Sprint 0512 · Ops & Offline · Bench (190.G)

Topic & Scope

  • Build and capture performance benchmarks for graph, UI interactions, impact index, policy deltas, and reachability scoring to support offline/ops readiness.
  • Target harnesses under src/Bench/StellaOps.Bench with reproducible datasets.
  • Working directory: src/Bench/StellaOps.Bench.

Dependencies & Concurrency

  • Upstream data: graph fixtures (SAMPLES-GRAPH-24-003), reachability schema (Sprint 0400/0401), policy delta inputs.
  • UI bench depends on BENCH-GRAPH-21-001/002 harness foundation.

Documentation Prerequisites

  • docs/07_HIGH_LEVEL_ARCHITECTURE.md
  • docs/modules/platform/architecture-overview.md
  • docs/modules/graph/architecture.md (for graph bench scenarios)
  • docs/modules/signals/architecture.md (for reachability benches)
  • docs/modules/policy/architecture.md

Delivery Tracker

# Task ID Status Key dependency / next step Owners Task Definition
1 BENCH-GRAPH-21-001 BLOCKED Need graph bench harness scaffolding (50k/100k nodes) Bench Guild · Graph Platform Guild Build graph viewport/path benchmark harness (50k/100k nodes) measuring Graph API/Indexer latency, memory, and tile cache hit rates.
2 BENCH-GRAPH-21-002 BLOCKED Blocked on 21-001 harness Bench Guild · UI Guild Add headless UI load benchmark (Playwright) for graph canvas interactions to track render times and FPS budgets.
3 BENCH-GRAPH-24-002 BLOCKED Waiting for 50k/100k graph fixture (SAMPLES-GRAPH-24-003) Bench Guild · UI Guild Implement UI interaction benchmarks (filter/zoom/table operations) citing p95 latency; integrate with perf dashboards.
4 BENCH-IMPACT-16-001 BLOCKED Impact index dataset/replay inputs not provided Bench Guild · Scheduler Team ImpactIndex throughput bench (resolve 10k productKeys) + RAM profile.
5 BENCH-POLICY-20-002 BLOCKED Policy delta sample inputs missing Bench Guild · Policy Guild · Scheduler Guild Add incremental run benchmark measuring delta evaluation vs full; capture SLA compliance.
6 BENCH-SIG-26-001 BLOCKED Reachability schema/fixtures pending Sprint 0400/0401 Bench Guild · Signals Guild Develop benchmark for reachability scoring pipeline (facts/sec, latency, memory) using synthetic callgraphs/runtime batches.
7 BENCH-SIG-26-002 BLOCKED Blocked on 26-001 outputs Bench Guild · Policy Guild Measure policy evaluation overhead with reachability cache hot/cold; ensure ≤8 ms p95 added latency.

Date (UTC) Update Owner
2025-11-18 Marked BENCH-GRAPH-24-002, BENCH-IMPACT-16-001, BENCH-POLICY-20-002, BENCH-SIG-26-001/002 as BLOCKED pending fixtures/datasets and reachability schema. Bench
2025-11-18 Normalised sprint to standard template; renamed from SPRINT_512_bench.md. Ops/Docs

Decisions & Risks

  • Graph/UI benches depend on large fixtures (SAMPLES-GRAPH-24-003) and graph overlay schema; risk until fixtures land.
  • Reachability benches depend on runtime/static schema alignment (Sprint 0400/0401) and fixture relocation.
  • Policy/Impact benches require deterministic datasets; ensure no online dependencies.
