+docs(plugin-gantt): the `object-gantt` registration no longer teaches the retired view-level `api` source
+
+Clause-②: no
+Metadata-protocol: none
+
+- **Before.** The `data` input said `{ provider: 'api', read }` "reads through that request", and the `filter` input listed "an `api` request" among the record sources the gantt reads. The spec refuses that provider by name and the gantt has no reader for it: a gantt carrying it requests neither URL.
+- **Now.** `data` names the two providers the gantt reads, `{ provider: 'value', items }` and `{ provider: 'object', object }`, and says that rows a server computes reach the gantt as an object whose plugin driver computes them, never as a request URL in the view. `filter` names the object and inline rows.
+- **Unchanged.** Text only: no input, schema, renderer behaviour or export moves. The page element's `dataSource: { provider: 'api', read, path? }` binding is a different door and is untouched.

 | `objectName` | `string` |  | ObjectQL object name. The record source is one of `data`, `staticData` and `objectName`; the `object-gantt` schema refuses a block that declares none of them, unless the node's `dataSource.object` names the object, which then lands on this key. |
 | `gantt` | `object` |  | Gantt-timeline configuration, the author face — the same block `ListViewSchema.gantt` declares, and the one the renderer validates this node against. Taken WHOLE when present: the flat top-level spelling beside it is ignored. The spec requires `startDateField`, `endDateField` and `titleField`, which name the record fields a task's bar starts at, ends at and is titled by; the other members (`progressField`, `colorField`, `dependenciesField`, `parentField`, `viewMode`, `exportFileName`, …) are optional. |
-| `data` | `object` |  | A `{ provider, … }` data-source configuration, read FIRST on the record-source ladder: a gantt carrying one never reaches `staticData` and never queries `objectName`. `{ provider: 'value', items }` charts those rows, `{ provider: 'object', object }` queries that object and `{ provider: 'api', read }` reads through that request. A bare array is not this key’s shape and is not a record source: the gantt falls through to `staticData`, then `objectName`, so inline rows belong under `staticData`. |

The gantt reads two providers: `{ provider: 'value', items }` charts those rows and never queries `objectName`, and `{ provider: 'object', object }` queries that object in place of `objectName`. Rows a server computes reach the gantt as an object whose plugin driver computes them, never as a request URL in the view.

 | `staticData` | `array` |  | Inline records, read SECOND on the record-source ladder: a `data` configuration wins and this key is then never reached, while `objectName` is read AFTER it, so a gantt carrying both charts these rows and never queries that object. `filter` and `sort` narrow and order these rows exactly as they do fetched ones. |
-| `filter` | `array` |  | Base query filter in the rule-array form `[{ field, operator, value }, ...]`, narrowing the tasks the gantt charts — from every record source it reads: the object, an `api` request, or inline rows. Context tokens such as `{current_user_id}` are resolved first, then the filter is lowered to `$filter` on the query. The MongoDB-style record form is not this key’s shape. |

 | `navigation` | `object` |  | What a task click opens — the `{ mode, size, openNewTab, preventNavigation }` block a list view declares. With the key ABSENT a click opens the task's record in a drawer, this renderer's own default. `mode` is `drawer` (the overlay), `new_window`, `page` or `none`, and a block written without `mode` takes the spec's `drawer` default. `drawer` opens the task's record in the drawer; `none` opens nothing. `page` opens the task's record page in the same tab and `new_window` opens it in a new tab. The gantt builds that address itself from the page it is on and does not use a record navigator the host publishes, so a host that publishes one changes nothing: on the object's own list or view route (`…/OBJECT/view/VIEW`) the address is the record page `…/OBJECT/record/ID`, while on any other page, such as a custom page, `/OBJECT/record/ID` is appended to the current address. The object is `data.object` when `data` is the object provider, else `objectName`; on inline rows that name neither there is no record to open, and every mode, the default drawer included, opens nothing. `preventNavigation: true` opens nothing whatever the mode, `openNewTab: true` opens the record page in a new tab and outranks every mode except `none`, and `size` sets the overlay width. |
 | `label` | `string` \| `object` |  | Gantt label — the second link of the exported PNG/PDF file-name chain, after `gantt.exportFileName` and before the bound object's own label. A string is used as written, and an inline locale map (`{ en, "zh-CN", … }`) gives the entry for the display locale. The chart draws it nowhere else. |
