Calc-error reports
If a calculation disagrees with HMRC's published rule (PTM for pension, IPTM for bond), email hello@paraplanai.co.uk with:
- The run ID (visible at the top of the compliance annex).
- The HMRC reference you're testing against (PTM / IPTM chapter, or a worked example URL).
- Optionally, what you expected vs what you got.
Calc-error reports are re-derived against the HMRC corpus before reply; you'll get either a fix-and-redeploy date or a citation showing why the engine is right.
