Coverage gaps
- Exact model-family pages remain gated until an official or manual-backed source supports the model-specific wording.
- Parts and service handoffs are not shown as recommendations until the source context is strong enough.
How this guide should be used
- Use the source links to verify the original manufacturer context.
- Check model notes before treating a display code as universal.
- Prefer safe first checks before any disassembly or parts decision.
Current limitations
- Manufacturer guidance can differ by model family and region.
- Alias/display variants are only added when the source supports them.
- Manual-backed model detail is planned but not bulk-generated.
