Kjell Tore Guttormsen 9d1f4b14ed test(fixtures): replace sector-specific example material with generic, fictitious examples — green
Every fixture, test document, tool example and document now uses an invented
kitchen-and-baking handbook series, written in this repository. The package's
behaviour is unchanged; src/ changes are comments and help text only.

- Generated fixtures are regenerated from their generators. Their structural
  counts are identical before and after: elements, images, rows, cells,
  headings, bookmarks and the witness inventory's per-document totals. The
  image-inbox and accounting documents are renamed kapittel-84-*.
- tools/okf_accounting_gate.py: the two options that named one real corpus
  each are replaced by a generic, repeatable --corpus PATH with no default.
  Row 5 compares the PDF pair alone. Gate verdict unchanged: RED rows 2, 3, 6.
- tools/okf_witness.py: the STS JSON reader for one publisher's delivery is
  removed, along with its three twins and five tests. The mutation harness
  loses W09.
- docs/: 13 dated reports that documented runs on a retired reference corpus
  are removed, and 40 are neutralized. Dead links are removed, and no new
  dangling path is introduced.
- The synthetic MCP-gate corpus and the residual probe words are neutral.

Valgt: keep the `okf quality --fasit` bar value (the measured fraction, one corpus) and
rewrite only its provenance, because the verdict stays unchanged and the
number names nothing.

Term check with the local list: 0 of 411 tracked files, 0 file names, 0 of
27 binary fixtures. Suite after git add: 2457 passed, 1 skipped. The base
tree had 2460 passed and 2 skipped; five tests went with the JSON reader and
four were added by the term check. ruff, ruff format and mypy --strict src/
are clean.

"""The content-accounting gate's own tests (`tools/okf_accounting_gate.py`).
The gate was written RED at `0b00de4`, before `okf build` had a source
inventory or a per-element account. These tests are GREEN and prove three things.
1. The fasit is independent. `tools/okf_witness.py` imports no
`llm_ingestion_okf` module -- checked on the live import graph of a process
that ran every witness, with a control that shows the check fires -- and
the committed inventories are exactly what the witness counts today, pinned
again to hand counts on four documents.
2. Every row CAN turn green and CAN turn red, each boundary driven from both
sides with synthetic build output (the door the capability must open).
3. Run against the real `okf build`, the fixture rows are green. They were
red at `0b00de4` on the three defects the gate was ordered for (no
inventory, a file carried AND rejected, a rejected document logged as "0
carried of 0 found"); `test_a_file_carried_through_a_document_and_rejected_
is_double_booked` and the row 4 tests keep those defects detectable.
