WA-VERIFY-102: Audit BigDecimal.new usage (Ruby 3.x)

[kitcommerce]

Summary

Audit for removed BigDecimal constructor API usage (BigDecimal.new). Ruby 3.x removes/changes deprecated constructors, and this commonly breaks upgrades.

Approach

Run detection:

cd /Users/Shared/openclaw/projects/workarea-modernization/repos/workarea
rg -n "\\bBigDecimal\\.new\\b" core admin storefront | head -n 200

Objective

• Confirm Workarea does not call BigDecimal.new.
• If present, replace with a supported constructor (BigDecimal(...) or BigDecimal("...")), preserving behavior.

Client Impact

None expected (internal numeric conversion behavior should remain correct).

Acceptance Criteria

• All BigDecimal.new call sites audited
• Deprecated calls replaced with supported BigDecimal constructors
• Add/adjust tests where conversion/rounding behavior is sensitive

Verification Plan

• Run targeted tests.
• Re-run detection and confirm no remaining matches.
