The production D60 branch added one sign to 1-based even signs, with no
source, while the repository's own guide and the vedastro mapping count
from the sign itself. PyJHora agrees with the latter: 33/77 recorded times
before, 77/77 after.
- scripts/varga.py: D60 is (si+pi)%12 for odd and even signs; other
mappings and the vedastro mode are untouched.
- tests/test_d60_varga_mapping.py: 12 signs x 60 parts against
PyJHora, plus the even-sign first part.
- scripts/research/d60_two_way_run.py: the G1 reconciliation that found
this, now in the repository with a test; G1 passes 77/77.
- scripts/varga.py is part of the extended frozen identity, so the sealed
holdout and the reported-offset sweep were re-frozen per ERR-110. All
20 and 900 trials match the upstream_sync9b records on every field and
the metrics and summary are unchanged.
