+feat(spec): make the dashboard date-range preset names a single vocabulary and check a date filter's `defaultValue` against it (#4614)
+
+A dashboard's built-in `dateRange` validated its preset name and a
+`globalFilters` entry of `type: 'date'` did not, so the same typo was an
+author-time error on one surface and a silent wrong answer on the other.
+
+`GlobalFilterSchema.defaultValue` is `string | number | boolean`, which makes a
+bare preset name the only spelling available for a date filter's default —
+and nothing checked it. An unrecognised name cannot be lifted to a range, so it
+fell through to "a bare string date means equality on that day" and reached the
+backend as `created_at = 'last_7_dayz'`: a condition no row matches, answered
+`200 OK` with a zero. Every tile read `0` while the filter bar showed
+"All time", so the dashboard looked deliberately empty rather than
+misconfigured — the failure mode that costs the most time to diagnose, and the
+one an AI author reads as a correct answer and builds on.
+
+- **`DATE_RANGE_PRESETS`** (+ the `DateRangePreset` type) is new in
+  `@objectstack/spec/ui` and is now the vocabulary's single source of truth.
+  The thirteen names existed three times before this: inline in
+  `dateRange.defaultRange`, as `PRESET_RANGES` in objectui's
+  `dashboard-filters` (the module that maps each name to its date-macro
+  bounds), and as a hand-written table in the dashboard docs.
+- **`DATE_RANGE_DEFAULT_RANGES`** (+ `DateRangeDefaultRange`) is the presets
+  plus the `custom` sentinel, and is what `dateRange.defaultRange` now reads.
+  `custom` is deliberately not a preset — it names no window, it opens the
+  picker — so it stays legal there and is rejected as a bare filter default,
+  which has no `from`/`to` for it to hand over. `defaultRange`'s accepted set
+  is otherwise unchanged by the extraction, and a test asserts that member for
+  member.
+- **`GlobalFilterSchema` gained a `superRefine`**: on `type: 'date'`, a
+  declared `defaultValue` must be a preset name, an ISO date (`2026-01-15`,
+  optionally with an instant), or a known date-macro token (`{today}`,
+  `{30_days_ago}`). The macro half asks `isDateMacroToken` rather than
+  restating its grammar, so there is one token vocabulary and no second dialect
+  to drift. The rejection quotes the offending value back and lists all three
+  legal spellings, because a dashboard with several date filters otherwise
+  gives no clue which one is wrong. Every other filter type is untouched — a
+  `select` filter's values are the author's own vocabulary.
+
+**Existing metadata is unaffected.** The tree's only date-filter default is
+`system_overview.dashboard.ts`'s `last_7_days`, which is a valid preset and is
+pinned by a test; a corpus scan of the three example apps and the docs found no
+misspelled preset name, so no ADR-0087 conversion is required. The accepted set
+is a strict superset of what objectui's renderer resolves today, so no
+declaration that used to render can stop parsing.
+
+The new exports and the `.describe()` on `defaultRange` are additive; the only
+authorable behaviour that changes is that a value which previously parsed and
+then silently resolved to nothing is now an author-time error.

+A `type: 'date'` filter's `defaultValue` must be a value the dashboard can
+actually resolve to a window. Three spellings qualify:
+
+| Spelling | Example | Means |
+| :--- | :--- | :--- |
+| Preset name | `last_7_days` | The preset range of that name (table above) |
+| ISO date | `2026-01-15`, `2026-01-15T08:30:00Z` | That day exactly |

+Anything else is rejected at author time. This matters because the failure it
