After widget realization w.hPanel points to the inner content panel; rerenderWidgets was only deleting that and leaving the outer cell + WidgetButtonBar chrome alive on the canvas, stacking up zombies across multiple rerenders that painted over switched-to pages. Now deletes the outer cell (hCellPanel) properly. Canvas children stay constant at 29 across 4 rerenders + resize + tab switch.

-Last activity: 2026-05-13 - Completed quick task 260513-q7w: Debounced two-pass post-resize refresh. Initial commit 577bf95 added the ResizeDebounceTimer + cheap update()/refresh() sweep (mirrors SliderDebounceTimer). User reported "still white at very small window sizes" — so follow-up 99c8808 made the refresh callback two-pass: pass 1 = cheap update(); pass 2 = detect any FastSenseWidget whose first line has empty XData but whose Tag has samples (the visible "white" symptom), then escalate to per-widget refresh() and, if still white, to engine-level rerenderWidgets(). Synthetic test on the live demo: forced XData=[] on a real widget's line (941→0), refreshActivePageWidgetsAfterResize_ restored it (0→941). test_dashboard_time_sync_all_pages 5/5 PASS, test_dashboard_range_selector_integration 2/2 PASS.

 | 260513-ovt | Preserve widget X and Y views across Live ticks + Follow toggle reaches every page — (1) added LiveViewMode='follow' guard inside FastSenseWidget.autoScaleY_, (2) removed `autoScaleY_(y)` from FastSenseWidget.refresh/update, (3) removed `broadcastTimeRange(tStart, tEnd)` from DashboardEngine.onLiveTick, (4) flipped FastSenseWidget.LiveViewMode default 'reset'→'preserve', (5) made FastSenseToolbar.syncFollowState public so FastSense.onXLimChanged's auto-disengage hook actually syncs the Follow button, (6) made DashboardEngine.{allPageWidgets,activePageWidgets} public + onFollowToggle uses allPageWidgets() so Follow actually flips every FastSenseWidget across all pages on multi-page dashboards (was silently no-op via swallowed MethodRestricted). Live mode is now strictly "append data only"; Follow does width-preserving slide with 2% right-edge gap. test_fastsense_follow_toggle 10/10, test_dashboard_time_sync_all_pages 5/5, test_dashboard_range_selector_integration 2/2; verified end-to-end on industrial plant demo (Follow ON: XLim+0.140d toward tail, width preserved exactly, 2/2 widgets switched; OFF: 2/2 reverted) | 2026-05-13 | 498a5f3, ca5be95, 8d41c48, 63cdff4 | — | [260513-ovt-when-follow-button-is-pressed-y-axis-lim](./quick/260513-ovt-when-follow-button-is-pressed-y-axis-lim/) |
 | 260513-q7w | Debounced post-resize refresh + ZOMBIE-PANEL fix that stops widgets going white during drag-resize and tab switching — TWO parallel timers on every figure resize event (300 ms cheap two-pass refresh + 1.2 s unconditional rerenderWidgets backstop). switchPage cancels both timers AND waits up to 3 s for in-flight rerenderWidgets to complete before mutating state. `IsRerendering_` flag prevents rerender-cascade scheduling. Re-entrancy guard aborts instead of self-rescheduling. **Root-cause fix**: rerenderWidgets now deletes the OUTER cell panel (via hCellPanel, falling back to hPanel for pre-realization widgets) — previous code deleted only `hPanel` which after realization points to the INNER content panel, leaving the outer cell + its WidgetButtonBar chrome alive on the canvas as "zombies" that stacked up over multiple rerenders and painted over freshly switched-to pages. test_dashboard_range_selector_integration 2/2, test_dashboard_time_sync_all_pages 5/5; canvas-children-count canary verifies zero zombie accumulation across 4 rerenders + resize + tab switch (constant 29) | 2026-05-13 | 577bf95, 99c8808, 4eda604, bc305dc, 54d5aa0, 20bcd4c | — | [260513-q7w-during-dashboard-figure-resize-fastsense](./quick/260513-q7w-during-dashboard-figure-resize-fastsense/) |
+| 260513-sfp | Add auto-y-limit control buttons (V/A/L) to FastSenseWidget WidgetButtonBar — new YLimitMode property (auto-visible / auto-all / locked, default 'auto-visible' reproduces pre-260513-sfp behaviour), setYLimitMode public method (clears UserZoomedY on explicit click so click re-engages autoscale), autoScaleY_ refactored to dispatch on mode AFTER existing precedence guards (YLimits pin / UserZoomedY / FastSense.LiveViewMode=='follow') so 260513-ovt Follow semantics are preserved. DashboardLayout duck-types widget chrome via ismethod(widget,'setYLimitMode'), so future widgets that expose Y-rescale modes opt in without touching DashboardLayout. ASCII glyphs (V/A/L) match existing Info/Detach. reflowChrome_ re-anchors on resize. toStruct omits the default so legacy dashboards stay diff-invisible. test_fastsense_widget_ylimit_modes 11/11, test_fastsense_widget_tag 7/7, test_fastsense_follow_toggle 10/10, test_dashboard_time_sync_all_pages 5/5. Verified on live industrial-plant demo, all 8 scenarios approved. Known caveat: V/A/L cluster butts against Info button (0-px gap) — inherited from pre-existing addInfoIcon 28-px-typo, explicitly out-of-scope per plan; logged in deferred-items.md | 2026-05-13 | 4db9138, cc18c7f, a9cc181 | Verified | [260513-sfp-add-auto-y-limit-control-buttons-to-fast](./quick/260513-sfp-add-auto-y-limit-control-buttons-to-fast/) |
