resolve.rs::written read its operands at Enter: the record and measure
from the cell under the cursor, and the basis from claim(), i.e. the
version current at commit. So a HideItem from another client that
renumbered the rows under an open editor sent the write to whichever
cell the cursor then named (8xq0), and a write by another client to the
record while the editor was open was silently overwritten instead of
refused RecordMoved (xz2z, 0j0f's rule on the keyboard door).
The fix reuses #221's capture rather than adding a second one.
ClientState::opened becomes OpenedCell { record, target, version,
document_generation }, where OpenedTarget is Value { measure } or
Coordinate { category }. settle_opened captures a Record cell as a
Value target, and written builds the RecordCell and the claim_as_read
basis from it. With no capture while the host has yet to answer this
client's own last write, the commit declines with the rename's "still
waiting" status.
Red first: both round-trip probes failed on gh/main 202e7eac and on
#221's head 39821d5f. Unit-test fixtures that set Editing by assignment
now open the editor through the fold, which is where the capture is
taken.
Stacked on #221 (fix/fdk1-coordinate-rename).
