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.
