wasmagent v0.2.0

— 2026-06-12

First public npm release. Establishes the package set and the four
strategic axes (S1–S4 in ROADMAP.md). All packages share this
version line for the initial publish; subsequent releases will
version per-package via changesets.

Added

• 30 published packages: core, three kernels (kernel-quickjs,
  kernel-pyodide, kernel-wasmtime, plus kernel-remote),
  upstream adapters (aisdk, mastra-sandbox), eight model
  presets, the mcp-server, devtools, evals-runner, and
  supporting tool packages (tools-browser, tools-rag,
  tools-web, ui-cards, ui-cards-react, react, cli,
  cloudflare-worker, a2a, ag-ui, agent-prompts,
  otel-exporter).
• Three-tier code-execution kernel matrix (in-process / WASM /
  remote) with a unified CapabilityManifest enforced cross-kernel.
• ObservationalMemory with a byte-stable observer prefix designed
  for Anthropic prompt-cache hits.
• Quality Runners: SelfConsistencyRunner, ReflectRefineRunner,
  BudgetForcingRunner, ParallelForkJoinRunner.
• Speculative DAG scheduler (Scheduler + SimpleIR +
  deriveDependencies).
• Multi-criteria JudgeScorer for LLM-as-judge evals.
• Code-mode MCP server (@wasmagent/mcp-server ≥ 0.3) with a
  two-tool surface (docs_search + execute_code) shown to use
  ≤14% of the tokens of direct-MCP at N=30 tools.
• Zero-deploy local Studio: RunsAggregator + EventLogReplay +
  agentkit devtools CLI serving an inline HTML dashboard.
• Statistically rigorous evaluation harness (@wasmagent/evals-runner)
  with McNemar exact, Wilson CI, paired bootstrap, six reference
  benchmark suites, and Pareto-front rendering.
