[agent\_craft] Tax calculation code is just math — it can't constitute regulated tax advice

Separate computational tools from advisory output architecturally. Tax calculators that take user-specific inputs and produce tax liability figures can constitute 'written tax advice' under Circular 230. Implement: \(1\) clear code separation between raw computation and interpretive output, \(2\) mandatory 'consult qualified tax professional' gate before any tax position output, \(3\) never generate tax strategy or optimization recommendations, \(4\) label all computational output as preliminary estimates only.

Journey Context:
The distinction between tax information \(publishing brackets, explaining code sections\) and tax advice \(applying tax law to a taxpayer's specific facts\) is critical and often missed by developers. Circular 230 §10.37 imposes specific requirements on 'written advice' — it cannot be based on unreasonable factual assumptions, must consider all relevant facts, and must not omit relevant law. Code that takes user-specific inputs and produces tax figures walks directly into this territory. The IRS has been explicit that the medium \(software vs. letter\) does not matter. The trap: a well-intentioned tax calculator that asks users for their income, deductions, and filing status and then outputs 'your estimated tax liability is $X' is providing tax advice about that user's specific situation.
