From 7b9785a91e98b07543b630e31c567cafd75069b3 Mon Sep 17 00:00:00 2001 From: Dano Morrison Date: Mon, 6 Jul 2026 18:00:22 -0700 Subject: [PATCH 01/29] =?UTF-8?q?Fix=20broken=20Clean=E2=86=92Analyze=20ro?= =?UTF-8?q?und-trip:=20persist=20cleaned=20epochs=20to=20host=20disk?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The "Clean Data" flow told Pyodide to `raw_epochs.save("")`, but the worker's filesystem is MEMFS (in-memory) and cannot reach host disk — so the cleaned `-epo.fif` never landed on disk and the Analyze screen's `readWorkspaceCleanedEEGData` picker found nothing in a fresh workspace. This repairs that flow with a MEMFS→host write-back bridge, the one slice the epoch-review plan (§6d / Open Question 8) declares resolved and standalone. Chain: Python saves to MEMFS `/tmp/-cleaned-epo.fif` → the worker reads the bytes and posts them back zero-copy (transferable ArrayBuffer) on a new `savedEpochs` dataKey → `pyodideMessageEpic` writes them to `Data//EEG/-cleaned-epo.fif` via a new `fs:writeCleanedEpochs` IPC channel that mirrors `fs:storePyodideImagePng`. - src/main/index.ts: new `fs:writeCleanedEpochs` handler (binary renderer→disk write) - src/preload/index.ts + electron.d.ts: `writeCleanedEpochs` bridge + type - webworker.js: `readFileAfter` read-back path posts MEMFS bytes as a transferable - webworker/index.ts: `saveEpochs(worker, subject)` now saves to MEMFS (overwrite=True) and requests read-back - pyodideEpics.ts: route `savedEpochs` → `writeCleanedEpochs`, with a success/error toast Output path is bit-identical to what the Analyze picker globs (`epo.fif` suffix).

This unblocks the pipeline without the bigger refactor. The deeper latent issue remains, though: `worker.postMessage` returns `undefined` on *post*, so the `await`s in `webworker/index.ts` are no-ops and cross-message sequencing still relies on worker FIFO. A true `runPython(worker, code, ctx?)` RPC — `Map` + one `message` listener, worker echoes `id` — would let epics `await` real results and delete the `plotKey`/`dataKey` switch entirely. Only worth doing if the FIFO sequencing ever actually bites; not urgent now. - [ ] Pyodide-fidelity smoke test — analysis pipeline is tested against native MNE, not yet under Pyodide/WASM (see `.llms/learnings.md`). **In progress:** the epoch-review Phase 0 (see `docs/epoch-review-ui-plan.md` §0) adds a *narrow* Pyodide test for the `get_epochs_arrays` float32 buffer path (byteLength, decode-vs-native, transfer detaches source); the full-pipeline Pyodide job remains deferred. - [ ] Pre-existing TypeScript errors (not regressions): `experimentEpics.ts` (RxJS operator types), `routes.tsx` (Redux container prop types). +- [ ] **Epoch reviewer Phase 2 polish (from PR #225 review).** Three non-blocking behaviors flagged during the Phase 2 forge: (1) `get_epochs_arrays`/`suggest_rejections` use `pick_types(eeg=True)` whose MNE default is `exclude='bads'`, so after a Clean that flags a bad channel the re-fetched reviewer omits that channel from the display (saved `.fif` is unaffected) — decide whether to keep bad channels visible-but-greyed (`exclude=[]`) instead of vanishing; (2) re-running "Auto-flag" with the same threshold re-adds suggestions the user had manually unclicked (additive union merge in `CleanComponent.componentDidUpdate`); (3) the auto-flag threshold `` has no min guard (0 µV flags everything).

Note: this file also carries in-progress epoch-reviewer Phase 2 Clean-screen changes that were already staged in the working tree; they are committed here because they could not be separated non-interactively. The T2 guard is the handleCleanData method + its wiring. QA plan 6e/9b (T2).

This is the normal skin-conductance / electrode settling +artifact that resolves after the electrodes sit on the head for a bit — but a +first-time user has no way to know that. Reads as "broken / bad device." + +**Where it lives:** +- Signal-quality color is std-dev based, per channel: + `src/renderer/utils/eeg/pipes.ts` (`parseMuseSignalQuality`) maps std → GREAT/OK/BAD/DISCONNECTED. + Thresholds `src/renderer/constants/constants.ts` `SIGNAL_QUALITY_THRESHOLDS` + (BAD ≥ 15, OK ≥ 10, GREAT ≥ 1.5). At settling, std is high → everything BAD (red). +- Rendered by `SignalQualityIndicatorComponent.tsx` (head diagram fill) and the raw + trace in `ViewerComponent.tsx`. +- Screen: `EEGExplorationComponent.tsx` (also gates the pre-connect vs connected view). +- Same red-on-settle problem almost certainly shows in the **connect / pre-test flow** + (`CollectComponent/ConnectModal.tsx`, `PreTestComponent.tsx`) — check there too. + +**Proposed fix shape (decide in impl session):** +- Add a settling window: track time-since-connect; for the first ~30–60s show a + friendly banner/overlay ("Electrodes are settling — red is normal for the first + minute while the sensors make contact.

Heavier: an explicit `SETTLING` signal-quality state + derived from time-since-connect that suppresses BAD styling early on. +- Keep the honest state reachable — if it's *still* red after the window, that's a real + bad-contact signal and should surface. + +**Open question:** settle window length, and whether "settling" is time-based only or +also "std is trending down." Product-shaped — likely a quick /office-hours call. + +--- + +## 2. Explore EEG: raw trace rendering is chunky / stutters + +**Observed:** the scrolling EEG trace stutters and looks chunky. Long-standing, not new. +Suspected to be the SVG line-drawing approach. + +**Where it lives:** +- Trace renders inside a bundled `<webview>` page driven by + `src/renderer/components/d3Classes/EEGViewer.js` — d3 into an **SVG `<path>`** + (`append('path')`, line 188), with `downsampling = 2` and `simplify-js` on incoming + epochs. Host component: `ViewerComponent.tsx` (feeds epochs to the webview). +- Redrawing/growing SVG paths every plotting interval is the likely stutter source + (SVG path re-layout, not GPU-accelerated). + +**Proposed fix shape (decide in impl session):** +- Cheapest first: profile whether the jank is redraw cost vs. epoch cadence. Tune + `downsampling`, `simplify-js` tolerance, and the d3 transition/`plottingInterval` + before any rewrite. +- If SVG is genuinely the ceiling: swap the trace to `<canvas>` (2D) or WebGL. Note the + epoch-review reviewer has the *same* SVG-vs-WebGL tension logged (see + `docs/epoch-review-ui-plan.md` OQ1 / TODOS Phase 4 `drawEpochs`) — worth solving both + with one rendering approach rather than twice. + +**Ponytail flag:** don't jump to WebGL first. Profile + tune the existing SVG path; only +rewrite if measurement says SVG is the wall. + +--- + +## 3. Generalize the signal-quality help content + surface it on Explore EEG + +**Observed:** the Collect screen already has good signal-quality explanation content, +but the tips are written for the **old Emotiv device** and only exist on Collect. This +should be (a) generalized to be device-agnostic and (b) also shown on the Explore EEG +screen. Ties into #1 — the settling explanation and these tips are the same "help me +get a good signal" surface. + +**Where it lives:** +- Content + stepper: `src/renderer/components/CollectComponent/HelpSidebar.tsx` + (`HELP_STEP` enum + `renderHelpContent`). Exports `HelpSidebar` (full panel) and + `HelpButton` (toggle). +- Mounted only in the Collect flow: `CollectComponent/PreTestComponent.tsx` + (lines 125–168). `HelpButton` alone also appears in `AnalyzeComponent.tsx:514`. +- **Not present** on Explore EEG (`EEGExplorationComponent.tsx`) — that's the gap. +- File already carries a TODO: *"Refactor this into a more reusable Sidebar component + that can be used in Collect, Clean, and Analyze screen"* — this item cashes that in. + +**Emotiv-specific content to fix (device-agnostic rewrite):** +- `HELP_STEP.SIGNAL_SALINE` — "Saturate the sensors in saline" is Emotiv gel/saline-cap + language.

Collect "Run Experiment" landing — ugly, wastes space, redesign + +**Observed (step 2 COLLECT, pre-run landing):** the screen looks poorly designed.

Wants efficient use of space. + +**Where it lives:** `src/renderer/components/CollectComponent/RunComponent.tsx` +(the `!isRunning` branch, lines 102–134). + +**Concrete problems found in the markup:** +- **The "empty input bar" is actually the edit button.** Line 106–112: + `<button className="flex justify-end w-full">✏</button>` — a full-width button holding + only a right-aligned pencil emoji. It renders as an empty full-width bar that reads as + a broken/empty text field. Should be a small icon button beside the title or the + subject metadata, not a `w-full` bar. +- **Metadata is unstyled stacked text** (Subject ID / Group Name / Session Number) — + no card, no grouping, weak hierarchy. +- **`Run Experiment` is `w-full`** (line 125) — oversized primary action. +- **Everything is top-left with a vast empty lower half** — no layout using the space + (e.g. centered card, or a two-column with device/signal status). +- **Redundant nested wrapper:** the outer `<div>` (line 97) *and* the inner `!isRunning` + `<div>` (line 103) both set `h-screen p-[3%] bg-gradient-to-b …` — double gradient + + double screen-height padding. Cheap cleanup, collapse to one. +- **Title duplicates the nav breadcrumb** — `<h1>{title}</h1>` repeats + "Faces_and_Houses" already shown in the top nav dropdown. Consider dropping or + repurposing. + +**Proposed fix shape:** +- Rebuild as a compact centered card: title (or drop it), a clean subject/group/session + summary block with a small inline edit (pencil) affordance, a right-sized primary + "Run Experiment" button. Fill the space intentionally (center the card, or add + device/signal-quality status alongside so the operator confirms readiness before run). +- Collapse the redundant `h-screen`/gradient wrapper. +- Design-shaped — worth a `/design-review` or `/design-consultation` pass in the impl + session rather than eyeballing spacing. + +**Ponytail:** this is one small component. Don't introduce a layout system — a single +centered `Card` (shadcn `Card` already exists) + right-sized button covers it. + +## 5. No forward breadcrumb after finishing a run — flow dead-ends on Collect + +**Observed:** completed the experiment and landed back on the same "Run Experiment" +screen. Nothing indicates the run is done or points forward to Clean. The only way to +advance is the top workflow nav (3 CLEAN) — undiscoverable for a first-timer; the flow +dead-ends. + +**Where it lives:** +- Run finish path: `RunComponent.tsx` `onFinish` → `ExperimentActions.Stop({data})` + (line 89–94). When `isRunning` flips false, it re-renders the *same* pre-run landing + (the `!isRunning` branch, line 102) — there is **no post-completion state**. It looks + identical to before the run, so "did it even record?" is unclear too. +- Forward nav today: the workflow steps in + `src/renderer/components/SecondaryNavComponent/index.tsx` (`onStepClick` per step) → + Clean route is `SCREENS.CLEAN.route` (`routes.tsx`, `constants.ts`). That's the only + COLLECT→CLEAN path. + +**Proposed fix shape:** +- Give `RunComponent` a distinct **post-run / completion state** (track "a run finished + this session", e.g. off the `Stop` result / recorded file) that: + - confirms the recording succeeded (filename, trial/marker count if cheap), and + - shows a primary **"Clean your data →"** CTA that navigates to `SCREENS.CLEAN.route` + (reuse the same routing the secondary nav step uses), plus a secondary "Run again." +- This is the same "guide the operator to the next step" gap that #4's redesign touches + — do them together in the Collect/Run pass. + +**Ponytail:** don't build a wizard. One completion panel with a "Clean your data →" +link-button (react-router `Link` is already imported in `RunComponent`) closes the gap. + +## 6. Clean screen — multiple issues (layout, labels, viewer, and a real units bug) + +**Screen:** `src/renderer/components/CleanComponent/index.tsx` (+ `webworker/utils.py`). +Dano's walkthrough surfaced four UX asks plus, on auto-flag, a genuine data bug. + +### 6a. Settings gear icon is mis-sized +The ⚙︎ auto-flag settings button (`CleanComponent/index.tsx` ~line 352–359) looks +too-big / not-big-enough next to "Clean Data" and "Auto-flag artifacts". Size it to +match the adjacent buttons (icon-button sizing / same height). + +### 6b. Condition labels show STIMULUS_1 / STIMULUS_2 instead of real names (Faces, Houses) +Counts, legends, and the ERP all read "STIMULUS_1 / STIMULUS_2". Should show the +experiment's real condition names ("Faces", "Houses"). +- Source of the generic labels: `src/renderer/utils/eeg/markerRegistry.ts` — + `CODE_TO_LABEL` is hard-coded `STIMULUS_1..4` (deliberately "condition-neutral"). + `buildMarkerRegistry` only ever emits those. +- Fix shape: let the registry derive a human label from the experiment's stimulus + metadata (per-experiment code→name map, e.g. Faces_and_Houses: 1→Faces, 2→Houses), + falling back to `STIMULUS_n` when unknown. Keep the numeric code contract intact + (labels are display-only; codes still drive CSV + MNE `event_id`). Thread the real + label into the Clean counts/legend/ERP. +- Ponytail: don't build an i18n/label system — a per-experiment `{code: name}` map on + the experiment object, read by `buildMarkerRegistry`, covers it. + +### 6c. Epoch viewer is too small and renders poorly +The Epochs panel gets too little real estate and the traces render badly (same +SVG-trace rendering concern as #2). Ties to the epoch-reviewer WebGL/`drawEpochs` +question already logged (`docs/epoch-review-ui-plan.md` OQ1, TODOS Phase 4). + +### 6d. Re-layout to prioritize Epochs + add a reject-onboarding flow +Give the Epochs viewer much more space, and preempt an onboarding flow that teaches +students how to read epochs and reject bad ones. **This is already scoped** as +**Epoch reviewer Phase 3 — onboarding layer** in TODOS.md (plain-language epoch/artifact +explanations, guided mode, channel legend tied to head position). This walkthrough is +direct evidence for prioritizing it. Route the product questions (onboarding depth, +guided-mode-as-default — TODOS OQ3) through /office-hours or /plan-ceo-review. + +### 6e. 🔴 BUG: Auto-flag rejects ALL epochs — µV→V units error (NOT threshold too low) +**Observed:** "Auto-flag artifacts" flagged all 16/16 epochs → ERP averages over 0 +epochs (blank). Flag reasons: **peak-to-peak 65,715,724 µV / 66,228,063 µV / +89,980,195 µV**. Dano's read was "thresholds too low"; the real cause is deeper. + +**Root cause (grounded):** 65 million µV = ~65 **volts** peak-to-peak is physically +impossible for EEG (real Muse ptp is tens of µV; the amp rails well under 1 mV). The +value is inflated ~1e6×: +- `webworker/utils.py` `load_data` (lines ~90–95) builds `RawArray(data=data, …)` + straight from the CSV values with **no µV→V scaling**. MNE treats EEG channel data as + **volts**, but the Muse CSV is in **µV**. So a real ~65 µV excursion is loaded as + ~65 "volts". +- `suggest_rejections` (utils.py ~line 350–359) computes ptp in MNE's unit (thinks + volts) then `* 1e6` to report µV → 65 → 65,000,000 µV. Threshold default + `DEFAULT_PTP_THRESHOLD_UV = 100` (`constants.ts:12`) → `thresh_v = 1e-4 V`, but ptp is + ~65 in MNE units, so **every** epoch exceeds it. + +**Fix shape:** scale CSV µV → V on load in `load_data` — multiply the **eeg** channels +by `1e-6` before/at `RawArray` (do NOT scale the last `stim`/Marker channel; markers are +numeric codes — see `.llms/learnings.md`). After the fix, ptp ≈ 65 µV, the 100 µV +default behaves sanely, and auto-flag stops nuking everything. **Verify against the +golden test** (`tests/analysis/test_erp_roundtrip.py`) — a global scale factor won't fail +its relative-amplitude assertions, so add an absolute-µV sanity check so this can't +regress silently.

Likely a DOM/SVG/input attribute being set to `NaN` — plausibly the epoch +viewer or the `amp`/threshold `<input>` receiving `NaN`.

Auto-flag threshold: slider with device presets, not a raw µV number input +**Observed:** the threshold is a bare absolute-µV number `<input>` — students have no +idea what number to type. Make it a streamlined **slider** with sensible values +**pre-selected per device** (Muse vs Neurosity vs external LSL), so users adjust +sensitivity intuitively instead of guessing microvolts. + +**Where it lives:** `CleanComponent/index.tsx` — `autoFlagThreshold` state (default +`DEFAULT_PTP_THRESHOLD_UV = 100`, `constants.ts:12`) rendered as a numeric `<input>` in +the auto-flag settings panel (~lines 369–378); parsed in the `!Number.isNaN` handler +(~line 206–213). shadcn has no Slider yet — add `@radix-ui/react-slider` (same family as +the already-installed Select) or a styled native `<input type="range">`. + +**Fix shape:** +- Replace the number input with a slider (labeled low/high sensitivity, showing the + current µV under the hood but not requiring users to reason in µV). +- Seed the default + range from the connected device — a per-device preset map + (reasonable ptp ceilings differ by hardware). Fall back to `DEFAULT_PTP_THRESHOLD_UV`. +- **Depends on 6e:** presets are only meaningful once the µV→V units bug is fixed — + otherwise "100 µV" doesn't correspond to reality. Sequence 6e before tuning presets. + +**Ponytail:** a native `<input type="range">` + a small `{device: {min,max,default}}` +map covers this — no slider component library required unless the design calls for it. + +## 7. EEG disabled by default + no warning when running without EEG + +**Observed:** ran an experiment with EEG not connected, was **not notified**, and found +"Enable EEG" was **off by default** — nonsensical for an EEG app. Result: a run that +records behavior but no brain data, silently. + +**Where it lives:** +- Default: `src/renderer/reducers/experimentReducer.ts:38` — initial state + `isEEGEnabled: false`. Toggled via `SetEEGEnabled` (`experimentActions.ts:38`); the + toggle UI is the "Enable EEG" switch in `SecondaryNavComponent` SettingsDropdown + (wired from the workflow screens, e.g. `DesignComponent`). +- Cascade when `isEEGEnabled === false`: + - `CollectComponent.componentDidMount` skips auto-connect (only connects if EEG on). + - `RunComponent`: `isRunComponentOpen` initializes to `!isEEGEnabled` → opens straight + to the Run screen, bypassing connect/pre-test. + - `RunComponent.eventCallback` gates on `isEEGEnabled` → **no markers injected**, so + even if a device were streaming, this path wouldn't tag events. + - Net: no device, no markers, no warning — the operator only finds out later (empty + EEG, e.g. the Clean screen). + +**Proposed fix shape:** +- **Flip the default to `isEEGEnabled: true`** (one line in `experimentReducer.ts`). + EEG-on is the app's whole point; opt *out* for the behavior-only case, not opt in. +- **Warn before a no-EEG run.** When starting a run with EEG enabled but no device + connected — or with EEG disabled — surface a clear confirm ("EEG is not connected — + this run will record responses but no brain data. Continue?"). `RunComponent`'s + `handleStartExperiment` already does a `showMessageBox` confirm for file-overwrite; + reuse that pattern for the no-EEG case. +- Consider persisting the user's EEG-enabled choice rather than resetting per session. + +**Ponytail:** the default flip is one line; the guard is one extra `showMessageBox` +branch in the existing `handleStartExperiment`. No new state machine needed. + +## 8. Remove the "Insert the USB Receiver" modal step (Emotiv-era, irrelevant for Muse) + +**Observed:** the connect flow still has an "Insert the USB Receiver" step. Muse is +Bluetooth — no dongle. Remove it. + +**Where it lives:** `src/renderer/components/CollectComponent/ConnectModal.tsx`. +Local `enum INSTRUCTION_PROGRESS { SEARCHING, TURN_ON, COMPUTER_CONNECTABILITY }` +(line 42). Flow: `TURN_ON` ("headset on & charged") → **`COMPUTER_CONNECTABILITY`** +("Insert the USB Receiver", lines ~260–293) → `handleSearch()` → device list. + +**Exact removal (trivial, ready to implement):** +1. Delete the `COMPUTER_CONNECTABILITY` render block (lines ~260–293). +2. In the `TURN_ON` step, change **Next** (lines ~245–255) from + `handleinstructionProgress(INSTRUCTION_PROGRESS.COMPUTER_CONNECTABILITY)` to call + `this.handleSearch` directly (what the USB step's Next did) — so "headset on" flows + straight to searching. +3. Remove `COMPUTER_CONNECTABILITY` from the enum. +4. Leave the device-list "Back" / "Don't see your device?" targets (`…Progress(1)` = + `TURN_ON`) as-is — still valid. + +**Note:** this is small and low-risk — a good candidate to just land in the impl session +(clean tree → one atomic commit). No product decision needed. + +## 9. Analyze screen empty after Clean→Analyze + "Go to Folder" broken (two real bugs) + +### 9a. 🔴 BUG: "Go to Folder" on Home does nothing — relative path to shell API +**Observed:** the "Go to Folder" button on the Home screen doesn't open the workspace, +blocking any manual check of what was written. + +**Root cause (grounded):** `src/renderer/utils/filesystem/storage.ts:29` +``` +openWorkspaceDir = (title) => api().showItemInFolder(path.join('BrainWaves_Workspaces', title)) +``` +passes a **relative** path `"BrainWaves_Workspaces/<title>"` to +`shell.showItemInFolder` (`src/main/index.ts:159`). `shell.showItemInFolder` requires an +**absolute** path — given a relative, non-existent one it silently no-ops. The real +workspace dir is absolute: `path.join(os.homedir(), 'BrainWaves_Workspaces', title)` +(`main/index.ts:116–118`, `getWorkspaceDir`). Called from +`HomeComponent/index.tsx:250`. + +**Fix shape:** resolve the absolute path in main, not the renderer. Add a +`shell:openWorkspaceDir` handler that does `shell.openPath(getWorkspaceDir(title))` +(opening the folder is better UX than `showItemInFolder`, which highlights the item in +the parent). Point `openWorkspaceDir` at it. Removes the relative-path guesswork and the +duplicated `'BrainWaves_Workspaces'` literal. Small, isolated fix. + +### 9b. 🔴 BUG: Analyze "Select Clean Datasets" is empty after cleaning +**Observed:** cleaned the dataset, clicked Analyze, and the "Select Clean Datasets" +picker is empty — nothing to analyze. + +**Grounding — the write/read paths MATCH, so the file wasn't written (not a scan miss):** +- Write: `fs:writeCleanedEpochs` (`main/index.ts:332`) → + `<workspace>/Data/<subject>/EEG/<subject>-cleaned-epo.fif`. +- Read: `fs:readWorkspaceCleanedEEGData` (`main/index.ts:246`) scans the workspace + recursively for the `epo.fif` suffix — `-cleaned-epo.fif` matches. So the picker would + list the file **if it existed**. Empty ⇒ no cleaned `.fif` on disk. +- Save trigger: the worker must emit a `dataKey === 'savedEpochs'` message with a buffer; + only then does `pyodideEpics.ts:129–145` call `writeCleanedEpochs` (+ "Cleaned data + saved" toast). If that message/buffer never arrives, nothing is written and nothing + errors. + +**Two suspects for the impl session (verify, don't assume):** +1. **Consequence of the units bug (6e):** on this run auto-flag had marked **all 16/16 + epochs** for rejection. If Dano clicked "Clean Data" with everything flagged, the drop + removes every epoch → the saved Epochs object is **empty**, which may fail to write a + valid `.fif` (or write a degenerate one that the scan/parse skips) — with no user- + facing error. Fix 6e first, then re-test a normal clean (few rejections). Also: **guard + against cleaning to zero epochs** (warn / block "Clean Data" when the drop set == all + epochs) so a student can't silently destroy their dataset. +2. **The known worker-RPC FIFO fragility** (see `.llms/learnings.md` / TODOS "Full Pyodide + worker RPC"): `worker.postMessage` awaits are no-ops, so the drop→save→re-fetch + sequence relies on FIFO ordering. If the save step's buffer is dropped/empty, the + `savedEpochs` branch silently writes nothing. Add an explicit failure surface — if + `savedEpochs` never arrives (or arrives empty), toast an error instead of failing + silent. + +**Common thread with the whole walkthrough:** silent failure. Collect ran with no EEG and +no warning (#7); auto-flag nuked everything from a units bug (#6e); cleaning to zero +epochs produced an unanalyzable dataset with no error here.

The existing epic shape stays the same — just add conditionals. - -5. **`lslForwardEpic` already handles Neurosity** because it reads `deviceType` from Redux state and passes it through to `LSLEpoch`. The outlet manager creates a separate outlet per `deviceId`. - -6. **Test:** simultaneous Muse + Neurosity streams visible in LabRecorder. - ---- - -### Phase 3: LSL Inlet Manager + External Device Visualization - -**Goal:** Users can discover and visualize any LSL stream on the local network (OpenBCI, g.tec, BrainFlow, pylsl test scripts), even without a BLE device. - -**Steps:** - -1. **Create `src/main/lsl/inlets.ts`** with `LSLInletManager` (discover, subscribe, poll, forward). - -2. **Wire inlet IPC handlers** in `src/main/index.ts`: - - `ipcMain.handle('lsl:discoverStreams', ...)` → returns `DiscoveredStream[]` - - `ipcMain.on('lsl:subscribeStream', ...)` → starts poll loop, sends `lsl:inletData` - - `ipcMain.on('lsl:unsubscribeStream', ...)` → stops poll loop - -3. **Add inlet IPC to preload** (`subscribeLSLStream`, `unsubscribeLSLStream`, `onLSLInletData`). - -4. **Build a stream discovery UI** — add a new tab or section in `ConnectModal.tsx` for "External LSL Device". It calls `discoverLSLStreams()`, shows results, and lets the user subscribe. - -5. **Add `LSL = 'LSL'` to `DEVICES` enum** and add a new Redux action `SetLSLInletStream` that stores the `DiscoveredStream` info in `deviceReducer` as the `connectedDevice`. - -6. **Wire inlet data to `rawObservable`** — when an inlet is subscribed, create an RxJS Subject in the renderer that emits `EEGData` for each `lsl:inletData` message, then dispatch `SetRawObservable` with it. Signal quality viz will work automatically. - -7. **Test with BrainFlow or `pylsl`** test sender script. - ---- - -### Phase 4: Stimulus Markers via LSL - -**Goal:** lab.js experiment events appear as a dedicated Markers stream in LabRecorder, aligned with the EEG stream. - -**Steps:** - -1. **Create the marker outlet** in `LSLOutletManager`: - - `StreamInfo`: name `'BrainWavesMarkers'`, type `'Markers'`, 1 channel, `IRREGULAR_RATE`, format `string` - - Create on app startup (not per-device) - -2. **Wire `lsl:sendMarker` IPC handler** in `src/main/index.ts` → calls `lslOutlets.pushMarker(label)`. - -3. **Update `RunComponent.tsx`** to call `window.electronAPI.sendLSLMarker({ label: event, rendererTimestamp: performance.now() })` alongside the existing `injectMuseMarker(event, time)` call. - - Keep `injectMuseMarker` — it embeds markers in the raw EEG CSV, which the existing Pyodide analysis pipeline depends on. - -4. **Implement clock sync** (optional, needed if sub-5ms precision required): - - Periodically send a round-trip IPC ping: renderer records `t0 = performance.now()`, main records `lsl_local_clock()`, renderer records `t1`. Offset ≈ `lsl_local_clock() - (t0 + t1) / 2`. - - Store offset in a ref; pass it in `LSLMarker` so main can correct the LSL timestamp. - - For most ERP paradigms, raw IPC jitter (1–5ms) is acceptable and this step can be deferred. - -5. **Test:** run Stroop or N170 experiment with LabRecorder, load XDF in MNE Python, verify marker latencies align with EEG epochs. - ---- - -### Phase 5: Production Hardening - -- **Backpressure for high-density inlets**: for 64+ channel streams at 1kHz+, decimate in main before forwarding to renderer. Full-rate stays on LSL network for LabRecorder. -- **Graceful error handling**: BLE disconnects, LSL network loss, inlet timeouts, `node-labstreaminglayer` FFI errors. -- **Platform testing**: macOS arm64, macOS x64, Windows x64. Confirm liblsl binary path resolves correctly post-packaging. -- **Electron packaging verification**: `npm run package`, install the `.dmg`/`.exe`, run with LabRecorder. -- **Linux Web Bluetooth**: `--enable-experimental-web-platform-features` is already set in `src/main/index.ts:23`. Verify BLE works end-to-end on Ubuntu. - ---- - -## Risks and Mitigations - -| Risk | Severity | Mitigation | -|---|---|---| -| `node-labstreaminglayer` is low-traffic (~7 downloads/week) with possible undiscovered Electron-specific bugs | Medium | Pin version. Test Phase 1 against real hardware before building further. If FFI proves unstable, fallback: Python sidecar process using `pylsl` with a WebSocket bridge. | -| liblsl binary path breaks after electron-builder packaging (ASAR) | High | Add `asarUnpack: ["**/*.node"]` in Phase 1. Test packaged build early — don't leave this for Phase 5. | -| IPC marker jitter exceeds tolerance for ERP analysis | Low | Document typical jitter (1–5ms). Add clock sync in Phase 4 if needed. | -| `@neurosity/sdk` Web Bluetooth API changes or breaks | Medium | SDK is MIT; fork if needed. Crown BLE protocol is documented. | -| High-channel-count LSL inlets (64ch, 1kHz) overwhelm renderer | Medium | Decimate in main process in Phase 5. | -| iOS / mobile pivot requires native BLE | Low (deferred) | Adapter pattern in `muse.ts` / `neurosity.ts` isolates BLE.

Release workflow: - New 'verify' job (test + typecheck + lint) that the publish matrix depends on. Nothing builds or uploads until it is green. - Split 'package-ci' into build -> verify artifacts -> publish, so a build with a missing Pyodide payload cannot be published. - npm ci, and fail-fast so a broken tag uploads as few half-good artifacts as possible across the three OS legs. test.yml: npm ci, plus the artifact check after Build. package.json: publish.releaseType 'draft'. electron-updater is wired to this repo, so a tag would otherwise push an update to installed clients the moment it built. Draft means artifacts are uploaded but a human publishes. New tests: - tests/pyodideAssets.test.ts — static guard on the contract between extraResources ('to': pyodide) and the main process protocol handler (path.join(process.resourcesPath, 'pyodide')), plus the dev-side path and the directory InstallMNE writes into. These live in three files with no shared constant; a mismatch is invisible in dev and broke prod completely once (see .llms/learnings.md). Needs no build, so it runs in the default suite. - tests/build.test.ts — post-build presence checks: the three bundles, the Pyodide runtime files, and every wheel named in the package manifest. Runs via 'npm run test:build' under its own config and is excluded from the default run, so a missing build is a loud ordering error, never a silent skip.

This unblocks the pipeline without the bigger refactor. The deeper latent issue remains, though: `worker.postMessage` returns `undefined` on *post*, so the `await`s in `webworker/index.ts` are no-ops and cross-message sequencing still relies on worker FIFO. A true `runPython(worker, code, ctx?)` RPC — `Map<id,{resolve,reject}>` + one `message` listener, worker echoes `id` — would let epics `await` real results and delete the `plotKey`/`dataKey` switch entirely.

Suggestions **pre-mark** epochs in the reviewer and are - fully **overridable**; the actual drop still goes through the Phase-1 - `apply_rejection` path so the saved `.fif` stays MNE-exact. -- **OQ5 (bad channels on low-channel devices) → enabled everywhere, with a guard.** - Click a channel label to toggle it bad; bad channels flow to `apply_rejection`'s - `bad_channels` param (already built in Phase 1).

Vision - -Replace MNE's native Matplotlib "clean epochs" GUI — which **cannot run in the -Pyodide/WASM port** — with a first-class, fully interactive React experience for -reviewing and cleaning epoched EEG. - -This is not just a feature port. It is a chance to make epoch review **an -onboarding experience to EEG signal analysis** as much as a tool. The target -user is a student who may be seeing epoched EEG for the first time. The UI should -teach *what an epoch is, what artifacts look like, and why we reject them* while -they do the work — in the app's lighthearted, student-friendly voice (per -`.llms/CLAUDE.md`). It must also be a genuinely capable tool an experienced user -trusts. Both, not either. - -It should be **fully featured and interactive** — at least at parity with what -MNE's GUI offered, and ideally beyond it (guided artifact detection, live ERP -feedback, explanations) because we control the whole surface. - ---- - -## 2. Why this exists — the WASM gap - -BrainWaves runs its analysis (MNE-Python) **in-browser via Pyodide/WASM inside a -web worker** (see the `pyodide-mne` skill and `docs/pyodide-in-electron-vite.md`). -That environment has hard constraints: - -- The worker uses Matplotlib's **`agg` backend** — headless, buffer-based. There - is **no GUI event loop and no window**. WebAgg (Matplotlib's browser backend) - does not work in a worker context at all. -- Every *static* plot we render today (PSD, topo map, ERP) works by having Python - `savefig()` an **SVG string**, tagging it with a `plotKey`, and shipping that - string back over the worker message channel to render in `PyodidePlotWidget`. -- `epochs.plot()` is the **only** analysis call that tried to be *interactive*. - It returns a live Matplotlib Figure object, which (a) has no GUI to display in, - and (b) can't even cross the worker boundary — a `PyProxy`/Figure isn't - `structuredClone`-able, so `postMessage` throws `DataCloneError`. - -**This is not an MNE-version problem — it's architectural.** We install the latest -MNE from PyPI (`internals/scripts/InstallMNE.mjs` lists `mne` **unpinned** in -`PYPI_PACKAGES`, so `postinstall` grabs whatever is current — a modern 1.x). The -recent errors (`plot_psd` → `compute_psd`, `events=None` → `events=False`) were -just the code catching up to the modern MNE API; no MNE version brings back native -Matplotlib GUIs in WASM. The only path to interactive epoch review is to build the -UI ourselves — which is what this plan is for. - -> **Note (grounding):** MNE is unpinned today. If exact-reproducibility of the -> cleaned output matters (design goal 3), consider pinning the MNE version in -> `InstallMNE.mjs` so a silent upstream bump can't change epoching/averaging -> behavior out from under the tests. - ---- - -## 3. What MNE's Matplotlib GUI did (the experience to replicate) - -`epochs.plot()` opened an interactive browser. Reference behavior: - -**Layout** -- Epochs laid out **side by side horizontally**; channels **stacked vertically**. -- Vertical divider lines between epochs; epoch index labels along the bottom. -- A configurable window of `n_epochs` visible at once (our call used 6). -- Epochs colored by **event/condition** (our numeric marker codes → conditions), - with a legend. -- Event markers drawn as vertical lines within each epoch. - -**Navigation** -- Scroll through epochs (←/→ / Page keys) and channels (↑/↓). -- Amplitude **scaling** up/down (`scalings='auto'` set the initial scale). -- Butterfly mode, DC-removal toggle, annotation toggle, help overlay. - -**The core action — rejection** -- **Click an epoch** → toggle it "bad" (visually greyed). On window close, the - marked epochs are **dropped** (`epochs.drop(indices)`). -- **Click a channel label** → mark the channel bad (`epochs.info['bads']`), - excluding it from downstream analysis. - -**Result** -- On close, the Epochs object is mutated: bad epochs dropped, bad channels - flagged. That cleaned object is what gets saved (`-cleaned-epo.fif`) and fed to - topo/PSD/ERP. - -**Adjacent MNE capability we should exploit** -- MNE can **auto-flag** epochs via peak-to-peak `reject` thresholds, recording - *why* each was dropped in the **`drop_log`**. This is gold for onboarding: - "we flagged these as likely blinks — here's the trace, do you agree?" - ---- - -## 4. What "cleaning" actually means (and a caveat) - -Cleaning = **removing artifact-contaminated epochs and bad channels** so the -average (ERP) reflects brain activity, not blinks/muscle/movement. Common -artifacts a student should learn to recognize: - -- **Eye blinks** — large, slow frontal deflections (AF7/AF8 on Muse). -- **Muscle/EMG** — high-frequency bursts. -- **Movement/drift** — slow baseline wander. -- **Electrode pop** — sudden step in one channel. - -**Caveat that raises the stakes:** filtering already happens at load (`filterIIR` -1–30 Hz). So *without* interactive rejection, today's "Clean Data" does no real -cleaning — it just re-saves every epoch. The interactive review **is** the -feature; there's no meaningful non-interactive fallback. (A read-only static SVG -of the epochs is possible as a stopgap, but it can't clean anything.) - ---- - -## 5. Design goals - -1. **Onboarding-first.** A newcomer should leave understanding epochs and - artifacts. Explanations, a guided mode, plain-language cues — not jargon walls. -2. **Fully featured & interactive.** Parity-plus with MNE's GUI: reject epochs, - flag channels, scroll, scale, zoom, condition coloring. -3. **A tool experts trust.** Auto-suggestions must be overridable; nothing hidden - or magic; the resulting cleaned data must be exactly what MNE would produce. -4. **Live feedback.** Ideally, show the **ERP updating as you reject** — the - single most powerful teaching moment (see the signal get cleaner). -5. **Hackable & extensible.** Fits the CLAUDE.md horizon (block-based programming, - embedded notebooks). Don't leak MNE/Pyodide abstractions into the UI. -6. **Device-agnostic.** Works for 4-ch Muse today, N-ch (Neurosity, external LSL) - tomorrow. - ---- - -## 6. Replicating it in React — the pieces - -Four concerns. Each has real design choices (deferred to the planning loop). - -### 6a. Data path: Python → renderer -We stop shipping a *GUI object* and instead ship the **raw numbers**, then render -them ourselves. Needed from Python per "clean" request: -- Epoch data array: `epochs.get_data()` → shape `(n_epochs, n_channels, n_times)`. - (Returns float64; see the transport note below on downcasting to Float32.) -- Metadata: `ch_names`, `sfreq`, `times`, **per-epoch condition codes** - (`epochs.events[:, -1]` — the numeric marker codes, *labeled* via the marker - registry's `codeToLabel`, not stored on the registry itself), and the - **auto-reject flags + `drop_log`** for suggestions. - -> **Grounding — exclude the Marker/stim channel from the arrays.** `get_data()` -> returns *all* channels, including the trailing `Marker` channel that carries the -> numeric event codes. The existing channel picker already drops it -> (`requestChannelInfo` runs `[ch for ch in clean_epochs.ch_names if ch != -> 'Marker']`); `get_epochs_arrays` must do the same, or the reviewer renders the -> raw code channel as a bogus "trace" and `ch_names` / the channel count are -> off-by-one. (The per-epoch condition codes still come from `epochs.events[:, -> -1]`, which is unaffected by dropping the channel.) - -> **Grounding correction — the registry gives labels, not colors.** -> `buildMarkerRegistry` (`markerRegistry.ts`) returns only `{ codeToLabel, -> eventId }`. There is **no color** on it. Condition colors today are hardcoded -> RGB palettes inside `utils.py` (`plot_topo`, `plot_conditions`). So condition -> coloring in the React UI needs a **new color source** — decide whether to (a) -> define a palette UI-side keyed by condition label, or (b) promote the `utils.py` -> palette into a single shared source both Python plots and the React reviewer -> read from (preferred, avoids the ERP/topo legend and the reviewer disagreeing on -> which color is which condition). Track this as a small design decision, not a -> reuse of existing code. - -**Transport is the crux** (the lesson of this whole debugging session): don't -JSON-serialize float arrays and don't return a `PyProxy`. Get the numpy buffer as -an **`ArrayBuffer`** and post it as a **transferable** (zero-copy); the metadata -above rides as JSON on the same message. Buffers cross cleanly; Figures don't. - -> **Downcasting to Float32 is safe here — and only here.** `get_data()` is -> float64; halving it to Float32 loses precision, but this buffer is *display -> only*. The apply path (§6d) is **index-based** (`epochs.drop(indices)`) — the -> epoch samples never round-trip out of Python and back, so the cleaned `.fif` -> stays bit-identical to what MNE would produce (design goal 3). Keep it that way: -> never reconstruct epochs from the Float32 buffer on the Python side. - -**This means extending the worker message contract, not just adding a Python -helper (grounded in `webworker.js` today).** The current handler is -one-size-fits-all: it runs `data`, and if the result has `.toJs` it converts the -`PyProxy` and posts `{ results, plotKey, dataKey }` **with no transfer list** — so -it can't ship a zero-copy buffer. Phase 0 must: -- Return the numpy buffer as an `ArrayBuffer` (e.g. `arr.tobytes()` off the - `PyProxy`, or via the emscripten heap) and `self.postMessage({ buffer, meta, - dataKey }, [buffer])` — the `[buffer]` transfer list is mandatory, or the buffer - is structured-cloned (a copy). -- Route it on a **new `dataKey`** (e.g. `'epochArrays'`) so it bypasses the - existing PyProxy→`toJs`→SVG-string switch in `pyodideMessageEpic` (which assumes - results are plain JS or an SVG string). - -### 6b. Rendering -Muse is tiny (4 ch × ~256 samples × dozens of epochs), but we must not design for -4 channels — Neurosity (8) and external LSL devices (32–64) are on the roadmap. -- **Canvas 2D** is the pragmatic default (smooth for thousands of points). -- **WebGL** if channel/epoch counts get large. -- **SVG/DOM overlay** on top for interaction targets (epoch columns, channel - labels, tooltips, selection highlights) — cheap hit-testing and accessibility. -- Likely a **hybrid**: canvas traces + DOM/SVG interaction layer. - -### 6c. Interaction model (parity-plus with MNE) -- Click/tap an epoch → toggle reject (clear visual state). -- Click a channel label → toggle bad channel. -- Scroll/scrub epochs and channels; amplitude scaling; horizontal zoom. -- Condition coloring + legend. -- **Beyond MNE:** hover tooltips ("this looks like a blink"), a "reject all - flagged" / "review flagged only" mode, keyboard-first flow, undo. - -### 6d. Apply path: renderer → Python -- Collect rejected epoch indices + bad channels → dispatch an action → epic posts - to the worker → Python `epochs.drop(indices)` + set `info['bads']` → save - `-cleaned-epo.fif`. -- The result must be **bit-identical to what MNE's GUI would have produced** — the - UI changes, the science does not. - -**Persistence is a real gap — the Clean→Analyze round-trip is broken today.** -Traced end to end against `webworker/`, `src/main/index.ts`, `src/preload/index.ts`: -- **Save side:** `saveEpochs` (`webworker/index.ts`) posts `raw_epochs.save("<host - OS path>")`, but Pyodide's worker FS is **MEMFS (in-memory)** — there is **no - NODEFS/`syncfs`/mount anywhere in `webworker/`**, so the write lands in the WASM - virtual FS, never on host disk. -- **Load side:** the Analyze screen re-reads *host disk* both times — at - `componentDidMount` it calls `readWorkspaceCleanedEEGData` (main-process `fs`) to - populate the picker, then on selection `LoadCleanedEpochs` → `writeEpochsToMemfs` - → `fs:readFileAsBytes` stages host bytes into MEMFS. It never reuses in-session - MEMFS epochs. -- **The gap:** nothing ever writes the cleaned `.fif` *to* host disk. Main has - write IPC (`fs:storePyodideImagePng`, `eeg:createWriteStream`, - `fs:storeAggregatedBehaviorData`) but **none writes an epoch `.fif` from the - worker**, so a fresh workspace has nothing for Analyze to load. The fix is a - **new MEMFS→host write-back bridge**, and because the worker can't reach - `ipcMain` it must cross every process boundary (see the `electron-ipc-channel` - skill) — don't collapse it to "postMessage → handler". The full chain: Python - `save()` to a MEMFS path → worker `pyodide.FS.readFile(path)` + `postMessage` the - bytes back on a **new `dataKey`** (e.g. `'savedEpochs'`, routed in - `pyodideMessageEpic` beside the existing `epochsInfo`/`channelInfo` cases — which - return no transfer list today, so shipping bytes zero-copy means extending that - reply path too) → a new epic → a new `window.electronAPI` method → the preload - bridge → a new main handler. **Reuse anchor, not new machinery:** - `fs:storePyodideImagePng` (`src/main/index.ts` line 315) is already this pattern — - `(title, imageTitle, rawData: ArrayBuffer)` → `Buffer.from(rawData)` → - `fs.writeFile` to disk; the write-back handler should mirror *it* (a binary - renderer→disk write), not `fs:readFileAsBytes`. This is not a "persist" nicety — - **it repairs a currently broken flow**. - -### 6e. The onboarding layer (the differentiator) -- Plain-language explanations of epochs and each artifact type. -- **Guided mode** (default for newcomers): step through auto-flagged epochs with - "why we flagged this," student confirms/overrides → teaches artifact spotting. -- Channel legend tied to head position (Muse 10-20: TP9/AF7/AF8/TP10). -- **Live ERP preview** pane that updates as epochs are rejected. -- Tone: encouraging, lighthearted, student-facing. - ---- - -## 7. Architecture fit & constraints - -- **Worker protocol** (`pyodide-mne` skill): today's plots use fire-and-forget - `postMessage` + `plotKey`/`dataKey` reply routing through `pyodideMessageEpic`. - Note the `dataKey` pattern **already does request/response round-trips** - (`epochsInfo` → `SetEpochInfo`, `channelInfo` → `SetChannelInfo`), so fetching - epoch arrays and applying rejection can be built on it directly — a `runPython` - RPC is **not a hard prerequisite**. The `TODOS.md` item ("(Optional) Full - Pyodide worker RPC") itself says it's only worth doing "if the FIFO sequencing - ever actually bites." Where it *would* help this feature: an `await`-able RPC - lets an apply-then-refresh sequence (drop epochs → save → re-fetch stats/ERP) - read real results instead of relying on worker FIFO ordering across several - fire-and-forget messages. Treat it as an ergonomics/scaling call, not a blocker - (see Open Question 2). -- **New Python helpers** (`webworker/utils.py`): `get_epochs_arrays(epochs)` → - buffer + metadata; `apply_rejection(epochs, drop_indices, bad_channels)`. Keep - them native-testable (the `tests/analysis/` pattern) so cleaning logic is - verified against real MNE in CI. -- **New epic(s)** in `pyodideEpics.ts` + **new actions** (fetch/set epoch data, - apply rejection). Reuse `buildMarkerRegistry` for condition **labels** (code↔label - only, no colors — see §6a for where condition colors must come from). -- **New React component** (`EpochReviewer` or similar) **added to** - `CleanComponent`. Correction: `CleanComponent` has **no plot area** to replace — - today it renders only subject/recording `<select>`s, Load/Clean buttons, and - epoch-count stats (`renderEpochLabels`).

Styling: shadcn/ui + Tailwind, - brand teal, student tone. -- **Constraints to respect:** headless `agg` in the worker; no large-array JSON; - transferables for buffers (which means extending the worker's `postMessage` to - pass a transfer list — see 6a); keep main/renderer/worker separation clean; - don't leak Pyodide/MNE types into React. - ---- - -## 8.

Ties into #1 — the settling explanation and these tips are the same "help me -get a good signal" surface. - -**Where it lives:** -- Content + stepper: `src/renderer/components/CollectComponent/HelpSidebar.tsx` - (`HELP_STEP` enum + `renderHelpContent`). Exports `HelpSidebar` (full panel) and - `HelpButton` (toggle). -- Mounted only in the Collect flow: `CollectComponent/PreTestComponent.tsx` - (lines 125–168). `HelpButton` alone also appears in `AnalyzeComponent.tsx:514`. -- **Not present** on Explore EEG (`EEGExplorationComponent.tsx`) — that's the gap. -- File already carries a TODO: *"Refactor this into a more reusable Sidebar component - that can be used in Collect, Clean, and Analyze screen"* — this item cashes that in. - -**Emotiv-specific content to fix (device-agnostic rewrite):** -- `HELP_STEP.SIGNAL_SALINE` — "Saturate the sensors in saline" is Emotiv gel/saline-cap - language. Muse uses dry/conductive electrodes — no saline soak. Drop or replace with - Muse-appropriate guidance (skin contact, sweep hair, dampen skin if very dry). -- `SIGNAL_CONTACT` — "reference electrodes right behind the ears" *is* Muse-accurate - (TP9/TP10 sit behind the ears), keep it. Audit the rest for Emotiv assumptions. -- Consider driving tips off the connected `deviceType` (Muse vs Neurosity vs external - LSL) so the copy matches the hardware, rather than one hard-coded device. - -**Proposed fix shape:** -- Extract `HelpSidebar` into a reusable, device-aware help panel (honors the existing - refactor TODO). Add device-agnostic settling copy (folds in #1's explanation). -- Mount the `HelpButton` + panel on `EEGExplorationComponent.tsx` so Explore gets the - same signal-quality help. -- Ponytail: don't build a full per-device content system if two shared strings + one - Muse-specific override covers today's devices. Generalize only as far as the current - device set needs. - -## 4. Collect "Run Experiment" landing — ugly, wastes space, redesign - -**Observed (step 2 COLLECT, pre-run landing):** the screen looks poorly designed. A -mystery empty input bar under the title, metadata stacked as plain text, a giant -full-width button, then a huge empty lower half. Wants efficient use of space. - -**Where it lives:** `src/renderer/components/CollectComponent/RunComponent.tsx` -(the `!isRunning` branch, lines 102–134). - -**Concrete problems found in the markup:** -- **The "empty input bar" is actually the edit button.** Line 106–112: - `<button className="flex justify-end w-full">✏</button>` — a full-width button holding - only a right-aligned pencil emoji. It renders as an empty full-width bar that reads as - a broken/empty text field. Should be a small icon button beside the title or the - subject metadata, not a `w-full` bar. -- **Metadata is unstyled stacked text** (Subject ID / Group Name / Session Number) — - no card, no grouping, weak hierarchy. -- **`Run Experiment` is `w-full`** (line 125) — oversized primary action. -- **Everything is top-left with a vast empty lower half** — no layout using the space - (e.g. centered card, or a two-column with device/signal status). -- **Redundant nested wrapper:** the outer `<div>` (line 97) *and* the inner `!isRunning` - `<div>` (line 103) both set `h-screen p-[3%] bg-gradient-to-b …` — double gradient + - double screen-height padding. Cheap cleanup, collapse to one. -- **Title duplicates the nav breadcrumb** — `<h1>{title}</h1>` repeats - "Faces_and_Houses" already shown in the top nav dropdown. Consider dropping or - repurposing. - -**Proposed fix shape:** -- Rebuild as a compact centered card: title (or drop it), a clean subject/group/session - summary block with a small inline edit (pencil) affordance, a right-sized primary - "Run Experiment" button. Fill the space intentionally (center the card, or add - device/signal-quality status alongside so the operator confirms readiness before run). -- Collapse the redundant `h-screen`/gradient wrapper. -- Design-shaped — worth a `/design-review` or `/design-consultation` pass in the impl - session rather than eyeballing spacing. - -**Ponytail:** this is one small component. Don't introduce a layout system — a single -centered `Card` (shadcn `Card` already exists) + right-sized button covers it. - -## 5. No forward breadcrumb after finishing a run — flow dead-ends on Collect - -**Observed:** completed the experiment and landed back on the same "Run Experiment" -screen. Nothing indicates the run is done or points forward to Clean. The only way to -advance is the top workflow nav (3 CLEAN) — undiscoverable for a first-timer; the flow -dead-ends. - -**Where it lives:** -- Run finish path: `RunComponent.tsx` `onFinish` → `ExperimentActions.Stop({data})` - (line 89–94). When `isRunning` flips false, it re-renders the *same* pre-run landing - (the `!isRunning` branch, line 102) — there is **no post-completion state**. It looks - identical to before the run, so "did it even record?" is unclear too. -- Forward nav today: the workflow steps in - `src/renderer/components/SecondaryNavComponent/index.tsx` (`onStepClick` per step) → - Clean route is `SCREENS.CLEAN.route` (`routes.tsx`, `constants.ts`). That's the only - COLLECT→CLEAN path. - -**Proposed fix shape:** -- Give `RunComponent` a distinct **post-run / completion state** (track "a run finished - this session", e.g. off the `Stop` result / recorded file) that: - - confirms the recording succeeded (filename, trial/marker count if cheap), and - - shows a primary **"Clean your data →"** CTA that navigates to `SCREENS.CLEAN.route` - (reuse the same routing the secondary nav step uses), plus a secondary "Run again." -- This is the same "guide the operator to the next step" gap that #4's redesign touches - — do them together in the Collect/Run pass. - -**Ponytail:** don't build a wizard. One completion panel with a "Clean your data →" -link-button (react-router `Link` is already imported in `RunComponent`) closes the gap. - -## 6. Clean screen — multiple issues (layout, labels, viewer, and a real units bug) - -**Screen:** `src/renderer/components/CleanComponent/index.tsx` (+ `webworker/utils.py`). -Dano's walkthrough surfaced four UX asks plus, on auto-flag, a genuine data bug. - -### 6a. Settings gear icon is mis-sized -The ⚙︎ auto-flag settings button (`CleanComponent/index.tsx` ~line 352–359) looks -too-big / not-big-enough next to "Clean Data" and "Auto-flag artifacts". Size it to -match the adjacent buttons (icon-button sizing / same height). - -### 6b. Condition labels show STIMULUS_1 / STIMULUS_2 instead of real names (Faces, Houses) -Counts, legends, and the ERP all read "STIMULUS_1 / STIMULUS_2". Should show the -experiment's real condition names ("Faces", "Houses"). -- Source of the generic labels: `src/renderer/utils/eeg/markerRegistry.ts` — - `CODE_TO_LABEL` is hard-coded `STIMULUS_1..4` (deliberately "condition-neutral"). - `buildMarkerRegistry` only ever emits those. -- Fix shape: let the registry derive a human label from the experiment's stimulus - metadata (per-experiment code→name map, e.g. Faces_and_Houses: 1→Faces, 2→Houses), - falling back to `STIMULUS_n` when unknown. Keep the numeric code contract intact - (labels are display-only; codes still drive CSV + MNE `event_id`). Thread the real - label into the Clean counts/legend/ERP. -- Ponytail: don't build an i18n/label system — a per-experiment `{code: name}` map on - the experiment object, read by `buildMarkerRegistry`, covers it. - -### 6c. Epoch viewer is too small and renders poorly -The Epochs panel gets too little real estate and the traces render badly (same -SVG-trace rendering concern as #2). Ties to the epoch-reviewer WebGL/`drawEpochs` -question already logged (`docs/epoch-review-ui-plan.md` OQ1, TODOS Phase 4). - -### 6d. Re-layout to prioritize Epochs + add a reject-onboarding flow -Give the Epochs viewer much more space, and preempt an onboarding flow that teaches -students how to read epochs and reject bad ones. **This is already scoped** as -**Epoch reviewer Phase 3 — onboarding layer** in TODOS.md (plain-language epoch/artifact -explanations, guided mode, channel legend tied to head position). This walkthrough is -direct evidence for prioritizing it. Route the product questions (onboarding depth, -guided-mode-as-default — TODOS OQ3) through /office-hours or /plan-ceo-review. - -### 6e. 🔴 BUG: Auto-flag rejects ALL epochs — µV→V units error (NOT threshold too low) -**Observed:** "Auto-flag artifacts" flagged all 16/16 epochs → ERP averages over 0 -epochs (blank). Flag reasons: **peak-to-peak 65,715,724 µV / 66,228,063 µV / -89,980,195 µV**. Dano's read was "thresholds too low"; the real cause is deeper. - -**Root cause (grounded):** 65 million µV = ~65 **volts** peak-to-peak is physically -impossible for EEG (real Muse ptp is tens of µV; the amp rails well under 1 mV). The -value is inflated ~1e6×: -- `webworker/utils.py` `load_data` (lines ~90–95) builds `RawArray(data=data, …)` - straight from the CSV values with **no µV→V scaling**. MNE treats EEG channel data as - **volts**, but the Muse CSV is in **µV**. So a real ~65 µV excursion is loaded as - ~65 "volts". -- `suggest_rejections` (utils.py ~line 350–359) computes ptp in MNE's unit (thinks - volts) then `* 1e6` to report µV → 65 → 65,000,000 µV. Threshold default - `DEFAULT_PTP_THRESHOLD_UV = 100` (`constants.ts:12`) → `thresh_v = 1e-4 V`, but ptp is - ~65 in MNE units, so **every** epoch exceeds it. - -**Fix shape:** scale CSV µV → V on load in `load_data` — multiply the **eeg** channels -by `1e-6` before/at `RawArray` (do NOT scale the last `stim`/Marker channel; markers are -numeric codes — see `.llms/learnings.md`). After the fix, ptp ≈ 65 µV, the 100 µV -default behaves sanely, and auto-flag stops nuking everything. **Verify against the -golden test** (`tests/analysis/test_erp_roundtrip.py`) — a global scale factor won't fail -its relative-amplitude assertions, so add an absolute-µV sanity check so this can't -regress silently. Also audit downstream consumers that assume the current (wrong) scale: -epoch viewer amplitude, `amp +/−`, ERP y-axis, `SetEpochInfo` payloads. - -**Do not** just raise `DEFAULT_PTP_THRESHOLD_UV` — that hides a real correctness bug and -would let genuine artifacts through once the units are fixed. - -### 6f. ⚠ Flagged console error (see-something-say-something) -The Clean screen logs `The specified value "NaN" cannot be parsed, or is out of range` -(repeating). Likely a DOM/SVG/input attribute being set to `NaN` — plausibly the epoch -viewer or the `amp`/threshold `<input>` receiving `NaN`. Not user-reported; flagging so -the impl session tracks it down (may share a cause with 6c/6e). - -### 6g. Auto-flag threshold: slider with device presets, not a raw µV number input -**Observed:** the threshold is a bare absolute-µV number `<input>` — students have no -idea what number to type. Make it a streamlined **slider** with sensible values -**pre-selected per device** (Muse vs Neurosity vs external LSL), so users adjust -sensitivity intuitively instead of guessing microvolts. - -**Where it lives:** `CleanComponent/index.tsx` — `autoFlagThreshold` state (default -`DEFAULT_PTP_THRESHOLD_UV = 100`, `constants.ts:12`) rendered as a numeric `<input>` in -the auto-flag settings panel (~lines 369–378); parsed in the `!Number.isNaN` handler -(~line 206–213). shadcn has no Slider yet — add `@radix-ui/react-slider` (same family as -the already-installed Select) or a styled native `<input type="range">`. - -**Fix shape:** -- Replace the number input with a slider (labeled low/high sensitivity, showing the - current µV under the hood but not requiring users to reason in µV). -- Seed the default + range from the connected device — a per-device preset map - (reasonable ptp ceilings differ by hardware). Fall back to `DEFAULT_PTP_THRESHOLD_UV`. -- **Depends on 6e:** presets are only meaningful once the µV→V units bug is fixed — - otherwise "100 µV" doesn't correspond to reality. Sequence 6e before tuning presets. - -**Ponytail:** a native `<input type="range">` + a small `{device: {min,max,default}}` -map covers this — no slider component library required unless the design calls for it. - -## 7. EEG disabled by default + no warning when running without EEG - -**Observed:** ran an experiment with EEG not connected, was **not notified**, and found -"Enable EEG" was **off by default** — nonsensical for an EEG app. Result: a run that -records behavior but no brain data, silently. - -**Where it lives:** -- Default: `src/renderer/reducers/experimentReducer.ts:38` — initial state - `isEEGEnabled: false`. Toggled via `SetEEGEnabled` (`experimentActions.ts:38`); the - toggle UI is the "Enable EEG" switch in `SecondaryNavComponent` SettingsDropdown - (wired from the workflow screens, e.g. `DesignComponent`). -- Cascade when `isEEGEnabled === false`: - - `CollectComponent.componentDidMount` skips auto-connect (only connects if EEG on). - - `RunComponent`: `isRunComponentOpen` initializes to `!isEEGEnabled` → opens straight - to the Run screen, bypassing connect/pre-test. - - `RunComponent.eventCallback` gates on `isEEGEnabled` → **no markers injected**, so - even if a device were streaming, this path wouldn't tag events. - - Net: no device, no markers, no warning — the operator only finds out later (empty - EEG, e.g. the Clean screen). - -**Proposed fix shape:** -- **Flip the default to `isEEGEnabled: true`** (one line in `experimentReducer.ts`). - EEG-on is the app's whole point; opt *out* for the behavior-only case, not opt in. -- **Warn before a no-EEG run.** When starting a run with EEG enabled but no device - connected — or with EEG disabled — surface a clear confirm ("EEG is not connected — - this run will record responses but no brain data. Continue?"). `RunComponent`'s - `handleStartExperiment` already does a `showMessageBox` confirm for file-overwrite; - reuse that pattern for the no-EEG case. -- Consider persisting the user's EEG-enabled choice rather than resetting per session. - -**Ponytail:** the default flip is one line; the guard is one extra `showMessageBox` -branch in the existing `handleStartExperiment`. No new state machine needed. - -## 8. Remove the "Insert the USB Receiver" modal step (Emotiv-era, irrelevant for Muse) - -**Observed:** the connect flow still has an "Insert the USB Receiver" step. Muse is -Bluetooth — no dongle. Remove it. - -**Where it lives:** `src/renderer/components/CollectComponent/ConnectModal.tsx`. -Local `enum INSTRUCTION_PROGRESS { SEARCHING, TURN_ON, COMPUTER_CONNECTABILITY }` -(line 42). Flow: `TURN_ON` ("headset on & charged") → **`COMPUTER_CONNECTABILITY`** -("Insert the USB Receiver", lines ~260–293) → `handleSearch()` → device list. - -**Exact removal (trivial, ready to implement):** -1. Delete the `COMPUTER_CONNECTABILITY` render block (lines ~260–293). -2. In the `TURN_ON` step, change **Next** (lines ~245–255) from - `handleinstructionProgress(INSTRUCTION_PROGRESS.COMPUTER_CONNECTABILITY)` to call - `this.handleSearch` directly (what the USB step's Next did) — so "headset on" flows - straight to searching. -3. Remove `COMPUTER_CONNECTABILITY` from the enum. -4. Leave the device-list "Back" / "Don't see your device?" targets (`…Progress(1)` = - `TURN_ON`) as-is — still valid. - -**Note:** this is small and low-risk — a good candidate to just land in the impl session -(clean tree → one atomic commit). No product decision needed. - -## 9. Analyze screen empty after Clean→Analyze + "Go to Folder" broken (two real bugs) - -### 9a. 🔴 BUG: "Go to Folder" on Home does nothing — relative path to shell API -**Observed:** the "Go to Folder" button on the Home screen doesn't open the workspace, -blocking any manual check of what was written. - -**Root cause (grounded):** `src/renderer/utils/filesystem/storage.ts:29` -``` -openWorkspaceDir = (title) => api().showItemInFolder(path.join('BrainWaves_Workspaces', title)) -``` -passes a **relative** path `"BrainWaves_Workspaces/<title>"` to -`shell.showItemInFolder` (`src/main/index.ts:159`). `shell.showItemInFolder` requires an -**absolute** path — given a relative, non-existent one it silently no-ops. The real -workspace dir is absolute: `path.join(os.homedir(), 'BrainWaves_Workspaces', title)` -(`main/index.ts:116–118`, `getWorkspaceDir`). Called from -`HomeComponent/index.tsx:250`. - -**Fix shape:** resolve the absolute path in main, not the renderer. Add a -`shell:openWorkspaceDir` handler that does `shell.openPath(getWorkspaceDir(title))` -(opening the folder is better UX than `showItemInFolder`, which highlights the item in -the parent). Point `openWorkspaceDir` at it. Removes the relative-path guesswork and the -duplicated `'BrainWaves_Workspaces'` literal. Small, isolated fix. - -### 9b. 🔴 BUG: Analyze "Select Clean Datasets" is empty after cleaning -**Observed:** cleaned the dataset, clicked Analyze, and the "Select Clean Datasets" -picker is empty — nothing to analyze. - -**Grounding — the write/read paths MATCH, so the file wasn't written (not a scan miss):** -- Write: `fs:writeCleanedEpochs` (`main/index.ts:332`) → - `<workspace>/Data/<subject>/EEG/<subject>-cleaned-epo.fif`. -- Read: `fs:readWorkspaceCleanedEEGData` (`main/index.ts:246`) scans the workspace - recursively for the `epo.fif` suffix — `-cleaned-epo.fif` matches. So the picker would - list the file **if it existed**. Empty ⇒ no cleaned `.fif` on disk. -- Save trigger: the worker must emit a `dataKey === 'savedEpochs'` message with a buffer; - only then does `pyodideEpics.ts:129–145` call `writeCleanedEpochs` (+ "Cleaned data - saved" toast). If that message/buffer never arrives, nothing is written and nothing - errors. - -**Two suspects for the impl session (verify, don't assume):** -1. **Consequence of the units bug (6e):** on this run auto-flag had marked **all 16/16 - epochs** for rejection. If Dano clicked "Clean Data" with everything flagged, the drop - removes every epoch → the saved Epochs object is **empty**, which may fail to write a - valid `.fif` (or write a degenerate one that the scan/parse skips) — with no user- - facing error. Fix 6e first, then re-test a normal clean (few rejections). Also: **guard - against cleaning to zero epochs** (warn / block "Clean Data" when the drop set == all - epochs) so a student can't silently destroy their dataset. -2. **The known worker-RPC FIFO fragility** (see `.llms/learnings.md` / TODOS "Full Pyodide - worker RPC"): `worker.postMessage` awaits are no-ops, so the drop→save→re-fetch - sequence relies on FIFO ordering. If the save step's buffer is dropped/empty, the - `savedEpochs` branch silently writes nothing. Add an explicit failure surface — if - `savedEpochs` never arrives (or arrives empty), toast an error instead of failing - silent. - -**Common thread with the whole walkthrough:** silent failure. Collect ran with no EEG and -no warning (#7); auto-flag nuked everything from a units bug (#6e); cleaning to zero -epochs produced an unanalyzable dataset with no error here. The impl session should add -user-facing guards/toasts at each of these "you just destroyed your data" moments. - -<!-- append new walkthrough items below as Dano surfaces them --> - ---- - -## Test coverage (from /plan-eng-review) - -Frameworks: **pytest** (`tests/analysis/`, native MNE — the data path) + **vitest** (JS). -Most UX items are visual → verified via `/qa` or manual, no unit test.
