Whether the G3 battlecruisers were laid down

Were the G3 battlecruisers actually laid down, or were they only paper plans?

At least two appear to have entered initial construction, though the exact status of all four remains debated.

The question sits inside a continuing historical dispute about what counts as being laid down. The documentary material discussed supports real initial construction activity. The status of all four ships is less certain, though at least two appear to have reached this phase. Contracts, prepared materials, and work on the slip can be described differently in later summaries, which keeps the conclusion appropriately qualified.
