Session brief (scope, non-goals, pinned SQL type/number decisions, verification) + TDD plan + build_fixture.py (regenerates the sqlite golden; the committed db bytes need not reproduce — the golden compares the derived bundle).

"""Build the I4 sql golden fixture: examples/ingest-golden-sql/fixture/portefolje.sqlite
|
|
+ ingested-at.txt.
|
|
|
|
Regenerable; the committed db BYTES need not be reproduced bit-for-bit — the golden test
|
|
compares the derived bundle (from db CONTENT via the manifest queries), not the db file.
|
|
Parameterized inserts keep the backslash/pipe escape-probe values exact (no SQL string-literal
|
|
surprises: 'c:\\temp' would be a tab if written as a Python literal). The data is chosen to
|
|
discriminate a typed §5 implementation from naive ones — SQL NULL, an integral REAL (4200.0),
|
|
non-integral REALs, and pipe/backslash text.
