+# Data model
+
+The entities the directory serves. Structured data lives in the data source (see `docs/plan.md`); blobs (photos, audio) are URL references into blob storage.
+
+## Person
+
+One record per person, all roles in one shape:
+
+- **Key**: school email, lowercased. Everyone has one, including the youngest students (their addresses exist but they don't have access yet).
+- **Names**: full name, legal name, preferred name.
+- **Roles**: student, parent, and staff booleans — combinations are valid (staff members are often also parents). Display strings derive from the flags.
+- **Pronouns**: optional; a curated list plus a freeform escape hatch.
+- **Pronunciation**: optional audio recording of the person's name.
+- **Photo**: official portrait or personal upload; people may opt for an illustrated avatar instead.
+- **Facts**: optional about-me text — first-person blurbs for students, professional bios for staff.
+- **Student fields**: grade (`Kindergarten`, `Grade 1` … `Grade 8`), classroom section, and the parent contact emails for the student.
+- **Staff fields**: job title, department, grade band.
+- **Contact**: email always; phone optional.
+- **Year rollover**: next-year grade and band, so the directory can flip to the new school year.
+
+## Family
+
+A family groups adults and kids:
+
+- **Key**: shared by all members. (Currently a parent's email; minting stable family IDs is a planned migration.)
+- **Photo and caption**: the family photo plus a who's-who description naming everyone in it.
+- **Pronunciation**: optional audio recording of the family name.
+- **Address**: as much as the family chooses to share — full postal address or just city and state.
+- **Phone**: optional family phone.
+
+## Classrooms and grades
+
+- **Classroom**: name, mascot artwork, and the grade band it serves. Some classrooms subdivide into sections (teams); sections have their own logos.
+- **Section**: classroom subdivision with up to a few teachers, a sort order, and named schedule blocks.
+- **Grade band**: pairs of grades share a band with a combined identity — `Hummingbirds` (K), `Halcons` (1st/2nd), `Jayvens` (3rd/4th), `Cospreys` (5th/6th), `Hegrets` (7th/8th) — used for browsing, room-parent organization, and band-colored styling (see `docs/design.md`). A grade → next-grade mapping drives year rollover.
+- **Room parents**: parent assignments per grade band.
+- **Departments**: ordered list organizing the staff view into sections.
+
+## Sourcing
+
+Records are imported from the school's systems and enriched by families themselves (photos, facts, pronunciation recordings, address preferences), with each contributed item carrying a last-updated stamp so refresh cadence can be enforced.
