The "אימות פסיקה" tab reloaded its data on every tab revisit and the first
load took 1.5–3s. Two independent causes, two fixes:
Frontend (web-ui/src/lib/api/citation-verification.ts):
- staleTime 10s → 5min and refetchOnMount: false. Radix Tabs unmounts inactive
TabsContent, so switching back used to trigger a full rebuild once the 10s
window elapsed. Verify mutations still invalidate the query, so edits pull
fresh data.
Backend (mcp-server/.../case_citation_verification.py):
- The per-argument loop ran a Voyage embed + vector search + batched authority
query sequentially (N args × ~300ms waterfall). Extracted to _fetch() and
fanned out with asyncio.gather — order preserved, n_verified counter and
per-argument seen-sets unchanged. First load ~5× faster on multi-argument cases.
Pure read/assembly — no new parallel path (G2), no silent error swallowing
(search/radar still log warnings). Invariants: INV-DIG1/INV-AH unaffected
(still read-only, never cites).
