/projects/{id} is read-only today, and it's the one wall we keep hitting.

Tags — completing tasks moves tags via automations (works great!), but there's no way to set or correct a tag directly when a project needs a manual nudge

Internal due date — readable via API, but not writable, so planning tools can't manage it

Just PATCH support for these two fields would close the loop for anyone building planning or reporting on top of the API. Everything else about project data is already there — this is the missing 5%. ✍
