+# Workflow catalog (moved)
+
+Each workflow's input/output/trigger contract now lives in its own route file — one
+small read per candidate instead of a whole catalog:
+
+`references/routes/<workflow>.md` — e.g. `routes/product-launch-video.md`,
+`routes/general-video.md`, `routes/remotion-to-hyperframes.md`.
+
+The same file carries that route's interview entry (must-haves, conditionals, deferred
+asks, run-shape), so confirming a route is exactly one read.
