What is the speed of light in a vacuum, in metres per second? Give the standard textbook value.
baseline PersonalAssistant as shipped — harness runs post-hoc over the reply vs flagOn PersonalAssistant with the one-loop harness-driven proposerbaseline — controlflagOn — candidate299,792,458 m/s (exact, by definition). The common textbook approximation is 3.00 × 10⁸ m/s.
The speed of light in a vacuum is exactly **299,792,458 metres per second** (often approximated as 3 × 10⁸ m/s). This value is exact by definition, since the metre is defined in terms of it.

The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
