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).

 | 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/) |

+# Quick Task 260526-tcf: Fix Companion Toolbar 1x9 Grid Test Columns — Summary
+
+One-liner: Two pre-existing column assertions in `TestFastSenseCompanion.m` were stale against the post-PR-#159 1x9 toolbar grid; updated them to expect Wiki at col 7 and Settings gear at col 9 (was 6 / 8), matching the production layout in `FastSenseCompanion.m`.
+
+## What Was Built
+
+A two-line correction to two test assertions:
+
+| Test method                                | Asserted column (before) | Asserted column (after) | Source-of-truth |
+| ------------------------------------------ | ------------------------ | ----------------------- | --------------- |
+| `testToolbarHasWikiButton`                 | 6                        | **7**                   | `FastSenseCompanion.m:410` (`hWikiBtn_.Layout.Column = 7`) |
+| `testToolbarGearMovedToColumn8`            | 8                        | **9**                   | `FastSenseCompanion.m:423` (`hSettingsBtn_.Layout.Column = 9`) |
+
+Diagnostic-message text on the same `verifyEqual` calls was updated in lockstep so any future failure reports a coherent expected-column.
+
+## Root Cause
+
+Commit `e2ded77` ("post-second-merge cleanup — Wiki Browser lint + 1x9 toolbar tests") migrated `TestFastSenseCompanionPlantLogToolbar.m` to the new 1x9 layout established by PR #159, but missed the two matching assertions in `TestFastSenseCompanion.m`. The production source (`FastSenseCompanion.m` lines 313–324) defines the canonical 1x9 grid:
+
+```
+col 1 = Events     col 2 = Live        col 3 = Tags    col 4 = Plant Log…
+col 5 = Tile       col 6 = Close all   col 7 = Wiki    col 8 = flex spacer (1x)
+col 9 = Settings gear
+```
+
+The two tests still expected the pre-merge layout where Wiki sat at col 6 and gear at col 8.

+
+## Automated Test Results
+
+⚠️ Verification deferred to the user's local MATLAB session — the `mcp__matlab__*` tools route to the user's MATLAB instance, which is not reachable from this remote sandbox.
+
+Expected outcome when the user runs `mcp__matlab__run_matlab_test_file` on `tests/suite/TestFastSenseCompanion.m`:
+
+- Before this commit: **2 failures** (`testToolbarHasWikiButton`, `testToolbarGearMovedToColumn8`) — both assert outdated columns.
+- After this commit: **73/73 PASS** (or 74/74 if the parallel quick task `260526-r9x` PerTag commit landed on this branch first).
+
+## User Verification Result
+
+Pending — user will run the test file locally and confirm the two failures clear without regressing the other 71 cases.
+
+## Design Decisions
+
+1. **Column-value fix only.** Method name `testToolbarGearMovedToColumn8` retained — user explicitly chose the minimum-diff option to avoid grep-based reference churn. Rename to `testToolbarGearAtColumn9` is deferred to a separate cleanup commit.
+2. **Diagnostic messages updated alongside the assertion values.** The trailing string arg to `verifyEqual` is part of the same call site as the column literal; leaving `'should sit in column 6'` while asserting `7` would print a misleading failure message. This is not a "method-name identifier" change so it falls inside the user's "two-line verbatim" instruction.
+3. **Line-1194 docstring corrected (`column 6` → `column 7`); line-1207 docstring left as-is.** A post-fix audit sweep (`grep -rE "Layout\.Column,\s*[0-9]|column [0-9]" tests/suite/TestFastSenseCompanion*.m`) found the line-1194 header comment was still stale. It is decoupled from the method name (`testToolbarHasWikiButton` has no column number), so it was corrected — same defect class as the assertion, zero rename risk. Line 1207 (`...lives in column 8`) is deliberately *not* touched: it mirrors the method name `testToolbarGearMovedToColumn8`, and keeping the name+docstring as a coherent (stale) pair until the rename lands is cleaner than a `MovedToColumn8` ↔ `column 9` self-contradiction. The same audit confirmed `TestFastSenseCompanionPlantLogToolbar.m` is fully consistent with the 1×9 grid (Plant Log at col 4 on lines 187/345; gear at col 9 on line 219 — independently corroborating the gear-at-9 fix from a second file) and that no other stale column *assertions* exist anywhere.
+
+## Out-of-Scope Follow-ups (not done, deliberately)
+
+- **Rename `testToolbarGearMovedToColumn8` → `testToolbarGearAtColumn9`** — explicit user deferral; should ship as a separate cleanup task that also touches the method header docstrings on both methods.
+- **Audit sweep — DONE (clean).** Ran `grep -rE "Layout\.Column,\s*[0-9]|column [0-9]" tests/suite/TestFastSenseCompanion*.m`: no stale column *assertions* remain in either file. `TestFastSenseCompanionPlantLogToolbar.m` is fully consistent with the 1×9 grid (Plant Log col 4, gear col 9). The only residual is the line-1207 docstring, deliberately deferred to the rename (see Design Decision 3).
+
+## Deviations from Plan
+
+None. Briefing was followed verbatim; only the line numbers (1261/1273) differed from the current file state (actual: 1202/1214) — content matched exactly and the fix was unambiguous.
+
+## Self-Check: PASSED
+
+Verified all claimed artifacts:
+
+- `tests/suite/TestFastSenseCompanion.m` lines 1202–1203 now expect column 7 — confirmed via `git diff`.
+- `tests/suite/TestFastSenseCompanion.m` lines 1214–1215 now expect column 9 — confirmed via `git diff`.
+- `libs/FastSenseCompanion/FastSenseCompanion.m` lines 410 and 423 are the source-of-truth — Layout.Column = 7 (Wiki) and Layout.Column = 9 (gear).
+- Working tree shows exactly 4 line-pair changes inside a single file, matching the design-decision scope.
