…Gracker#34, Gracker#51, Gracker#70, Gracker#109, Gracker#112) MemoryRootCauseContract folds eight memory-class Spark ideas into one graph contract. Five facets, all optional and provenance-tagged so missing data surfaces explicitly: - ProcessMemorySnapshot[] for RSS / Swap / mm_event / oomScoreAdj (Spark Gracker#11) - LmkKillEvent[] tying kills to oom_score_adj and reason (Spark Gracker#12) - DmaBufAllocation[] for DMA / dmabuf / ion / GPU pressure (Spark Gracker#13) - MemoryExternalArtifact[] for LeakCanary / KOOM / hprof / baseline imports (Spark Gracker#51, Gracker#70, Gracker#109, Gracker#112) - baselineDiff with topContributors[] for the leak baseline diff graph (Spark Gracker#34) Plan: docs/superpowers/spark/plans/14-memory-lmk-dmabuf.md Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…racker#34, Gracker#51, Gracker#70, Gracker#109, Gracker#112) buildMemoryRootCause folds five orthogonal facets (process snapshots, LMK events, DMA/DMABUF allocations, external artifacts, baseline diff) into one MemoryRootCauseContract. baseline.perCategoryBytes is reduced to topContributors[] sorted by absolute delta so the largest-impact category surfaces first regardless of sign (Spark Gracker#34 leak baseline diff graph). Coverage status is computed per facet: LeakCanary external artifacts flip Spark Gracker#51/Gracker#70/Gracker#109 to implemented; KOOM artifacts flip Spark Gracker#112; baselineDiff flips Spark Gracker#34. Missing facets remain scaffolded so the contract honestly records partial coverage. When every facet is omitted, the contract is marked unsupportedReason rather than emitting an empty graph that consumers might mistake for "no memory pressure observed". Tests: 4 cases covering facet pass-through, topContributors ordering, LeakCanary status promotion, and unsupported.
