Suggestions Decisions 5, 7, 9 — cross-axis pattern recognition with contextual qualifiers

Skeleton Phase 5 of the drafting plan — the suggestion engine rules from Decisions 5 / 6 / 9 will be wired here. Cross-axis rules (clearance-throughput mismatch, distributive shock ScvO₂ caveat, UF intolerance pattern) are specified in the design notes.

CRRT Constraint Model v1 — Phase 1 skeleton. Quadrilateral architecture per Decision 8 with vertex ordering (paired-by-coupling): volume balance (12 o'clock) opposite hemodynamics (6 o'clock); solute clearance (9 o'clock) opposite metabolic adequacy (3 o'clock). Trajectory cadence 6h per Decision 9. Architectural foundation in crrt-design-notes.md; visual lineage with ventilator-interpreter.html. Remaining drafting phases: data model wiring (Phase 2), trajectory rendering (Phase 3), panel computation (Phase 4), suggestion engine (Phase 5), ROSE phase overlay (Phase 6).
