pub const CREATOR_SESSION_PREFIX: &str = "creator:session=";Expand description
Tag prefix carrying the short session id of the writer (issue #202).
Why: when a session UUID is already attached as a bare tag, the TUI
activity panel cannot easily pick it out of the tag list. Emitting a
dedicated creator:session=<first-8> tag puts the session shorthand
in the same reserved namespace as the rest of the attribution data so
the dashboard / TUI can render it without bespoke parsing.
What: prefix string; the suffix is the first 8 hex characters of the
originating UUID.
Test: session_tag_from_tags_returns_first_uuid_short.
