The closed authoring vocabulary

Three closed sets. A slot’s type picks its runtime value shape; a slot’s source (direct() or derived()) picks which fact or computation fills it. This page is a selection reference — which one to pick — not a restatement of their field shapes.

Slot types

type	runtime value shape	pick it when
text	string (string | null if optional)	one editable line/paragraph (size short|medium|long)
number	number (number | null if optional)	a numeric fact with formatting
select	string (string | null if optional)	a closed set of choices the user picks from
image	ImageValue (ImageValue | null if optional)	one framed photo (add crop/frame)
image_collection	ImageCollectionValue	a gallery of framed photos
video	VideoValue (VideoValue | null if optional)	one hosted video (add frame/playback)
video_collection	VideoCollectionValue	several hosted videos
list	string[] for a text element, unknown[] otherwise	a flat list of scalar items
poi_list	PoiRow[]	neighborhood points of interest
url	string (string | null if optional)	a link the user edits in a URL field
object_list	Record<string, unknown>[]	repeating, independently-editable multi-field items

The full per-type field shapes live in your editor’s autocomplete and schema-system.md — this page is only which to pick.

direct() sources

The property facts a slot binds verbatim. A bad name is a compile error at the direct(...) call site.

Property facts (resolve once per property):

• address — the full formatted address
• listing_intent — for-sale vs. for-rent state
• status — the listing status, free text as shown on the listing (e.g. “For Sale”)
• property_type — the property type (single_family | condo_townhome | multi_family | investment)
• year_built — the year the property was built
• lot_size — the lot size, pre-formatted text

Per-unit facts (resolve against the current/single unit row):

• unit_label — the unit’s display label (e.g. “Unit 3B”)
• beds — bedroom count for this unit
• baths — bathroom count for this unit
• sqft — square footage for this unit
• price — this unit’s price, pre-formatted text
• notes — free-text notes on this unit

List sources (bind the whole array verbatim — pick these for object_list slots that repeat over every row):

• units — every unit row on the property
• contacts — every contact attached to the section

Per-contact fields (resolve against the attached contact):

• name — the contact’s display name
• title — the contact’s job title/role
• bio — the contact’s bio copy
• email — the contact’s email address
• phone — the contact’s phone number
• website — the contact’s website URL
• instagram — the contact’s Instagram handle/URL
• linkedin — the contact’s LinkedIn handle/URL
• x — the contact’s X (Twitter) handle/URL
• facebook — the contact’s Facebook handle/URL

Contact images (bind only to image slots):

• headshot — the contact’s headshot photo
• logo_dark — the contact’s logo, dark-background variant
• logo_light — the contact’s logo, light-background variant

derived() transforms

Computed values, grouped by family. A bad name is a compile error at the derived(...) call site.

transform	what it computes
units.bedsPrimary	beds of the primary (lowest-position) unit
units.bathsPrimary	baths of the primary unit
units.sqftPrimary	sqft of the primary unit
units.pricePrimary	price of the primary unit, pre-formatted text
units.bedsRange	formatted beds range across all units (e.g. “2–4”), collapsing to one value when uniform
units.priceStart	the lowest numeric unit price; falls back to the first non-numeric price (e.g. “Sold”) when none is numeric
units.bedsMin	the minimum beds across all units, formatted
units.bedsMax	the maximum beds across all units, formatted
units.bathsMin	the minimum baths across all units, formatted
units.bathsMax	the maximum baths across all units, formatted
units.sqftMax	the maximum sqft across all units, formatted
address.line1	the property address’s street line
address.line2	the property address’s city/state/zip line
contact_address.line1	a contact’s address street line
contact_address.line2	a contact’s address city/state/zip line
clock.currentYear	the current year (e.g. for a copyright line)
coordinate.lat	latitude, split from the property’s geocode
coordinate.lng	longitude, split from the property’s geocode
