The table under the roof for Dinner outside. October 30, 2026 at 4:00 AM, America/New_York. Now on this date. Confidence low. Cause: What it feels like is what stops it.

Sit down, eat, and still want to be there ninety minutes later.

Dinner outside

We cannot say yet whether The table under the roof works for dinner outside, because privacy exposure is still unanswered.

“Unanswered” means missing evidence prevents a reliable verdict. The questions that need answering are listed below.

  • Past the limit What it feels like is about 51°F — 8°F under (at least 59°F)Estimate: Worked out, but at least one input was assumed rather than measured.

    The air is 62.2°F. It feels about 11.2 degrees cooler than the air, near 51°F.

    Nobody finishes a meal in a seat that is cooking.

Still unanswered:Privacy exposureViewNoise
Why these are unanswered
  • Privacy exposure. No observer has been placed yet. Privacy is a question about who can see in from where, and until one is marked there is nothing to answer.
  • View. No view worth keeping has been marked, so there is nothing to weigh a screen against yet.
  • Noise. Nobody has told us what the noise is like here, and it is not something geometry can infer.

What would change this. This stays unanswered until privacy exposure is known. No observer has been placed yet. Privacy is a question about who can see in from where, and until one is marked there is nothing to answer.

Confidence low (30%). Treat this as a starting hypothesis, not an answer.

What next here

Testing a change

3 of 8 milestones. One thing is still in the way of privacy, sightlines and screening advice.

  1. Getting an honest answer3 of 4 done
    • Placed on the earth — done. The sun is in the right part of the sky for this address.
    • A spot to read — done. 1 spot is being read.
    • What stands in the way — done. 4 things are drawn, so the shade is worked out rather than assumed.
    • Who can see in — not done. Privacy is the most common reason a terrace goes unused, and it cannot be answered without knowing which windows look at it.
  2. Testing a changeyou are here0 of 2 done
    • A change tested — not done. Testing a change before buying it is the cheapest part of the whole exercise.
    • A forecast checked — not done. A forecast nobody goes back and checks is a guess with a date on it.
  3. Proving it well enough to spend money0 of 2 done
    • Corrected against reality — not done. After a couple of rechecks the model can be corrected against this specific garden.
    • Photographed — not done. A photograph is what turns a drawing somebody sketched into a drawing somebody can check.
  1. Mark the windows that look at this spot

    Being overlooked is one of the most common reasons a good terrace goes unused, and it is the one reading here that cannot be inferred from anything else.

    a tap per windowneeded for privacy, sightlines and screening advice
  2. Get this place to Annotated

    A photographic check on the mapped sightlines and geometry. That makes privacy estimates more credible, but does not replace measured dimensions. Right now: Sightlines drawn from mapped observers remain provisional until their positions and heights are checked. The drawn heights have not been verified against the actual place. What is missing: Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one. Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement. Who can see in: Nobody marked. Privacy is a question about who sees in from where, and the product will not invent one.

    3 things left
  3. Test a change before you buy anything

    The plan is good enough to ask what a screen, a tree or a canopy would actually do here — including the ones that turn out to be a waste of money.

    a few minutes, nothing bought
3 more things worth doing here
  1. Add a second spot and compare the two

    One spot gives a verdict; two give a reason. Most of what is worth learning here is why one corner works at six and the other never does.

    one tap, then read across
  2. See how this spot changes through the year

    A terrace that works in July can be unusable in September for reasons that have nothing to do with temperature. The same geometry read in four seasons is the cheapest insight here.

    a read, nothing to enter
  3. Photograph the spot and mark what is in shot

    A photograph is what separates a drawing you sketched from a drawing somebody else can check. It is also how heights get corrected without a ladder.

Mapped
  1. Quick
  2. Mapped
  3. Annotated
  4. Measured

Shade, sky view and daily light are computed from the geometry on this plan. Unmeasured dimensions remain estimates, not verified measurements.

Sightlines drawn from mapped observers remain provisional until their positions and heights are checked. The drawn heights have not been verified against the actual place.

To reach Annotated

  • Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one.
  • Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement.
  • Who can see in: Nobody marked. Privacy is a question about who sees in from where, and the product will not invent one.

What that buys: A photographic check on the mapped sightlines and geometry. That makes privacy estimates more credible, but does not replace measured dimensions.

Everything that was checked
  • Quick A place on the earth: Atlanta (demonstration), with a time zone, which is what makes an hour an hour.
  • Quick Somewhere to read: 1 spot marked. A reading is a height at a place, and moving it moves the answer.
  • Mapped The things in the way: 4 objects drawn. The house counts, and so does the neighbour's.
  • Mapped What is underfoot: 1 of 1 readings sit on a mapped surface.
  • Mapped Where the property ends: Drawn, so the product can tell you when the cheapest fix stands on someone else's land.
  • Annotated Photographs of the actual place: None annotated. A photograph is how a drawn height gets checked against a real one.
  • Annotated Photographs that know where they were taken from: No photograph has a position and a bearing, so what is marked on them cannot become a measurement.
  • Annotated Who can see in: Nobody marked. Privacy is a question about who sees in from where, and the product will not invent one.
  • Measured Heights off a tape: 1 of 4 objects are measured. The remaining 3 are this product's own inference, so no figure here is a survey figure yet.
  • Measured Something checked against the day: Nothing has been checked against a real afternoon. The model is unopposed, which is not the same as being right.

What to measure next

Ranked by how far the answer moves, not by a checklist
  1. 1Who can actually see inSit in the chair

    Sit where you actually sit and look around. Mark the one window or path you can see a person from. Until one exists, privacy is a question we are not answering rather than one that is fine.

    This is not a refinement. Nothing can answer this question until somebody marks it.

    Currently assuming: nobody is overlooking this. Tested across one confirmed observer changes the whole privacy answer.

  2. 2What you are looking atSit in the chair

    Mark the direction of the view worth keeping. No view has been marked yet, so nothing weighs what the view is worth, and a screen that blocks it looks free.

    This is not a refinement. Nothing can answer this question until somebody marks it.

    Currently assuming: no view is being protected. Tested across one corridor changes what screening is worth doing.

The sun is down.

October 30 · The table under the roof Schematic: A shape of the facts, not a picture of a particular date or a measured outline.
  • Unanswered (hatched)

The sun reaches the table under the roof at 7:56 AM. The table under the roof loses the sun at 9:39 AM because of the Carport roof.

The evidence behind this whole day is thin, so nothing on the strip is marked out as worse than the rest. The shape of the day is still the model’s best reading; the confidence in it is low, and it stays low until something it needs is measured.

The table under the roof cannot be answered for dinner outside yet.

Nothing in October clears what dinner outside needs here.
