chore(rectification): re-freeze research records for upstream sync 4 (ERR-110); scores unchanged, no version bump

scripts/shadbala.py is in the frozen scoring identity (dataset
frozen_scoring.files), so the ported Kala/Chesta fixes and the BPHS Sun
minimum (BUG-1188/1189) turned the integrity gate red although the scorer only
reads the Sthana/Drik/Naisargika components. Records re-frozen under the label
upstream_sync4_2026_10_02 (--freeze, then replay; PYTHONHASHSEED=0, chart cache
TTL 0); the functional_v2 records become "previous", byte-for-byte preserved.
Replays are identical to functional_v2: reported offset 0 of 900 trials
changed, sealed holdout 20 trials identical; memoization golden v2 scores
unchanged and the v5 77-case evaluation is byte-identical to a18f8d4e, so
ALGORITHM_VERSION stays rectification-v5-matrix-scoring-10 (decision 6 only
bumps on a score change).
