Decision-engine task 6.7 (partial). After the advisory-fix harvest (memory 724 -> 904 static examples),
one compile per evaluable family and an outer grouped 5-fold evaluation of that family's own candidates,
input profile v1, priors off, k = 5, cross-fitted Platt, nested operating points (repository-cluster
bootstrap 95%):

  family                 n   AUC(s)              ADVISORY R / P   'vulnerable' P / R   ECE    canary
  injection            110   0.77 [0.67, 0.88]   0.88 / 0.57      0.84 / 0.36          0.093  0.77
  untrusted_dest.       62   0.85 [0.76, 0.94]   0.84 / 0.73      0.96 / 0.66          0.071  0.87
  path                  35   0.89 [0.79, 0.97]   0.86 / 0.69      0.89 / 0.76          0.119  0.90
  output_encoding       44   0.91 [0.82, 0.97]   0.86 / 0.81      0.94 / 0.55          0.045  0.90
  deserialization       46   0.90 [0.82, 0.97]   0.83 / 0.76      0.93 / 0.83          0.095  0.93
  access_control        37   0.96 [0.90, 1.00]   0.91 / 0.91      1.00 / 0.61          0.076  0.83

BLOCK offered for none: calibration fails everywhere except output_encoding, where no fold reaches a
Wilson lower bound of 0.95. Within paired groups (a function and its own fix) AUC is lower, 0.72-0.93:
every single-label group in the new families holds positives only. Injection learning-curve point,
paired (same program, candidates, folds): memory 724 -> 904, AUC 0.76 -> 0.77 (no injection example
was added). $2.88 metered DeepSeek (ceiling $8; balance 17.73 -> 16.73), $0.0009 embeddings.

Instrument fix: compiled demonstrations now follow the near-duplicate rule (cos >= 0.98) that retrieval
and the pre-call assertion apply; the assertion had stopped the untrusted_destination evaluation.
