Every capability below already exists on the platform; this page describes how the hub reads it from the GROUP angle rather than describing it as a new engine.
Attendance & chronic-absence triage
A chronic-absence band rolls up from a supplied attendance summary and recommends a tiered intervention -- but the recommendation is ADVISORY ONLY: it never files a truancy petition and never refers a family to court on its own. Where the enrolled-days count is missing or zero, the rate is reported as UNKNOWN, never a misleading 0%, and an unknown band routes to needs-review for a human, never silently to “on track.” A student is referenced only by an opaque roster handle.

The advisory / team anchor
A departmentalized day only has one thing that spans it: the advisory, homeroom, or team group. The scheduling engine treats that grouping as a first-class structural constraint, so the cohort holds together across five or more separate subject sections rather than dissolving into a pile of unrelated class rosters. The hub reads that SAME structural anchor to organize its view -- opaque cohort keys, never a student identity.

Counselor & MTSS caseload, in one place
A counselor's caseload and a composed student-360 read pull together the on-track picture for the students assigned to them, and a tiered MTSS support level is a data-trend FLAG a team reviews -- never a tier the system moves on its own. A sole-possession note is visible ONLY to the counselor who wrote it. Every read is fail-closed: an unauthorized viewer -- a general teacher without the capability, a parent, a rep -- gets nothing, never a leak.

Grades roll up by standard, across the group
The canonical gradebook's standards-aligned evidence rolls up to mastery PER standard, deterministically, as a report model over the existing gradebook -- not a second gradebook and not a new student table. A grade-level team reading the hub sees mastery banded by skill for the group it is responsible for, rather than opening each subject teacher's gradebook in turn. Surfaced through a consent gate; complements a school's system of record rather than replacing it.

Each teacher’s daily surfaces, read by group
Every subject teacher already has a section-scoped daily view: a seating chart, a sub plan, a parent-contact log, and an assignment roster. The seating chart and sub plan are section/room config; the parent-contact log and the assignment roster are student-coupled PII and are HONEST-OFF by design wherever no authorized store is connected -- nothing here is fabricated. The hub's job is reading those same per-teacher surfaces from the advisory/team angle, authorized-only, rather than inventing a new place to store them.

Family updates, by kind of message and by channel
A staff message to families rides the family_comms consent lane: it is addressed by email to a family that has opted in to school messages, and text and voice calls each need their own opt-in. A record notice such as an absence alert, and a school emergency broadcast, need no messaging opt-in. They are addressed by email, and a student whose family has not granted directory-information disclosure produces no recipients. Quiet hours and an email opt-out apply to that email, including the email copy of an emergency broadcast, where the account that owns the address has saved those settings for that school. If that email would arrive inside those quiet hours, it is held and sent after quiet hours end. Where no such settings are saved, quiet hours do not apply to it. The mail transport also refuses it to an address on the platform’s do-not-mail list, such as one that used a one-click unsubscribe link, hard-bounced or drew a spam complaint. The in-app copy for a guardian with a claimed account is written at once, whatever the quiet hours, and an emergency voice call is a separate lane that does not check quiet hours. A repeat of the same notice to the same guardian is not sent twice.
