Two defects the first whole-repository scan made visible. It ran for 23
minutes over Paid Memberships Pro and decided nothing.
**The batch was 97.5% duplication.** `hookCallbacks` describes the REPOSITORY,
not the region, and I put it in every request when the hook half landed. On a
637-file plugin that is 16,270 characters repeated across 2,500 requests:
taint-requests.json 42.5 MB, of which 41.7 MB is one string over again
Joern parsed that with ujson inside a 2GB heap and the batch died in
ForkJoinPool. The driver reported `query_failed` for all 2,500 regions, which
was the honest answer to a question that never should have been asked that
way. Repository-wide fields are now hoisted to a single `--param`, and only if
they are identical across the whole batch -- a field that genuinely varies per
region stays where it belongs.
**Arbitration spent 737 seconds enumerating candidates nobody would read.**
Candidates exist to be put to the judge, and `scan_region` discards them the
moment there is no judge to put them to -- but the driver enumerated them
first regardless, parsing each region's file once per family. With the budget
at zero model calls that is 2,500 parses whose results are dropped on arrival.

Nobody should pay for a question nobody will ask.
848 tests pass; gates byte-identical.
