fix(plans)+test: #500 review — OCR rides Full not Compressed; OCR-RT gate is exact

Two review threads on the merged #500:
- codex P2: "post-POC OCR rides Compressed" was wrong — Compressed lacks
  Energy+Plasticity, so the schema-gated transcode would silently drop confidence
  (→Energy) and repair-provenance (→Plasticity). Corrected: OCR rides Full (the only
  preset with the codec residues AND the hot lifecycle columns). The OCR-SCHEMA
  contract test now asserts Compressed lacks Energy/Plasticity (regression guard).
- CodeRabbit Major: OCR-RT reversibility gate tightened 99% → 100% exact (a lossy
  residue→rank map is NOT "reversible"; tolerance moved to a separate quality probe).
