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.

End-of-phase cleanup of items flagged across review passes for tasks
1.1, 1.2, and 1.3:
1. crates/core/src/lib.rs: pub mod power moved to alphabetical
position (between paths and process_watch).
2. crates/core/src/power.rs: use statements moved to top of file
(above the PowerState enum) per Rust convention.
3. crates/core/src/power.rs: parse_power_state_from_dir docstring
tightened to acknowledge that read_dir.flatten() silently skips
per-entry errors. Theoretical hazard only on world-readable
sysfs, but the previous wording overstated the guarantee.
No behavioural change. All 40 magnotia-core tests still green.

The MIN_INFERENCE_THREADS, MAX_INFERENCE_THREADS, and
inference_thread_count() defined in constants.rs were superseded by
the equivalents in tuning.rs (Task 2.1) and are no longer called by
any production code. Both call sites (whisper backend Task 4.1, LLM
generate Task 5.1) have migrated.
Constants.rs now holds only audio/mel/RAM/VAD/download constants;
inference-tuning concerns live in tuning.rs.

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.

Adds a OnceLock<Mutex<HashSet>> cache in tuning.rs. inference_thread_count
now emits a single tracing::info! line the first time each
(workload, on_battery, gpu_offloaded) tuple is seen in the process,
recording the resolved thread count and which clamps fired (battery, gpu).
Also derives Hash on Workload and tightens the GPU clamp to only record
the "gpu" clamp when it actually reduces chosen. Smoke test added.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds battery-state awareness to the thread-count helper: when
probe_power_state() returns OnBattery, chosen is halved before the
[MIN, MAX] clamp. Also removes the leading underscore from the
workload/gpu_offloaded parameters (they are silenced via let _ = ...
until the GPU-clamp task).
New test battery_halves_thread_count verifies on_battery <= on_ac and
>= MIN when the host has more than MIN physical cores. Restructured
to sequential with_override calls (not nested) to avoid re-entrant
deadlock on power::TEST_LOCK.

Without a lock, env_var_bypasses_clamps (set_var + remove_var) and
matches_existing_clamp_when_no_clamps_apply (remove_var) race under
cargo's parallel test runner. Task 2.2 will add another remove_var
call, compounding the race.
Adds a #[cfg(test)] static THREAD_ENV_LOCK and a closure-style
with_thread_env_lock helper, mirroring power::with_override.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
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).

Cache sits between override resolution and platform_probe; override
paths (test + env-var) bypass it entirely so they always take effect
immediately. OnceLock<Mutex<Option<CachedState>>> initialised lazily on
first probe. Two test-only helpers (force_clear_cache, force_set_cache)
expose the cache slot for unit tests. Mutex import ungated — now used in
production cache code as well as test override.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
TEST_OVERRIDE and test_get_override are now #[cfg(test)]-gated and
the read in probe_power_state is wrapped in a #[cfg(test)] block,
so test scaffolding doesn't compile into production builds.
with_override now uses a drop-guard pattern so a panic inside body
still resets TEST_OVERRIDE, preventing stale state from leaking
into subsequent tests.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds the public probe entry point with two override mechanisms:
- In-process TEST_OVERRIDE slot serialised by TEST_LOCK mutex for
unit tests (avoids races with cargo's parallel runner).
- MAGNOTIA_POWER_STATE_OVERRIDE env var for integration tests set
externally.
Platform dispatch: Linux reads /sys/class/power_supply; all others
return Unknown. Five new override tests pass alongside the six sysfs
parser tests from Task 1.2 (12 total green).

Pure function takes a directory path and returns OnAc, OnBattery, or
Unknown by reading `type` and `online` files in each supply entry.
Matches the kernel ABI documented at
Documentation/ABI/testing/sysfs-class-power. Failure modes (missing
dir, unreadable files, malformed contents) all fall through to Unknown
rather than panicking.
Seven tests cover: Mains online, battery-only, USB-PD, empty dir,
missing dir, and malformed entries. All pass.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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.

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.
`detect_meeting_processes` is called every 15 s when meeting-auto-capture
is enabled. The previous `list_running_process_names` allocated a fresh
`sysinfo::System` per call and walked /proc cold; on a busy host
(~300 processes) that's ~50–100 ms of work, every poll, forever.
Add `kon_core::process_watch::ProcessLister`, a thin wrapper around a
long-lived `System` whose process table is refreshed in place. The Tauri
host holds one behind a `Mutex<ProcessLister>` in a new `MeetingState`
managed at app setup. The free `list_running_process_names` is kept as a
convenience that constructs a fresh `ProcessLister` per call — its only
remaining caller is the existing smoke test.
- ProcessLister + Default in crates/core/src/process_watch.rs.
- MeetingState in src-tauri/src/commands/meeting.rs; the command takes
it via `tauri::State` and locks for the duration of the snapshot.
- src-tauri/src/lib.rs registers MeetingState alongside the other
managed states.

2026-04-22 review MINORs and NITs:
- crates/core/src/providers.rs: delete entire module. SpeechToText /
TextProcessor / ProviderRegistry were forward-looking traits that
never got wired — the Transcriber trait in kon-transcription
(A.2 #13) has since superseded SpeechToText, and the Registry
pattern was redundant against LocalEngine. Keeping them as dead
public surface signalled future direction that is no longer
accurate.
- crates/core/src/types.rs: delete TranscriptMetadata. Forward-
looking struct with an unfulfilled TODO; storage has evolved
independently through v7/v8 migrations without adopting it.
- crates/ai-formatting/src/llm_client.rs: remove #[allow(dead_code)]
from CLEANUP_PROMPT and format_dictionary_suffix. Both are
actively called; the suppressions would hide future genuine
dead-code warnings in this regression-sensitive prompt file.
- src-tauri/src/commands/live.rs: remove #[allow(dead_code)] from
LiveStatusMessage. Every variant (Warning, Overload, Error,
Finished) is constructed in the module today.
- README.md: update kon-transcription row from "SpeechToText
trait" to "Transcriber trait" and mention the new streaming/
module.
Workspace test gate green (225 lib tests across all crates).
Extends hardware::CpuInfo with a CpuFeatures struct populated via
std::is_x86_feature_detected! on x86_64 and an architectural
assumption for aarch64 (NEON). Adds has_ggml_baseline() so callers
can cheaply ask 'will whisper.cpp / llama.cpp ship a fast path on
this CPU?' without knowing the arch-specific rule.
The point of #7 is giving the runtime a way to surface a clear
"non-AVX2 fallback" warning before the user hits a wall of silent
slowness. The banner itself ships in the next commit as part of
get_runtime_capabilities (item #1). Tests cover the baseline helper
on both x86 and non-x86 targets.

QC smoke sweep flagged two clippy -D warnings lints in code this branch
introduced:
- crates/core/src/process_watch.rs — collapsible_if on the meeting-pattern
match loop, merged the two conditions with &&.
- crates/mcp/src/lib.rs — let-else on the id unwrap that short-circuits a
notification, switched to ? since handle_message already returns Option.
All other clippy lints under -D warnings (audio/capture, hotkey/linux,
storage/file_storage, diagnostics, the duplicate-detection helpers in
live.rs) predate this branch and are out of scope.

Default off. When on, the layout polls detect_meeting_processes every 15s
with the user's app-name patterns. On a fresh match (edge-triggered — no
re-toast until the app goes away and comes back) we fire a reminder toast
that tells the user which meeting app appeared and their global hotkey. We
never start recording on this signal; the ideology rule says the user
decides. The signal is a single channel: process list match only — no mic
activity heuristic, no calendar.
Backend adds kon_core::process_watch::{list_running_process_names,
match_meeting_patterns} over sysinfo, exposed to the frontend as the
detect_meeting_processes Tauri command.
Settings ships two new fields — meetingAutoCapture (bool) and
meetingAutoCaptureApps (string[]) — with a comma-separated input in the
Output section. Default app list is ["zoom", "teams"], user-editable.

Parakeet-TDT scores 85 on any GPU-equipped English-capable system (Instant
speed + Great accuracy + GPU boost + headroom) vs ~75 for the best distilled
Whisper. A new test in recommendation.rs locks this in so future scoring
tweaks don't silently regress it.
FirstRunPage previously stored settings.modelSize by title-casing a lowercased
alias — which worked for Tiny/Base/Small/Medium but produced
"Whisper-distil-small-en" for the new distil ids. Swap to an id→label map
and pass the raw model id through to download_model/load_model; the backend
already accepts full ids via the whisper_model_id fallback.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two new registry entries (crates/core/src/model_registry.rs):
- whisper-distil-small-en — 336 MB, ~6× faster than whisper-small-en
- whisper-distil-large-v3 — 1.55 GB, near large-v3 accuracy at medium size
Both are whisper.cpp-compatible GGML binaries hosted on HF by the
distil-whisper org; no runtime change, just wider model choice. English-only
by design (matches upstream Distil-Whisper).
The Settings model picker widens to six options — Tiny, Base, Small,
Distil-S, Medium, Distil-L — ordered roughly by accuracy. Download/load
commands now take the resolved model id (whisper-distil-*) instead of the
lowercased label, so the frontend owns the label↔id mapping.

Major quality pass on top of Phase 2. Five substantive changes plus
cross-cutting touches across audio, hotkey, transcription, and Tauri
command layers.
Transcription quality
- Long-audio chunking in commands/transcription.rs: Parakeet and large
file transcription now chunk-and-recompose with overlap trimming, so
the live-path chunking advantage extends to file-based workflows.
- Stateful live speech gate in commands/live.rs on top of the earlier
duplicate-boundary filtering — distinguishes start-of-speech from
mid-speech and holds state across chunks.
Auto-learning corrections
- New crates/ai-formatting/src/correction_learning.rs: extracts user
text corrections from viewer edits and proposes additions to the
active profile's vocabulary.
- src-tauri/src/commands/profiles.rs bridge for frontend-driven
confirmation of learned terms.
- src/routes/viewer/+page.svelte hooks the learning path into the
segment-edit flow so corrections feed profile_terms without a
separate 'train this profile' UX.
Transcript profile provenance
- Migration v8 (crates/storage/src/migrations.rs) adds profile_id to
transcripts, defaulting to DEFAULT_PROFILE_ID so existing rows stay
valid.
- crates/storage/src/database.rs: TranscriptRow + CRUD carry profile_id.
- src-tauri/src/commands/transcripts.rs: add_transcript accepts and
persists profile_id.
- DictationPage.svelte + FilesPage.svelte send activeProfileId on
capture so learned corrections are attributed to the right profile.
Cleanup prompt contract
- crates/ai-formatting/src/llm_client.rs hardened: the CLEANUP_PROMPT
now specifies concrete do/do-not rules, ready for a real model-backed
cleanup pass. The llm_client is still a stub — kon-llm remains unwired
— but the prompt shape is final.
Cross-cutting polish
- Minor touches in audio (capture/decode/resample), hotkey (lib/linux/stub),
core, transcription (concurrency/model_manager/local_engine/whisper_rs),
and the rest of src-tauri/src/commands/*: error-path tightening, log
clarity, TS-migration follow-ups (@ts-nocheck additions for incremental
typing).
Verified locally: npm run check, cargo test -p kon-ai-formatting,
cargo test -p kon-storage, cargo test -p kon --lib commands::live::tests,
cargo check — all green.
Scope boundary: kon-llm crate is still a stub; task extraction remains
rule-based. Bundled local-LLM runtime is the next clean step and is not
in this commit.

The CTC model (onnx-community/parakeet-ctc-0.6b-ONNX) only has an encoder
— no decoder_joint or nemo128 preprocessor. transcribe-rs expects a TDT
transducer variant with all three. Switch to istupakov/parakeet-tdt-0.6b-v2-onnx
which has the correct int8 files.

Add kon-hotkey crate with evdev-based global hotkey capture that works on
Wayland (and X11). Patterns from whisper-overlay: per-device async listeners,
inotify hotplug with udev permission retry, watch channel for live config
updates. Frontend detects Wayland at startup and selects evdev or
tauri-plugin-global-shortcut automatically.
Model downloads now support HTTP Range resume for interrupted downloads and
optional SHA256 integrity verification (incremental, no second pass).

- Share single System::new_all() in probe_system() instead of calling it twice
- Rename CpuInfo::core_count to logical_processors (sys.cpus().len() returns logical, not physical)
- Add fallback arm to probe_os() for unsupported cfg targets
- Add serde::Serialize to KonError for structured frontend error reporting
- Annotate dead code (ProviderRegistry, TranscriptMetadata) with #[allow(dead_code)] + TODO comments
- Update downstream references in recommendation tests and tauri hardware command
