jars	3c47000ea9	chore(core): add tuning_log_demo example for live heuristic validation ... Run with: cargo run -p magnotia-core --example tuning_log_demo Initialises a tracing-subscriber fmt layer so the inference_thread_count INFO event is rendered to stderr. Exercises all 8 (workload, gpu_offloaded) combos under three power scenarios: AC override, battery override, and the real sysfs probe. Used to validate the heuristic on 2026-05-09 against the spec's 6c12t truth table — all 6 rows match. Adds tracing-subscriber as a [dev-dependencies] for the example.

jars	b991355cb0	feat(core): port vulkan_loader_available from src-tauri ... Adds libloading = "0.8" to magnotia-core dependencies and moves vulkan_loader_available() into magnotia-core::hardware so non-Tauri crates (transcription, llm) can probe the Vulkan loader without depending on the Tauri binary. Test asserts the call completes on any host regardless of whether libvulkan is installed. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-09 12:02:39 +01:00
jars	504ba0a361	feat(core): tuning module with Workload + helper skeleton ... Adds crates/core/src/tuning.rs with MIN/MAX_INFERENCE_THREADS consts, Workload enum (Llm/Whisper), and inference_thread_count() helper matching the existing constants::inference_thread_count clamp behaviour. Three unit tests pass. tracing dep added to Cargo.toml (used by future tasks). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-09 11:38:07 +01:00
jars	1f3496e4ed	feat(core): add PowerState skeleton in new power module ... Introduces crates/core/src/power.rs with the PowerState enum (OnAc / OnBattery / Unknown) and a unit test confirming the three variants are distinct. Registers the module in lib.rs and adds tempfile = "3" to dev-dependencies for use in later tasks. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-09 11:14:24 +01:00
jars	4cb954ece4	perf: route whisper + llm n_threads through physical-core helper ... Both inference call sites previously called `num_cpus::get()` (logical thread count). Established whisper.cpp / llama.cpp guidance is that SMT siblings contend for shared FPU resources during heavy F16/F32 matmul, so going past physical core count anti-scales. Empirical sweep on Whisper Tiny / 11s JFK clip / Ryzen 5 4650U (6c12t): n_threads | xc_time | RTF | speedup_vs_1 ----------|---------|--------|------------- 1 | 0.33s | 0.030 | 1.00x 2 | 0.33s | 0.030 | 1.00x 4 | 0.30s | 0.028 | 1.09x 6 | 0.32s | 0.029 | 1.04x 8 | 0.31s | 0.028 | 1.06x 12 | 0.32s | 0.029 | 1.03x Tiny doesn't scale (work dominated by overhead) but the larger Whisper variants and Qwen LLMs do. Sources: whisper.cpp #200, #1033, #1252, #403; llama.cpp #3167, #572. Changes: - crates/core/src/constants.rs: * MIN_INFERENCE_THREADS lowered 4 → 2 (research-derived floor) * MAX_INFERENCE_THREADS = 8 added (research-derived ceiling) * inference_thread_count() rewritten: - reads MAGNOTIA_INFERENCE_THREADS env var (override) - num_cpus::get_physical() with available_parallelism fallback - clamped to [MIN_INFERENCE_THREADS, MAX_INFERENCE_THREADS] - crates/core/Cargo.toml: + num_cpus = "1" - crates/transcription/src/whisper_rs_backend.rs: call site uses helper. - crates/llm/src/lib.rs: call site uses helper. - crates/transcription/Cargo.toml: drop num_cpus from [features] + [dependencies] (production no longer needs it). Move to [dev-dependencies] for tests/thread_sweep.rs only. - crates/llm/Cargo.toml: drop num_cpus = "1" (no longer used directly). Per-machine maps (after this patch): Ryzen 5 4650U 6c12t → 6 big-iron 12c24t → 8 (clamp; users can override) cheap 2c2t laptop → 2 1c container/VM → 2 Adds crates/transcription/tests/thread_sweep.rs — env-gated like jfk_bench, prints the table above against any model + WAV. Useful for re-baselining on new hardware or when tuning the clamp values. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-05-09 09:26:23 +01:00
Claude	89c63891fa	chore: rebrand from Kon/Corbie to Magnotia ... Replace all instances of the legacy product names "Kon" and "Corbie" with "Magnotia" across user-facing copy, code identifiers, package names, bundle ids, file paths, and documentation. Preserves the unrelated "konsole" (KDE terminal) reference and the parent CORBEL company name. - Renames 10 Rust crates (kon-* → magnotia-*) and the tauri binary - Updates package.json, tauri.conf.json (productName + identifier) - Renames CSS classes (kon-rh-* → magnotia-rh-*) and animations - Renames brand and roadmap docs - Regenerates Cargo.lock and package-lock.json Verified: svelte-check passes; pure-rust crates compile under new names.	2026-04-30 13:06:55 +00:00
jake	6588130e36	feat(kon): add core crate — types, traits, hardware, model registry, recommendation ... - Value objects: ModelId, EngineName, Megabytes, AudioSamples, Segment, Transcript - KonError enum with thiserror - Constants centralised: audio pipeline, VAD, RAM thresholds, inference threading - SpeechToText and TextProcessor provider traits with ProviderRegistry - Unified model registry (Whisper tiny/base/small/medium + Parakeet CTC int8) - Hardware detection: probe_ram, probe_cpu, probe_gpu (stub), probe_os - Recommendation engine: score_model (pure function), rank_recommendations (sorted) - 5 tests passing, clippy clean Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-16 20:27:27 +00:00
jake	9926a42b7a	feat(kon): scaffold hybrid modular workspace ... - Cargo workspace with 6 domain crates: core, audio, transcription, ai-formatting, storage, cloud-providers - Minimal Tauri shell (lib.rs + main.rs) with plugin registration - Svelte 5 frontend copied from Ramble v0.2 - All crates compile as empty stubs - App identifier: uk.co.corbel.kon Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-16 20:21:38 +00:00
