upload_assetUpload one image (reserve → presigned PUT → complete) and return an `asset://<key>` reference to embed as ``. Provide the image as **either** `data_base64` (inline base64) **or** `file_path` (a local file the server reads) — exactly one; with `file_path`, `filename` defaults to…append_to_markdownAppend to an existing file with optimistic concurrency (GET current → concat → conditional PUT with `base_version_no`). Auto-retries once on conflict, then surfaces `CONFLICT`. Accepts `commit_message` — a recommended 1-2 line change summary shown in the version history.edit_markdownChange PART of a file by exact literal replacement (read → apply → conditional PUT with `base_version_no`; auto-retries once on conflict, re-applying every edit). Pass several changes at once as **`edits: [{old_string, new_string, replace_all?}, …]`** (max 50, applied in order) — they land as **one…update_markdownReplace a file's ENTIRE content. Pass `expected_version` for optimistic concurrency (mismatch → `CONFLICT`); omit it to force LWW. Passing `expected_version` for a path that does **not** exist now returns `CONFLICT` (`detail.server_version_no` = `0`), not a silent create. For a partial change use `…restore_versionRoll a file back to an earlier `version_no` (from `list_versions`): that version's content becomes a NEW current version — history is immutable, so the rollback is itself undoable. Restoring the version the file is already on is an accepted no-op. Accepts `commit_message`.get_markdownRead a file's content by path (materializes inline content or a presigned content URL for large docs). Pass `version` (a `version_no` from `list_versions`) to read an old immutable version.list_versionsList a file's immutable version history, newest first (`version_no`, `commit_message`, author, `registered_at`, size).delete_markdownSoft-delete a file. Requires `confirm:true` (otherwise `VALIDATION`); resolves the path to a document key first.create_foldermkdir -p` — create every missing segment; already-existing folders count as success.list_foldersReturn the full folder tree.list_filesList the documents and immediate subfolders inside a folder path.search_markdownSearch by TITLE (substring) + BODY full-text (current versions; whole-word match, ranked, body hits include a snippet).- +4 more on the listing page
