स्फुरँ सञ्चलने (०६.०१२१) - nic kartari lung - should be अपुस्फरत् instead of अपिस्फरत् #128

Here the abhyasa will be स्फुर् not स्फार् by स्थानिवत्भाव. After this the derivation is similar to the other form, अपुस्फुरत्, where आत्व is not the applied.

vidyut-prakriya broadly has two kinds of errors: errors that are surface-level and issues that are fundamental.

I think this is a fundamental issue. The problem is how to properly track स्थानिवद्भाव throughout the system.

I believe there is a better workaround here, but I'm not sure which rules count for स्थानिवद्भाव and which don't.

To understand what we do currently, see how maybe_save_sthanivat and force_save_sthanivat are used throughout the code as a hacky workaround. These both write to the sthanivat field on Term. Based on this, maybe you and I can find a better approach.
