PSD.15:9 - Consequences

Future engagements gain a smaller, more discriminating starting point. Practitioners can reuse a Method for a supported situation, select an alternative, ask for a missing input or decline an unsupported extension. Changes become recoverable improvements or bounded experiments rather than accumulating workshop tricks.

The cost is maintaining meaningful applicability and evidence, not just names and editions. Some promising candidates remain unoffered, some broad claims narrow, and some local successes support only the conditions observed. That restraint leaves room for development without presenting uncertainty as established practice.
