Table reconstruction on save is part of the artifact editing skill, whose registration check is false.

What

Saving a spreadsheet artifact now reconstructs the underlying table from the live grid rather than saving the on-screen markup, and scratch rows or columns you typed into become real data. Part of the artifact editing skill, whose registration check is false in this build.

Details
  • Generated chrome is dropped on save: row-number and column-letter cells, sort chips, filter stats, and filler, selection and formula classes.
  • Data rows are re-sorted back to their authored order, totals return to a table footer, and the column count is extended to cover any scratch column with non-empty text.
  • Formula cells are saved from their stored source rather than the displayed value, with a new guard so a cell being edited in the formula bar still contributes its source.
  • The formula bar commits its pending edit before a save and disables itself while the page is inert; sort direction is carried across the save-triggered reload.
  • The skill text no longer tells authors to write twenty empty rows; scratch padding becomes data on save instead.
Evidence

A save carries the AUTHORED table, rebuilt from the live grid so

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
