Step 6 evaluated: infinity (never completes) to 24.1s measured
snackbar-to-snackbar, with the measured after-bar charted in step 6 (the
step-1 chart stays potential-only, per the format). Documents the second
localization loop the verification runs forced on the push half: UI death
by shared heap fate, odb cache exonerated, telemetry axis bug, mmaps named
as the eater, the impossible fixed-maps budget, the keep-alive race, and
pack layout as a device-performance variable.
The tradeoff-curves doc stays the chronological data layer; the kaizen
is the story layer — value model, 8-factor hypothesis table, ideas
ranked by verified cause, and an evaluation left PENDING until the
end-to-end on-device :sync lands.
