Cells

The categorical value: a string, number or boolean, exactly as broad as what body-cell.tsx passes through.

labelMap is looked up on the text key (String(value)), so a boolean column keys on 'true' / 'false' -- the same shape meta.filterOptions and meta.statusTones already use.

date-fns locale object. Omitted? Then the cell follows the language of the grid itself (locale/calendarLocale on <ActiveGrid>), just like the date filter in the column header.

The preset name, or nothing to inherit the ordinary human date form of the grid's presentation. Without a resolved form the platform fallback SHORT_TEXTUAL applies.

A preset, never a free date-fns pattern. The default is the same resolved form formatSemanticDate uses, so the date column type and this cell cannot render one semantics in two forms.

What the value means, and therefore how it is read.

• 'date-only' (default): a calendar fact -- date of birth, start date, contract, policy or pension date. The cell shows the same day in every time zone.
• 'datetime': a moment -- createdAt, an audit or execution moment. The cell shows that in the zone of the reader, because that is what a moment is supposed to do.

Date-only is the default because that is what this cell gets in practice: body-cell.tsx renders it for columns with meta.filterType: 'date', and a column that really shows a moment goes through the dateTime preset, which brings its own valueFormatter and therefore never reaches this cell.

Never read a date-only value with new Date(value): an ISO date-only string is UTC midnight, and west of UTC it formats as the previous day.

The link text, and at the same time the argument of an href function.

Stays string: a link carries text. The guard below is however the same as in BadgeCell, so that a cast-in 0 does not silently remove a cell.

The generic UI tone. Mandatory: a status cell without a tone is a categorical badge, and BadgeCell exists for that.

The mapping from domain value to tone belongs to the caller — in the column configuration through meta.statusTones, or here at the call site when the cell value is not a stable key (a derived or translated value).

The already resolved status label.

Deliberately `string` and not broader. The key of a status column is String(value), and the mapping key → tone lives in meta.statusTones; body-cell.tsx resolves that pair together and passes the outcome on here. Widening this type would invite a call site to pass a raw domain value, and thereby put a second key derivation next to the existing one.

The emptiness guard below is nevertheless the same as in BadgeCell, as defence in depth: a call site that does push a false or 0 through a cast does not lose a cell by it.

What the text is, for the bidi policy: free text (text, the default) takes its direction from its first strong character, a formatted value (value) and the grid's own words (ui) inherit.

The column's declared meta.textDirection; wins for text and value.
