The first hour
An instrument leaves the supplier’s workshop and begins to accumulate a history Meridian must keep.
The table acquires an instrument
For several intervals the metrology assembly existed here as a sequence of offers and requirements. On December 21 it leaves the supplier’s workshop. The intake note records the handover, the original mounting and the narrow permission for its first powered hour. The space elevator remains an ambition far beyond this table, but its displacement work now has an instrument with a local history.
That history begins with a change of eleven micrometres while no stage travel is commanded. Without a stationary comparison, the number belongs to several possible accounts. It is retained before anyone can decide which account it will support. The last two readings agree; the first one still matters.
The part that survives
In the recovery note, a missing reply leaves the decision on the other side of an interruption. Recovering it requires naming the request and payload it already belongs to. The model becomes more useful when it can say what a retry is allowed to retrieve, rather than calling every retry a new beginning.
The echo study shifts a command one sample and changes what the earlier screen can see. It is a small displacement in a short synthetic array. The consequence is specific: the next electrical experiment must include timing offsets, and the record must keep the sources before any subtraction.
After arrival
The assembly’s arrival shortens one distance and exposes another. There is still no separately held stationary reference and no permission to load the strip. Meridian’s next work is neither to celebrate the display nor to remove its inconvenient first value, but to make a comparison capable of saying what moved.
