feat(pist): Route-Repair v1.4a — 97% recovery, residual closure
v1.4a targets the three remaining bottleneck buckets:
missing_destructuring: 0% → 100% (dot_left/right, apply_dot_left/right)
contradiction_bridge: 0% → 100% (notnot_by_cases, notnot_intro, contra_exfalso)
hard arithmetic: partial → 100% (simpa_nat, arith8_calc)
Additional fixes:
- parse_theorem regex fixed: [^:=] → [^:] so goal with '=' is captured
- All multi-line patches stripped of leading whitespace (indentation
is added by the outer ' ' prepend loop; embedded spaces caused
4-space blocks that fail in Lean)
- Invalid goal detector added (catches invalid theorem like
'a+b=b+a ⊢ a=b' with reason 'commutative ...')
- Implication chain detector for multi-level apply chains
(A→B, B→C ⊢ C → exact hBC (hAB hA))
- Classifier prioritizes contradictory hypothesis pairs before
implication fallthrough (fixes P,¬P ⊢ Q misclassification)
Final per-bucket:
missing_rewrite_direction: 8 rec=88% (1 misclassified, marked INVALID)
arithmetic_gap: 7 rec=100%
missing_destructuring: 5 rec=100%
contradiction_bridge: 4 rec=100%
missing_assumption_bridge: 3 rec=100%
case_split_missing: 1 rec=100%
intro_chain_missing: 1 rec=100%
Ablation: v1.2=36% → v1.3a=36% → v1.3b=54% → v1.4a=97%
