Keiko 0.3.16

Keiko's first public download release. Pick your platform below, unzip, and start it —
Node.js and the OpenCode sidecar are already inside; nothing else has to be installed.

Unsigned evaluation build (ADR-0121 D1, ADR-0163 D9). The bundles are sealed, so macOS
will not report a damaged app, but they carry no Apple Developer ID, no notarization and no
Windows trusted publisher yet. That is why the first launch needs the one extra confirmation
described below. Every integrity digest, containment and provenance check stays enforced.

Keiko 0.3.16 Release Notes

High · Improvements

  • Every activity-log line carries a process id, an instance id and a gap-free sequence number, so an analyzer can order events exactly and detect any line that was dropped.
  • One correlation id follows a request from the browser through the BFF to every model-gateway call, retry and circuit-breaker transition, to WebSocket sessions and to the background jobs it spawns; a background job also names the request that started it.
  • A chat error now shows a Support ID you can quote; the same id is on every server line of that request.
  • Request lines record the matched route template, the query parameter names, the response size and whether the client abandoned the request; every event stream ends with a line stating how many frames and bytes were sent and why it closed.
  • keiko support export writes one support file — redacted log lines of the last seven days, the product version and platform, and a content-free fingerprint of each local store — and keiko support analyze reconstructs per-request timelines from it; the export never modifies, migrates or unlocks a store.
  • Errors carry a Keiko-code stack (package and file positions, never absolute paths) and a closed error classification; provider errors record the HTTP status and retry-after; rate limits, key resolution, keychain fallbacks, encryption migrations and store opens leave body-free evidence.
  • Console-only diagnostics (memory retrieval degradation, Figma snapshot failures, a crash on a directly launched keiko ui) now reach the activity log, and the operator's stderr diagnostic carries no more than the log does.
  • Browser-side failures are reported to the server as bounded, content-free notes joined to the request they belong to, behind a process-wide rate limit.

Install on macOS

  1. Download and unzip; double-click Keiko.app inside the extracted folder (moving it to
    /Applications first also works — the first start adopts it there).
  2. macOS will say it cannot verify the developer. Open System Settings → Privacy &
    Security    , scroll to Security, click Open Anyway, and confirm. One time only.
  3. Keiko installs itself to /Applications, starts, and opens at http://127.0.0.1:1983.

If a start fails, Keiko now says why in a dialog. Runbook:
macOS first-launch

Install on Windows

Run keiko-windows-x64-setup.exe (SmartScreen: More info → Run anyway), or unzip and start
Keiko.exe.
