mm_index

Rebuild or health-check the ledger semantic embedding index (.mm/index/ledger/, used by mm_search’s hybrid mode and mm_retrieve_prior_work), and/or rebuild the markdown-derived projections .mm/index/specs.json and .mm/index/decisions.json. mode (“rebuild” | “health”) selects the ledger operation and is omitted to skip the ledger entirely; target (“specs” | “decisions” | “all”, default “all”) selects which projection(s) to rebuild alongside or instead of it — call with target: "decisions" after recording a decision so the board sees it.
