Fixes anonymous essay submissions (the GoTrue anonymous claim carries an empty-string email, which shadowed the client-supplied email and 400'd every online hand-in), wraps the student essay/test pages in ToastProvider so nudge toasts actually render, and broadcasts `submitted` right before telemetry tears down so the live monitor flips to Submitted in real time. The essay roster badge and essay-list submitted count now also hydrate online submissions (essay_submissions) instead of only offline imports, and the submit-essay/submit-test edge functions get extracted, unit-tested validation helpers (anonymous-email resolution, answer sanitization, expiry + attempt policy). 🤖 Generated with Codebuff Co-Authored-By: Codebuff <noreply@codebuff.com>

📝 WalkthroughWalkthroughThe changes add online essay submission tracking, realtime submitted events, shared essay email resolution, and shared test validation helpers. Tests cover grouping, email behavior, answer sanitization, deadlines, and attempt policies. ChangesSubmission integrity and tracking
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change improves online submissions, toast visibility, live status updates, and roster counts, but the current implementation can miss live submission transitions and mishandle two boundary inputs, including returning a 500 for a null request body. Merge should wait for these bounded correctness fixes. Sequence Diagram(s)sequenceDiagram

🌐 Web query:
For @supabase/supabase-js 2.112.2, verify the RealtimeChannel.send acknowledgement result when channel config does not set broadcast.ack=true, and verify the result type returned when ack is enabled.
💡 Result:
For @supabase/supabase-js version 2.112.2, the behavior of RealtimeChannel.send for broadcast messages depends on the channel's broadcast configuration [1][2]. When broadcast.ack is not set to true (i.e., it is false or undefined), the promise returned by channel.send resolves immediately with the value 'ok' [1][2]. It does not wait for an acknowledgment from the Realtime server [3][4]. When broadcast.ack is set to true in the channel configuration, the promise returned by channel.send resolves only after the Realtime server sends an acknowledgment that it has received the broadcast message request [4][5]. The returned value is a string, which will be 'ok' upon successful acknowledgment, or 'error'/'timed out' if the acknowledgment fails or times out [1][2].

Await an acknowledged submitted broadcast before tearing down telemetry.
@supabase/realtime-js@2.112.2 defaults broadcast.ack to false, so send() resolves 'ok' without confirming server receipt. Return and await the Promise, enable broadcast.ack: true, and handle 'error' or 'timed out' before setSubmitted(true) in both submission pages. Otherwise, LiveMonitorPage can miss the live transition.

What & why
The feature side of the essay/test + live-monitoring hardening work — the e2e suite that exercises it lands in a separate testing PR (merge this first).
Anonymous essay submissions were broken. A GoTrue anonymous session carries an empty-string
emailclaim (notnull), soauthEmail ?? bodyEmaillet the empty string shadow the client-supplied email — every online hand-in 400'd with "Missing required field: studentEmail". Email resolution is now truthiness-guarded and extracted into a pure, unit-tested helper (supabase/functions/submit-essay/email.ts).Nudge toasts never rendered. The student essay/test pages mounted outside
ToastProvider, soshowToastwas a silent no-op. Both routes are now wrapped (main.tsx).Submitted status is real-time.
useLiveSessionTelemetrygained abroadcast()escape hatch; both student pages broadcastsubmittedright before telemetry tears down, andLiveMonitorPagehandles it (still falling back to persisted rows on mount).Roster/list counts ignored online hand-ins.
EssayBuilderPage's badge andEssayListPage's submitted count only read hydratedessaySubmissions(the offline import path) — onlineessay_submissionsnever counted. NewuseOnlineEssaySubmissionshook hydrates them as a status-only supplement (never persisted back).Edge-function validation extracted and pinned.
