SYSE.19:3 - Forces

Recurring tensions include:

  • Revalidation should stay bounded, while an undeclared reliance can matter more than a declared trace link.
  • Source identity must remain recoverable without turning every carrier change into a semantic event.
  • One changed sentence can alter release; a large rewrite can leave the relied-on premise intact.
  • Automated search can find candidate uses, while materiality and applicability still need engineering judgement.
  • A newer official or popular source can fit the use worse than an older bounded source.
  • Preserved decisions remain usable only when the reason for preservation is recoverable when later Work needs it.
