headroom 0.1.0

A two-second on-device probe that tells your app how fast an LLM of a given size will decode on this phone, whether it fits, and on what basis.

0.1.0

First release.

• Headroom.probe() runs the Headroom Swift package's probe on iOS (Metal STREAM ceiling, C STREAM triad, memory, thermal, power, device) and the same C triad with Android's memory, thermal, battery and device facts on Android, returning a typed ProbeReport with a basis on every figure.
• ProbeReport.estimate() is a Dart port of the package's estimator and memory-fit maths, driven by a copy of its calibration.json; predictions on Android carry basis unknown until an Android calibration exists.
• ModelSpec.tinyLlama1_1BQ4_0 and ModelSpec.qwen2_5_0_5BInstructQ4_K_M, the two presets verified from GGUF headers.
• tool/sync_native.sh keeps the native sources identical to the package.
