Per-domain status.md grids + ledger show --matrix [--domain X]

Goal

Render ONE grid per domain into the human read surface (status.md) and a ledger show --matrix [--domain X] CLI, both consuming read_matrix (no per-surface re-derivation).

Implementation Sketch

render.py emits one labeled grid PER DOMAIN (rows=shape, cols=mechanism_class, cell=folded state + facet) into status.md; python -m scripts.plan_corpus.ledger show <plan> --matrix [--domain X] renders all domain grids (or one) + each domain’s ranked frontier. Both call read_matrix (a surface computing its own projection is a LEAK:algorithmic-duplication).

Spec References

Design v6 D6 + D7. learning-ledger.md §13.2 (single read API; no per-surface ranking).

Work Items

  • render.py writes one matrix grid per domain into status.md via read_matrix.
  • ledger show --matrix [--domain X] CLI renders per-domain grids + each domain’s ranked frontier.
  • Both surfaces consume read_matrix; no duplicated projection logic.
