      "description": "How MemPalace relates to MSD native memory during recall/capture. 'augment' (default): the palace is an additive layer alongside .planning/graphs/ — native memory stays authoritative. 'kg_backend': knowledge-graph queries resolve against the palace's temporal KG as the primary source, with .planning/graphs/ as fallback. 'replace': recall resolves through the palace as the source of truth, native memory as fallback. Every mode stays onError:skip and default-resilient — an unreachable palace degrades to native memory, and MSD keeps writing .planning/graphs/ so no memory is lost. Cross-mode migration of existing .planning/graphs/ into the palace is a separate, not-yet-implemented concern."
