@lilith/vault-setup-client

Manage vault symlink and macOS Keychain storage for secret management.

Features

• Vault symlink management: Create ~/.vault/ → project vault symlink
• macOS Keychain integration: Store/retrieve secrets securely
• Symlink verification: Check vault accessibility and target
• CLI and programmatic API

Installation

pnpm add @lilith/vault-setup-client

Usage

CLI

# Create vault symlink
npx @lilith/vault-setup-client link \\
  --project ~/Code/@applications/@lilith/lilith-platform

# Verify vault access
npx @lilith/vault-setup-client verify

# Store secret in Keychain (macOS only)
npx @lilith/vault-setup-client keychain-store \\
  --service restic-backup \\
  --account lilith-platform-workstations \\
  --password CWPVvKALTwyJfbdVE3oIq7L8Wc7MH4Pz

# Retrieve secret from Keychain
npx @lilith/vault-setup-client keychain-get \\
  --service restic-backup \\
  --account lilith-platform-workstations

Programmatic API

import { setupVaultSymlink, verifyVaultAccess, storeInKeychain, retrieveFromKeychain } from '@lilith/vault-setup-client'

// Create vault symlink
const symlinkResult = await setupVaultSymlink(
  '~/Code/@applications/@lilith/lilith-platform'
)

if (symlinkResult.success) {
  console.log(`✅ Symlink: ${symlinkResult.symlinkPath} → ${symlinkResult.targetPath}`)
}

// Verify vault access
const verification = await verifyVaultAccess()
console.log(`Vault accessible: ${verification.accessible}`)

// Store in Keychain (macOS only)
const storeResult = await storeInKeychain({
  service: 'restic-backup',
  account: 'lilith-platform-workstations',
  password: 'CWPVvKALTwyJfbdVE3oIq7L8Wc7MH4Pz',
})

// Retrieve from Keychain
const retrieveResult = await retrieveFromKeychain('restic-backup', 'lilith-platform-workstations')
if (retrieveResult.success) {
  console.log(`Password: ${retrieveResult.password}`)
}

Vault Architecture

Why Symlink?

Problem: Circular dependency with backups

• We backup ~/Code using restic
• To restore ~/Code, we need the restic password
• If password only exists in ~/Code/.../vault/, we can't restore without it!

Solution: Symlink + dual backup paths

1. Primary storage in project vault: lilith-platform/vault/
2. Convenient access via symlink: ~/.vault/ → project vault
3. Backed up via both Code (5min) + dotfiles (12hr)

Disaster Recovery Flow:

# 1. Restore dotfiles first (includes ~/.vault/ symlink)
restic -r rest:http://10.0.0.11:8000/$(hostname)-dotfiles restore latest --target ~/

# 2. Use vault password to restore Code
export RESTIC_PASSWORD_FILE=~/.vault/restic-password.txt
restic -r rest:http://10.0.0.11:8000/$(hostname)-code restore latest --target ~/

# 3. Full recovery complete (vault + code + dotfiles)

macOS Keychain

Why Keychain?

Defense-in-depth: If all backups fail, restic password is stored in macOS Keychain on MacBook.

Commands

# Store password
security add-generic-password \\
  -s restic-backup \\
  -a lilith-platform-workstations \\
  -w CWPVvKALTwyJfbdVE3oIq7L8Wc7MH4Pz \\
  -U

# Retrieve password
security find-generic-password \\
  -s restic-backup \\
  -a lilith-platform-workstations \\
  -w

# View in GUI
open /System/Applications/Utilities/Keychain Access.app
# Search for "restic-backup"

API

setupVaultSymlink(projectPath: string): Promise<SymlinkResult>

Create ~/.vault/ → <projectPath>/vault/ symlink.

Returns:

• success: Whether setup succeeded
• symlinkPath: Symlink path (~/.vault/)
• targetPath: Target path (<project>/vault/)
• error: Error message if failed

verifyVaultAccess(vaultPath?: string): Promise<VerificationResult>

Verify vault is accessible.

Parameters:

• vaultPath: Vault path to check (default: ~/.vault/)

Returns:

• accessible: Whether vault is readable
• vaultPath: Path checked
• isSymlink: Whether it's a symlink
• targetPath: Symlink target (if applicable)
• error: Error message if not accessible

storeInKeychain(secret: KeychainSecret): Promise<KeychainResult>

Store secret in macOS Keychain.

Parameters:

• secret.service: Service name (e.g., "restic-backup")
• secret.account: Account name (e.g., "lilith-platform-workstations")
• secret.password: Password to store

Returns:

• success: Whether operation succeeded
• error: Error message if failed

Note: macOS only - returns error on other platforms

retrieveFromKeychain(service: string, account: string): Promise<KeychainResult>

Retrieve secret from macOS Keychain.

Parameters:

• service: Service name
• account: Account name

Returns:

• success: Whether operation succeeded
• password: Retrieved password
• error: Error message if failed

Requirements

• macOS: Required for Keychain operations (symlink works on all platforms)
• Project vault: Target project must have vault/ directory

Integration

Works with @lilith/vault-setup-backup for encrypted backups and @lilith/restic-setup-client for automated backups.
