Follow-ups from the code review of the test-quality batches: - Consolidate duplicated helpers into e2e/helpers/: seed.ts (seedUpload, seedComment, listComments, findFeedRow) and sse.ts (mintSseTicket, openStream, trackStreamOpens). Refactor authorization-deep, xss-injection, like-comment, sse-ticket-abuse, ddos, sse-realtime, multi-tab, and SseListener to use them — the upload/comment/ticket-flow contracts now live in one place each instead of being re-inlined across 3–7 specs. - xss-injection display-name loop: it navigated to /feed (which renders uploader names, not the viewer's) so "nothing fired" passed vacuously — the payload was never rendered. Now navigate to /account (the actual sink) and add a render guard asserting the payload reached the DOM as escaped text before checking __xssFired. - sse-realtime reconnect: snapshot the stream-open count AFTER backgrounding, so the "new connection" assertion is attributable to the foreground event and can't be satisfied by a spurious native/error reconnect before the toggle. - recover-page: correct the comment (auto-submit is the onPinInput handler, not an $effect). 44 affected specs verified green.

* SSE reconnection after tab background. USER_JOURNEYS.md §17 / edge cases.
|
|
*
|
|
* The app closes the EventSource on `document.hidden` and reopens it (minting a
|
|
* fresh ticket + new EventSource) when the tab becomes visible again — see
|
|
* frontend/src/lib/sse.ts. We assert the reconnect by counting stream-open
|
|
* requests rather than event delivery, which keeps the test fast and independent
|
|
* of the reverse proxy's SSE buffering.
