The context sets, the packaged knowledge bases and the example bundles are
replaced by one fictitious example set about IT operations in an invented
organisation: three context sets (serverrom-2027, driftsavtale-2027 and the
two-base drift-og-avtale-2027), two synthetic knowledge bases under
src/portfolio_optimiser/data/kunnskapsbaser and two example bundles under
src/portfolio_optimiser/data/bundles. Numbers, codes and structural values in
tests and fixtures are kept; names, ids and wording change. Dated measurement
documents that only recorded runs on the replaced material are deleted.
Gate figures measured on the new set are not comparable with earlier ones.
The exclusion gate from the previous commit is green: 0 tracked files hit
outside the shared/ subtree.

Two quantization orders existed and met at exactly one comparison.
SavingsLedger quantizes every realized candidate to integer øre and sums the
ints; run.py's goal baselines summed Project.total_cost FLOATS across items and
projects and quantized the total once. _goal_limit_if_reached compared the
former against a threshold derived from the latter — so whether a portfolio pass
stops early was decided by two differently-computed sides.
Measured divergence: three 60000.005 NOK lines are 18000003 øre quantized first
but 18000001 summed first (the float sum drifts to 180000.01499999998).
Decision: quantize per cost line, then sum integers. Each CostItem IS a money
amount — S4.0 made per-line quantity/unit_cost the validator's ground truth — and
integer addition is associative, keeping totals order-independent under the D-D
wave model, which the float fold is not.
ledger.to_ore is now the framework's one NOK->øre conversion; run.py imports it
rather than keeping a private copy (the S4.0 REPLIES precedent).
Measuring the mutations found two further gaps, both now closed: the per-project
baseline is a SECOND call site whose mutation survived the whole suite, and
realize bypassing to_ore with a raw float*100 was caught by nothing.
Load-bearing MEASURED (tests/test_money_quantization_loadbearing.py), five
mutations all red: detach the portfolio baseline · detach the per-project
baseline · reintroduce a private copy in run.py · change the rounding mode · let
realize bypass to_ore. 615 -> 621 tests.
Honesty boundary: sum_claimed_saving_nok (run.py:_aggregate) is deliberately
untouched — a float NOK reporting field that is never quantized and never
compared against the ledger, hence outside the ordering defect.
