Workbook Architecture¶

Tab list (must map to individual files in tab-specifications/; order reflects intended left-to-right tab order):

Order	Tab ID	Tab Name	Purpose (one line)	Visible to End User?
1	[TAB-ID]	[e.g. Start Here]	[purpose]	[Yes/No/Hidden]
2	[TAB-ID]	[e.g. Inputs]	[purpose]	[Yes/No/Hidden]
3	[TAB-ID]	[e.g. Calculations]	[purpose]	[Yes/No/Hidden]
4	[TAB-ID]	[e.g. Dashboard]	[purpose]	[Yes/No/Hidden]

Separation of concerns: [Confirm data entry, calculations, and outputs live on distinct tabs per the workbook-architecture standard, and describe how this product's tab list implements that separation.]

Naming pattern: [e.g. tabPrefix_fieldName, all camelCase, no spaces]
Scope policy: [workbook-scoped vs. worksheet-scoped — state the rule and when each is used]
Reserved prefixes: [list any reserved prefixes, e.g. cfg_ for configuration values, calc_ for calculated values]

Sheet protection: [which tabs are protected, which cells within a protected tab remain unlocked for input]
Workbook structure protection: [locked/unlocked, password policy — note: do not rely on Excel sheet protection as a security boundary; state that explicitly]
Formula/IP protection rationale: [what protection is meant to achieve — error prevention vs. formula concealment — and its limits]

Print areas defined: [which tabs have defined print areas]
Page setup: [orientation, scaling, margins per tab, consistent with report-specification.md]

Primary target: [e.g. Excel 365 desktop]
Secondary targets: [e.g. Excel 2019+, Excel for Mac, Excel Online — state limitations for each]
Explicitly unsupported: [e.g. Google Sheets import, older Excel versions — state why]
