PLAN-003: Migrate Scripts to New Secrets Paths

IMPLEMENTATION RULES: Before implementing this plan, read and follow:

• WORKFLOW.md - The implementation process
• PLANS.md - Plan structure and best practices

Status: Complete

Goal: Update all scripts in the repo that reference topsecret/ or secrets/ to use the new .uis.secrets/ paths, while maintaining backwards compatibility.

Last Updated: 2026-01-23

Branch: feature/secrets-migration

Prerequisites: PLAN-001 ✓ and PLAN-002 ✓ complete

Related: INVESTIGATE-secrets-consolidation.md

Note: PLAN-002 created paths.sh with base path detection functions. This plan extends that with backwards-compatible path resolution and deprecation warnings for topsecret/ paths.

---

Context: Contributor vs User

We are contributors - we update scripts in the repo to use new path conventions.

At runtime, these scripts run inside the container and access:

• /mnt/urbalurbadisk/.uis.secrets/ (user's secrets, mounted)
• /mnt/urbalurbadisk/.uis.extend/ (user's config, mounted)
• /mnt/urbalurbadisk/topsecret/ (old path, mounted for backwards compat)

The scripts we update need to:

1. Prefer new paths when available
2. Fall back to old paths for backwards compatibility
3. Warn users when old paths are detected

---

  OLD_SECRETS_BASE="/mnt/urbalurbadisk/topsecret"
  OLD_SSH_BASE="/mnt/urbalurbadisk/secrets"
  
  # Returns path to use, preferring new location
  get_secrets_base_path() {
    if [ -d "$NEW_SECRETS_BASE" ]; then
      echo "$NEW_SECRETS_BASE"
    elif [ -d "$OLD_SECRETS_BASE" ]; then
      warn_deprecated_path "$OLD_SECRETS_BASE" "$NEW_SECRETS_BASE"
      echo "$OLD_SECRETS_BASE"
    else
      echo "$NEW_SECRETS_BASE"  # Default to new
    fi
  }
  
  get_ssh_key_path() {
    # New: .uis.secrets/ssh/
    # Old: secrets/
  }
  
  get_kubernetes_secrets_path() {
    # New: .uis.secrets/generated/kubernetes/
    # Old: topsecret/kubernetes/
  }
  
  get_cloud_init_output_path() {
    # New: .uis.secrets/generated/ubuntu-cloud-init/
    # Old: cloud-init/
  }
  
  get_kubeconfig_path() {
    # New: .uis.secrets/generated/kubeconfig/
    # Old: (various locations)
  }
  
  get_tailscale_key() {
    # New: .uis.secrets/service-keys/tailscale.env
    # Old: topsecret/kubernetes/kubernetes-secrets.yml
  }
  
  get_cloudflare_token() {
    # New: .uis.secrets/service-keys/cloudflare.env

• Unit tests pass for path resolution (63 tests) ✓
• Backwards-compat tests pass (52 tests) ✓
• Kubeconfig merge playbook updated ✓
• No functionality broken during transition ✓

---

Files Created/Modified

Phase 1 (Complete):

• provision-host/uis/lib/paths.sh ✓ Extended (not uis-paths.sh - reused existing library)
• provision-host/uis/tests/unit/test-paths.sh ✓ Extended (63 tests)

Future Phases:

• topsecret/DEPRECATED.md (Phase 7)

Files to Modify

• All 24 scripts listed in Overview
• ansible/playbooks/04-merge-kubeconf.yml

---

Testing Strategy

For each script:

1. Test with new paths only (fresh setup)
2. Test with old paths only (legacy setup)
3. Test with both (migration in progress)

Use mock folders in test environment to simulate both scenarios.
