 Plan: 6 of 6 executed (with 03/04 deferred per Plan 02d data). Shipped plans: 01, 02, 02b, 02d, 05, 06.
 Milestone: v3.0 FastSense Companion — SHIPPED 2026-04-30; v4.0 Multi-User LAN Concurrency — shipping via PR #152 (parallel branch); v1.0 perf line tracks phase 1028 — now COMPLETE via PR #114.
 Status: Phase 1028 closed. WithIO `tickMin` reduced 4497 ms → 3603 ms (−19.9%) on Octave Linux x86_64 CI run 26089658442, almost entirely from Plan 02d's in-memory prior-state cache. Plan 06 ships per-tick fs-stat coalescing reducing 1600 → 1 syscalls/tick (−99.94% mechanism-level; wall-time +3.2% within variance on tmpfs CI). PR #114 carries the phase. Follow-up candidates for a future perf phase: in-memory propagation refactor; `containers.Map` → struct-array refactor; `.mat` save-side optimization. K2/K3/K4 deferred per data (target regions bucket as 0 ms post-cache).

 | 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/) |

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.

 | 260513-s0y | Add Tile + Close all buttons to FastSenseCompanion top toolbar — private OpenedFigures_ tracking + syncOpenedFigures_ (walks Engines_ before tile/close-all) + public trackOpenedFigure hook (InspectorPane.onOpenDetail_ and CompanionEventViewer.openEventDashboard_ forward their figure handles). tileOpenedWindows: ceil(sqrt(N))×ceil(N/cols) grid on monitor containing the companion, 24px margin, 8px gutter, row-major top-down. Before set(Position), coerces each figure to WindowState='normal' + Units='pixels' — root cause of initial "Tile does nothing" report was DashboardEngine.render defaulting to Units='normalized' (pixel rects got treated as screen fractions, pushing figures off-canvas). closeAllOpenedWindows: snapshot + close(h) per handle (honors each figure's CloseRequestFcn). Inner toolbar grid 1×4→1×6 (Events / Live / Tile / Close all / spacer / gear; gear Layout.Column 4→6). 9 sub-tests in test_companion_tile_close_buttons.m PASS; TestFastSenseCompanion regression 64/64 PASS.

 | 260519-bs4 | Add Tag Status Table window to FastSenseCompanion — new `TagStatusTableWindow.m` (classical figure, not uifigure, per CONTEXT.md), opened via new **Tags ↗** button on companion top toolbar (col 3 in the post-merge 1×7 grid: Events / Live / Tags / Tile / Close all / spacer / gear). Detached-only window with 12-column `uitable`: Key, Name, Type, Criticality, Units, Latest, Status (smart per-type — Monitor→OK/ALARM, State→state label, others→—), Last updated (X(end) timestamp), Activity (Live/Inactive at 5-min threshold), Events (count from EventStore), Samples, Labels. All 18 demo tags listed (snapshot from `TagRegistry.find(@(t)true)`). Two parallel refresh paths: (a) push-on-write via existing `FastSenseCompanion.scanLiveTagUpdates_` → `markStatusTableDirty_(keys)` when companion is in Live mode, (b) window-owned `RefreshTimer_` (1s fixedSpacing, unique UUID name, BusyMode='drop', self-stop after 2 consecutive tick errors) so the table refreshes regardless of companion's IsLive — addresses user feedback that Activity/Last updated must stay correct when companion is idle. Pause/Resume polling toggle freezes both paths (markTagsDirty becomes a no-op while paused; header shows "Last refreshed: HH:MM:SS (paused)"). "Last refreshed" heartbeat label updates every tick. Filter chips mirror TagCatalogPane pattern: Type (Sensor/Monitor/Composite/State/Derived), Criticality (Low/Medium/High/Safety), Activity (Live/Inactive) — multi-toggle, AND-across-groups / OR-within-group; broadened free-text search across Key+Name+Units+Labels. Push-on-write hook in companion stays — both mechanisms run in parallel. Six atomic commits + 1 merge: 01 base class + 11 pure-logic tests; 02 companion wiring + 7 lifecycle tests; 03 Activity column + own timer (+5 logic + 2 lifecycle tests, deviation from "push-on-write only" CONTEXT decision per user); 04 last-refreshed header + chip filters + broader search (+4 logic + 2 lifecycle tests); 05 Pause/Resume polling toggle (+4 lifecycle tests); 06 Events count column (+4 logic + 1 lifecycle test); 07 merge with main (PR #143 toolbar grid conflict). Final test counts post-merge: `test_companion_tag_status_table` 24/24 (pure-logic), `TestTagStatusTableWindow` 16/16 (UI lifecycle), `test_companion_tile_close_buttons` 9/9 (main's new test still PASS), `TestFastSenseCompanion` 64/64 (no regression) = 113/113 total. Verified end-to-end on live industrial-plant demo: 4 MonitorTags showed real event counts (29/32/33/35), 14 others showed 0; Activity flipped Live→Inactive at exactly 5-min boundary via static buildRow_ proof; companion IsLive=0 throughout (window polled itself). Deferred / out-of-scope: (1) polling-scope clarification dismissed by user (heartbeat-only vs. passive-observation vs. only-update-changed-cells — left as-is, table updates all cells every tick); (2) Info button + markdown help — scoped up to a milestone-sized "unified in-app help/wiki" effort, parked as backlog 999.1. | 2026-05-19 | b2ed937, e8a1be5, 43d2d3b, 2a24965, 50d464c, 10df740, 73a3bf1 | Verified | [260519-bs4-implement-a-new-table-view-in-the-compan](./quick/260519-bs4-implement-a-new-table-view-in-the-compan/) |
