 ### Priority Actions
 
 1. **Merge functional decomposition concerns** (1.1) — trivial, clear win.
 2. **Merge functional scope concerns** (1.2) — same viewpoint, same intent.
 3. **Collapse the framework grid concerns** (1.3) — three into one.
-4. **Parameterize conceptual vs. physical** across all affected pairs — reduces concern count by ~8 while preserving semantic fidelity.
-5. **Collapse exchange item fragmentation** (2.6) — 7 concerns → 2.
-6. **Assign or deprecate orphaned concerns** — especially the 4 reliability concerns that have zero viewpoint coverage.
-7. **Fix categorization mismatches** — move 3 concerns to appropriate owners.
+4. **Investigate #1 vs #2 in exchange items** (2.6) — these are the only two occupying the same cell (conceptual + identification); everything else in that section is structurally justified.
+5. **Assign or deprecate orphaned concerns** — especially the 4 reliability concerns that have zero viewpoint coverage.
+6. **Fix categorization mismatches** — move 3 concerns to appropriate owners.
