Read this query back to me.

Query:
PASTE IT
What the result is supposed to mean: WHAT.

Six parts.

One sentence. What this query returns.

The grain. One row of the output is one what. State it exactly, because
most argued numbers are a grain disagreement.

Tables and joins. For each join: which one it is, on what, and what it
does to the row count. Name any join that can multiply rows, and any
outer join whose filter in the WHERE clause silently turns it into an
inner one.

Filters. Every condition, in plain words, including the ones hidden in
a join condition. Flag any comparison against a column that can be
null, because null comparisons drop rows without saying so.

Counts and sums. For each one: what exactly is being counted, whether
duplicates are included, and whether the denominator of any ratio is
the same population as its numerator.

Traps, ranked. The ways this query could return a number that looks
right and is not. Date boundaries that include or exclude a day, a
timezone, a deleted or inactive flag not filtered, a currency or unit
mix, a grouping that hides a duplicate.

Then: the smallest check that would confirm the result. Usually a count
at a different grain, or the same query over a period whose answer I
already know.

You cannot run this, so mark anything that depends on the data rather
than the query text as something to verify.
