Commit executed outputs for the geography query notebook #133

Follow-up to #131, which adds the geography query suite.

notebooks/queries.ipynb ships with executed outputs — every query cell has a result table, and those tables are what appear in docs/queries.md. notebooks/geography-queries.ipynb was committed without outputs, because executing it today would put misleading results into the docs.

Why it was deferred

Two SedonaDB defects, both filed and both engine-side:

• apache/sedona-db#1084 — a geography scalar function over the output of a geography spatial join fails with Array input must not be empty. Q9 raises this, so its cell would carry an error traceback.
• apache/sedona-db#1085 — one zone polygon of 156 095 (z_zonekey 150480) returns a negative geography ST_Area and matches points anywhere on Earth. Q4, Q6, Q10 and Q11 are all distorted by it: at SF1, Q6 would display Shendi | 5999980 — essentially every trip in the dataset, for a county nowhere near the query area — and Q11 would report 6 290 682 cross-zone trips against the planar suite's 176 391.

Committing those outputs would document engine bugs as if they were the queries' results, and the page deliberately carries no engine-defect discussion.

Executing only the sound subset was considered and rejected: a notebook where some cells have outputs and others do not reads as broken rather than deliberate.

What to do

Once #1084 and #1085 are released:

1. Install the docs environment (docs/requirements.txt, which brings apache-sedona[db]) and generate or download SF1 data.
2. Run notebooks/geography-queries.ipynb top to bottom. Q12 is a markdown cell, not a code cell, so it will not error — it needs a geography ST_KNN (apache/sedona-db#1086, Add Geography support for ST_KNN sedona#3178).
3. Regenerate the page: python -m nbconvert --to markdown notebooks/geography-queries.ipynb, then re-prepend the YAML front matter and ASF license header that docs/geography-queries.md carries (the notebook itself is RAT-excluded via *.ipynb; the page is not, unlike docs/queries.md).
4. Run pre-commit run --files ... — the end-of-file fixer adjusts nbconvert's trailing newlines.
5. Mirror the new output blocks into docs/geography-queries.zh.md, which is maintained by hand from the English page.

Sanity checks worth keeping

At SF1 the geography results were verified against the committed geometry answers: Q2 matches exactly (541), Q3 matches its row count (22), Q4 reproduces the geometry answer row for row (258 zones, same counts, same order) once the #1085 polygon is excluded, and Q9's self-join finds the same 37 building pairs. Those are good regression anchors when the outputs are finally committed.
