ORAG 0.5.0

[0.5.0] - 2026-10-20
ORAG v0.5.0. The setup page shows this computer and the answer models that fit it, and downloads the one the user picks: the default qwen3.5-4b-q4_k_m (recommended) or qwen3.5-9b-q4_k_m (larger, slower). Each tier has a RAM floor and a recommended RAM measured on Mac (Metal) and Linux (CPU); a hand-set generator is kept; the choice is written to config.toml only after the download verifies (steps 81-82). Packages are still unsigned.
Release gates on the candidate 0.5.0-alpha.1: real-model check unchanged from v0.4.1 (v02 hybrid in context 0.931, hybrid p95 14.4 ms on Metal; answers expected facts 0.925, abstention P/R 0.944/0.850, no uncited answer; seed recall@10 1.000); D-003 dense search at 100k p95 97.3 ms on Apple M5 Max and 226.3 ms on the Linux reference (both PASS). Answer time on a 4-vCPU CPU without a GPU is about 108 s (4B) and 194 s (9B), so GPU support for Windows and Linux is the next step.
