It could never score. The schema records VO2max but cannot tell a
measured test apart from a device estimate, so every fitness row reached
the scorer unproven and was refused - the pillar has never produced a
value on any account. Listing it on the score settings page as a thing
you can choose, with a line admitting it does nothing, was chrome over a
switch that changed no number.
So it leaves the catalogue: no pillar id, no domain, no scorer, no row,
no wire field. A stored selection that still names it reads back fine -
the resolver has always filtered stored ids against the catalogue and
drops what it no longer knows, so nobody's saved recipe throws or is
discarded over it.
That also fixes the page claiming unsaved changes forever. The save
stripped the fitness pillar out of the selection on its way to the
server, so the answer that came back could never match the form that
sent it, and 'All pillars' left the save button lit no matter how often
you pressed it.
Until now the set of pillars behind the Health Score was assembled from
the module switches alone, in a stack of ternaries inside the reader. A
person who turned the sleep module off lost the sleep pillar from their
number as a side effect of a setting about recording data, and there was
nowhere else to say what should count.
The reader now reads the stored recipe and narrows it to the pillars a
module is actually recording. The mapping from module to pillar moves
out of the ternaries into a named map beside the reader, where it can be
read and tested. Glycaemia stays fed by either glucose or labs, which
was the one entry a one-module-per-pillar map would have lost.
Nobody's number moves on upgrade. An account that never opened the new
surface resolves to every pillar, and every pillar narrowed by module
availability is exactly the set the ternaries built, so the inheritance
holds by construction with no backfill.
A pillar the recipe selects whose module is off produces no row at all,
rather than a "waiting for data" line. Turning a module off is a
deliberate act, and asking someone for data they chose to stop recording
would be nagging them in the voice of their own settings.
