Light in the underground city: between food and daily life

The question to decide
In an underground city where farming facilities and residential space share the same light wells, some residents get almost no sunlight because of work hours. Rotational scheduling unsettles production cycles and community activities, and adding shafts means cutting other infrastructure budgets. How should light for food production and for residents' daily life be allocated and secured?

The options
The order shown is not a ranking of preference.
The situation as it stands
The underground residential zones have access to natural daylight only in some shared spaces. Decision deadline: five months until the maintenance plan for the daylight facilities.
A fictional underground residential city
- Premise 1The underground residential zones have access to natural daylight only in some shared spaces.
- Premise 2Agricultural facilities and resident spaces use the same light-access corridors.
- Premise 3Residents who work in other time slots get almost no sunlight under the current schedule.
Where it holdsSets the shared daylight facilities and the hours of space use. It cannot compel personal life cycles or the external climate.
What is still unknown
- Unknown 1Difference in lived experience between artificial lighting and natural daylight
- Unknown 2Maintenance cost and structural soundness of the new corridor
Signals to decide again
- Decide what observation, owner, and confirmation window can verify the "difference in lived experience between artificial lighting and natural daylight," and re-judge if a new finding changes the trade-offs of the options.
- Decide what observation, owner, and confirmation window can verify the "maintenance cost and structural soundness of the new corridor," and re-judge if a new finding changes the trade-offs of the options.
Where the paths partNot answers — paths that part from the same starting point
One of the existing corridors is closed for an extended period, reducing the slack available for allocation.
The farming team proposes a cultivation method that lowers some crops' dependence on daylight.
