Deeper glossary entries for contact, cursor pagination, fallback channel, GSM-7, and panic button
Five glossary entries that named a term but only gave the generic industry definition now carry an Orbit-side paragraph with the concrete API field or dashboard control behind the term — the segments endpoint for a contact, the cursor format for messages pagination, the fallback chain response on notify, the GSM-7 vs UCS-2 segment-cost difference on a send, and where the agent distress alert lives on the softphone.
Several glossary entries defined a term in its generic telecom-industry sense without the Orbit-specific behavior that makes the term useful inside this platform. The entries now keep the one-line industry definition and add an Orbit paragraph below it, matching the depth the rest of the glossary already carries.
- **Contact** — the identity-resolution and segments surface: repeated identifiers fold onto one contact record, and audience segments are built and refreshed through the contacts segments endpoint.
- **Cursor-Based Pagination** — the messages list returns an opaque next_cursor whose value is a keyset token, so paging through a growing inbox never reskips or skips a row.
- **Fallback Channel** — a notify send walks an ordered channel chain, returning the binding that queued as active, the bindings rejected synchronously as skipped, and the pending hops as fallback_chain, with a cumulative cost cap that drops later hops rather than advertising a channel that will never be attempted.
- **GSM-7** — a single non-GSM-7 character forces the whole body into UCS-2 and re-encodes it, dropping the per-segment budget from 160 to 70 characters and changing the billable segment count the message API returns.
- **Panic Button** — the softphone label for the agent distress alert, distinct from the API and audit vocabulary ("distress"), including that a press forces recording on and persists a durable, audited incident.
