Frequently Asked Questions

The History page is your Git history, filtered through a BOM lens. Every commit in your repository appears here — we just highlight the ones that actually changed your Bill of Materials.

Each entry shows the essential Git commit information: author, clickable commit SHA (links to your repository), timestamp, branch badge, and commit message.

• BOM commits — Commits that affected your BOM get larger cards with one or more rows showing exactly what changed. These are the commits you'll spend most of your time reviewing.
• Non-BOM commits — Commits that didn't change any BOM files appear as compact single-line entries. They're part of your history, but visually muted so they don't distract. When several happen in a row, we collapse them into a summary — click Show to expand.

Each BOM card shows one row per affected BOM type:

• Schematic (SCH) — Components from your schematic design
• PCB — Components placed on the board layout
• Design State — Combined view showing which components are actually mounted

Colored dots give you a quick visual scan of what changed:

Card colors indicate special events:

• Green (Project Started) — The first commit where this BOM appeared
• Amber (Project Renamed) — You moved or renamed the project file
• Red (Parse Error) — We couldn't read a BOM file

Click the chevron (⌄) to see component-level changes. The expanded table shows each affected component with:

• Reference designator (R1, C5, U3, etc.)
• Value and part number
• What specifically changed

Each row has an icon indicating the type of change:

Each BOM row has action buttons:

The component amount displayed on the History view page has different meanings depending on the file type:

• SCH (Schematic) — The number of unique components you need to purchase
• PCB — The number of unique objects to be produced on the board
• Board Features — The number of objects you don't need to buy, such as fiducials and test points
