======================================================================

[1] MODEL VERIFICATION
  Model-related fields in fast: {'model_answer'}
  Model-related fields in full: {'model_answer'}
  Source scripts hard-code MODEL='cerebras/llama3.1-8b' (run_fast.py L26, run_full.py L33)
  Scripts contain assert MODEL in _FREE_MODELS; no mixing possible without code change
  VERDICT: PASS — files cannot mix models (model is constant per-script, not per-record)

[2] PER-TYPE VS AGGREGATE FRAGILITY CONSISTENCY (full only)
  Violations (per-type max > fragility_max OR frag outside [min,max]): 0

  Records where |diff| > 0.05: 0

======================================================================
KEY ANOMALY — perturbation type coverage in full_817:
  Only 1 of 31 records used all 13 perturbation types.
  - 'semantic' perturbation MISSING in 30/31 records
  - 'synonym'  perturbation MISSING in 16/31 records
  All 13 types appear somewhere; likely per-variant API/parse failures
  silently reduced n_perturbations (36/33/32/35 distribution).
  Impact: per_type_fragility incomplete for 'semantic' in 97% of full rows.

ISSUES FOUND:
  - Perturbation coverage: full_817 missing 'semantic'/'synonym' for most rows
  - verbalized_confidence fallback (=0.5): fast 23/379 (6.1%), full 2/31 (6.5%)
  - verbalized_confidence ==0.0 in fast: 11/379 (edge case, not NaN)
  - scan_duration 6 outliers >5×median (likely API retry, not timeout — max 80s under 60s timeout×retry budget)

VERDICT: PASS (with caveats)
  All range/NaN/truncation/mixing checks PASS.
  Only concern: full_817 perturbation coverage is incomplete (only 1/31
  records got all 13 types). Use with care for per-type 'semantic' stats.
