Key Decisions Made

### ✅ Configuration Location: `~/.config/core/`
- Follows XDG Base Directory Specification
- Per-user configuration
- Separates code from config
- Works on all platforms (Linux, macOS, Windows)

### ✅ Configuration Format: TOML
- Already used in workspace
- Human-readable
- Serde validation support
- Feature-specific configs easy to compose

### ✅ Manifest Location: `.syntaxis/manifest.toml`
- Version-controlled
- Central installation tracking
- Clear audit trail
- Easy to query

### ✅ Phased Approach: 4 phases
- Phase 1: Deployments
- Phase 2: Wrappers
- Phase 3: Manifest enhancement
- Phase 4: Documentation
- Risk reduction, incremental value

### ✅ Wrapper Language: NuShell
- Consistent with workspace scripts
- Cross-platform
- Rich scripting capabilities
- Team standard

---

## Risks & Mitigation

| Risk | Mitigation |
|------|-----------|
| **Config format changes break existing setups** | Version tracking in manifest, migration guide |
| **Users confused about config location** | Clear documentation, installation guide |
| **Wrappers don't work on all platforms** | Test on Linux, macOS, Windows |
| **Performance impact from wrapper overhead** | Negligible (only on startup) |
| **Breaking existing installations** | Wrapper falls back to old behavior if needed |

---

## Success Metrics

After Phase 1:
- ✅ Config templates deployed automatically
- ✅ All 11 config templates available
- ✅ Manifest tracks installations
- ✅ Documentation complete
- ✅ Zero regressions in tests

After Phase 2:
- ✅ Wrapper scripts work on all platforms
- ✅ Environment setup automatic
- ✅ Config discovery works
- ✅ Integration tests passing

After Phase 4:
- ✅ Complete documentation
- ✅ User can install in < 2 minutes
- ✅ Setup works for 95%+ of users
- ✅ Troubleshooting guide covers common issues

## Questions Answered

### Q: Why is this needed?
**A:** Current users must manually copy and configure templates. This creates friction, errors, and confusion.

### Q: How long will it take?
**A:** Phase 1 is 4-5 hours. Full implementation (Phases 1-4) is 6-8 weeks.

### Q: Do we have to do all 4 phases?
**A:** Phase 1 alone provides significant value. Later phases enhance the experience.

### Q: Will this break existing installations?
**A:** No. This is purely additive. New installations get configs, old ones still work.

### Q: Can we do Phase 2 before Phase 1?
**A:** No, Phase 1 must come first. Wrappers need configs to find.

### Q: What about Windows users?
**A:** NuShell works on Windows. Config location uses standard Windows paths.
