Open in ComfyUI now stamps an extra.lm_source provenance marker
(file_path + document sha256) onto the loaded graph, which rides the
workflow draft serialization across tabs and reloads. A new
LoraManager.UpdateManagedWorkflow command (palette, menubar File group,
and an item injected into the workflow actions dropdown; disabled unless
the active graph carries the marker) serializes the current graph and
PUTs it to /api/lm/workflows/content.
The write targets the workflow document: bare .json artifacts are
rewritten in place, while zip/image containers keep their original bytes
(the SHA256 is their CivitAI identity) and receive the edited graph in
the derived .workflow.json sidecar. Optimistic concurrency via
base_sha256 rejects writes with 409 when the library copy changed since
open (force retries after user confirmation). Post-write, analysis
fields and (for .json artifacts) hash/size/modified are refreshed in the
metadata sidecar and caches.
