Reported 2026-05-20: the receiving state machine had four states (draft → counted → staged → closed) where the middle pair was pure ceremony. Real-usage data on entech: state distribution: 14 draft, 4 closed (zero `staged` records) median dwell counted → staged: 11 seconds median dwell staged → closed: 4 minutes `staged` captured no fields, fired no gates, mapped to the same SO `x_fc_receiving_status='partial'` as `counted`. Pure click-through. Cleanup: - State Selection retains `staged` as `Staged (legacy)` so historical records remain readable; new transitions never write it. - statusbar_visible drops it from the chevron header. - action_mark_staged becomes a thin shim that advances counted → closed directly (any old button binding still works). - action_close now accepts `counted` as a valid source state (was previously only `staged` / legacy `accepted` / `resolved`). - View: "Stage for Racking" button removed. "Close" button renamed to "Close — Racking Confirmed" so the racking-crew confirmation meaning stays obvious. - _update_so_receiving_status mapping unchanged for legacy `staged` (still maps to partial) — only the comment block updated to describe the new canonical flow. Migration 19.0.3.20.0 advances any `staged` records to `closed` and syncs the linked SO's x_fc_receiving_status to `received` so downstream gates (job step start, mark_done qty check, cert creation) don't see a stale "partial" status. Module: fusion_plating_receiving 19.0.3.19.0 → 19.0.3.20.0. Tests: TestQtyReceivedPropagation updated — 5 tests dropped the action_mark_staged() call, walk draft → counted → closed directly. All 11 tests green (carrier 6 + propagation 5). Verified on entech: existing 14 draft + 4 closed records untouched. Direct draft → counted → closed transition works end-to-end on RCV-30041 (was the test target). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
