Results:

  • 61 cases: 60 paired-workbook cases and one directory portfolio case.
  • 63 observable truth facts across 51 block and 10 review cases.
  • Three scoreable coverage expectations: one newly introduced INDIRECT boundary and two unchanged-formula selector changes (INDIRECT address text and OFFSET column displacement).
  • 186 generated fixture files: 124 workbooks, 61 truth manifests, and one JSONL case catalogue, all generated from source.
  • Two hundred ninety-four unit tests passed locally under Python 3.13, including independent regeneration and byte-for-byte fixture-tree equality.
  • The fixture validator accepted all 61 cases.
  • The external-data refresh pair has identical package members except for xl/connections.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its relationship-backed source is a non-routable example.invalid URL.
  • The external-data web-query source pair has identical package members except for xl/connections.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one relationship-backed connection retains ID 1, type 4, name, refreshOnLoad=false, refreshedVersion=1, workbook relationship, content type, saved ImportedData!B2=100 cell, and ImportedData!B2 → Summary!B2 → Dashboard!B4 formula context while raw webPr/@url moves from the reserved approved.example.invalid endpoint to review.example.invalid. The validator compares the connection part after removing only that URL and does not resolve, open, fetch, authenticate to, trust, refresh, calculate, or otherwise interact with either endpoint, or claim a client result.
  • The OPC package-signature Manifest pair has identical package members except _xmlsignatures/sig1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its root-to-origin and origin-to-signature relationships, origin/signature content types, one SignedInfo local-object reference, stable Controls!B10=12 value and Controls!D10=B10*C10 formula, and calculation properties remain fixed while the one Object/Manifest/Reference/@URI moves from the workbook part to the first worksheet part. The generated digest and signature values are synthetic: the validation run does not verify a digest, signature, transform, certificate, identity, trust chain, or consumer decision.
  • The OPC package-signature relationship-selector pair likewise has identical package members except _xmlsignatures/sig1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its root-to-origin and origin-to-signature relationships, content types, SignedInfo local-object reference, Manifest URI, one Relationships Transform immediately followed by XML C14N, stable Controls!B10=12 value and Controls!D10=B10*C10 formula, and calculation properties remain fixed while the sole RelationshipReference/@SourceId selects the root office-document relationship before and the root signature-origin relationship after. The selected relationship is not proof its target part was signed; the validation run does not execute a transform or verify a digest, signature, certificate, identity, trust chain, or consumer decision.
  • The modern threaded-comment resolution pair has identical package members except xl/threadedComments/threadedComment1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one top-level comment keeps its synthetic text, timestamp, identifiers, cell binding, linked person record, content types, worksheet/workbook relationships, stable Controls!B10=12 value, Controls!D10=B10*C10 formula, and calculation properties fixed while raw threadedComment/@done changes from 0 to 1. The validator reads only the bounded local OOXML shape and compares the comment part after erasing that token. It does not expose or assess comment content or identity, prove review or approval, send notifications, authenticate or authorize a person, open a client, or claim workflow completion.
  • The legacy shared-workbook revision-log pair has identical package members except xl/revisions/revisionLog1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its workbook-to-header-to-log graph, content types, tracking/history/retention/protection controls, synthetic header metadata, revision-record shape, stable Controls!B10=12 value, Controls!D10=B10*C10 formula, and calculation properties remain fixed while one private historic value changes. The validator reads only that bounded local OOXML shape and compares the log after erasing the private value. It does not expose or validate historic values, locations, author identity, timestamps, GUIDs, or relationship IDs; verify provenance; replay history; resolve a conflict; prove review/approval; authenticate or authorize a person; or claim workflow/client behavior.
  • The QueryTable pair has identical package members except for xl/queryTables/queryTable1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its direct ImportedData worksheet-to-QueryTable and workbook-to-connections relationships, non-routable example.invalid web-query URL, connection-level refreshOnLoad=false, remaining QueryTable controls, saved ImportedData!B2=100 cell, and ImportedData!B2 → Summary!B2 → Dashboard!B4 formula context are unchanged while raw queryTable/@refreshOnLoad changes from false to true. The validation run did not open a connection, fetch a URL, refresh a query, materialize rows, calculate a workbook, or claim a successful client refresh.
  • The cell-hyperlink target pair has identical package members except for xl/worksheets/_rels/sheet1.xml.rels; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one Inputs!B2 worksheet hyperlink declaration, visible Open vendor portal text, fixed relationship ID/type/TargetMode=External, calculation properties, and Inputs!B2 → Summary!B2 → Dashboard!B4 formula context remain unchanged while raw Relationship/@Target moves from the reserved approved.example.invalid URL to review.example.invalid. The validation run did not resolve, open, fetch, visit, execute, calculate, or otherwise interact with either target, or claim that a client follows one.
  • The external-workbook source pair has identical package members except for xl/externalLinks/_rels/externalLink1.xml.rels; both archives pass ZIP integrity checks and remain readable by openpyxl. Its LinkedModel!B2 formula, direct Dashboard!B4 consumer, calculation properties, workbook external-reference binding, externalLink/externalBook declaration, source sheet name, relationship IDs/types, content type, and TargetMode=External remain unchanged while its one externalLinkPath Relationship/@Target moves from the reserved approved.example.invalid source to review.example.invalid. The validation run read local package parts only: it did not resolve, open, fetch, authenticate to, trust, refresh, calculate, or otherwise interact with either source, or claim a client updates a link or returns a value.
  • The external-defined-name source pair has identical package members except for xl/workbook.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one local ScenarioRate definition moves exactly from '[WCABApprovedSource.xlsx]Inputs'!$B$2 to '[WCABReviewSource.xlsx]Inputs'!$B$2, while Model!B2=ScenarioRate*2, its direct Dashboard!B4 consumer, calculation properties, sheet declarations, and workbook relationships remain unchanged. Neither package has an externalReferences declaration or an xl/externalLinks/ member. The validation run read local OOXML only: it did not resolve, open, fetch, authenticate to, trust, refresh, calculate, or otherwise interact with a source, or claim a client resolves the name or returns a value.
  • The named-LAMBDA definition pair has identical package members except for xl/workbook.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one workbook-scoped ScenarioValue definition moves exactly from =LAMBDA(rate,amount,rate*amount) to =LAMBDA(rate,amount,rate*(amount+10)), while Inputs!B2=0.08, Inputs!B3=100, Model!B2=ScenarioValue(Inputs!B2,Inputs!B3), its direct Dashboard!B4 consumer, calculation properties, sheet declarations, and workbook relationships remain unchanged. Neither package has an externalReferences declaration or an xl/externalLinks/ member. The validation run read local OOXML only: it did not evaluate the LAMBDA body, calculate a workbook, infer Excel-version support, or claim a recalculated, spilled, or persisted result.
  • The Table calculated-column formula pair has identical package members except for xl/tables/table1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one Ledger!A1:C4 ScenarioLedger Table, worksheet-to-Table relationship, headers, tableColumn IDs, autoFilter, raw C2:C4 formulas, calculation properties, and Dashboard!B4=SUM(ScenarioLedger[Calculated amount]) remain unchanged while the raw ID-3 calculatedColumnFormula moves exactly from A2*B2 to A2*(B2+1). The validation run did not fill a calculated column, calculate a workbook, infer stored results, or claim client behavior.
  • The Power Pivot/Data Model relationship pair has identical package members except for xl/workbook.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one x15:modelRelationship moves exactly from SalesModel.CalendarKey → CalendarModel.DateKey to SalesModel.CalendarKey → CalendarModel.FiscalDateKey, while its two local Tables, powerPivotData workbook relationship, .data content type, calculation properties, and fixed opaque xl/model/item.data payload remain unchanged. The validation run read the local declaration and payload digest only: it did not deserialize a model, evaluate DAX, refresh it, calculate or render a report, infer model-to-cell impact, or claim client behavior.
  • The XLM Auto_Open binding pair is a real macro-enabled .xlsm pair with identical package members except for xl/workbook.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one workbook-scoped _xlnm.Auto_Open defined name moves exactly from 'Macro Automation'!$A$1 to 'Macro Automation'!$A$2, while its one very-hidden Macro Automation macro-sheet declaration, workbook relationship, macro-enabled workbook and macro-sheet content types, raw 234-byte xl/macrosheets/sheet1.xml payload, and ordinary Inputs!B2 → Model!B2 → Dashboard!B4 formula context remain unchanged. The payload contains only A1=HALT() and A2=HALT(). The validation run read local OOXML only: it did not open Excel, enable or execute XLM code, parse or emulate macro instructions, resolve a dynamic name, inspect macro-security or trust state, infer an automatic dispatch result, calculate a workbook, or claim client behavior.
  • The sheet-protection sort-permission pair has identical package members except for xl/worksheets/sheet1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its Controls worksheet remains protected, Controls!D2=B2*C2 and its direct Dashboard!B4 consumer remain unchanged, and every other protection action lock, style, and calculation property remains fixed while raw sheetProtection/@sort moves from 1 (locked) to 0 (permitted). The validation run did not test a password, encryption, authentication, authorization, editable ranges, a client sort operation, or a resulting value.
  • The protected-range descriptor pair has identical package members except for xl/worksheets/sheet1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its protected Controls!B2:B2 target remains locked, the range name/reference and legacy verifier stay fixed, and Controls!D2=B2*C2 plus its direct Dashboard!B4 consumer remain unchanged while one standard nested protectedRange/securityDescriptor text changes. The validator privately reads that compact generated element and compares the worksheet after erasing only the descriptor text. Public truth excludes the descriptor, range name, and verifier; the validation run does not test a password or verifier, encryption, identity, authentication, authorization, editable-range enforcement, spreadsheet-client behavior, or a resulting value.
  • The sensitivity-label metadata pair has identical package members except for docProps/custom.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its document custom-property relationship, root classificationlabels relationship, LabelInfo labelList part, ordinary Controls!B2=12 input, Controls!D2=B2*C2 formula, direct Dashboard!B4 consumer, and calculation properties remain fixed while one private MIP custom-property value changes. The validator reads the exact generated relationship/content-type/property envelope privately and compares custom properties after erasing only that value. Public truth exposes only counts and safe package members; the validation run did not resolve a label, contact a policy service, determine effective classification, inspect encryption or permissions, infer access, authenticate an identity, enforce policy, or claim Office, SharePoint, OneDrive, or storage-service behavior.
  • The relationship-bound worksheet-control macro-assignment pair has identical package members except for xl/worksheets/sheet1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one control declaration, one control-properties relationship and Office 2010 properties part, content-type binding, ordinary Controls!B2=12 input, Controls!D2=B2*C2 formula, direct Dashboard!B4 consumer, and calculation properties remain fixed while one private inline macro assignment changes. The validator compares the worksheet after erasing only that assignment. Public truth exposes safe counts and member paths only; the validation run did not load a control, inspect or execute VBA, resolve a macro, authenticate a user, evaluate permissions, invoke an Office client, or claim an event result.
  • The PivotCache pair has identical package members except for xl/pivotCache/pivotCacheDefinition1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its local Source!A1:B5 worksheet binding, Report!A1:B2 PivotTable location, stored display cells, and direct Dashboard!B4 formula are unchanged while raw refreshOnLoad changes from false to true. The validation run did not open Excel, refresh a cache, calculate or render a PivotTable, or infer a report result.
  • The PivotTable aggregation pair has identical package members except for xl/pivotTables/pivotTable1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its local Source!A1:B5 binding, cache records, Report!A1:B2 location, stored report/dashboard cells, direct Dashboard!B4 formula, refresh control, and calculation properties are unchanged while its one dataFields/dataField/@subtotal moves from sum to average. The validation run did not open Excel, refresh, calculate, or render a PivotTable, infer a changed display value, or claim client behavior.
  • The PivotTable Slicer-selection pair has identical package members except for xl/slicerCaches/slicerCache1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its local Source!A1:B5 binding, PivotCache, Report!A1:B2 location, stored report/dashboard cells, direct Dashboard!B4 formula, refresh control, and calculation properties are unchanged while its one selected Region cache item moves from index 0 (North) to index 1 (South). The validator follows the workbook-to- Slicer-cache-to-PivotCache/PivotTable bindings and does not create a visual Slicer, apply a filter, refresh, calculate, render, infer a displayed result, or claim client behavior.
  • The connection-only Power Query pair has identical package members except for customXml/item1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its Source!A1:B5 SourceData Table, worksheet cells, table definition, calculation properties, metadata, and permission controls are unchanged while the stored Table.SelectRows M literal moves from North to South. The validator follows the package-root custom-XML relationship and bounded generated Data Mashup envelope; it does not execute M, apply the filter, refresh a query, materialize output, calculate a workbook, infer returned rows, or claim client behavior.
  • The Scenario Manager pair has identical package members except for xl/worksheets/sheet1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one selected, locked scenario retains its selection/protection, comment/user, summary-reference, second-input, and number-format metadata, plus visible Inputs!B2=0.1, Inputs!B3=125, Inputs!D2=B2*B3, and Dashboard!B4=Inputs!$D$2. Only the raw alternate inputCells/@val for B2 moves from 0.08 to 0.16. The validation run did not show or apply a scenario, calculate a workbook, create a Scenario Summary, infer an output, or claim client behavior.
  • The What-If Data Table pair has identical package members except for xl/worksheets/sheet1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its raw Sensitivity!D3 master keeps ref="D3:D5", ca="1", column orientation, the input grid, ordinary formulas, calculation properties, and saved table results empty while its one r1 input reference moves from B2 to B3. The validation run did not substitute inputs, calculate a workbook or Data Table, infer a table output, resolve a circular dependency, or claim client behavior.
  • The list data-validation source pair has identical package members except for xl/worksheets/sheet1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one Inputs!B2 list rule retains the target range, error/prompt/dropdown metadata, both Lists source columns, current Draft input, ordinary formulas, and calculation properties while raw formula1 moves exactly from =Lists!$A$2:$A$4 to =Lists!$B$2:$B$4. The validation run did not evaluate either source, decide whether a future input is valid, accept/reject an entry, calculate a workbook, or claim client behavior.
  • The conditional-formatting threshold pair has identical package members except for xl/worksheets/sheet1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one Operations!B2:B4 cellIs rule retains its target, priority, greaterThan operator, differential red fill, and stored 10, 75, and 120 metrics while raw formula moves from 100 to 50. The validation run did not evaluate the rule, determine a rendered cell format, calculate a workbook, or claim client behavior.
  • The custom number-format pair has identical package members except for xl/styles.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its one Operations!B2 style index, raw 0.125 value, and neighboring B3=B2 formula remain unchanged while the referenced custom numFmt/@formatCode moves from 0.0%;[Red](0.0%);- to ;;;. The validator compares styles XML after erasing only that code. It does not render a number format, resolve locale or column width, determine a displayed value, calculate a workbook, or claim client behavior.
  • The ignored-error suppression pair has identical package members except for xl/worksheets/sheet1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its Operations!B2=10, B3=20, B4=30, B5=SUM(B2:B3), and C5=B5 records remain unchanged while one standard ignoredErrors/ignoredError declaration with sqref="B5" and formulaRange="1" is added. The validator compares worksheet XML after removing only that declaration. It does not determine whether Excel would show a warning, evaluate the formula, render an indicator, decide whether the warning is justified, calculate a workbook, or claim client behavior.
  • The workbook-structure-protection pair has identical package members except for xl/workbook.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its hidden ReviewControls sheet and Inputs!D2=B2*C2 formula remain unchanged while raw workbookProtection/@lockStructure moves from 1 to 0. The validator compares the workbook XML after removing only that attribute. It did not test a password, encryption, authentication, authorization, exposure of a hidden sheet, or a particular Excel client's sheet-operation behavior.
  • The chart-series pair has identical package members except for xl/charts/chart1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its Dashboard!D2 anchor, title/category references, source cells, and all worksheet parts remain unchanged while raw c:ser/c:val/c:numRef/c:f moves from Source!$B$2:$B$4 to Source!$C$2:$C$4. The validation run did not open Excel, calculate source cells, refresh chart data, render a chart, or infer a visual difference.
  • The external-workbook-link policy pair has identical package members except for xl/workbook.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its unchanged LinkedModel!B2 formula names the absent synthetic WCABSource.xlsx, while workbookPr/@updateLinks changes exactly from never to always.
  • The iterative-calculation pair has identical package members except for xl/workbook.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its unchanged Model!B2 direct self-reference records the same explicit 100 / 0.001 bounds in both workbooks while calcPr/@iterate changes exactly from false to true.
  • The precision-as-displayed pair has identical package members except for xl/workbook.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its stored Inputs!B2=10.005, 0.00 format, formula, and local downstream reference are unchanged while calcPr/@fullPrecision changes exactly from true to false. The validation run did not open, calculate, or save either workbook.
  • The workbook-date-system pair has identical package members except for xl/workbook.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its raw Inputs!B2=45292 numeric serial, yyyy-mm-dd style, local Model!B2 and Dashboard!B4 formulas, and explicit dateCompatibility=true control are unchanged while workbookPr/@date1904 changes exactly from false to true. The validation run did not calculate, convert a serial, predict a displayed date, open, or save either workbook.
  • The active-AutoFilter pair has identical package members except for xl/worksheets/sheet1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its sole raw Report!A1:B5 column-0 list value changes from North to South, while its SUBTOTAL(109,B2:B5) and dashboard formulas remain unchanged. The validation run did not apply a filter, calculate a subtotal, infer a visible row set, or open or save either workbook.
  • The saved Named Sheet View pair has identical package members except for xl/namedSheetViews/namedSheetView1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its Report!A1:B5 worksheet AutoFilter retains no active criterion and its xr:uid binding, rows, Report!D2=SUBTOTAL(109,B2:B5), and Dashboard!B4=Report!$D$2 remain unchanged while the relationship-backed saved view moves its sole column-0 list value from North to South. The validator follows the worksheet relationship, confirms the content type and base-filter binding, and does not activate, render, or apply the view, calculate a subtotal, infer visible rows, or claim a client display or print outcome.
  • The XML Map pair has identical package members except for xl/tables/table1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its synthetic local MapInfo/XSD declaration, file-binding metadata, Export!E2 single-cell mapping, table values, Export!D2=SUM(InvoiceLines[Net amount]), and Dashboard!B4=Export!$D$2 remain unchanged while the mapped table column XPath moves from NetAmount to TaxAmount. The validator follows only local workbook and worksheet relationships and does not access a file, validate a schema, import/export XML, materialize data, calculate a result, or claim client behavior.
  • The Office Web Add-in pair has identical package members except for xl/webextensions/webextension1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its workbook-to-taskpane-to-web- extension relationship chain, synthetic local FileSystem reference, add-in IDs, hidden locked pane, ordinary cells, calculation properties, and Inputs!B2 → Model!B2 → Dashboard!B4 formulas remain unchanged while raw Office.AutoShowTaskpaneWithDocument moves exactly from false to true. The fixture has no manifest payload or external relationship. The validation run did not install, load, execute, or fetch an add-in or manifest, or claim that a task pane opens or that the add-in accesses a workbook cell.
  • The embedded-OLE auto-load pair has identical package members except for xl/worksheets/sheet1.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. It retains one standard direct internal OLE-object relationship, the matching content type, fixed opaque ASCII payload bytes, a synthetic unregistered ProgID, and unchanged Inputs!B2 → Model!B2 → Dashboard!B4 formula context while raw oleObject/@autoLoad moves exactly from false to true. It has no linked target, ActiveX control, presentation, macro, or external relationship. The validation run did not deserialize, open, render, execute, register, or invoke an object server, or claim that any object loads successfully.
  • The saved-formula-result pair has identical package members except for xl/worksheets/sheet2.xml; both archives pass ZIP integrity checks and remain readable by openpyxl. Its direct input, formula expression, calculation properties, and local downstream formula are unchanged while the raw Model!B2 numeric <v> result changes exactly from 20 to 25. The validation run did not calculate, validate, or interpret either result.
  • The array-mode pair preserves the Model!B1 =LEN(Inputs!A1:A3) anchor and its stored B1:B3 range. The candidate adds xl/metadata.xml, one sheetMetadata relationship, one content-type override, and cm=1 on the anchor; both archives pass ZIP integrity checks and remain readable by openpyxl. The raw validator classifies the pair exactly as legacy_cse then dynamic without calculating a value or predicting a spill extent.

Distribution supplement

The 0.44.1 release retains the one-row-per-case manifest.jsonl catalogue and the tool-neutral observation protocol at version 2. Each catalogue row retains the schema-version-3 truth contract and includes byte counts and SHA-256 digests for the workbooks it names.

Results:

  • The source distribution and universal wheel passed twine check.
  • Final wheel and source-distribution SHA-256 values are recorded alongside their uploaded assets in the GitHub release, avoiding a self-referential source-distribution checksum in this record.
  • Fresh Python 3.13 wheel and source-distribution installations both reported version 0.44.1 and validated all 61 fixtures; both emitted byte-identical JSONL output.
  • The full 294-test suite, lint, and format checks passed locally under Python 3.13.
  • The generated unsupported template scored as zero analyzed coverage, zero expected-fact recall, and zero coverage-disclosure recall, confirming that unsupported cases cannot become a pass.
  • The FormulaFence normalizer emitted 62 matched facts, one intentionally unmapped fact, three matched coverage declarations, and no invented review disposition.

FormulaFence reference adapter

FormulaFence 0.225.0 was installed from its released wheel and invoked only against WCAB's generated files:

wcab formulafence --fixtures fixtures --strict

Results:

  • All 62 currently mappable diff/portfolio facts were observed.
  • All three mappable coverage expectations were matched; no mapped fact, coverage expectation, or targeted lint rule was missed across all 61 cases.
  • The schema-version-2 structured Table scope case was observed as a table_definition_changed diff, even though its summary formula text stays unchanged.
  • The WCAB 0.34 named-LAMBDA case was observed as one exact ScenarioValue defined_name_changed record and FF008, including the generated before/after LAMBDA texts. FormulaFence did not expose the package-member boundary or evaluate the name; WCAB independently established the workbook-XML-only difference, stable inputs/formulas, and absence of external-link declarations. Neither report calculated a workbook or claimed a result.
  • The WCAB 0.34 Table calculated-column formula case was observed as one exact table_definition_changed record and high-severity FF013. FormulaFence's redacted profile retained the ScenarioLedger identity, Ledger!A1:C4 scope, headers, and row-count controls while reporting that its calculated column formula materially changed; it did not expose the master text or a package-member boundary. WCAB independently established the exact raw ID-3 formula transition, stable row formulas/dashboard formula, and Table-part-only difference. Neither report filled a column, calculated a workbook, inferred results, or claimed client behavior.
  • The WCAB 0.35 Power Pivot/Data Model relationship case was observed as one exact high-severity power_pivot_data_model_changed record and FF033. FormulaFence's redacted profile retained one internal data part, one workbook binding, one declaration, two model tables, one model relationship, one fingerprinted payload, and no coverage gaps; only its declaration-change flag differed. FormulaFence did not expose model names, relationship keys, DAX, targets, XML, or payload bytes. WCAB independently established the exact raw DateKey-to-FiscalDateKey transition, fixed opaque payload, and workbook-XML-only difference. Neither report deserialized a model, evaluated DAX, refreshed it, rendered a report, inferred model-to-cell impact, or claimed client behavior.
  • The WCAB 0.36 XLM Auto_Open binding case was observed as one exact high-severity xlm_automatic_macro_bindings_changed record and FF076. FormulaFence's redacted profile retained one automatic-macro binding and one Auto_Open binding, with no close/activate/deactivate binding; only its material-change flag differed. It did not expose macro-sheet names, target cells, XML, byte payloads, or package-member boundaries. WCAB independently established the exact $A$1-to-$A$2 stored target transition, fixed byte-identical two-HALT() macro sheet, very-hidden state, fixed relationship/content types, and workbook-XML-only difference. Neither report opened Excel, enabled or executed XLM code, parsed or emulated macro instructions, resolved a dynamic name, inferred dispatch behavior, calculated a workbook, or claimed client behavior.
  • The schema-version-3 introduced-dynamic case was observed as both a dynamic_formula_reference_added diff and FF012 coverage warning.
  • The two WCAB 0.5 dynamic-driver cases were observed as an Inputs!E12 value_changed diff plus a candidate dynamic_reference_cells profile feature at Summary!B2. The adapter preserves that paired evidence as the dynamic_reference_driver_changed declaration; it does not claim to evaluate either selected target.
  • The WCAB 0.6 external-data case was observed as the exact external_data_connections_changed connection-ID-1 refresh_on_load false-to-true transition and FF023. The report omitted the synthetic connection name and endpoint; neither tool opened or refreshed it.
  • The WCAB 0.37 external-data web-query source case was observed as one exact high-severity external_data_connections_changed record and FF023. FormulaFence's before/after profiles retained the same safe one-web-query connection description while reporting source_configuration_material_changed=true and exactly source_material_change_categories: ["web_query_url"]. It exposed neither endpoint, connection string, command, parameter, XML, fingerprint, or package-member boundary. WCAB independently established the reserved URL transition, fixed connection graph/controls/saved cells/formulas, and xl/connections.xml-only boundary; neither report opened, fetched, authenticated to, trusted, refreshed, calculated, or otherwise interacted with a source, or claimed a client result.
  • The WCAB 0.38 OPC package-signature Manifest case was observed as one exact high-severity digital_signature_controls_changed record and FF050. FormulaFence's redacted before/after profiles retained one signature origin, one XML signature, one Manifest direct-part reference, no certificates, no VBA-project signatures, no selectors, and no unrecognized signature evidence while the aggregate direct-part category moved from one workbook part to one worksheet part. It exposed no URI, selector, digest, signature value, certificate, identity, or trust assertion. WCAB independently established the synthetic direct-part URI transition, fixed relationship graph/content types/local-object reference/cells/formula, and _xmlsignatures/sig1.xml-only boundary; neither report verified a digest, signature, transform, certificate, trust chain, or consumer decision.
  • The WCAB 0.39 package-signature relationship-selector case was observed as one exact high-severity digital_signature_controls_changed record and FF050. FormulaFence's redacted before/after profiles were exactly equal: one signature origin, one XML signature, one Manifest relationship reference, zero direct-part references, no certificates, no VBA-project signatures, and no unrecognized signature evidence. Its distinct package_signature_manifest_coverage_changed=true signal still exposed the material retarget. It exposed no URI, selector, digest, signature value, certificate, identity, or trust assertion. WCAB independently established the synthetic root-relationship source-ID transition, required Relationships-Transform-plus-C14N sequence, fixed graph/cells/formula, and _xmlsignatures/sig1.xml-only boundary; neither report executed a transform or verified a digest, signature, certificate, trust chain, or consumer decision.
  • The WCAB 0.40 modern threaded-comment resolution case was observed as one exact high-severity threaded_comment_controls_changed record and FF045. FormulaFence's redacted profile retained one worksheet-bound comment part, one thread/comment/person, no replies or mentions, two internal bindings, and no external or unrecognized metadata while resolved_comment_count moved from 0 to 1 and only its definition-material flag differed. It did not expose text, comment-cell reference, timestamp, relationship ID, comment ID, person ID, or identity data. WCAB independently established the bounded synthetic package graph, stable ordinary cell/formula context, and xl/threadedComments/threadedComment1.xml-only boundary. Neither layer proves review or approval, sends a notification, authenticates or authorizes a person, opens a client, or claims workflow completion.
  • The WCAB 0.41 legacy shared-workbook revision-log case was observed as one exact high-severity shared_workbook_revisions_changed record and FF062. FormulaFence's redacted before/after profile retained one header part/header, one revision-log part, three log records, enabled shared/tracking/history/ retention/protection controls, and no unrecognized metadata while only revision_log_material_changed=true differed. It did not expose historic values, cell locations, author identity, timestamps, GUIDs, or relationship IDs. WCAB independently established the bounded synthetic package graph, stable ordinary cell/formula context, and xl/revisions/revisionLog1.xml-only boundary. Neither layer verifies provenance or identity, replays a revision, resolves a conflict, proves review/approval, authenticates or authorizes a person, or claims workflow completion.
  • The WCAB 0.30 QueryTable case was observed as one exact query_table_refresh_controls_changed record and FF023: FormulaFence's redacted profile retained one ImportedData table, connection ID 1, fixed background/disable/remove/fill/edit/growth controls, name metadata, and no opaque metadata while only refresh_on_load moved from false to true. It did not expose the endpoint, OOXML part, or result rows. WCAB independently established the direct local relationship graph, fixed connection-level control, stable saved cells/formulas, and QueryTable-part-only boundary; neither report opened a connection, fetched a URL, refreshed a query, materialized rows, calculated a workbook, or claimed a client refresh.
  • The WCAB 0.31 cell-hyperlink target case was observed as one exact cell_hyperlink_controls_changed record and FF047: FormulaFence's redacted profile retained one external worksheet hyperlink binding with no location, display, tooltip, or unrecognized declaration while its binding, definition material, and relationship material changed. It did not expose the target or relationship ID. WCAB independently established the exact reserved-target transition, fixed relationship ID/type/mode, stable visible text/formulas, and relationship-part-only boundary; neither report resolved, opened, fetched, visited, or otherwise interacted with a target, or claimed that a client follows it.
  • The WCAB 0.32 external-workbook source case was observed as one exact external_link_packages_changed record and FF025: FormulaFence's redacted profile retained one external workbook and source sheet, no DDE/OLE link, no cached external data, and no opaque metadata while only source_material_changed was set. It did not expose the source target or relationship IDs. WCAB independently established the exact reserved-target transition, fixed external-reference graph, stable formula context, and externalLink-relationship-part-only boundary; neither report resolved, opened, fetched, authenticated to, trusted, refreshed, calculated, or otherwise interacted with a source, or claimed a client updates a link or returns a value. FormulaFence also emitted its generic external_relationships_changed / FF063 diagnostic; the adapter leaves it unmapped because it is not sufficient evidence for this narrower fact.
  • The WCAB 0.33 external-defined-name source case was observed only when both FormulaFence's exact one-surface external_workbook_link_surfaces_changed / FF081 evidence and its exact ScenarioRate defined_name_changed / FF008 evidence agreed on the two generated qualified source expressions. The surface ledger alone is not sufficient. FormulaFence did not expose a package-member boundary; WCAB independently established the exact definition text, absence of an externalLink package and externalReferences declaration, stable formula context, and workbook-XML-only difference. Neither report resolved, opened, fetched, authenticated to, trusted, refreshed, calculated, or otherwise interacted with a source, or claimed a client result.
  • The WCAB 0.33 sheet-protection sort-permission case was observed as one exact sheet_protection_changed record and FF022: its protected Controls profile retained every reported action lock except sort, which moved from locked to permitted. FormulaFence did not expose the raw OOXML attribute or package-member boundary; WCAB independently established the exact sheetProtection/@sort 1-to-0 transition, stable formulas, and worksheet-only difference. Neither report tested a password, encryption, authorization, an actual client sort operation, or a resulting value.
  • The WCAB 0.42 protected-range descriptor case was observed as one exact high-severity protected_range_permissions_changed record and FF022. FormulaFence's equal redacted before/after profiles retained one named range, one legacy verifier, one standard descriptor, and no opaque metadata while only security_descriptor_material_changed=true differed. It exposed no descriptor, identity, range name, or verifier. WCAB independently established the compact nested XML shape, stable locked input/formula path, and worksheet-only package boundary. Neither layer tested a password, encryption, authentication, authorization, editable-range enforcement, a spreadsheet client, or a resulting value.
  • The WCAB 0.43 sensitivity-label metadata case was observed as one exact high-severity sensitivity_label_metadata_changed record and FF118. FormulaFence's equal redacted before/after profiles retained one relevant custom-property part, one standard label-ID property, seven MIP properties, one label ID, one LabelInfo part, one internal LabelInfo relationship, and no malformed or external metadata while only the private custom-property material-change flags differed. It exposed no label ID/name, action/site ID, timestamp, property name/value, XML, relationship ID, or target. WCAB independently established the exact generated package envelope, stable input/formula path, and docProps/custom.xml-only boundary. Neither layer resolved a label, evaluated policy, determined effective classification, inspected encryption or permissions, inferred access, enforced policy, or claimed Office, SharePoint, OneDrive, or storage-service behavior.
  • The WCAB 0.44.1 worksheet-control macro-assignment case was observed as one exact critical worksheet_embedded_controls_changed record and FF029. FormulaFence's equal redacted before/after profiles retained one control sheet, one worksheet control, one form-control-properties part, one control macro assignment, one related relationship, and no ActiveX, OLE, legacy VML, external, or unrecognized surface while only worksheet_control_definition_material_changed=true differed. It exposed no control identity, shape ID, macro name, relationship ID, or raw XML. WCAB independently established the private assignment transition, stable input/formula path, and worksheet-XML-only package boundary. Neither layer loaded a control, inspected or executed VBA, resolved a macro, evaluated permissions, or claimed Office-client behavior.
  • The WCAB 0.14 PivotCache case was observed as one exact pivot_cache_refresh_controls_changed record and FF023. FormulaFence's redacted profile retained one local worksheet cache, ID 1, and all reported controls except refresh_on_load, which changed from false to true; it emitted no parser warning. WCAB's independent raw validation established the source and PivotTable binding, stable stored cells, and cache-definition-only package change. Neither report refreshed or rendered a PivotTable.
  • The WCAB 0.16 PivotTable aggregation case was observed as one exact pivot_table_definitions_changed record and FF031. FormulaFence's redacted profile retained one local cache, one PivotTable, one data field, two cache fields, four cache records, and no auxiliary material while only its PivotTable-layout material changed. It did not expose the source labels, selected aggregate function, or a rendered result. WCAB independently established the local graph, stable stored cells, exact sum-to-average declaration, and PivotTable-part-only package change. Neither report refreshed, calculated, or rendered a PivotTable.
  • The WCAB 0.17 PivotTable Slicer-selection case was observed as one exact slicer_timeline_cache_definitions_changed record and FF032. FormulaFence's redacted profile retained one Slicer cache, one local PivotCache binding, one PivotTable binding, two Slicer items, one selected item, and no timeline or auxiliary material while only its Slicer filter-state/definition flag changed. It did not expose the Slicer name, selected item/value, or a rendered report. WCAB independently established the local graph, stable stored cells, exact index-0-North to index-1-South declaration, and Slicer-cache-part-only package change. Neither report created a visual Slicer, applied a filter, refreshed, calculated, or rendered a PivotTable.
  • The WCAB 0.18 Power Query case was observed as one exact power_query_changed record and FF024. FormulaFence's redacted profile retained one parsed mashup, one formula document, three package parts, one metadata item, connection-only permission controls, and no opaque or embedded content while only formula_material_changed changed. It did not expose M text, local-table values, or a query result. WCAB independently established the local SourceData binding, fixed connection-only controls, exact North-to-South M literal, and custom-XML-part-only package change. Neither report executed M, refreshed a query, materialized output, calculated a workbook, or inferred returned rows.
  • The WCAB 0.19 Scenario Manager case was observed as one exact scenario_manager_changed record and FF035. FormulaFence's redacted profile retained one scenario-bearing worksheet, one scenario, two stored inputs, one selected/locked scenario, one summary reference, one formatted input, and no malformed declaration while only scenario_definition_material_changed changed. It did not expose the scenario name, stored values, input references, comment, or user metadata. WCAB independently established the B2 0.08-to-0.16 raw transition, fixed metadata and visible cells/formulas, plus the Inputs-worksheet-only package change. Neither report showed/applied a scenario, calculated a result, or created a Scenario Summary.
  • The WCAB 0.20 What-If Data Table case was observed as one exact what_if_data_tables_changed record and FF034. FormulaFence's redacted profile retained one Data Table, one column-oriented one-variable table, three declared output cells, one recalculation request, no deleted input reference, and no unrecognized declaration while only its data_table_definition_material_changed flag changed. It did not expose the output range, local input references, or calculated values. WCAB independently established the generated D3:D5 master, exact B2-to-B3 r1 transition, stable input grid/formulas, ordinary static lower bounds, and Sensitivity-worksheet-only package change. Neither report substituted inputs, calculated, resolved a circular dependency, or claimed client behavior.
  • The WCAB 0.21 list data-validation case was observed as one exact data_validation_changed record and FF020. FormulaFence exposed the one Inputs!B2 list rule's source formula and complete entry-control metadata; it did not evaluate either local list or decide whether a future input is valid. WCAB independently established the exact =Lists!$A$2:$A$4 to =Lists!$B$2:$B$4 declaration, stable source values/current input/formulas, ordinary static lower bounds, and Inputs-worksheet-only package change. Neither report accepted/rejected an input, calculated a workbook, or claimed client behavior.
  • The WCAB 0.22 conditional-formatting case was observed as one exact conditional_formatting_changed record and FF021. FormulaFence exposed the one Operations!B2:B4 cellIs rule and raw 100-to-50 formula transition but did not render a workbook or determine which cells receive a format. WCAB independently established the stable priority, operator, differential red fill, metric values, calculation properties, and Operations-worksheet-only package change. Neither report evaluated the rule, calculated a workbook, or claimed client behavior.
  • The WCAB 0.23 custom number-format case was observed as one exact number_format_controls_changed record and FF039. FormulaFence's intentionally redacted before/after profiles each retained one direct-cell custom assignment and no default, row, column, built-in, or unrecognized control while only number_format_definition_material_changed was set. It did not expose a format code or cell target. WCAB independently established the declared code transition, stable target/style/value/formula context, and styles-only package change. Neither report rendered a format, calculated a workbook, or claimed client behavior.
  • The WCAB 0.24 ignored-error case was observed as one exact ignored_error_controls_changed record and FF037. FormulaFence's redacted profile moved from no controls to one standard container, one target range, and one formula-range-omission category with no unrecognized controls, while only ignored_error_definition_material_changed was set. It did not expose the target range or formula. WCAB independently established the generated Operations!B5 target, formulaRange=1 declaration, stable cells/formulas, and worksheet-only package change. Neither report determined whether Excel would show a warning, evaluated a formula, rendered an indicator, or claimed client behavior.
  • The WCAB 0.25 workbook-structure case was observed as one exact workbook_protection_changed record and FF022. FormulaFence's non-secret profile moved from lock_structure=true to all workbook locks false, with no credential or opaque metadata on either side. WCAB independently established the raw lockStructure=1-to-0 transition, stable hidden-sheet/formula context, and workbook-XML-only package change. Neither report tested a password, encryption, authentication, authorization, or client action.
  • The WCAB 0.15 chart-series case was observed as one exact chart_definitions_changed record and FF030. FormulaFence's redacted profile retained one host sheet, drawing, legacy chart, and series; three data references; no chart cache; and no related payloads, while only its chart-definition material changed. FormulaFence did not expose the source formula or a visual result. WCAB independently established the local relationship chain, D2 anchor, title/category references, exact value reference transition, and chart-part-only package change. Neither report calculated or rendered a chart.
  • The WCAB 0.8 external-workbook-link policy case was observed as one exact external_data_refresh_settings_changed transition in FF023: only update_links moved from never to always; allow_refresh_query, refresh_all_connections, and save_external_link_values retained their defaults. The report did not expose the synthetic external formula or open its absent source workbook.
  • The WCAB 0.9 iterative-calculation case was observed as one exact calculation_settings_changed transition in FF009: only iterate moved from false to true; iterateCount=100, iterateDelta=0.001, and the other stored controls stayed unchanged. FormulaFence's direct-self-reference lint surfaced Model!B2 only while iteration was disabled; neither report claims a calculated or converged value.
  • The WCAB 0.10 precision-as-displayed case was observed as one exact calculation_settings_changed transition in FF009: only fullPrecision moved from true to false while the stored input, number format, formula, and other calculation controls remained unchanged. Neither report claims a rounded stored value, calculated result, or client-side save behavior.
  • The WCAB 0.12 workbook-date-system case was observed as one exact workbook_date_system_changed transition and FF117: normalized date1904 moved from false to true while explicit dateCompatibility=true and the unrecognized-control count of zero remained fixed. FormulaFence reported workbook-level evidence only; WCAB's independent raw validation established the stable serial, style, formulas, and package boundary. Neither report claims a converted or displayed date.
  • The WCAB 0.13 active-AutoFilter case was observed as one exact filter_visibility_controls_changed record and FF036: FormulaFence's redacted profile retained one worksheet filter, one filter column, one criterion, and no other visibility controls while its material-definition flag changed. WCAB's independent raw validation established the North-to-South criterion and stable formulas; neither report applies the filter, calculates a subtotal, or claims a visible result.
  • The WCAB 0.26 saved Named Sheet View case was observed as one exact named_sheet_views_changed record and FF038: FormulaFence's redacted profile retained one worksheet, part, named view, filter, column, and criterion; zero sort rules or conditions; and zero unrecognized declarations while only its Named Sheet View material-definition flag changed. It did not expose the view name, IDs, bound range, or list value.

It did not expose the schema, map, XPath, table, or cell values. WCAB independently established the synthetic NetAmount-to-TaxAmount binding transition, stable declarations/formulas, and table-part-only boundary; neither report accessed a file, imported/exported XML, materialized data, or inferred a result.
  • The WCAB 0.28 Office Web Add-in case was observed as one exact office_web_addins_changed record and FF028: FormulaFence's redacted profile retained one declared task-pane part, task pane, web-extension part, and local store reference; one locked hidden task pane; no bindings, snapshots, external relationships, in-content references, or unrecognized parts; and an auto-show count from zero to one. It did not expose add-in IDs, store name, or the property value. WCAB independently established the local relationship graph, false-to-true auto-show property, stable formula context, and web-extension-part-only boundary; neither report installed, loaded, executed, or fetched an add-in or manifest, or claimed that a task pane opens.
  • The WCAB 0.29 embedded-OLE auto-load case was observed as one exact worksheet_embedded_controls_changed record and FF029: FormulaFence's redacted profile retained one worksheet, one embedded OLE object, one internal payload, no linked/external/ActiveX/VML/presentation material, and no unrecognized declaration while its auto-load count moved from zero to one. It did not inspect or deserialize the opaque payload. WCAB independently established the false-to-true attribute transition, fixed relationship and content-type boundary, inert synthetic payload, stable formula context, and worksheet-XML-only package change; neither report opened, rendered, executed, registered, or invoked an object server, or claimed that an object loads successfully.
  • The WCAB 0.11 saved-formula-result case was observed as one exact formula_cached_result_changed record and FF042: FormulaFence reports two formula cells, one numeric saved result, one missing saved result, and exactly one unexplained material cache change. It intentionally omits the raw result values and formula-cell locations, and neither report claims a calculation, stale-cache diagnosis, tampering diagnosis, or displayed value.
  • The WCAB 0.7 array-mode case was observed as the exact Model!B1 legacy_cse-to-dynamic transition with the same stored B1:B3 range and FF018. It reported the declared Dashboard!B2 static impact, emitted no parser warning, and did not expose the fixture formula text in the report.
  • Five targeted lint expectations were observed: copied-formula interruption (FF082), conditional-aggregate range shape (FF093), explicitly unlocked formula cell (FF085), incomplete manual calculation (FF086), and static cycle (FF090).
  • One fact remains intentionally unmapped: the benign structural formula rewrite. It records known before/after locations but does not claim that a generic tool can prove Excel semantic equivalence from this small fixture.

This is a baseline implementation result, not a claim that FormulaFence or any other tool has complete Excel coverage.
