HCD.15:4.2 - Recover the smallest affected development question

Use a compatible HCD.14 revision hypothesis or equivalent qualified evidence to identify what can change. Preserve unaffected claims, tasks, feedback, support, provider contributions, accessibility arrangements, and specialist boundaries.

Ask which assumption the new condition defeats. A changed AI configuration may reopen independent challenge while leaving source tracing intact. A failed delayed observation may reopen retention without reopening a demonstrated fresh-task contribution. An unavailable specialist may block one later-Work condition without proving a human deficit.

HCD.14 is one admissible supplier, not a compulsory predecessor. Direct holder- and Work-compatible evidence may open HCD.15. When the available evidence supports only one local revision and no continuing trigger or arrangement question remains, stop at HCD.14.
