 # Changelog
 
+## 0.28.0 — 2026-08-03
+
+- Add a deterministic, relationship-backed Office Web Add-in task-pane case.
+  Its synthetic local add-in reference, locked hidden task-pane declaration,
+  and ordinary `Inputs!B2 → Model!B2 → Dashboard!B4` formula context remain
+  fixed while `Office.AutoShowTaskpaneWithDocument` changes from false to
+  true.
+- Add the exact `office_web_addin_auto_show_enabled` fact, a narrow
+  raw-OOXML relationship-graph validator, web-extension-part-only package
+  isolation check, and corruption regressions. WCAB records a stored request
+  only: it does not install, load, execute, or fetch an add-in or manifest,
+  and it does not claim that a task pane opens.
+- Extend the optional FormulaFence adapter to require its exact redacted
+  `office_web_addins_changed` profile and high-severity `FF028`, while
+  WCAB independently establishes the generated local reference, auto-show
+  transition, stable workbook context, and package boundary.

 ## 0.27.0 — 2026-08-03

+## Office Web Add-in auto-show requests change workbook behavior outside cells
+
+Microsoft's [Excel auto-open task-pane guidance](https://learn.microsoft.com/en-us/office/dev/add-ins/excel/pnp-open-in-excel)
+documents the `webextension` and `taskpanes` package parts used to associate
+a workbook with an Office Add-in. Its deployment caveat is important: an
+association is only honored when the referenced add-in is already installed,
+sideloaded, or deployed. The [MS-OWEMXML
+specification](https://learn.microsoft.com/en-us/openspecs/office_file_formats/ms-owemxml/4b94ac5d-a8df-44f4-8433-81d43e35a2d7)
+defines the `Office.AutoShowTaskpaneWithDocument` extension property. A
+workbook can therefore acquire a stored request to show an add-in task pane
+without a worksheet-cell diff, and without the package containing an add-in
+manifest or payload.
+
+WCAB 0.28 isolates that declaration in one original synthetic package. It has
+one local workbook-to-taskpane-to-web-extension relationship chain, one hidden
+locked task pane, and one synthetic FileSystem store reference. Its
+`Office.AutoShowTaskpaneWithDocument` value alone moves from false to true;
+the reference, IDs, task-pane layout, ordinary cells, calculation properties,
+and `Inputs!B2 → Model!B2 → Dashboard!B4` formula context remain unchanged.
+The validator follows only local package relationships, compares the
+web-extension XML after erasing that value, and requires that part to be the
+sole package change. The fixture has no manifest payload or external
+relationship. It does not install, load, execute, or fetch an add-in or
+manifest, and it does not claim that any client opens a task pane or that the
+add-in accesses workbook cells.

+## Office Web Add-ins
+
+Microsoft's [workbook auto-open guidance](https://learn.microsoft.com/en-us/office/dev/add-ins/excel/pnp-open-in-excel)
+documents the package parts needed to associate a workbook with an Office
+Add-in and notes that the add-in must already be installed, sideloaded, or
+deployed before an application can honor the association. The
+[MS-OWEMXML specification](https://learn.microsoft.com/en-us/openspecs/office_file_formats/ms-owemxml/4b94ac5d-a8df-44f4-8433-81d43e35a2d7)
+defines `Office.AutoShowTaskpaneWithDocument` as an extension property. That
+makes the stored request reviewable independently of any installed client
+state or executable add-in payload.
+
+The WCAB Office Web Add-in pair has one workbook-to-`taskpanes.xml` relation
+and one taskpane-to-`webextension1.xml` relation. It keeps the synthetic
+local FileSystem reference, add-in/reference IDs, hidden locked task-pane
+layout, `Inputs!B2=10`, `Model!B2=Inputs!$B$2*2`, and
+`Dashboard!B4=Model!$B$2` fixed. Only the web-extension property changes:
+`Office.AutoShowTaskpaneWithDocument` is `false` in the baseline and
+`true` in the candidate. The raw validator follows only those local
+relationships, erases only that property value for comparison, and requires
+`xl/webextensions/webextension1.xml` to be the sole changed package member.
+There is no manifest payload or external relationship. The benchmark does not
+install, load, execute, or fetch an add-in or manifest, and it does not claim
+that a task pane opens or that the add-in reads, writes, calculates, or
+displays workbook cells.
