Slipstream 0.3.2

Slipstream 0.3.2

Canonical product repository: Schero94/slipstream

Highlights

• Pure native stack: Slipstream remains llama.cpp/PGRN plus oMLX/PGRN. It
  bundles no Ollama runtime and creates no second model store.
• Bounded llama prompt cache: the app launcher now supplies
  --cache-ram 512, replacing llama.cpp's 8192 MiB default with a measured
  ceiling that cannot silently consume most of a small Mac's free RAM.
• Conditional tool-schema warm-up: when Tools are enabled, llama.cpp warms
  Slipstream's exact get_current_time + calculator schema after readiness.
  The UI exposes warming, ready and soft-failure states; disabling Tools or
  stopping the server aborts the request.
• Evidence before rollout: the optimization is not copied to oMLX because
  its two qualified short-schema requests remained cold. Each engine keeps the
  path its measurements support.

Measured effect

The product configuration was Qwen3.6-35B-A3B on an external SSD, 10 GiB PGRN
expert cache, 3 GiB RAM reserve, 512 MiB llama prompt cache, MTP and four PGRN
I/O threads.

Request	TTFT	Cached prompt	Result
hidden one-token schema prime	23.36 s	0 / 355	PASS
first visible calculator(19+23)	4.73 s	337 / 361	exact tool + args
get_current_time()	2.46 s	337 / 355	exact tool + {}

First visible tool TTFT fell 79.7% relative to the cold schema prefill. RSS
was 15.18 to 15.42 GiB, free+inactive memory stayed near 6.6 GiB and swap stayed
exactly 1148.12 MiB. The hidden request consumes one completion token in
llama.cpp's accounting; its generated text is discarded and never enters chat
history. A max_tokens: 0 follow-up was rejected because the OpenAI chat
adapter still returned and accounted one token.

Validation

• 183/183 complete Rust workspace tests pass.
• 96/96 Tauri/Rust tests pass.
• 39/39 Python runtime, storage and qualification tests pass.
• All six Node UI contracts and the atomic oMLX bootstrap test pass.
• Chromium passed desktop 1440×1000 and mobile 390×844 tool warm-up gates:
  2/2 transitions, exact request contract, no horizontal overflow and no
  console warnings or errors.
• The updated GitHub Pages source passed the same desktop/mobile browser sizes:
  v0.3.2 and the measured TTFT are visible, horizontal overflow is zero, and
  the console has no warnings or errors.
• DMG CRC and ZIP integrity pass. The mounted app contains version 0.3.2, 477
  resource files, all 16 manifest-required components, no Python bytecode cache
  and arm64 app/server/converter/uv binaries.
• /Applications/Slipstream.app was upgraded from 0.3.1 to 0.3.2. A real launch
  produced the registered app process; quit released it and ports 8080/8081
  remained free. The prior app is recoverable from the user's Trash.

The node archive reports version 0.3.2 and contains the arm64 binary, launchd,
systemd and non-root Docker templates plus the community-mesh operations guide.
Linux remains supported from source and through the documented Docker/systemd
path; this release does not claim a cross-compiled Linux binary or CUDA result.

Known boundaries

The app is unsigned and unnotarized. Community traffic is encrypted in transit,
but the chosen inference worker decrypts and sees the prompt; sensitive and
secret work stays local by default. Public discovery, NAT traversal and relay
fallback are not yet deployed, so community peers still need a known, reachable
address.
