Per-creative hook/hold/ROAS grid plus the server-computed creative intelligence: opportunity matrix, hidden winners, hook/hold quadrants, CACHED: this route wraps its live fetch in a short read-through response cache — 60s when the range includes today, 300s when the range is fully in the past.

• Entries always expire and re-fetch live; a fetch failure never falls back to a cached value.
• Polling faster than once a minute returns the identical body.
• Money fields are integer piasters (EGP x 100).
