Why it matters
Why this page matters in the wider system.
Body shape, preferences and garment behaviour all evolve, and a fit system that cannot remember that evolution will keep solving the same problem badly. Without memory, every fitting starts from zero and every operator repeats the same discovery work the previous one already did. Worse, a single measurement carries no confidence interval: a tailor receiving one number cannot tell whether it is stable, drifting or simply wrong. With memory, the record answers questions no snapshot can — whether a change is a trend or a fluctuation, which garments have worked and which have not, and which of a wearer's dimensions are volatile enough to need re-checking before the next commission.
Version-controls body measurements and fit-relevant observations, so no entry overwrites another.
Attaches time, operator and garment context to every change, which is what makes a later reading interpretable.
Distinguishes a re-measurement from a body change by comparing the new entry against the established trend rather than against the last value alone.
Lets future operators see patterns instead of isolated records — which dimensions are stable, which drift, and which have already caused a fit failure.
Keeps the full history under the wearer's control, so moving to a new atelier moves the record with them rather than starting a new one.
