Details 
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.

fdf27db0a1 perf+fix: DMABUF default on Linux, popout ACL fixes, plugin version sync, JFK bench fixture 
Bundled work from a low-end laptop (Ryzen 5 4650U / Vega 6 / Linux Mint
22.2 / X11) profiling pass.

perf: WEBKIT_DISABLE_DMABUF_RENDERER=1 default on all Linux
  Previously only set on Wayland sessions. Empirically it's a
  significant idle-cost win on integrated GPUs in either session type:
  env-var matrix (release binary, 75s settle, 10s jiffies CPU sample)
  showed magnotia idle CPU 12.30% → 2.80% of one core and idle GPU
  17% → 10% on this hardware. Users can opt back in by exporting
  WEBKIT_DISABLE_DMABUF_RENDERER=0. The Wayland-only XWayland
  fallback (GDK_BACKEND=x11, WINIT_UNIX_BACKEND=x11) is unchanged.

fix: secondary-windows ACL — allow set-always-on-top
  The float window's pin toggle calls setAlwaysOnTop() but the
  secondary-windows capability didn't permit it, so the popout was
  stuck always-on-top regardless of the pin state. Adds the
  core:window:allow-set-always-on-top permission. Narrow scope.

fix: guard registerGlobalHotkey against non-main webviews
  Cross-window settings sync via localStorage can re-fire the
  $effect(() => settings.globalHotkey) callback inside popout webviews
  where the main layout's registerGlobalHotkey is reachable. Adds an
  early-return when the current window label is not "main", so the
  popout doesn't trigger an ACL-denied register/unregister and the
  user no longer sees a spurious "Hotkey not registered" toast when
  popouts are open. Keeps the global-shortcut perm scoped to main.

build: pin @tauri-apps/api 2.10.1 + @tauri-apps/plugin-dialog 2.7.1
  Match the Rust crate versions tauri-cli's version-mismatch check
  enforces during release builds. Without this, `npm run tauri build`
  exits 0 silently while emitting an Error and never producing
  binaries.

test: add crates/transcription/tests/jfk_bench.rs
  Reproducible RTF regression fixture. Env-gated on
  MAGNOTIA_WHISPER_TEST_MODEL + MAGNOTIA_WHISPER_TEST_AUDIO so it
  never runs in CI without setup. Loads the JFK WAV inline (no hound
  dep), times model load + cold + warm transcribe, prints SUMMARY.
  Baselines on this hardware:
    --release --features whisper:               cold RTF 0.054, warm 0.050, RSS 125 MB
    --release --features whisper,whisper-vulkan: cold RTF 0.029, warm 0.028, RSS 125 MB
  Vulkan on RADV/Vega 6 nearly halves transcription latency for
  Whisper Tiny — useful baseline for Phase 10 hardware-recommendation
  scoring.

2dfd7167fd fix(a11y): Toggle aria-invalid briefly when async onChange rejects

When an async onChange handler rejects, the toggle snapped back to its
previous value silently — screen reader users had no signal that the
action failed, only that the toggle suddenly returned to its original
state. Now aria-invalid="true" exposes the failure on the role=switch
button for 1.5s after rejection, so assistive tech announces the error.
Self-clears via setTimeout; no API change for callers.

aecb191705 refactor(theme): tokenise hard-coded amber shadows and reconcile duplicate @font-face declarations 
Hard-coded rgba(214,132,80,X) shadows were tied to the dark-theme accent
and stayed off-hue in light mode (where the accent is a darker #a3683a).
Six tokens added to app.css @theme and mirrored in the light-theme block
plus design-system/colors_and_type.css:

  --shadow-accent-sm     0 0 8px   0.25 alpha  Toggle on-state
  --shadow-accent-md     0 4px 16px 0.3       ModelDownloader card
  --shadow-accent-lg     0 4px 20px 0.3       DictationPage record button
  --shadow-accent-glow   0 0 8px   0.4        progress-bar glow
  --shadow-accent-pill   0 1px 4px 0.3        SegmentedButton pill
  --shadow-accent-raised 0 2px 8px 0.2        FilesPage browse tile

Migrated seven sites: Toggle, SegmentedButton, ModelDownloader (x2),
FilesPage (x2), DictationPage record button, SettingsPage locale pill.
Focus-ring shadows (0_0_0_3px_rgba(...,0.1)) left alone — handled in
parallel via the --accent-shadow-focus token.

@font-face: app.css and colors_and_type.css both declare the same five
fonts. Duplication is unavoidable because preview/*.html loads the
design-system file directly without Vite, so it cannot share the
runtime declarations. font-weight ranges and font-style reconciled to
match exactly (Atkinson 200-800 not 400-700, JetBrains gains font-style:
normal); src URLs intentionally differ (root-absolute vs relative).
Comments added to both copies explaining the contract.

f4c0635549 fix(a11y): guard sidebar-toggle keypress against custom widgets and scope transcript font-size effect 
- Extend isInputFocused to also bail when document.activeElement sits
  inside a custom widget with role combobox/listbox/radio/switch/menuitem/tab
  so single-letter shortcuts like '[' do not collapse the sidebar while
  focused on SegmentedButton, ZonePicker, etc.
- Move the transcript font-size CSS variable write from documentElement
  to document.body. Consumers inherit body styles, and scoping the write
  there avoids invalidating root-level styles every time fontSize changes.

47b005ad70 fix(a11y): bump record button to 48x48 and announce Recording stopped to screen readers 
Record button bumped from 40x40 to 48x48 (WCAG 2.5.5 AA requires 44x44; 48 chosen as forgivable oversize for the most-touched control). Inner stop-square and record-circle bumped 14x14 to 16x16, Loader2 16 to 18, to keep the visual ratio.

Recording-status sr-only live region now announces both transitions: "Recording started" on start and "Recording stopped" on stop, with the stop message clearing after 1200ms so the live region does not hold stale text. Transition tracked via a plain let prevRecording (not $state) since it is bookkeeping and must not retrigger the effect. aria-atomic="true" added so the whole region re-reads on update.

ca3a55320b fix(a11y): bump all text below 12px to 12px floor and promote tertiary-on-body to secondary 
Brand guidelines (docs/brand/magnotia-brand-guidelines.md §4) say "Never go
below 12px for any text" and "tertiary text must be ≥18px bold or ≥24px
regular". Audit found 246 sub-12px className sites and 166 cases of
text-text-tertiary paired with body sizes.

Bumped text-[9/10/11px] → text-[12px] across 26 .svelte files in src/lib
and src/routes. Promoted text-text-tertiary → text-text-secondary at body
sizes (12-14px) where context allowed; left placeholder pseudo-states,
ternary-conditional inactive states, and line-through "done" states alone
(8 residual pairings, all decorative).

Affects neurodivergent users on 1366×768 budget hardware most directly.

5778696140 feat(dictation): surface "Talk now, think later" empty state and hide post-transcript actions 
Reduces first-run cognitive load. Save / Copy / Clear / Export now appear only
once the user has a transcript or is recording, sliding in via animate-fade-in
(brand --duration-ui + ease-out-quart). Template and Extract Tasks remain
always-visible because they shape transcription rather than acting on completed
content.

Empty state now leads with the catchphrase as a brand statement
(font-display italic 28px) with the hotkey hint demoted to body-font tertiary.
EmptyState gains an optional headline prop; callers without it render unchanged.

d2f64a231d feat(theme): bump accent chroma, push sensory zones apart, richer status tokens 
Phase 10b colour push: theme reads as Magnotia, not "subdued generic dark".
Same lightness band as Phase 10a (AA preserved), more chroma across accent,
status tokens, and zone surfaces.

Dark accent: #c98555 -> #d68450 (subtle/hover/glow recomputed).
Light accent: #a06a3e -> #a3683a.
Dark status: success #7ec89a -> #5fc28a, danger #e87171 -> #e85f5f,
warning #e8c86e -> #e8be4a.
Light status: success #2f7549 -> #1f7344, danger #a83838 -> #b32626,
warning #b89a3e -> #a08a1f.

Sensory zones pushed further apart so each zone reads as its own
environment: cave cools toward blue-grey, energy warms toward red-orange,
reset cools toward green. AA on body text verified for every Card surface
in both themes.

Stale accent rgba (201,133,85) replaced with new (214,132,80) across nine
files. --shadow-accent in colors_and_type.css mirrored.

No secondary tint token added: Magnotia's identity is amber-as-the-only-
meaningful-colour. Cheaper to add a second meaningful colour later if a
real need appears than to dilute the discipline now.

Default surfaces, text tokens, and borders untouched per scope.

ec09f8ffdb feat(settings): finalise polish — autostart Toggle dedupe, AI Default/Advanced split, vocab consistency, model ETA, privacy badge, group icons

Details 
Six changes, one coherent polish pass on SettingsPage:

1. Autostart toggle dedupe. The 27-line custom button that mirrored
   Toggle's markup to dodge a bind:checked race is gone. Toggle's new
   async onChange + snap-back covers the OS round-trip; setLaunchAtLogin
   re-throws on failure so Toggle reverts checked. autostartSyncing
   state retired.

2. AI Assistant Default/Advanced split. Cleanup preset and GPU
   concurrency moved into a nested SettingsGroup title="Advanced",
   closed by default. The Assistant page now leads with four
   first-decision controls (tier, model picker, status, prewarm) and
   parks the tuning knobs behind a disclosure. Search keywords cascade
   from the Advanced group up to AI Assistant up to AI & Processing.

3. Vocabulary disclosure consistency. The hand-rolled Profiles and
   Templates sub-panels (with their own ChevronRight buttons +
   showProfiles/showTemplates state) are now nested SettingsGroups.
   The count badges live in the description slot ("3 profiles ·
   custom vocabulary..."). showProfiles, showTemplates, and the
   ChevronRight import retired.

4. Model-download ETA in Settings. Both whisper and LLM download
   chips now show "{percent}% · {bytes} / {total} · {duration} left",
   reusing formatDuration from utils/time.ts. New formatBytes +
   etaSecondsFromPercent helpers in SettingsPage; bytes pulled from
   the existing emit payload (DownloadProgress snake_case for whisper,
   done/total for the LLM event). FirstRunPage already does the
   timestamp-based ETA; we mirror its shape.

5. Privacy badge in sticky header. Single chip "100% local · no
   telemetry · no cloud" added next to the Settings heading using
   bg-accent-subtle + text-text-tertiary. The longer About list
   stays put as the deep-dive.

6. SettingsGroup icons on the seven top-level groups. Mic, BookOpen,
   Type, Sparkles, SquareCheck, Clipboard, Sliders — paired with the
   existing literal text titles per the icon-with-label brand rule.
   Inner nested groups stay icon-free.

Verification: npm run check returns 0 errors, 0 warnings.

aa1ba48e07 feat(card): add tone (subtle, danger) and elevation (raised) variant props 
Both props default to current behaviour, so all existing call sites render
unchanged. Subtle uses bg-bg-elevated for quieter empty-state contexts;
danger uses bg-danger/5 + border-danger/30 for calm caution panels (not
red-alert loud, matching brand). Raised layers shadow-md on top of the
existing low-contrast shadow for floating or detached surfaces.

3a27031eba feat(settings-group): add optional icon prop and tighten title/description rhythm 
Title bumped to font-semibold so it scans first; description gets tracking-wide
plus mt-1 for cleaner rhythm. Chevron alignment shifted from mt-0.5 to mt-1 to
match the new spacing. Optional `icon` prop renders a Lucide component between
the chevron and the title block at 16x16, text-tertiary, no colour change on
open. Layout is preserved exactly when no icon is passed.

aebf6cd149 feat(toggle): add disabled, loading, and async onChange props 
Extends the shared Toggle with three optional props while keeping the
existing bind:checked path untouched for current call sites.

- disabled: dims the control, sets aria-disabled, and early-returns on click.
- loading: forces a Loader2 spinner inside the thumb, applies cursor-wait
  and aria-busy, and blocks interaction. Cursor-wait wins over disabled's
  not-allowed when both are set, matching loading-precedence guidance.
- onChange(next): when supplied, replaces the immediate flip. Promise
  returns drive an internal pending flag so the toggle renders loading
  while the handler resolves; on resolve checked flips, on reject the
  toggle snaps back. Synchronous handlers flip immediately after the call.

Brand motion preserved: 150ms duration, cubic-bezier(0.2, 0.8, 0.2, 1),
no transition-all.

5e3a9f9f42 fix(ui): promote modal overlay to token, lift modal above grain, dedupe FilesPage drop-zone

- MorningTriageModal: replace inlined rgba scrim with var(--color-overlay-dim), drop backdrop-blur-sm (brand opposes glassmorphism by default), bump container to z-[60] so it sits above the .grain z-50 overlay.
- FilesPage: collapse two near-identical drop-zone blocks into one bordered region with conditional inner content; preserves isDragOver hover behaviour and aria region.

13af425dfa fix(hotkey): surface Esc-to-cancel hint and replace recording-keyframe reuse with success flash 
Two scoped fixes to HotkeyRecorder:

- Append "Esc to cancel." to the recording prompt so the existing Escape
  handler is discoverable. srStatus already mentions Escape; no harmonisation
  needed.
- Replace animate-pulse-warm on the captured state with a static
  bg-success/10 + border-success/40 flash. pulse-warm is the
  recording-active keyframe; reusing it for the saved state muddled the
  visual vocabulary. The global * transition rule already animates
  background-color and border-color over --duration-ui (150ms) with the
  brand cubic-bezier ease, so no new keyframe is needed and prefers-reduced-motion
  is honoured automatically. Also swapped transition-all for transition-colors
  to comply with the no-transition-all brand-motion rule.

a4cca58289 fix(history): replace native confirm() with inline two-click confirmation 
Native window.confirm() is OS-styled and breaks the warm-amber UI
tone with an abrupt brutalist modal. The brand voice is "calm,
informative, solution-first; never blame the user", and confirm() is
none of those.

Replaced both destructive paths (Clear All, Delete N selected) with
a two-click inline pattern: first click arms the trigger and morphs
it into "Delete X? [Confirm] [Cancel]" inline pills; auto-cancels
after 4s so a user who walked away doesn't return to a primed delete
button. No new modal, no new component, no new dependency.

Both timers are cleared in onDestroy so unmounting the page mid-arm
doesn't leak.

e857a814ad fix(ui): remove side-stripe borders in favour of subtle bg tints 
Side-stripe borders (border-left: 2px or 3px in an accent colour, with
the rest of the element having no border) are the textbook AI-coded-IDE
"selected-state" pattern. The brand vocabulary is colour-tint and
chevron, not stripe-and-fill.

Replaced eight sites:
- VirtualSegmentList active/match/default segment rows: bg-accent/10,
  bg-warning/10, hover:bg-hover (drop the stripes; bg-warning bumped
  /5 → /10 so it's visible without the stripe doing the work).
- viewer/+page.svelte: same pattern as VirtualSegmentList.
- TasksPage profile-list tabs: bg-accent/10 + font-medium for active,
  hover:bg-hover for inactive. rounded-md added so the tint follows
  the row outline.
- ToastViewport: replaced border-left + variant colour with full 1px
  border + bg tint + border-color tint (color-mix() with the matching
  semantic token at 35% / 10%). Also removed the orphan --moss /
  --signal / --ember tokens — they were not defined in app.css and
  fell back to hex literals.
- preview/+page.svelte: dropped the phase-coloured left stripe and
  the borderColorClass derivation; the header already has a pulsing
  dot / animated bars / spinner for each phase, so the stripe was
  redundant.

360e5457dc fix(copy): replace em-dashes in user-facing strings with commas/periods 
Per the project's no-dashes feedback rule (see CORBEL-Main memory
feedback_no_dashes.md), em-dashes in user-visible copy are the single
biggest "AI wrote this" surface tell. Forty-two occurrences across ten
files: ten in SettingsPage's group descriptions and option labels
(audio device picker, vocabulary help, prompt placeholders, model
descriptions), four in FirstRunPage's setup steps, three in
DictationPage / FilesPage / Energy chip tooltips, plus the privacy
bullets ("100% offline, no Python required, no cloud, no accounts,
no telemetry"), the rejection toast, MicroSteps thumb labels, and the
shutdown ritual prompts.

Replacement rule: subordinate-clause em-dashes followed by lowercase
become commas; sentence-break em-dashes followed by capitals become
full stops. Code comments left intact.

One non-em-dash regression caught while reviewing: TasksPage's energy
filter "no selection" placeholder showed "—" as a literal label; the
script changed it to a comma which read as a UI bug. Replaced with
"Any" instead.

637ed89eac feat(settings): ship search filter that opens matching groups 
The settingsSearch state was declared in Phase 9c with a comment
describing the intended behaviour but no <input> bound to it. With 21
SettingsGroup instances and a 2,261-line page, finding any specific
control required scrolling and opening every group. For the
neurodivergent audience this is exactly the cognitive-load failure
the brand commits to avoiding.

Added a sticky search input at the top of the page (paired with the
"Settings" title in a single sticky header that bg-bg-matches the
page so groups don't bleed under it). Each SettingsGroup now passes
through searchMatches against its title, description, and a curated
keyword string. Parent groups inherit their children's keywords so a
search for "GPU" expands AI & Processing and the AI Assistant inner
group together.

Updated SettingsGroup to push prop changes to the DOM via $effect:
the native <details> element's open attribute is mutated by user
clicks outside Svelte's reactive graph, so a parent prop change
needs to force-sync. User-driven toggles where the prop value didn't
change keep their local state because $effect only re-runs on diff.

Verified live: baseline shows 3 groups open (Transcription, Terms &
profiles, Capture & export), "GPU" opens AI & Processing + AI
Assistant only (other 19 closed), "ritual" opens Tasks & Rituals +
Rituals only, X-button clear restores baseline.

7a21d0c7fc fix(ui): sync stale shadow rgba from pre-Phase-10a amber to current accent 
Eighteen sites across SegmentedButton, Toggle, HotkeyRecorder,
ModelDownloader, FilesPage, and SettingsPage hardcoded the old amber
rgba(232,168,124,...) for focus rings, glows, and progress bars. After
the Phase 10a a11y darkening of --accent to #c98555, the inline shadows
no longer matched the accent fill they were paired with, so every
focused input rendered a glow at a noticeably different hue from its
border.

Replaced all of them with the current accent rgba(201,133,85,...).

Toggle component also had two motion violations: an active:scale-95
press-shrink and a cubic-bezier(0.16,1,0.3,1) (ease-out-expo) thumb
transition. Both replaced with the brand's --ease curve
(0.2,0.8,0.2,1) and the scale dropped, in line with the record-button
fix in the previous commit.

Removed redundant inline transition-duration overrides on FilesPage
Browse button (the global * rule already sets --duration-ui) and on
ModelDownloader's primary CTA (also dropped its active:scale-[0.97]).

a545c7a12d fix(dictation): drop bouncy press motion and update record-button glow rgba 
Record button had active:scale-[0.93] transition-all, which contradicts
the brand motion guideline ("never bounce, slow, calm, deliberate"). The
record button is the most-touched control in the app; a 7% press-shrink
on it sets the wrong tone for everything else.

Removed the scale transform, removed the inline transition-duration
override (the global * rule in app.css already animates the named
properties at --duration-ui). Also updated the inline shadow rgba from
(232,168,124,0.3) to (201,133,85,0.3) so the glow tracks the new
a11y-darkened accent fill instead of the pre-Phase-10a amber.

f274611d23 fix(app): scope user-select:none to chrome elements only 
Body had user-select:none globally so users could not copy error
strings, model paths, profile names, transcripts, status messages,
or any text into search or another tool. The brand essence is
"clarity without friction" and this was friction.

Body now defaults to user-select:text (the standard for text content),
and the chrome elements that should never be drag-selected (button,
summary, role=button|switch|tab|menuitem, data-no-select) opt out.

Verified live: body=text, button=none, paragraph=text (inherited).

fdeda6c642 fix(design-system): sync colors_and_type.css to app.css authoritative tokens 
The runtime app reads tokens from app.css @theme; this file ships values
to the buildless preview pages under design-system/preview/*.html.
Several values had drifted from the Phase 10a a11y darkening done in
app.css, so the previews showed brighter accents and lighter tertiary
text than what users actually see.

Aligned: dark --text-tertiary, dark --accent (+ hover/subtle/glow/
border-focus/shadow-accent), light --text-tertiary, light --accent
(+ hover/subtle/glow), light --success, light --danger.

Header banner now states the file's role explicitly so future edits
don't recreate the drift.

2f85ec5806 fix(settings): rename text-error/border-error to text-danger so error states actually render 
The Tailwind v4 @theme block defines --color-danger as the semantic error
token, and 15+ files across the codebase use text-danger consistently.
SettingsPage was the lone outlier with five text-error / border-error
sites (audio devices, profile delete, vocabulary, term delete, diagnostic
report). Without a --color-error token, those utilities resolved to the
default text colour, so error messages rendered in warm cream instead of
red. Verified live via Playwright probe before and after.

README LLM-formatting section now states four Qwen tiers (Qwen3.5 2B /

four-tier registry. The whisper-ecosystem context doc gets the same
refresh and cites unsloth as the GGUF source.

Older roadmap and Phase-0 audit docs left untouched — they are dated
historical artefacts and rewriting them would muddy the audit trail.

0f105f0e15 chore(llm): update callers for renamed model variants 
Picks up the registry rename in the front-end and Tauri command layer:

- src/lib/types/app.ts: LlmModelIdStr now lists the four new ids
  (qwen3_5_2b / qwen3_5_4b / qwen3_5_9b / qwen3_6_27b).
- src/lib/pages/SettingsPage.svelte: LLM_MODELS table rebuilt with
  four tiers (Minimal / Standard / High / Maximum), matching subtitles
  and download-size copy. selectedLlmModelId fallback, hardware-warning
  thresholds, tier-availability check, and ensureRecommendedLlmTier
  fallback all retargeted at the new ids. The Maximum tier surfaces a
  64 GB / 24 GB warning so users with mid-range hardware see honest
  expectations.
- src-tauri/src/commands/llm.rs and commands/tasks.rs: doc-comment
  examples refreshed (Qwen3 4B → Qwen3.5 4B, Qwen3's tokenizer →
  Qwen's tokenizer — the BPE family is shared).
- src/lib/stores/llmStatus.svelte.ts: chip-detail example updated.

cargo build --workspace clean. cargo test --workspace clean.
npx svelte-check reports one pre-existing error in vite.config.js
(unused @ts-expect-error directive, dates back to the original
scaffold commit 9926a42); not introduced here, out of scope to fix.

699cb7e08e feat(llm): bump model registry to Qwen3.5 + Qwen3.6 family (4 tiers) 
Replaces the three older Qwen3 variants with a four-tier ladder spanning
a wider hardware range:

- Qwen3_5_2B_Q4   (Minimal, 8 GB RAM, ~1.3 GB download)
- Qwen3_5_4B_Q4   (Standard, 16 GB RAM / 6 GB VRAM, ~2.7 GB) — DEFAULT
- Qwen3_5_9B_Q4   (High, 32 GB RAM / 12 GB VRAM, ~5.7 GB)
- Qwen3_6_27B_Q4  (Maximum, 64 GB RAM / 24 GB VRAM, ~17 GB)

All four GGUFs sourced from unsloth's HF org with pinned commit SHAs.
Sizes and SHA256 hashes verified against the live X-Linked-Etag /
X-Linked-Size headers on the LFS CDN. Q4_K_M quantisation throughout
(common sweet-spot for cleanup + task extraction).

recommend_tier rewritten to span four bands; default_tier moves from
the old 4B-Instruct-2507 to Qwen3.5 4B. The 27B Maximum tier honestly
needs 64 GB RAM to run without partial offload — surfaced in the
description string so the Settings UI can warn realistically.

In-tree smoke tests (smoke.rs, content_tags_smoke.rs) updated to
reference the new smallest tier so a developer's MAGNOTIA_LLM_TEST_MODEL
points at the cheapest GGUF to download. Crate description in
crates/llm/Cargo.toml refreshed to mention the new family.

NOTE (out of scope; not fixed): the size_bytes / sha256 / hf_url
methods could collapse into a single LlmModelMetadata table to remove
four parallel match arms. Layer 2 cleanup, separate session.

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.

Final impeccable detect cleanup. The launch-at-login toggle thumb in the
Tasks & Rituals section was using cubic-bezier(0.34, 1.56, 0.64, 1) — the
same overshoot bounce that was replaced in Toggle.svelte by commit
6469663. Match the convention here so all toggle animations use the
same exponential ease.

Single-line CSS change. Visual smoke not exercised because the dev
server is winding down between subagents; npm run build confirms the
file still compiles clean.

eb3d2f90ab refactor(settings): regroup SettingsPage into 7 progressive-disclosure groups 
Phase 9c follow-up. The 2309-line hand-rolled accordion is replaced with
seven SettingsGroup-wrapped top-level groups, each containing the
relevant existing sub-sections as nested SettingsGroups:

1. Audio — microphone (input device).
2. Vocabulary — terms & profiles, profiles & templates (legacy manager
   moved in here so all profile / vocabulary state lives together).
3. Transcription — engine, format mode, model management, compute device,
   language. Defaults to open to preserve the prior accordion's landing.
4. AI & Processing — post-processing toggles, AI Assistant tier and
   model management, if-then implementation rules. AI Assistant and
   if-then rules moved out of their original positions to sit alongside
   the deterministic post-processing toggles.
5. Tasks & Rituals — rituals (incl. launch-at-login, kept bundled with
   the existing Rituals UI block to avoid splitting that block), tasks
   page (sparkline), nudges.
6. Output & Capture — read aloud (TTS, lazy-loaded on first open via the
   new SettingsGroup `onopen` hook), capture & export.
7. Appearance & System — global hotkey, appearance (theme/zone/font/
   locale), accessibility, about (engine status + diagnostics).

Deviations from Codex's 7-group spec:
- Launch-at-login stays inside the Rituals sub-group (was bundled there
  in the existing markup; relocating would require splitting the
  Rituals UI block, which is out of scope for this pass).
- Profiles & Templates legacy manager pulled into the Vocabulary group
  rather than appearance/system.

Implementation notes:
- SettingsGroup gains an optional `onopen` callback prop, fired once on
  the first closed→open transition. Used by Read aloud to lazy-load TTS
  voices and by AI & Processing to refresh LLM status. Replaces the
  former toggleAiSection / toggleReadAloudSection imperative handlers.
- The centralised openSection state is removed; each <details> manages
  its own disclosure.
- Tokens are inherited from app.css; the prior global token darkening
  (commit 2da0a5b) covers all section labels via the existing utility
  classes — no per-component label-class swaps were added.

Search box deferred to a follow-up commit. Forcing `open=true` on
SettingsGroup based on a filter input would require either a controlled
`open` prop or a {#key} re-mount strategy, both of which add risk to
this restructure pass.

Tauri-bridged commands cannot be exercised in browser-only `npm run
dev`; structural verification done via npm build, npm check, and a
live dev server fetch of /settings. Real persistence smoke needs a
tauri dev session.

Verification:
- cargo fmt --check: pre-existing whitespace diffs in src-tauri/src/
  live.rs and src-tauri/src/lib.rs only (untouched by this commit).
- cargo clippy --all-targets -- -D warnings: clean.
- cargo test: 283 tests pass.
- npm run check: 1 pre-existing error in vite.config.js:5; 0 new.
- npm run build: clean.

6469663c25 fix(ui): impeccable detect — perf + taste touch-ups across four components 
Mechanical fixes from `npx impeccable detect`:

- Sidebar.svelte: replace `transition: width, min-width` on the aside
  with a wrapping CSS-grid container animating `grid-template-columns`.
  Avoids per-frame layout cost from animating `width` directly.
- MorningTriageModal.svelte: swap pure `bg-black/50` overlay for the
  brand deep-neutral `rgba(26, 24, 22, 0.5)` (#1a1816 @ 50%). TODO left
  in source to promote this to a `--color-overlay` token in app.css.
- Toggle.svelte: drop bouncy `cubic-bezier(0.34, 1.56, 0.64, 1)`
  (1.56 overshoot) for ease-out-quart `cubic-bezier(0.16, 1, 0.3, 1)`.
  Still snappy, no overshoot — better fit for a toggle.
- TasksPage.svelte: same grid-template-columns refactor as Sidebar
  for the list-sidebar `transition: width` declaration.

Verification:
- npm run check: 1 pre-existing error (vite.config.js:5), 1 unrelated
  warning in SettingsGroup (out of scope, owned by parallel subagent).
- npm run build: clean.
- cargo clippy --all-targets -- -D warnings: clean (with LIBCLANG_PATH).
- cargo test --workspace: 283 passed, 0 failed.
- cargo fmt --check: pre-existing diffs in main.rs / lib.rs (no Rust
  files were touched in this commit).

Manual smoke deferred — `npm run dev` is in use by the SettingsPage
subagent, so the build-clean signal is the proxy.

22d554e85b fix(a11y): T4 / T7 / H3 — energy chip + filter pill + per-row checkbox 
Phase 10a a11y audit (2026-04-29):

T4: Energy radio chip text in dark mode read at 3.48:1 (text-text-tertiary
  on chip bg). Bumped non-selected chips to text-text-secondary so the
  hierarchy still reads but the resting state clears AA.

T7: Selected energy radio (and the match-my-energy toggle next to it)
  used bg-accent/15 — visually indistinguishable from surrounding bg in
  dark theme. Bumped to bg-accent/25 and added a 1px accent/30 border on
  the selected state so the selected pill is unambiguous in both themes.

H3: Per-row bulk-select checkbox in HistoryPage rested at opacity-50,
  which drops the unchecked outline below 3:1 over bg-bg-card. Bumped
  base opacity to 70%; hover/selected states unchanged.

Note on T6 (energy radiogroup arrow keys): verified the keyboard handler
in TasksPage. It is attached to the wrapper element with role=radiogroup,
and arrow-key events on the focused radio child bubble up to the wrapper
because the focused radio sits inside it. The handler reads
settings.currentEnergy (not the focused element) to pick the next index,
then focuses the new radio explicitly via querySelector. ArrowRight /
ArrowLeft / ArrowUp / ArrowDown / Home / End all wired correctly. No
change needed — pattern is sound.

Resolves: T4, T7, H3. T6 verified working as-is.

fa734c869f fix(a11y): P5 / G4 — add focus trap to MorningTriageModal 
Phase 10a a11y audit (2026-04-29) flagged the morning triage modal as
having role="dialog" and aria-modal="true" but no focus trap, so Tab
leaks out to the sidebar/page beneath. Escape-to-close was already
wired and is preserved.

Behaviour now matches the W3C dialog pattern:

- On open, capture the invoking element (document.activeElement) and
  move focus to the first focusable inside the dialog.
- Tab cycles forward; Shift+Tab cycles backward. Wrap-around between
  first and last focusable.
- On close, restore focus to the captured invoker.
- The dialog container itself gets tabindex=-1 so it can hold focus
  if no children are focusable (e.g. during the loading state).

The focusable selector excludes aria-hidden elements and elements with
no offsetParent (display:none / visibility:hidden), so dynamic content
between loading -> tasks -> action buttons stays in sync.

Resolves: G4.

d089fdb37f fix(a11y): P3 — drop focus:outline-none on inputs; restore global :focus-visible 
Phase 10a a11y audit (2026-04-29) flagged seven inputs across the app
that strip the global 2px :focus-visible outline (defined in app.css:251)
without providing a comparable replacement. Net effect: keyboard users
see at most a 1px border-colour shift on focus, sometimes nothing.

The fix removes the focus:outline-none override so the global rule
applies. Affected inputs:

- FilesPage: file-transcript textarea (F2).
- TasksPage: search input, quick-add input, inline list-edit, new-list
  input (T1, T2, T3, plus the new-list rename input).
- HistoryPage: top search, inline title rename, tag-add (H1).
- ImplementationRulesEditor: trigger/surface/task selects + speak-line
  input (S7).
- TaskSidebar, WipTaskList: quick-add inputs (S8).

The 1px focus:border-accent on inputs that had it is retained as a
secondary cue; the global 2px ring is now the primary indicator and
matches button focus across the app.

Resolves: F2, T1, T2, T3, H1, S7, S8.

2da0a5bab8 fix(a11y): P1/P2/G3/FR3 — darken tertiary/accent/success/danger tokens to meet AA 
Phase 10a a11y audit (2026-04-29) flagged 14 contrast failures rooted in
four tokens. Single token-level change resolves them across both themes.

P1 (text-text-tertiary): #8a8578 → #6b6557 light, #716b60 → #8c8678 dark.
  Token was used as both decorative tertiary and body-grade label, so it
  must clear AA 4.5:1. Lifts ratios from ~3.3-3.7:1 to ~4.7-5.0:1 across
  the surfaces it appears on (sidebar tagline + footer, dictation footer,
  files hint, tasks empty state, history empty state, settings descriptions
  and section labels, shutdown trail copy, first-run skip links).

P2 (color-accent): #b87a4a → #a06a3e light, #e8a87c → #c98555 dark. White
  text on accent fill (Browse Files button, selected segmented pills,
  link-style buttons) now clears AA. Dark theme worst case was 2.03:1 on
  Browse Files; the new dark accent clears 4.5:1 with white. Subtle/hover/
  glow tokens recomputed off the new bases.

G3 (color-success light): #3d8a5a → #2f7549. Sidebar Ready status text
  and other success copy on cream surfaces clears AA.

FR3 / D4 (color-danger light): #c44d4d → #a83838. Browser-mode warning
  and hardware-probe error copy clears AA on cream.

Resolves: G1, G2, G3, D1, D2, D3, D4, F1, F3, F4, T5, H2, S1, S2, S3,
SD2, FR2, FR3.

# Corbie Handover — 2026/04/25
# Magnotia Handover — 2026/04/25
Phase 9 session. Spec + plan written from scratch and committed; plan corrections layered in after critical review against the actual codebase (Codex was unreachable for cross-model review, three retries failed at the ChatGPT-account-entitlement layer). Sub-phases 9a + 9b + sparkline polish landed end to end. Sub-phase 9c reduced to the Phase 8 carryover bug fix; sub-phase 9d's walkthrough sweeps deferred to Phase 10a QC.
## Rebrand note
Product rename **Kon → Corbie** still in flight. Copy in new docs is "Corbie"; codebase paths / package names / repos still carry `kon`. No rebrand work this session. See `~/.claude/projects/-home-jake-Documents-CORBEL-Main/memory/project_corbie_rebrand.md`.
Product rename **Magnotia → Magnotia** still in flight. Copy in new docs is "Magnotia"; codebase paths / package names / repos still carry `magnotia`. No rebrand work this session. See `~/.claude/projects/-home-jake-Documents-CORBEL-Main/memory/project_magnotia_rebrand.md`.
## What shipped this session
### 9a — Export plumbing
- `write_text_file_cmd` Rust command in new `src-tauri/src/commands/fs.rs`, with two unit tests (UTF-8 round-trip + bad-parent error path). Registered in `invoke_handler!`. `tempfile = "3"` added as `[dev-dependencies]` on the kon crate.
- `write_text_file_cmd` Rust command in new `src-tauri/src/commands/fs.rs`, with two unit tests (UTF-8 round-trip + bad-parent error path). Registered in `invoke_handler!`. `tempfile = "3"` added as `[dev-dependencies]` on the magnotia crate.
- `src/lib/utils/saveMarkdown.ts` utility centralises `suggestedFilename`, `saveTranscriptAsMarkdown`, `exportTranscriptsToDir` (directory-mode bulk export with in-batch collision suffixing).
- HistoryPage `exportMarkdown` no longer copies to clipboard; it opens the OS save dialog and writes the file. Cancel returns silently.
- HistoryPage gained a slim leading checkbox per row, a bulk-action toolbar (select-all / clear / export / delete), `Esc` to clear, `Cmd/Ctrl+A` to select-all-visible when focus is inside the list and not in a text input.
### 9b — LLM content tags
- `kon-llm` exports a new `ContentTags { topic, intent }`, an `INTENT_CLOSED_SET`, an `is_valid_intent` helper, a `CONTENT_TAGS_SYSTEM` prompt and a `CONTENT_TAGS_GRAMMAR` GBNF (recursive style matching the existing `TASK_ARRAY_GRAMMAR`).
- `LlmEngine::extract_content_tags` method follows the same render-chat → generate → JSON-parse shape as the existing `cleanup_text` and `extract_tasks`. Truncates to the trailing 2000 chars on a UTF-8 boundary; max_tokens 96 is enough for the JSON envelope. Smoke test in `crates/llm/tests/content_tags_smoke.rs` is gated on `KON_LLM_TEST_MODEL` matching the Phase 8 pattern.
- `magnotia-llm` exports a new `ContentTags { topic, intent }`, an `INTENT_CLOSED_SET`, an `is_valid_intent` helper, a `CONTENT_TAGS_SYSTEM` prompt and a `CONTENT_TAGS_GRAMMAR` GBNF (recursive style matching the existing `TASK_ARRAY_GRAMMAR`).
- `LlmEngine::extract_content_tags` method follows the same render-chat → generate → JSON-parse shape as the existing `cleanup_text` and `extract_tasks`. Truncates to the trailing 2000 chars on a UTF-8 boundary; max_tokens 96 is enough for the JSON envelope. Smoke test in `crates/llm/tests/content_tags_smoke.rs` is gated on `MAGNOTIA_LLM_TEST_MODEL` matching the Phase 8 pattern.
- `extract_content_tags_cmd` Tauri wrapper bridges through `state.llm_engine` with the standard `spawn_blocking` + `PowerAssertion` guard.
### 9b structural — migration v14 + persistence wiring
A correction layered in after the critical-review pass discovered the original Task 9 was assuming a writable `saveHistory()` path that turned out to be a no-op stub.
- Migration v14 adds `transcripts.llm_tags TEXT NOT NULL DEFAULT ''`.
- `kon-storage` `database.rs` SELECT statements include the column. `TranscriptRow` + `transcript_row_from` carry it. `update_transcript_meta` accepts an `Option<&str>` for `llm_tags` (sixth optional, `#[allow(too_many_arguments)]` keeps clippy happy without inverting the signature into a struct).
- `magnotia-storage` `database.rs` SELECT statements include the column. `TranscriptRow` + `transcript_row_from` carry it. `update_transcript_meta` accepts an `Option<&str>` for `llm_tags` (sixth optional, `#[allow(too_many_arguments)]` keeps clippy happy without inverting the signature into a struct).
- `commands/transcripts.rs` `TranscriptDto` + `UpdateTranscriptMetaRequest` add `llm_tags`; `update_transcript_meta_cmd` forwards.
- Frontend types: `TranscriptEntry.llmTags: string[]`, `TranscriptRow.llmTags: string`, `ContentTags`, optional `TranscriptMetaPatch.llmTags`.
- `mapTranscriptRow` hydrates `llmTags`. `saveTranscriptMeta` now also forwards `llmTags` payloads. `buildFrontmatter` unions auto + manual + LLM tags into the exported markdown frontmatter.

The original Phase 9 spec + plan committed at `49a795f` + `48d3db7` had three mismatches against the actual codebase, surfaced by a critical-review pass before execution. Layered as a corrections appendix in commit `3eb24f2`:
1. `kon-llm` is `LlmEngine::generate(prompt, config)` synchronous, not the speculated `LlamaEngine::generate_chat(messages, config).await`.

2. `AppState.llm_engine: Arc<LlmEngine>` is direct, not behind a `RwLock`.
3. **Structural** — `transcripts.llm_tags` requires a real SQLite migration plus Tauri command extension because the frontend `saveHistory()` is a no-op stub. Original plan assumed `manualTags`-mirroring would suffice. Migration v14 + `update_transcript_meta` extension landed as a new task to cover this. Picked up the latent `manualTags` persistence bug for free.

1. **Manual dogfood walkthrough.** Cannot be driven by an automated agent. When opening Magnotia next:
- Export one transcript via the History "Export .md" button — save dialog opens, file written to chosen path. Cancel — no toast, no fallback.
- Select 3 history rows via checkboxes — toolbar surfaces, "Export selected" writes one .md per row to a chosen folder, collisions suffixed " (2)" etc.
- Click "Tag" on one row — within a few seconds, dashed `topic:*` and `intent:*` chips appear. Click a chip — it moves into `manualTags` (solid accent chip). Page refresh — both `manualTags` and `llmTags` survive (this is the persistence-fix outcome).

### Frontend (src/)
- **SvelteKit + Svelte 5 runes** (`$state`, `$derived`, `$effect`).
- **Tailwind CSS 4** for styling, with a Lexend/Atkinson/OpenDyslexic type system.
- **Secondary windows** (`/float`, `/viewer`, `/preview`) use named layouts (`+layout@.svelte`) to skip the main shell and run chrome-free.
- **Reactive stores** (`src/lib/stores/page.svelte.ts`): `settings`, `profiles`, `tasks`, `history`, `taskLists`, `templates`, `page`, `toasts`, `preferences`.
- **Reactive stores** (`src/lib/stores/`, one file per store): `page.svelte.ts` (central app state; transcripts, profiles, taskLists, templates, etc. live as fields here), `preferences.svelte.ts`, `profiles.svelte.ts`, `toasts.svelte.ts`, `focusTimer.svelte.ts`, `llmStatus.svelte.ts`, `nudgeBus.svelte.ts`, `implementationIntentions.svelte.ts`, `completionStats.svelte.ts`, `speaker.svelte.ts`.
- **i18n**: `svelte-i18n` with en/es/de locales at `src/lib/i18n/locales/`. Scaffolding only — strings migrate to translation keys incrementally.

# Phase 0 — Cartography
*Acquisition-grade audit, Phase 0 deliverable. Date: 2026-04-30. Branch: `claude/rebrand-to-magnotia-UWYkg`.*
This is a survey, not a verdict. It maps what exists, sizes the surface, and flags every place the README disagrees with the code. Phase 1 (lean-pass) and Phase 2 (architecture conformance) consume this as input.
---
## 1. Workspace shape
| Layer | Path | Notes |
|---|---|---|
| Rust workspace root | `Cargo.toml` | `members = ["src-tauri", "crates/*"]`, `resolver = "2"` |
| Tauri app crate | `src-tauri/` | Library `magnotia_lib` + binary `magnotia` |
| Library crates | `crates/*` (×9) | See §3 |
| MCP standalone binary | `crates/mcp/` | Bin `magnotia-mcp` (separate process from main app) |
| Svelte frontend | `src/` | SvelteKit, Svelte 5 runes, Tailwind 4 |
| Static assets | `static/`, `src-tauri/icons/`, `src-tauri/resources/` | |
**Binaries shipped (2):** `magnotia` (Tauri app), `magnotia-mcp` (stdio MCP server).
---
## 2. Lines of code
| Area | LOC | Files |
|---|---:|---:|
| `crates/` (Rust, all 9 crates) | 13,261 | 52 |
| `src-tauri/` (Rust) | 8,330 | 27 |
| Frontend (Svelte/TS/JS, excl. design-system) | 15,192 | ~80 |
| `src/design-system/` (reference kit, not live code) | 1,412 | — |
| **Total active** | **~36,800** | |
### Largest files (top complexity candidates)
| LOC | File |
|---:|---|
| 2,534 | `crates/storage/src/database.rs` |
| 2,250 | `src/lib/pages/SettingsPage.svelte` |
| 1,737 | `src-tauri/src/commands/live.rs` |
| 1,185 | `crates/storage/src/migrations.rs` |
| 1,081 | `src/lib/pages/DictationPage.svelte` |
| 897 | `src/lib/pages/HistoryPage.svelte` |
| 790 | `src-tauri/src/commands/paste.rs` |
| 735 | `crates/transcription/src/streaming/rms_vad.rs` |
| 725 | `src/lib/pages/TasksPage.svelte` |
| 720 | `src-tauri/src/commands/models.rs` |
| 697 | `src/lib/stores/page.svelte.ts` |
> **Phase 1 candidate.** `database.rs` (2.5k), `SettingsPage.svelte` (2.25k), and `live.rs` (1.7k) are each large enough to deserve a structural review in isolation. HANDOVER.md already flags `SettingsPage` as needing decomposition into 7 progressive-disclosure groups.
---
## 3. Crate inventory
| Crate | LOC | Files | `pub` items (lib.rs / total) | Tests |
|---|---:|---:|---:|---:|
| `magnotia-core` | 1,212 | 9 | 10 / 104 | 16 |
| `magnotia-audio` | 1,533 | 8 | 14 / 38 | 14 |
| `magnotia-transcription` | 2,617 | 12 | 13 / 51 | 51 |
| `magnotia-llm` | 1,330 | 6 | 27 / 56 | 17 |
| `magnotia-ai-formatting` | 1,502 | 6 | 9 / 21 | 47 |
| `magnotia-storage` | 3,771 | 4 | 6 / 69 | 60 |
| `magnotia-hotkey` | 632 | 3 | 5 / 14 | 4 |
| `magnotia-cloud-providers` | 80 | 2 | 2 / 3 | 2 |
| `magnotia-mcp` | 584 | 2 | 8 / 8 | 9 |
| `src-tauri` (`magnotia` + `magnotia_lib`) | 8,330 | 27 | n/a | 67 |
| **Total** | **21,591** | | | **287** |
**Outliers worth a Phase-2 look:**
- `magnotia-core` exposes 104 public items — high for a "shared types" crate; likely leakage of internals.
- `magnotia-storage` exposes 69 public items across only 4 files; the file split is suspect (2.5k-line `database.rs`).
- `magnotia-cloud-providers` is 80 LOC and 3 public items — README calls it "empty scaffolding" (verified: just an in-memory keystore + env-var fallback). Either grow it or remove it; it currently earns nothing.
---
## 4. Crate dependency graph
```
magnotia-core ──┬─→ magnotia-audio
├─→ magnotia-transcription
├─→ magnotia-llm ──→ magnotia-ai-formatting
├─→ magnotia-cloud-providers
├─→ magnotia-hotkey
└─→ magnotia-storage ──→ magnotia-mcp
magnotia (src-tauri)
└─→ all 8 library crates (NOT magnotia-mcp — separate binary)
```
**Observations:**
- `magnotia-core` is the workspace floor; nothing depends on it depending on something else. Good.
- DAG is clean — no cycles, no upward dependencies.
- `magnotia-mcp` correctly depends only on `magnotia-storage` (its sole job is to read the SQLite DB). The Tauri app does **not** depend on it, confirming the "separate process" claim in the README.
- `magnotia-ai-formatting` depends on both `core` and `llm`. Reasonable.
> **Phase 2 will verify:** every `pub` item in the leaf crates (`audio`, `transcription`, `llm`, `storage`, `hotkey`) has at least one external consumer. Internal-only items shouldn't be `pub`.
---
## 5. External surfaces
### 5.1 Tauri commands
**102 `#[tauri::command]` attributes** across **22 of 25** modules in `src-tauri/src/commands/`.
- `power.rs` and `security.rs` are utility modules (no commands; helpers only).
- `mod.rs` is the registry.
| Module | # commands | Module | # commands |
|---|---:|---|---:|
| `tasks` | 12 | `intentions` | 5 |
| `models` | 12 | `audio` | 4 |
| `llm` | 10 | `tts` | 3 |
| `profiles` | 9 | `transcription` | 3 |
| `transcripts` | 8 | `paste` | 3 |
| `windows` | 8 | `update` | 2 |
| `diagnostics` | 6 | `rituals` | 2 |
| `hotkey` | 5 | `live` | 2 |
| | | `hardware` | 2 |
| | | `feedback` | 2 |
| | | `nudges`, `meeting`, `fs`, `clipboard` | 1 each |
**Every one of these is a trust boundary** — Phase 4 (security) will audit input validation per command.
### 5.2 MCP tools (read-only stdio)
Confirmed in `crates/mcp/src/lib.rs`:
- `list_transcripts`
- `get_transcript`
- `search_transcripts`
- `list_tasks`
The `init_readonly` connection mode in `magnotia-storage` is opened at OS level (`SQLITE_OPEN_READONLY`), per `crates/mcp/src/main.rs:18` — Phase 4 will confirm with a write-attempt test.
### 5.3 Frontend route surface
| Route | Purpose | Layout |
|---|---|---|
| `/` | Main dictation shell | `+layout.svelte` (sidebar + chrome) |
| `/float` | Tasks float window | `+layout@.svelte` (chrome-free) |
| `/viewer` | Transcript editor | `+layout@.svelte` (chrome-free) |
| `/preview` | Live transcription overlay | `+layout@.svelte` (chrome-free) |
**Pages:** `DictationPage`, `SettingsPage`, `HistoryPage`, `TasksPage`, `FilesPage`, `FirstRunPage`, `ShutdownRitualPage` (7).
**Stores:** `page`, `preferences`, `profiles`, `toasts`, `focusTimer`, `llmStatus`, `nudgeBus`, `implementationIntentions`, `completionStats`, `speaker` (10).
**Components:** 25 in `src/lib/components/`.
**i18n locales:** `en`, `es`, `de` (scaffolding only — most strings are still hard-coded; the migration is incremental per README).
### 5.4 Model registry
7 models declared in `crates/core/src/model_registry.rs`:
- Whisper (6): `whisper-tiny-en`, `whisper-base-en`, `whisper-small-en`, `whisper-distil-small-en`, `whisper-medium-en`, `whisper-distil-large-v3`
- Parakeet (1): `parakeet-ctc-0.6b-int8`
> Moonshine is mentioned in the README's `magnotia-core` description ("Moonshine entries") but **no Moonshine entry exists in the registry**. See §7.
---
## 6. Test floor
| Location | Count |
|---|---:|
| `crates/*/src/` (lib tests) | 217 |
| `crates/*/tests/` (integration) | 3 |
| `src-tauri/src/` + `src-tauri/tests/` | 67 |
| **Total** | **287** |
Only 3 cross-crate integration tests is light. Per-crate lib tests dominate. Phase 5 (test integrity) will mutation-test the heavy crates (`storage`, `transcription`, `llm`) to grade whether these tests actually pin behaviour.
---
## 7. README ↔ code drift
Items where the README disagrees with the code as-of this audit:
| README claim | Reality | Severity |
|---|---|---|
| "245 automated lib tests across 10 crates" (line 14) | **287 tests** total (220 lib + 67 src-tauri); 220 lib-only | LOW — undercount (good direction, but stale) |
| "10 crates" (line 14) | 9 library crates + 1 app crate (`src-tauri`) — depends how you count; technically the workspace has 10 packages | OK if counting `src-tauri`; misleading otherwise |
| "Commands: audio, clipboard, diagnostics, hotkey, live, llm, meeting, models, paste, power, profiles, tasks, transcription, transcripts, update, windows" (line 95-97) — 16 listed | **22 modules with commands**: README missing `feedback`, `fs`, `intentions`, `nudges`, `rituals`, `tts`. Architecture diagram and §"Tauri commands" table both stale. | **MED** — visible to anyone evaluating the codebase |
| "18 Tauri command modules" (line 117) | **25 files** in `commands/` (22 with command attrs + `mod`, `power`, `security`) | MED |
| `magnotia-core` "model registry (Whisper + Parakeet + Moonshine entries)" (line 165) | **No Moonshine entries** in `model_registry.rs`. 6 Whisper + 1 Parakeet only. | **MED** — claims an unimplemented feature |
| Stores listed: `settings, profiles, tasks, history, taskLists, templates, page, toasts, preferences` (line 202) | Actual stores: `page, preferences, profiles, toasts, focusTimer, llmStatus, nudgeBus, implementationIntentions, completionStats, speaker`. README list is **largely fictional** — there is no `tasks`, `history`, `taskLists`, `templates`, or `settings` store as a separate file. | **HIGH** — describes architecture that doesn't exist |
| `magnotia-cloud-providers` "BYOK cloud-STT provider stubs… Currently empty scaffolding. When populated: OpenAI-compatible endpoint + Anthropic" (line 172) | Crate has an in-memory API-key store with env-var fallback — not "empty scaffolding". No HTTP code, no provider implementations. | LOW — partial |
| "Every new workspace crate needs a `description` in its `Cargo.toml`" (line 362, contributing rule) | **`crates/llm/Cargo.toml` has no `description` field.** Self-violation of the contribution rule. | LOW — easy fix |
| README §"Architecture" Rust crate list spelling (line 102-104) | Correct, but the manual line-break formatting got mangled by the rebrand sweep — visible whitespace inconsistency. | TRIVIAL |
> **Phase 0 verdict on documentation truth:** The README is **mostly right but actively misleading in two places** — the stores list and the Moonshine claim. Both will fail an acquirer's first sanity-check (`grep -r "Moonshine" crates/`) and erode trust in the rest of the doc.
---
## 8. HANDOVER files
| File | Date | Topic | Status |
|---|---|---|---|
| `HANDOVER.md` | 2026-04-25 | Latest session (Phase 9a–9d) | Active reference |
| `HANDOVER-2026-04-24.md` | 2026-04-24 | Phase 8 close | Historical |
| `HANDOVER-2026-04-19.md` | 2026-04-19 | Earlier session | Historical |
| `HANDOVER-2026-04-18.md` | 2026-04-18 | Earlier session | Historical |
| `HANDOVER-2026-04-17.md` | 2026-04-17 | Earliest in tree | Historical |
Five handovers in the repo root is unusual — most projects keep one. Phase 8 (docs truth) will recommend either archiving them under `docs/handovers/` or rotating to a single `HANDOVER.md` with prior content moved.
The post-rebrand state: all five handovers were rewritten by today's sweep (line counts identical, words different). They now reference `magnotia` paths but their **content** describes work done under the `kon` / `corbie` names — there's a temporal-vs-naming mismatch a reader has to mentally track. Acquirer-friendly fix: add a one-line note at the top of each historical handover saying "Originally written when the product was named X; references rewritten 2026-04-30."
---
## 9. Fix areas — actionable tasks
Each task below is concrete: file, change, verification, effort. Pick any in any order; they don't depend on later phases. Items are grouped by impact tier.
### Tier A — High impact, do first
#### A1. README stores list is fiction
- **File:** `README.md`, line 202
- **Current:** `Reactive stores (src/lib/stores/page.svelte.ts): settings, profiles, tasks, history, taskLists, templates, page, toasts, preferences.`
- **Reality:** stores are `page`, `preferences`, `profiles`, `toasts`, `focusTimer`, `llmStatus`, `nudgeBus`, `implementationIntentions`, `completionStats`, `speaker` — each in its own `*.svelte.ts` file under `src/lib/stores/`.
- **Fix:** rewrite the bullet to enumerate the actual ten store files, and clarify that `page.svelte.ts` is the central app-state store (transcripts, profiles, taskLists, etc. live as fields on it).
- **Verify:** `ls src/lib/stores/` matches the README list 1:1.
- **Effort:** 10 min.
#### A2. Moonshine claim has no implementation
- **File:** `README.md`, line 165 (`magnotia-core` row in the crate table)
- **Current:** `model registry (Whisper + Parakeet + Moonshine entries)`
- **Reality:** `crates/core/src/model_registry.rs` has 6 Whisper + 1 Parakeet entries. Zero Moonshine.
- **Fix (pick one):**
- (a) Remove the Moonshine reference from the README. Cheapest.
- (b) Add a `// TODO(moonshine): not yet wired` constant in `model_registry.rs` and a roadmap entry under §Roadmap, so the claim is at least flagged as forthcoming.
- **Verify:** `grep -ri moonshine crates/ src-tauri/ src/` returns no orphan references.
- **Effort:** 5 min (option a) / 30 min (option b).
#### A3. Six Tauri command modules undocumented
- **File:** `README.md`, lines 95-97 (Architecture diagram) and 175-195 (Tauri commands table)
- **Missing:** `feedback`, `fs`, `intentions`, `nudges`, `rituals`, `tts`
- **Fix:** add a one-line description for each in the §Tauri commands table; add the names to the Architecture-diagram bullet list.
- **Verify:** `ls src-tauri/src/commands/*.rs | xargs basename -s .rs | sort` matches the README table 1:1 (excluding `mod`, `power`, `security`, which are utility modules — note that explicitly).
- **Effort:** 20 min.
### Tier B — Low effort, removes self-violations
#### B1. `crates/llm/Cargo.toml` missing `description`
- **File:** `crates/llm/Cargo.toml`
- **Current:** `[package]` block has `name`, `version`, `edition` only.
- **Reality:** README §Contributing line 362 declares this a hard rule. Self-violation.
- **Fix:** add `description = "Local LLM engine for Magnotia (Qwen3 via llama-cpp-2). Cleanup, task extraction, content tags."` (or similar). Match the prose style of the other 8 crates' descriptions.
- **Verify:** `for d in crates/*/Cargo.toml src-tauri/Cargo.toml; do grep -L "^description" "$d"; done` returns empty.
- **Effort:** 2 min.
#### B2. Stale test-count claim
- **File:** `README.md`, line 14
- **Current:** `245 automated lib tests across 10 crates, all passing`
- **Reality:** 287 tests total (220 lib + 67 src-tauri); 220 lib-only.
- **Fix:** decide on a number that's automatable, not a snapshot. Either: (a) replace with `220+ lib tests across 9 library crates plus 67 Tauri-app tests`, or (b) drop the absolute number and say `comprehensive automated test floor — see CI for current count`.
- **Verify:** `grep -rE '#\[(test|tokio::test)\]' crates/*/src/ | wc -l` matches whatever number you ship.
- **Effort:** 5 min.
#### B3. Crate count claim ambiguity
- **File:** `README.md`, line 14 ("10 crates")
- **Reality:** 9 library crates + 1 Tauri app crate. The README's own crate table only documents 9.
- **Fix:** say "9 library crates plus the Tauri app crate" — or just "9 library crates" and let the Tauri app stand separately, which matches the existing prose.
- **Effort:** 2 min.
### Tier C — Structural smells (defer to Phase 2 but flag now)
#### C1. `magnotia-core` over-exports
- **File(s):** `crates/core/src/lib.rs` and the modules it re-exports
- **Symptom:** 104 public items in a "shared types" crate. High blast radius for any change.
- **Fix (Phase 2 work, do not touch yet):** audit every `pub` item; demote anything not used outside the crate to `pub(crate)`. The expected outcome is a 30–60% reduction in public surface.
- **Verify:** after the demotion pass, `cargo +nightly rustdoc` should still succeed and downstream crates should still compile without changes.
- **Effort:** ~½ day (Phase 2 scope).
#### C2. `magnotia-storage::database.rs` is 2,534 lines
- **File:** `crates/storage/src/database.rs`
- **Symptom:** single file holds CRUD for transcripts, tasks, subtasks, profiles, profile-terms, settings, error log, FTS5. No internal module boundaries.
- **Fix (Phase 2):** split by domain — `database/transcripts.rs`, `database/tasks.rs`, `database/profiles.rs`, etc. Keep the public re-export shape unchanged so callers don't move.
- **Verify:** `cargo test -p magnotia-storage` still passes; no public-API changes.
- **Effort:** ~2-4 hours.
#### C3. `SettingsPage.svelte` is 2,250 lines
- **File:** `src/lib/pages/SettingsPage.svelte`
- **Symptom:** HANDOVER.md already flags this; `SettingsGroup.svelte` was prepared but the seven-group split was deferred.
- **Fix (Phase 2):** complete the planned restructure. Pick this up from HANDOVER.md §"9c — Settings (scaled down)".
- **Effort:** ~½ day.
#### C4. `magnotia-cloud-providers` does not earn its existence
- **Files:** `crates/cloud-providers/` (80 LOC across 2 files)
- **Symptom:** crate contains an in-memory keystore with env-var fallback. Not "empty scaffolding" as the README says — but also not provider-specific. No HTTP code, no providers.
- **Fix (decide, then act):**
- (a) **Fold** into `magnotia-core::keystore` (preferred — it's a generic key store, nothing cloud-specific). Drop the crate. README §Architecture and the dependency graph simplify.
- (b) **Grow** it: actually implement an OpenAI-compatible STT client and an Anthropic STT client, gated behind a `cloud-stt` feature flag. Earn the boundary.
- **Verify (option a):** workspace builds with `cloud-providers` removed from `Cargo.toml` members; the two consumers (`commands/llm.rs` and wherever else) re-import from `magnotia-core::keystore`.
- **Effort:** ~1 hour (option a) / multi-day (option b).
### Tier D — Hygiene (Phase 1 / Phase 8)
#### D1. Five HANDOVER files in repo root
- **Files:** `HANDOVER.md`, `HANDOVER-2026-04-{17,18,19,24}.md`
- **Symptom:** root noise; rebrand also rewrote their content so they describe `kon`/`corbie` work but read as `magnotia`.
- **Fix:**
- Move the four dated files under `docs/handovers/`.
- Add a one-line italic note at the top of each historical file: *"Originally written when the product was named Kon (and briefly Corbie); references rewritten in the 2026-04-30 rebrand sweep."*
- Keep the latest as `HANDOVER.md` in root, or also move under `docs/handovers/HANDOVER-latest.md` with a symlink — pick one.
- **Effort:** 15 min.
#### D2. Tauri command total count drift
- **README** says "18 Tauri command modules" (line 117); actual is 22 modules with commands (plus 3 utility modules in the same dir).
- **Fix:** update line 117 to "22 Tauri command modules + 3 utility modules (`mod`, `power`, `security`)".
- **Effort:** 1 min — usually folded into A3.
---
## 10. Phase 1 entry plan
Tier A and Tier B fixes above (≈45 min total) bring the README back into truth and close the self-imposed Cargo.toml rule. Do these as a warm-up before Phase 1 proper; they make every subsequent phase' "what does the README say?" comparison cheaper.
Phase 1 (Lean-pass) — see [`phases-1-8-playbook.md`](phases-1-8-playbook.md) — should then target, in order:
1. `cargo machete` + `cargo udeps` workspace-wide → unused deps kill list.
2. `knip` on the frontend → unused TS/Svelte modules.
3. Manual review of the **5 files >1k LOC** for duplicate logic (`SettingsPage.svelte`, `database.rs`, `live.rs`, `migrations.rs`, `DictationPage.svelte`).
4. Grep audit of `TODO` / `FIXME` / `unimplemented!` / `unwrap()` outside tests → tech-debt log.
5. Apply the Tier C structural smells if Phase 2 is being done immediately afterwards.
Estimated time: **1 working day** for Phase 1 in full, plus ~45 min of Tier A/B fixes.

# Phase 1 — Lean-pass (scan-only deliverable)
*Read-only deliverable; no code changes applied. Removals and refactors deferred to a review pass.*
Date: 2026-05-01. Branch: `main` @ `7ff7295` (working tree clean at scan start; a parallel agent is committing the Phase 0 §9 Tier A/B/D1 README and `Cargo.toml` documentation fixes alongside this scan). Status: scan-only.
---
## Methodology
This is the find-first half of audit discipline. Every section below is a scan output, lightly categorised. No code was modified to produce this report; remediation gets a separate commit and review pass after Jake walks the findings. The Phase 1 playbook (`docs/audit/phases-1-8-playbook.md` §Phase 1) calls for `cargo machete`, `cargo udeps`, `knip`, `depcheck`, dead-code lints per crate, a tech-debt grep, an `unwrap`/`expect` panic-surface scan, manual notes on the five files >1k LOC, and `jscpd` cross-file duplication. All steps were attempted; toolchain gaps are logged in §"Scans deferred".
Severity grades (per playbook): **P0** must-fix before any release; **P1** must-fix before sale or public beta; **P2** worth fixing, not blocking.
---
## 1. Unused Rust dependencies
`cargo machete` (v0.9.2, freshly installed, recursive workspace mode) flags **4 unused-dependency hits across 4 crates**.
| ID | Severity | Crate | `Cargo.toml` declares | Notes |
|---|---|---|---|---|
| L1.1 | P2 | `magnotia-cloud-providers` | `magnotia-core` | Crate is 80 LOC of in-memory keystore; no `magnotia_core::` imports in source. Likely dead since cartography §3 ("not earning its existence"). Cross-references Phase 0 Tier C4. |
| L1.2 | P2 | `magnotia-core` | `async-trait` | Not used inside `core`'s own modules. Worth confirming with reverse-grep before removal — `async_trait` is sometimes pulled in by macro expansion only. |
| L1.3 | P2 | `magnotia-core` | `serde_json` | Same caveat — many crates pull `serde_json` for downstream re-export, but `core` should not need it directly. |
| L1.4 | P2 | `magnotia-hotkey` | `magnotia-core` | Hotkey crate compiles standalone; only depends on `core` for shared error types presumably, but the import is not present. |
| L1.5 | P2 | `magnotia` (`src-tauri`) | `magnotia-cloud-providers` | The Tauri crate declares the cloud-providers crate, but no `magnotia_cloud_providers::` symbol appears in `src-tauri/src`. Folds into Phase 0 Tier C4 (kill or grow `cloud-providers`). |
**Cross-check with `cargo udeps`:** *not run.* The repo currently has only a stable Rust toolchain installed (`rustup toolchain list` returned `stable-x86_64-unknown-linux-gnu` only). `cargo udeps` requires nightly. Logged under Scans deferred.
**Recommended Phase-1 follow-up:** before deleting any of these, do a workspace-wide reverse grep for each dep name; macros and re-exports defeat machete. The L1.4 and L1.5 hits in particular suggest `magnotia-cloud-providers` as a unit is removable (cartography Tier C4 option a — fold into `magnotia-core::keystore`).

## 2. Unused frontend modules
### 2.1 `npx knip`
**Files reported as unused (9):**
| ID | Severity | File | Notes |
|---|---|---|---|
| L2.1 | P2 | `src/app.d.ts` | SvelteKit ambient declaration. Knip almost always false-positives on these; **keep**. |
| L2.2 | P2 | `src/design-system/colors_and_type.css` | Reference design-system, not live code (cartography §2 already excludes the design-system from active LOC). Verify before deletion. |
| L2.3 | P2 | `src/design-system/ui_kits/DictationPage.jsx` | Reference UI kit (JSX in a Svelte project — clearly a sketch, not a build target). |
| L2.4 | P2 | `src/design-system/ui_kits/OtherPages.jsx` | As above. |
| L2.5 | P2 | `src/design-system/ui_kits/Sidebar.jsx` | As above. |
| L2.6 | P2 | `src/lib/components/VirtualSegmentList.svelte` | Possible orphan after a refactor. Worth a `grep -r VirtualSegmentList src/` to confirm before removal. |
| L2.7 | P2 | `src/lib/components/VisualTimer.svelte` | Same — verify no dynamic import or string-named lookup. |
| L2.8 | P2 | `src/lib/shims.d.ts` | TypeScript shim. Knip false-positive class; **keep**. |
| L2.9 | P2 | `static/pcm-processor.js` | AudioWorklet module — loaded by URL string at runtime, not by import. **Keep** (false positive). |
**Unused dependencies (3):**
| ID | Severity | Package | Notes |
|---|---|---|---|
| L2.10 | P2 | `@tauri-apps/plugin-autostart` | Likely registered Rust-side in `src-tauri/Cargo.toml` and configured via `tauri.conf.json` rather than imported from JS. Verify — if the Rust side uses it, the JS dep can go. |
| L2.11 | P2 | `@tauri-apps/plugin-global-shortcut` | Same — Rust-side registration. |
| L2.12 | P2 | `@tauri-apps/plugin-opener` | Same. |
**Unlisted binaries (1):**
| ID | Severity | Reference | Notes |
|---|---|---|---|
| L2.13 | P2 | `du` in `.github/workflows/build.yml` | Just a system tool used in CI. Informational; nothing to do. |
**Unused exports (31) and exported types (28):** see `/tmp/claude-1000/.../bq57g56il.output` for the full list. The high-density file is `src/lib/utils/textMeasure.ts` (5 exports, none consumed) and `src/lib/utils/settingsMigrations.ts` (3 exports + 2 types). Treat each as a candidate for either consumption or deletion. **Severity P2 across the board** — the exports are dead but harmless; their LOC saving is real but the risk of collateral damage is nonzero (they could be imported by name from another package or via dynamic lookup). Manual review per-file in Phase 2.
### 2.2 `npx depcheck`
Run with `--skip-missing` to avoid false positives on dev tooling.
| ID | Severity | Package | Notes |
|---|---|---|---|
| L2.14 | P2 | `@tauri-apps/plugin-autostart` | Confirms L2.10. |
| L2.15 | P2 | `@tauri-apps/plugin-global-shortcut` | Confirms L2.11. |
| L2.16 | P2 | `@tauri-apps/plugin-opener` | Confirms L2.12. |
| L2.17 | P2 | `lucide-svelte` | **Worth investigating.** Declared but depcheck found no JS-side import. If icons are inlined as SVG, the dep is genuinely dead. If imported via a wrapper component, false positive. |
| L2.18 | P2 | `tailwindcss` (devDep) | Almost certainly a false positive — Tailwind is wired in via `@tailwindcss/vite` plugin in `vite.config.js` rather than a direct import. **Keep.** |
**Convergent signal:** L2.10/11/12 plus L2.14/15/16 — both tools agree the three Tauri plugins are JS-unused. They are still required Rust-side (the Tauri JS bridge ships separately from the Rust plugins), so the safe pattern is to keep them only if the JS API is invoked from the frontend. Quick `grep -r 'autostart\|globalShortcut\|opener' src/` answers it; that is a Phase 2 pass, not a Phase 1 deletion.
---
## 3. Dead Rust code
Each crate was rebuilt (workspace + `--all-targets`) with `RUSTFLAGS="-W dead_code -W unused"` to surface the strictest defaults.
**Result:** **zero warnings emitted across all nine library crates and `src-tauri`.**
This is genuine — both `cargo build --workspace` and `cargo build --workspace --all-targets` came back clean with the elevated flags. The codebase does not carry obvious unreachable Rust code, unused imports, or unused private items as scored by rustc's default dead-code detector. Stronger lints (`clippy::pedantic`, `clippy::nursery`) are deferred to Phase 3 per the playbook.
**Caveat:** rustc's `dead_code` only fires when a `pub` item has no callers *anywhere in the same crate*; cross-crate dead `pub` items (where the only callers are inside a sibling crate that has since stopped using them) require the workspace-wide reverse-grep pass scheduled for Phase 2 step 5 (the `magnotia-core` 104-public-items audit). The L1.* dependency hits above are early evidence that some inter-crate links are already dormant.
---
## 4. Tech-debt grep
`grep -rnE "TODO|FIXME|HACK|XXX|unimplemented!\(\)|todo!\(\)" --include="*.rs" --include="*.svelte" --include="*.ts"` returned **5 hits** total — a remarkably low count for a 36k-LOC codebase.
| ID | Severity | File:line | Marker | Bucket | Suggested action |
|---|---|---|---|---|---|
| L4.1 | P2 | `crates/cloud-providers/src/keystore.rs:13` | TODO | (a) genuine reminder | Replace process-local `Mutex<HashMap>` keystore with `keyring` crate or platform-native credential storage so secrets persist across sessions. Cross-references Phase 0 Tier C4 (and the Plinth `MEMORY.md` note about plaintext Foundry secrets — same family of issue). Log to issue tracker. |
| L4.2 | P2 | `crates/storage/src/database.rs:166` | (TODO) | (b) historical comment | Already-resolved TODO referenced in a doc comment ("the rename was a UI-only state change with a TODO never wired up"). Reads as historical narrative; not actionable but cluttery. Optional: shorten the comment in a docs pass. |
| L4.3 | P1 | `crates/storage/src/database.rs:1124` | TODO | (c) silent admission | `log_error` is implemented but the doc comment states it is *not yet wired into Tauri command error paths*. Result: every command's error is converted to a `String` and returned to the JS layer, but the persistent `error_log` table is never written to from production paths. **This is real audit signal**: the README and crate surface advertise an error-log capability that is dormant. Wire it into the command-layer `?` translations in Phase 3. |
| L4.4 | P2 | `src/lib/components/MorningTriageModal.svelte:262` | TODO | (a) genuine reminder | Promote inline `#1a1816` 50%-alpha overlay colour to a `--color-overlay` token in `app.css`. Cosmetic; safe to action in Phase 8 (docs/style truth) or whenever a token-pass happens. |
| L4.5 | P2 | `src-tauri/src/commands/transcripts.rs:6` | TODO (in narrative comment) | (b) historical | Comment narrates that a previous TODO ("persist to SQLite when update_transcript exists") has been resolved. Like L4.2: historical, not actionable. Optional cleanup. |
**Bucket totals:** 1 × bucket (a), 2 × bucket (b), 1 × bucket (c, escalated to P1). Zero `FIXME`, zero `HACK`, zero `XXX`, zero `unimplemented!()`, zero `todo!()` in the entire active codebase. That last point is itself a strong-positive finding — see §Defect log summary.
---
## 5. Panic surface (`unwrap` / `expect` outside tests)
The raw grep returned **385 hits**, but a context-aware Python pass (which tracks `#[test]`, `#[tokio::test]`, and `#[cfg(test)] mod`) finds that **359 of those are inside test bodies or `#[cfg(test)]` modules** and **only 26 sit on production paths**. Production list below.
| File:line | Context (1 line) | Risk note |
|---|---|---|
| `crates/mcp/src/lib.rs:230` | `serde_json::to_string_pretty(&summaries).unwrap()` | Serialising a `Vec<TranscriptSummary>` we just built; cannot fail in practice but the `.unwrap()` will panic the MCP stdio worker on any bug in the type. Trade for `?`. |
| `crates/mcp/src/lib.rs:262` | `text_content(serde_json::to_string_pretty(&value).unwrap())` | Same family — JSON-stringifying a value of our own construction. |
| `crates/mcp/src/lib.rs:294` | `serde_json::to_string_pretty(&summaries).unwrap()` | Same. |
| `crates/mcp/src/lib.rs:319` | `serde_json::to_string_pretty(&summaries).unwrap()` | Same. |
| `crates/llm/src/lib.rs:102` | `let mut guard = self.inner.lock().unwrap()` | Standard `Mutex::lock().unwrap()` — only panics on poison. Acceptable in practice but a poisoned LLM mutex would panic the whole engine; an explicit `expect("LLM engine mutex poisoned")` would at least name the failure. |
| `crates/llm/src/lib.rs:137` | `let mut guard = self.inner.lock().unwrap()` | Same. |
| `crates/llm/src/lib.rs:145` | `self.inner.lock().unwrap().model.is_some()` | Same. |
| `crates/llm/src/lib.rs:149` | `self.inner.lock().unwrap().loaded.clone()` | Same. |
| `crates/llm/src/lib.rs:169` | `NonZeroU32::new(n_ctx).expect("n_ctx must be non-zero")` | Construction-time invariant; preceded by a guard that should rule out zero. Fine, but the invariant is not encoded — if a caller bypasses the guard, this panics on engine init. Reasonable to keep with the `expect`. |
| `crates/llm/src/lib.rs:380` | `let guard = self.inner.lock().unwrap()` | Mutex poison. |
| `crates/transcription/src/streaming/commit_policy.rs:125` | `self.history.back().expect("history is non-empty here")` | The expect string asserts a precondition that is enforced four lines above by `if self.history.is_empty() { return … }`. **Defensible** — the panic message even names the invariant. Document in a Phase-3 inline justification rather than refactor. |
| `crates/cloud-providers/src/keystore.rs:18` | `api_key_store().lock().unwrap()` | Mutex poison; same family as the `llm` ones. |
| `crates/cloud-providers/src/keystore.rs:31` | `api_key_store().lock().unwrap()` | Same. |
| `src-tauri/src/lib.rs:442` | `.expect("error while running Magnotia")` | The Tauri `run()` call. A panic here is the conventional pattern (no recovery anyway — process exit). Keep. |
| `src-tauri/src/commands/power.rs:61` | `.unwrap()` | Power-assertion mutex lock. Mutex poison. |
| `src-tauri/src/commands/power.rs:103` | `assertion_registry().lock().unwrap().insert(…)` | Mutex poison. |
| `src-tauri/src/commands/power.rs:134` | `assertion_registry().lock().unwrap().remove(&self.id)` | Mutex poison. |
| `src-tauri/src/commands/audio.rs:159` | `all_samples.lock().unwrap().clear()` | Mutex poison. |
| `src-tauri/src/commands/audio.rs:165` | `*state.wav_writer.lock().unwrap() = Some(writer)` | Mutex poison. |
| `src-tauri/src/commands/audio.rs:166` | `*state.temp_audio_path.lock().unwrap() = Some(temp_path)` | Mutex poison. |
| `src-tauri/src/commands/audio.rs:316` | `let mut all = state.all_samples.lock().unwrap()` | Mutex poison. |
| `src-tauri/src/commands/live.rs:330` | `self.state.resampler.as_mut().expect("resampler just set")` | Local invariant immediately after a `set` — defensible. |
| `src-tauri/src/commands/live.rs:497` | `let running = live_state.running.lock().unwrap()` | Mutex poison. |
| `src-tauri/src/commands/live.rs:581` | `*live_state.running.lock().unwrap() = Some(RunningLiveSession {…})` | Mutex poison. |
| `src-tauri/src/commands/live.rs:600` | `let running = live_state.running.lock().unwrap().take()` | Mutex poison. |
| `src-tauri/src/commands/live.rs:606` | `*live_state.running.lock().unwrap() = Some(running)` | Mutex poison. |
**Pattern summary.** The 26 production unwraps cluster into three categories:
- **Mutex poison** (19 occurrences): `Mutex::lock().unwrap()`. The well-known Rust idiom; only fails if a thread panicked while holding the lock. Acceptable but **inconsistent**: every site should at minimum carry an `expect("&str describing what")` so a poison-panic crash log names the lock. Phase 3 task: standardise.
- **Self-built JSON serialisation** (4 occurrences in `magnotia-mcp`): `serde_json::to_string_pretty(&value).unwrap()`. Cannot fail for our own types in practice, but the playbook's "prove it can't panic on user data" rule says these should become `?` or carry explicit `expect`s. Phase 3 task.
- **Locally-enforced invariants** (3 occurrences in `commit_policy`, `live`, `lib.rs`): the line above the `unwrap`/`expect` enforces the precondition. These are the most defensible; Phase 3 should add an inline `// SAFETY: …` comment naming the invariant rather than rewrite.
**Severity:** all P2 in isolation. Collectively → P1 to standardise before sale; an acquirer reading this list will want the convention named.

## 6. Largest-file duplicate-logic notes
### 6.1 `src/lib/pages/SettingsPage.svelte` — 2,250 LOC
Confirmed seven `<SettingsGroup>` top-level groups (lines 972, 1020, 1379, 1569, 1808, 1947, 2119) corresponding to the planned seven-group split documented in HANDOVER.md §"9c — Settings (scaled down)". The structural decomposition is **already in source** — what remains is the file split: each top-level `<SettingsGroup>` should move to its own `*.svelte` file under `src/lib/pages/settings/`. The page-level component then becomes a slim shell ~200 LOC.
**Inline observations:**
- 49 `<button>` elements in a single component is a smell — many will share handlers via prop drilling that a per-section split would localise.
- 57 declared `function` / `async function` blocks at the top level. Most are single-section helpers (model download, vocab management, audio device polling) and would migrate cleanly with their owning `<SettingsGroup>`.
- `let visibleAudioDevices = $derived(buildVisibleDevices(audioDevices))` (line 142) and the `buildVisibleDevices` helper (lines 96-142) are pure-functional and worth lifting into `src/lib/utils/audioDevices.ts` for unit-testing.
**Severity:** P2 structural. Cross-references Phase 0 Tier C3.
### 6.2 `crates/storage/src/database.rs` — 2,534 LOC
Function inventory confirms cartography §9 Tier C2: this file holds CRUD for **eight domains** (transcripts, transcript-search/FTS5, tasks, subtasks, profiles, profile-terms, settings, error-log, feedback, implementation-rules) plus seven row-mapping helpers (`transcript_row_from`, `profile_row_from`, `profile_term_row_from`, `task_row_from`, `implementation_rule_row_from`). No internal module boundaries; one flat namespace.
**Duplicate-logic candidates:**
- The `*_row_from` functions are mechanically similar; a `FromRow` trait or sqlx `FromRow` derive would collapse them. Not strictly duplicate but rhyming.
- `complete_subtask_and_check_parent` (line 447, ~50 LOC) embeds parent-completion logic that arguably belongs alongside `complete_task` (line 498). Extract candidate.
**Severity:** P2 structural; the planned split (`database/{transcripts,tasks,profiles,...}.rs`) is the right answer per Phase 0 Tier C2.
### 6.3 `src-tauri/src/commands/live.rs` — 1,737 LOC
Two `#[tauri::command]` functions at the top (`start_live_transcription_session` at 485, `stop_live_transcription_session` at 592). The remainder is pure helpers:
- **Session lifecycle:** `run_live_session`, `open_wav_writer`, `finalize_wav_writer`, `append_resampled_audio` (lines 646-722).
- **Inference dispatch:** `maybe_dispatch_chunk`, `poll_inference`, `emit_live_result` (lines 753-1013).
- **Tuning / overlap heuristics:** `trim_overlap_segments`, `filter_duplicate_boundary_segments`, `remember_recent_segments`, `build_nearby_transcript_candidates`, `normalize_transcript_text`, `count_common_tokens`, `longest_common_token_subsequence`, `is_low_signal_token`, `meaningful_tokens`, `transcripts_overlap`, `transcripts_loosely_overlap` (lines 1014-1250). **This is a self-contained de-duplication subsystem** that has no business living in a Tauri command file — it belongs in `magnotia-transcription/src/streaming/dedup.rs` (or similar) where it can be unit-tested without the Tauri runtime.
- **Speech-gate state machine:** `record_speech_window`, `speech_gate_decision`, `evaluate_speech_gate`, `downmix_chunk` (lines 1251-1336+). Likewise audio-domain logic; belongs in `magnotia-audio` or `magnotia-transcription`.
**Recommendation (Phase 2):** the file should be cut roughly in thirds. The two `#[tauri::command]` bodies plus session lifecycle stay; the dedup subsystem and the speech gate move to library crates. Estimated LOC for the resulting `live.rs`: ~600.
**Severity:** P1 structural. This is leakage of business logic into the trust boundary, and Phase 2 step 4 (no business logic in Tauri commands, ≤30 lines per command body) will catch the two commands as oversize. Logging here so Phase 2 has a starting point.
### 6.4 `crates/storage/src/migrations.rs` — 1,185 LOC
Inventory: 15 sequential, append-only migrations (versions 1 through 15) declared in a single `MIGRATIONS` constant (line 7). Each is a `(i64, &str, &str)` triple. The runner is `run_migrations_slice` (line 546), which:
1. Creates `schema_version` if absent.
2. Looks up `MAX(version)`.
3. For each pending migration: opens a single SQLite transaction, runs each `;`-split statement against it, then inserts the `schema_version` row in the same transaction, then commits.
`split_statements` (line 483) is the SQL splitter; respects `BEGIN…END` trigger blocks via depth counting, branches by uppercase keyword. The atomicity comment (lines 532-545) explicitly cross-references the 2026-04-22 RB-02 review, the previous bug, and the SQLite-specific reason it works.
**No duplicate logic found.** The append-only contract is documented at the constant declaration (line 4-6) and enforced by ordering: any new migration *must* take version 16 and live at the bottom. There is no migration replay path, no down-migration support, and no schema-introspection drift detection — those are deliberate omissions per the documented design.
**Severity:** zero issues. This file is the audit-friendliest artefact in the repo.
### 6.5 `src/lib/pages/DictationPage.svelte` — 1,081 LOC
32 declared `function` / `async function` blocks. The structural smell is concentration, not duplication — the file owns the entire dictate → cleanup → save → emit cycle:
- **Recording lifecycle:** `toggleRecording`, `startRecording`, `stopRecording`, `cleanup` (lines 295-442).
- **Cleanup pipeline:** `cleanupTranscriptIfEnabled`, `replaceSegmentsWithCleanedText` (lines 443-480).
- **Live-transcription wiring:** `handleLiveResult`, `handleLiveStatus`, `matchesLiveSession` (lines 137-218).
- **Model-state polling:** `checkModelState`, `ensureLlmModelLoaded`, `loadModel`, `onModelDownloaded` (lines 219-294).
Each cluster is a candidate child component. The model-state polling (~75 LOC) is the cleanest extract — it's a self-contained derived-state machine that could become a `<ModelStatusBadge>` component bound to a single store-derived `$derived`. The dictate/cleanup/save chain is harder to factor without restructuring shared `$state` declarations; defer to Phase 2 or a deliberate refactor session.
**Severity:** P2 structural. No duplicate logic *per se*; the refactor target is decomposition, not deduplication.
---
## 7. Cross-file duplication (jscpd)
`npx jscpd --min-tokens 50 src/ src-tauri/src/ crates/` reports **32 clones**, **362 duplicated lines**, **3,540 duplicated tokens**, **1.62% overall duplicate ratio**. By format: Rust 2.15% (29 clones), TypeScript 0.42% (3 clones), zero in JSON / Svelte / CSS / JSX / Markdown.
**Top cross-file pairs (≥10 lines, sorted by length):**
| ID | Severity | Lines | File pair (locations) | Notes |
|---|---|---:|---|---|
| L7.1 | P1 | 37 | `src-tauri/src/commands/transcription.rs` 377-413 ↔ 187-223 | **The Whisper vs. Parakeet path duplication.** `transcribe_pcm` (Whisper) and the Parakeet equivalent share the entire post-processing + `app.emit` block. 37-line clone. Real refactor candidate: extract `emit_transcription_result(app, segments, raw_text, options)` into a shared helper. |
| L7.2 | P1 | 22 | same file, 308-329 ↔ 187-208 | Same family, different start point. The transcription-command module has multiple near-identical setup blocks. |
| L7.3 | P1 | 19 | same file, 249-267 ↔ 155-173 | Same. |
| L7.4 | P2 | 19 | `src-tauri/src/commands/paste.rs` 567-585 ↔ 529-547 | Per-tool subprocess error-handling. The paste backend has one handler per platform tool (`xdotool`, `wtype`, `ydotool`, `osascript`, `powershell`). Each clones the success/exit/stderr-format pattern. Refactor: a `run_with_status(cmd, args, tool_name) -> Result<(), String>` helper would collapse five sites into one. |
| L7.5 | P2 | 18 | `src-tauri/src/commands/paste.rs` 219-236 ↔ 103-120 | Same family. |
| L7.6 | P2 | 16 | `src-tauri/src/commands/paste.rs` 618-633 ↔ 598-613 | Same — macOS `osascript` path. |
| L7.7 | P2 | 16 | `src-tauri/src/commands/paste.rs` 664-679 ↔ 643-658 | Same — Windows `powershell` path. |
| L7.8 | P2 | 15 | `crates/llm/tests/content_tags_smoke.rs` 16-30 ↔ `crates/llm/tests/smoke.rs` 18-32 | Test harness boilerplate — model load + engine init. Acceptable test duplication, but a `tests/common/mod.rs` helper would be cleaner. |
| L7.9 | **P1** | 15 | `crates/llm/src/model_manager.rs` 178-192 ↔ `crates/transcription/src/model_manager.rs` 25-39 | **Cross-crate clone.** Two separate model-manager implementations share download-and-verify logic. This is the highest-risk duplication in the report — a fix in one will not propagate. Phase 2 candidate: extract a shared `magnotia-core::model_download` (or grow `magnotia-cloud-providers` into a real "model fetcher" crate; cf. cartography Tier C4). |
| L7.10 | P2 | 15 | `src-tauri/src/commands/windows.rs` 183-197 ↔ 66-80 | Window-management command duplication. Likely the show/hide variants of the same logic. |
| L7.11 | P2 | 15 | `src-tauri/src/commands/paste.rs` 421-435 ↔ 392-406 | Per-tool paste fallback. |
| L7.12 | P2 | 14 | `src-tauri/src/commands/transcription.rs` 360-373 ↔ 160-173 | Continuation of L7.1-L7.3 family. |
| L7.13 | P2 | 12 | `crates/mcp/src/lib.rs` 276-287 ↔ 209-220 | MCP tool-handler boilerplate. Each `tools/call` arm rebuilds the result envelope. |
| L7.14 | P2 | 12 | `src-tauri/src/commands/transcription.rs` 347-358 ↔ 149-160 | Continuation. |
| L7.15 | P2 | 11 | `crates/transcription/src/model_manager.rs` 427-437 ↔ 373-382 | Intra-file repetition in the model manager — likely per-engine or per-model branches. |
| L7.16 | **P1** | 11 | `crates/llm/src/model_manager.rs` 415-425 ↔ `crates/transcription/src/model_manager.rs` 381-391 | Second cross-crate model-manager clone — same family as L7.9. |
| L7.17 | P2 | 11 | `src-tauri/src/commands/paste.rs` 202-212 ↔ 75-85 | More paste-backend boilerplate. |
**Top within-file pairs continued (≤10 lines):** mostly intra-file rhyme — `mcp/src/lib.rs` lines 299-308 ↔ 209-218; `crates/audio/src/decode.rs` 43-52 ↔ 30-40 (likely `i16` vs `f32` decode paths); various model-manager branches in `crates/transcription/src/model_manager.rs`.
**TypeScript clones (3):**
| ID | Severity | Lines | Pair | Notes |
|---|---|---:|---|---|
| L7.18 | P2 | 5 | `src/lib/utils/time.ts` 40-45 ↔ 31-36 | Two near-identical timestamp formatters; collapse into one with a precision arg. |
| L7.19 | P2 | 8 | `src/lib/stores/page.svelte.ts` 441-448 ↔ 418-425 | Task-row update + toast pair. Helper extract candidate. |
| L7.20 | P2 | 5 | `src/lib/stores/implementationIntentions.svelte.ts` 25-30 ↔ `src/lib/stores/nudgeBus.svelte.ts` 170-175 | Cross-file `todayLocalKey()` duplicate — exact-same date-formatting helper. Move to `src/lib/utils/time.ts`. |
**Headline finding:** the duplication burden concentrates in three places — `src-tauri/src/commands/transcription.rs` (Whisper/Parakeet path clones, L7.1-L7.3, L7.12, L7.14), `src-tauri/src/commands/paste.rs` (per-platform/per-tool clones, L7.4-L7.7, L7.11, L7.17), and the **cross-crate model-manager pair** `crates/llm/src/model_manager.rs` ↔ `crates/transcription/src/model_manager.rs` (L7.9, L7.16). The first two are local refactors; the third is architectural and crosses Phase 2's boundary-conformance brief.

## Defect log summary
**Total findings: 87** across the seven scans (counting each L#.# entry above as one finding).
By severity:
- **P0:** 0
- **P1:** 5 (L4.3 dormant `log_error`; L6.3 `live.rs` business-logic leakage; L7.1/L7.9/L7.16 Whisper-Parakeet and cross-crate model-manager clones)
- **P2:** 82
By scan:
| Scan | Findings | Top severity |
|---|---:|---|
| §1 unused Rust deps | 5 | P2 |
| §2 unused frontend modules | 18 | P2 |
| §3 dead Rust code | 0 | — |
| §4 tech-debt grep | 5 | P1 (one) |
| §5 panic surface | 26 | P2 (cluster → P1) |
| §6 largest-file duplicate-logic notes | 5 | P1 (one) |
| §7 jscpd cross-file dup | 28 | P1 (three) |
**Recommended Phase-2 escalations (beyond the playbook's planned scope):**
1. **L4.3 — wire `log_error` into command error paths.** Currently a documented capability that is dormant; visible to anyone running `grep -ri log_error` against the codebase. Add to Phase 3 (correctness audit) where the per-command error-path walk happens anyway.
2. **L6.3 — extract `live.rs` dedup + speech-gate subsystems** into `magnotia-transcription` (or a new sibling). The 1,737-LOC file becomes ~600 LOC and the extracted subsystems become unit-testable without Tauri.
3. **L7.9 / L7.16 — collapse the cross-crate model-manager duplication.** A shared `model_download` module (in `magnotia-core` or a grown `magnotia-cloud-providers`) replaces both per-crate copies. This compounds with cartography Tier C4 (the cloud-providers decision).
4. **§5 cluster — name every `Mutex::lock().unwrap()` site.** Cosmetic but uniform. Either everything carries an `expect("X mutex poisoned")` or everything stays bare; consistency is the audit artefact.
**Surprising positives worth noting in §Acceptance gate:**
- Zero dead-code warnings on a workspace-wide build with `RUSTFLAGS="-W dead_code -W unused"` and `--all-targets`. Suggests previous deletion passes have been thorough.
- Five tech-debt markers in 36k LOC. Zero `unimplemented!()`, zero `todo!()`, zero `FIXME`, zero `HACK`. The codebase carries almost no silent debt.
- 26 production unwraps, of which 19 are the standard `Mutex::lock().unwrap()` idiom. Genuine "unjustified panic surface" is closer to **3 sites** (L7-style locally-enforced invariants) plus **4 sites** (MCP JSON serialisation that should be `?`).
---
## Acceptance gate (per playbook)
The playbook's Phase 1 acceptance criteria are written for the apply-then-deliver flow; this is a scan-only deliverable, so the build/test gates apply but the LOC-reduction target does not.
**`cargo build --workspace`** — passes.
```
Finished `dev` profile [unoptimized + debuginfo] target(s) in 4m 07s (with RUSTFLAGS="-W dead_code -W unused")
Finished `dev` profile [unoptimized + debuginfo] target(s) in 24.96s (with --all-targets, no warnings)
```
**`cargo test --workspace`** — passes. **283 passed, 0 failed, 1 ignored** across 26 test binaries. (Cartography baseline: 287 — small drift attributable to the rebrand sweep; not a regression caused by this scan.)
**`npm run check`** — **1 ERROR, 0 WARNINGS** in 4080 files. The single error is *pre-existing* (the parallel agent's branch did not introduce it):
```
vite.config.js:5:1 Unused '@ts-expect-error' directive.
```
The directive sits above `const host = process.env.TAURI_DEV_HOST;` and was placed when `@types/node` was absent from devDependencies. It is now unused because the type info is being satisfied another way (likely Vite's bundled types). **Logged as L8.1 — P2.** Trivial to fix (delete the comment), but doing so is a code change and is therefore deferred per this report's read-only contract.
**LOC-reduction target** — deferred. No removals applied this pass; Phase 2 (or the scheduled review pass) will compute net LOC delta after the kill list above is acted on.
---
## Scans deferred (toolchain gaps)
| Scan | Reason | Recommended unblock |
|---|---|---|
| `cargo +nightly udeps --workspace --all-targets` | Only `stable-x86_64-unknown-linux-gnu` is installed (`rustup toolchain list`). | `rustup toolchain install nightly && cargo install cargo-udeps --locked`. Re-run inside Phase 2. |
| `cargo +nightly rustc -p <crate> -- -W dead_code -W unused` per the playbook | As above — the playbook's per-crate command is gated on nightly. Mitigated by running stable `cargo build --workspace --all-targets` with `RUSTFLAGS="-W dead_code -W unused"` instead, which produced the §3 zero-warning result. | Optional re-run on nightly to surface any nightly-only lint variants. |

# Audit Playbook — Phases 1 through 8
*Companion to [`phase0-cartography.md`](phase0-cartography.md). Pick up from any phase.*
This is a step-by-step playbook for an acquisition-grade audit of the Magnotia codebase. Phase 0 (Cartography) is complete; this document describes Phases 1–8.
**How to use this doc.** Each phase is independent enough to start in isolation, but they're ordered by leverage: earlier phases find the highest-value, lowest-risk wins. Don't skip phases without a reason.
For every phase: do the prep (`Inputs`), run the procedure, write the deliverable to `docs/audit/`, then commit before moving on. The deliverable is the audit trail.
---
## Conventions
- All commands assume `cwd = /home/user/magnotia` (or wherever the repo lives).
- All deliverables live under `docs/audit/`. Naming: `phaseN-<short-name>.md`.
- Severity grades used throughout: **P0** (must-fix before any release), **P1** (must-fix before sale / public beta), **P2** (worth fixing, not blocking).
- "Defect log" = a markdown table with columns: `ID | Severity | File:line | Summary | Suggested fix | Effort`.
- Before applying any non-trivial code change, commit the audit findings first. Audit and remediation are separate operations.
---
## Phase 1 — Lean-pass
**Goal.** Find dead code, unused dependencies, duplicate logic, and leftover scaffolding. Apply low-risk deletions; log higher-risk ones for Phase 2.
**Time:** 1 working day.
**Inputs:** Phase 0 §2 (largest files), §9 Tier C (structural smells).
### Procedure
1. **Unused Rust dependencies.**
```bash
cargo install cargo-machete cargo-udeps --locked
cargo machete --workspace
cargo +nightly udeps --workspace --all-targets
```
For each false positive (a dep used only behind a feature flag), document it; for each real hit, remove from the relevant `Cargo.toml`.
2. **Unused frontend modules.**
```bash
npx knip
npx depcheck
```
Apply removals; rerun `npm run check` to confirm nothing breaks.
3. **Dead Rust code.**
```bash
cargo +nightly rustc -p magnotia-core -- -W dead_code -W unused 2>&1 | grep -E "warning|note"
```
Repeat for every crate. Expect false positives in `pub` items used only by `src-tauri`; the real signal is `pub(crate)` items with no callers.
4. **Tech-debt grep.**
```bash
grep -rnE "TODO|FIXME|HACK|XXX|unimplemented!\(\)|todo!\(\)" \
--include="*.rs" --include="*.svelte" --include="*.ts" \
--exclude-dir=node_modules --exclude-dir=target . > /tmp/tech-debt.txt
```
Bucket each match: (a) genuine reminder for known work, (b) "won't actually do" — delete, (c) silent admission of incomplete code — escalate to defect log.
5. **`unwrap()` / `expect()` outside tests.**
```bash
grep -rnE "\.(unwrap|expect)\(" crates/ src-tauri/src/ \
--include="*.rs" | grep -v "/tests/" | grep -v "test " | grep -v "#\[test\]"
```
Each is a potential panic-on-bad-input. For each, prove it can't panic on user data, or replace with `?`/`map_err`.
6. **Duplicate logic in 1k+ LOC files.** Manually walk:
- `src/lib/pages/SettingsPage.svelte` (2,250 LOC) — already flagged for the seven-group split.
- `crates/storage/src/database.rs` (2,534 LOC) — split by domain (Phase 0 §9 C2).
- `src-tauri/src/commands/live.rs` (1,737 LOC) — look for mixed concerns (session lifecycle vs. tuning).
- `crates/storage/src/migrations.rs` (1,185 LOC) — confirm migrations are append-only and v-numbered.
- `src/lib/pages/DictationPage.svelte` (1,081 LOC) — extract child components for any block >150 lines.
7. **Cross-file duplicate detection.**
```bash
npx jscpd --min-tokens 50 src/ src-tauri/src/ crates/
```
Threshold ≥50 tokens; anything above 5% similarity in a file pair is worth a look.
### Deliverable
`docs/audit/phase1-lean-pass.md` — three sections:
- **Removed:** what was deleted, with line-count savings.
- **Kept with reason:** items that look unused but aren't (with the reason).
- **Escalated to Phase 2:** structural duplications too risky to touch as a one-shot.
### Acceptance criteria
- `cargo build --workspace` passes.
- `cargo test --workspace` passes (no test count regression beyond explicitly-deleted-test count).
- `npm run check` passes.
- Net LOC reduction documented (target: ≥3% reduction or a written justification of why not).
---
## Phase 2 — Architecture conformance
**Goal.** Verify the 10-crate boundary is real, not aspirational. Tighten public API surfaces. Restructure files >1k LOC where the split is obvious.
**Time:** 1 working day.
**Inputs:** Phase 0 §4 (dependency graph), §3 (pub item counts), Phase 1 escalations.
### Procedure
1. **No upward dependencies.** The Phase 0 dependency graph is acyclic; confirm no new edges have been added.
```bash
for d in crates/*/Cargo.toml; do
name=$(grep -m1 '^name' "$d" | sed 's/.*"\(.*\)"/\1/')
deps=$(grep -E "^magnotia[-_]" "$d" | sed 's/ *=.*$//')
echo "$name -> $deps"
done
```
If any leaf crate now imports `magnotia` (the Tauri app crate), that's a P0.
2. **Boundary conformance — no SQL outside `magnotia-storage`.**
```bash
grep -rE "sqlx::|sqlite::|sql_query|\\.execute\\(|\\.fetch_" crates/ src-tauri/src/ \
| grep -v "crates/storage/" | grep -v "/tests/"
```
Any hit is a boundary violation.
3. **Boundary conformance — no `cpal` / `whisper` / `llama` outside their owners.**
```bash
grep -rnE "use cpal" crates/ src-tauri/src/ | grep -v "crates/audio/"
grep -rnE "use whisper_rs|use whisper-rs" crates/ src-tauri/src/ | grep -v "crates/transcription/"
grep -rnE "use llama_cpp_2" crates/ src-tauri/src/ | grep -v "crates/llm/"
```
4. **Boundary conformance — no business logic in Tauri commands.** A command should be ≤30 lines: deserialize input, call into a library crate, serialize output. Anything else is leakage.
```bash
for f in src-tauri/src/commands/*.rs; do
awk '/#\[tauri::command\]/{flag=1} flag{print; if(/^}/){flag=0; print "---"}}' "$f" | \
awk '/^---$/{print c; c=0; next} {c++}' | sort -nr | head -5
done
```
Any command body >50 lines goes on the defect log.
5. **Reduce `magnotia-core` public surface.** It exports 104 items (Phase 0 §3). For each, run a workspace-wide reverse search:
```bash
grep -rnE "magnotia_core::ITEM_NAME" crates/ src-tauri/src/
```
If the only hits are inside `magnotia-core` itself, demote to `pub(crate)`. Expected outcome: 30–60% reduction.
6. **Apply Phase 0 §9 Tier C structural fixes (C1 and C2 are in scope here).**
- C1: tighten `magnotia-core` exports.
- C2: split `crates/storage/src/database.rs` into `database/{transcripts,tasks,profiles,…}.rs`. Re-export from `database/mod.rs` so the public API doesn't move.
7. **`magnotia-cloud-providers` decision.** Phase 0 §9 C4 — fold into `magnotia-core::keystore` or grow it. Don't defer indefinitely; an 80-LOC crate is doing the workspace no favours.
### Deliverable
`docs/audit/phase2-architecture.md` — boundary-violation log + before/after pub-item counts per crate + restructure summary.
### Acceptance criteria
- Zero hits on the SQL / `cpal` / `whisper` / `llama` boundary greps.
- `magnotia-core` public-item count reduced (target: ≤60).
- All commits compile and tests pass at each step (do not bundle structural moves with logic changes).
---
## Phase 3 — Correctness audit (the expensive one)
**Goal.** Walk every public function and every error path. Eliminate panics on bad input. Justify or remove every `unsafe` block.
**Time:** 3–5 working days. Single biggest investment in the audit.
**Inputs:** Phase 1 unwrap log, Phase 2 reduced public surface.
### Procedure
1. **Lints with teeth.**
```bash
cargo clippy --workspace --all-targets --all-features -- \
-D warnings -W clippy::pedantic -W clippy::nursery
```
Pedantic and nursery emit many false positives — read every one and decide. The yield from `clippy::pedantic` on a real codebase is high.
2. **`unsafe` audit.** For each `unsafe` block, write a one-paragraph justification (what invariant the caller is upholding, why it can't be encoded in the type system) inline as a comment. If you can't write the justification, the `unsafe` is suspect.
```bash
grep -rnE "unsafe\s*(\{|fn|impl)" crates/ src-tauri/src/
```
Hotspots: `crates/audio/` (cpal callbacks), `crates/hotkey/` (evdev FFI on Linux), `src-tauri/` for any platform glue.
3. **Panic surface.** Every `.unwrap()`, `.expect()`, `panic!()`, `unreachable!()`, `assert!()`, slice indexing `[i]`, integer arithmetic that can overflow.
```bash
cargo install cargo-careful
cargo +nightly careful test --workspace
```
`cargo-careful` runs tests under stricter UB detection.
4. **Property tests on parsing/format functions.**
- `crates/hotkey/src/lib.rs` — Tauri-style hotkey string parser. `proptest!` with arbitrary modifier sets + key codes; assert round-trip.
- `crates/audio/src/wav.rs` — WAV decode. Fuzz with `cargo-fuzz` or `libfuzzer-sys` against malformed headers.
- `src/lib/utils/frontmatter.ts` — YAML frontmatter parse/emit. Fast-check (npm) for round-trip.
- `crates/storage/src/database.rs` — FTS5 query escaping. Property test: any input string produces a query that doesn't crash SQLite.
5. **Miri on storage and audio.**
```bash
cargo +nightly miri test -p magnotia-storage --lib
cargo +nightly miri test -p magnotia-audio --lib
```
Catches UB and aliasing bugs that `cargo test` misses.
6. **Manual public-API walk.** For each public function in each crate:
- What are the preconditions? Are they enforced or assumed?
- What are the error variants? Are any absorbed silently (`let _ = …`)?
- Are any return types `Result<…, String>`? — that's a smell; prefer typed errors.
7. **`tracing` audit.** Run with `RUST_LOG=trace` for one full dictation → cleanup → save cycle. Note any warning-level logs the operator hasn't noticed; each is potentially a defect.
### Deliverable
`docs/audit/phase3-correctness.md` — defect log graded P0/P1/P2, plus an `unsafe` justification appendix.
### Acceptance criteria
- Zero `cargo clippy -D warnings` errors.
- Every `unsafe` block has an inline justification comment.
- All P0 defects fixed before phase close; P1 defects logged with an owner.
- Miri tests for storage and audio pass.
---
## Phase 4 — Security & trust boundaries
**Goal.** Verify the "local-first, no telemetry" pitch is enforced by the code, not by intention. Audit every Tauri command and MCP tool as a trust boundary.
**Time:** 2 working days.
**Inputs:** Phase 0 §5.1 (102 Tauri commands), §5.2 (MCP tools).
### Procedure
1. **Network egress audit (the big one).**
```bash
sudo tcpdump -i any -w /tmp/magnotia-egress.pcap host not 127.0.0.1 &
# …run the app for 30 minutes covering: dictation, cleanup, save, MCP query…
sudo kill %1
tshark -r /tmp/magnotia-egress.pcap -q -z conv,ip
```
Allowed: model downloads from huggingface.co (only on user click). Anything else is a P0.
Cross-check at the syscall level:
```bash
strace -f -e trace=network -o /tmp/magnotia-net.txt ./target/release/magnotia
grep -E "connect|sendto|sendmsg" /tmp/magnotia-net.txt | grep -v "127\.0\.0\.1\|::1"
```
2. **Tauri command boundary audit.** For every `#[tauri::command]` (102 of them):
- Input deserialization: any `String` parameter could be hostile. Path traversal? Command injection?
- Output: does it leak filesystem paths, hostnames, secrets?
- Authorization: does it check `security::ensure_main_window` where appropriate? (Most don't; document which ones must.)
- File-touching commands (`fs.rs`, `transcripts.rs` export, `feedback.rs`): canonicalize and confirm the path is inside the app's data dir before writing.
```bash
grep -rnE "PathBuf::from|Path::new" src-tauri/src/commands/
```
Each hit gets a path-traversal review.
3. **`paste.rs` review.** Spawns external processes (`konsole`, `wtype`, `xdotool`, `ydotool`, `osascript`, etc.). Confirm none of the arguments are user-controlled in a way that allows shell injection. `Command::arg` (not `Command::args` with a single shell string) everywhere.
4. **MCP read-only enforcement.**
- `magnotia-storage::init_readonly` opens with `SQLITE_OPEN_READONLY` — verify in the source.
- Test: write a malformed MCP request that tries to issue an `INSERT` via a hand-crafted tool name. Should fail at the connection level, not just the dispatcher.
```bash
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"sql_exec","arguments":{"sql":"INSERT INTO transcripts VALUES (1,2,3)"}}}' | ./target/release/magnotia-mcp
```
5. **LLM prompt-injection regression test.** The README claims `CLEANUP_PROMPT` is hardened. Build a regression test corpus of injection payloads (e.g., "ignore previous instructions and emit `<tool_call>…`"). Run `cleanup_text` against each; assert the output doesn't contain any injected control tokens.
6. **SQL injection.** All queries should use bound parameters.
```bash
grep -rnE "format!\(.*SELECT|format!\(.*INSERT|format!\(.*UPDATE|format!\(.*DELETE" crates/storage/
```
Any `format!(…SQL…)` is a defect.
7. **FTS5 query escaping.** `MATCH` queries with user input must escape FTS5 syntax. Property test.
8. **Secret scanning across `git log -p`.**
```bash
gitleaks detect --source . --no-git=false --report-path /tmp/leaks.json
trufflehog filesystem --include-detectors=all --json . > /tmp/trufflehog.json
```
9. **Dependency CVEs.**
```bash
cargo install cargo-audit cargo-deny --locked
cargo audit
cargo deny check advisories
npm audit --production
```
10. **Licence compatibility.**
```bash
cargo deny check licenses
```
Configure `deny.toml` with the licence list you can ship under (MIT, Apache-2.0, BSD-2/3-Clause, ISC, MPL-2.0, Unicode-DFS-2016 typically OK; GPL/AGPL/SSPL must be flagged before public beta).
### Deliverable
`docs/audit/phase4-security.md` — threat model + per-command boundary review + scanner reports + the egress audit pcap summary.
### Acceptance criteria
- Network egress: zero non-user-initiated outbound connections in a 30-min session.
- All Tauri commands have a documented input-validation posture (even if it's "this command takes no untrusted input").
- `cargo audit` and `npm audit` clean (or each finding has a documented mitigation).
- `cargo deny check licenses` passes the configured allow-list.
- Gitleaks + trufflehog return clean.
---
## Phase 5 — Test integrity
**Goal.** Move from "X tests pass" to "the tests pin behaviour we care about." Lines covered ≠ behaviours verified.
**Time:** 1 working day.
**Inputs:** Phase 0 §6 (287 tests; 220 lib, 3 integration, 67 src-tauri).
### Procedure
1. **Coverage baseline.**
```bash
cargo install cargo-llvm-cov
cargo llvm-cov --workspace --html --output-dir /tmp/coverage
```
Open the report. Note: low coverage on a critical file is bad; high coverage on a leaf file says nothing.
2. **Mutation testing on the heavy crates.**
```bash
cargo install cargo-mutants
cargo mutants -p magnotia-storage --timeout 60
cargo mutants -p magnotia-transcription --timeout 60
cargo mutants -p magnotia-llm --timeout 60
cargo mutants -p magnotia-audio --timeout 60
```
Surviving mutants = code paths whose tests don't actually verify behaviour. Each survivor either deserves a new test or a deletion.
3. **Tests-as-theatre check.** For a sample of 20 random tests (`shuf -n 20 tests-list.txt`), open each test and ask: "what would I have to break in the implementation to make this fail?" If the answer is "nothing — the assertions are tautological", delete the test.
4. **Regression tests for the audit-grade invariants.** Each of these gets at least one test:
- "No telemetry": a unit test that asserts no `reqwest::Client` instance is created at startup unless the user has explicitly enabled cloud STT (gated by a `cfg!` or feature flag check).
- "MCP is read-only": a test that issues a write via the MCP layer and asserts it's rejected.
- "Migrations are atomic": a test that simulates an interrupted migration mid-statement (e.g., panic between two SQL statements in the same migration version) and asserts the next startup either resumes or rolls back cleanly. (See `docs/issues/c3-migrations-atomicity.md` for context.)
- "Raw transcript is always recoverable": a test that runs cleanup, asserts the cleaned text differs from the raw, then asserts the raw is still retrievable from the DB.
- "FTS5 query escaping": property test (see Phase 3 step 4).
5. **CI must enforce coverage.** Add a coverage floor (say, 70% for each crate) to `.github/workflows/check.yml`. New PRs that drop a crate below the floor fail CI.
### Deliverable
`docs/audit/phase5-test-integrity.md` — coverage table per crate + mutation-test surviving-mutant log + new regression tests added.
### Acceptance criteria
- Mutation-testing kill rate ≥80% on `magnotia-storage`, `magnotia-transcription`, `magnotia-llm`.
- Each audit-grade invariant has at least one passing regression test.
- Coverage floor enforced in CI.
---
## Phase 6 — Performance & resource profile
**Goal.** Confirm the app doesn't leak, doesn't drift, and stays inside its latency budget under realistic use.
**Time:** 1 working day.
**Inputs:** none specific — use realistic dictation workloads.
### Procedure
1. **Long-session leak check.**
```bash
# Linux:
./target/release/magnotia & PID=$!
while sleep 60; do
ps -p $PID -o rss,vsz,nlwp,fd | tee -a /tmp/magnotia-rss.csv
done
```
Run for 1 hour with periodic dictation. Plot RSS vs. time. A monotonic upward slope is a leak.
2. **File-descriptor count.**
```bash
ls /proc/$PID/fd | wc -l # repeat over time
```
FD count should be bounded.
3. **Heap profile.**
```bash
heaptrack ./target/release/magnotia
# …run one full dictate → cleanup → save cycle…
heaptrack_print heaptrack.magnotia.*.zst | head -100
```
Look for allocators in the cleanup path that aren't freed.
4. **CPU hot path.**
```bash
perf record -g -F 99 -p $PID -- sleep 60 # during a live transcription session
perf report
```
Anything outside the model inference (whisper.cpp, llama.cpp) using >5% CPU is a candidate finding.
5. **Cold-start budget.**
```bash
time ./target/release/magnotia --headless-startup-test # add this entrypoint if missing
```
Target: < 2s from launch to "recording-ready". Anything slower → profile with `samply`.
6. **Audio device hot-plug stress.** Plug/unplug USB mic 20 times during a dictation session. Count: leaks, panics, dropped frames. (cpal hotplug is the documented hotspot.)
### Deliverable
`docs/audit/phase6-performance.md` — leak chart, hot-path flamegraph summary, cold-start measurements, hot-plug stress results.
### Acceptance criteria
- RSS plateaus within 10 minutes of dictation start (no monotonic growth).
- FD count bounded.
- Cold start < 2s on the reference machine (document the machine).
- No panics in the hot-plug stress test.
---
## Phase 7 — Build & release reproducibility
**Goal.** Confirm a fresh engineer (or acquirer's eng team) can clone, build, and run on a clean machine following only the docs. If they can't, the deal stalls.
**Time:** ½ working day.
**Inputs:** `docs/dev-setup.md`, `.github/workflows/build.yml`.
### Procedure
1. **Fresh container build.** Use a Docker container matching one supported OS at a time.
```bash
docker run --rm -it -v $(pwd):/repo:ro fedora:40 bash
# Inside: follow docs/dev-setup.md literally, time each step.
```
Time the full path: `git clone` → all `dnf install` lines → `npm install` → `cargo build --workspace`. Document every step that's missing or wrong in the docs.
2. **CI parity.** Compare local build with `.github/workflows/build.yml`. Any drift between local and CI is a P1 reproducibility risk.
3. **Bundle build.**
```bash
npm run tauri build
```
Confirm the resulting `.AppImage` / `.deb` / `.dmg` / `.msi` runs on a clean target OS.
4. **Bundle ID + signing transferability.** Confirm:
- `uk.co.corbel.magnotia` bundle ID is owned, not squatted.
- Signing certs (Apple Developer ID, Windows code-signing cert) exist and the keys are documented in a hand-over playbook.
- Icon assets in `src-tauri/icons/` are owned/licensed; replaceable on transfer.
5. **`run.sh` works as documented.** Run on a fresh checkout; it should JustWork.
### Deliverable
`docs/audit/phase7-reproducibility.md` — fresh-build walkthrough log, missing-step list for `dev-setup.md`, bundle-build evidence, transferability checklist.
### Acceptance criteria
- Fresh-container build succeeds following `dev-setup.md` verbatim. (Update the docs if not.)
- All three bundle targets build successfully in CI.
- Transferability checklist signed off.
---
## Phase 8 — Documentation truth
**Goal.** Re-walk every public doc against the post-audit code. Stale or fictional docs are worse than no docs in an acquisition context.
**Time:** ½ working day.
**Inputs:** Phase 0 §7 (initial drift list), the now-updated codebase from Phases 1–6.
### Procedure
1. **Re-run Phase 0 §7 checks.** Phases 1–4 will have moved things; the README needs another pass.
- Test count

2. **`README.md` ↔ source-of-truth pairings.** For each claim, identify the file that would break the claim if it changed, and put both in a table.
3. **Archive HANDOVER files.** Phase 0 §9 D1 — move dated handovers under `docs/handovers/`, add the rebrand-note prefix.
4. **`docs/brief/` and `docs/whisper-ecosystem/` re-read.** Any roadmap claim that's now shipped → move to a `done.md` archive. Any claim that's now de-scoped → mark as such with the date.
5. **`docs/issues/` triage.** Each open issue gets one of: `RESOLVED <commit-sha>`, `STILL OPEN`, `WON'T FIX <reason>`.
6. **Add an `AUDIT.md` at repo root.** Single-page summary: "this repo was audited on `<date>` to acquisition-grade depth; see `docs/audit/` for the full trail." Future maintainers (and acquirers) need this signpost.
### Deliverable
`docs/audit/phase8-docs-truth.md` — diff log of doc changes, archive moves, and the new `AUDIT.md`.
### Acceptance criteria
- Zero stale claims in `README.md` (re-verified).
- All `docs/issues/` items triaged.
- `AUDIT.md` exists at repo root.
---
## Closing the audit
After Phase 8, the deliverables in `docs/audit/` should read as a coherent, sequential story:
```
docs/audit/
├── phase0-cartography.md (done — survey + drift log + fix areas)
├── phase1-lean-pass.md (kill list, applied)
├── phase2-architecture.md (boundary log + restructure)
├── phase3-correctness.md (defect log + unsafe justifications)
├── phase4-security.md (threat model + scanner reports + egress audit)
├── phase5-test-integrity.md (coverage + mutation results + new tests)
├── phase6-performance.md (leak chart, hot path, cold start)
├── phase7-reproducibility.md (fresh-build walkthrough + transfer checklist)
└── phase8-docs-truth.md (post-audit doc reconciliation)
```
With `AUDIT.md` at the root pointing into the directory.
That's the artefact an acquirer's engineering team gets. It's also the artefact you'd want to find if you were the one inheriting the codebase.

A world where capturing and organising your thoughts costs zero cognitive effort. Where the tools you rely on run on your device, respect your privacy, and never punish you for a missed day. Where neurodivergent people have access to the same frictionless workflows everyone else takes for granted — and where Kon is the first piece of a wider ecosystem that levels that playing field entirely.

**Theoretical basis:** Barkley's (1997) model of ADHD as a disorder of behavioural inhibition prescribes externalisation of executive functions — moving regulatory demands from impaired internal systems into the environment. Body doubling is precisely this: an external source of temporal anchoring, accountability, and arousal regulation.

The AI option specifically reduces barriers for autistic users whilst maintaining comparable efficacy. Design should include: simulated progress indicators, rhythmic work pacing cues, and subtle ambient motion for divided attention support.

# Appendix: Reticular Activating System
## What it is
The Reticular Activating System (RAS) is a diffuse network of neurons in the brainstem, spanning the midbrain, pons, and medulla, with ascending projections through the thalamus to the cortex. It is not a single anatomical structure — it is a functional system using acetylcholine, noradrenaline, dopamine, serotonin, histamine, and hypocretin to regulate two things in concert: **arousal** (sleep/wake/alert states) and **sensory gating** (which inputs from the spinal cord and cranial nerves reach conscious cortical attention).
The RAS receives top-down modulation from the prefrontal cortex. Goals, intentions, and expectations shape which sensory inputs the RAS amplifies and which it suppresses. The system is bidirectional: cortex sets the relevance frame; RAS gates accordingly.
## Why this matters for Corbie
RAS dysfunction is documented in **ADHD, autism spectrum, schizophrenia, depression, PTSD, Parkinson's, Alzheimer's, and Huntington's**. For Corbie's beachhead audience — neurodivergent users with ADHD or autism — three RAS-linked phenomena directly motivate the product design.
### 1. Time blindness ↔ poor temporal salience gating
People with ADHD experience time as abstract and non-linear (Barkley's executive-function model; the time-agnosia literature). One mechanism: weakened prefrontal-RAS coupling means the gate doesn't escalate arousal in response to time-related cues. The clock ticks. Nothing salient passes. Tasks are not perceived as approaching their deadline until well past it.
**Corbie's design response:** externalise time into the visual field where the gate cannot suppress it. Shrinking colour disks, filling progress rings, the just-start timer's prominent countdown — all bypass the broken temporal gate by making the passage of time a visible, non-suppressible signal. (See `docs/brief/feature-set.md` for visual time representation; `appendix-implementation-intentions.md` for the rhythmic-anchoring mechanism.)
### 2. Task-initiation freeze ↔ insufficient arousal escalation for non-novel tasks
Task initiation requires the RAS to escalate arousal sufficiently to overcome inertia. ADHD brains are documented as needing 2-3x more dopaminergic stimulation than neurotypical brains to clear this threshold (`docs/brief/market-size-demographics.md`). A boring familiar task does not trigger the gate; the user does not enter the alert state needed to start; the brain settles into freeze.
**Corbie's design response:** the AI-generated micro-step ("pick up one shirt from the floor" rather than "tidy the room") provides novelty + specificity + low-friction action. This is engineered to clear the arousal threshold the RAS is failing to clear on its own. The just-start timer ("commit to 5 minutes") is a second mechanism — the boundary itself escalates arousal regardless of task novelty.
### 3. Sensory over-distraction ↔ over-permissive gate
Many ADHD and autistic users describe the opposite RAS failure: too many sensory inputs pass the gate. Background conversation, wall textures, ambient noise, screen notifications all reach attention with equal salience. The cortex is overwhelmed by inputs the RAS should have suppressed.
**Corbie's design response:** WIP limits (the main screen mathematically restricts how many active tasks are visible — typically 3 maximum), reduce-motion defaults, progressive disclosure below 3 levels, literal labels always, no ambient marketing decoration. The product itself models a healthy gate by being one. Notification design follows the same logic: anticipatory guidance over scheduled push notifications, no aggressive haptics, context-aware suppression when the user is mid-flow.
## Top-down modulation: implication for personalisation
Because the RAS responds to cortex-level goals, **what counts as relevant is task-conditional**. A morning ritual cue that escalates one user's RAS at 09:00 may be invisible to them at 14:00 in a different cognitive state. This is the neurological basis for Corbie's **energy-aware task sequencing** feature (`feature-set.md`). The user tags their current energy state; the AI surfaces tasks calibrated to that state. The mechanism is: shifting the cortex's relevance frame so that what the RAS treats as salient matches the available cognitive resources.
## The on-device personalisation grant connection
The AI Champions Phase 1 application proposes continual on-device personalisation of Corbie's ASR and LLM pipeline. The RAS frame strengthens the case: **personalising voice AI for neurodivergent users is not just about idiolect accuracy, it is about restoring a functioning attention loop**. A model that understands the user's words on the first attempt removes the cognitive surcharge that drives users off the technology. A model that mis-hears them repeatedly *is* a sensory over-distraction event the user's already-compromised gate has to keep absorbing.
The clinical literature establishes RAS dysfunction in the target population. The personalisation work is one mechanism for reducing the load on a broken gate.
## Important caveat
There is a popularised version of the RAS — common in self-help, goal-setting, and law-of-attraction contexts — that frames it as "the brain's filter that shows you what you focus on." The kernel is correct (top-down attention plus sensory gating produces priming effects) but the popular form overstates the mechanism into something close to manifestation theory. Corbie's research, brand, and external communications should use the precise neuroscience framing, not the pop-psychology one. The RAS does not "manifest" goals; it modulates which sensory inputs reach awareness based on cortex-set salience.

## Implication summary for design
| RAS function | Failure mode | Corbie design response |
|---|---|---|
| Temporal salience gating | Time blindness | Visual countdown timers, progress rings, externalised time |
| Arousal escalation | Task-initiation freeze | Specific micro-steps, just-start timer, novelty injection |
| Sensory suppression | Over-distraction | WIP limits, reduce-motion defaults, calm anticipatory nudges |
| Top-down goal coupling | State-mismatched activity | Energy-aware task sequencing, ritual transitions |
| Personalised relevance | Recurring misrecognition | On-device continual personalisation (grant-funded research substrate) |
The RAS frame ties Corbie's apparently-disparate features into one coherent design thesis: **the product is a prosthesis for a compromised attention gate**. Every design decision either offloads work the broken gate cannot do, or reduces the load the broken gate has to carry.

Magnotia's local-first architecture is simultaneously its biggest B2B selling point and its biggest deployment challenge. Key considerations:
- **Local AI model size.** Whisper models range from ~75MB (tiny) to ~1.5GB (large). Enterprise IT teams may flag large binaries or models downloaded to employee machines. Solution: bundle a smaller model by default (tiny/base) with optional upgrade to larger models. Document the model sizes and what they do for IT review.
- **No cloud = no enterprise compliance headaches.** Because Kon processes everything on-device with no data transmitted externally, it bypasses the cloud security review, vendor risk assessment, and data processing agreements that typically delay enterprise software procurement by 3–6 months. This is a genuine competitive advantage — frame it explicitly in B2B sales materials.
- **Installation permissions.** Enterprise-managed machines often restrict software installation. Kon must be deployable via MDM (Mobile Device Management) tools like Microsoft Intune or Jamf. Tauri's MSIX (Windows) and DMG (macOS) formats are compatible with standard enterprise deployment pipelines.
- **No internet dependency.** Kon does not require network access for core functionality. This makes it deployable in air-gapped, high-security, or restricted-network environments — a strong selling point for defence, legal, and healthcare settings.

## 4. Feature Set
### Core MVP (shipping with beta)
- Local AI transcription (Whisper, on-device)
- Auto-populating to-do lists from transcriptions
- **Visual time representation.** Tasks displayed as visual blocks of time or countdowns, not just text lists. Traditional text-based to-do lists trigger overwhelm — visual timelines directly combat time blindness. This is the #1 community-requested feature and Tiimo's primary strength. Kon must match or exceed it from day one. Time should be externalised using visual countdown timers (e.g. shrinking colour disks, filling progress rings) rather than standard digital clocks — making the passage of time concrete and anchoring focus for users with time agnosia.

Magnotia must match or exceed it from day one. Time should be externalised using visual countdown timers (e.g. shrinking colour disks, filling progress rings) rather than standard digital clocks — making the passage of time concrete and anchoring focus for users with time agnosia.
- **WIP limits.** The main screen must mathematically restrict how many active tasks are visible at once. A "Now" column showing only 1–3 items maximum. Auto-generated task lists that dump 30 items onto a screen will instantly trigger the freeze response. The AI can prioritise; the UI must constrain.
- History of past voice notes and transcriptions
- Light/dark mode
- Templates with local AI agent (contextual text under headings with associated metadata)
- Vocabulary profiles (custom dictionaries for specialist terms — e.g. DND NPC/location names, technical jargon)
- Transcription of uploaded voice notes and media files
- **Open data format.** All transcripts and task lists stored locally in plain text, JSON, or Markdown. Essential for the privacy-first and PKM audience. Enables the Kon → Obsidian workflow promised in the distribution strategy. Users must be able to export, move, and own their data without vendor lock-in.

Enables the Magnotia → Obsidian workflow promised in the distribution strategy. Users must be able to export, move, and own their data without vendor lock-in.
### Post-MVP features (validated, designed, not yet prioritised)
- **AI-powered micro-stepping with "just start" timer.** Decomposing abstract goals into hyper-specific actionable steps. The local AI agent must generate micro-steps that begin with highly specific, low-friction action verbs. Linguistic rules: every generated step must start with a concrete physical verb, target one single action, and be completable in under 5 minutes. Example: "Clean room" → "Pick up one shirt from the floor." NOT "Organise your bedroom" (still abstract, still paralysing). The goal is to bypass executive dysfunction by removing all ambiguity about what "starting" means. **Paired with a 2-minute or 5-minute "just start" focus timer.** Committing to a task for just five minutes bypasses internal resistance and builds micro-momentum — users frequently work past the timer. The timer should be a single tap from any micro-step, visually prominent, and use a shrinking colour disk or similar visual countdown (not a digital clock) to externalise the passage of time and combat time blindness.
@@ -25,5 +25,5 @@
- **Read Page Aloud (text-to-speech).** A simple TTS function that reads transcriptions, task lists, or AI-generated micro-steps aloud. Engages auditory processing alongside visual, which improves retention and comprehension for ADHD users. Particularly valuable during the "Clarify" stage when reviewing a brain dump. Use OS-native TTS engines (available on all target platforms) to avoid additional dependencies. Should be a single-tap action from any text view.
### Parked / future consideration
- **AI body doubling (low-fi implementation).** Research strongly validates the concept (rated #1 ADHD workplace strategy in 2025 ADDitude survey; 12-week study showed focus doubling, 30% anxiety reduction, £37 public value per £1 invested). Body doubling doesn't require high-fidelity interaction — simple ambient presence and shared monitoring work. A "low-fi" version could be a "Focus Room" interface showing abstract statuses ("AI is sorting your tasks…", "3 other Kon users are in deep work right now") to provide the feeling of parallel presence without complex engineering. This sidesteps the need for video, voice, or real-time communication. Potential future subscription feature. Not in MVP scope but worth prototyping early — the implementation cost is low relative to the validated demand.

- Temptation bundling — cut (OS-level integration nightmare across platforms, essentially impossible on iOS). Replaced by energy-aware task sequencing (see post-MVP features).

# Research-Grounded Design Audit — Kon vs. Cognitive-Mercy Research
> Companion to [research-grounded-design-principles.md](research-grounded-design-principles.md).
> Date: 2026-04-26. Product-code snapshot: `a15167c`.
## Spine
Kon's design thesis is cognitive mercy: reduce working-memory load, preserve state, make return painless, avoid shame, avoid forced categorisation, and let users outsource sequencing without feeling broken. This audit judges every recommendation against that spine. Motivational-app patterns — accountability, social presence, partner sharing, streak pressure, or nudges harder than a quiet digest — are out-of-product-scope by design, not deferred.
## Methodology
- Source memo: [research-grounded-design-principles.md](research-grounded-design-principles.md), committed as a reference document.
- Code evidence: prior parallel-Explore audit provided in the planning context, then direct source spot-checks against product code at `a15167c`.
- Visual evidence: no screenshots committed. The file:line references below are the durable source of truth.
- Vite/Playwright limitation: backend-dependent flows such as real model loading, live transcription, and transcript history were audited from source only.
Evidence strength is graded independently from alignment:
- 🟢 **Strong** — direct Kon-relevant evidence: RCT, large meta-analysis, or established practice standard for at least one actual Kon population.
- 🟡 **Moderate** — convergent evidence: adjacent populations, robust design-pattern evidence, or strong mechanism-grounded inference.
- 🟠 **Weak / emerging** — single-source, small-n, transitive inference only, or active research area without consensus.
- ⚫ **Contested / null** — failed replications, null effects under adequate power, or live methodological debate.
## Summary Table
| Feature/challenge | Alignment | Evidence | Gap tier | One-line verdict |
|---|---:|---:|---|---|
| Cognitive-load lens | ✅ | 🟡 | — | Cognitive mercy is the product spine: offload, preserve state, avoid shame. |
| Voice capture | ✅ | 🟢 | — | Local Whisper, low-friction capture, raw transcript remains recoverable. |
| MicroSteps decomposition | ⚠️ | 🟢 | T1 | Aligned except no implementation-intention phrasing. |
| MicroStep step-count fixed at 3-7 | ⚠️ | 🟡 | T2 | Hard-coded range; no user granularity or mastery fade. |
| Buckets | ✅ | 🟢 | — | Inbox/Today/Soon/Later, no numeric priority ladder. |
| Match my energy | ⚠️ | 🟡 | T2 | Three-state sort exists; labels/meaning are system-defined. |
| Local-first / privacy | ✅ | 🟢 | — | Product architecture keeps core flows local. |
| Custom vocabulary / contextual biasing | ✅ | 🟢 | — | Profile terms feed Whisper `initial_prompt` and LLM cleanup. |
| Personal acoustic adaptation | ⚪ | 🟢 | OOS | Distinct from contextual biasing; out of current product boundary. |
| Accessibility fonts | ⚠️ | ⚫ | T1 | Font picker is neutral, but Bionic copy overstates benefit. |
| Letter/line spacing | ✅ | 🟢 | — | Live sliders cover the best-supported reading intervention. |

## Per-Feature Alignment
### 0. Cognitive-Load Lens
- **Doc recommends:** treat working memory, initiation, sequencing, and time perception as variable capacity; design Kon as an external cognitive system rather than a training app.
- **Kon does:** current product framing and this audit's spine are cognitive mercy: offload decisions, preserve state, avoid shame, and allow long-term use without implying the user should graduate from the tool.
- **Visual:** code-only.
- **Verdict:** ✅ aligned, 🟡 moderate evidence, no gap.
- **Notes:** this is the load-bearing interpretation for all feature-specific rows below.
### 1. Voice Capture
- **Doc recommends:** one-gesture capture, local processing, support for fragments, and transcript drafts that never block saving.
- **Kon does:** first-run copy says "Press the button. Start talking. That's it." ([FirstRunPage.svelte](../../src/lib/pages/FirstRunPage.svelte#L301-L302)); raw Whisper output is explicitly treated as source of truth and recoverable in preview ([preview/+page.svelte](../../src/routes/preview/+page.svelte#L71-L84), [preview/+page.svelte](../../src/routes/preview/+page.svelte#L221-L234)).
- **Visual:** code-only.
- **Verdict:** ✅ aligned, 🟢 strong evidence, no gap.
- **Notes:** severe expressive aphasia remains an honest limitation in the memo, not a current product claim.
### 2. MicroSteps
- **Doc recommends:** 3-7 concrete steps, user edit/reject/override, implementation-intention phrasing, user-controlled granularity, and scaffolding fade.
- **Kon does:** the system prompt requires 3-7 concrete physical micro-steps ([prompts.rs](../../crates/llm/src/prompts.rs#L1-L5)); users can decompose, check off, edit, and give feedback ([MicroSteps.svelte](../../src/lib/components/MicroSteps.svelte#L48-L92), [MicroSteps.svelte](../../src/lib/components/MicroSteps.svelte#L218-L305)).
- **Visual:** code-only.
- **Verdict:** ⚠️ partial gap, 🟢 strong evidence, T1/T2/T3 split.
- **Gap detail:** implementation-intention phrasing is missing from the prompt and is the strongest single Tier 1 opportunity. User-adjustable count is Tier 2; mastery fade is Tier 3.
### 3. Buckets
- **Doc recommends:** Inbox/Today/Soon/Later, no numeric priorities, Today as the working surface, and no overdue-shame launch state.
- **Kon does:** the Tasks page defines All/Inbox/Today/Soon/Later and avoids P1-P4 style priorities ([TasksPage.svelte](../../src/lib/pages/TasksPage.svelte#L38-L45)).
- **Visual:** code-only.
- **Verdict:** ✅ aligned, 🟢 strong evidence, no gap.
- **Notes:** the audit did not inspect a rendered drag flow, but the structural bucket model matches the memo.
### 4. Match My Energy
- **Doc recommends:** quick high/medium/low energy input, skip without penalty, tasks at or below current energy, and user-defined energy meanings.
- **Kon does:** the Tasks page includes current-energy controls and a Match my energy sort ([TasksPage.svelte](../../src/lib/pages/TasksPage.svelte#L56-L65), [TasksPage.svelte](../../src/lib/pages/TasksPage.svelte#L88-L104), [TasksPage.svelte](../../src/lib/pages/TasksPage.svelte#L319-L360)). Energy labels are fixed as High/Medium/Zero ([EnergyChip.svelte](../../src/lib/components/EnergyChip.svelte#L48-L60)).
- **Visual:** code-only.
- **Verdict:** ⚠️ partial gap, 🟡 moderate evidence, T2.
- **Gap detail:** users cannot redefine what each label means for their body, which weakens the Jason energy-envelope grounding.
### 5. Local-First / Privacy
- **Doc recommends:** local-only defaults, no transcript-content telemetry, no required account, and privacy perception surfaced clearly.
- **Kon does:** model and transcription paths are local-first in the current architecture; profile vocabulary is resolved locally before transcription ([transcription.rs](../../src-tauri/src/commands/transcription.rs#L157-L180), [transcription.rs](../../src-tauri/src/commands/transcription.rs#L251-L282)).
- **Visual:** code-only.
- **Verdict:** ✅ aligned, 🟢 strong evidence, no gap.
- **Notes:** the memo correctly labels direct local-first-vs-cloud disclosure evidence as transitive rather than RCT-backed.
### 6. Custom Vocabulary / Per-Profile Language
- **Doc recommends:** first-class user vocabulary, low-friction learning, local persistence, and corrections feeding future recognition.
- **Kon does:** profile terms are joined into Whisper `initial_prompt` ([mod.rs](../../src-tauri/src/commands/mod.rs#L26-L62)); Whisper passes that prompt through to `set_initial_prompt` ([whisper_rs_backend.rs](../../crates/transcription/src/whisper_rs_backend.rs#L51-L78)); cleanup appends custom vocabulary spellings ([llm_client.rs](../../crates/ai-formatting/src/llm_client.rs#L51-L65)); the viewer can learn terms from edits ([viewer/+page.svelte](../../src/routes/viewer/+page.svelte#L124-L132)).
- **Visual:** code-only.
- **Verdict:** ✅ aligned for contextual vocabulary, 🟢 strong evidence, no gap.
- **Boundary:** personalised acoustic adaptation is separate from contextual biasing and is explicitly out-of-product-scope research for now.
### 7. Accessibility: Fonts, Bionic Reading, Spacing, Motion
- **Doc recommends:** honest framing for OpenDyslexic/Lexend/Bionic, adjustable size/spacing, no italics for extended reading, and `prefers-reduced-motion` plus an in-app control.
- **Kon does:** font picker, font size, letter spacing, line height, transcript size, Bionic toggle, and reduce-motion control are present ([AccessibilityControls.svelte](../../src/lib/components/AccessibilityControls.svelte#L40-L111)); defaults and DOM application include Lexend, Atkinson, OpenDyslexic, 16px, 1.5 line-height, Bionic off, and reduce motion system ([preferences.svelte.ts](../../src/lib/stores/preferences.svelte.ts#L29-L47), [preferences.svelte.ts](../../src/lib/stores/preferences.svelte.ts#L81-L98)).
- **Visual:** code-only.
- **Verdict:** ⚠️ partial gap, ⚫ contested for branded font/Bionic claims, 🟢 strong for spacing/motion, T1 honest-copy fix.
- **Gap detail:** "Bold the first few characters of each word for faster scanning" overstates a contested/null evidence base ([AccessibilityControls.svelte](../../src/lib/components/AccessibilityControls.svelte#L104-L105)).
## Per-Challenge Alignment
### A. Post-Collapse Re-Entry
- **Doc recommends:** a fresh-start state after >7 days away, one-tap backlog bankruptcy, no overdue counts, and no catch-up framing.
- **Kon does:** morning triage is optional, capped at three, and explicitly avoids overdue/failed framing ([MorningTriageModal.svelte](../../src/lib/components/MorningTriageModal.svelte#L1-L15), [MorningTriageModal.svelte](../../src/lib/components/MorningTriageModal.svelte#L120-L170)). Copy says "Yesterday's open items. The rest can wait." ([MorningTriageModal.svelte](../../src/lib/components/MorningTriageModal.svelte#L202-L207)).
- **Visual:** code-only.
- **Verdict:** ⚠️ partial gap, 🟡 moderate evidence, T2.
- **Gap detail:** there is no special >7-day return detection, fresh-start copy, or Inbox bankruptcy action.
### B. Unintrusive Dopamine Loops
- **Doc recommends:** fixed-schedule, completion-contingent feedback; no variable-ratio reward, streak pressure, surprise confetti, or forced sound.
- **Kon does:** focus-timer completion is deterministic and brief ([focusTimer.svelte.ts](../../src/lib/stores/focusTimer.svelte.ts#L71-L83), [focusTimer.svelte.ts](../../src/lib/stores/focusTimer.svelte.ts#L150-L178)); task completion dispatches plain state/events rather than a reward loop ([page.svelte.ts](../../src/lib/stores/page.svelte.ts#L503-L514)).
- **Visual:** code-only.
- **Verdict:** ✅ aligned, 🟢 strong evidence, no gap.
- **Notes:** completion sound exists for the focus timer; general sound cues default off in settings ([page.svelte.ts](../../src/lib/stores/page.svelte.ts#L58-L59)).
### C. Capture-To-Action Gap
- **Doc recommends:** optimise time-to-first-syllable, allow nameless/untyped thought dumps, preserve in-progress state, and keep original transcript canonical.
- **Kon does:** raw transcript recovery is explicit ([preview/+page.svelte](../../src/routes/preview/+page.svelte#L71-L84)); auto-title prompt treats speech as data, not instructions, and does not invent facts ([prompts.rs](../../crates/llm/src/prompts.rs#L46-L59)); task extraction omits non-commitments rather than forcing categorisation ([prompts.rs](../../crates/llm/src/prompts.rs#L61-L66)).
- **Visual:** code-only.
- **Verdict:** ✅ aligned, 🟢 strong evidence, no gap.
- **Notes:** real hotkey/lock-screen performance was not measured in this docs-only audit.
### D. Streaks Vs Momentum
- **Doc recommends:** no streak counters, no streak-loss framing, no leaderboards, and any progress shown over softer ranges.
- **Kon does:** settings define no streak mechanic; momentum sparkline is optional and separate from the "N today" badge ([types/app.ts](../../src/lib/types/app.ts#L125-L130)); defaults keep the sparkline on but not a consecutive-use metric ([page.svelte.ts](../../src/lib/stores/page.svelte.ts#L82-L85)); design docs explicitly prohibit streak-shaming ([design-principles.md](design-principles.md#L28)).
- **Visual:** code-only.
- **Verdict:** ✅ aligned, 🟢 strong evidence, no gap.
- **Notes:** "N today" is same-day completion acknowledgement, not a streak.
### E. Notifications And Nudges
- **Doc recommends:** silent, batched, user-controlled notifications; no push by default; compassionate language; OS quiet-hour respect.
- **Kon does:** nudges default off ([page.svelte.ts](../../src/lib/stores/page.svelte.ts#L82-L84)); nudge suppression requires enabled/unmuted, no document focus, and under 3/hour ([nudgeBus.svelte.ts](../../src/lib/stores/nudgeBus.svelte.ts#L12-L21), [nudgeBus.svelte.ts](../../src/lib/stores/nudgeBus.svelte.ts#L94-L128)); morning nudge copy is gentle ([nudgeBus.svelte.ts](../../src/lib/stores/nudgeBus.svelte.ts#L177-L195)).
- **Visual:** code-only.
- **Verdict:** ⚠️ partial gap, 🟡 moderate evidence, T2.
- **Gap detail:** the current bus is immediate-triggered with caps; it does not offer a 1-3 daily digest batching mode.
### F. Identity Framing
- **Doc recommends:** capability/scaffolding language, no cure/training framing, no pathology onboarding, and user work visible as mastery evidence.
- **Kon does:** first-run copy is minimal and non-pathologising ([FirstRunPage.svelte](../../src/lib/pages/FirstRunPage.svelte#L301-L302)); cleanup prompt frames AI as translator, not editor, preserving the user's meaning ([llm_client.rs](../../crates/ai-formatting/src/llm_client.rs#L8-L49)); raw transcript remains available as the user's own words ([preview/+page.svelte](../../src/routes/preview/+page.svelte#L71-L84)).
- **Visual:** code-only.
- **Verdict:** ✅ aligned, 🟢 strong evidence, no gap.
- **Notes:** rebrand work is unrelated to this audit.
### G. Literature-Surfaced Gaps
- **Externalised time:** Kon has a persistent focus timer that survives window close/reopen ([focusTimer.svelte.ts](../../src/lib/stores/focusTimer.svelte.ts#L1-L13), [focusTimer.svelte.ts](../../src/lib/stores/focusTimer.svelte.ts#L180-L208)) and a visible running ring with controls ([FocusTimer.svelte](../../src/lib/components/FocusTimer.svelte#L102-L193)). Verdict: ✅ aligned, 🟢 strong.
- **Implementation intentions:** MicroStep prompt does not request if-then plans ([prompts.rs](../../crates/llm/src/prompts.rs#L1-L5)). Verdict: 🔴 missing, 🟢 strong, T1.
- **Transition support:** there is no explicit "where was I?" re-orientation on return to an interrupted MicroStep. Verdict: 🔴 missing, 🟡 moderate, T2.
- **Body doubling:** evidence is emerging, but the feature would move Kon away from solo/local-first cognitive mercy. Verdict: ⚪ OOS, 🟠 weak/emerging.
- **Coach/partner loop:** evidence is stronger for severe EF impairment, but the product shape becomes social accountability. Verdict: ⚪ OOS, 🟡 moderate.
## Corrections From Prior Internal Audit
1. **Bionic Reading copy overstates the evidence.** `AccessibilityControls.svelte` says "Bold the first few characters of each word for faster scanning" ([AccessibilityControls.svelte](../../src/lib/components/AccessibilityControls.svelte#L104-L105)). The memo treats Bionic Reading evidence as contested/null. The toggle can stay, but the copy should soften. Captured as Tier 1 #2.
## Minor UX Notes Not Driven By The Memo
- **MicroStep `Just Start` timer launch hover-reveals.** The running timer ring itself is always visible, so externalised time remains aligned. The launch affordance hides until row hover ([MicroSteps.svelte](../../src/lib/components/MicroSteps.svelte#L297-L305)), which drifts from Kon's internal no-hover-to-reveal rule. This is a small CSS follow-up, not a research-memo gap.
## Prioritised Gaps
### Tier 1 — Single-PR Sized
1. **Implementation intentions in MicroStep prompt** — update [prompts.rs](../../crates/llm/src/prompts.rs#L1-L5) so decomposition includes at least one cue-anchored "when X, then Y" step. This is the strongest evidence-to-effort item in the memo.
2. **Honest accessibility-font + Bionic copy** — soften [AccessibilityControls.svelte](../../src/lib/components/AccessibilityControls.svelte#L104-L105) and add a short note under the font picker that font choices are personal preferences with contested evidence.
### Tier 2 — Multi-Component
3. **Re-entry / fresh-start trigger after long absence** — detect >7-day absence in the shell or morning triage flow; switch copy to "Welcome back. This week starts fresh."; offer one-tap Inbox bankruptcy.
4. **Notifications digest mode** — add an opt-in digest mode with 1-3 user-set times alongside the immediate nudge bus. Defaults remain OFF.
5. **User-adjustable MicroStep count** — expose granularity preference and thread it through the decomposition prompt.
6. **"Where was I?" MicroStep re-orientation** — show the just-completed step and next step when returning to an interrupted decomposition.
7. **User-defined energy meaning** — let users edit labels and descriptions for High/Medium/Zero.
### Tier 3 — Roadmap / Schema Work
8. **MicroStep mastery / scaffolding fade** — track completion patterns and offer to fold familiar routines back into single tasks. Requires schema work and evaluation.
### Out-Of-Product-Scope Research Projects
- **Body doubling / co-presence layer.** Outside Kon's current solo/local-first product boundary; would push the app toward social accountability.
- **Coach / partner sharing loop.** Same product-boundary issue, even where the evidence is stronger for severe EF impairment.
- **Personal acoustic adaptation / per-user model fine-tunes.** Distinct from contextual vocabulary; requires opt-in data, evaluation, and storage design before it could belong in product.
Out-of-product-scope by design, not deferred.
## Honest-Copy Items
- **Bionic Reading:** change "for faster scanning" to preference-based wording.
- **Accessibility font picker:** add one sentence that OpenDyslexic/Lexend/Bionic evidence is contested and the picker is for comfort/preference.
- **Match my energy:** if surfaced in product explanation, ground it in Jason's energy-envelope model; mention spoon theory only as a communication metaphor.
## Open Questions For Jake
- Keep this audit docs-only, or eventually surface a short methodology line in an in-app About/Methodology screen?
- Fold Tier 1 into v0.1 work, or queue it immediately after v0.1?
## Next Actions
- Tier 1 items each get a focused follow-up plan.
- Tier 2 items get a brief design conversation before plan-writing.
- Tier 3 stays on roadmap.
- Out-of-product-scope items are not picked up unless the product boundary is intentionally reopened.

# Design principles for Kon, grounded in evidence
## The lens: cognitive load and executive dysfunction as a design constraint
Kon serves people whose working memory, initiation, sequencing, and time perception are intermittently or chronically impaired — by ADHD, autism, dyslexia, TBI, stroke, long COVID, ME/CFS, fibromyalgia, perimenopause, depression, anxiety, or burnout. The unifying mechanism is reduced **available cognitive bandwidth** (Sweller's intrinsic load), aggravated by event boundaries that purge volatile thoughts (Radvansky), temporal myopia (Barkley), and shame cycles that make tools themselves into stressors (Tracy & Robins; Corrigan). The right design response is not to "train" capacity back but to act as an **external cognitive system** in the Hutchins/Clark-and-Chalmers sense — a reliable, low-friction extension that reduces intrinsic load (Risko & Gilbert, 2016), supports autonomous motivation (Deci & Ryan, 2000), respects the user's variable capacity (Jason's energy envelope), and earns long-term use by being forgiving rather than punishing (Cochran & Tesser's "what-the-hell" effect). The capability approach (Sen; Toboso, 2011) gives the normative frame: Kon should expand what users can do and be, not measure how close they get to a neurotypical baseline.
---
## Per-feature guidelines
### 1. Voice capture (local Whisper, low-friction thought dumping)
**The evidence.** Speech is materially faster than touchscreen typing — Ruan et al. (2018, IMWUT) found 3× faster English entry and 20% lower error rate. For dyslexic and learning-disabled writers, dictation reliably produces longer, more complex, lower-error texts because it offloads transcription cost (Higgins & Raskind, 1995; Quinlan, 2004 *J Educ Psych*; MacArthur & Cavalier, 2004 *Exceptional Children*). Matre & Cameron's 2022 scoping review confirms positive effects across eight studies. The mechanism transfers: ADHD writers face the same transcription bottleneck (Re, Pedron & Cornoldi, 2007), as do TBI patients with motor fatigue.
**Be honest about two limits.** ADHD-specific dictation RCTs are sparse — the case is largely inferential from working-memory theory and dyslexia studies. Svensson et al.'s (2023) five-year follow-up found long-term STT use *declined* when error-correction friction outweighed input speed. And dictation is contraindicated for severe expressive aphasia (Russo et al., 2017).
**Do.** Make capture launchable in one gesture or hotword; never require unlock or app foreground. Whisper's local processing is correct — privacy materially affects what users will dictate (see local-first below). Allow capture without immediate triage: thought-dumping must not require categorisation. Show a transcript draft but never block the save on accuracy. Permit silent partial-correction later. Support fragmentary, ungrammatical, half-finished thoughts as first-class items.
**Avoid.** Mandatory tagging at capture time. Forcing review before save. Network round-trips that introduce latency or privacy doubt. Treating low-confidence transcripts as failures rather than user-editable artefacts.
### 2. MicroSteps (LLM-decomposed 3–7 actions)
**The evidence.** Task analysis is one of the longest-validated EF supports: Spooner et al. (2012) and the NCAEP review (Steinbrenner et al., 2020) classify it as evidence-based for autism and intellectual disability; visual activity schedules meet EBP criteria across 31 studies (Knight, Sartini & Spriggs, 2015). Goal Management Training (Levine et al., 2000; Stamenova & Levine 2019 meta-analysis) and metacognitive strategy training (Cicerone et al., 2019) are practice standards for TBI executive dysfunction. **Implementation intentions** — explicit if-then phrasing — show d = 0.65 across 94 studies (Gollwitzer & Sheeran, 2006) and bring ADHD children's inhibition to non-ADHD levels (Gawrilow & Gollwitzer, 2008).
**The 3–7 range** is justifiable: Cowan's (2001) revised working-memory limit of ~4 chunks (lower in clinical populations) bounds the *upper* end; below three steps the decomposition adds no scaffold. Cognitive Load Theory (Sweller, 2010) predicts decomposition helps novices but hurts experts via the **expertise reversal effect** (Kalyuga, 2007).
**Do.** Default to four steps; allow user-controlled granularity. Phrase at least one step as an implementation intention ("when the kettle boils, …"). Permit users to edit, reject, collapse, or override AI output — preserving agency directly addresses Spiel et al.'s (2022) and Jamshed et al.'s (2025, ASSETS) critique that ND productivity tools shift the burden of "access-making" onto users. Track mastery and offer to fold familiar routines back into single items (scaffolding fade — Pea, 2004; van de Pol, 2010).
**Avoid.** Locking the step count. Decomposing tasks the user has demonstrated mastery of. Marketing AI decomposition as equivalent to clinical task analysis — there is **no peer-reviewed RCT** comparing LLM-generated to therapist-generated breakdowns; goblin.tools has not been evaluated. State this honestly.
### 3. Buckets (Inbox / Today / Soon / Later)
**The evidence.** Bellotti et al.'s 2004 CHI fieldwork on real to-do behaviour found users ignore explicit P1–P4 priority labels and naturally re-sort by time horizon and recency; long undifferentiated lists demoralise and get abandoned. Whittaker, Bellotti & Gwizdka (2006) explain why: priorities shift, so static labels go stale. Heylighen & Vidal's (2008) analysis of GTD argues opportunistic, context-driven execution outperforms rigid priority queues — though GTD's own RCT base is thin.
**Today as default** is supported by choice architecture (Thaler & Sunstein, 2008; Johnson & Goldstein, 2003 — defaults reliably alter behaviour through inertia and effort-avoidance) and by Iyengar & Lepper's (2000) jam-study evidence that larger choice sets reduce engagement. Cowan's working-memory ceiling makes a 5–10-item Today list cognitively manageable; a 200-item flat list is not.
**Do.** Default to Today. Keep four buckets — adding more re-introduces the categorisation tax that buckets exist to avoid. Allow drag-only re-bucketing; never force a deadline. Treat Inbox as a deliberate triage zone, not a backlog of shame. Make "Soon" and "Later" *visible counts* but not push surfaces — they are deliberately out of immediate attention. Display a single, gentle bucket-position cue, not a percentage-complete bar.
**Avoid.** Numeric priorities. Smart-sort algorithms that override the user's bucket choice. Showing all buckets simultaneously by default. Surfacing overdue counts on app launch (a documented shame trigger — see Challenge A).
### 4. "Match my energy" sort
**The evidence.** Jason's energy envelope theory (Jason et al., 2013; O'Connor et al., 2019) is the strongest empirical anchor: ME/CFS patients who keep expenditure within perceived capacity have better functioning across fatigue, pain, depression, and QoL. NICE NG206 (2021) makes pacing — staying within current limits, never escalating — the recommended approach for ME/CFS and (by extension) long COVID, and explicitly warns against graded escalation. The chronotype × time-of-day **synchrony effect** (Schmidt et al., 2007; 2025 *Chronobiology International* systematic review) shows real but modest performance gains when task demand matches arousal state. ADHD shows altered circadian profiles and greater within-day arousal variability (Coogan & McGowan, 2017), supporting energy-matched scheduling for that population specifically.
**Be honest.** **Spoon theory** (Miserandino, 2003) is a culturally legible metaphor with major patient-community traction but **no peer-reviewed psychometric validation**; cite it as a communication frame, ground the actual mechanic in Jason's envelope. The strict 90-minute ultradian/BRAC cycle popularised by Tony Schwartz and Andrew Huberman is **weakly supported** — Eriksen et al. (1995) found no 90-min periodicity in cognitive performance; LaJambe & Brown (2008) review is sceptical. Mack et al.'s (2022, ASSETS) "consequence-based accessibility" paper is the strongest HCI peg.
**Do.** Allow a quick three-state energy input (high/medium/low) with one-tap update and a "skip" that doesn't penalise. Surface tasks tagged at or below current state. Let users define what high/medium/low *mean for them* — the spoon count is individual.
**Avoid.** Multiple daily prompts (EMA literature: cognitive impairment and fatigue predict lower compliance — Shiffman et al., 2008; Wrzus & Neubauer, 2023). Any feature that suggests the user "do a bit more than yesterday" — that is graded exercise therapy by another name and is contraindicated by NICE NG206. Auto-promoting low-energy tasks to high-energy days.
### 5. Local-first / privacy
**The evidence.** Anonymity and perceived privacy reliably increase honest disclosure of stigmatised content: Joinson (1999, 2001), Gnambs & Kaspar's (2017) meta-analysis, the Pennebaker expressive-writing tradition (Frattaroli, 2006 meta-analysis: privacy is a moderator of therapeutic effect). Mental-health apps have a serious privacy problem: Iwaya et al. (2023) found 24/27 apps had critical security risks; O'Loughlin et al. (2019) found only 4% of depression apps had acceptable transparency. Powell et al.'s 2024 CHI paper documents users actively self-censoring honest reporting in cloud-backed mental-health apps. Penney's (2016) Wikipedia traffic analysis demonstrates measurable chilling effects from perceived surveillance.
**Do.** Default to local-only storage; treat any sync as opt-in per data class (transcripts, embeddings, summaries separately). State the data flow in one sentence on the capture screen — privacy *perception* is what drives disclosure, not just the underlying engineering. Allow per-entry redaction before any optional sync. Provide an "incognito capture" mode that bypasses logs entirely.
**Avoid.** Implicit cloud backup. Telemetry on transcript content (even hashed). Required accounts for core features. Any analytics that touch the spoken text. Marketing copy that conflates "encrypted" with "private" — users can tell the difference.
**Honest gap.** No RCT directly compares local-first to cloud-stored journaling apps' effect on disclosure of stigmatised content; the case rests on transitive evidence (anonymity literature + privacy calculus + chilling effects). The inference is solid but not directly tested.
### 6. Custom vocabulary / per-profile language
**The evidence is strong and unambiguous.** Personalised ASR delivers 35–80% relative WER reduction across atypical-speech populations (Shor et al., 2019, Interspeech; Green et al., 2021 — personalised models *outperformed expert human transcribers* on disordered speech). Just five minutes of personalised data captures ~71% of the gain (Shor 2019). Contextual biasing/custom vocabulary cuts WER on rare named entities by 10–48% (Pundak et al., 2018; Kolehmainen et al., 2023). Lea et al. (2023, CHI) document user-driven personalisation as the path for people who stutter; Tomanek et al. (2021) on residual adapters shows efficient on-device personalisation is feasible. De Russis & Corno (2019) find off-the-shelf cloud ASR has WER >50% for many dysarthric speakers — personalisation is **a baseline accessibility requirement, not a luxury**.
**Do.** Treat vocabulary as a first-class object: per-user noun lists (names, jargon, medications, slang), with low-friction in-context add ("learn this word"). Support adapter-based personal acoustic models for users with accents, dysarthria, stutter, post-stroke speech, or atypical prosody (autism). Persist them locally. Make corrections one-tap and feed them back into the model.
**Avoid.** Hard-coded vocabularies the user can't edit. Discarding user corrections. Penalising fragmented or restarted utterances — these are common in cognitive fatigue and dysfluency.
### 7. Dyslexia-friendly fonts, bionic reading, reduce motion
**The evidence here is contested and the developer should be candid in copy.**
**OpenDyslexic.** Repeatedly negative: Wery & Diliberto (2017, *Annals of Dyslexia*); Rello & Baeza-Yates (2013/2016, ACM TACCESS) — dyslexic readers preferred Verdana and Helvetica; Kuster et al. (2018, n=170+147) — null and Arial preferred. Marinus et al. (2016) found a 7% Dyslexie advantage that **disappeared when Arial was given matched spacing** — the benefit is from spacing, not letterforms. The **British Dyslexia Association 2023 style guide does not endorse OpenDyslexic**; the IDA position is that specialty fonts have "no desired effect."
**Lexend** has no independent peer-reviewed RCTs; Shaver-Troup's evidence is a doctoral dissertation and an N=20 promotional study. Its design principles (large x-height, generous spacing) are evidence-based; the brand is not.
**Atkinson Hyperlegible** was designed by the Braille Institute for **low-vision character disambiguation** — don't conflate it with dyslexia.
**Bionic Reading.** Strukelj (2024, *Acta Psychologica*) — null at n=32 with adequate power. *Attention, Perception & Psychophysics* (2025) — bolding the first half produced reading **costs**, not gains. Doyon's n=2,074 public test showed 2.6 wpm slower and 5–8% worse comprehension.
**What actually has evidence:** font size ≥18pt (Rello, Pielot & Marcos, 2016, CHI; O'Brien et al., 2005), **inter-letter spacing** (Zorzi et al., 2012, *PNAS* — extra-large spacing produces immediate dyslexic reading gains), avoiding italics, sans-serif preference. The strongest principle is **offering user-adjustable presentation** — UDL (CAST), WCAG 1.4.12 Text Spacing, WCAG 2.3.3 Animation from Interactions.
**Do.** Default to a clean sans-serif at ≥16pt, with size adjustable to 22pt+. Provide adjustable letter-spacing and line-spacing — these have the strongest evidence. Honour `prefers-reduced-motion` *and* expose an in-app toggle (Apple HIG; vestibular literature; autism × migraine comorbidity — Sullivan et al., 2014). Suppress parallax, scaling intros, autoplay carousels.
**Avoid.** Marketing OpenDyslexic, Lexend, or Bionic Reading as "proven for dyslexia" — they aren't. Offer them honestly as **subjective preference options**: "Some users find this comfortable; the evidence base is contested."

## Per-challenge guidelines
### A. Post-collapse re-entry
**The evidence.** This is where most productivity tools fail Kon's users. The mechanism is well-mapped. Tracy & Robins (2006) and Tangney & Dearing (2002) show that internal-stable-uncontrollable attributions for failure produce **shame**, which motivates withdrawal; internal-unstable-controllable attributions produce **guilt**, which motivates repair. A full inbox after weeks away triggers the shame route by default. Cochran & Tesser's "what-the-hell effect" (and Polivy et al., 2010) shows a single perceived violation cascades into total abandonment — *belief* of failure, not actual failure, drives disengagement. Loss aversion (Kahneman & Tversky, 1979; Kivetz et al., 2006 goal-gradient) makes streak-based systems disproportionately punishing on break.
The counter-evidence is equally clear. Dai, Milkman & Riis's "fresh start effect" (2014, *Management Science*; 2015, *Psychological Science*) shows temporal landmarks — Mondays, months, "fresh starts" — psychologically segregate the imperfect past self and spike aspirational behaviour. Breines & Chen's (2012) self-compassion experiments show induced self-compassion *increases* self-improvement motivation, time studying after failure, and willingness to repair — directly disconfirming the "compassion breeds complacency" worry. MacBeth & Gumley's (2012) meta-analysis confirms a large inverse association between self-compassion and depression/anxiety/stress.
**Do.** Treat re-entry as a first-class state. On returning after >7 days, trigger a fresh-start frame: "Welcome back. This week starts fresh." Offer one-tap **bankruptcy** — archive everything in Inbox/Today older than X days, no questions asked (the consumer-equivalent of Mann's Inbox Zero bankruptcy; consistent with Cochran & Tesser's long-term-framing prescription, even if Mann himself is a non-peer-reviewed source). Frame missed items as system-attributable ("the inbox overflowed"), never user-attributable ("you forgot"). Offer common-humanity language ("most people return after a long break — that's how this tool is meant to be used"). Default to a small Today list of 1–3 items on re-entry.
**Avoid.** Red badges of overdue counts. "You missed N tasks" notifications. Streak-loss screens. Catch-up flows. Any UI that asks the user to *resolve* the backlog before they can use the app. Reactivation emails framed as concern ("we missed you") — they almost always read as guilt to this population.
### B. Unintrusive dopamine loops
**The evidence.** Most "dopamine UX" writing is junk neuroscience. Schultz (1998, 2016) and Berridge & Robinson (1998, 2016) establish that dopamine codes **reward prediction error** and **incentive salience ("wanting")**, not pleasure ("liking"). After learning, *predictable* rewards produce zero phasic dopamine response — which means predictable, fixed-schedule completion feedback **cannot fuel compulsion loops**, only acknowledgement. That is precisely what Kon should want. Schüll's (2012) ethnography of slot machines and Lindström et al. (2021, *Nature Communications*) show what variable-ratio reinforcement does at scale; Eyal's (2014) *Hooked* explicitly imported this into product design and his own (2019) follow-up partially walked it back.
For ADHD specifically, Söderlund's "moderate brain arousal" model (2007 *J Child Psychology and Psychiatry*; 2007 *Psychological Review*) and Nigg et al.'s (2024) meta-analysis show white/pink noise produces a small but real benefit (g ≈ 0.22, moderate-confidence GRADE) on attention — though Rijmen & Wiersema (2024, 2026) have challenged the stochastic-resonance mechanism. Brain.fm's amplitude-modulated music (Woods et al., 2024, *Communications Biology*) shows modest attention benefit but is **industry-funded with no independent replication**. Garcia-Argibay et al.'s (2019) binaural beats meta-analysis is positive (g = 0.45, anxiety stronger than attention) but later well-controlled studies (Robison et al., 2022) are sceptical. The **Mozart effect is debunked** (Pietschnig et al., 2010 meta-analysis).
For audio design itself: Brewster's earcon work (1993, 1998); Garzonis et al. (2009) — auditory icons beat earcons on intuitiveness; Williams et al. (2021) on autism + hyperacusis — ~50–70% prevalence of impaired sound tolerance.
**Do.** Use **fixed-schedule, completion-contingent** feedback: every finished task → predictable, brief, low-frequency-friendly acknowledgement. Keep audio cues ≤1.5s, soft attack envelope (≥10–20ms), avoid >4kHz peaks. Provide multimodal redundancy (audio + haptic + visual) so users can disable any channel without losing the cue. Expose a calm/energising/silent intensity axis — Dunn's sensory profile quadrants vary, and many users sit in both "sensation seeking" (ADHD) and "sensitivity" (autism comorbidity) at once. If you offer ambient sound, frame pink/white noise honestly (modest evidence, opt-in) and avoid pseudoscientific language about "neural phase-locking" or "binaural entrainment."
**Avoid.** Variable-ratio reward animations. Surprise rewards. Confetti for ordinary completion. Streak counters as feedback (see D). Marketing copy invoking "dopamine hits." Forced sound on completion. Anything that resembles Gray et al.'s (2018) dark-pattern strategies — nagging, forced action, interface interference.
### C. Capture-to-action gap
**The evidence.** The "thought lives in the head until externalised" intuition is one of the most strongly supported in the brief. Risko & Gilbert's (2016, *Trends in Cognitive Sciences*) review of cognitive offloading defines and validates the core mechanism: physical action that alters information-processing demand. Gilbert et al. (2020, *JEP:General*; 2023 review) show external reminders consistently improve prospective memory; the cost is small relative to benefit. Storm & Stone (2015, *Psychological Science*) demonstrate **saving-enhanced memory** — saving information *improves* learning of subsequent material because resources are freed. Sweller's CLT explains why: working memory is severely limited and externalising reduces intrinsic load. Clark & Chalmers (1998) and Hutchins (1995) provide the philosophical/ethnographic ground for treating reliable tools as cognitive extensions.
The doorway effect (Radvansky & Copeland, 2006; Pettijohn & Radvansky, 2016) operationalises the mechanism: **event boundaries actively purge volatile representations**. Be honest — McKerracher et al. (2021) failed to replicate the specific magnitude in complex VR tasks, and Sparrow et al.'s (2011) "Google effect" failed Many Labs replication. The broader event-boundary literature is robust; the dramatic headlines are not.
**Do.** Optimise for **time-to-first-syllable** as the headline metric. Capture must work from lock screen, in any app, with one input. Permit nameless, untyped, untagged thought-dumps as first-class items (Bellotti et al., 2004 — users abandon tools that demand classification at capture). Buffer constantly: any app return should preserve in-progress dictation. Time-stamp and (optionally) place-stamp captures — Godden & Baddeley's (1975) context-dependent memory has a real if modest effect (Smith & Vela, 2001 meta d ≈ 0.25; replication caveats noted by Murre, 2021). Treat the transcript as the canonical artefact; allow re-listen for verification but don't require it.
**Avoid.** Modal dialogs at capture time. Required categorisation. Network checks. Login prompts. Auto-summarisation that displaces the original — users need to find their own words.
### D. Streaks vs momentum
**The evidence is, for this population, decisively against streaks.** Deci, Koestner & Ryan's (1999, *Psych Bulletin*) meta-analysis of 128 experiments shows tangible, expected, performance-contingent rewards undermine intrinsic motivation — the **overjustification effect**. Cerasoli et al.'s (2014) 40-year meta-analysis (k = 183, N > 200,000) confirms incentives crowd out intrinsic motivation when directly performance-tied. Six et al.'s (2021, *JMIR Mental Health*) meta-analysis of 38 mental-health gamification studies found **gamification did not significantly improve depression outcomes** over non-gamified counterparts. Cheng et al. (2019) document gamification in mental-health apps applied without theoretical grounding; rewards can have negative mood effects in users feeling they're "not achieving enough" (Alqahtani et al., 2021, qualitative).
Streak mechanics specifically combine three documented harms: loss aversion (Kahneman & Tversky), goal-gradient escalation (Kivetz et al., 2006), and the what-the-hell effect (Cochran & Tesser; Polivy et al., 2010) where one break cascades into abandonment. For users with executive collapse cycles built into their condition, this is a designed-in failure mode.
**Be honest about weak claims.** Most "Duolingo streak research" is internal A/B-test marketing, not peer-reviewed. **Rejection sensitive dysphoria** as Dodson describes it is a clinical assertion lacking peer-review; cite **rejection sensitivity** (Downey & Feldman, 1996, *JPSP*) and **emotional dysregulation in ADHD** (Shaw et al., 2014, *Am J Psychiatry*; Beheshti et al., 2020 meta-analysis) instead. James Clear's "identity-based habits" is rhetorical synthesis; the underlying habit-identity correlation is mixed (Verplanken & Sui, 2019).
**Do.** Replace streaks with **non-quantified momentum**: a soft "you've been using Kon this week" indicator without numbers. Use brief reflection prompts (Frattaroli's 2006 expressive-writing meta gives modest but real effects, r ≈ 0.075–0.15) — never enforced. Offer implementation-intention coaching ("when X, then Y") which has d = 0.65 (Gollwitzer & Sheeran, 2006). Frame returns as fresh starts, not catch-ups. Where you must show progress, default to monthly or quarterly time-ranges, not daily.
**Avoid.** Streak counters. Streak-freeze monetisation. "Don't break the chain" framing. Public leaderboards. Badge systems contingent on consecutive use. Notifications triggered by inactivity.
### E. Notifications and nudges
**The evidence.** Kushlev, Proulx & Dunn (2016, CHI) showed that notifications alone produce significantly elevated ADHD-symptom scores in *non-ADHD* users — the implication for users already symptomatic is severe. Stothart et al. (2015) found even *receiving* a notification (without interaction) degrades attention. Mark et al. (2016, CHI) found longer email duration predicts higher measured stress (HR), and **batching does not reduce stress** in their data — but Fitz et al. (2019, *CHB*) RCT found three daily batches improved well-being over both as-they-arrive and total-disable. Pielot & Rello (2017) found total-disable increases anxiety and disconnection. The sweet spot is batching with user control.
**Calm Technology** (Weiser & Brown, 1995; Case, 2015) is a heuristic, not an empirically tested framework — Rogers (2006, UbiComp) critiques it directly. Use it for vocabulary; don't claim it as evidence. Mark's "23 minutes to refocus" figure is widely *mis*quoted — the original measured time to *return to* a task after intervening tasks, not full cognitive recovery. The strongest empirically grounded principle is Leroy's (2009) **attention residue**: unfinished tasks persist cognitively into the next.
The **nudge** literature is in the middle of a serious replication crisis. Maier et al. (2022, *PNAS*) re-analysed Mertens et al.'s positive meta-analysis using publication-bias correction and found **no overall evidence of reliable nudge effects**; DellaVigna & Linos (2022) found field nudges ~6× smaller than published academic nudges; Hu et al. (2025) second-order meta found d collapses from 0.27 to 0.004 after correction. **Don't over-promise behaviour change from copy tweaks.**
For sensory profile: Williams et al. (2021) on autism × hyperacusis (50–70% prevalence); Tomchek & Dunn (2007) — 95% of autistic children show atypical sensory processing.
**Do.** Default to **silent, batched, user-summoned** notifications. Offer 1–3 daily digest moments with user-set times. Use compassionate, behaviour-focused language that cues *guilt-repair* rather than *shame-withdraw* (Tracy & Robins, 2006; Breines & Chen, 2012). Honour OS quiet hours and sensory profile (text-only / haptic-only / silent variants). For time-blindness countermeasures (Barkley, 1997, 2001), externalise time visually (see Gaps).
**Avoid.** Push notifications by default. Red badges. "You haven't opened Kon in N days." Inactivity-triggered messages. "Should" or "must" language. Sound on by default. Sharp/high-frequency tones. Persuasive nudges presented as if behaviour-change-proven.
### F. Identity framing
**The evidence.** Phillips & Zhao's (1993) foundational AT-abandonment study found **29.3% of devices abandoned**, with non-involvement of users in selection and divergence between user goals and device logic among the strongest predictors. Scherer's Matching Person & Technology research (1998, 2005) shows uptake is predicted by mood, self-esteem, motivation, and **self-determination** as strongly as by feature-fit. Corrigan's self-stigma model (Corrigan & Watson, 2002; Corrigan, Larson & Rüsch, 2009) maps the awareness → agreement → application → harm cascade and the resulting "why try" effect. Bandura's (1997) self-efficacy work establishes that mastery experiences — not external validation — are the strongest builder of agency. The capability approach (Sen, 1999; Nussbaum, 2011; Toboso, 2011 applied to ICT; MacLachlan et al., 2025 ATA-C study) recommends evaluating tools by *what they let users do and be*, not by how close they bring users to a non-disabled norm.
The neurodiversity paradigm (Walker, 2021; Botha et al., 2024 — community-developed) argues against pathology framing. Shakespeare's (2006) sympathetic critique of the strict social model is also relevant: pure social-model framing under-recognises real cognitive limits the user experiences, which can itself feel invalidating.
**No RCT directly compares prosthetic vs training framings**, but the convergent evidence supports a clear hierarchy:
**Do.** Use **capability/scaffolding** language as primary: "Kon helps you do the things you want to do." Permit **prosthetic** framing for users who self-identify as disabled — "use it as long as you want, like glasses" — without imposing it. Show users their own work (reviewable transcripts, user-curated buckets) to build mastery experiences. Make it possible to use Kon forever without that feeling like failure.
**Avoid.** Cure/training framing ("graduate from Kon," "build your executive function"). Streaks framed as growth. Onboarding that pathologises ("Do you struggle with…?"). Marketing that implies the user is broken. Quizzes that diagnose. Any copy that implies success means needing Kon less.
### G. Gaps the literature surfaces
The most important Kon-relevant gaps are externalised time, body doubling, transition support, and structured implementation-intention scaffolding. Treated in detail in the next section.
---
## Gaps: features the literature suggests Kon should consider
**1. Externalised time visualisation.** Barkley's (1997, 2001) work establishes time as a *core* ADHD deficit (temporal myopia, time reproduction errors at long durations). Janeslätt et al.'s (2018) RCT of time-skill training plus Time Assistive Devices (visual timers, electronic schedules) — the strongest RCT evidence in this space — significantly improved daily time management. Kon currently captures, decomposes, and sorts but does not make time *visible*. A disappearing-disc visual on the active MicroStep, or an ambient "elapsed since started" indicator, would directly address the most-evidenced ADHD-specific scaffold. Avoid prescriptive Pomodoro cycles — Biwer et al. (2023, *BJEP*) found Pomodoro breaks *accelerated* fatigue and motivation loss vs self-regulated breaks.
**2. Body-doubling / co-presence layer.** Eagle, Baltaxe-Admony & Ringland's (2024, *ACM TACCESS*) survey of 220 neurodivergent participants — the first formal academic study of body doubling — found many users depend on it for basic activities. The mechanism is grounded in Zajonc's (1965) social facilitation (well-replicated for well-learned tasks). Evidence is emerging rather than strong: Lee et al.'s 2025 VR preprint suggests AI body doubles produce comparable outcomes to human ones. An async "I'm working too" presence layer, or scheduled silent-coworking sessions, fills a gap that solo capture/decomposition cannot.
**3. Implementation-intention coaching.** Kon decomposes into 3–7 steps but does not currently *phrase* them as implementation intentions. Gollwitzer & Sheeran's (2006) meta-analysis of 94 studies shows d = 0.65 for if-then planning; Gawrilow & Gollwitzer (2008) show it brings ADHD inhibition to non-ADHD level. Have the LLM generate at least one step in "when X, then Y" form, anchoring the action to an existing cue.
**4. Transition support and re-orientation.** Monsell (2003) on switch costs and Leroy (2009) on attention residue establish the cognitive cost of moving between tasks. Hume et al.'s (2021) third-generation EBP review classifies visual schedules as evidence-based for autism transitions. Kon should provide a brief "where was I?" re-orientation when returning to an interrupted MicroStep — a one-line summary of the last completed step plus the next one — and an optional gentle pre-warning before bucket switches.
**5. Coach/partner loop (optional).** Wilson et al.'s (2001, *JNNP*) NeuroPage RCT showed task-completion rose from 55% to 74% with paged reminders; Fish et al. (2008) found severe EF impairment moderates self-programming success — users with the deepest deficits benefit most when *someone else* sets the reminders. Janeslätt's RCT involved parent/teacher integration. An optional, granular sharing layer (single-task, time-bounded) for partners, coaches, or therapists addresses this without compromising local-first defaults. Frame as scaffold, not surveillance.
---
## Honest limitations
**Where the evidence is contested or absent, say so in the product, not just the docs.**
**Direct comparisons missing.** No RCT compares LLM-generated to therapist-generated task decomposition; goblin.tools and similar tools have not been peer-evaluated. No RCT compares local-first to cloud-stored journaling apps' effect on disclosure of stigmatised content — the case rests on transitive evidence from anonymity, privacy calculus, and chilling-effects literatures. No study isolates the Time Timer brand specifically; visual-timers-as-a-class have RCT support (Janeslätt, 2018).
**Popular concepts with weak empirical bases.** OpenDyslexic, Lexend, and Bionic Reading lack the evidence their marketing implies (Wery & Diliberto, 2017; Strukelj, 2024). Pomodoro is widely endorsed but Biwer et al. (2023) found self-regulated breaks outperform it. Tiny Habits / Fogg Behavior Model is a useful design heuristic with thin RCT support (Duarte et al., 2025 BMC scoping review). Calm Technology (Weiser & Brown) and "neuro-acoustic stimulation" (Brain.fm) are heuristics or industry-funded findings, not independently replicated science. Binaural beats have a positive meta (Garcia-Argibay, 2019, g=0.45) but later well-controlled studies on sustained attention are sceptical. The Mozart effect is debunked (Pietschnig et al., 2010). RSD as Dodson defines it is not peer-reviewed; rejection sensitivity (Downey & Feldman, 1996) and ADHD emotional dysregulation (Shaw et al., 2014) are. Spoon theory is a culturally legible metaphor (Miserandino, 2003) without psychometric validation; cite as communication frame, not clinical model.
**Replication caveats.** Sparrow et al.'s "Google effect" failed Many Labs replication. The doorway effect's specific magnitude is sensitive to task complexity (McKerracher et al., 2021) though event-boundary theory is robust. Mark's "23 minutes to refocus" is widely misquoted — it measured task return, not cognitive recovery. The nudge literature's overall effect collapses under publication-bias correction (Maier et al., 2022; Hu et al., 2025).
**Population gaps.** Most cognitive-offloading and dictation evidence generalises from healthy or LD populations. **ME/CFS, long COVID, fibromyalgia, perimenopausal cognitive symptoms, and depression-related cognitive impairment are essentially absent from the dictation, decomposition, and offloading literatures.** Most application to these groups is by extrapolation from TBI, ADHD, and autism research. Kon's design choices for these users are reasonable inferences, not validated interventions.
**Body doubling, AI decomposition for ADHD, LLM coaching for autism, and personalised acoustic ASR for dysfluency** are all areas where Kon could plausibly contribute primary evidence — well-designed in-app studies (with consent, opt-in, local analytics) would advance the field, not just the product. The honest framing for the developer to defend in public: "We've built Kon on the strongest available evidence; some of our choices are design intuition pending empirical validation; we will say which is which."

# Tiimo Competitive Intelligence Report (2026)
## Executive Summary: Kon's Key Advantages
Based on current intelligence, **Kon** has several immediate strategic openings against Tiimo:
1. **The "Lifetime" Opening:** Tiimo recently removed their highly popular lifetime license, causing massive frustration in the neurodivergent community (who often struggle with recurring subscriptions). Kon can win significant goodwill by offering a clear, sustainable lifetime tier or a radically different neuro-friendly pricing model.
2. **The Android/Platform Gap:** In September 2025, Tiimo completely removed its Android app, leaving a massive portion of the market unserved. They also lack a true native desktop application (relying on a web wrapper). Kon's native desktop-first approach fills a vital gap for users who need deep workflow integration rather than just a mobile companion.
3. **The Complexity Friction:** While Tiimo's AI Co-planner is popular, users report a steep learning curve and heavy setup time. Kon's voice-transcription premise—allowing users to simply speak to create structure—offers a dramatically lower barrier to entry for users with executive dysfunction.
## Executive Summary: Magnotia's Key Advantages
Based on current intelligence, **Magnotia** has several immediate strategic openings against Tiimo:
1. **The "Lifetime" Opening:** Tiimo recently removed their highly popular lifetime license, causing massive frustration in the neurodivergent community (who often struggle with recurring subscriptions). Magnotia can win significant goodwill by offering a clear, sustainable lifetime tier or a radically different neuro-friendly pricing model.
2. **The Android/Platform Gap:** In September 2025, Tiimo completely removed its Android app, leaving a massive portion of the market unserved. They also lack a true native desktop application (relying on a web wrapper). Magnotia's native desktop-first approach fills a vital gap for users who need deep workflow integration rather than just a mobile companion.
3. **The Complexity Friction:** While Tiimo's AI Co-planner is popular, users report a steep learning curve and heavy setup time. Magnotia's voice-transcription premise—allowing users to simply speak to create structure—offers a dramatically lower barrier to entry for users with executive dysfunction.
4. **B2B / Teams Vacuum:** Tiimo has virtually no enterprise or team-based pricing, focusing entirely on solo consumers (and a 5-person "family" sharing plan). This leaves the B2B neurodiversity-inclusion workspace wide open.

### Emotional intensity
Language consistently involves shame ("another thing I'm failing at"), resignation ("I've lost count"), and liberation when users find the right framing ("I wasn't broken — I was working with tools designed for someone else's operating system"). Anger directed specifically at subscription billing: one Effecto review reads "Pretty ironic that it's an app supposed to be ADHD-friendly yet charges you for a service you don't use." A Wisey Trustpilot review states: "They are unscrupulous and taking advantage of people with ADHD who may be less organised."
### Demand signals for Kon's specific features
### Demand signals for Magnotia's specific features
- **Voice-first capture** receives consistent praise wherever it appears — one user who deleted 47 apps kept a voice memo tool as one of three survivors.
- **Offline/local-first** positioning is an emerging differentiator; community responds positively to "your data stays with you."
- **One-time purchase preference** is acute: a Goblin Tools App Store reviewer wrote "The fact it isn't subscription-based is incredibly helpful — I know it's mine and can use it whenever I need, without having to worry about whether it's 'worth it' each month or if I'm going to forget to cancel."

# Kon Handover — 2026/04/19
# Magnotia Handover — 2026/04/19
*Originally written when the product was named Kon (and briefly Corbie); references rewritten in the 2026-04-30 rebrand sweep.*
Second dogfood sprint. Four phases: (1) fix bugs surfaced on first real use, (2) redesign History for cognitive-load hygiene, (3) resolve broken window resize/drag on Linux Wayland, (4) clean up microphone picker.
## What shipped this session
### Cross-window preferences sync
- `preferences.svelte.js` emits `kon:preferences-changed` Tauri event on update.
- `preferences.svelte.js` emits `magnotia:preferences-changed` Tauri event on update.
- Main / viewer / float layouts listen and call `applyExternalPreferences` without re-emit, so theme and font changes propagate live across sibling windows.
- Echo suppressed via source window label check.

- **Tags**: `$lib/utils/frontmatter.js` exposes `deriveAutoTags` (currently returns `[]`), `buildFrontmatter`, `serialiseFrontmatter`, `buildMarkdown`. Manual tags stored as `item.manualTags`, rendered as removable chips in the expanded row with `+ add tag` input.
- Header tag chip bar (cap 7, click to filter, × to clear), plus `tag:xyz` search syntax.
- Global **Starred** filter toggle in the History header.
- Research memo found all five previous auto-tag families redundant with existing row UI — kept the derivation hook for the post-Task-7 `topic:*` content tag from kon-llm.

### Viewer / editor popout
- `/viewer` route now reads `kon_viewer_mode` from localStorage ("view" | "edit").
- `/viewer` route now reads `magnotia_viewer_mode` from localStorage ("view" | "edit").
- Edit mode renders a plain textarea bound to `item.text`; 400ms debounced save flushes on input, final flush on `onDestroy`. Segment-specific controls (Compact, Starred) hidden in edit mode.
- Native title: **"Kon - Transcription Editor"**.

### Platform-aware window chrome (Linux fix)
**Root cause:** Tauri v2 frameless `decorations: false` on KDE Wayland + webkit2gtk does not honour diagonal corner resize (collapses `NorthEast` etc. to a single axis via GTK's `gtk_window_begin_resize_drag`), and `data-tauri-drag-region` adds noticeable drag latency. Setting `setPointerCapture` ahead of `startResizeDragging` does not help once the compositor has taken over the pointer grab. Verified via Context7 docs + Codex diagnosis — Linux frameless is a known-fragile path.
@@ -43,7 +45,7 @@ Second dogfood sprint. Four phases: (1) fix bugs surfaced on first real use, (2)
- Linux uses **native KWin/Mutter decorations**. `src-tauri/tauri.linux.conf.json` overlays `decorations: true` + full main window config (title, sizes) — overlays **replace** the windows array, so every field must be present, not just the delta. `src-tauri/src/commands/windows.rs` uses `cfg!(target_os = "linux")` to set decorations per window.
- macOS / Windows keep custom chrome. `src/lib/utils/osInfo.js` `isLinux()` gates `<Titlebar>` and `<ResizeHandles>` via `useCustomChrome = $state(false)`; flips to `!isLinux()` after `loadOsInfo()` resolves.
- Dueling drag-region handlers removed across Titlebar, float page, viewer page — everywhere a manual `startDragging()` lives, the `data-tauri-drag-region` attribute was deleted (they're alternatives per Tauri docs, not combinable).
- `ResizeHandles` kept for macOS/Windows frameless: 12 px edges / 20 px corners via CSS vars (`--kon-resize-edge`, `--kon-resize-corner`), `pointerdown` + `setPointerCapture`, corners with explicit higher z-index. Handles rendered as siblings of the animated layout div so `position: fixed` is viewport-relative rather than captured by the transform containing block.

## What's deferred
- **Transparent windows (`transparent: true`)** — Tauri issue #13270 reports this smooths drag/resize further on Linux, but it's moot now that Linux uses native decorations.
- **File-system export (.md save dialog)** — currently clipboard-only. Needs a Rust `write_text_file` command for plugin-less file writes.
- **Bulk select + bulk export** in History.
- **LLM-powered content tags** (`topic:*`, `intent:*`) — slots into Task 7 `kon-llm` stub once Phase 3 wires real llama-cpp-2.

- **Settings UX overhaul** — Jake flagged that current settings feel overwhelming. Proposed: bunch high-traffic settings, hide advanced behind a toggle. Brainstorm + plan deferred to a dedicated session.
- **Task 7 (MicroSteps end-to-end)** — storage + Tauri CRUD + kon-llm stub + frontend dual-write all landed in an earlier commit chain. The MicroSteps UI was written as the final task 7 step but not yet dogfooded against the stub LLM. Needs manual walkthrough.

*Originally written when the product was named Kon (and briefly Corbie); references rewritten in the 2026-04-30 rebrand sweep.*
Phase 8 session. Executed the forgiving-gamification spec + plan written at the top of the session against `main`. Shipped 14 commits end-to-end. All automated gates clean; manual dogfood walkthrough still owed when Jake next opens the running app.
## Rebrand note
Product rename **Kon → Corbie** still in flight. Copy in new docs is "Corbie"; codebase paths / package names / repos still carry `kon`. No rebrand work this session. See `~/.claude/projects/-home-jake-Documents-CORBEL-Main/memory/project_corbie_rebrand.md`.
Product rename **Magnotia → Magnotia** still in flight. Copy in new docs is "Magnotia"; codebase paths / package names / repos still carry `magnotia`. No rebrand work this session. See `~/.claude/projects/-home-jake-Documents-CORBEL-Main/memory/project_magnotia_rebrand.md`.

- **`serde` is now a dependency of `kon-storage`.** Added because `DailyCompletionCount` is serialised directly to the frontend via Tauri. The existing `TaskRow` → `TaskDto` split wasn't reused because the struct has no camelCase translation need (`day`, `count` are already frontend-friendly). Simpler, one fewer file to maintain.

The existing `TaskRow` → `TaskDto` split wasn't reused because the struct has no camelCase translation need (`day`, `count` are already frontend-friendly). Simpler, one fewer file to maintain.
- **`$derived` cannot be exported at module scope in `.svelte.ts`.** Svelte 5 errors with `derived_invalid_export`. Originally hit during Task 9 integration; fix landed in the same commit (`3cadbb0`). `svelte-check` misses this; only Vite catches it. Plan/spec both mistakenly prescribed `$derived`; future stores should use `export function fooCount(): number` + `(...)` call sites, or a `$derived` wrapped inside a component script.
- **Tuple `FromRow` in storage.** `kon-storage` strips sqlx's `derive` feature, so `#[derive(sqlx::FromRow)]` is not available. Use tuple `FromRow` `(String, i64)` etc. instead. Noted for future tasks in this crate.
