Harvest

The routed entry point for the end-of-unit harvest — the sweep of what the unit produced, learned, and left open into their durable sinks. The procedure, the three legs, and the sink table are owned by lib:reference/harvest.md; consult it and follow it. Do not re-derive the routing here — point there.

During execution, working notes belong in the active runtime phase sheet (state/.../phases/phase-NN.md) — disposable working context. The harvest is the wrap-up sweep that moves what matters into durable homes; the slice's notes.md (doctrine slice notes <ID> scaffolds it on demand) carries the durable prose. Honour the storage rule: live progress lives in the state tree, never in authored files.
