-### Wiring the REAL data (currently SAMPLE)
+### Live data wiring
 
-`api/routes.py` returns sample data today. To make it live (see the big `TODO` there
-and `.claude/memory/temper-line-overview.md` in the gateway):
-
-- Import the kernel proxy: `from .._db import run_select_query` (read-only).
-- Reuse the temper status-derivation in `modules/fastpress/press/temper.py`
-  (`_temper_aggregates_all` derives on-way / in-oven / finished from planned
-  timestamps vs `NOW()`), un-scoped across **all** presses. Read
-  `production.temper_tracking` (carts grouped by `ttCartId`, keyed by origin press
-  `ttPress`) + `production.active_orders`/`finished_orders`.
-- `notVerladen` = produced good parts (cycles) − parts logged to temper. **Open
-  question:** per-press or plant-wide?
-- Scope `finished` by `range` on `ttOutOfOvenAt`. Never echo customer/price fields.
-
-Alternatively, add a public `GET /press/temper/overview` in fastpress and have the
-frontend call that — decide before wiring; keep the payload shape above either way.
+`api/routes.py` reads live MariaDB (`sample:true` only appears in the standalone
+dev fallback with no backend). Details + the exact column sources are in the gateway
+memory `.claude/memory/temper-line-overview.md`. In short: it uses the kernel proxy
+`from .._db import run_select_query` (read-only), un-scoped across **all** presses for
+plant `PLANT_NAME` — press list from `press_settings.presses`; good/chips from
+`active_orders`+`rejects`; run/stop/idle from `cycles_new` recency; carts +
+`notVerladen` from `production.temper_tracking` with position derived in SQL from the
+planned timestamps vs `NOW()` (reprints excluded). `finished` is scoped by `range` on
+`ttOutOfOvenAt`. Oven temperature is omitted (no sensor). Never echo customer/price
+fields.
