The previous in-memory _progress dict + polling SSE handler had a 30s silent
tail after completion. HTTP/2 framing in the proxy chain (Traefik) buffered
the small chunks until the stream closed, so when a transient blip caused
EventSource to reconnect, the server returned 404 and the UI stuck on the
"מתחיל…" placeholder forever. Reproduced live: 445 bytes withheld 31s.
Changes:
• web/progress_store.py — ProgressStore wraps Redis with TTL (5m), atomic
GETDEL, dict-like API. Best-effort: Redis errors are logged and swallowed
so observability outages don't break uploads.
• web/app.py — _progress is now Redis-backed; every set/get/active/pop is
awaited. SSE handler emits a heartbeat each tick (forces HTTP/2 flush),
drops the 30s post-completion sleep, and returns a terminal
{"status":"unknown"} payload instead of 404 when the task is gone — so
EventSource closes cleanly instead of reconnect-looping. New _SSE_HEADERS
set X-Accel-Buffering: no.
• web-ui useProgress(taskId, caseNumber) — 10s fallback that invalidates
the case detail if no SSE message arrived; treats "unknown" as terminal
and triggers a refetch from the source of truth.
• upload-sheet wires caseNumber through and renders "unknown" as completed.
