 - Planning workbench dispatch upgrade with station load summaries, readiness scoring, release-ready and blocker filters, richer planner rows, and inline release/build/buy actions
 - Manufacturing finite-capacity slice with station daily capacity, parallel capacity, working-day calendars, calendar-aware operation scheduling, and operation-level rescheduling from the work-order detail page
 - Manufacturing station edit support for working days, active state, queue, and capacity settings directly from the manufacturing screen
+- Operation execution controls on work orders, including start/pause/resume/complete actions, labor posting, and actual-minute rollups by operation and work order
+- Operation operator assignment and timer-based labor capture, with timer stop posting elapsed minutes back as labor entries
 - Workbench rebalance controls for operation rows, including planner-side datetime rescheduling, quick shift moves, and heatmap-day targeting without leaving the dispatch surface
 - Workbench station-to-station rebalance so planners can move an operation onto another active work center and rebuild the downstream chain from the same dispatch surface
 - Workbench drag scheduling in station grouping mode, with draggable operation cards, station drop targets, heatmap-day-aware drop timing, and projected post-drop load cues before the move is committed
+- Workbench station cards now show planned-vs-actual load so planners can compare schedule intent against recorded execution time
 - Project milestones with status, due dates, notes, and edit-time sequencing inside the project workflow
 - Project-side milestone and work-order rollups surfaced on project list and detail pages
 - Inventory SKU master builder with family-level sequence codes, branch-aware taxonomy management, and generated SKU previews on the item form
