The Playwright suite had no linter and no formatter — only tsc. Add flat-config ESLint
(typescript-eslint, type-aware) and Prettier (2-space, matching the suite's style).
Rules keep the ones that catch real TEST bugs and drop the noise:
- no-floating-promises KEPT — an un-awaited request/assertion can let a test end before it runs,
passing vacuously. It caught one: the SSE reader loop in sse-listener is now explicitly `void`.
- no-unused-vars KEPT — caught three dead bindings (an unused adminToken fixture arg, an unused
`api` arg, an unused JPEG_MAGIC import), all removed.
- no-explicit-any OFF — all test code; `any` is the honest type for an untyped res.json() body or
a page.evaluate() return.
- no-empty-pattern OFF — Playwright's dependency-free fixtures are `async ({}, use) => {}`.
Refactor: `const BASE = process.env.E2E_FRONTEND_URL ?? '...'` was redeclared verbatim in 23
files — extracted to helpers/env.ts and imported, so a port/scheme change is one edit not a sweep.
Then `prettier --write`. Verified: eslint clean, tsc clean, prettier clean, desktop suite 210
passed / 1 skipped. (One mobile spec flaked once under retries:0 — a pre-existing cross-test
reflow-timing vector from the flakiness audit, not this change: the each-key edit is stable across
16 isolated runs and a clean full mobile re-run.)

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).

The "429 from server is surfaced (no infinite retry storm)" test routed
`**/api/v1/feed`, but the app requests `/api/v1/feed?limit=20` — a plain glob
without a trailing wildcard doesn't match a URL with a query string, so the
route never fired: `attempts` stayed 0 and `expect(attempts).toBeLessThan(15)`
passed trivially. The test never forced a 429 or exercised any retry behavior.
Fix: match with a regex `/\/api\/v1\/feed(\?|$)/` (catches the query-string URL,
excludes /feed/delta), and gate on `attempts >= 1` before judging retry
behavior so it can't pass again without actually hitting the throttled endpoint.
Found during self-review of the test-quality batches.

- ContextSheet: add data-testid="context-sheet". longpress tests targeted the
open sheet via the `.translate-y-0` animation class (breaks on any animation
refactor) — now target `[data-testid="context-sheet"][aria-modal="true"]`,
which is stable and unambiguous vs. the centered LightboxModal (also aria-modal).
- toast-on-failure: the like button was `button.filter(hasText:/\d+/).first()`,
which could match any digit-bearing button (e.g. the comment count) → use the
stable aria-label "Gefällt mir".
- config stats: assert the exact user_count (4 = 3 seeded guests + admin) instead
of `>= 3` — deterministic after the per-test truncate, catches under/overcount.
- offline-network 429 test: replace the fixed 3s waitForTimeout with a
poll-until-the-retry-count-stabilizes (faster, and a real storm never stabilizes
→ the poll fails, which is the intended outcome).
Note: reviewed the "config restore not in try/finally" finding — it's a non-issue.
The truncate auto-fixture wipes+reseeds the whole config table (and clears the
rate limiter) before every test, so config state cannot leak between tests.
All affected specs verified green.

Several tests ran green while asserting nothing. Replace them with real
assertions, and fix the SSE helper they depend on.
sse-listener: exchange the JWT for a single-use ticket (POST /stream/ticket) and
connect via ?ticket= — the helper still used the dead ?token= scheme, so every
SSE-based assertion would have silently failed to receive events.
like-comment:
- "like is idempotent" asserted nothing (void feed; void b) → now seeds a real
upload and pins the like contract: counted once per user, toggles off on repeat
(guards double-count), and a second user's like is counted independently.
- "comment → SSE to B" asserted length >= 0 (always true) → B now subscribes to
the stream, A comments, and B must receive the new-comment event for that upload
(comment_count === 1). ~30s due to reverse-proxy SSE buffering; timeout raised.
sse-realtime: only checked a nav link was visible → now counts EventSource opens
and asserts a fresh stream connection after hidden→visible (also fixes the sim,
which set visibilityState but not document.hidden, so the close never fired).
multi-tab "SSE delivers to both": only checked nav links → now asserts each tab
opens its own stream connection (delivery isn't asserted — it hinges on the ~30s
proxy buffering; connection establishment is the reliable, honest signal).
safe-area: delete the /join probe whose only assertion was Array.isArray(x) ===
true (always true); the real sheet-level env() check already exists below it.
All verified green against the live backend.
