G.9:3 — Forces

• Pluralism vs comparability. Multiple Traditions must be comparable without semantic collapse.
• Partial orders. Many targets are only partially ordered; parity reporting must preserve CSLC-admissible outcome shape (often selected sets or archives rather than a single scalar).
• Edition sensitivity. Parity must be robust to silent drift in measurement and comparator definitions. When DHC, QD, or OEE modes are used, the required definition pins are introduced only through the corresponding Extensions blocks; omit them when unused.
• Telemetry versus objectives. IlluminationSummary, coverage, and regret are report-only telemetry by default. A dominance change needs an explicit CAL policy id recorded in the audit pins.
• Crossing visibility. Every crossing used by parity must be visible and auditable through its CrossingBundle and GateCrossing checks; failure blocks publication or use of the parity result.
• Cross-sense and reference-plane reuse. When expressions have distinct F.17 source-local meanings, recover both cells and establish the required F.9 relation; a ReferencePlane crossing follows its own declared crossing basis. Each actual crossing carries explicit pins, its audit evidence relation, and R-channel penalty placement.
• Refreshability. Parity must emit RSCR‑relevant causes as canonical ids, with enough pins to re‑run.
