chore(infra): stage pist canary labeling and training shims + flexure report
- label_canary_theorems.py: infer ground-truth multi-labels from Lean receipts (proof_method, domain, RRCShape) via pattern matching — pure I/O - pist_enrich_and_train.py: run pist-decompose → extract features → train centroid/KNN classifiers — float only at external boundary (acceptable) - pist_train_ground_truth.py: LOOCV evaluation on ground-truth labels — statistical training, no decision logic - shared-data/pist_flexure_library_report.json: updated flexure library report All three shims: pure I/O, no admissibility/gating decisions, float only in normalization (external boundary). Complies with AGENTS.md §Programming Choice Flow. Outputs are regenerable from source receipts. Build: Compiler 3311 jobs, 0 errors (no Lean changes). Generated with Devin (https://cli.devin.ai/docs) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
