Three independent root causes behind the divergences the reporter
flagged after the archived-spool fix shipped — fixed together.
(1) Filament Used vs Total Consumed.
_compute_run_filament_grams returned the slicer estimate for completed
prints even when inventory had measured the actual AMS weight delta.
That made Stats and Inventory two different sources of truth: Stats
showed slicer-estimate grams, Inventory showed AMS-tracked grams, and
the two never agreed. Reordered the helper so the tracked spool delta
(same source that drives weight_used behind Total Consumed) takes
priority for every status. Slicer estimate stays as the fallback when
no inventory was tracked; partial-progress scale stays as the fallback
for failed/cancelled with no tracker. The _run_cost block right next
to it was already tracker-first; only filament_used_grams was
inconsistent.
(2) Printer Stats By Time vs Quick Stats Print Time.
/archives/slim only set actual_time_seconds when status == "completed".
For failed/cancelled rows the frontend fell back to print_time_seconds
(the slicer's full-print estimate — wrong number for a print that
failed at 15%). Quick Stats already summed elapsed duration across
all statuses, so the two halves of the page disagreed by the
(estimate - actual-elapsed) gap on every non-completed event. Dropped
the completed-only gate; failed/cancelled now report measured elapsed.
(3) Success Rate %.
Was successful / (successful + failed), excluding cancelled / stopped
from the denominator. With "Total Prints: N" displayed right above
the gauge that produced confusing numbers — 4 successful, 0 failed,
48 cancelled showed 100% out of an apparent 52 prints. Switched to
successful / total_prints — matches the count the user reads from
the widget header.
