v0.14.1

🐛 Fixed

Runtime

  • Vault get retries once after a stale DEK wrap when master rotation commits mid-read. Concurrent reads return the intact value, not INVALID_KEY.

v0.14.0

✨ Added

Runtime

  • fx.json.stream(chunks) returns HTTP text/event-stream (data: frames, then data: [DONE]). Pass fx.stream(...) so tokens reach the client. JSON flows stay { data, error }.
  • HTTP requests install request.signal as the ambient abort. fx.ask, fx.stream, and fx.run cancel the provider fetch on client disconnect. Anthropic complete now forwards signal.
  • ai.model({ driverId }) opens that protocol instead of the app default. fx.stream(model, { via }) advances after a retryable failure before the first chunk.
  • ai.mcpServer(name, { url | command, auth, tools }) consumes an external MCP server. Allowlisted tools join fx.ask / ai.agent on the same fx.call path as mcp:<server>/<tool> (OKE1007 when undeclared).

Console — Flows & traces

  • mcp:<server>/<tool> calls draw one AI node per server and a call-blue edge. Trace events label them **MCP call**.

Console — Observability

  • The AI rail counts call effects on mcp: resources next to asks.

Console — Units & Call API

  • Units chips for MCP tools read Call github → create_issue and use the AI icon.

♻️ Changed

Runtime

  • Prompt budget.maxCostPerCall and agent maxCostPerRun are enforced at runtime. Over-budget asks journal budget_exceeded and do not advance via. Disconnect AbortError is not retryable.
  • Clock next-run math uses crontab (*/15, @hourly, IANA timezone). Leader instances wake in-process; store, lease, catch-up, and Console pause stay source of truth. Fall-back overlap fires once.
  • SSE responses disable the 10s idle timeout so a quiet token stream is not reset. Ollama NDJSON and prompt eval files parse via native JSONL.
  • Cloud AI drivers preconnect the provider origin. Memory pressure closes idle keep-alive sockets, not in-flight requests.
  • Redis KV and signal bind typed eval / xadd / xreadgroup / xack / xgroup.

Dev, Keel & create-oke

  • Minimum Bun is ≥ 1.4.0. Generated Dockerfiles pin oven/bun:1.4.

Docs

  • AI and fx pages document fx.json.stream, HTTP disconnect abort, runtime budget enforcement, and ai.model({ driverId }).
  • AI and MCP pages document ai.mcpServer consume vs the served :6535 endpoint, plus Console graph / Units / traces surfaces.
  • Signal once / broadcast / live examples now split writer (fx.emit in a Flow) from listener (on(signal, flow) vs bus.live()), and Flow no longer claims there is no subscribe for live replay.
  • Installation, Store Image, and Clock pages match Bun ≥ 1.4.0. Clock DST follows crontab (once on overlap, shifted on a spring gap).

🐛 Fixed

Runtime

  • Streaming HTTP runs record duration at stream close, not at handler return. Traces stay empty while the stream is open; the completed row covers the full generation, not time-to-first-byte.
