…em capping, and topics Records measured facts for session takeover hardening: - 17,649 / 756,602 messages (2.33%) have all-digit hex uuid8 refs - 134 system prompt topic segments across corpus, max 41,669 chars - Single-session topic spine retrieval pattern
…1-D3) - D1 (types, read): pure deletion of reNumericRef under Doctrine Rule 4, eliminating 2.33% false reject rate on decimal hex uuid8 refs. - D2 (view): cap non-conversational system anchors to dispCap with policy measurement in docs/design/takeover-path-measurements.md. - D3 (topics, cmd_topics): direct ordered stream of session topic segments from store without custom in-memory filters.
