the weekly freshness audit, and its reporter's write scope

Maintainer ruling, taken in conversation on 2026-10-30. A scheduled workflow audits the derived layer against the research structure weekly: every merged pull request has a digest, every round is carried by one or allowlisted, the concept registry's terminal goals and the program frame's roots match both ways, every substantive wiki page backs a concept, and every line is referenced by the registry (tests/freshness.py, with its null-input self-test). Findings are filed on the standing issue Freshness audit by a job holding issues: write under the Security section's five conditions, on the pin-bump pattern; the audit gates no merge. A finding is a request for a round — the answer to drift is dispatched curation, never silent automation of content.
