feat: quantcpp recommend + ask_verified Python API + CI smoke test

unamedkr · claude · unamedkr · commit 393bdd55f090 · 2026-04-13T12:48:11.000+09:00
Three issues addressed: 1. #88 quantcpp recommend — vocab-aware model selection CLI - `quantcpp recommend` (balanced/speed/quality) - Shows vocab size, speed estimates, all models comparison - Checks if recommended model is cached 2. #90 Confidence score — ask_verified() Python API - Model.ask_verified(context, question) → (answer, confidence) - Self-check (ANSWER/NONE) + coherence check (YES/NO) - Confidence: 0.9 (verified), 0.5 (uncertain), 0.1 (coherence NO) - Same mechanism as RLV verifier, now in public API 3. #87 ClawTeam CI smoke test - bench/rlv/eval/ci_smoke.py — fast regression check - Tests: imports, CLI commands, ctest, memory leaks - Designed for GitHub Actions PR gating (~2min) Fixes #88, #90 Refs #87 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
