+feat(app-shell,components): the record drawer opens a related row or a lookup in place, one level at a time, and its bar names no object
+
+Clause-②: no
+Metadata-protocol: none
+
+The console's record drawer is one drawer (objectstack#26679):
+
+- **The bar.** Its left side is empty at the root: no object name and no "n / N" position. Its right side holds `↑` `↓` (previous / next through the level's sibling set, disabled at the ends; `↑` / `↓` and `k` / `j` while no text field, menu or grid has the keyboard), `⤢` (icon only) and `✕`. `NavigationOverlay` gains three optional props for it — `onBack`, `trail` and `stepper` — and keeps its title as the accessible name only, on every host.
+- **The root steps through the list.** `ListView` reports the rows it shows, in their order, through a new `onRowsChange` host prop (beside `onTotalChange`, answered by a paged grid; a board or a grouped grid reports no rows). The object page hands them to its drawer, so `↑` `↓` at the root move to the previous / next row, disabled at the first and the last.
+- **In place.** A related row, a lookup value or any record link inside the drawer opens that record in the same drawer and keeps the previous one on a stack. The bar shows `←` and the path (each ancestor returns to its level); `←` or `Esc` goes back one level, `Esc` at the root closes, `✕` closes the whole stack. `↑` `↓` one level down step through the rows the parent's related list showed, never across levels. Each level keeps its own `?tab=`. An object that declares `navigation.mode: 'page'` still opens its page.
+- **⤢ at any level** opens that record's page with the levels below it as its `?from=` trail, so its back link reads the record it was opened from; the page offers "Collapse to drawer", which returns to the drawer with the stack restored.
+- **On the record page**, a related row or a lookup opens its record in a drawer over the page, under the same rules.
+- **`data-table` inside a dialog.** A table drawn inside a dialog now opens its rows: the row click ignored every click with a dialog ancestor, so a related list inside a record drawer drew pointer rows that opened nothing. Only a dialog portalled out of the row (one that does not contain it) still stops the click.
+- **What a reload keeps.** The root stays `?recordId=` on an object list; the levels above it live in memory, so a reload shows the root record.
+
+Published-type additions, all optional: `RelatedRecordHandlers.onView` receives the ids of the rows on show as a third argument, and `RelatedList`'s `onRowClick` receives those rows as its third argument. The i18n packs gain `detail.collapseToDrawer` in all ten languages. In zh, the `⤢` label (`detail.openAsFullPage` and `console.objectView.expandToPage`, kept byte-identical) reads 整页打开.

+## The record drawer's stack
+
+A record opened from a list sits at the root of the drawer, and the root is
+**addressable**: `?recordId=` on the list's URL, so a reload, a shared link or
+Back reopens it. Records opened **inside** the drawer — a related row, a lookup
+value — open in the same drawer one level down (objectstack#26679), and those
+levels are **in-memory** state: a reload shows the root record.
+
+| State | Lives in | Survives a reload |
+|---|---|---|
+| The root record | `?recordId=` | Yes |
+| The levels above it, their titles and sibling sets | Component state | No |
+| Each level's record tab | `?tab=`, saved per level while another level is shown | The shown level's only |
+| The stack across a `⤢` round trip | Router history state, consumed once on return | No |
+
+`⤢` at any level opens that record's page with the levels below it as its
+`?from=` trail, which is addressable like any record trail. The page it opens
+offers "Collapse to drawer", which returns to the drawer with the stack it left;
+the history state that carries the stack is rewritten without it as soon as the
+drawer has it back, so a later reload or Back shows the root alone.
