Drew T ba6cb87d30 feat(phase-20): T2 — exemplar_miner routes 835 residuals (WAVE 472 / PINS 45 reach-134 / STUB 90) 
- tools/exemplar_miner.py: consume wall_taxonomy.json + per-overlay reach (dedup_propagate's
  computation) -> route each residual to a lever (WAVE/STRUCT/PINS/STUB); emit
  docs/exemplar_curriculum.md + .run/exemplar_routing.json (wave-gen input)
- routing: WAVE 472 (218 reach-134, T6 fuel) / STRUCT 159 / PINS 114 (45 reach-134) / STUB 90
  (74 ARITY_WALL loose-typing + 16 NONFAITHFUL, honest P9)
- KEY T3 input: 17 reach-134 fns at m2c-mismatch=1 = cleanest regalloc/schedule isolates
  (likely SS17-pins wins + the genuine class residuals); 3 named exemplars confirmed reach-134
- note: census is the Jun-19 snapshot (pre-Phase-19 waves); T5/T6 regen = authoritative WAVE list

# BFM residual curriculum / router (generated by tools/exemplar_miner.py)
# census: .run/wall_taxonomy.json (snapshot 2026-06-19, 835 unregistered residual stubs in ov_SC01_077)
# reach = #overlays sharing the byte-identical copy (×N propagation leverage), computed from sigs.
# ROUTING IS ADVISORY — the per-overlay byte-gate is the sole arbiter (G3/P9). `mismatch` is the
# M2C-DRAFT mismatch (scaffold quality), NOT the hand-match floor.
## Routing summary (by lever, reach-weighted)
| lever | fns | reach-134 | Σ reach | what it is |
|---|---|---|---|---|
| WAVE | 472 | 218 | 29468 | Ultracode swarm + §17 toolkit + canon-first gate (the yield engine, T6) |
| STRUCT | 159 | 12 | 1755 | m2c blocked on a type (fn-ptr/jump tables, struct deref) — needs type context |
| PINS | 114 | 45 | 6099 | regalloc/schedule near-miss — register-pin hand-match; class-crack pool (T3) |
| STUB | 90 | 58 | 7804 | fundamental loose-typing (ARITY_WALL) / non-faithful — honest INCLUDE_ASM (P9) |
