Drew T de35505a63 feat(phase-19): scale the toolkit — 2 waves (88%/92%), fleet 56.64%->58.00%, propagation is the cap (v1.18.0)
- T1 (prior session, commit:0158/commit:0159): per-file -O0 split infra + 6 -O0 matches; deferred the
  10 %lo-folding-quirk fns + the ×134 rollout (R14 corrected "free ×134")
- T2 (commit:0161): recovery tooling. R14: the 3 Phase-18 "implicit-int" near-misses are NOT
  implicit-int -> resident-callee link-miss (NEW canon_resident_calls.py) + shared-caller arity
  (no-proto caller-extern fix). 3 matches; cookbook §17a-3 corrected
- T3 (commit:0162/commit:0163/commit:0164): 2 Ultracode waves over reach-134 tractable residuals. batch-1
  44/50 match_one (30 banked, 25 propagated ×134); batch-2 35/38 (25 banked, 10 propagated).
  NEW fix_arity_callers.py (no-proto, ALL 18 batch-2 failures were the arity class); canon-first
  2-stage gate (sig_unify REGRESSES canonical drafts); gen_harvest_targets garbled-sig fix
  (0/749, 88%->92%); build_engine_types --strip lift (+4 propagated)
- FINDING: propagation (not matching) caps the fleet-% yield — typedef/local-type bodies can't
  auto-propagate (-> Phase-20 type-lift lever). decomp.dev-comparable byte-weighted est ~30%
- check-all 136/136 BYTE-IDENTICAL (R22); dedup 1450->1485/0 failed; 0 NON_MATCHING (G4);
  fleet 56.64% -> 58.00% (+1.36%). worklog -> phase-ends/logs/Phase19.md (R19)
- bumps 1.17.0 -> 1.18.0
