Phase 4 of the rebrand cascade. Updates the default RUST_LOG filter
in src-tauri/src/lib.rs and all 'target: "magnotia_startup"' string
literals across src-tauri/src/lib.rs and src-tauri/src/commands/models.rs.
Default filter (before):
warn,magnotia=info,lumotia_lib=info,lumotia_audio=info,
magnotia_startup=info,lumotia_hotkey=info,lumotia_ai_formatting=info
Default filter (after):
warn,lumotia=info,lumotia_lib=info,lumotia_core=info,
lumotia_audio=info,lumotia_hotkey=info,lumotia_ai_formatting=info,
lumotia_llm=info,lumotia_storage=info,lumotia_transcription=info,
lumotia_startup=info
magnotia_startup was a logical tracing target (not a crate); renamed
to lumotia_startup for consistency. magnotia_lib was already renamed
to lumotia_lib in Phase 2. Added per-crate filter entries for parity
across the workspace.
cargo build --workspace passes. cargo test --workspace: 330 pass, 0 fail.

Replaces 22 production eprintln! sites with structured tracing events
across 8 files. Closes Area B of the post-prognosis residuals plan
(docs/superpowers/plans/2026-05-12-engine-slop-residuals.md).
Files touched (22 sites):
- crates/hotkey/src/linux.rs (2) — hotplug watcher degraded-mode warnings
- crates/ai-formatting/src/pipeline.rs (1) — LLM cleanup fallback warning
- src-tauri/src/commands/transcription.rs (1) — chunking dispatch info
- src-tauri/src/commands/diagnostics.rs (1) — crashes-dir setup warning
- src-tauri/src/commands/tasks.rs (1) — malformed feedback row warning
- src-tauri/src/commands/power.rs (3) — App Nap acquire/release/fail
- src-tauri/src/commands/models.rs (5) — Whisper warmup lifecycle
- src-tauri/src/commands/live.rs (8) — session start, chunk dispatch,
per-chunk delivery, inference errors, worker disconnects, listener
loss, status-channel cascade
Levels: error for unrecoverable failures (inference disconnect, panic,
status cascade), warn for recoverable degradation (LLM fallback,
malformed rows, App Nap fail, hotplug watcher fail), info for lifecycle
(session start, chunk processed, App Nap acquire/release, warmup
complete, chunking dispatch), debug for per-chunk noise (speech-gate
skip, chunk dispatch).
Two new dependencies and two new filter targets:
- tracing = "0.1" added to crates/hotkey and crates/ai-formatting
- Default EnvFilter in src-tauri/src/lib.rs::init_tracing extended with
magnotia_hotkey=info,magnotia_ai_formatting=info so the new targets
emit at the default level
Out of scope (intentional, left as-is):
- crates/mcp/src/main.rs — CLI binary, stderr is the log contract
(module docstring) so the JSON-RPC stdout stream stays clean
- crates/*/tests/*.rs and crates/core/examples/tuning_log_demo.rs —
test/example diagnostic output relies on --nocapture stdio semantics
Discovery during sweep (not fixed — separate follow-up): hotkey crate
has 6 existing log:: calls (log::error/warn/info/debug) but the
workspace builds tracing-subscriber without the tracing-log feature, so
those events are currently silent. Worth a follow-up to either add the
tracing-log bridge or migrate hotkey's existing log:: calls to
tracing::.
Verification:
- cargo fmt --all
- cargo check --workspace --all-targets — clean
- cargo test --workspace — 330+ tests, zero failures
- rg eprintln! src-tauri/src/commands/ crates/hotkey/src/ crates/ai-formatting/src/ — zero hits
Pre-existing working-tree churn in crates/llm/, src/lib/pages/,
src/lib/utils/saveMarkdown.ts and the untracked phase10a dogfood notes
deliberately left unstaged per Jake's instruction.

Sweep of registered-but-never-invoked commands surfaced by an audit
against the frontend invoke() call sites. Each was confirmed dead via
grep across src-tauri, src, and crates: no caller anywhere.
Removed commands:
- check_model, count_transcripts_command, get_profile_cmd,
install_update, list_feedback_examples_cmd (utility/CRUD shapes
never wired)
- save_audio, start_native_capture, stop_native_capture (native-capture
path superseded by the live transcription session)
- transcribe_pcm, transcribe_pcm_parakeet (PCM commands superseded by
live session; no frontend caller)
- close_preview_window (preview window is hidden via the
core:window:allow-hide capability, not the command)
Cascade in audio.rs (~430 lines removed):
- CaptureWorker, NativeCaptureState struct + impl, stop_worker,
append_recorded_chunk, MAX_NATIVE_CAPTURE_RETURN_SAMPLES,
persist_audio_samples
- The two cfg(test) tests that exercised stop_worker (the
recording_filename tests stay, supporting resolve_recording_path
which the live session uses)
Cascade elsewhere:
- FeedbackDto struct and its From<FeedbackRow> impl
- Stale storage imports in feedback.rs, profiles.rs, transcripts.rs
- tauri::Emitter import in transcription.rs
- app.manage(NativeCaptureState::new()) in lib.rs setup
generate_handler entries removed for all 11 commands. cargo check passes
cleanly with zero warnings; no tests reference any deleted symbols.

Delete the local duplicate fn and libloading dependency from src-tauri;
import the canonical implementation from magnotia-core::hardware instead.

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.
Auto-applied cargo clippy --fix across 11 files — needless return,
unnecessary cast, map_or simplification, repeat().take() → repeat_n(),
iter().any() → contains(), manual char comparison, lifetime elision,
push_str single-char, reference immediately dereferenced.
Also fixed three lints on file_storage.rs manually: two doc-list-item
overindentations, plus the same needless-return. Baseline main was
not clippy-clean with -D warnings before; after this pass one
needless_range_loop warning remains (live.rs:1089) that clippy's
suggested rewrite would make less readable — left for a dedicated
refactor session.
Build + workspace tests remain green (245 passing, 0 failing, 1
ignored).
get_runtime_capabilities was returning `accelerators = ["cpu",
"vulkan"]` and `whisper.supports_gpu = true` regardless of build
config or runtime state. On a macOS build it falsely advertised
"vulkan" (the backend actually resolves via MoltenVK as Metal); on a
whisper-disabled build it claimed GPU support for an engine that
hadn't been linked.
Added `compose_accelerators(whisper_enabled, loader_available, target)`
— a pure helper that always emits "cpu" first and appends the
platform-appropriate GPU name only when whisper is compiled in AND the
Vulkan loader resolves. `supported_accelerators()` wraps it with the
live `cfg!(feature = "whisper")`, loader probe, and target OS.
`get_runtime_capabilities` now calls `supported_accelerators()` and
sets `whisper.supports_gpu = cfg!(feature = "whisper")`. Parakeet
stays CPU-only.
Five tests in `commands::models::tests` cover the permutation matrix:
whisper on/off, loader present/missing, macOS vs other. Both feature
configurations (`--features whisper` and `--no-default-features`)
build and pass tests.
Macos Metal-loader resolution on real hardware stays on the
ship-gate checklist — the detection logic is verifiable from Linux
but runtime behaviour is not.

Review feedback: src-tauri/src/commands/models.rs was still naming
load_whisper unconditionally, so a --no-default-features workspace
build (kon-transcription without the whisper feature) would have
compiled the transcription crate cleanly but failed in the kon crate
as soon as it tried to resolve the load_whisper symbol.
Adds a matching [features] section to src-tauri/Cargo.toml:
- default = ["whisper"]
- whisper = ["kon-transcription/whisper"]
and declares the kon-transcription dep with default-features = false so
the feature actually propagates rather than being forced-on by the
child crate's default. Cfg-gates the load_whisper import in models.rs
and adds a companion match arm that returns a runtime error when the
feature is off, keeping the API shape intact.
Verified with both cargo build -p kon and cargo build -p kon
--no-default-features.
New crates/transcription/src/transcriber.rs defines a Transcriber
trait (Send supertrait for spawn_blocking travel) with
TranscriberCapabilities (sample_rate, channels, supports_initial_prompt).
TranscriberCapabilities.sample_rate is load-bearing for the upcoming
progressive WAV writer (#19).
Concrete impls:
- SpeechModelAdapter wraps Box<dyn transcribe_rs::SpeechModel + Send>
for Parakeet (and any future transcribe-rs-backed engine).
- WhisperRsBackend moves its transcribe_sync body into the impl,
widening the signature from &self to &mut self so per-call
WhisperState can be created cleanly through the trait object.
LocalEngine now holds Box<dyn Transcriber + Send>; dispatch in
transcribe_sync collapses from a match to a direct call. Adds
LocalEngine::capabilities() for the WAV-writer.
Cargo feature flag "whisper" (default on) makes whisper-rs, num_cpus,
and the whole whisper_rs_backend module optional. cargo check
--no-default-features -p kon-transcription now builds without pulling
whisper-rs-sys — the escape hatch brief item #6 / #13 called for on
Windows / non-AVX2 / cloud-only builds. load_whisper is cfg-gated
behind the same feature.
src-tauri/src/commands/models.rs load_model_from_disk returns
Box<dyn Transcriber + Send> instead of SpeechBackend; caller chain
(ensure_model_loaded, prewarm_default_model) is unchanged.
transcriber_trait_is_object_safe test lands alongside the trait as a
compile-time witness against future Self-returning / generic-method
additions.
Two new Settings → AI knobs that compose cleanly with what already
shipped (aiTier, LLM model, translator prompt framing).
**B.1 #15 — Named cleanup presets.** LlmPromptPreset enum
(Default / Email / Notes / Code) appends a short context hint onto
the CLEANUP_PROMPT just before generation. Presets shape tone and
structure ("email paragraph", "bulleted meeting notes", "preserve
technical terms") without licensing the content-editing the
translator-not-editor framing forbids. cleanup_transcript_text_cmd
now takes `preset: Option<String>` which runs through the new
LlmPromptPreset::parse (normalises aliases like "meeting-notes",
collapses unknown values to Default).
**A.1 #28 — Sequential-GPU guard.** New LocalEngine::unload drops
the backend + model_id so a subsequent load actually reclaims VRAM.
load_llm_model, load_model, and load_parakeet_model Tauri commands
grow an optional `concurrent: bool` argument. When concurrent is
Some(false), loading LLM first unloads whisper+parakeet, and vice
versa — prevents VRAM OOM on tight-VRAM setups. Default is the
previous parallel behaviour so nothing changes for multi-GB cards.
Transcribe-in-progress paths (transcribe_pcm, transcribe_file, live)
pass None, so mid-dictation model loads don't accidentally tear
down the LLM.
Settings UI (AI section):
- Cleanup preset segmented button + descriptive copy for each option.
- GPU concurrency segmented button with explicit trade-off text
("faster transitions vs fits in tight VRAM").
Frontend wiring:
- settings.llmPromptPreset flows from DictationPage's
cleanupTranscriptIfEnabled into the Tauri command.
- settings.aiGpuConcurrency flows from both DictationPage (auto-load
on record) and SettingsPage (manual load/unload buttons) as
`concurrent: "parallel" === true` to the load commands.
Tests: three new preset cases in crates/ai-formatting/src/llm_client.rs
(parse aliases, suffix non-empty for non-default, default suffix
empty). All 139 existing lib tests still pass.

prewarm_default_model loaded the model and returned. That moves the
model into RAM, but whisper.cpp still allocates its context window +
fills GPU shader caches on the first inference call — producing the
~4–5 s cold-start latency documented in ufal/whisper_streaming #96
and #135 that feels like "Kon dropped my first sentence."
Extend the pre-warm task: after engine.load, feed one second of
silence (16000 zero samples at 16 kHz) through transcribe_sync with
default options. Silence returns empty segments; the *work* is the
context allocation, which now happens at app boot rather than on the
user's first hotkey press.
Net: the user's first real dictation should complete within ~1.5× the
steady-state RTF they'll see on subsequent runs, satisfying the A.1
#23 acceptance criterion. No new public API; all inside the existing
spawn_blocking.

Extends get_runtime_capabilities() with three new fields:
- activeComputeDevice: {kind, label, reason} — "GPU (Vulkan)" on
the happy path, "CPU (fallback)" with a reason when the Vulkan
loader is absent at runtime. libloading::Library::new probes
libvulkan.so.1 / vulkan-1.dll / libMoltenVK.dylib per target OS.
- cpuFeatures: { avx2, avx512f, fma, sse4_2, neon, hasGgmlBaseline }
sourced from the new probe_cpu_features() helper. hasGgmlBaseline
is the one flag the Settings banner actually reads.
- parallelModeAvailable: placeholder false until Phase A.4 lands
the real GPU VRAM probe + GpuGuard semaphore permit logic.
Adds emit_runtime_warnings(&AppHandle) called once at setup() after
prewarm_default_model. Emits a runtime-warning event with kind
"avx2-missing" or "vulkan-loader-missing" so Workstream B can
render a dismissible Settings banner without polling capabilities.
Contract matches docs/whisper-ecosystem/workstream-A.md §Item #1 for
Workstream B to consume without waiting for Phase A.2 to land the
real whisper_print_system_info bridge.

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.

Second dogfood sprint. Headline fix: Linux now uses native KWin/Mutter
decorations instead of fragile frameless `startResizeDragging`, which
collapsed diagonal corner resize to a single axis and made drag feel
laggy. macOS / Windows keep custom chrome via `useCustomChrome` gate.
Other changes:
- Cross-window preferences sync via `kon:preferences-changed` Tauri
event — theme and font changes propagate live to float/viewer.
- Hotkey recorder rewritten to use capture-phase document listener
gated by $effect; button focus was unreliable in webkit2gtk.
- History page redesigned for cognitive-load hygiene: title-first
compact row, inline title input, Edit popout opening /viewer in
edit mode, clipboard export as .md with YAML frontmatter, manual
tag chips + + Add tag input, header tag filter (cap 7), global
Starred filter, `tag:xyz` search syntax.
- `deriveAutoTags` kept as empty hook for post-Task-7 LLM topic tags;
research found all previous auto-tag chips redundant with row UI.
- Viewer window adds edit mode with debounced-save textarea; native
title renamed to "Kon - Transcription Editor".
- Window minimums updated per GNOME HIG + WCAG reflow research:
main 960x600, float 360x480, editor 560x520.
- Microphone picker filters raw ALSA strings (hw:, plughw:, front:,
sysdefault:, null) and dedupes by CARD=X. New `description` field
on DeviceInfo reads /proc/asound/cards so Blue Yeti shows as "Blue
Microphones" instead of the short "Microphones" card name.
- GPU reporting fixed: get_runtime_capabilities now returns
accelerators=[cpu,vulkan] and whisper.supports_gpu=true, matching
the transcribe-rs whisper-vulkan feature linked unconditionally.
- ResizeHandles kept for macOS/Windows frameless: 12px edges, 20px
corners via CSS vars, pointerdown + setPointerCapture, corners
above edges in z-order, rendered as sibling (not child) of the
animated layout root so `position: fixed` is viewport-relative.
- Dueling drag-region handlers removed — `data-tauri-drag-region` and
manual `startDragging()` were stacked on the same elements; kept
the manual handler which has the button/input early-return logic.
See HANDOVER.md for the full session log and deferred items.

crates/storage/src/migrations.rs:
Replace naive sql.split(';') with split_statements() that tracks
BEGIN...END depth, so migrations containing trigger definitions
execute correctly instead of being split mid-block.
crates/transcription/src/lib.rs:
Re-export transcribe_rs::SpeechModel so callers in src-tauri can
reference it without adding transcribe-rs as a direct dependency.
src-tauri/src/commands/models.rs:
Use Box<dyn SpeechModel + Send> as the load_model_from_disk return
type, matching the trait object that transcription crates produce.
src-tauri/src/commands/transcripts.rs:
Remove the stale .map(|v| v as i32) casts on sample_rate and
audio_channels. InsertTranscriptParams now stores these as i64
(ebf449b), matching the i64 fields on CreateTranscriptRequest;
casting to i32 first would silently truncate large sample rates.

THE BRIEF:
For the friends beta we need verbal feedback AND technical feedback —
some bugs the user cannot describe but a stack trace can. Built it in
two layers, with Layer 3 deferred until there is real volume.
PRIVACY POSTURE (matches Kon's local-first positioning):
- All capture is to disk only. Nothing is transmitted.
- The manual report bundler shows the user exactly what would be
shared and lets them choose to copy / save it.
- No remote endpoint, no Sentry, no opt-out telemetry.
LAYER 1 — Always-on local capture:
- Rust panic hook (commands/diagnostics.rs::install_panic_hook) writes
each panic to ~/.kon/crashes/<unix-ts>-<short-id>.crash. Captures
thread name, OS/arch, RUST_BACKTRACE state, and the panic info.
Installed before tauri::Builder so it catches setup-time panics too.
- Frontend window.onerror + window.unhandledrejection in
src/routes/+layout.svelte forward to the new log_frontend_error
Tauri command, which inserts into the existing error_log SQLite
table. Best-effort: errors in the error handler itself are swallowed
so logging can never crash the app.
- Existing error_log table (migration v1) is now actually used —
closes the TODO from crates/storage/src/database.rs:409.
LAYER 2 — Manual diagnostic report:
- Settings → About → Diagnostics section: Generate report → Preview →
Copy / Save.
- Report is plain markdown so it pastes cleanly into email, Discord,
GitHub issues. Sections: app version + OS, sanitised settings JSON,
recent error_log rows, last 5 crash dumps with previews, log file
tail (8KB).
- Preview is shown in a <details> with the full text the user can
inspect before deciding to share.
- Save writes to ~/.kon/diagnostic-reports/kon-diagnostic-<ts>.md.
NEW FILES:
- src-tauri/src/commands/diagnostics.rs (panic hook + 5 Tauri commands)
CHANGES:
- crates/storage/src/file_storage.rs: crashes_dir() + logs_dir() helpers
- crates/storage/src/database.rs: ErrorLogRow + list_recent_errors()
- crates/storage/src/lib.rs: re-exports
- src-tauri/src/commands/mod.rs: + diagnostics module
- src-tauri/src/lib.rs: install_panic_hook() before Builder; 5 new
Tauri commands registered (log_frontend_error,
list_recent_errors_command, list_crash_files,
generate_diagnostic_report, save_diagnostic_report)
- src/routes/+layout.svelte: installGlobalErrorCapture() at mount
- src/lib/pages/SettingsPage.svelte: diagnostic state + buttons +
preview block at the end of the About section
cargo check -p kon-storage clean. Settings.svelte if/each balanced.
LAYER 3 (deferred):
- Optional opt-in remote reporting (self-hosted Sentry on Tartarus or
similar). Not for friends beta. Open up after volume justifies it.
