prsd-iws: current-system documentation
The source code was partitioned into work units and analysed. Where a specialist opinion was needed, it was included with the work-unit evidence. The chapters below use that retained evidence to describe the current system and link factual claims to their supporting artifacts.
If an important behavior cannot be established from the available code evidence, its chapter marks a specific Open question for Harten and identifies what would resolve it.
