With a `from` selector (a grantId from that list), returns that person's shared profile text. SAVED BY NAME: if the user has saved a context under a short name, pass `saved` (that exact name) to pull it - the service resolves the name to the real source (a share, a teammate, a @handle, or one of the user's own projects) and re-checks access live every time. If that access is gone (revoked, expired, left the team, or closed), it returns a calm \"no longer available\" note instead of an error. NETWORK: if you already know a member's project @handle, pass `handle` to pull the context they have opened to the UseMyContext network - their live composite, read-only. Each @handle addresses ONE specific project, so the handle alone identifies what to read. ORGANISATION: if you and another person are members of the same UseMyContext team/organisation on an active team plan, pass `org` (the organisation id) and `member` (that teammate's member id) to read their live composite - their curated context only, never their files or facts. Profiles whose owners set them to public visibility are browsable anonymously at https://usemycontext.ai/directory; for private, shared, network, or team contexts you must already know the saved name / handle / org + member ids.
