formatMeasuredExact now applies Math.fround to the parsed value before toFixed. The DOS QuickBASIC computed/stored these as single-precision floats, so the last-digit rounding at the .5 boundary follows single, not double, precision. Without it, double-precision toFixed flipped boundaries (9.9995 -> "9.999" vs golden "10.000"; 46.85 -> "46.9" vs "46.8"; .45 -> "0.5" vs "0.4"; 3.3325 -> "3.333" vs "3.332"). Verified each against the staged golden. STAGE 3 re-validation: FINAL-TEST CLEAN models 68 -> 85 (+17), mismatches 26 -> 9, cert matches 2123 -> 2206. Zero regression — every remaining dirty model was already dirty pre-fix; no previously-clean model flipped. The 9 remaining are NOT rounding: - 4 models (DSCA38-05/-1793/-19C/-19E): Supply Current retest data-vintage — the staged .TXT is an older test run than the DB latest-wins record; not a render bug, can't reconcile against an older sheet. - 5 models (DSCA39-01/02/05/07/1950): STAGE 1 template artifact — the footer note "Standard output load for test is 250 ohms." was mis-captured as a truncated parameter row. A renderer-side fix was attempted but emitted the note for all current-output models (regressed 24 clean -C models), so it was reverted; needs a targeted STAGE 1 extractor fix instead. Renamed dsca-clean68-models.json -> dsca-clean-models.json (now 85 models). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
ClaudeTools Bootstrap / Reinstall Guide
Complete instructions for backing up and restoring a ClaudeTools development environment on Windows 11.
Pre-Reinstall: Creating the Archive
Before wiping or reinstalling Windows, create a backup archive.
Option A: Automated Archive (Recommended)
Run the bootstrap script in archive mode:
cd D:\ClaudeTools\bootstrap
.\bootstrap.ps1 -Archive
This creates D:\ClaudeTools-backup.zip containing:
- The full ClaudeTools repository (excluding
node_modules,__pycache__,venv) - Claude configuration and memory from
C:\Users\<you>\.claude\
To specify a custom output path:
.\bootstrap.ps1 -Archive -ArchivePath "E:\Backups\claudetools-2026-03-17.zip"
Option B: Manual Archive
If the script is unavailable, manually zip these locations:
- ClaudeTools repository:
D:\ClaudeTools\(entire directory) - Claude memory and config:
C:\Users\<you>\.claude\(entire directory)
Copy the archive(s) to external storage (USB, NAS, cloud) before proceeding with the Windows reinstall.
What Does NOT Need Archiving
These are restored automatically by the bootstrap script:
- Git, Node.js, Python, Ollama (reinstalled via winget)
- npm global packages (reinstalled)
- Python pip packages (reinstalled)
- Ollama models (re-pulled)
- MCP server virtual environments (recreated)
Post-Reinstall: Running the Bootstrap
Step 1: Prepare the D: Drive
If D:\ClaudeTools was on a separate partition that survived the reinstall, skip to Step 2.
Otherwise, extract your archive:
# Extract the ClaudeTools repo to D:\
Expand-Archive -Path "E:\Backups\claudetools-2026-03-17.zip" -DestinationPath "D:\"
# Extract Claude config to your user profile
# (The archive contains a 'claude-config' folder - copy it to the right place)
Copy-Item -Path "D:\claude-config\*" -Destination "$env:USERPROFILE\.claude\" -Recurse -Force
Step 2: Run the Bootstrap Script
Open an elevated PowerShell (Run as Administrator):
Set-ExecutionPolicy Bypass -Scope Process -Force
D:\ClaudeTools\bootstrap\bootstrap.ps1
The script runs 9 phases and takes approximately 15-30 minutes depending on download speeds and Ollama model sizes.
Step 3: Advanced Usage
Run a single phase:
.\bootstrap.ps1 -OnlyPhase 4 # Only install Python packages
Skip specific phases:
.\bootstrap.ps1 -SkipPhase 5 # Skip Ollama model pulls (slow)
.\bootstrap.ps1 -SkipPhase 4,5 # Skip Python packages and Ollama models
Phase Reference
| Phase | What It Does | Duration |
|---|---|---|
| 1 | Install Git, Node.js, Python 3.13, Ollama via winget | 2-5 min |
| 2 | Install Claude Code CLI + global npm packages | 1-2 min |
| 3 | Clone or configure ClaudeTools git repository | <1 min |
| 4 | Install all Python pip packages globally | 3-5 min |
| 5 | Pull Ollama models (nomic-embed-text, llama3.1:8b, qwen2.5-coder:7b) | 5-15 min |
| 6 | Create MCP server venv and install dependencies | 1-2 min |
| 7 | Write Claude Code settings.json, copy commands, create directories | <1 min |
| 8 | Initialize GrepAI | <1 min |
| 9 | Verify all components are installed and working | <1 min |
Manual Steps (Cannot Be Automated)
These steps require interactive authentication or browser actions:
1. Authenticate Claude Code
claude
Follow the prompts to enter your Anthropic API key or log in via browser.
2. GitHub Personal Access Token
Edit D:\ClaudeTools\.mcp.json and set the GITHUB_PERSONAL_ACCESS_TOKEN value:
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_your_token_here"
}
Generate a new token at: https://github.com/settings/tokens
3. Claude-in-Chrome Extension
Install the Chrome extension manually:
- Open Chrome and navigate to the Chrome Web Store
- Search for "Claude in Chrome" (or install from the MCP extension source)
- Configure the extension to connect to your local MCP server
4. Restore Memory Files (If Needed)
If the bootstrap reports memory files are missing:
# Copy from your archive
Copy-Item -Path "E:\Backups\claude-config\projects\D--ClaudeTools\memory\*" `
-Destination "$env:USERPROFILE\.claude\projects\D--ClaudeTools\memory\" `
-Recurse -Force
5. Git Credentials
When you first git pull or git push to Gitea, you will be prompted for credentials. Use the Gitea username and password from credentials.md.
Verification Checklist
After bootstrap completes, verify manually:
git --versionreturns a versionnode --versionreturns v24.x or laterpython --versionreturns 3.13.xclaude --versionreturns a versionollama listshows all 3 modelsD:\ClaudeToolsexists and has.gitdirectoryD:\ClaudeTools\.mcp.jsonexistsD:\ClaudeTools\grepai.exeexistsC:\Users\<you>\.claude\settings.jsonexistsC:\Users\<you>\.claude\commands\has command files- Run

Troubleshooting
winget not found
Install "App Installer" from the Microsoft Store. It ships with Windows 11 but may need updating.
Node.js/Python not on PATH after install
Close and reopen your terminal, or run:
$env:Path = [System.Environment]::GetEnvironmentVariable("Path", "Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path", "User")
Ollama models fail to pull
Ensure the Ollama service is running:
ollama serve
Then retry:
.\bootstrap.ps1 -OnlyPhase 5
pip install fails for specific packages
Some packages (pywin32, opencv-python, pyzbar) require Visual C++ Build Tools. Install if needed:
winget install Microsoft.VisualStudio.2022.BuildTools
Then re-run Phase 4:
.\bootstrap.ps1 -OnlyPhase 4
GrepAI init requires interaction
Run manually:
cd D:\ClaudeTools
.\grepai.exe init
Select Ollama as the provider and nomic-embed-text as the embedding model.
SSL certificate errors with Gitea
The bootstrap configures http.sslVerify false automatically. If you still see errors:
cd D:\ClaudeTools
git config http.sslVerify false
