+
+Nine duration keys now carry their unit in their name (objectstack#25762). Each one said its unit only in its description, so `timeout: 300` read as either milliseconds or seconds. After objectui merges into objectstack, `@objectstack/spec`'s `check:duration-unit-keys` judges these schemas too, and the maintainer chose to rename the keys rather than exempt them. The renames follow objectstack's own (`…Ms` / `…Seconds`, the unit each description already stated). The value and its unit do not change, only the key name. This is breaking for a document that still writes an old name; it is marked `minor` under this repository's version policy.
+
+| Node / schema | FROM | TO | Unit |
+|---|---|---|---|
+| `carousel` (`CarouselSchema`) | `autoPlay` | `autoPlayMs` | milliseconds |
+| `chatbot`, `chatbot-enhanced`, `chatbot-floating` | `autoResponseDelay` | `autoResponseDelayMs` | milliseconds |
+| `ActionSchema` | `timeout` | `timeoutMs` | milliseconds |
+| `ActionSchema.retry` | `delay` | `delayMs` | milliseconds |
+| `toast` (`ToastSchema`) | `duration` | `durationMs` | milliseconds |
+| `tooltip` (`TooltipSchema`) | `delayDuration` | `delayDurationMs` | milliseconds |
+| `hover-card` (`HoverCardSchema`) | `openDelay` | `openDelayMs` | milliseconds |

+| `report` (`ReportComponentSchema`) | `refreshInterval` | `refreshIntervalSeconds` | seconds |
+
+What an author sees with an old name:
+
+- **zod (`@object-ui/types/zod`).** The old key is still declared, as a tombstone, so it is refused at its own path with code `invalid_type`. The message names the new key: "`timeout` is now `timeoutMs` … the value (milliseconds) is unchanged." Without the tombstone, `.passthrough()` would keep the value and nothing would read it.
+- **TypeScript.** The old member is `?: never` with `@deprecated`, so a typed literal that writes it fails to compile.
+- **Renderers.** `toast`, `tooltip`, `hover-card`, the three chatbot registrations and `ReportViewer` read the new key. Their registration `inputs` and `defaultProps` use the new name too. The `useObjectChat` hook option `autoResponseDelay` is a programmatic API, not a schema key, and keeps its name.
+
+objectui has no conversion registry: ADR-0087's D2 table lives in `@objectstack/spec`. The conversion is this table plus the refusal message. To migrate, rename each key as the table shows and keep the value.

+ * can silently come back under its old name.
+ *
+ * Each old spelling stays DECLARED as a `retirementTombstone` fed by

+/**
+ * The guidance for a DURATION KEY RENAMED so its name carries its unit
+ * (objectstack#25762, maintainer decision E of the objectui → objectstack merge,
+ * objectstack#25677). After the merge, `@objectstack/spec`'s
+ * `check:duration-unit-keys` judges this package's mirrors too, and it refuses a
+ * numeric key whose unit lives only in its `.describe()` prose — the
+ * `timeout: 300` that reads as either milliseconds or seconds. objectstack
+ * renamed its own population the same way (objectstack#15679 / objectstack#15680:
+ * `…Ms` / `…Seconds`, the unit the describe already stated). Feed the ONE string
+ * to a {@link retirementTombstone} under the old spelling, beside the renamed key:
+ *
+ * ```ts
+ * durationMs: z.number().optional().describe('Auto-dismiss duration (ms)'),
+ * duration: retirementTombstone(durationKeyRenamedGuidance('duration', 'durationMs', 'milliseconds')),
+ * ```
+ *
+ * It is ADR-0087's rename-with-refusal shape adapted to this package: the old
+ * key stays DECLARED and refuses by name, pointing at the new one, so an author
+ * who still writes it is told what to write instead rather than having the value
+ * kept unread by `.passthrough()`. objectui keeps no conversion registry (the
+ * ADR-0087 D2 table lives in `@objectstack/spec`), so the refusal plus the
+ * changeset's FROM → TO table is the conversion. Only the key moves; the value
+ * and its unit are unchanged, and the guidance says so.
+ *
+ * @param retired the spelling an author may still write
+ * @param renamed the unit-carrying spelling that replaces it
+ * @param unit    the unit both spellings carry, spelled out in words
