Read the Markdown body of a canvas together with its ETag. Use this immediately before rewriting a canvas so the update can be guarded against concurrent edits. Returns the stored body as Markdown plus a strong `etag` (also in the `ETag` header) derived from that body. Pass the `etag` unchanged as `If-Match` on v1UpdateCanvasContent; the same body always yields the same ETag. A 502 means a backend dependency was unavailable — retry later. Viewers can read; only editors can replace.
