Parallel-collision patterns — Prolog-derived diagrams

Facts: canonical_schema.CANONICAL_MERGE_KEYS (imported live), the verified C2 sweep (plans/briefs/kimi-c2-result.md), and the 2026-07-22 SHOW CONSTRAINTS census. Relations derived by SWI-Prolog (janus): mismatch/4, stale_live/4, port_collision_candidate/3. Generator: session scratchpad pattern_diagrams.py.

Pattern 1 — MERGE-key ≠ canonical constraint key

Pattern 2 — stale live constraints vs canonical schema

Pattern 3 — fixed-port bind sites across parallel batches
