Combined PRD + ADR for wiring MemPalace (local-first AI memory) into the
GSD loop as an ADR-857 feature capability. Bidirectional sync, three
selectable memory-relationship modes (augment/kg_backend/replace),
loop-point recall+capture map, opt-in tier:full, MCP-primary/CLI-fallback.
Marked Pre-Proposal: the first-party-plugin proposal standard is not yet
established and ADR-857 phase-6 loop wiring is pending. First of a planned
series; PRD/ADR format is provisional pending PM-method evaluation.
