Evaluation for the GOS + NitroSketch sampling work in this stack: - DEBS 2022 real-backend query-accuracy harness (all 4 sketch query types), Google cluster trace integrated ε-sweep (accuracy·latency·freshness·resources, single-node + cluster), C1 bandwidth/encoding-factor experiments (DDSketch/HLL vs raw+gzip), anisotropic-vs-isotropic per-cell delta measurement (historical — anisotropic itself was later removed from #517 pending an Activity_j redesign; this eval data predates that and is kept for the record), raw-vs-sketch cardinality crossover. - otel_collector_benchmark/epsilon_floor: ε-floor vs NitroSketch benchmark, in-tree. - docs/gos-eval-results.md, docs/phase-2.md: recorded eval results and phase-2 implementation history. docs/design-gos-unified-edge-telemetry.md and docs/sampling-cdm-gos-derivations.md moved to #517 (the GOS PR they actually describe) instead of living here. Part of splitting #515 into a reviewable stack (cleanup -> GOS -> NitroSketch sampling -> eval/docs) — the last PR in the stack.
