[CLAUDE] Docs: S41 promote-to-disk S37-S40 RAG catch-up chunk (twin-safe before re-bootstrap)

Per AI_INFRA unified at-risk rule (HOLD bootstrap): store_memory chunk 0307141b
(source docs/STATUS.md#s37-s40-catchup) is a synthesized cross-session summary whose
info is scattered across 2 session logs + STATUS but is NOT a clean single twin.
Promote-to-disk verbatim so replace-mode re-bootstrap reproduces it from a corpus file.

5/5 store_memory accounted: 3 broadcasts (disk-twinned) + 16a6b6db (RAG-AUDIT-RESPONSE
twin-safe) + 0307141b (this file, promoted). No data loss on re-bootstrap.

+# SOLUTION_ERP S37-S40 catch-up (RAG content-gap fill, 2026-05-29)
+
+> **Promote-to-disk note (S41, 2026-05-29):** This file is the on-disk twin of RAG store_memory chunk `0307141b` (orig source_path `docs/STATUS.md#s37-s40-catchup`). Promoted to a real corpus file per AI_INFRA's unified at-risk rule — the consolidated summary's information is scattered across `2026-05-29-S36-S39-*.md` + `2026-05-29-S40-*.md` + STATUS.md, but was NOT a clean single twin, so it is preserved verbatim here to survive replace-mode re-bootstrap. Content below = chunk content verbatim.
