PULL now serializes each page as the native-Obsidian format (serializePageFile: a minimal gitmost_id frontmatter + the fixpoint markdown body) instead of the heavy docmost:meta envelope. title/parent/space are derived (filename / folder / repo), so only the pageId is persisted. readExisting recovers identity from the gitmost_id frontmatter (parsePageFile) instead of docmost:meta. Extracted stabilizePageBody() (the export->import->export fixpoint, no meta) so the native writer and the legacy serializer share the same deterministic body — re-pulls of an unchanged page stay byte-identical (loop-guard). Tests: read-existing fixtures rewritten to gitmost_id; apply-pull asserts the written text is native frontmatter and carries NO docmost:meta (regression guard). 611 engine tests green. NOTE: PUSH still reads docmost:meta — the end-to-end cycle is intentionally NOT runnable until phase 3 (PUSH reads frontmatter + derives title/parent from path) lands; no vault is wiped/deployed until then.
