SIX-CALIB: does a near miss on a quintuple predict that the quintuple extends to a sextuple?
Data: Paper 9 supplement (results/quint_census.tsv.xz, results/sextuples77.txt); quint6.jsonl = sieve rows with near elements
listed (my census, Oct 21). Run (Python 3, stdlib only):  xz -dk results/quint_census.tsv.xz; python3 lift.py; python3 checks.py
lift.py   slack-1 rows (runs q301_1000, q1000_2000). Automatic near miss = regular fifth of tau+{d}, d outside the sieved triple
          tau (pays tau's 3 conditions and d's by construction); non-automatic = stored near count minus automatic ones.
          Prints lift = P(sixth | non-automatic near) / P(sixth), Fisher one-sided p, rank strata.
checks.py (1) on quint6.jsonl every automatic near miss appears among the listed near elements; (2) data integrity: the
          sub-quintuples of the 77 sextuples present in the table list their sixth element; (3) Mantel-Haenszel OR, exact CI.
lift.out, checks.out: outputs.
