Basic Memory retired + MemPalace 3.4.0 upgrade plan saved + Brewfile line dropped

Trial verdict (criteria pre-registered in 3f9a89b): false-clean sync report
disqualifies — index stale for same-session writes while status says 'No
changes'. Lessons 7-13 compiled to CM-AI substrate-failure-lessons-2026-06-07
(6cb3fe9). CLAUDE.md conflict-precedence amendment made by steward same
evening. Upgrade plan: backup-first, palliatives acknowledged, migrate-wings
and repair excluded.
