… drop stale 50+50 caveat Tested worklog avenue #1 (symbolic dependency mitigation) via a SymPy parse->transform->emit pre-pass, every variant lambdify-verified equivalent before solving. Result: 0 UNSAT across the exists_forall/ set for every provably-equivalent form (sig2tanh/expand/factor/horner/simplify); the graded ICP metric is invariant (~0.50 prune-empty & interval>=prec per loop-head for all forms) -> the poly*tanh(poly) coupling is untouched by syntactic form. sig2tanh is exactly verdict-neutral. The apparent factor/simplify speedup is an N1-delta-sat artifact: factor net-reduces the solved count (16x N2 blowup), simplify is uncomputable on N2 (>45s hang). Avenue #1 dead for this coupling; COMPLETENESS throughout (no form could produce a false unsat). - exists_forall_perf.md: new dated subsection with the full record - benchmark/SWEEP_odeexpr_v2.md: pointer + remove the now-satisfied 50+50 to-do (both referenced docs are already 25+25-accurate) - CLAUDE.md: terse "don't re-try symbolic rewrite" pointer on the worklog index Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
