2026-04-21 — Mac Vault Setup & Remediation-Tool Validation

User

• User: Mike Swanson (mike)
• Machine: Mikes-MacBook-Air.local
• Role: admin

Session Summary

Completed full vault and remediation-tool setup on Mac from scratch. This session started with Howard's note requesting vault sync for remediation-tool, discovered and fixed critical bugs in get-token.sh, validated vault sync from Windows, and ended with complete vault setup on Mac enabling remediation-tool to work across all machines.

Key Accomplishments:

1. Fixed critical vault path variable collision bug in get-token.sh
2. Removed unnecessary guru-rmm submodule auto-update from sync script
3. Validated vault sync from Windows (all 5 SOPS files confirmed)
4. Completed full vault setup on Mac (SOPS, age, vault clone, token acquisition tested)
5. Created comprehensive VAULT-SETUP-GUIDE.md for future machine setups
6. Confirmed remediation-tool now works on Mac with 4/5 tiers functional

Why This Matters: Remediation-tool is now truly portable - works on Mac, Windows (DESKTOP-0O8A1RL), and ready for Howard's machines. Any team member can run breach checks, acquire tokens, and access vault secrets from any machine.

Timeline

09:00 - Initial Sync & Howard's Note

• Synced from Gitea, received Howard's message about Cascades spoofing hunt blocker
• Issue: Howard blocked on remediation-tool - needs 5 new-tier SOPS files in vault
• Issue: Howard's report showed vault auth blocked get-token.sh on ACG-Tech03L

09:15 - Vault Path Bug Discovery

• Tested remediation-tool scripts on Mac
• Bug Found: Variable name collision in get-token.sh
  • VAULT_PATH used for both SOPS file path AND vault root env var
  • Caused ERROR: vault not found at msp-tools/computerguru-*.sops.yaml
• Created .claude/URGENT-vault-path-bug.md for Windows session

09:30 - Sync Script Optimization

• Question from user: "Is guru-rmm submodule auto-update still necessary?"
• Answer: No - submodule location is fixed, auto-update creates noise
• Removed lines 68-72 from .claude/scripts/sync.sh (submodule update)
• Reduces commit noise from GuruRMM updates

18:00 - Windows Session (DESKTOP-0O8A1RL)

• Bug fixed: Variable collision resolved (VAULT_PATH → VAULT_ROOT_ENV)
• Bug fixed: Directory traversal corrected (4 levels up instead of 3)
• Vault sync validated: All 5 SOPS files confirmed in vault repo
• Token acquisition tested: All 5 tiers working on Windows
• Age key and Gitea password provided for Mac setup

19:00 - Mac Vault Setup

• Installed SOPS 3.12.2 via Homebrew
• Installed age 1.3.1 via Homebrew
• Configured age private key at ~/.config/sops/age/keys.txt
• Manual step: User cloned vault repo in real terminal (auth prompt required)
• Added vault_path to identity.json
• Issue found: vault.sh had Windows line endings (CRLF)
  • Fixed with: perl -pi -e 's/\r\n/\n/g' vault.sh
• Issue found: SOPS_AGE_KEY_FILE not set automatically
  • Added to ~/.zshenv for persistence
• Token acquisition tested: 4/5 tiers working (defender not consented in test tenant)

19:30 - Documentation

• Created .claude/VAULT-SETUP-GUIDE.md (522 lines)
• Comprehensive guide for Mac/Windows/Linux setup
• Includes all credentials, troubleshooting, quick setup for Howard
• Documents all issues encountered and solutions

Critical Bugs Fixed

Bug 1: Vault Path Variable Collision in get-token.sh

Severity: CRITICAL - Blocked all remediation-tool usage on all machines

Root Cause: Variable name collision introduced in vault portability commits (0a7cd6b, a86df11).

# PROBLEM: VAULT_PATH used for TWO different things

# Line ~40-70: VAULT_PATH stores SOPS file relative path
VAULT_PATH="msp-tools/computerguru-security-investigator.sops.yaml"

# Line ~87-95: VAULT_PATH ALSO used as env var for vault root
VAULT_ROOT="${VAULT_PATH:-}"  # BUG: Gets SOPS path, not vault root!

Result:

./get-token.sh cascadestucson.com investigator
→ ERROR: vault not found at msp-tools/computerguru-security-investigator.sops.yaml

Script checked if SOPS file path existed as a directory.

Fix Applied (commit 90f9d9e):

# Renamed env var override to avoid collision
VAULT_ROOT="${VAULT_ROOT_ENV:-}"

# Error message updated
[[ -z "$VAULT_ROOT" ]] && { echo "ERROR: vault_path not set in $IDENTITY_FILE and VAULT_ROOT_ENV env var not set" >&2; exit 3; }

Also fixed: Directory traversal depth (3 levels → 4 levels to reach repo root)

Why Windows worked before fix: Tokens were served from /tmp/remediation-tool/ cache (55 min TTL). First acquisition succeeded before bug was introduced, subsequent calls used cached tokens.

Bug 2: Submodule Auto-Update Creating Noise

Issue: sync script ran git submodule update --remote every sync Result: Frequent commits like M projects/msp-tools/guru-rmm Why unnecessary: Submodule location is fixed, not maintaining configuration Fix: Removed lines 68-72 from .claude/scripts/sync.sh

Issues Encountered & Solutions

Issue 1: Git Auth Blocked in Claude Code Shell

Problem: git clone vault failed with "Device not configured" Cause: Git cannot prompt for password in Claude Code terminal Solution: User cloned in real Terminal.app with password prompt Documented in: VAULT-SETUP-GUIDE.md troubleshooting

Issue 2: vault.sh Line Endings

Problem: env: bash\r: No such file or directory Cause: Vault cloned from Windows has CRLF line endings Solution: perl -pi -e 's/\r\n/\n/g' ~/vault/scripts/vault.sh Documented in: VAULT-SETUP-GUIDE.md troubleshooting

Issue 3: SOPS Age Key Not Found

Problem: vault.sh failed with "Failed to get the data key" Cause: SOPS_AGE_KEY_FILE environment variable not set Solution: Added to ~/.zshenv for persistence Documented in: VAULT-SETUP-GUIDE.md troubleshooting

Issue 4: Variable Collision in get-token.sh

Problem: Token acquisition failed on all machines Cause: VAULT_PATH variable name reused for two purposes Solution: Renamed env var to VAULT_ROOT_ENV (commit 90f9d9e) Documented in: URGENT-vault-path-bug.md, session log

---

Key Decisions & Rationale

Decision 1: Remove Submodule Auto-Update

Question: "Is guru-rmm submodule reconfigure still necessary?" Decision: Remove it from sync script Rationale:

• Submodule location is fixed at projects/msp-tools/guru-rmm
• Auto-update creates commit noise every time GuruRMM has new commits
• Not maintaining configuration, actively updating pointer
• Manual update available: git submodule update --remote

Decision 2: Vault Setup on Mac is Required

Question: "Do you have the age key?" (implying: do we need Mac vault?) User Statement: "Remediation tool needs to work on any machine" Decision: Complete full vault setup on Mac Rationale:

• Tool must be portable across all team machines
• Mac is used for work, needs remediation-tool capability
• Sets precedent for future machine setups
• Validates portability improvements

Decision 3: Document Everything in VAULT-SETUP-GUIDE.md

Decision: Create comprehensive 522-line setup guide Rationale:

• Encountered multiple platform-specific issues (line endings, env vars, auth)
• Howard needs setup on ACG-Tech03L and HOWARD-HOME
• Future machines will need same setup
• Preserves solutions to all issues in one place

Defender failure details:

ERROR: AADSTS7000229 — app not consented in tenant 032b383e-96e4-491b-880d-3fd3295672c3
Service principal not authorized in this tenant.
Consent URL: https://login.microsoftonline.com/032b383e-96e4-491b-880d-3fd3295672c3/adminconsent?client_id=dbf8ad1a-54f4-4bb8-8a9e-ea5b9634635b&redirect_uri=https://azcomputerguru.com

This is expected - grabblaw.com has only consented Security Investigator, User Manager, and Tenant Admin apps.
