Same GoTrueClient lock contention fix as CCFilesPanel:
- transcriptionStore: add _accessToken/_userId state + setAuthInfo() action;
replace all 6 getSession() calls (startSession, flushCanvasEvents, loadSessions,
loadKeywordWatches, addKeywordWatch, deleteKeywordWatch, checkSegmentForKeywords)
with stored values — zero getSession() calls remain in the store
- CCTranscriptionPanel: destructure accessToken from useAuth; sync both values into
store via setAuthInfo() on every auth change; gate loadSessions on authUser.id
- CCCabinetsPanel: same pattern as CCFilesPanel — useAuth for token, useCallback on
apiFetch/loadCabinets, gate effect on authUser.id

Root cause: apiFetch called supabase.auth.getSession() on every API request, acquiring
the GoTrueClient internal lock. On refresh, concurrent mount of panels caused lock
contention — the loadCabinets/loadSessions fetch awaits hung, loading spinner never
cleared.
- AuthContext: add accessToken state, set/clear it alongside user on all auth events
- CCFilesPanel: apiFetch reads accessToken from AuthContext (no lock), loadCabinets
effect gated on authUser.id (fires only after SIGNED_IN, session guaranteed valid)
- CCTranscriptionPanel: loadSessions effect gated on authUser.id for same reason

- transcriptionStore: replace all supabase.auth.getUser() with getSession() so session
restoration on page refresh does not race against GoTrue network validation
- CCFilesPanel: remove selectedCabinet from loadCabinets useCallback deps; use
initialSelectionDone ref to prevent double-call on first mount
- CCTranscriptionPanel: replace hardcoded LAN IP with VITE_API_URL env var

Python heredoc string replacement missed the JSX wrapper lines due to
indentation mismatch. Rewrote App.tsx directly. Previous commit removed
the imports but left NeoUserProvider/NeoInstituteProvider in the JSX,
causing ReferenceError at runtime (Vite builds without tsc so it
compiled clean despite the undefined references).

- Remove NeoUserProvider + NeoInstituteProvider from App.tsx startup chain
- Strip user_db_name/school_db_name from CCUser; add school_id (Phase B wires it to Supabase)
- Remove DatabaseNameService from AuthContext and UserContext
- Remove provisionUser() call from login path; API endpoint preserved for Phase B decision
- Simplify UserContext.resolveProfile: fast-path JWT metadata then background Supabase fetch
- Replace user.user_db_name reads in singlePlayerPage + snapshotService with null-safe guards
- Add useDeviceContext hook (desktop/tablet/phone/iwb, persists to localStorage)
App now loads to dashboard without any Neo4j dependency at startup.
Canvas opens to blank TLDraw state; Phase B rebuilds navigation on Supabase.

Root causes of disconnection and slow transcription:
- AudioWorklet was firing every 128 native samples (~48 kHz), sending
~375 tiny WebSocket messages/sec. Server flooded with tiny frames
during silence → keepalive ping timed out → connection dropped.
- JS resampling 48 kHz → 16 kHz added CPU overhead on every chunk.
- Audio started on ws.onopen before server sent SERVER_READY, so early
frames were dropped.
Fixes:
- audioWorklet.js: accumulate 4096 samples before posting (256 ms/chunk
at 16 kHz, ~4 messages/sec), transfer ArrayBuffer zero-copy.
- transcriptionService: AudioContext({ sampleRate: 16000 }) — browser
handles native resampling, no JS resampling needed. Remove
resampleTo16kHZ entirely.
- Wait for SERVER_READY message before calling setupAudioProcessing().
- Send 'END_OF_AUDIO' string on stop so server can finalise last segment.

- transcriptionService: track finalizedSegmentCount so only newly-final
segments are emitted per WS message (was re-processing full array each
time, causing the live segment to freeze in the completed list)
- transcriptionStore: saveSegment isFinal branch now appends the passed
text directly instead of currentSegment (currentSegment was stale
relative to the incoming final)
- CCTranscriptionPanel: record button colour changed from var(--color-text)
to explicit #2563eb so it is visible in dark mode; completed segment
backgrounds changed from hardcoded #fff to var(--color-muted) so text
is readable in both themes; keyword Add button gets same blue fix

The old startTranscription() called enumerateDevices() first to find a
device ID, then getUserMedia. Without microphone permission, enumerateDevices()
returns devices with deviceId="" (empty string, falsy). This caused the
!this.selectedDeviceId check to bail out early, never calling getUserMedia,
never prompting the user for mic permission, and never creating the WebSocket.
Result: user clicks Start Recording → isRecording=true → button changes to
Stop Recording → but no mic prompt, no WebSocket, no transcription.
Fix: call getUserMedia directly (with optional echoCancellation/noiseSuppression
if no device pre-selected). getUserMedia triggers the browser permission prompt
automatically. Device selection is still honoured via exact deviceId constraint
when one has been explicitly chosen.

Before: UserContext waited for a Supabase profiles table query (~200ms)
before setting isInitialized=true, causing FullContextRoutes to show
a spinner on every page refresh even with a valid stored session.
After: UserContext immediately builds a profile from auth metadata +
localStorage (synchronous, zero network calls) and sets isInitialized=true
before the Supabase query. The Supabase profiles table is still queried
in the background and the profile is updated when it returns with
authoritative user_db_name/school_db_name data.
On refresh with a stored session: auth metadata is available
synchronously via INITIAL_SESSION, so the page renders with no visible
spinner.

BasePanel reads PANEL_DIMENSIONS[currentPanelType] to get the panel
dimensions (topOffset, bottomOffset, width). The transcription panel
type was added to the panel list and render switch during CIS Phase 3C
but was never added to PANEL_DIMENSIONS. This caused a crash whenever
the BasePanel rendered with the transcription tab active:
PANEL_DIMENSIONS["transcription"] === undefined
undefined.topOffset → TypeError: Cannot read properties of undefined
This crash appeared as a topOffset error anywhere a Tldraw canvas was
rendered (singlePlayerPage, multiplayerUser, etc.).

Three changes to singlePlayerPage:
1. Store creation no longer waits for isEditorReady. The editor ref
is already passed as optional to NavigationSnapshotService and
loadNodeSnapshotFromDatabase, so we can create and populate the
store without needing the editor to be mounted first.
2. <Tldraw> only renders when store is defined: {store && <Tldraw>}.
Previously it rendered immediately with store={undefined}, which
caused TLDraw to initialize with no backing store and crash
reading topOffset on an unresolved internal object.
3. Loading guard also checks !user so the component never renders
with a null profile before the redirect effect fires.

The previous implementation had two concurrent session recovery paths:
1. loadInitialSession() calling supabase.auth.getSession()
2. onAuthStateChange handling INITIAL_SESSION/SIGNED_IN
These raced unpredictably causing setLoading(false) to never fire in
certain interleavings, leaving the app permanently stuck on the spinner.
Fix: Remove loadInitialSession() entirely. Start loading=true. Rely
solely on onAuthStateChange — INITIAL_SESSION fires immediately with
the current session state, eliminating the race. One path, one
setLoading(false) call, no interleaving possible.

Removed NeoUserContext and NeoInstituteContext from the gateway
spinner. They were blocking ALL authenticated routes until Neo4j
graph data was loaded, which took 1-8 seconds and caused persistent
spinners. Now only UserContext (Supabase profile, ~200ms) must be
ready before routes render. Each page handles its own graph data
loading state independently.

singlePlayerPage was using useUser().user which is always null (no setter
in UserContext). This caused the redirect effect to always fire, making
the workspace completely inaccessible. Fixed by destructuring profile as
user, which IS properly set from the Supabase profiles query.
Also added 8s timeout to NeoUserContext.switchContext call to match the
NeoInstituteContext timeout fix, preventing infinite spinner if the
navigation API call hangs.

Races the SchoolNeoDBService.getSchoolNode() call against an 8-second
timeout. If Neo4j is slow or unavailable the workspace now loads within
seconds rather than waiting for the full axios 120s timeout. The context
degrades gracefully — workspace opens without institute data, error is
logged as a warning not an exception.

Reads VITE_TLSYNC_SECRET from env and appends ?token=... to the
/connect/:roomId WebSocket URI so tlsync server can authenticate connections.
