The award endpoint\n(POST /api/devtoberfest/cat-game/award) writes exactly one row per\n(user, event, day): 5 points per day, once per day, capped at 100 points\ntotal per event, and only while that event is active.\n\nThe natural (user, event, awardDate) tuple is the PRIMARY KEY — no surrogate\nID — so HANA enforces the once-per-day rule at the DB layer: a second insert\nfor the same day collides on the PK and the handler maps it to\n\"already-today\" (race-safe, unlike a CAP-only @assert.unique which this\nrepo's raw db.run() inserts bypass — see srv/lib/resolve-db-user.js).\n\n`createdAt` (from `managed`) is the actual award instant and is what the\ncross-container GAMEBOARD_BONUS_V1 view exposes as AWARD_DATE, so the\ngameboard's event-window filter always sees an in-window timestamp (the\nendpoint only ever inserts while the event is live).",
