All service metadata moves into a single `.gitmost/index.json` sidecar; the `.md`
files become clean markdown (Obsidian & any editor work directly). The page tree
mirrors the folder structure (folder = parent page; the parent's body lives in
`<Folder>/index.md`); collisions disambiguate by a `~<slugId>` filename suffix
with identity tracked by pageId in the index (safe renames, never delete+create —
backed by 5133bb34). Bare files/folders from a third-party editor are adopted into
pages. Includes the migration path off the current `docmost:meta`-in-file format
and a phased plan (each phase gated by engine unit tests + the browser e2e +
isolated shell e2e). Agreed with the owner 2026-06-24.
