+fix(analytics)!: every analytics face lowers the closed `dateRange` preset vocabulary to one window and refuses the rest with `400 ANALYTICS_DATE_RANGE_UNRECOGNIZED` (#16322)
+
+<!-- adr-0087: not-required (already-registered analytics-time-dimension-date-range-vocabulary-closed) the driver half of #16041 implements the migration that card registered; the accept set narrowed at the contract there, and the prescription an author needs is that entry's, unchanged -->
+
+**BREAKING** for an in-process caller that reaches an analytics face PAST the
+schema door with a string the closed vocabulary does not contain: it used to be
+answered, and is now refused. Shipped as `minor` under the repo's launch-window
+convention. The driver half of #16041, whose spec change closed
+`AnalyticsQuery.timeDimensions[].dateRange`'s string arm to the thirteen
+dashboard preset names; every value affected here was already refused at
+`POST /analytics/query` and `/analytics/sql` when that landed.
+
+## What was wrong
+
+#16041 closed the contract; the faces behind it never aligned, so the defect it
+abolished simply moved onto the newly-blessed vocabulary. Measured on the built
+`driver-memory` dist over five probe rows (2020, 2026-08-31, 2026-09-05, now,
+2099):
+
+| input | before | after |
+|:--|--:|--:|
+| `today` | 1/5 | 1/5 |
+| the other twelve declared presets | **5/5 — 2020 and 2099 included** | a real window each |
+| `'not a range at all'`, `'Last 7 Days'` | 5/5 | `400 ANALYTICS_DATE_RANGE_UNRECOGNIZED` |
+
+`driver-memory` recognised exactly `today`: every snake_case preset missed its
+`startsWith('last ')` branch and fell to a `[range, range]` pseudo-window whose
+two bounds were the preset's own NAME, which matched every `Date`-typed row
+under BSON cross-type ordering. Both `service-analytics` SQL strategies lowered
+the same names — and unrecognised strings, and `today` — to the point window
+`created_at >= 'last_30_days' AND created_at <= 'last_30_days'`, whose answer is
+whatever the dialect decides a vocabulary word compares as. So a dashboard
+asking for one month got all of history on one backend and a nonsense
+comparison on the other, at HTTP 200 on both.
+
+## What it does now
+
+- **One lowering, in `@objectstack/core`.** `resolveAnalyticsDateRangePreset` /
+  `resolveAnalyticsDateRangeString` resolve every declared preset to
+  `{ start, end, endExclusive }`. The window is a pair of `{date-macro}` tokens
+  handed to the existing macro resolver, so `dateRange: 'this_month'` and a
+  `{month_start}` filter token cannot answer differently, and the anchoring on
+  `AnalyticsQuery.timezone` (#16042) plus the one-calendar arithmetic (#15825)
+  come from that resolver rather than from each face.
+- **One refusal.** `analyticsDateRangeUnrecognizedError` stamps the ADR-0112
+  envelope `400 ANALYTICS_DATE_RANGE_UNRECOGNIZED` with the spec's own
+  `analyticsDateRangeRefusalMessage` wording — the same sentence the schema door
+  answers with. `driver-memory`, both SQL strategies and the draft-preview evaluator call
+  it, so "memory and SQL refuse identically" is one function rather than an
+  agreement.
+- **The upper bound keeps #16179's separation.** A window a face RESOLVED is
+  compared exclusively (`$lt` / `<`) for the ten calendar presets and
+  inclusively for the three rolling `last_N_days`, whose bound is NOW; an
+  explicit `[a, b]` a CALLER wrote is untouched and keeps `$lte`.
+- The fifteen `driver-memory` date-range pins #16041 retired are reinstated in
+  preset form (DST cells re-measured under calendar semantics, not re-spelled),
+  and one cross-face conformance fixture holds all FOUR faces to the same
+  windows and the same refusal.
+- **The draft-preview evaluator is the fourth face**, and it is in that fixture
+  for the same reason the other three are. `preview-evaluator.ts` (ADR-0037 P3 —
+  the Live Canvas preview over a pending seed draft) carried the identical
+  `[range, range]` fallback, so a valid `last_30_days` selected NOTHING there,
+  silently, while the published chart beside it answered a real window — across
+  a publish boundary the preview exists to make continuous, since publish
+  materialises the same seed.
+
+## FROM → TO
+
+Unchanged from #16041's — the spelling that is refused here is the spelling that
+was already refused at the door.
+
+| you wrote | write instead |
+|:--|:--|
+| `dateRange: 'Last 7 days'` / `'last 7 days'` | `dateRange: 'last_7_days'` |
+| `dateRange: 'last 3 months'` | `dateRange: 'last_90_days'`, or an explicit `['{90_days_ago}', '{today}']` |
+| `dateRange: '2026-01-20'` (the SQL single-day dialect) | `dateRange: ['2026-01-20', '2026-01-20']` |
+| `dateRange: ['2026-01-01', '2026-01-31']` | unchanged |
+
+The `@objectstack/spec` entry is a `PROVENANCE_WAIVERS` row only: the refusal's
+code stays registered under `@objectstack/runtime` (the door that names the wire
+vocabulary), and the waiver records that the shared constructor spelling it
+lives one package over.

+/**
+ * [#16322] THE shared `dateRange` conformance kit: the cases and the rules every
+ * analytics face is held to, written ONCE so "memory and SQL agree" is a
+ * measurement rather than an agreement.
+ *
+ * ## Why a kit and not one test file
+ *
+ * The ruling that split #16041 asked for exactly this — *"memory and SQL drivers
+ * refuse identically and share one conformance fixture"* — because the defect it
+ * closes was a DISAGREEMENT, not a bug in one backend. Measured on `b834b48e7a`,
+ * one input, three different wrong answers:
+ *
+ *   - `driver-memory` matched EVERY `Date`-typed row (a `Date` compares above a
+ *     `String` under BSON cross-type ordering, so both garbage bounds of the
+ *     `[range, range]` fallback were satisfied) — 5/5 probe rows, 2020 and 2099
+ *     included, at HTTP 200;
+ *   - both `service-analytics` SQL strategies compiled the point window
+ *     `created_at >= 'last_30_days' AND created_at <= 'last_30_days'`, whose
+ *     answer is whatever the dialect decides a vocabulary word compares as;
+ *   - and the VALID presets fared no better: `today` was the only one
+ *     driver-memory resolved, and neither SQL strategy resolved even that one.
+ *
+ * ⛔ The faces cannot be driven from one file — `packages/runtime` is the only
+ * package that can import all of them, and a new static consumer of
+ * `@objectstack/driver-memory` there is a maintainer ruling under the #6664
+ * census (`RULED_CEILING`), not a test-authoring decision. So the shape is the
+ * repo's existing cross-driver one (`*-conformance.ts` in a shared package, a
+ * thin runner per driver): the CASES and the RULES live here, each face's
+ * runner lives in its own package, and the assertion body is not written twice.
+ *
+ * ## The oracle is this package's own lowering, and that is the point
+ *
+ * Every face is compared against {@link resolveAnalyticsDateRangeString} — the
+ * one function all of them now call — so holding each face to it holds the
+ * faces to each other, transitively, without a process that can see them all.
+ * A face that grew a second interpretation goes red in its own package.
+ *
+ * ⛔ Returns FINDINGS rather than asserting: this file ships in `dist` and must
+ * not import a test framework. Each runner asserts the list is empty, so one
+ * rule set produces one failure text on every face.
