The "Late" task view marks late any task still open inside its duty's grace_days — the view's definition of late disagrees with the product's #48

Noticed while implementing the analytics datasets (#9); filed rather than fixed because
src/views/ was outside that card's file surface.

Observation

src/views/task.view.ts, the late list view:

filter: [
  { field: 'due_date', operator: 'less_than', value: '{today}' },
  { field: 'status', operator: 'in', value: ['open', 'in_progress'] },
],

The product's definition of late (#9, and duly_duty.grace_days's own field description —
"Days after the due date before an open task counts as late") is:

due_date + grace_days is past, and the task is not done

The view drops the + grace_days. So a task whose duty grants 7 days of grace shows up in
"Late" the morning after its due date — six days before it is late. The view's own comment
explains why it reads stored columns rather than a flag, which is right; it just does not
mention that it is also dropping grace.

Consequence in use: grace is the mechanism that stops a monthly duty due on the 5th from
looking failed on the 6th, and the one screen a manager reads for lateness ignores it.
Every duty that sets a non-zero grace is mis-reported by exactly that many days.

This is the same root gap as the missing on-time measures

Not independently fixable today. A view filter is { field, operator, value } and there is
no operator that compares a column against another column plus an offset held in a third
column — the same limitation that removed tasks_done_on_time, tasks_late and the
on-time rate from duly_duty_health in #9. Filed upstream as
objectstack-ai/objectstack#14104.

So this is not "fix the view", it is "the app has two surfaces that both need the same
missing capability, and only one of them currently admits it". #9's dataset omits the
measure and says why; this view ships an approximation silently.

Suggested handling

Two options, both cheap, neither requiring the upstream fix:

1. Say so in the view. Rename to something honest (Past due) and/or add a comment
   recording that grace is not applied and why. Costs nothing and stops the next reader
   assuming the view is authoritative.
2. Leave the filter, fix the framing. Keep Late but treat #14104 as the blocker and
   link it from the view so the two surfaces tell the same story.

Flagging it as a product decision rather than picking one: whether "Late" should mean
"past due" or "past grace" on the operational screen is a call for the maintainer, and it
may legitimately differ from what the metric layer counts.
