Route /admin/stocktake?session={id} · StocktakeCountSection.tsx.
Reference: mgr2 (scan + find + recent with Undo), mgr1 header.
Layout: DetailLayout.
- back “← All counts”, identity chip “#{id}”, title notes or “Count of {container}”, status pill, meta “Started {date} · {blind ? ‘Blind count’ : ‘Expected shown’}”.
- actions by status: Counting → primary “Complete count”; Completed → “Approve”; Approved → “Apply adjustments” (confirm: “Apply {n} adjustments? Inventory numbers will change.”).
- stats: Lines counted [loaded] · Variances [loaded].
- body: the ScanWorkbench (camera or paste + product/container select + qty + “Record count”) and below it a “Counted so far” list (product, counted, expected if not blind, variance pill).
States: empty counted list: “No counts recorded yet. Scan or pick an item to start.”

Side drawer DetailLayout (drawer presentation): title label, meta code · location, status Active/Inactive, tabs Contents · History · Details.
- Contents: Products (name · available) and Units (asset tag · status pill · inline “Show QR” · [...] Warranty). Sub-containers as chips.
- History: scan rows (time · context · “Reviewed handover” / “QR scan”).
- Details: settings rows Label, Location, Active toggle, Kit components (when kit feature on), Save.
States: Contents empty: “This container is empty.” · History empty: “No scans yet.”

Where: inside the core machine-type page (panels/machine/MachineTypePage.tsx; the page frame is owned by ux-spec.md). Components MachineServiceConsole.tsx, PrinterServiceConsole.tsx.
Reference: org2 tabs + rows, mgr2 inline actions.
Slot fill: the type page’s DetailLayout gets a “Queue” tab (and “Manual usage” and, for printers, “Printer reports” tabs) instead of stacked Subsections.
- Queue tab: sub-tabs Pending · Accepted · Printing (in progress) · Ready (completed) · Failed, each with [loaded] counts. Rows: requester chip · job title · meta “Planned {q} {unit} · actual {q} {unit}” · status pill · one inline next action (Pending → “Accept”, Accepted → “Start”, In progress → “Complete”, Completed → “Hand over”, Failed → “Reprint”). Reject and Fail live in the row [...] in red. The action form (minutes, machine, pool, reason) opens as a dialog titled by the verb (“Start job”, “Complete job”, “Mark failed”) instead of an inline bordered box.
- Manual usage tab: primary “Log usage” (dialog), list of entries (outcome pill · qty · minutes).
- Info line under the tabs (muted): “This type is metered in {unit}.” Pool guidance appears as helper text in the Start dialog.
States: “No jobs waiting. New requests land here.” / “No manual usage logged yet.”
